Abstract

A minimally invasive and embracing multi-hole osteotomy device, comprising a stopper, on which a collimator for limiting the direction of a drill bit or an oscillating saw is installed, and a slide bar is connected to each end of the stopper in rotation, and the slide bar is correspondingly slidably connected There is a slide rail to adjust the distance and angle between the stopper and the bone. The other end of the slide rail is rotatably connected with a support rod for clamping the bone, and the angle between the stopper and the slide bar is adjusted. The position in the rail, the angle between the slide rail and the support rod, and then change the positional relationship between the sight and the bone, thereby changing the position between the drill bit or the oscillating saw and the bone, so that the drill bit can move the bone at the set position Make a hole, or have the oscillating saw cut through the bone in the set position. Compared with the prior art, the invention is beneficial in that it reduces operation time and patient's pain; the installation process is simple and manpower is saved; bone damage is reduced.

Description

technical field

[0001] The invention belongs to the field of orthopedic medical instruments, in particular to a minimally invasive and embracing porous osteotomy device. Background technique

[0002] In orthopedic surgery, before using an oscillating saw to cut off the femur and tibia, an osteotome needs to be used, and a drill bit is used to make holes through the guiding function of the osteotome. Usually, multiple holes need to be punched to facilitate the oscillating saw to cut off the bone; When the osteotomy is used to drill a hole with the drill, it is necessary to adjust the osteotomy and adjust the position of the drill guide, which reduces the efficiency of the operation, prolongs the operation time, and increases the pain of the patient; in addition, when the osteotomy is installed When using an osteotomy, the installation process is cumbersome and wastes manpower; in the drilling process, in order to cut off with an oscillating saw, an inclined hole is required. ...
