Abstract:
1. A device for use in surgical procedure to anchor a suture to a coiled helical member, said device comprising winding means for winding a suture around the helical member in a helical path such that the suture is attached to at least one turn of the helical member, said winding means including a winding tube rotatable around an axis, said winding tube including securing means for securing at least a portion of the suture thereto so as to cause the suture to wind about the helical member, said securing means including a groove formed in said winding tube that is sized and shaped so as to receive at least a portion of the suture therein, said groove being angled in a direction opposite to the direction of rotation of said winding tube during the winding of the suture around the coiled helical member, said winding tube further including a plurality of first screw threads formed thereon, and a first gear mounted thereon; and a casing that is sized and shaped so as to be gripped by the hand of a surgeon, said casing having a plurality of second screw threads mating with said first screw threads such that said winding tube is mounted to said casing and rotatable relative thereto and movable in an axial direction in response to its rotational movement, a first actuator movably mounted on said casing and adapted for manual activation by a surgeon, and a set of second gears, said first gear being engaged with one of said second gears, said first actuator being engaged with another of said second gears such that said first gear and hence said winding tube are rotatable relative to said casing in response to the movement of said first actuator.
