DETAILED DESCRIPTION

[0056] FIG. 1 illustrates a system 1 which serves to support an operator, such as a surgeon, in his or her work on the patient, in particular in his work on the operating table.

[0057] The system 1 has an operating chair 2 and a restraining device 5. The operating chair 2 has a base frame 3 which can be placed on the floor. A pivotable column 22 is arranged on the base frame 3. The column 22 is height-adjustable, for example by means of a servomotor. The height-adjustable column 22 is connected to the base frame 3 via a joint device 23. The joint device 23 defines a pivot axis 24 about which the operating chair 2 can be pivoted sideways. Furthermore, a pivot device 25 is arranged on the operating chair 2, with which a pivot movement of the operating chair 2 can be supported. The pivot device 25 can, for example, be actively controlled by an electric motor. A seat 4 is arranged at the upper end of the height-adjustable column 22. The seat 4 can be inclined forwards and backwards about an inclination axis 26.

[0058] The restraining device 5 for the surgeon comprises a harness system 6 and a traction device 9. In the illustrated embodiment example, the harness system comprises a first shoulder strap 7 and a second shoulder strap 8. The harness system 6 is connected to the traction device 9 at the suspension points S1, S2, S3 and S4 (attached to it).

[0059] In the embodiment example illustrated in FIG. 1, a support unit 13 defines the distance D12 between the first upper suspension point S1 and the second upper suspension point S2 and bridges this distance D12.

[0060] The support unit 13 also determines the distance D23 between the second lower suspension point S3 and the first lower suspension point S4. The support unit 13 can, for example, be configured as a (rigid, dimensionally stable) frame. The support unit 13 can also be configured as a closed plate or a plate provided with openings or as a skeletonized plate, in each case made of metal or plastic.

[0061] The support unit 13 is connected to an abutment 15 via a traction element 14. The support unit 13 also has a height-adjustable connecting device 16, with which it is possible to variably define a connection point V between the traction element 14 and the support unit 13. This allows the support unit 13 and the connection point V to be adapted to the height of the surgeon. The abutment 15 comprises a height-adjustable deflection roller 20 and further deflection rollers 27, with which the traction element 14 is guided to a winch which has an electric geared motor 21, which can be designed to be self-locking (self-braking), for example.

[0062] FIG. 2 illustrates an alternative embodiment example of system 1 according to the present disclosure. In FIG. 2, a first support element 11 bridges the distance D12 between the upper suspension points S1 and S2. A second support element 12 bridges the distance D34 between the lower suspension points S3 and S4. In this example, the first and second support elements 11, 12 do not form a single-piece support unit 13. The first support element 11 is mechanically connected to a first abutment 15 via a first traction element 14. The second support element 12 is mechanically connected to a second abutment 19 via a second traction element 17. In this example, the abutments 15, 19 each have a height-adjustable deflection roller, at least one further (non-height-adjustable) deflection roller 27 and an electric geared motor. The abutments can be constructed identically.

[0063] FIG. 3a shows an exemplary support unit 13. The support unit 13 has a first upper suspension point S1, a second upper suspension point S2, a first lower suspension point S4 and a second lower suspension point S3.

[0064] The support unit 13 comprises a first support element 11 and a second support element 12. The first support element 11 is configured as a star-shaped rigid element, which has three legs. Two upper legs of the first support element 11 lead to the first upper suspension points S1 and S2.

[0065] The second support element 12 is also designed as a three-legged star, with the lower two legs of the second support element 12 leading to the lower suspension points S3 and S4.

[0066] The third leg of the first support element 11 and the second support element 12 meet in the middle and are connected in such a way that they form a single-piece (monolithic) unit.

[0067] The support unit 13 bridges the distance D12 between the first upper suspension point S1 and the second upper suspension point S2, the distance D23 between the second upper suspension point S2 and the second lower suspension point S3, the distance D34 between the second lower suspension point S3 and the first lower suspension point S4, and the distance D14 between the first upper suspension point S1 and the first lower suspension point S4. The support unit 13 is designed as a rigid frame. Furthermore, the support unit 13 has a height-adjustable connecting device 16, to which a traction element 14 can be connected.

[0068] FIG. 3b shows a further example of a support unit 13. In this embodiment example, the support unit 13 is at least essentially X-shaped so that the distances D12, D23, D34 and D14 are also bridged by the support unit 13. In this example, the connecting device 16 is arranged at the intersection of the X-shaped support unit 13.

[0069] FIG. 3c shows an example of a support unit in which the support unit 13 is at least essentially H-shaped. In this embodiment example, the support unit 13 also bridges the distances D12, D23, D34 and D14. In addition, the support unit 13 has a connecting device 16, which is preferably attached in a central area of the H-shaped support unit 13.

