Manual device for precise positioning of bone screw to hold implantation area of scapula of patient to form stop, has hollow guide element allowing passage of wick for forming pre-hole in scapula for inserting anchor to hold bone screw

摘要

The device (1) has a positioning rod (10) including a distal end (11) and a proximal end (12) connected to a handle (13). A target plate (20) is placed at the distal end of the rod. A hollow guide element (30) allows passage of a drilling tool such as a wick, for forming a pre-hole in the scapula of a patient for inserting an anchor to hold a bone screw on the scapula. A curved strip (25) extending from the target plate is supported against the glenoid cavity of the articulation of the shoulder of the patient, where the device is made of biocompatible metal.
