Sighting device for closed punching of coracoid clavicle

Abstract

The invention discloses a sighting device for closed punching of a coracoid clavicle. The sighting device for closed punching of the coracoid clavicle comprises a guide positioning tube, a positioningring and a connecting device, wherein the positioning ring is fixed at the lower part of the connecting device, the guide positioning tube is inserted in a sleeve at one side of the connecting device, the connecting device is internally provided with a fixing mechanism for fixing the guide positioning tube which passes through the sleeve wall, and the bottom end of the guide positioning tube corresponds to the bottom of the positioning ring. An outer circle of the guide positioning tube is provided with a thread structure. The cavity of the guide positioning tube is hollowed, and the guide positioning tube is formed by two sections of upper and lower tube bodies. The lower tube body is in the threaded connection with the upper tube body. The lower tube body is used for guiding and fixinga kirschner pin, and the upper tube body is used for guiding and fixing a hollowed drill bit. The beneficial effects are that there are only two surgical incisions while the provided sighting device for closed punching of the coracoid clavicle is used in a surgical process, the surgical time is short, the complication is less, the rehabilitation time is shortened, a related medical negligence is completed avoided, and the functional rehabilitation of a surgery patient is good.

Description

technical field [0001] The invention relates to a closed perforation sight, in particular to a close perforation sight on the coracoid clavicle without joint assistance. Background technique [0002] At present, for patients with dislocation of the acromioclavicular joint and fracture of the distal clavicle, traditional treatment methods generally use external fixation with figure-of-eight bandages. However, this fixation method is unstable and often leads to local dislocation and dislocation of deformed appearance. Therefore, distal clavicle hook plate internal fixation is often used in the treatment of acromioclavicular joint and distal clavicle fractures. In this way, the skin needs to be surgically cut to directly expose the dislocation or fracture, and the incision is usually 7-10cm. Due to the effect of the hook plate, patients usually feel pain and discomfort in the shoulder, and it is necessary to remove the plate and screws for a second time after healing. In thi...
