[0121] FIG. 11 a perspective view of a holding device of a radiology holding device according to the invention according to the second exemplary embodiment.

[0122] FIG. 1 shows a view of a first exemplary embodiment of the radiology system 100 according to the invention. The radiology holding device 1 is shown in a sectional view, while the radiology apparatus 50, such as an X-ray apparatus 51, MRT apparatus 52, CT apparatus, or a radiotherapy apparatus 54, is shown in a front view. The radiology holding device 1 comprises an attachment device 2, which pivotally accommodates and bears the supporting arm 3. The supporting arm 3 comprises an axle component 4, which is pivotally fixed to the attachment device 2, and a supporting component 5.

[0123] The attachment device 2 is presently configured as an attachment console and is fixedly mounted to the ceiling of a radiology room (not shown). The shield 18 is centrally disposed on the axle component 4, covering the opening, which is formed by means of the passage of the supporting arm 3 through the magnetically shielding intermediate ceiling. In the case that the radiology holding device 1 does not pass through an intermediate ceiling, the shield 18 is preferably configured such that it completely encloses the attachment device 2.

[0124] The radiology holding device 1 is disposed in the vicinity of a radiology apparatus 50, such as an X-ray apparatus 51, MRT apparatus 52, CT apparatus 53 or radiotherapy apparatus 54. The supporting arm 3 can be pivoted over the patient treatment table 26, so that the holding device 9 is readily accessible for a patient.

[0125] Along the supporting component 5, two receiving rails 23 are configured with multiple hooking points 24 over the entire length of the supporting component 5. In a hooking point 24 of the receiving rail 23, a holding device 9 is hooked, which a patient can hold on to for support during shifting and positioning. An infusion bag 30 may also be hooked into a hooking point 24 of the receiving rail 23. A hooking point 24 of the receiving rail 23 is configured as a “valley” between two “hills” in the contour of the receiving rail 23. A tensile load applied on the holding device 9, as in normal use, fixes the position of the holding device 9 in the hooking point 24 in a form-fit due to the “valley” geometry. The holding device 9 comprises a motor-driven or preferably mechanically, spring-driven belt unit 32, by means of which the length of the holding device 9 is variably adjustable. A support hook 29a for the holding device 9 is disposed at the end of the supporting component 5. The holding device 9 can be placed across the support hook 29a, so that it does not interfere when pivoting the supporting arm 3.

[0126] Two receiving rails 23 are configured on the supporting component 5 immediately radially adjacent to the grip knob as an actuating member 12. Each of the receiving rails 23 comprises multiple hooking points 24. The hooking points 24 are configured as “valleys” in the contour of the receiving rail 23. In the hooking points 24, a holding device 9 formed by a grip and two hook members, is hooked into the outermost hooking point 24. The “valleys” of the receiving rail 23 serving as hooking points 24 are separated from one another by “hills” in the contour. A tensile load as applied in normal use fixes the position of the ring loop of the holding device 9 in the hooking point 24. The holding device 9 can readily be pushed into another hooking point 24 over a “hill”, without having to remove a leg of the hook. This provides a safe construction showing load capacity.

[0127] The actuation of the actuating mechanism 8 allows to transfer the supporting arm 3 locked in the locking position 7 by the locking device 6, to a rotary position, counter to the force of the biasing device 17. In the rotary position, the supporting arm 3 is pivotable around the rotation axis 4a of the axle component 4.

[0128] The transfer component 11 is configured as a flexible pull member 19 and connected with the locking device 6. The transfer component 11 is configured as a pull rope, which passes through the hollow section of the axle component 10 axially downwardly, outwardly out of the axle component 4, and guided and disposed radially along the supporting component 5. One of the actuating members 12 can actuate the actuating mechanism 8. A protective sleeve 27 is disposed on the transfer component 11 as a protection from contamination. They are formed by the cable loop, i.e. the transfer component 11, and a knob or the like.

[0129] The knob as the actuating member 12 is disposed immediately adjacent to the receiving rail 23. This allows a comfortable and simple actuation.

[0130] FIG. 2 shows a plan view of the radiology system 100, comprising a radiology apparatus 50 and a supporting arm 3 according to the first exemplary embodiment. The attachment device 2, see FIG. 1, is not illustrated, so that the locking device 6 is visible in a top view. The supporting arm 3 is pivotable around the rotation axis 4a of the axle component 4 configured as a tube section.

