Suture anchor installation system.

摘要

The suture anchor installation system comprises a suture anchor assembly (100) engaged with a suture anchor insertion tool (200). The suture anchor assembly features a two-piece suture anchor for insertion into a pre-drilled hole in bone and at least one suture (101) having at least one surgical needle (400) affixed thereto. The two-piece suture anchor comprises a setting pin (110) slidable engaged within an engagement member (120) having barbed legs expandable in response to proximal movement of the setting pin. The suture anchor insertion tool (200) includes a body portion (210) and a distally extending shaft portion (240). An annular region (244) on the distal end of the shaft portion engages the legs of the suture anchor engagement member. A channel (242) in the shaft portion aligns with a channel (212) in the body portion to accommodate the suture. Needle-retaining assemblies (220) located on the body portion of the suture anchor insertion tool engage the surgical needle or needles attached to the suture. <IMAGE>
