1results about How to "Avoid tunnel splitting" patented technology

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.
