Abstract
The present application is directed to self-locking surgical fasteners. The fastener generally includes a shaft section, a head section, and one or more locking members. The locking members may be located within the head section. A first portion of the locking members may extend beyond an outer surface of the head section, and a second portion of the locking members may extend into a hollow interior of the head section. A tool used to insert the fastener into the patient engages a receiver portion of the fastener. As the insertion tool engages the receiver, the tool may contact and exert a force on the locking member such that the first portion of the locking member may be retracted within the head section. Upon disengaging the insertion tool from the receiver, the locking member may return to the position extending outward beyond the outer surface of the head section.
