Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to an operating table on which a patient is placed on the upper table for surgery, and particularly to an operating table suitable as a surgical operating table.

B. Conventional technology Conventionally, operating tables have come in various shapes.
The lower part has a base part, and this base part stabilizes the operating table, that is, its column or table part. In recent years, this base has become taller and has built-in various devices such as a power supply section, a control section, and a drive source section for operating the operating table. In particular, in the case of an electric operating table, electrical components are built into the base, and in the case of a hydraulic operating table, a hydraulic pressure generator, that is, a hydraulic pump is built into the base.

FIG. 4 is a schematic cross-sectional view of the structure of the lower part of the operating table, where B indicates a base portion, C indicates a column portion, and R indicates wheels for movement. The base portion B has a rust-preventing stainless steel plate S attached to the upper surface portion of a frame F forming the base body so as to cover the entire base. This frame frame F is configured to form a storage recess N for housing various devices D therein. A cover K is placed in the opening above this built-in part.

By the way, especially on a surgical operating table, a large amount of physiological saline is used in surgical operations, and this physiological saline is dripped from the upper part to the base part.

C. Problems to be solved by the invention The problem with conventional operating tables is that the physiological saline dripped onto the base can leak into the built-in parts N of various devices D through the gap between the cover K and the stainless steel plate S of the base. This is the point where they can get in and cause rust and failure of these devices. The cover K needs to be removed for inspection of the various devices D and to facilitate installation. Although the cover K is fixed to the upper surface of the stainless steel plate S, attempts have been made to interpose a gasket between the cover K and the stainless steel plate S in order to solve the above-mentioned drawbacks. However, it is still impossible to completely prevent the intrusion of physiological saline. Furthermore, it is impossible to prevent salt water from entering through the gap between the cover fixing bolt and the cover.

D Means for Solving Problems According to the present invention, an extending portion extending upward is formed around the entire periphery of the base opening in the device built-in portion, and the cover is attached to the outer periphery side of the extending portion. Configure to surround. Further, a locking mechanism for removably locking the cover to the base is provided between the lower surface of the cover and the base side.

E Effect: The formation of the extending portion of the base prevents liquid dripping onto the base from entering the built-in portion. Moreover, since the cover is locked to the base portion by the locking mechanism, it does not move.

F Example The embodiment shown in the figure will be described below.

FIG. 1 is a perspective view showing the entire operating table according to the present invention, and T is a table section on which a patient is placed.

The cover 3 installed on the lower base part B is the main part of the present invention, and its details are shown in FIG. FIG. 2 shows a longitudinal section of the cover 3 cut not at the center of the base portion B but at a position eccentric from the center.
In the figure, 1 is a base frame of the base part B, and 2 is a stainless steel plate attached to the upper surface and sides thereof.

The base frame 1 has a space N for housing various devices D.
In order to form a predetermined portion, a recess 1N is formed. A wheel R is attached to the left direction. 6
is a fixture for fixing the wheel R to the base frame 1.

By the way, in the present invention, an extending portion 2F that extends slightly upward is formed around the entire periphery of the opening of the base in the upper direction of the space N for housing the device D, that is, the opening of the stainless steel plate 2. has been done. This extending portion 2F prevents the liquid dripping onto the upper surface 2 of the base portion B from falling into the space N. The cover 3 is installed on the base portion so as to surround the outer peripheral side of the extension portion 2F.

The extending portion 2F extends not only above the space where the device is built-in but also above the wheel R, and therefore the cover 3 also surrounds and covers not only the device D but also the fixture 6 of the wheel R. It's becoming like that. cover 3
The fixing tool 6 is attached to the flange frame 3C attached to the lower surface of the
The fixing device 6 is designed to surround the fixing device 6, and prevent wiring and the like located in the space above the wheel R and below the cover 3 from touching the fixing device 6.

Further, in the present invention, means for locking the cover 3 to the base portion is provided. That is, the base frame 1 is formed with a cylindrical convex portion 1P. A locking pin 5 is implanted on a plate 4 attached above it. On the other hand, a locking frame 3F having a U-shaped cross section is attached to the lower surface of the cover 3. This frame 3F has a hole 3H at a position facing the locking pin 5.
is drilled through the locking pin 5 as shown in the figure, and a leaf spring 3 is inserted into the penetrating portion of the locking pin 5.
B is attached so as to be elastically loaded on the locking pin 5. The locking pin 5 is designed to be able to pass through and escape against the elasticity of the leaf spring 3B. However, as shown in the figure, when the cover 3 is penetrated, the elasticity of the leaf spring 3B maintains that state, so the cover 3 is held in that position without moving relative to the base, and covers the built-in device D. become.

The present invention can be applied not only to surgical operating tables but also to other operating tables. The shape of the cover is also not limited to only a rectangle. In the case of a surgical table to which a stainless steel plate is not attached (affixed), an extending portion is formed around the entire opening of the base frame. Further, the extending portion may be formed not by bending the member but by attaching another member (by welding and adhering, etc.).

G. Effects According to the present invention, the liquid dripped onto the base part does not enter the built-in part of the equipment, and the failure of the equipment due to rust is eliminated, and a safe and sanitary operating table can be obtained.
Furthermore, since the cover can be locked even if there is a slight gap, it is safe and the equipment is sufficiently protected. Since the cover is not installed with bolts or the like, it is easy to attach and detach, which is advantageous in terms of maintenance. Moreover, the cover is simple and has a simple appearance, improving the overall appearance of the operating table.
