Flat suture anchor

摘要

A suture anchor for anchoring a suture to a bone, including a distal end having a bifurcated tip, in which the bifurcated tip defines a suture-engaging slot, a proximal end, a longitudinal axis between the distal end and the proximal end, and two substantially flat surfaces extending between the distal end and the proximal end, in which the two substantially flat surfaces are substantially parallel, in which the two substantially flat surfaces are separated by a thickness of no more than about 0.1 inches, and in which the two substantially flat surfaces extend along an axis perpendicular to the longitudinal axis by a width of no more than about 0.4 inches.

1. A method of inserting a suture anchor, comprising:
mechanically engaging at least one suture with a suture anchor, the suture anchor comprising:
a distal end having a bifurcated tip, wherein the bifurcated tip defines a suture-engaging slot;a proximal end including a driving surface configured to receive an insertion force along a longitudinal axis from a driver rod of an insertion tool, wherein the longitudinal axis extends between the distal end and the proximal end;two substantially flat surfaces extending between the distal end and the proximal end, wherein the two substantially flat surfaces are substantially parallel, wherein the two substantially flat surfaces are separated by a thickness of no more than about 0.1 inches, wherein the two substantially flat surfaces extend along an axis perpendicular to the longitudinal axis by a width of no more than about 0.4 inches and wherein each of the substantially flat surfaces is symmetrical with respect to the longitudinal axis;a transverse opening between the two substantially flat surfaces, the transverse opening configured for holding the at least one suture;two exterior edges extending along the longitudinal axis and defined by the thickness; anda plurality of retention barbs defined by at least a portion of each of the two exterior edges located proximally of the transverse opening; and inserting the suture anchor into a bone.
