Abstract
Abstract An instrument for applying an orthopedic fastener activated by a setting pin includes a member for abutting the fastener, a member for grasping the setting pin, and means for moving said members relative to each other. The instrument may be used endoscopically in conjunction with a cannula. An endoscopic drilling member is provided for deployment through the cannula to create a hole for emplacement of the fastener into bone or hard tissue.
