A bone anchor delivery system device has a retractable punch driver assembly and a bone anchor assembly for attachment onto the punch driver assembly. The punch driver assembly has a retractable punch shaft and a guide for receiving the retractable punch shaft. The punch shaft is linearly movable relative to the guide and the punch shaft having an extended length with bone penetrating tip at a first end. The bone anchor assembly has a bone anchor having a hollow body, a punch, an intermediate lock. The intermediate lock is stowed at a distal end portion inside the hollow body of the bone anchor near a proximal end of the punch and when moved toward a proximal end of the bone anchor the intermediate lock moves inside and expands the hollow body diametrically increasing in size to secure the bone anchor to a bone opening.