[0070] FIG. 3d shows a further example of the support unit 13. In this example, the first support element 11 has at least essentially a T-shape and the second support element 12 has a three-legged star shape. In this embodiment example, the first support element 11 and the second support element 12 are connected to form a support unit 13. The connecting device 16 is attached to the support unit 13, preferably in an area in which the legs of the support elements 11, 12 are connected to one another. The connecting device 16 can be height-adjustable.

[0071] FIG. 3e shows a support unit 13 in which the first support element 11 is designed as a three-legged star and the second support element 12 is designed as a T-shaped element. In this example too, as in the example in FIG. 3d, a height-adjustable connecting device 16 is attached to the support unit 13.

[0072] FIG. 3f illustrates an example of the support unit 13, in which the support unit 13 is designed as a plate. In this example, the height-adjustable connecting device 16 is mounted in a central area of the plate. It is also possible, as already described above, to use a skeletonized plate as support unit 13.

[0073] In the examples of the support unit 13 as illustrated in FIGS. 3a to 3f, the distances between the suspension points S1, S2, S3 and S4 of the support unit 13 are fixed. The distances also remain at least substantially the same during operation, i.e. under tensile load of the harness system 6.

[0074] FIG. 3g shows an example of an alternative to the support unit 13. In this example, the upper suspension points S1 and S2 are bridged by a first support element 11. Furthermore, a second support element 12 bridges the lower suspension points S3 and S4. In this example, a connecting device 16 is attached to the first support element 11 and to the second support element.

[0075] The first support element 11 and the second support element 12 are not connected in this embodiment example. In this embodiment example, a first traction element 14 is associated with the first support element 11 and is (mechanically) connected to the connecting device 16 of the first support element 11. A second traction element 17 is associated with the second support element 12, which is (mechanically) connected to the connecting device 16 of the second support element 12. In this embodiment, the support elements 11 and 12 can be connected to separate abutments 15 and 19 via the traction elements 14 and 17.

[0076] FIG. 4a shows an embodiment example of the harness system 6. In this embodiment example, the harness system 6 comprises a first shoulder strap 7, a second shoulder strap 8 and a waist strap 10. The first shoulder strap 7 is attached to the first upper suspension point S1 and the first lower suspension point S4. The second shoulder strap 8 is attached to the second upper suspension point S2 and the second lower suspension point S3. The waist strap 10 is attached to the lower suspension points S3 and S4. In FIG. 4a, a chest strap 31 is attached with one end to the first shoulder strap 7 and with the other end to the second shoulder strap 8. In this example, the chest strap 31 mechanically connects the shoulder straps 7, 8. The points at which the chest strap 31 is connected to the shoulder straps 7, 8 can be continuously displaced and locked along the shoulder straps 7, 8 (as illustrated by the double arrows in FIG. 4a). In addition, the chest strap 31 is preferably continuously adjustable in length. When the harness 10 is put on by a surgeon, the chest strap 31 can be adjusted so that it extends at the surgeon's chest height. As a result, the shoulder straps 7, 8 are held in positions that are comfortable for the surgeon, so that the surgeon does not experience any incisions, lymph congestion and/or discomfort in his arms.

[0077] FIG. 4b shows a further embodiment example of the harness system 6. In this embodiment example, the first shoulder strap 7 and the second shoulder strap 8 are not attached to the lower suspension straps, but to the waist strap 10. The waist strap 10 is in turn attached to the lower suspension points S3 and S4.

[0078] FIG. 5 shows an embodiment example of the system according to the present disclosure. The system 1 comprises a base frame 3, on which a height-adjustable column 22 is arranged, which is configured to be pivotable via a joint device 23. The joint device 23 defines a pivot axis 24.

[0079] An inclination device 28 is arranged at the upper end of the column 22, with which the seat 22 can be inclined forwards or backwards. The inclination device 28 can be actuated by the surgeon manually and/or by motor, for example via an operating device.

[0080] Furthermore, an abutment column 29 is attached (mounted) to the column 22. The abutment column 29 is firmly connected to the column 22 of the operating chair 2, so that it pivots with the operating chair when the operating chair 2 is pivoted sideways.

[0081] Deflection rollers 27 are arranged at the upper end of the abutment column 29 with which the traction element 14 is deflected from the front side of the abutment column 29 to the rear side of the abutment column 29. The traction element 14 is, thus, guided to a winch with an electric geared motor 21, which can be designed to be self-locking.

[0082] A height-adjustable guide roller 20 is arranged at the front of the abutment column 29. The traction element 14 is connected to a support element 13, which a surgeon can carry on his or her back. The restraining harnesses 7, 8 of the harness system 6 are connected to the support unit 13 at the suspension points S1 to S4.

[0083] In the present embodiment example, the first shoulder strap 7, which is connected to the first upper suspension point S1 and the second lower suspension point S4, is illustrated. Arm supports 30 are attached to the abutment column 29, which extend laterally next to the surgeon above the operating chair 2. An operating unit for the system 1 can be accommodated in the arm supports 30, for example.

