Description

[Detailed description of the invention] This invention is a groin fixation device for an operating table, which is used when performing orthopedic surgery by having a patient with a femoral fracture lying on their side on the operating table, fixing the groin, and pulling the legs. It is related to.

During orthopedic surgery for femoral fractures or femoral surgery, which involves inserting a stainless steel or other non-corrosive material into the broken bone, the patient is placed in a lateral position on the operating table. The patient is laid down and the groin area is fixed in place before surgery is performed.

For example, FIG. 2 is a front view of a case of orthopedic surgery for a femoral fracture, in which the patient K is placed in a lateral position on the operating table 3. 3 is the top plate of the operating table, and 3' is also a top plate, on which the waist of the patient K is placed. Reference numeral 2 denotes a surgical platform installed on a column above the base 1, with supporting arms 4 extending laterally.
A support 7 is vertically installed on the end boss 5. 6 is a fixing screw for this support 7.

The post 7 is located on the abdomen of the patient K, and therefore the pad 10 is attached to the post 7 so that the abdomen of the patient K is supported. Furthermore, a groin fixing device (usually referred to as a groin column) P is installed on the post 7 via a fixing device consisting of a ferrule 8 and a ring 9, and this groin fixing device P holds the groin of the patient K in a fixed position. It is becoming fixed.

In this state, both legs of the patient K are pulled by the traction devices 13 and 14 installed on the fixed support frame 15, and a plastic surgery or the like is performed. The ferrule 8 has biting teeth on its disk surface and works together with the ring 9 to fix and hold the groin fixing device P. FIG. 3 is a plan view of the state shown in FIG. 2, viewed from above.

In the case of femoral joint surgery, as shown in FIG. 4, the surgery is performed with the hip joint opened in a certain manner, and the lower leg is fixed to the leg brace 16.
As is clear from the plan view of FIG. 5 showing the state of FIG. 4 from above, one traction device 13 is used to traction the thigh, and the other traction device 14 is used to traction the lower limb. be done.

In FIGS. 4 and 5, the same reference numerals as in FIGS. 2 and 3 indicate the same parts as in FIGS. 2 and 3, and their functions are as described above. Also in this femoral jaw surgery, the groin region of the patient K is fixed by the fixture P.

By the way, in the past, the method of fixing the groin on such an operating table was to fix the groin at a fixed distance from the pillar 7. The groin support was replaced to adjust this distance accordingly.

This work is performed by nurses etc.
It is necessary to judge the distance from the patient's abdomen to the groin area, or if necessary, measure it and attach a groin support that matches the distance. Subject K will suffer pain as he is caught between the pillars. Further, there are drawbacks such as the need to prepare various groin supports and the need to store and organize them.

The present invention provides a groin fixation device that solves the drawbacks of the conventional groin fixation method.A rotating arm is attached to a column suspended above the operating table, and the end of the rotating arm has a special shape. It is equipped with a pad for fixing the crotch area.

The illustrated embodiment will be described below.

FIG. 1 is a plan view of the apparatus seen from above, in which numeral 7 is a column suspended above the operating table, and numeral 11 is a rotating arm rotatably attached to this column 7 via a ferrule 8. . Reference numeral 12 denotes a crotch fixing pad attached to the end of the rotating arm 11, and is bent with a constant radius of curvature. In the state shown in the figure, the groin is fixed at point A of the pad 12, and the ferrule 8 fixes the rotating arm 11 to the support 7 in this way. In this case, the distance between the abdominal pad and the groin area is l (usually 80 to 100 mm), which is adjusted for dwarfs.

For adults, adjust ferrule 8 and rotate arm 1.
Rotate 1 approximately 30 degrees counterclockwise to position the crotch fixing point at point B. In this case, the above distance is L (150 to 170 mm), which is suitable for adults. Since the rotation angle position of the rotation arm can be set to any position, the distance between the abdomen and the groin fixing position can be set to a desired size, thereby completely solving the conventional drawbacks.

In the illustrated example, the rotating arm is attached to the column using a ferrule and a ring, but the present invention is not limited to this structure, and various fixing mechanisms can be employed. The size of the groin fixation pad,
The shape, especially the curvature, is also not limited to the illustrated example.

As described above, the groin fixation device for the operating table according to the present invention can appropriately and quickly adjust the distance (size) between the abdomen and the groin, regardless of whether the patient is an adult or a child. Surgery can be performed in good conditions without causing pain to the surgeon. Adjustment of the crotch fixing position can also be performed very easily.
