Precise osteotomy guider

Abstract

The invention provides a precise osteotomy guider. The precise osteotomy guider comprises a frame, a positioning structure, a first position determining part, a guide structure and a second position determining part, wherein the frame is provided with a main rod, a first supporting rod capable of sleeving the main rod in a sliding manner and a second supporting rod fixedly connected with one end of the main rod, and the first supporting rod and the second supporting rod are parallel and form a U-shaped structure together with the main rod; the positioning structure is arranged on the first supporting rod and is suitable for being positioned on one side of the fibula; the first position determining part is mounted on the first supporting rod and used for determining the distance between thecenter of the positioning structure and the tibial plateau; the guide structure is arranged on the second support rod and used for guiding the nailing direction of a Kirschner wire to face the centerof the positioning structure; and the second position determining part is mounted on the second supporting rod and used for determining the distance between the center of a guide hole, used for guiding the Kirschner wire, of the guide structure and the tibial plateau. According to the precise osteotomy guider, the osteotomy positions of the outer side and the inner side of the tibial plateau canbe precisely given, it can be guaranteed that the wire inserting direction of the Kirschner wire is accurate, deflection is reduced or avoided, and the osteotomy efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of auxiliary tools for orthopedic osteotomy, in particular to a precise osteotomy guide. Background technique [0002] Patients with knee varus deformity, especially young patients with genus varus with abnormal development of the proximal tibia, need to undergo high-position proximal tibial osteotomy for orthopedic knee joint pain. The treatment mechanism of high proximal tibial osteotomy orthopedic surgery is to use proximal tibial osteotomy to transfer the load-bearing line from the inflammation and wear of the medial compartment of the knee joint to the relatively normal lateral compartment to relieve the symptoms of arthritis the goal of. [0003] Specifically, the knee joint with normal force usually bears more weight on the inside and less weight on the outside. If there is a certain degree of varus deformity in the tibia, it will significantly increase the pressure on the cartilage of the medial compartme...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the technical problem in the prior art that there is no special tool when the high proximal tibial osteotomy orthopedic operation is performed, and the osteotomy is generally directly referred to the head of the fibula, resulting in an inaccurate position of the osteotomy. defects, thereby providing a precise osteotomy guide that can improve the accuracy of osteotomy