[0084] FIG. 6 illustrates a further embodiment example of the system 1. In this embodiment example, the abutment column 29 is rigidly connected to the base frame 3, for example with the column 22 can be inclined laterally as described above. In this case, the upper body of the surgeon is suspended in a pivoting manner by the traction element and can follow the lateral inclination. However, it is also possible to provide the support column 29 with its own inclination device so that the support column can be inclined independently of the column 22. A motorized adjusting device can be assigned to the inclination device. This can be designed with one or two axes in order to be able to tilt the abutment column forwards/backwards and/or sideways. In this way the operating chair 2 can be pivoted sideways manually or by motor independently of the abutment column 29.

[0085] The system 1 described in this respect for supporting the surgeon works as follows:

[0086] To perform an operation, the system 1 is moved to the operating table in a controlled manner by means of a controlled unit not shown further, wherein the control unit may, for example, have at least one joystick and further control buttons or other operating elements. The surgeon puts on the harness system 6 by slipping the at least two shoulder straps 7, 8 over his shoulders. If the harness system 6 has a waist strap 10, the surgeon puts on the waist strap 10 which, when put on, preferably extends in the lower abdominal region of the surgeon, preferably below his diaphragm or his ribcage. The surgeon can wear the harness system over his surgical gown as well as over or under additional surgical clothing, such as an X-ray apron. The surgeon is then dressed in sterile clothing, for example a sterile surgical gown. The surgeon can now enter the operating room, enter system 1 and be connected to the traction element 14 at his back by means of the connection unit 16 (the shackle or the carabiner hook), for example through a slit in the sterile surgical gown.

[0087] If the restraining device 5 has a support unit 13 as shown in FIG. 1, 3a to 3f, 4a, 4b, 5 or 6, the support unit 13 rests against the back of the surgeon in the applied state, so that the upper suspension points S1, S2 are arranged in the upper back region of the surgeon above the shoulders. The lower suspension points S3, S4 are arranged in the lower back area, for example in the lumbar vertebrae area of the surgeon. The distance D14, D23 between the upper suspension points S1, S2 and the lower suspension points S3, S4 can be variably adapted to the length of the surgeon's back.

[0088] If the restraining device 5 has two unconnected support elements 11, 12, the first support element 11 rests on the upper back area of the surgeon when it is in the applied state and the second support element 12 rests on the lower back region of the surgeon.

[0089] The surgeon then takes a seat on the seat 4 of the operating chair 2. The support unit 13 can be connected to the abutment 15 via the traction element 14 before the surgeon puts on the harness system 6. The harness system 6 can also be applied by the surgeon first. The support unit 13 is then connected to the traction element 14 via the connection unit 16. The traction element 14 is not under tensile stress when the surgeon applies the harness system 6 and/or when the support unit 13 is connected to the traction element 14 via the connecting device 16. The point on the connecting device 16 can now be adapted to the size of the surgeon to provide comfortable restraint for the surgeon. For example, this point can be located in the area between the shoulder blades of the surgeon.

[0090] The surgeon can now use the control unit to shorten the length of the traction element 14 so that he can lean forward into the harness system 6 and is held back by the traction device 9 at a desired angle of inclination of his upper body. The traction element 14 and the harness system 6 are now under tensile load. By changing the length of the traction element 14, the surgeon can also freely choose the angle of inclination at which he is supported by the traction device 9 during the operation. The surgeon can also move his upper body laterally, whereby the connection point V, at which the traction element 14 is connected to the support unit 13 via the connection unit 16, describes an arc of a circle with the abutment column 29 as the center when the upper body moves laterally.

[0091] In addition, the surgeon can use the control unit to set a desired height of the operating chair 2, a desired lateral inclination of the operating chair 2 and a desired inclination of the seat 4. If a lateral angle of inclination of the abutment column 29 can be set independently of the angle of inclination of the operating chair 2, i.e. the abutment column 29 is not firmly fixed to the column 22 of the operating chair 2, the surgeon can set the angle of inclination of the abutment column 29 independently.

[0092] Furthermore, a second control unit can be provided with which it is possible for a further person to control the system 1, for example by the person making the desired settings on the operating chair 2 and/or traction device 9 at the instruction of the surgeon.

[0093] The system according to the present disclosure is used to assist a surgeon. It has an operating chair 2 and a restraining device 5 for the surgeon. The restraining device 5 has a harness system 6 which comprises at least a first and a second restraining harness 7, 8 which are connected to at least a first and a second spaced-apart tension point S1, S2, S3, S4 of a traction device 9, wherein the traction device 9 is configured to determine the distance between the suspension points S1, S2, S3, S4 and in any case to resist a change in distance. The system according to the present disclosure improves the wearing comfort of the restraining device 5 for the surgeon, since it prevents the restraining harnesses 7, 8 of the harness system 6 from constricting under tensile load, which can lead to unpleasant and undesirable pressure sensations in the upper body area of the surgeon.
