A gear 13 is fixedly connected to the outer surface of the rotating shaft 2. A limit assembly 14 is provided on the left side of the adjusting box 1. An installation device is fixedly connected to the back of the adjusting box 1. The frame 17 has a limit bolt 18 threadedly connected to the right side of the front of the mounting frame 17. One end of the limit bolt 18 extends into the inner cavity of the mounting frame 17. The bottom of the lifting rod 5 is fixedly connected to a guide plate 19. The left and right sides of the inner cavity of the positioning cylinder 4 are provided with guide grooves 20 that cooperate with the guide plate 19. The outer surface of the guide plate 19 is slidably connected to the inner surface of the guide groove 20. The top and bottom of the inner cavity of the cylinder 7 are provided with slide rails 21 that cooperate with the slide plate 8. The outer surface of the slide plate 8 is slidably connected to the inner surface of the slide rail 21.

[0033] In this embodiment: By setting a positioning cylinder 4, lifting rod 5, cylinder 7, sliding plate 8, pin plate 9, pin groove 10, spring 11, and pull rod 12, the present invention can easily adjust the support height of the L-shaped leg frame 6. By setting an adjustment box 1, rotating shaft 2, movable plate 3, and limiting component 14, the support angle of the L-shaped leg frame 6 can be easily adjusted. By setting a memory foam pad 22 and a through groove 23, the comfort of the L-shaped leg frame 6 can be improved, and the compression of nerves and blood vessels in the popliteal fossa of the patient can be avoided. By setting the above structure, it is easy to adjust and protect the patient, thereby meeting the patient's needs.

[0034] Example 2:

[0035] Reference Figure 2 and Figure 4 The limiting component 14 includes a screw 141, the outer surface of which is threadedly connected to the connection of the adjusting box 1. The right end of the screw 141 passes through the adjusting box 1 and is rotatably connected to a vertical plate 142 via a bearing. A toothed plate 143 is fixedly connected to the right side of the vertical plate 142, and the toothed plate 143 meshes with a gear 13. Slide rails 15 are fixedly connected to the top and bottom of the inner cavity of the adjusting box 1. The outer surface of the slide rails 15 is slidably connected to the inner surface of the vertical plate 142. A crank handle 16 is fixedly connected to the left end of the screw 141. A maintenance plate is fixedly installed on the front of the adjusting box 1 by screws.

[0036] In this embodiment: By setting the screw 141, the vertical plate 142 and the toothed plate 143, the present invention can conveniently limit the position of the gear 13.

[0037] The implementation principle of this utility model is as follows: In use, the operator fixes the device on the examination or operating table frame by using the mounting frame 17 and the limiting bolt 18. Then, when it is necessary to adjust the use angle of the L-shaped leg frame 6 laterally, the operator rotates the positioning cylinder 4, which causes the movable plate 3 to rotate around the rotating shaft 2. At the same time, the positioning cylinder 4 drives the lifting rod 5 and the L-shaped leg frame 6 to rotate. When the L-shaped leg frame 6 rotates to the appropriate use angle, the operator rotates the rocker handle 16, which causes the screw 141 to rotate on the inner surface of the adjusting box 1. At the same time, the screw 141 drives the vertical plate 142 to slide on the outer surface of the slide rail 15, thereby causing the vertical plate 142 to drive the toothed plate 143 to move and mesh with the gear 13, thereby limiting the gear 13 and the rotating shaft 2, thus completing the lateral adjustment of the use angle of the L-shaped leg frame 6.

[0038] When the height of the L-shaped leg bracket 6 needs to be adjusted, the operator moves the L-shaped leg bracket 6 upward, causing the lifting rod 5 to slide upward on the inner surface of the positioning cylinder 4. As the lifting rod 5 slides upward, it presses the pin plates 9 on both sides, causing the pin plates 9 to slide on the inner surface of the slide rail 21 and press the spring 11. This causes the pin plates 9 to enter the inner cavity of the cylinder 7. When the L-shaped leg bracket 6 moves upward to the appropriate height, and the lifting rod 5 moves the pin groove 10 to the corresponding position of the pin plate 9, the spring 11 pushes the slide plate 8 to move in the opposite direction under the reaction force. This causes the slide plate 8 to move the pin plate 9 in the opposite direction and insert it into the inner cavity of the pin groove 10, thus limiting the lifting rod 5 and completing the adjustment of the height of the L-shaped leg bracket 6.

[0039] When the L-shaped leg support 6 needs to be restored to its initial position, the operator simultaneously pulls the levers 12 on both sides. This causes the levers 12 to move the slide plate 8 along the inner surface of the slide rail 21, compressing the spring 11. This causes the pin plate 9 to move out of the inner cavity of the pin groove 10, releasing the limit on the lifting rod 5. At the same time, the lifting rod 5 and the L-shaped leg support 6 slide downwards under the action of gravity to return to their initial positions. In addition, the memory foam padding 22 and the through groove 23 can improve the comfort of the L-shaped leg support 6 and prevent the patient's popliteal fossa from continuous contact with the rigid contact surface of the lithotomy position surgical leg support, thus avoiding nerve and blood vessel compression in the patient's popliteal fossa. The device is simple to operate and easy to adjust for protective use, thereby meeting the needs of patients.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
