Abstract

The invention discloses a tibia osteotomy positioning system and an ankle mortise working platform and an osteotomy plate fixing platform. The osteotomy plate fixing platform comprises an osteotomy working platform, an osteotomy plate and a laser device, wherein an adjustable angle is formed between the osteotomy plate and the osteotomy working platform, the laser device is arranged on the lower surface of the osteotomy working platform, and the laser device is a laser transmitter or a laser rangefinder. Laser alignment principle and a beam splitter prism are adopted to determine a reclining angle between the working planes of the osteotomy plate and an ankle holding device. The tibia osteotomy positioning system and the osteotomy plate fixing platform and the ankle mortise working platform improve alignment accuracy, simplify operation, improve operation efficiency, and reduce burden of doctors and patients.

Description

technical field [0001] The invention relates to a medical device for osteotomy, in particular to a tibial osteotomy positioning system, an osteotomy plate fixing platform and an ankle hole working platform used in the tibial osteotomy positioning system. Background technique [0002] The tibial osteotomy instrument currently used in knee joint replacement is mainly the tibial osteotomy positioning system, which includes an upper osteotomy plate fixing platform for fixing the tibia for osteotomy, and a lower one for fixing the ankle The ankle point working platform of the joint needs to maintain a fixed backward tilt angle between the osteotomy plate of the osteotomy plate fixing platform and the ankle holding device working plane of the ankle point working platform during use. [0003] In the prior art, the traditional mechanical force line is used to determine the force line of the lower limbs, and the mechanical force line is repeatedly used to determine the reclining angl...
