[0039] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe a height-adjustable leg-lifting device for orthopedic surgery or several specific implementations of this utility model, and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up / down and left / right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of this height-adjustable leg-lifting device for orthopedic surgery are described in detail below:

[0040] Reference Figures 1-20 According to an embodiment of the present invention, a height-adjustable leg-lifting device for orthopedic surgery includes a connecting frame 1, a thigh support, a thigh fixation frame 3, a lower leg support, and a lower leg fixation frame 6. The connecting frame 1 is used to connect to the operating table. A rotation adjustment component is provided between the thigh support and the lower leg support to adjust the angle between them. The rotation adjustment component includes a rotating block 7 fixedly installed on the thigh support, a threaded hole 32 on the rotating block 7, a rotating groove 27 on the lower leg support, and a threaded fixing hole 36 on the rotating groove 27.

This is the conventional structure of a liftable leg raising device in orthopedic surgery.

[0041] However, current leg-raising devices also have shortcomings. Existing leg-raising devices in orthopedic surgery cannot accommodate patients of different heights. To solve this problem, the inventor adopted a telescopic structure, specifically designed as an adjustable telescopic rod.

[0042] The thigh support is divided into a thigh lifting frame 2 and a thigh telescopic rod 4. A sliding groove 3 56 is opened on one side of the thigh lifting frame 2, and the thigh telescopic rod 4 is slidably connected in the sliding groove 3 56.

The lower leg telescopic rod 14 slides in the lower leg rotating frame 5, and the threaded rod 26 is fixed in the threaded hole 34 and the threaded groove 25, so that different lower leg lengths can be adjusted. This structure can adjust the height-adjustable leg lifting device according to the patient's height.

[0043] In addition, to realize the lifting function of the device, the inventors considered adding a foot-operated lifting device, which not only realizes the lifting function, but also makes lifting more convenient.

[0044] A rotating assembly is provided on the connecting frame 1. The rotating assembly includes a rotating groove 16 fixedly installed on the connecting frame 1, a rotating column 31 fixedly installed in the rotating groove 16, and a rotating block 30 fixedly installed on the other side of the thigh lifting frame 2. The rotating block 30 is rotatably connected to the rotating column 31, thereby realizing the rotatable connection between the thigh lifting frame 2 and the connecting frame 1. The foot pedal lifting device structure includes a base 15. A connecting groove 45 is fixedly installed below the base 15. A rotating hole 49 is opened through the connecting groove 45. The rotating hole 49 is rotatably connected to a rotating rod 48 fixedly installed on the foot pedal 8. A connecting rod groove 58 is opened on the foot pedal 8, and a rotating hole 47 is opened in the connecting rod groove 58. The rotating hole 47 is rotatably connected to a rotating rod 46 fixedly installed on the connecting rod 12. At the same time, a weight 17 is fixedly installed on the foot pedal 8.

[0045] Connecting groove 1 43 and connecting groove 2 44 are fixedly installed above the base 15. A rotating hole 3 40 is opened on the side of connecting groove 1 43. The rotating hole 3 40 is rotatably connected to the rotating rod 3 38 fixedly installed on the connecting block 9. A rotating hole 2 41 is opened on one side of the connecting block 9. A rotating rod 2 37 is fixedly installed on the top of the connecting rod 12. The rotating rod 2 37 is rotatably connected to the rotating hole 2 41. A rotating hole 42 is opened on the other side of the connecting block 9. The rotating hole 42 is rotatably connected to the rotating rod 4 39. The rotating rod 4 39 is fixedly installed on the lifting adjustment rod 10. A rotating hole 1 35 is opened on the side of connecting groove 2 44. The rotating hole 1 35 is rotatably connected to the rotating rod 1 29. The rotating rod 1 29 is fixedly installed on the fixed adjustment rod 11. A weight 2 18 is fixedly installed on the fixed adjustment rod 11.

[0046] A rotating assembly two is provided at the bottom of the thigh fixation frame 3. The rotating assembly two includes a rotating block three 28 fixedly installed at the bottom of the thigh fixation frame 3, a rotating rod seven 50 fixedly installed on the rotating block three 28, the rotating rod seven 50 being rotatably connected to a rotating hole seven 51, the rotating hole seven 51 being opened on a rotating groove three 21, and the rotating groove three 21 being fixedly connected to a fixed rod 24. At least two fixed adjustment grooves 19 and a lifting adjustment groove 20 are opened on the fixed rod 24. The end of the fixed adjustment rod 11 is locked in the fixed adjustment groove 19, and the end of the lifting adjustment rod 10 is locked in the lifting adjustment groove 20.

[0047] Specifically, when the foot pedal 8 is pressed down, the foot pedal 8 drives the connecting rod 12 to move downward. Because the connecting block 9 is rotatably connected in the first connecting groove 43 and the connecting block 9 is rotatably connected to the lifting adjustment rod 10, when the connecting rod 12 drives the connection point with the connecting block 9 downward, the connecting block 9 drives the lifting adjustment rod 10 to rise against the lifting adjustment groove 20. The fixed adjustment rod 11 is rotatably connected to the second connecting groove 44. The fixed adjustment rod 11 slides down into the next fixed adjustment groove 19 as the lifting adjustment groove 20 rises. After the foot pedal 8 is released, the connecting rod 12 and the foot pedal 8 rise again under the gravity of the first weight 17. The fixed rod 24 loses the support of the lifting adjustment rod 10 and falls back down, while the fixed adjustment rod 11 slides down under the gravity of the second weight 18. The fixed adjustment rod 11 is stuck in the fixed adjustment groove 19, supporting the fixed rod 24. Repeating the above movements completes the upward movement.

[0048] To lower the device, press down the fixed adjustment rod 11 so that it leaves the fixed adjustment groove 19, and the fixed rod 24 loses its support. At the same time, press down the thigh fixing frame 3 to complete the descent of the device.

[0049] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