[0131] The locking device 6 comprises a fixing member 13 which is fixed to the supporting arm 3 and is biased in the locking position 7 by the biasing device 17. The fixing member 13 is configured as a bolt which engages in a depression 14 of a hole circle 15 of the locking device 6. The diameter of the depressions 15 is noticeably larger than the diameter of the axle component 16. Thus, the locking device 6 can be disposed in a simple structure, radially outwardly of the axle component 4, enabling safe fixing.

[0132] A limiting device 25 for the rotational angle is provided. The limiting device 25 for the rotational angle is configured as a mechanical stopper which limits the rotational angle of the supporting arm 3. The stopper is fixed in a depression 14.

[0133] A shock device 28 protects the supporting arm 3 from shocks and against damage. Simultaneously, the shock device 28 constitutes effective protection against damaging other objects.

[0134] On the holding device 9, a patient supporting unit 31 is fastened, which the belt unit 32 can displace upwardly and downwardly.

[0135] The housing of the belt unit 32 may be provided with an operating knob 31a (see FIG. 11), which serves for the actuation of a reel-up unit driven e.g. by a winding spring (not visible since disposed in the interior). When operating the knob 31a, the belt can be automatically retracted and reeled up (not subjected to a load) or the belt can be pulled out, against the force of the winding spring. Preferably, a belt length of at least 200 or 300 mm is provided. In advantageous configurations, the extendible belt length may be 500 mm or 750 mm or more. In high-ceilinged rooms this offers the advantage that, when not in use, the holding grip of the holding device 9 can be raised high enough so as to not be in the way when not in use, and hitting one's head is prevented. Alternately, it is also possible to hang the holding grip not in use in one of the hooks 5a.

[0136] FIG. 2 shows in a broken line a variant where the supporting arm 3 is accommodated or configured on the radiology apparatus 50. The advantage thereof is that the attachment device 2 is accommodated directly on the radiology apparatus 50, so as to enable a compact structure on the whole.

[0137] The hooks 5a shown in the FIGS. 1 and 2 allow hanging objects. For example, infusion bags may be attached thereto, or patient documentation appended thereon. The hooks 5a may be attached on, e.g. welded to, the sides of the supporting component 5. It is also possible to accommodate and attach the hooks 5a to the supporting component, stationary or displaceably, by means of tube clamps or specific attachment systems.

[0138] FIG. 3 shows an enlarged sectional view of an axle component 4 and part of the supporting component 5 of the radiology holding device 1 according to the first exemplary embodiment. The attachment device 2 is configured as an attachment console. The attachment device 2 can be fastened by screwed connection to the ceiling of the radiology room—not shown. The pivotable supporting arm 3 is accommodated and supported on the attachment device 2. To this end, the pivotable axle component 4 is directly connected with, and disposed on, the attachment device 2. The supporting component 5 extends transverse to the axle component 4. The supporting arm 3 is pivotable around the central rotation axis 4a of the axle component 4.

[0139] The axle component 4 is passed through an intermediate ceiling. The intermediate ceiling is merely outlined by the broken lines, not illustrated completely.

[0140] A shield 18 is disposed centrally on the axle component 4. Thus, the aperture in the intermediate ceiling is closed and covered. A magnetic shielding located in or on the intermediate ceiling can thus be effectively covered and closed. The shield 18 comprises a magnetic shielding, so that the remaining aperture of the magnetic shielding is as small as possible.

[0141] The locking device 6 locks the supporting arm 3 by a fixing member 13 in the locking position 7 shown. As a rule, it is biased in the locking position 7 by a biasing device 17, presently configured as a coil spring. The supporting arm 3 is non-rotatably fixed in the locking position 7. Thus, safety of using the radiology holding device 1 can be ensured.

[0142] The actuating mechanism 8 can operate the locking device 6. The fixing member 13 is connected with the transfer component 11. The transfer component 11 is configured as a flexible pull member 19, specifically as a pull rope.

[0143] The transfer component 11 is radially guided to the axle component 4 by means of a guide roller 21. The transfer component 11 is radially guided by a guide unit 20, through the wall of the axle component 4, from the outside to the inside (and vice versa). Inside the axle component 4, the transfer component 11 is guided by the guide unit 20 along the axis of the axle component 4. The guide unit 20 is presently configured as a tube. The tube is bent for deflecting the transfer component 11.

[0144] At the lower end of the axle component 4, the transfer component 11 is axially passed out of the axle component 4. At the lower end of the axle component 4, a deflection sleeve 22 is attached. The deflection sleeve 22 is configured as a conical tube section or sleeve. The deflection sleeve 22 is preferably manufactured of a plastic showing a particularly slidable and smooth surface, thus offering low frictional resistance. This allows to deflect the transfer component 11 in a small radius in the direction of the supporting component 5 of the supporting arm 3. The supporting component 5 may be a separate part, or it may be configured integrally with the supporting arm 3.

