This application claims the benefit of and priority to German Patent Application Serial No. 102016217803.2, filed on Sep. 16, 2016, which is incorporated herein by this reference in its entirety.
The invention relates to a patient supporting plate with an accessory part, more particularly with an accessory part which is mounted to the patient supporting plate in the region of a hinge.
Patient supporting plates, on which fastening rails, to which medical apparatuses or tools can be fastened, are mounted laterally and/or to the end faces as accessory parts, are known from the prior art. The fastening rails are usually provided with through holes with countersinks, the rails being bolted to a frame of the patient supporting plate through said through holes. However, these processes produce gaps between screw heads and the countersinks, wherein said gap deteriorates the hygienic conditions. Therefore, the through holes with countersinks are sealed with covering caps on a case-by-case basis. This, however, involves additional expenditure and presents the risk of the covering caps dropping off.
Document U.S. Pat. No. 6,678,908 B2 discloses additional supporting elements for patient supporting plates in order to widen the supporting surface for overweight patients. These additional supporting elements encompass around a patient supporting surface of the patient supporting plate and can be pinned to the lateral fastening rails of the patient supporting plate. Lateral fastening rails for attaching the medical apparatuses or tools are likewise provided on said additional supporting elements. Said lateral fastening rails are fastened to the additional supporting elements from the inside by means of fastening screws, thereby permitting a smooth homogeneous surface on the outside of the fastening rails, which prevents hygienic conditions being deteriorated and eliminating the need for additional cover caps.
However, such fastening of the lateral fastening rails in the region of hinges between plate segments of the patient supporting plate is highly complex due to the structural design of the hinges. Moreover, the hinge needs to be dismantled for retrospective disassembly of the fastening rails.
Therefore, the invention addresses the problem of improving a patient supporting plate in such a manner that the aforementioned problems are solved, and the structure of the hinges on the patient supporting plate are optimized.
The problem is solved by a patient supporting plate according to claim 1. Advantageous developments are the subject matter of the dependent claims.
The invention will now be elucidated in terms of an embodiment and by making reference to the attached drawings.
More particularly:
Moreover, a fastening rail 7 is attached to the hinge 5 as an accessory part.
Moreover, the hinge 5 is shown with the fastening rail 7 and provided with a drive device 10. The drive device 10 has a drive element 11, which is described later on.
The drive element 11 can be fastened arranged in the direction of the swivel axis 6 on the coupling element 8. For this purpose, it is provided with a first through opening 14. The drive element 11 is not necessarily arranged on the swivel axis 6. A position of the first through opening 14 is selected such that it is also accessible when the hinge 5 has been installed in the operating table 1. The coupling element 8 is provided with a second through opening 15. A washer 21 shown in
Moreover, the fastening rail 7 is attached to the hinge 5 as described below. The fastening rail 7 is provided with a receptacle 16. As shown here, the receptacle 16 does not pass continuously through the fastening rail, and so the fastening rail has a surface, facing away the drive element 11, which is smooth and homogeneous.
As shown in
In order to mount the hinge 5, the first fastening element 17 is inserted through the first through opening 14 of the drive element 11 and the second through opening 15 of the coupling element 8 from the side of the drive element 11 located opposite the coupling element 8 is inserted through the first through opening 14 of the drive element 11 and the second through opening 15 of the coupling element 8 and, in the receptacle 16, this having a nut thread in this instance, it is connected, i.e. in this case bolted, to the detachable fastening rail 7. This allows the fastening rail 7 to be simply removed, for a replacement for instance, without having to completely dismantle the hinge 5. Alternatively, multiple first fastening elements 17 can be used. Insofar as only one fastening element 17 is used, it would seem appropriate to connect the fastening rail to the coupling element 8 by means of a positive connection.
A positive connection between the coupling element 8 and a further first form-fitting element 18 and between the drive element 11 and a further second form-fitting element 19 is also possible. In the interest of clarity, this is not shown here graphically. Hence, the positive connection is provided either between the drive element 11 and the coupling element 8 and/or between the drive element 11 and the further coupling element 13. In addition to the first fastening element 17 for a positive connection with the drive element 11, the form-fitting elements 18, 19 are provided with the coupling element 8 or with the further coupling element 13. These form-fitting connections can be designed with practically no backlash and are able to transmit a high torque.
The first form-fitting elements 18 are formed at the coupling element 8 or at the further coupling element 13 by means of an elevation in the direction of the swivel axis 6. Each of the second form-fitting elements 19 are formed by means of an indentation on the drive element 11. The first and second form-fitting elements 18, 19 are complementary and designed to transmit a high torque. In this case, the form-fitting elements 18, 19 have the contour of a hexagon in the direction of the swivel axis 6. Alternatively, the indentation can also be provided in the coupling element 8 and in the further coupling element 13, and the elevation can be provided at the drive element 11. Alternatively, the contour of the form-fitting elements 18, 19 can have a different form, pentagonal or oval for example, as long as a high torque can be transmitted.
The spacer 20 is fastened to the fastening rail 7 or integrated therein.
Alternatively, the spacer 20 can also be fastened, as shown in
All the features shown in the description, the claims below and the drawings can be essential to the invention both individually and also in any combination with one another.
