Abstract

The present application relates to the technical field of medical devices, in particular to an auxiliary osteotomy device for the proximal tibia, which includes a fine-tuning component installed on one end of the upright pole away from the ankle brace, and the fine-tune component includes a fine-tuning component that is fixedly connected to the upright pole An installation post at one end, an adjustment button rotatably arranged on the installation post, and a square fine-tuning rod arranged on the installation post, the installation post and the adjustment knob are coaxially arranged with the vertical pole, and the installation post is provided with a There is an installation groove, the adjustment button is rotated and arranged in the installation groove, the end of the installation post away from the vertical pole is provided with a limit groove connected to the installation groove, and the fine adjustment rod is slidably fitted in the limit groove, so A screw rod fixedly connected with one end of the fine-tuning rod is arranged inside the installation column, the screw rod passes through the knob and the two are screwed together. The present application has the effect of improving the amount of tibial osteotomy and the problem that the osteotomy block cannot adjust the retroversion angle by adjusting the fine adjustment assembly and the tibial fixation plate.

Description

technical field [0001] The present application relates to the technical field of medical devices, and in particular, to an auxiliary osteotomy device for the proximal end of the tibia. Background technique [0002] At present, for patients with early knee joint disease, unicondylar joint replacement surgery is a widely used and effective treatment method. Unicondylar joint replacement surgery has the advantages of less trauma, quick recovery, bone preservation, and good joint stability. , On the premise of not destroying the original proprioception and soft tissue balance system of the patient's knee joint, the patient's knee joint motor function is preserved to the greatest extent, and the patient's satisfaction with the quality of rehabilitation is improved. The accuracy required by unicondylar joint replacement technology is relatively high, and clinical studies have confirmed that the accuracy of the prosthesis installation position directly affects the prosthesis surviv...