[0145] The transfer component 11 is passed through the intermediate ceiling inside of the axle component 4. Thus, it does not require a separate guide through the intermediate ceiling outside of the axle component 4. An opening in the intermediate ceiling is therefore clearly smaller than with a pull rope simply hanging down straight and in parallel to the axis of the axle component 4. The required opening of the magnetic shielding in an intermediate ceiling is clearly smaller and easier to close than in the designs known in the prior art.

[0146] At the supporting component 5, the transfer component 11 is deflected along the axis of the supporting component 5, and guided further along the axis of the supporting component 5. The transfer component 11 forms a cable loop which is guided on another guide member. A knob is attached on the radially outwardly side of the guide member. The knob and the cable loop both serve as actuating members 12, which can actuate the actuating mechanism 8.

[0147] Two receiving rails 23 are configured on the supporting component 5 immediately radially adjacent to the knob as the actuating member 12. Each of the receiving rails 23 comprises multiple hooking points 24. The hooking points 24 are configured as “valleys” in the contour of the receiving rail 23. In the hooking points 24, a holding device 9 formed by a grip and two ring loops, is hooked into the outermost hooking point 24. The “valleys” of the receiving rail 23 serving as hooking points 24 are separated from one another by “hills” in the contour. A tensile load as applied in normal use fixes the position of the ring loop of the holding device 9 in the hooking point 24. The holding device 9 can readily be pushed into another hooking point 24 over a “hill”, without having to open a ring loop. This provides a safe construction showing load capacity.

[0148] FIG. 4 shows a view of the radiology system 100 according to the invention according to the second exemplary embodiment. Here, the transfer component 11 configured as a flexible pull member 19, is guided horizontally along the supporting arm 3. A total of three force direction units 200 are provided. The force direction units 200 ensure actuation at a consistent actuation travel 19a.

[0149] The attachment device 2 is presently configured as an attachment console and is fixedly mounted to the ceiling of a radiology room (not shown). The shield 18 is centrally disposed on the axle component 4, covering the opening, which is formed by means of the passage of the supporting arm 3 through the magnetically shielding intermediate ceiling. In the case that the radiology holding device 1 does not pass through an intermediate ceiling, the shield 18 is preferably configured such that it completely encloses the attachment device 2.

[0150] In the hooking points 24, a holding device 9 is provided, formed by a grip showing at least one hook member 35. The holding device 9 is illustrated and described in FIG. 11 in detail.

[0151] The actuating mechanism 8 comprises a total of three transfer components 11, all of which are configured as flexible pull members 19, and more precisely, as pull ropes. Here, the first transfer component 11 is connected with the locking device 6. Here, the first transfer component 11 is configured as a pull rope, which is guided outwardly through the hollow section of the axle component 10, axially downwardly, out of the axle component 4, and is radially guided toward, and disposed at, the supporting component 5. Here, the first transfer component 11 shows another transfer component 11 connected therewith by means of a coupling unit 206, and passed radially further outwardly along the supporting component 5. The second pull member 19 extends horizontally along the supporting component 5, guided up to the force direction unit 200. The flexible pull member 19 is guided on the force direction unit 200 and deflected downwardly. Here, two force direction units 200 are disposed, so as to transmit an operating force introduced into the flexible pull member 19, directly to actuating the locking device 6. A third transfer component 11 is connected to the central force direction unit 200 by means of another coupling unit 206. A force direction unit 200 is likewise provided for the third transfer component 11.

[0152] Here, the force direction units 200 comprise a holding part 201 each, which is fixedly connected with the supporting component 5 of the supporting arm 3. In the vicinity of the retaining member 201, a support part 203 is disposed on the flexible pull member 19 and connected with the flexible pull member 19 in a force-fit. When a user pulls the actuating member 12, the support part is moved on the holding part 201 of a force direction unit 200, whose radial distance 34a to the actuating member 12 is longer. Thus, the force transfer inside of the transfer component 11 is transferred controlled to the locking device 6. In actuation, the flexible pull member 19 cannot be pulled reversely out of the leading holding part 201. This preferably provides a short and defined actuation travel 19a.

[0153] A grip knob of the actuating member 12 is disposed immediately adjacent to the receiving rail 23. This allows a comfortable and simple actuation. A holding part 201 is disposed radially outwardly of the attachment device 2, approximately at half the length 34 of the supporting component 5 of the supporting arm 3. The second holding part 201 is disposed at a radial distance 34 corresponding to approximately 75% of the length 34 of the supporting arm 3 of the radiology holding device 1. This allows comfortable actuation by users in the vicinity of the holding device 9. Moreover, the force for pivoting can thus be introduced, in the case of a large radial distance 34a from the rotation axis 4a, i.e. involving a long lever arm.

