摘要：
A bone anchor delivery system device (10) has a retractable punch driver assembly and a locking mechanism (32). The punch driver assembly has a retractable punch shaft (30) and a guide (20) for receiving the retractable punch shaft (30). The guide (20) is rotatable relative to the punch shaft (30) and the shaft has an extended length with bone penetrating tip (35) at a first end (33). The locking mechanism (32) for locking the retractable punch shaft (30) from linear movement and rotational movement relative to the guide (20) is positioned at an opposite second end. The retractable punch shaft (30) has a reduced diameter end (33) extending from the tip (35) toward a shoulder stop for receiving a releasable punch (12). The releasable punch (12) has a hollow opening for receiving the reduced diameter end (33) of the punch shaft (30). The punch (12) is profiled to pierce and form a bone anchor hole.
