ABSTRACT:
The suture anchor installation system comprises a suture anchor assembly engaged with a suture anchor insertion tool. The suture anchor assembly features a two-piece suture anchor for insertion into a pre-drilled hole in a bone and at least one suture having at least one surgical needle affixed thereto. The two-piece suture anchor comprises a setting pin slidably engaged within an engagement member having barbed legs expandable in response to proximal movement of the setting pin. The suture anchor insertion tool includes a body portion and a distally extending shaft portion. An annular region of the distal end of the shaft portion engages the legs of the suture anchor engagement member. A channel in the shaft portion aligns with a channel in the body portion to accomodate the suture. Needle-retaining assemblies located on the body portion of the suture anchor insertion tool engage the surgical needle or needles attached to the suture.
