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 invention relates to the field of medical instruments, in particular to a guider for tibia osteotomy. The guider for tibia osteotomy comprises a broach, a first osteotomy surface positioning component and a second osteotomy surface positioning component, wherein the first osteotomy surface positioning component sleeves the broach and is slidably connected with the broach, the second osteotomy surface positioning component is connected with the first osteotomy surface positioning component, a feed groove is formed in the second osteotomy surface positioning component, the first osteotomy surface positioning assembly comprises a first sliding rod arranged on the broach in a sleeving mode, a positioning piece is arranged at the end, close to a tibia, of the first sliding rod, and a stress part is arranged at the end, away from the tibia, of the first sliding rod. The guider provided by the invention has the effect that the position of a tibia osteotomy surface is positioned more accurately 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, ...
