Abstract
A suture anchor system and method including a suture anchor and a suture anchor drive. The suture anchor is positionable on a rod of the suture anchor drive. The rod defines an awl for forming a hole in a bone. The suture anchor drive further has an impactor for moving the suture anchor along the rod between a retracted position and an advanced position so as to implant the suture anchor in the bone with the awl positioned in the bone.
Claims18
A suture anchor drive, comprising:
- a rod having a trailing end adapted to be held and a leading end defining an awl with at least one point for forming a hole in a bone;
- and
- an impactor comprising an impactor sleeve having a front end and a rear end, the impactor sleeve slidably disposed about the rod such that the impactor sleeve is movable axially along the rod between a retracted position wherein the front end of the sleeve is spaced a distance from the leading end of the rod so as to define an anchor holding area on the rod between leading end of the rod and the front end of the impactor sleeve and an advanced position, wherein the impactor sleeve is moved toward the leading end of the rod, and
- wherein the impactor sleeve has an implant alignment protrusion extending in a longitudinal direction into the anchor holding area when the impactor sleeve is in its retracted position and adapted to mate with a corresponding implant alignment notch of a suture anchor such that the suture anchor is substantially prevented from rotating about the longitudinal axis of the rod.

- a suture anchor drive, comprising:
- a rod having a leading end and a trailing end, the leading end defining an awl with at least one point for forming a hole in a bone;
- and
- an impactor comprising an impactor sleeve having a front end and a rear end, the impactor sleeve slidably disposed about the rod such that the impactor sleeve is movable axially along the rod between a retracted position wherein the front end of the impactor sleeve is spaced a distance from the leading end of the rod so as to define an anchor holding area on the rod between the leading end of the rod and the front end of the impactor sleeve and an advanced position wherein the impactor sleeve is moved toward the leading end of the rod, and wherein the impactor sleeve has an implant alignment protrusion extending in a longitudinal direction into the anchor holding area when the impactor sleeve is in its retracted position;
- and
- a suture anchor positioned on the anchor holding area of the rod, the suture anchor comprising:
- a body member having a leading end, a trailing end, a cannula extending through the body member from the leading end to the trailing end, and an outer surface comprising one or more bone engaging members to retain the suture anchor inside a bone, the leading end having at least one suture receiving notch and the trailing end having at least one implant alignment notch formed therein so as to receive the alignment protrusion of the impactor sleeve,
- wherein the suture anchor is positioned on the anchor holding area of the rod with the rod disposed through the cannula of the body member with the awl extending past the leading end of the suture anchor and the implant alignment notch of the trailing end of the body member engaged with the implant alignment protrusion of the impactor sleeve in such a way that axial movement of the impactor sleeve from the retracted position toward the advanced position slides the body member axially along the rod.
