[0026] The utility model provides a physical device for supporting the legs after hip and knee replacement surgery, comprising two C-shaped fixing frames and a sleeve 101, wherein the adjustment block comprises two sliders 115 and an adjustment block body 107. The above-mentioned solution solves the technical problem that the size of the C-shaped fixing frame cannot be adjusted, so that the device can only be suitable for some patients, thereby reducing the practicality of the device.
[0027] According to the present specific embodiment, the C-shaped fixing frame includes a first fixing frame 102 and a second fixing frame 103, one end of the first fixing frame 102 is provided with two hinge blocks 104, one end of the second fixing frame 103 is provided with a hinge seat 105, the outer sides of the first fixing frame 102 and the second fixing frame 103 are provided with two support blocks 106, an adjustment block is rotatably arranged between the two support blocks 106, a threaded groove 108 is arranged in the adjustment block, a spring 109 is arranged in the sleeve 101, both ends of the sleeve 101 are provided with an adjustment rod 110, one end of the adjustment rod 110 is rotatably arranged with a fixing seat 111, one side of the fixing seat 111 is provided with a groove 112, both inner sides of the groove 112 are provided with sliding grooves 113, a screw 114 is arranged in the groove 112, and the screw 114 runs through both ends of the groove 112, the hinge seat 105 is rotatably connected with the corresponding hinge block 104 through a connecting shaft, and is located between the two The adjusting block is slidably connected to the fixing seat 111 between the hinge blocks 104 and is located in the groove 112, and the screw 114 is threadedly connected to the adjusting block and is located in the thread groove 108. By splitting the structure of the C-shaped fixing frame into the first fixing frame 102 and the second fixing frame 103, the clamping diameters of the first fixing frame 102 and the second fixing frame 103 are adjusted by the screw 114, so that the device can be suitable for patients with different leg sizes, thereby improving the practicality of the device, and the limbs can be firmly fixed by the cooperation of the spring 109, the adjusting rod 110 and the two C-shaped fixing frames. The device can be taken out from between the two legs, which is simple to operate, the overall structure is compact and smart, and it is easy to carry. It can effectively prevent the lower limbs from being adducted, internally rotated, and externally rotated, and improve the comfort of the patient during the fixation process. It has good compliance, low cost, and can be reused, thereby reducing the patient fixation cost, saving manpower and material resources, and being easy to operate.
[0028] Among them, the two sliders 115 are respectively fixedly connected to the adjusting block body 107 and are located on both sides of the adjusting block body 107. The two sliders 115 are also respectively slidably connected to the fixing seat 111 and are located in the sliding groove 113. The adjusting block body 107 is slidably connected to the fixing seat 111 and is located in the groove 112. The adjusting block body 107 is rotatably connected to the corresponding support block 106 and is located between the two support blocks 106.

[0029] Secondly, a knob 116 is provided at one end of the screw rod 114, and a plurality of anti-slip strips 117 are provided on the outer side of the knob 116. The screw rod 114 can be easily rotated by the knob 116, and the anti-slip strips 117 can prevent the knob 116 from slipping, thereby improving the grip.
[0030] When the utility model is used to clamp a patient with a large leg diameter, the knob 116 is rotated to drive the screw 114 to rotate, and the screw 114 drives the two adjusting block bodies 107 to move in the directions away from each other in the fixing seat 111, so that the angles of the first fixing frame 102 and the second fixing frame 103 with the adjusting block change under the action of the two supporting blocks 106, and then the first fixing frame 102 and the second fixing frame 103 are moved in the directions away from each other under the action of the connecting shaft, and adjusted to a suitable diameter. When it is necessary to clamp a patient with a small leg diameter, the knob 116 is rotated in the opposite direction, so that the first fixing frame 102 and the second fixing frame 103 are moved in the directions close to each other under the action of the connecting shaft. In this way, the technical problem that the size of the C-shaped fixing frame cannot be adjusted, so that the device can only be suitable for some patients, thereby reducing the practicality of the device is solved.
