Problems solved by technology

[0003] Most tibial osteotomy positioning instruments in the related art are extramedullary positioning, and the operation steps are complicated. Extramedullary positioning can only rely on visual observation of the osteotomy position, which not only affects the accuracy of the instrument, but also increases the risk of surgery
[0004] For the above-mentioned technology, the inventor believes that there is a defect in the related art that the tibial osteotomy positioning instrument is inaccurately positioned

Abstract

The present application relates to the field of medical devices, in particular to a tibial osteotomy guide. A tibial osteotomy guide, comprising: a medullary needle, a first osteotomy surface positioning assembly sleeved on the medullary needle and slidingly connected with the medullary needle, and a second osteotomy surface positioning assembly connected with the first osteotomy surface positioning assembly Assemblies, the second osteotomy surface positioning assembly is provided with a knife-feed slot. The first osteotomy surface positioning assembly includes a first sliding rod sheathed on the medullary needle, a positioning member is provided at an end of the first sliding rod close to the tibia, and a force-receiving part is provided at an end far away from the tibia. The present application has the effect of making the position of the tibial osteotomy surface more accurate in knee joint replacement.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to a tibial osteotomy guide. Background technique [0002] Knee arthroplasty is currently one of the commonly used surgical methods in the clinical treatment of knee osteoarthritis, traumatic arthritis, rheumatoid and other diseases, and it has the characteristics of good postoperative effect. In total knee replacement surgery, it is necessary to perform a plane osteotomy on the tibia of the knee joint, and then install the tibial prosthesis using the osteotomy plane as the reference plane. [0003] Most tibial osteotomy positioning instruments in the related art are extramedullary positioning, and the operation steps are complicated. Extramedullary positioning can only rely on visual observation of the osteotomy position, which not only affects the accuracy of the instrument, but also increases the risk of surgery. [0004] With regard to the above-mentioned technologies, ...