[0154] When actuating the locking device 6 by the first actuating member 12 showing the shorter radial distance 34a to the rotation axis 4a, it is advantageously ensured by way of the force direction unit 200 disposed at a larger radial distance 34a, that the pull member is not pulled out of the guide of the holding part 201. The support part 203 prohibits movement of the flexible pull member 19. Thus, the operating force is transferred directly to the locking device 6 for actuation. The flexible pull members 19 cannot unintentionally or undefinably sag due to the force direction units 200. The actuation travel 19a is defined and definable by the force direction unit 200. Substantially, the actuation travel 19a corresponds to the stroke length required for actuation of a fixing member 13, which is pulled out of a depression 4 of the locking device 6 for transferring the supporting arm 3 to the rotary position.

[0155] FIG. 5 shows a plan view of the radiology system 100, comprising a radiology apparatus 50 and a supporting arm 3 according to the second exemplary embodiment. The attachment device 2, see FIG. 4, is not illustrated, so that the locking device 6 is visible in a top view.

[0156] The three force direction units 200 are laterally disposed along the supporting component 5 of the supporting arm 3. The holding parts 201 of the force direction units 200 comprise and guide the flexible pull members 19. The support parts 203 are fixedly connected with the flexible pull members 19. When actuated, the support parts 203 move together with the flexible pull member 19. The actuating members 12 are not illustrated here.

[0157] FIG. 6 shows an enlarged sectional view of an axle component 4 and part of the supporting component 5 of the radiology holding device 1 according to the second exemplary embodiment, cf. region I in FIG. 4. The attachment device 2 is configured as an attachment console. The attachment device 2 can be fastened by screwed connection to the ceiling of the radiology room—not shown. The pivotable supporting arm 3 is accommodated and supported on the attachment device 2. To this end, the pivotable axle component 4 is directly connected with, and disposed on, the attachment device 2. The supporting component 5 extends transverse to the axle component 4. The supporting arm 3 is pivotable around the central rotation axis 4a of the axle component 4.

[0158] The locking device 6 locks the supporting arm 3 by a fixing member 13 in the locking position 7 shown. The fixing member 13 is biased in the locking position 7 by a biasing device 17, presently configured as a coil spring. The supporting arm 3 is non-rotatably fixed in the locking position 7. Thus, safety in using the radiology holding device 1 can be ensured.

[0159] The actuating mechanism 8 can operate the locking device 6. The fixing member 13 is connected with the transfer component 11. The transfer component 11 is configured as a flexible pull member 19, more precisely as a pull rope.

[0160] The transfer component 11 is radially guided to the axle component 4 by means of a guide roller 21. The transfer component 11 is deflected by the guide roller 21 and guided by a guide unit 20 inside of the axle component 4 along the axis of the axle component 4 through the guide unit. The guide unit 20 presently comprises a tube. The tube is bent for deflecting the transfer component 11.

[0161] At the lower end of the axle component 4, the transfer component 11 is axially passed out of the axle component 4. At the lower end of the axle component 4, a deflection sleeve 22 is attached. The deflection sleeve 22 is configured as a conical tube section or sleeve. The deflection sleeve 22 is preferably manufactured of a plastic showing a particularly slidable and smooth surface, thus offering low frictional resistance. This allows to deflect the transfer component 11 in a small radius in the direction of the supporting component 5 of the supporting arm 3. The supporting component 5 may be a separate part, or it may be configured integrally with the supporting arm 3.

[0162] At the supporting component 5, the transfer component 11 is deflected in the horizontal direction along the axis of the supporting component 5, and guided further along the axis of the supporting component 5. A second transfer component 11 is connected with the first transfer component by the coupling unit 206. The force direction unit 200 ensures an optimal transfer of the introduced operating force. An undefined and above all, unintended sagging of the flexible pull member 19 is prevented.

[0163] FIG. 7 shows an enlarged illustration of a region of the supporting arm 3 with a force direction unit 200 in the actuated state of the radiology holding device 1 according to the second exemplary embodiment, see region II in FIG. 4. The holding part 201 of the force direction unit 200 is firmly connected with the supporting component 5 of the supporting arm, for example by screw-connection or welding, enclosing the flexible pull member 19 sleeve-like. The support part is accommodated on the flexible pull member 19 by force-fit. The spherical support part 203 is firmly connected with the pull rope. The position of the support part 203 on the flexible pull member 19 is adjustable variably.

