When the patient's knee joint needs to be adjusted during the operation, the sliding shell 11 can be moved on the operating table 1 by pulling the first lower limb shelf 2 and the second lower limb shelf 3 to adjust the required angle.

[0027] At the same time, two groups of mounting seats 5 are fixedly connected to the outer wall of the operating table 1. The outer wall of each group of mounting seats 5 is fixedly connected to a support rod 6. A fixing block 7 is fixedly connected between the two groups of support rods 6. The top of the fixing block 7 is rotatably connected to a rotating rod 8. The outer wall of the rotating rod 8 is fixedly connected to a foot shelf 9. When surgery is needed on the patient's foot, the patient's calf can be lifted and the patient's foot can be placed on the foot shelf 9, which is convenient for the doctor to examine the patient's foot. If the foot does not need to be examined, the rotating rod 8 can be rotated to rotate the foot shelf 9 to the side. The foot shelf 9 can even be removed from the operating table 1 by disassembling the support rod 6 and the mounting seat 5.

[0028] Furthermore, one end of the bottom of the first lower limb shelf 2 and the second lower limb shelf 3 are both fixedly connected to a connecting block 15, the outer wall of the connecting block 15 is fixedly connected to a sliding shell 11, the sliding shell 11 is rotatably connected to a knob 10, the sliding shell 11 is movably connected to a lifting ring 12, the outer wall of the lifting ring 12 is rotatably connected to two groups of connecting rods 13, and each group of connecting rods 13 is rotatably connected to a limiting block 14. When the required angle is adjusted, the user can turn the knob 10 to drive the lifting ring 12 inside the sliding shell 11 to descend, thereby lowering the connecting rod 13, and then moving the limiting block 14 toward the two ends inside the operating table 1, so that the limiting block 14 can be just stuck in the teeth on both sides of the slide groove of the operating table 1, so that the first lower limb shelf 2 and the second lower limb shelf 3 can be fixed at the angle required for surgery, thereby fixing the patient's knee joint.

[0029] See also Figure 1 、 Figure 2 and Figure 3 A surgical waste liquid collection pad 16 is placed on the top of the operating table 1.

[0034] When the patient's knee joint needs to be adjusted during surgery, the first lower limb shelf 2 and the second lower limb shelf 3 can be pulled to drive the sliding shell 11 to move on the operating table 1 to adjust the required angle;

[0035] When the desired angle is adjusted, the user can turn the knob 10 to drive the lifting ring 12 inside the sliding shell 11 to descend, thereby lowering the connecting rod 13 and moving the limit block 14 toward the two ends inside the operating table 1;

[0036] The limiting block 14 can be exactly stuck in the teeth on both sides of the slide of the operating table 1, so that the first lower limb shelf 2 and the second lower limb shelf 3 can be fixed at the angle required for surgery, thereby fixing the patient's knee joint;

[0037] When surgery is required on the patient's foot, the patient's calf can be lifted and the patient's foot can be placed on the foot rest 9 to facilitate the doctor to examine the patient's foot;

[0038] If the foot does not need to be inspected, the rotating rod 8 can be rotated to rotate the foot shelf 9 to the side, and the foot shelf 9 can even be removed from the operating table 1 by disassembling the support rod 6 and the mounting base 5;

[0039] At the same time, a surgical waste liquid collection pad 16 is also provided on the operating table 1, which can collect various waste liquids generated during the operation, making it convenient for the user to clean the operating table 1 after the operation;

[0040] In summary, the sliding shell 11 cooperates with the first lower limb shelf 2 and the second lower limb shelf 3 to adjust the flexion angle of the patient's knee joint. Then, the knob 10 cooperates with the lifting ring 12, and the limit block 14 is controlled by the linkage rod 13 to fix the first lower limb shelf 2 and the second lower limb shelf 3.

[0041] According to the needs of the user, different parts of the patient are tested. By installing the foot rest 9, the patient's foot can be tested and fixed, thereby solving the technical problem of manually lifting the thigh of the affected limb to maintain knee flexion or fix the knee joint during the operation, thereby saving manpower and improving the efficiency of the operation.
