Abstract

The invention relates to an osteotomy positioning device,. The device comprises an extramedullary positioning rod, an osteotomy plate, a first adjusting mechanism, a ankle holding device and a secondadjusting mechanism, wherein the upper end of the extramedullary positioning rod is provided with an osteotomy fixing seat, the osteotomy plate is arranged on the osteotomy fixing seat and used for positioning the osteotomy position of a tibial plateau, the first adjusting mechanism is arranged between the extramedullary positioning rod and the osteotomy fixing seat and used for adjusting the distance between the osteotomy fixing seat and the upper end of the extramedullary positioning rod, the ankle holding device is arranged at the lower part of the extramedullary positioning rod and is usedfor wrapping and fixing an ankle joint, and the second adjusting mechanism is arranged on the extramedullary positioning rod and used for adjusting the length of the extramedullary positioning rod. According to the device, fixing nails do not need to be punched on the tibial plateau for fixing, and the damage to sclerotin of a patient is reduced; the position of the osteotomy plate can be rapidlyand accurately adjusted to adjust osteotomy errors, and the implementation efficiency of surgical operation is improved; and the osteotomy plate can be assisted to be fixed in real time through the fixing effect of the extramedullary positioning rod and the ankle holding device, it is guaranteed that the position of the osteotomy plate is stable enough in the osteotomy operation process, and theaccuracy of osteotomy operation is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an osteotomy positioning device. Background technique [0002] Proximal tibial osteotomy is one of the most important steps in total knee arthroplasty. For different patients, the anatomical structure and degree of wear of the articular surface are different. Therefore, precise osteotomy positioning with tibial osteotomy tools is very important Proximal tibial osteotomy is very important. [0003] Currently, there are two types of tools used for tibial osteotomy positioning: intramedullary positioning and extramedullary positioning. Among them, intramedullary positioning needs to insert a positioning rod into the tibial medullary cavity. Although it can be positioned by the natural anatomical characteristics of the human body, it has the disadvantages of large trauma and bleeding, and it cannot be used in patients with tibial malformations. to use less and less. Extramedulla...
