[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1-3, an embodiment provided by the present utility model: an adjustable and fixed protection device for the legs in the anesthetic lithotomy position, including a leg support 1. An angle adjustment mechanism is provided at the bottom end of the leg support 1. The angle adjustment mechanism includes a hinge member 9. The top end of the hinge member 9 is fixedly connected to the bottom end of the leg support 1. By the top end of the hinge member 9 providing a fixed support effect for the leg support 1, when the hinge member 9 makes an arc movement, it can drive the leg support 1 to move together. The inner wall of the hinge member 9 is hinged with a hinge frame 10 through a rotating rod 4. By the outer wall of the rotating rod 4, the hinge member 9 can make an arc movement along the inner wall of the hinge frame 10. A baffle 16 is fixedly connected to the outer wall of the rotating rod 4. By fixedly connecting the baffle 16 to the outer wall of the rotating rod 4, when the rotating rod 4 rotates, it can drive the baffle 16 to rotate together, and it can also drive the baffle 16 to squeeze the spring 14 by pulling the rotating rod 4. The outer wall of the baffle 16 is elastically connected to the inner wall of the hinge frame 10 through a spring 14. By the elastic force of the spring 14, the baffle 16 can always drive the rotating rod 4 to move inward without being affected by external forces. A clamping ring 12 is fixedly connected to the outer wall of the rotating rod 4. By fixedly connecting the clamping ring 12 to the outer wall of the rotating rod 4, when the rotating rod 4 rotates, it can drive the clamping ring 12 to rotate together, and it can also be clamped with a clamping frame 11. The outer wall of the clamping ring 12 is clamped with a clamping frame 11. By the inner wall of the clamping ring 12 clamping the clamping frame 11, after the clamping ring 12 is clamped with the clamping frame 11, the rotating rod 4 can be fixed on the outer wall of the hinge frame 10. The outer wall of the clamping frame 11 is fixedly connected to the outer wall of the hinge frame 10. By the outer wall of the clamping frame 11 being fixedly connected to the outer wall of the hinge frame 10, after the rotating rod 4 is fixed on the hinge frame 10 due to the clamping of the clamping ring 12 and the clamping frame 11, it will not rotate under the influence of external forces.

[0033] Refer to Figure 1 , Figures 4-5 , a support column 5 is fixedly connected to the bottom end of the hinge frame 10. By the top end of the support column 5 providing a fixed support effect for the hinge frame 10, a sleeve 7 is fixedly connected to the bottom end of the support column 5. By fixedly connecting the sleeve 7 to the bottom end of the support column 5, when the sleeve 7 moves horizontally, it can drive the support column 5 to move together. A rod body 3 is slidably connected to the inner wall of the sleeve 7. By the rod body 3 being slidably connected to the inner wall of the sleeve 7, the sleeve 7 can move horizontally along the outer wall of the rod body 3.

[0034] Refer to Figure 1 , Figures 4-5, a bolt 6 is threadedly connected to the inner wall of the sleeve 7. By threadedly connecting the bolt 6 to the inner wall of the sleeve 7, the bolt 6 can be laterally moved along the inner wall of the sleeve 7. The bottom end of the bolt 6 is in contact connection with the outer wall of the rod body 3. By the bottom end of the bolt 6 being in contact connection with the outer wall of the rod body 3, when the bolt 6 is rotated, the bottom end of the bolt 6 presses the rod body 3, achieving the effect of fixing the sleeve 7 on the outer wall of the rod body 3, and achieving the effect that the sleeve 7 will not move laterally under the influence of external forces.

[0035] Refer to Figure 1 , Figures 4-5 , a chute 8 is formed on the outer wall of the rod body 3. By forming the chute 8 on the outer wall of the rod body 3, the slider 13 can be laterally moved along the inner wall of the chute 8. The slider 13 is fixedly connected to the inner wall of the sleeve 7. By fixedly connecting the slider 13 to the inner wall of the sleeve 7, the sleeve 7 can drive the slider 13 to move together when moving laterally. The outer wall of the slider 13 is slidably connected to the inner wall of the chute 8. By the outer wall of the slider 13 being slidably connected to the inner wall of the chute 8, the sleeve 7 will not rotate along the outer wall of the rod body 3, and the sleeve 7 will always move laterally along the inner wall of the chute 8.

[0036] Refer to Figure 3 , one end of the spring 14 is in contact connection with the outer wall of the baffle 16, and the other end of the spring 14 is fixedly connected to the inner wall of the hinge frame 10. By the elastic force of the spring 14, when the rotation rod 4 stops being pulled, it can be immediately reset by the elastic force of the spring 14, and because one end of the spring 14 is disconnected from the baffle 16, when the rotation rod 4 drives the baffle 16 to rotate, it will not drive the spring 14 to rotate together.

[0037] Refer to Figure 1 , a sponge pad 2 is fixedly connected to the top end of the leg support 1. By fixedly connecting the sponge pad 2 to the top end of the leg support 1, a relatively comfortable effect is provided for the patient's legs.

[0038] Refer to Figure 3 , a limiting block 15 is fixedly connected to the outer wall of the rotation rod 4. By the outer wall of the rotation rod 4 providing support and fixation for the limiting block 15, when the rotation rod 4 rotates, it can drive the limiting block 15 to rotate together. The outer wall of the limiting block 15 is slidably connected to the inner wall of the hinge member 9. By the outer wall of the limiting block 15 being slidably connected to the inner wall of the hinge member 9, when the rotation rod 4 moves laterally along the inner wall of the hinge member 9, it will drive the hinge member 9 to rotate due to the limiting block 15.

[0039] Refer to Figures 2-3, the outer wall of the rotating rod 4 penetrates and is rotatably connected to the inner wall of the hinge frame 10. Through the penetration and rotational connection between the outer wall of the rotating rod 4 and the inner wall of the hinge frame 10, the rotating rod 4 can rotate along the inner wall of the hinge frame 10, and can also move horizontally along the inner wall of the hinge frame 10. The outer wall of the rotating rod 4 penetrates and is slidably connected to the inner wall of the hinge member 9. Through the penetration and sliding connection between the outer wall of the rotating rod 4 and the inner wall of the hinge member 9, the rotating rod 4 can move horizontally along the inner wall of the hinge member 9.

[0040] Working principle: When using the device, first fix the rod body 3 of the device on both sides of the hospital bed. Then, first rotate the bolt 6 to release the fixation between the sleeve 7 and the rod body 3. Then, push the support column 5. After the leg support 1 moves to a suitable position, rotate the bolt 6 in the reverse direction to fix the sleeve 7 and the rod body 3, so that the device will not move horizontally due to external forces. Then, first pull the rotating rod 4 to drive the clamping ring 12 to release the clamping with the clamping frame 11. Then, rotate the rotating rod 4 to drive the leg support 1 fixed at the top of the hinge member 9 to rotate. When it rotates to a suitable position, release the rotating rod 4. The rotating rod 4 will, due to the elastic force of the spring 14, cause the clamping ring 12 to be clamped with the clamping frame 11, so as to achieve the effect of fixing the rotating rod 4 and fixing the leg support 1 to a suitable position. Then, place the patient's leg on the leg support 1.
