Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a tibial osteotomy leg position adjustment and fixing device. Background Art

[0002] Tibial osteotomy is an osteotomy that corrects the biomechanical axis of knee varus by appropriately sawing and expanding the bone gap on the inside of the tibia, filling it with artificial bone prosthesis and fixing it with bone plates and bone screws. Since the tibia bone needs to be cut strongly to fix it during osteotomy, it is very easy to cause the leg to deviate and shake during osteotomy. Therefore, it is extremely important to be able to flexibly adjust the leg position during osteotomy to ensure the accuracy of the subsequent osteotomy benchmark and to firmly fix the leg to ensure the stability of the operation.

[0003] In the prior art, medical personnel usually adjust the patient's leg to the surgical position according to the needs during osteotomy and then have the assisting medical personnel hold the patient's leg with their hands to ensure that the leg does not shake violently or move suddenly during the osteotomy operation.

[0004] At present, the existing technology assists medical personnel in holding the patient's leg to be osteotomized directly with their hands to keep the leg fixed during the osteotomy operation. However, this cannot firmly and stably limit the deviation and shaking of the leg. As a result, the patient may still twitch due to sudden stimulation or shake due to the large osteotomy force during the operation, resulting in deviations and errors in the osteotomy operation and causing the operation to fail. In addition, manual adjustment alone cannot accurately ensure that the leg is in the precise surgical position before the operation, resulting in deviations in the osteotomy benchmark of subsequent operations. Utility Model Content

[0005] In view of this, the purpose of the utility model is to propose a tibial osteotomy leg posture adjustment and fixation device, which solves the problems of failure of osteotomy surgery due to deviation in subsequent surgery caused by the inability to accurately adjust the leg posture before surgery and shaking and deviation caused by loose leg fixation, by providing a device with precise leg posture adjustment structure and stable posture fixation structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A tibial osteotomy leg posture adjustment and fixation device comprises a telescopic fixed base clamp, the upper end of the telescopic fixed base clamp is provided with a rotating table which is rotated by an electric rotating shaft, the top of the rotating table is provided with a leg clamp sleeve which is rotated by an electric rotating sleeve, a controller is fixedly provided on the outer side of the telescopic fixed base clamp, and the controller is connected with the telescopic fixed base clamp, the electric rotating shaft, the electric rotating sleeve and the leg clamp sleeve through lines.

[0008] Furthermore, an inflatable fixing sleeve is provided inside the leg jacket, and the inflatable fixing sleeve is connected to the controller via a line.

[0009] Furthermore, the leg jacket is composed of a support rod, a lower jacket and an upper jacket. The bottom of the support rod is fixedly connected to the electric rotating jacket, the top of the support rod is fixedly connected to the lower jacket, the right side of the lower jacket is connected to the right side of the upper jacket through a rotating hinge, and the left side of the lower jacket is locked with the left side of the upper jacket through a locking buckle.

[0010] Furthermore, an anti-slip coating is fixedly provided on the inner side of the telescopic fixed base clamp.

[0011] Furthermore, the telescopic fixed base clamp, the electric rotating shaft, the electric rotating sleeve and the leg clamp sleeve are all provided with a waterproof coating.

[0012] Furthermore, the telescopic fixed base clamp, the electric rotating shaft, the electric rotating sleeve and the leg clamp sleeve are all made of stainless steel.

[0013] The utility model has the following beneficial effects:

[0014] The utility model proposes a device that has both a precise leg posture adjustment structure and a stable posture fixing structure. The controller accurately controls the electric rotating shaft and the electric rotating sleeve to achieve precise adjustment of the leg posture before surgery, avoiding deviations in subsequent surgeries. The leg is firmly fixed by the leg clamp combined with the inflatable fixing sleeve to avoid shaking during the operation, greatly improving the success rate of the operation.
