DETAILED DESCRIPTION AND INDUSTRIAL APPLICABILITY

[0048] In FIGS. 1 and 2, in each case, a diagrammatic perspective representation of a first embodiment of an operating table device 10 for securing accessories to rails of an operating table is shown. The device 10 may be, for example, a bracket.

[0049] The device 10 may comprise a first securing assembly (e.g., first securing unit 12) for securing the device 10 to the rails of the operating table. This first securing unit 12 may comprise a first hook 14, which may be designed to be part of a base body 16 of the device 10. This hook 14 can be hung over the upper side of the rail of the operating table, so that the rail is accommodated in the recess 18.

[0050] Furthermore, the first fastening unit 12 may comprise an additional hook 20, which can be adjusted manually via a lever 22. As soon as the device 10 has been put from above onto the rail, the lever 22 may be moved out of the position shown in FIG. 2 in the direction of the arrow P1, as a result of which the second hook 20 may be moved in the direction of the arrow P1, so that it encloses the rail of the operating table from below and thus may establish a clamping connection. As a result, a reliable securing on an operating table rail may be achieved. For example, an axial sliding on the rail may also be substantially prevented. The lever 22 may comprise a snap-in element, and which can engage in a complementary detent 24 in such a manner that the lever 22 and thus the second hook 20 may remain in the desired position.

[0051] On the side of the base body 16 facing away from the first securing unit 12, a second securing assembly (e.g., second securing unit 30) for securing an elongated member of an accessory (e.g., a rod of an accessory) to the device 10 and thus to the operating table may be provided. This accessory can be, for example, a body support, an arm support and/or an anesthesia bow. These accessories have in common that they may comprise a rod which is to be secured extending vertically to the operating table in a height adjustable manner via the device 10. As described for example below, this may be made possible for a relatively large number of different predetermined profiles of the rod.

[0052] The second securing unit 30 may have an aperture (e.g., a hole, through-hole, or passage hole 40), through which the rods of the accessories to be attached (e.g., secured) to the device 10 may be led. The hole 40 may be designed for example in such a manner that rods with a square profile, rods with a rectangular (non-square) profile, and also rods with a round profile with or without planar surface, rods with a hexagonal profile and also rods with an octagonal profile, for example in each case between a minimum and a maximum size, can be led.

[0053] In this regard, the hole 40 may have, for example, on the side facing the clamping assembly (e.g., tommy screw 36), a flat surface 42 as side wall, and a V-shaped notch 44 may be provided in the middle.

[0054] The second securing unit 30 may comprise a hole 52 which may extend up to and into the hole 40. In the hole 52, a threading may be provided, in which the tensioning screw engages. By turning the lever 54 of the tensioning screw 36, the latter can be moved in axial direction of the hole 52 into the hole 40 and out of the latter, as a result of which the accommodated rods, as will be described below, may be clamped in.

[0055] The hole 40 may be designed in such a manner that the longitudinal axis thereof, in the case of installation of the device 10 according to plan, may be vertically oriented on a horizontally extending rail of the operating table.

[0056] In FIG. 3, an additional diagrammatic perspective representation of the device 10 is shown, wherein, here, the view is directed into the hole 40. The hole 40 may be shaped in such a manner that rods with a round profile, rods with a rectangular, non-square profile, rods with a square profile, rods with a hexagonal profile and also rods with an octagonal profile can be clamped suitable (for example, reliably) within the hole. The aperture (e.g., hole 40) may have a cross section having a polygonal shape, the polygonal shape being formed from at least two superimposed shapes, each of the at least two superimposed shapes having straight sides (for example, as shown in FIGS. 3-12). For example, the cross section of the hole 40 can be selected in such a manner that some or all the above-mentioned profile types may abut, on the facing side of the hole 40, against the wall of the hole either with flat contact or at least along two contact lines, so that both slipping and also twisting may be substantially prevented. The corresponding contacting can be seen for example in FIGS. 5 to 10 for the different profile types mentioned above. It is also contemplated that the cross section of the aperture (e.g., hole 40) may have one or more sides that are not straight (e.g., curved or elliptical).

[0057] In FIG. 4, an additional diagrammatic perspective representation of the device 10 according to FIGS. 1 to 3 is shown, wherein, for explaining the shaping of the hole 40, exemplary geometric shapes in the hole 40 are indicated by dotted lines or broken-dotted lines.

