Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that when the high position osteotomy orthopedic operation of the proximal tibia is performed, there is no special tool, and it is generally blind typed after fluoroscopy, which is prone to deflection. To correct technical defects that lead to low surgical efficiency, thereby providing an osteotomy guide that can improve surgical efficiency

Abstract

The invention provides an osteotomy guiding device. The guiding device includes a frame, a positioning structure, a first guiding sleeve, a positioning pillar and a second guiding sleeve; the frame isprovided with a main rod, a first branch rod and a second branch rod, and an open box bottom of Chinese character; the positioning structure is arranged on the second branch rod and suitable for being positioned at the position of a fibular head; the first guiding sleeve is arranged on the first branch rod and provided with a first center guiding hole, and the central axis of the first center guiding hole passes through the central position of the positioning structure; the positioning pillar rotatably sleeves the first guiding sleeve and is provided with multiple through holes; and the second guiding sleeve is detachably installed in one of the through holes and provided with a second center guiding hole, and the central axis of the first center guiding hole is parallel to the central axis of the second center guiding hole. After an osteotomy position is determined, the guiding device can use the first guiding sleeve and the second guiding sleeve to limit needle inserting positions and needle inserting directions without deflecting, so that high-quality osteotomy can be accomplished for one time, and high surgical efficiency can be achieved.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for orthopedic osteotomy, in particular to an osteotomy guide for auxiliary positioning of high osteotomy at the proximal end of the tibia. Background technique [0002] Patients with genu varus deformity, especially young patients with genu varus with abnormal development of the proximal tibia, need high proximal tibial osteotomy orthopedic surgery when there is only medial knee pain. The treatment mechanism of high proximal tibial osteotomy orthopedic surgery is to transfer the weight-bearing line from the medial compartment of the knee joint where inflammation and wear occurs to the relatively normal lateral compartment through proximal tibial osteotomy, so as to relieve the symptoms of arthritis the goal of. [0003] Specifically, the knee joint with normal line of force usually has more load on the inside and less load on the outside. If there is a certain degree of varus deformity ...
