Epiphyseal plate bone bridge removing device

Abstract

The invention discloses an epiphyseal plate bone bridge removing device. The device comprises an operation part, an insertion part, a bent part, a front end part, a light guide hose, a light guide plug rod part, a drill bit, a lens, a light hole, a universal flexible shaft, an angle steel wire, a light guide bundle, an image guide bundle, an angle knob and an electric hand drill, wherein the frontend of the operation part is sequentially connected with the insertion part, the bent part and the front end part; the drill bit, the lens and the light hole are arranged on / in the end face of the front end part; the light guide hose and the angle knob are arranged on the side surface of the operation part; the detachable electric hand drill is arranged at the rear end of the operation part; andthe universal flexible shaft, the angle steel wire, the light guide bundle and the image guide bundle are arranged in the insertion part. The design principle of the epiphyseal plate bone bridge removing device is similar to that of a gastrointestinal endoscope, namely an instrument is carried by the insertion part to enter the body to operate a focus part, integrated combination of direct visionand surgical operation is achieved, and the angle of the lens and the angle of the drill bit can be flexibly adjusted during operation, so that the epiphyseal plate bone bridge is effectively and accurately removed.

Description

technical field [0001] The invention belongs to the technical field of medical orthopedic tools, in particular to an epiphyseal plate bone bridge removal device. Background technique [0002] The epiphyseal plate is the active cartilage area between the epiphysis and the metaphysis of children. It has the function of vertical and horizontal growth. Fractures, infections, tumors, and radiation can cause damage to the epiphyseal plate. After the epiphyseal plate is injured, a bony connection, that is, a bone bridge, may be formed in the cartilage area between the epiphysis and the metaphysis, so that all or part of the epiphyseal plate is closed in advance, resulting in limb shortening and / or angular deformity. To prevent later deformity or reduce existing deformity progression, epiphyseal bone bridge resection is an alternative and effective method. The surgical resection methods for the formation of bone bridges after epiphyseal plate injury in children are mainly open surg...

Problems solved by technology

Due to the high requirements for fluoroscopy, it is inevitable that there will be problems such as difficult positioning, insufficient bone bridge resection, excessive resection, and the need for a large number of X-ray irradiation for both the operator and the child.

When the bone bridge of the epiphyseal plate is central or the position is scattered irregularly, it is difficult to accurately judge the position of the bone bridge by two-dimensional images, and the line of sight is blocked, and the epiphyseal plate cannot be seen directly, which may easily lead to incomplete grinding or accidental damage to the normal epiphysis plate

Intraoperative 3D CT navigation technology can be applied in the field of pediatric orthopedics to resection of the epiphyseal plate bone bridge, with accurate in vitro positioning, but the steps of navigation technology are cumbersome, the operation time is long, the economic cost is high, the operator has high requirements, and it takes a period of time to learn curve to master
