Description

[Detailed description of the invention] The present invention relates to surgical operating tables.

Traditionally, surgical operations include general surgery and orthopedic surgery for treating fractures, etc., but there is no one that allows both operations to be performed on a single operating table.

General surgery is an operation that is usually performed by a surgeon using a scalpel, etc., and the patient needs to be placed on the operating table at a relatively low position (about 750 mm to 1000 mm from the floor). During the surgery, the patient is placed on the operating table at a relatively high position (approximately 950 mm to 1,300 mm above the floor) because operations such as driving an intramedullary nail into the fracture site, performing X-ray fluoroscopic imaging, applying a cast, and traction of the affected area are performed. However, for this purpose, no operating table has been realized in which the waist plate, headrest, etc. can be changed between a low position and a high position.

Simply making the head rest and lumbar plate vertically movable relative to the operating table base frame does not create an operating table that can perform both of these surgeries. It was necessary to install a table and an orthopedic operating table. This was not only economically disadvantageous, but also posed various problems, including the need for space.

The present invention aims to provide an operating table that eliminates these conventional drawbacks.

The operating table of the present invention is provided with a means for selectively fixing upper body support devices such as a headrest, a back plate, and a waist plate in a high position and a low position, and in particular, with regard to the leg plate, the upper body support devices such as a headrest, a back plate, and a waist plate are fixed in a high position and a low position. The operating table base frame can be moved in the longitudinal direction of the operating table, making it possible to install the groin support at a high position, and the traction mechanism is removably fixed to the operating table base frame. It is characterized by having a means for installing it.

Furthermore, while a leg plate is required during anesthesia, a leg plate is not required during traction, so another feature is that the groin support and leg plate can be installed separately and detachably.

The illustrated embodiment will be described below.

In the figure, reference numeral 1 denotes a column of an operating table, to which a column 2 is attached so as to be able to move up and down slightly, and a base frame 3 is placed on this column 2. 4 is a headrest, 5 is a back plate, and 6 is a waist plate, which are attached to the base frame 3 and are supports for supporting the upper body of the patient K. 7 is a main leg plate, 8 is an auxiliary leg plate, and 9 is a connector for connecting both leg plates 7 and 8.

Head rest 4, back plate 5, waist plate 6, leg plates 7, 8
constitutes the base of the operating table on which the patient K is placed. These are arranged on one horizontal plane and the base frame 3
can be attached to. Patient K is placed on this horizontal surface, which is at a height h (lower position) than the floor surface.
In FIG. 4, it is at a height H (higher position) than the floor surface. The position shown in Figure 2 is for general surgery.
The position shown in Figure 4 is for orthopedic surgery. As mentioned above, the height of each operating table is h = 750 to 1000 mm, H
=950-1300mm.

In the case of general surgery, the base frame 3 of the operating table itself is determined in consideration of the height of the operating table for general surgery, as shown in Figure 2. By installing it on the base frame 3 at a position close to the base frame 3, a low-position general surgery operating table is realized.

In the case of an operating table for general surgery, both the main leg plate 7 and the secondary leg plate 8 are required, but in orthopedic surgery, especially when performing post-anesthesia traction treatment, Figs. 3 and 4 are used.
As shown in the figure, the leg plates 7, 8 are removed. This is because the leg plates 7 and 8 interfere with traction treatment.

In FIGS. 3 and 4, members indicated by numerals 15 to 17 include a headrest 4, a back plate 5, a waist plate 6,
This is for fixing the coccygeal support piece 10' integrated with the groin support 10 to the base frame 3 at a high position.

Hereinafter, a configuration in which each plate is selectively fixed and installed at a low position or a high position will be explained with reference to FIGS. 5 to 8.

The head rest 4 and the back plate 5 are integrated by a connecting tool 4', and the back plate 5 is installed directly or indirectly on the base frame 3, but there are connecting screws 5' on the underside of the back plate 5. Either the mounting hole 3H formed in the base frame 3 is screwed into the mounting hole 3H, or the mounting hole 15H of the support rod 15 is threaded into the mounting hole 15H. The support rod 15 has its lower threaded portion 1
5' can be screwed into the mounting hole 3H of the base frame 3 and can be attached or detached.