[0058] The cross section of the hole 40 may result from the superposition of a square 72 as well as two rectangles 74, 76. The rectangles may be shaped substantially identically and may be arranged rotated with respect to one another by 90° (e.g., by about 90°). The square 72 may be arranged rotated by 45° (e.g., by about 45°) relative to the two rectangles, wherein the center of the square 72 and the centers of the rectangles 74, 76 may coincide at a point. The diagonal lengths (e.g., the straight distance length from one corner of the square to the opposite corner of the square) of the square 72 may be longer than the long sides of the rectangles 74, 76, as a result of which the square may project on the short sides of the rectangle beyond said rectangles, so that they result in V-shaped notches in the contour of the hole 40. For example, viewed overall, the contour of the hole 40 may be formed on some parts by the square 72, on some parts by the rectangle 74, and on some parts by the rectangle 76.

[0059] As explained below in connection with FIGS. 5 to 10, via this shaping (e.g., exemplary special shaping) of the hole 40, some or all the common profile types can be suitably clamped via the device 10 and thus attached (e.g., secured) to the operating table.

[0060] In FIG. 5, the accommodation of elongated member 100 (e.g., a rod) with a round profile is shown. This rod may abut against the wall of the hole 40 on the side facing the tensioning screw 36 via two contact lines and may thus be reliably fixed.

[0061] FIG. 6 shows a top view onto the device 10 according to FIGS. 1 to 4, wherein a rod 102 with a rectangular profile may be clamped in. The rod 102 may lie flat against the subsection of the periphery of the hole 40 which may be formed by the rectangle 76, so that the rod 102 can also be suitably fixed (e.g., reliably fixed).

[0062] FIG. 7 shows a top view onto the device 10 according to FIGS. 1 to 4, wherein a rod 104 with a rectangular profile may be accommodated. However, in comparison to the exemplary rod 102 in FIG. 6, this rod 104 may be arranged rotated by 90°. This rod may be pressed via the tensioning screw 36 against the surfaces formed by the rectangle 74, so that the rod 104 can also be clamped in a slide-proof and twist-proof manner

[0063] In FIG. 8, a top view onto the device 10 is shown, wherein a rod 106 with a square profile may be accommodated in the hole 40. Here, the edges of the square profile may be accommodated in the V-shaped notches formed by the square 72, so that a suitable hold (e.g., reliable hold) may be provided.

[0064] In FIG. 9, an additional top view onto the device 10 is shown, wherein a rod 108 with an octagonal profile may be accommodated.

[0065] FIG. 10 shows a top view onto the device 10 according to FIGS. 1 to 4, wherein a rod 110 with a hexagonal profile 104 may be accommodated in the hole and suitably clamped in (e.g., clamped in reliably).

[0066] In FIG. 11, a diagrammatic representation of a device 80 for securing an accessory to an operating table according to a second embodiment is shown. In this second embodiment, the hole 40 may be shaped differently, for example including the superposition of the square 72 and the rectangle 74.

[0067] In this shaping as well, as before, a relatively large number of different profile types, but for example not as many profile types as in the first embodiment, can be accommodated. For example, no rectangular profiles that are arranged in accordance with the rod 102 in FIG. 6 can be accommodated.

[0068] In FIG. 12, a top view onto a device 90 for securing an accessory to an operating table according to a third embodiment is shown. In this third embodiment, the hole 40 may be shaped in such a manner that the cross section thereof may result from the superposition of the square 72 and the rectangle 76. In at least some exemplary embodiments, substantially no rods that are arranged for example in accordance with the rod 104 according to FIG. 7 can be accommodated.

[0069] Overall, via the above-described device 10, rods 100 to 108 with many different predetermined profiles can be secured via the device 10 to the operating table. Furthermore, unsuitable rods may be substantially prevented from being introduced in the respective set operating state, which may provide suitable securing (e.g., reliable securing).

[0070] Thus, the user may use for example a single device 10 which is used for a relatively large number of accessories. In addition, the device 10 may not be secured permanently via a bonding connection to the respective accessories.

[0071] In at least some exemplary embodiments, the device 10 can remain on the operating table when the patient is transferred to a different bed, because the device 10 may not project beyond the operating table and thus may not impede the transfer.

[0072] In addition, via the device 10, the handling may be overall simplified, because all the accessories can be fixed by substantially the same handholds and are not adjusted by the user in each case depending on individual securing devices. In addition, unlike in the case of radial setting clamps, a tilting away of the device 10, when the securing is released, may be substantially prevented.

[0073] Furthermore, the square profiles may be clamped on the edges, whereby, unlike in the case of flat clamping, a deformation may be substantially avoided in the case of hollow profiles.

[0074] It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed method and apparatus. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice of the disclosed method and apparatus. It is intended that the specification and the disclosed examples be considered as exemplary only, with a true scope being indicated by the following claims.
