Abstract

The invention relates to the technical field of medical instruments, in particular to a drill bushing for a sighting device. The drill bushing is used for being installed on a sighting frame. The sighting frame is provided with a drill bushing installation hole which is a through hole. The drill bushing for the sighting device comprises a drill bushing body. The outer ring of the drill bushing body is provided with a tension structure. The drill brushing body is inserted to the drill bushing installation hole through the tension structure on the outer ring of the drill bushing body. The end, entering the drill bushing installation hole at first, of the drill bushing body is the front end of the drill bushing body, the end, entering the drill bushing installation hole later, of the drill bushing body is the rear end of the drilling bushing body, a screw sighting hole is formed in the drill bushing body from the front end to the rear end, and the screw sighting hole is a through hole. According to the drill bushing for the sighting device, a traditional way of fixing a drill bushing and a sighting frame through a clamping spring is changed, the drill bushing and the sighting frame are fixed by arranging the tension structure on the outer ring of the drill bushing body, installation is convenient, and stability is higher when the tension way is adopted.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a drill sleeve for an aimer. Background technique [0002] At present, in the clinical treatment of fractures, congenital dysplasia of bones, or fractures, it is necessary to drive screws into the bones for fixation. Before the screws are inserted, the bones need to be drilled first. Hole needs to use aiming device, aiming device comprises the aiming frame that is fixed on the steel plate, and the drill bushing that is used for guiding is installed on the aiming frame, and the punching device stretches in the drill bushing and punches the bone. The existing drill bushing is plugged into the aiming frame through the retaining spring (the aiming stand is set outside the drill bushing). This installation method has the following defects: 1. The retaining spring is easily deformed and the installation is unstable; 2. The outer ring of the drill bushing and the aiming fram...