Reference numeral 16 denotes a support rod for the waist board 6, which is moved up and down by a rotational drive source (not shown) in the column 2.
A wainscot 6 fixedly installed on the top can be set at a high position and a low position. If the back plate 5 and the head rest 4 are integrally fixed to the vertically movable support rod 16, the support for supporting the upper body of the patient K can be easily and automatically set to a high position or a low position. It can be installed permanently.

As is clear from FIGS. 1 and 2, in general surgery, the leg plates 7, 8 are placed close to the lumbar plate 6 so that general surgery can be performed safely. However, in orthopedic surgery, the leg plate 7 is simply used to temporarily support the patient K when being anesthetized, and for this reason, the leg plate 7 is retracted from the lumbar plate 6 and fixed so as to be suitable for temporary support. will be installed. Its retreat direction coincides with the longitudinal direction of the operating table.

7 and 8 show an orthopedic operating table, in particular an operating table for temporarily supporting a patient K in order to anesthetize him as described above.

As shown in FIG. 5, the leg plate 7 is integrated with a mounting frame 19 and is removably fixed to the base frame 3 via a mounting screw 19' provided at the tip of the mounting frame 19. That is, as shown in detail in FIG. 9, the base frame 3 is provided with branch arms 3R on both sides, and a screw nut N for fixing the leg plate and a positioning pin P are attached to the tips of the branches. There is. When the mounting screw 19' of the mounting frame 19 is directly threaded into this threaded nut N, the leg plate 7 is installed close to the waist plate 6 and the first
As shown in Fig. 2, it is used for general surgery.

On the other hand, if the L-shaped arm 18 is interposed, the third
As shown in Fig. 4, it is used for orthopedic surgery, and in this case, as shown in Fig. 5, the screw 18' at the lower part of the L-shaped arm 18 corresponds to the mounting screw 19' and is screwed into the nut N. . The nut N' and pin P' at the upper part of the L-shaped arm 18 correspond to the nut N and pin P, and indirectly fix and install the leg plate 7 to the base frame 3. This L-shaped arm 18 allows the leg plate 7 to be retracted from the waist plate 6 in the longitudinal direction of the operating table in the high position. 20 is a fixing screw.

In order to install the table in a high position, that is, as an orthopedic operating table, a limb traction mechanism must be added, and at the same time, a groin support must be installed for traction.

The retraction of the leg plate 7 from the waist plate 6 is to interpose this groin support between the two plates, but the installation of this traction mechanism and groin support is done by attaching and detaching it to the base frame 3 as shown in Figs. 6 and 9. This is done by means of a main support arm 11 which can be mounted.

The main support arm 11 has its mounting base 11K fixedly attached to a mounting shaft (not shown) of the base frame 3 in a removable manner. A support cylinder 12 with an adjustment mechanism is attached to the tip of the main support arm 11, and a groin support 10 and a coccygeal support piece 10' are supported above the support cylinder 12 via a support rod 17. Further, a sub-support arm 13 is attached to the support cylinder 12, and a traction mechanism 14 is installed at the tip of the sub-support arm 13.

When a high-position operating table, that is, an orthopedic operating table is formed with the above-described configuration, a patient is placed and supported on the table, and anesthesia is first performed. After anesthesia has been performed, the L-shaped arm 18 is removed from the base frame 3 and the leg plate 7 is removed to create an operating table that allows traction surgery as shown in FIGS. 3 and 4.

In addition, in FIGS. 7 and 8, the auxiliary plate 21 is installed on the base frame 3 by the support rod 22, but this is also unnecessary in the traction surgery and is removed. In addition, the groin support 10 can be deviated from the central axis position in the longitudinal direction of the operating table by rotating and adjusting the support tube 12 to change the position of the support rod 17. Facilitates fluoroscopic observation.

The invention is not limited to the illustrated embodiment. In particular, it is possible to select the low or high position of the leg plate 7 other than by using an L-shaped arm; for example, a mechanism that can be retracted and installed using a bendable or rotatable support arm fixed to the base frame can be adopted. .
The structure of the traction mechanism and the attachment support mechanism to the base frame are also not limited to the illustrated example. It is also possible to move the patient's upper body support up and down by operating the operating handle or electrically.

According to the present invention, general surgery and orthopedic surgery can be performed on one operating table, which is economical because it does not take up much space, and the operating table can be easily disassembled and assembled.
