[0025] The leg support 1, designed for the lithotomy position, serves as a support device for the patient's legs. Its top surface features an array of movable grooves 9 to accommodate and guide the vertical movement of massage blocks 11. Limiting grooves 10 are located on both sides of the movable grooves 9. An internal mounting groove 13 is provided for mounting and securing a mounting frame 14 and the compression blocks 17 on it. When the mounting frame 14 is installed in the mounting groove 13, it prevents the massage blocks 11 from falling out of the movable grooves 9. First Velcro 6 is attached to both sides of the leg support 1, which engages with second Velcro 7 at the bottom of the cushion 8 to secure it. The cushion 8 is made of a soft material, directly contacting the patient's legs to provide comfort and cushioning, reducing pressure. A spherical mounting post 2 is integrally formed at the bottom of the leg support 1 for connecting and securing the base rod 3. The spherical bottom design of the mounting post 2 allows it to rotate and adjust within a certain angle range within the mounting sleeve 4, thereby adjusting the leg support 1 to accommodate different surgical positions. The mounting post 2 is installed inside the mounting sleeve 4, and the two are shaped to fit each other. The base rod 3 is L-shaped and integrally formed with the mounting sleeve 4 for mounting on the operating table. The fastening screw 5 passes through the mounting sleeve 4 and abuts against the mounting post 2 inside. By tightening the screw, pressure can be applied to the mounting post 2 to fix the leg frame 1 at a specific rotation angle. The soft pad 8 covers the top of the leg frame 1, providing comfortable support and cushioning for the patient's legs. Its two ends are sewn with second Velcro 7, which is bonded to the first Velcro 6 on both sides of the leg frame 1 to fix the soft pad 8. The massage block 11 is installed inside the movable groove 9 at the top of the leg frame 1.

The mounting bracket 22 is fixed in the mounting groove 13 of the leg bracket 1 by bolts, and is used to support one end of the lead screw 21 and install the servo motor 20. Specific Implementation Example 2:

[0027] Reference Figure 1-5 A multifunctional surgical positioning and adjustment frame, further based on the basic structure in Specific Embodiment 1, is used by connecting a servo motor 20 via a wire, which drives the lead screw 21 to rotate. Since the lead screw 21 is threadedly engaged with the slider 18 at the bottom of the compression block 17, the rotational motion of the lead screw 21 is converted into linear motion of the slider 18 and the compression block 17 along the axial direction of the lead screw 21. Guide blocks 19 on both sides of the bottom surface of the compression block 17 slide within the guide groove 16 on the top surface of the mounting frame 14, allowing the compression block 17 to move smoothly. As the compression block 17 moves, it sequentially compresses the bottom of the massage block 11 above it in the direction of movement, causing the top of the massage block 11 to protrude from the movable groove 9 at the top of the leg frame 1, thereby massaging the patient's legs. After the compression block 17 is in position, the servo motor 20 rotates in the opposite direction, causing the compression block 17 to move back and compress the massage block 11 on the other side again. By rotating the servo motor 20 in both directions, the compression block 17 reciprocates within the mounting frame 14, driving the massage block 11 to protrude alternately, providing intermittent pressure massage to the patient's legs, stimulating leg muscles, promoting blood circulation, and thus alleviating the numbness and pain in the lower limbs caused by maintaining the lithotomy position for a long time.

[0028] In summary:

[0029] 1. By connecting the wire to the servo motor 20, the servo motor 20 is started and drives the lead screw 21 to rotate. When the lead screw 21 rotates, the threads on the lead screw 21 and the slider 18 mesh with each other, causing the slider 18 to move along the axial direction of the lead screw 21. When the slider 18 moves, it will drive the squeezing block 17 to move together. When the squeezing block 17 moves, it will squeeze the bottom of the massage block 11 in the direction of movement in sequence, so that the bottom end of the massage block 11 is squeezed out of the movable groove 9 by the squeezing block 17, thereby massaging the patient's legs. When the squeezing block 17 moves into place, the servo motor 20 rotates in the opposite direction, causing the squeezing block 17 to move back, thereby squeezing the massage block 11 again. The massage block 11 massages the patient's legs, stimulates the leg muscles, and promotes blood circulation. This solves the disadvantage of maintaining the lithotomy position for a long time, which causes the patient's leg muscles to be in a state of tension, blood circulation to be obstructed, and is prone to numbness and pain in the lower limbs.
