Tunnel locator for scapular glenoid tendon

Abstract

The invention discloses a tunnel locator for a scapular glenoid tendon. The tunnel locator comprises an operation cylinder, wherein a locating rod is inserted into an inner cavity of the operation cylinder, the locating rod is parallel to the axial direction of the operation cylinder, a holding rod is fixed to the side wall of the operation cylinder, a distance adjusting lever is vertically inserted into the operation cylinder in the vertical direction through a sliding groove, length scales are arranged on the distance adjusting lever, a rotating ring is arranged at the bottom of the distance adjusting lever, and a locating sleeve is inserted into the rotating ring. According to the tunnel locator, a tunnel entrance and a tunnel exit can be accurately positioned, the distances between a tunnel and the upper wall and the outer side wall of a scapular glenoid can be accurately controlled, complications such as tunnel splitting, iatrogenic fracture and implant fixation failure are avoided, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a locator for a glenoid tendon tunnel. Background technique [0002] In the existing orthopedic surgery, there is a kind of operation that is performed on the scapular glenoid on the scapula of the human body. The front of the neck has important blood vessels and nerve structures such as the brachial plexus, axillary artery, etc. Therefore, the glenoid bone graft surgery does not adopt the method of drilling from the front as much as possible, and the tunnel in the glenoid is still judged by naked eyes. The position of the tunnel cannot accurately locate the entrance and exit of the tunnel, and the distance between the tunnel and the superior and lateral walls of the glenoid cannot be precisely controlled, which may easily cause complications such as tunnel splitting, iatrogenic fractures, and failure of implant fixation. Contents of the invention [0003] The main...
