Abstract

According to the tibia osteotomy system and the osteotomy amount adjusting device thereof, the osteotomy amount adjusting device comprises a first rod piece, a second rod piece and an adjusting piece, the first rod piece is provided with a first guide groove, the second rod piece is connected with the first rod piece, the second rod piece is connected with a first shaft, the first shaft is inserted into the first guide groove, and the adjusting piece is connected with a second shaft; the adjusting piece is rotationally connected with the second rod piece through a first shaft, a second guide groove is formed in the adjusting piece, the first rod piece is provided with a second shaft, and when the adjusting piece rotates around the first shaft relative to the first rod piece, the second shaft moves along the second guide groove and gets close to or away from the first shaft; the relative positions of the first rod piece and the second rod piece in the length direction of the first rod piece are adjusted. According to the tibia osteotomy system and the osteotomy amount adjusting device thereof, the second guide groove in the adjusting part is used for restraining the second shaft, so that the second shaft can precisely move relative to the first shaft when moving along the second guide groove, and the osteotomy position can be precisely and finely adjusted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tibial osteotomy system and an osteotomy adjustment device thereof. Background technique [0002] During unicompartmental knee replacement surgery, tibial osteotomy is required to allow proper tibial prosthesis installation. The accuracy of the osteotomy position will directly affect the result of the prosthesis installation. Based on this, in knee replacement surgery, the tibial osteotomy amount fine-tuning device is usually used to fine-tune the height of the tibial osteotomy plate so that the tibial osteotomy plate reaches the optimum position. Proper osteotomy position for precise tibial plateau osteotomy. [0003] The traditional tibial osteotomy amount fine-tuning device is generally threaded fine-tuning type or buckle type (ie, gear type). [0004] Wherein, the thread fine-tuning type is that the upper end rod and the lower end rod are connected together by thr...
