Abstract

The invention provides a tibia osteotomy extramedullary and intramedullary multifunctional positioning system. The tibia osteotomy extramedullary and intramedullary multifunctional positioning systemcomprises a main body mechanism, wherein an ankle holding device is arranged at the bottom of the main body mechanism, an ankle joint can be held by the ankle holding device, an extramedullary positioning mechanism capable of moving and rotating in the axial direction of the main body mechanism is arranged on the main body mechanism, and the extramedullary positioning mechanism can be positioned on osteotomy extramedullary parts. An intramedullary positioning mechanism capable of moving in the radial direction and rotating in the axial direction of the main body mechanism is arranged on the main body mechanism and can be positioned in osteotomy intramedullary parts. The intramedullary positioning mechanism and the extramedullary positioning mechanism are integrated on the main body mechanism to form a set of positioning system, during tibia osteotomy positioning, intramedullary measurement and extramedullary measurement can be realized only by utilizing the positioning system disclosedby the embodiment, other tools do not need to be replaced, the operation is simple, the surgery time is shortened, the surgery precision and the surgery completion effect are improved, and the positioning is accurate.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for artificial joint surgery, in particular to a tibial osteotomy extramedullary and intramedullary multifunctional positioning system. Background technique [0002] The tibial osteotomy positioning measurement system is an auxiliary tool for tibial resection during the initial operation of the knee joint. The existing tibial osteotomy positioning measurement system is extramedullary positioning or intramedullary positioning. There are two independent positioning systems. Doctors can only operate according to The operation of the pre-prepared positioning system is complicated and there are no more options, resulting in a long operation time and affecting the accuracy of the operation and the effect of the operation. Contents of the invention [0003] The present invention provides a tibial osteotomy extramedullary and intramedullary multifunctional positioning system. The existing positi...