[0164] A contour layout 202 of the holding part 201 expands with increasing distance 34a from the rotation axis 4a. This allows to advantageously deflect the flexible pull member 19 on the holding part 201 so as to enable actuation of the locking device 6. The contour layout 202 of the holding part is funnel-shaped. The pull member 19 is deflected downwardly, where the actuating member 12, not shown, is disposed.

[0165] The support part 203 is configured spherical and hollow inside. The pull member 19 is passed through the support part 203. The pull member 19 is configured with a node section 204 which is accommodated inwardly on the support part 203. Moreover, the support part 203 comprises a screw unit 205, which is configured as a setscrew. The pull member 19 passes through the setscrew. The setscrew is screwed into the support part 203. Thus, the support part is connected with the pull member 19 in a force-fit.

[0166] The spherical support part 203 can be accommodated on the holding part 201 of the force direction unit 200. The support part 203 is centered on the rotationally symmetrical, sleeve-like holding part 201. The pull member 19 shows another pull member 19 connected in a force-fit by means of a coupling unit 206. This coupling unit is formed by a node section 204. The further pull member 19 is disposed on the first pull member 19 in a force-fit by way of the node section 204, and firmly connected therewith. This coupling unit is formed by a node section 204. The further pull member 19 is disposed on the first pull member 19 in a force-fit by way of a node section 204.

[0167] FIG. 8 shows an embodiment of the coupling unit 206 in a sectional view according to the second exemplary embodiment. The coupling unit 206 comprises a sleeve part 207. Two transfer components 11 are disposed inside of the sleeve part. One node section 204 each is configured on the transfer components 11, presently configured as flexible pull members 19. The sleeve part 207 of the coupling unit 206 is closed by a screw unit 208. The screw unit 208 is presently configured as a setscrew, through which one of the pull members 19 passes. In a closed state, the two pull members 19 are connected in a force-fit. The illustration of the pull member 19 by broken lines is intended to illustrate a conceivable arrangement of the flexible pull member 19 on the coupling unit 206. Moreover, further arrangements and connections of the pull members 19 are possible and conceivable. This also applies to the following Figures.

[0168] FIG. 9 shows a sectional view of a support part 203 of the force direction unit 200 according to the second exemplary embodiment. The support part 203 is configured spherical. The support part 203 is configured as a spherical sleeve part 207. The pull member 19 is accommodated on the support part 203 by means of a node section 204 configured thereat. The support part is closed by the receiving unit 205, presently configured as a screw unit 205, so that a force-fit connection is provided. The support part 203 can be disposed in almost any desired position of the flexible pull member 19.

[0169] FIG. 10 shows a sectional view of the supporting component 5 of the supporting arm 3 of the radiology holding device 1, transverse to the axis of the supporting component 5 according to the second exemplary embodiment, see region III in FIG. 4. The holding part 201 is laterally disposed on the supporting component 5. The holding part 201 encloses and guides the flexible pull member 19. The support part 203 is not illustrated. It is also possible for the pull member 19 to be passed through a hollow section of a tube element 36 of the supporting component 5. Thus, the transfer component 11 is advantageously protected from contamination. Users cannot be entangled in the pull member 19. In this case, the risk of injury is particularly minimized.

[0170] FIG. 11 shows a perspective view of a holding device 9 for a radiology holding device 1 according to the invention according to the second exemplary embodiment. The holding device 9 comprises a hook member 29, with which the holding device can be received in a hooking point 24 of the receiving rail 23. Another support hook 29a is disposed on the holding device 9 to accommodate additional objects, such as an infusion bag 30. The holding grip 31 can advantageously be flipped up and hooked into the support hook 29a. This minimizes the risk of injury and shocks. The long legs of the hook allows large retaining angles 35 of up to 60° and more, without risking that the leg of the hook slips out of the receiving rail 23.

[0171] In FIG. 11, one can identify the knob 31a, which is configured on the belt unit 32 and presently, on the holding grip of the holding device 9, to pull out the belt 32e by way of a winding spring, not visible and disposed in the interior, or against the tensioning force of the winding spring. The holding grip is accommodated on the rod 32b for rotation with the belt unit 32. The belt unit 32 is accommodated for pivoting via the sliding member 32c. The sliding member 32c serves as a bearing unit and is accommodated between the upper bracket of the holder 32a and the enlarged head 32d of the rod 32b, to as to enable easy-glide pivoting of the belt unit in the direction toward a patient. Although the belt 32e can basically twist around itself, it may cause problems in operation if the belt is wound skewed and not properly.
