[0024] The first support seat 2 and the second support seat 3 are placed on both sides of the base, a length adjustment component is fixed between the first support seat 2 and the second support seat 3, a through hole 7 is opened on the side of the base 1, and the length control knob 4 passes through the through hole 7 and is connected to the length adjustment component to adjust the distance between the first support seat 2 and the second support seat 3.

[0025] Among them, the length adjustment assembly includes a screw rod 8, a first connecting rod 9, a second connecting rod 10, a third connecting rod 11, a fourth connecting rod 12, a first nut 13 and a second nut 14, the screw rod 8 is fixedly connected to the length control knob 4, the first nut 13 and the second nut 14 are both screwed on the screw rod 8, the first nut 13 and the second nut 14 are arranged in reverse teeth, one end of the first connecting rod 9 and one end of the second connecting rod 10 are both hinged to the first support seat 2, the other end of the first connecting rod 9 is fixedly connected to the first nut 13, the other end of the second connecting rod 10 is fixedly connected to the second nut 14, one end of the third connecting rod 11 and one end of the fourth connecting rod 12 are both hinged to the second support seat 3, the other end of the third connecting rod 11 is fixedly connected to the second nut 14, the other end of the fourth connecting rod 12 is fixedly connected to the first nut 13, the first connecting rod 9, the second connecting rod 10, the third connecting rod 11 and the fourth connecting rod 12 form a parallelogram.

[0026] The first height adjustment component and the second height adjustment component are respectively provided at both ends of the base 1. The first height control handle 5 is hinged to the side of the first support seat 2 so that the first height control handle can only move horizontally but not vertically and is clamped on the first height adjustment component. The second height control handle is hinged to the side of the second support seat 3 so that the second height control handle can only move horizontally but not vertically and is clamped on the second height adjustment component to adjust the height of the natural latex pad 6.

[0027] Among them, the first height adjustment component includes a long adjustment hole 15 and a plurality of bayonet holes 16 opened at one end of the base 1, the long adjustment hole 15 is vertically arranged, and the plurality of bayonet holes 16 are horizontally arranged and connected with the long adjustment hole 15, and the handle end of the first height control handle 5 is penetrated by the long adjustment hole 15, and the bayonet holes 16 are snap-connected with the first height control handle 5.

[0028] The second height adjustment component has the same structure as the first height adjustment component, and the second height control handle has the same structure as the first height control handle, which will not be described in detail here.

[0029] The natural latex pad 6 is covered on the upper part of the first support seat 2 and the second support seat 3, and the natural latex pad 6 is attached to the first support seat 2 and the second support seat 3 by Velcro. The natural latex pad 6 is provided with a first arc-shaped body 17 matching the shape of the popliteal fossa of the human lower limb, a second arc-shaped body 18 matching the shape of the calf of the human lower limb, and a third arc-shaped body 19 matching the shape of the ankle of the human body. The top shape of the first support seat 2 matches the shape of the natural latex pad 6 directly above, and the top shape of the second support seat 3 matches the shape of the natural latex pad 6 directly above.

[0030] When used after surgery for varicose veins in the patient's lower limbs, the patient's lower limbs are placed on the natural latex pad 6, and the length control knob 4 is rotated to drive the screw 8 to rotate. The first nut 13 and the second nut 14 move in relative opposite directions on the screw due to the reverse tooth setting (such as moving toward the middle of the screw at the same time or moving toward the two ends of the screw at the same time), thereby driving the first connecting rod 9 and the second connecting rod 10 connected to the first support seat 2 and the third connecting rod 11 and the fourth connecting rod 12 connected to the second support seat 3 to move in relative opposite directions (such as moving toward the middle of the base at the same time to reduce the distance between the first support seat 2 and the second support seat 3, or moving toward the two ends of the base at the same time to increase the distance between the first support seat 2 and the second support seat 3). The length of the lower limb lifting device is adjusted by this adjustment method.

[0031] Place the first height control handle 5 in the corresponding long adjustment hole 15, place the second height control handle in the corresponding long adjustment hole, and raise or lower the first support seat 2 and the second support seat 3 at the same time. After raising or lowering the first support seat 2 and the second support seat 3 to the appropriate height, operate the first height control handle 5 and the second height control handle, clamp the first height control handle 5 in the bayonet 16 flush with its height, and clamp the second height control handle in the bayonet flush with its height. The height of the lower limb lifting device can be adjusted by this adjustment method.

[0032] Finally, the patient's popliteal fossa is placed on the convex first arc-shaped body 17, the patient's lower limb calf is placed on the concave second arc-shaped body 18, and the patient's ankle is placed on the concave third arc-shaped body 19. By adjusting the length and height of the lower limb lifting device, the length and height of the lower limb lifting device are matched with the patient's height to increase the patient's comfort. The patient's popliteal fossa, lower limb calf and ankle are respectively placed in arc-shaped bodies that match their shapes to further increase the patient's comfort.
