A high tibial osteotomy guide

Abstract

The invention discloses a high tibial osteotomy guider, and belongs to the technical field of medical instruments used in the orthopedics department. The high tibial osteotomy guider is used for grooving for gasket storage in high tibial osteotomy. According to the technical scheme, a cross beam is connected with two horizontal positioning conduits perpendicular to the cross beam. The inner diameter of the positioning conduit is matched with the outer diameter of a Kirschner wire. The upper ends of two parallel guide rails are perpendicularly and fixedly connected with the two ends of the cross beam respectively. The lower ends of the two guide rails are connected through a pull rod. Two sides of a guide plate are in sliding fit with the two guide rails respectively. A horizontal guide hole is formed in the guide plate. The guide hole is a rectangular hole. The upper top face and the lower bottom face, in the guide plate, of the guide hole are parallel oblique planes. The oblique planes incline towards the upper portion of the side, with the positioning conduits, of the plate face. The height of the guide hole is matched with the outer diameter of a drill bit, and a locking screw hole is formed in the side face of each guide rail. The guide hole can guide and restrain the drill bit, so as to make drilling fast, convenient and accurate, efficiency is greatly improved, surgical difficulty is reduced for doctors, and operation time is shortened.

Description

technical field [0001] The invention relates to a guide used in high tibial osteotomy for treating knee osteoarthritis, belonging to the technical field of orthopedic medical devices. Background technique [0002] Knee osteoarthritis is a common senile degenerative disease based on uneven subsidence of the knee joint caused by osteoporosis. The main clinical manifestations include joint pain, deformity, stiffness, and dysfunction. According to the affected parts and scope of knee osteoarthritis, it can be divided into medial compartment type, lateral compartment type, patellofemoral type and total joint type. Among them, medial compartment type accounts for the majority of primary osteoarthritis. 74%. Patients with medial compartment knee osteoarthritis are often accompanied by changes in the alignment of the lower limbs and varus deformity, which seriously affect the quality of life. [0003] The commonly used clinical method is to use high tibial osteotomy to treat knee ...

Problems solved by technology

However, inaccurate or inconsistent drilling angles often occur when drilling holes and connecting long grooves during surgery, and there are also multiple drilling holes that are not aligned up and down, which affects the final shape of the long groove and is not conducive to the placement of gaskets. operate

At the same time, there is no constraint when drilling, and the drilling operation needs to be performed very carefully, which takes a long time and low efficiency

These situations have affected the implementation of the operation and need to be resolved urgently.
