Next, how to use this surgical operating table l will be explained.

First, the patient is carried from the bed to the surgical operating table 1 and placed in a prone position as shown in FIG.

At this time, the arm of the patient P is supported by the table IO, which is movable in the front-back direction. Further, the feet and knees of the patient P are supported by a foot plate 15 and a knee support part 20, respectively. The vertical position of the foot plate 15 is adjusted by loosening the lock mechanism 16 and moving the foot plate 15 to an appropriate position on the vertical frame 5, and then tightening and fixing the lock mechanism 16. To adjust the angle, loosen the lock mechanism 17 and rotate the foot plate 15 to an appropriate rotation angle.
After that, each time the locking mechanism 17 is tightened. Similarly, the vertical position and angle of the knee rest portion 20 are adjusted by opening and closing the locking mechanisms 21 and 22, respectively. The vertical position of the chair 25 is adjusted by moving the lever 62 of the jack 60 up and down to raise the cylinder rod 61 to an appropriate height.

Further, the position adjustment of the chair 25 in the front and back direction is performed using a lock mechanism 50.
Loosen the lever 54 to move the slide block 41 to an appropriate position on the T-shaped rail 42, and then loosen the lever 54.
This is done by tightening.

In this way, the foot plate can be adjusted according to individual differences in the patient's physique.
The support members 5, 20, etc. can be fitted to various parts of the patient's body. Thereby, the patient P can be supported correctly and safely on the operating table 1. Roughly speaking, during this support, the patient P is placed on the table 10. Footboard 15. Since the knee rest is supported by the part 20 and the chair 25, the number of parts required to support the patient can be reduced compared to the conventional one, thereby making it possible to obtain an inexpensive dedicated operating table.

Next, while supporting the patient P in the prone position, the operating table 1 is moved toward the column 7, and the shaft 6 below the upper frame 3 is placed above the bracket 8 (see FIG. 1). In this state, raise the bracket 8 and insert the shaft 6 into the bracket 8.
be inserted. When the bracket 8 is further raised, the wheels 31a and 32a leave the floor, and the operating table 1 is lifted above the floor. Next, the pedal 76 is depressed downward.

Then, the stepped shaft 75 (Fig. 5) together with the pedal 76,
It moves downward against the spring force of the coil spring 78. As a result, the upper surface 76a of the pedal 76 and the cylindrical member 71
A gap is generated between the lower surface 71b of the cylindrical member 71 and the arm 70, and the cylindrical member 71 and the arm 70 move downward under their own weight, and the protrusion 71
a separates from the notch 73a. Next, the arm 70 is rotated around the large diameter portion 75a of the stepped shaft 75 (the state shown in the dashed line in FIG. 2 and in FIG. 6).

In this way, during surgery, the leg frame member 32 can be stored in a position where it does not interfere with the surgeon's feet, so that sufficient space can be secured for the feet of the surgeon. This allows the surgery to be performed smoothly.

[Effects of the Invention] In the surgical operating table according to the present invention, the patient is supported by the table, foot plate, knee rest and chair, so the number of parts required to support the patient is reduced compared to conventional ones. can be reduced,
As a result, a dedicated surgical operating table used for surgeries on the lumbar spine and the like can be realized at low cost.
