[0002] At present, in gynecological, colorectal and anorectal surgeries, in order to fully expose the surgical field and better perform the surgery, patients are mostly placed in the lithotomy position. Medical staff will remove the calf support board on the operating table and place the patient's legs on the leg rest in the lithotomy position. After the operation, the patient enters the recovery stage. At this time, the patient is still in an anesthetized and muscle-relaxed state, but the lithotomy position needs to be changed to a supine position. The patient's legs need to be moved from the leg rest in the lithotomy position to the operating table. At this time, if there is no support from the calf support board of the operating table, it will have a great impact on the patient's postoperative safety and recovery.

The first screw 66 and the second screw 67 are both arranged parallel to the first slide rail 61 and the second slide rail 63. The first track frame 65 and the second track frame 64 are respectively provided with a first screw hole and a second screw hole for the first screw 66 and the second screw 67 to extend out. When in use, the first track frame 65 can be adjusted to move left and right for position adjustment by rotating the first screw 66, and the second track frame 64 can be adjusted to move left and right for position adjustment by rotating the second screw 67.

[0031] In this embodiment, guide sliding holes are provided on the first track frame 65 and the second track frame 64 along the front-to-back direction, and guide shafts are provided on the left and right inward ends of the first support plate 71 corresponding to the guide sliding holes, and the front-to-back sliding of the first support plate 71 is achieved through the cooperation between the guide sliding holes and the guide shafts.

[0032] In the present embodiment, the cross-sections of the first slide rail 61 and the second slide rail 63 are convex-shaped, the convex top surfaces of the first slide rail 61 and the second slide rail 63 are fixedly connected to the bed body 1, the upper edges of the first track frame 65 and the second track frame 64 are provided with convex holes corresponding to the first slide rail 61 and the second slide rail 63, at least one hanging rack 68 is provided between the bottoms of the first slide rail 61 and the second slide rail 63, the first track frame 65 and the second track frame 64 are hung between the first slide rail 61 and the second slide rail 63 through the convex holes, so as to realize the sliding connection of the first track frame 65 and the second track frame 64, and the hanging rack 68 is used for the placement of the telescopic legs when they are retracted.

[0033] In this embodiment, at least one placement groove 78 is provided on the left and right sides of the plate surface of the first support plate 71 and the second support plate 72, and a magnet block 79 is provided on the placement groove 78.
