Abstract
The present invention describes a bio-medically compatible gripping device capable of radial collapse in accordance with the shrinkage of a nylon or other polymeric material cored surgical cable undergoing tension while maintaining a firm grip for prolonged periods of time. It provides a gripping device capable of maintaining a non-damaging hold on the outer surface of a slippery delicate cable under high tension for a sufficient time in which the healing process can occur.
Claims20
A suture anchor comprising:
- a collet having a body having a first end and a second end opposite the first end, the body comprising:
- an outer surface;
- and
- an inner surface, the inner surface defining a channel and having multiple grooves, each of the multiple grooves is spaced about a longitudinal axis of the channel and extends between the first end and the second end;
- and
- wherein the inner surface having the multiple grooves and the outer surface define a radial arrangement of compressive fingers comprising a set of inside fingers and a set of outside fingers, each outside finger of the set of outside fingers is flanked by at least one inside finger of the set of inside fingers.
3 more elements
A tool for deployment of a suture anchor, the tool comprising:
- an upper forked member and a lower forked member, the upper forked member and the lower forked member configured in a scissor-like fashion, the lower forked member is configured to secure and position the suture anchor;
- an auxiliary lever operable to grip a cable associated with the suture anchor, the auxiliary lever comprises a positioning conduit operable to adjust a tension level of the cable;
- and
- a tension retaining member configured to maintain a first level of tension on the cable.
1 more element
A method comprising:
- providing a cable through a channel of a body of a collet, the body having a first end and a second end opposite the first end, the body comprising an outer surface and an inner surface, the inner surface defining the channel and having multiple grooves, each of the multiple grooves spaced about a longitudinal axis of the channel, the inner surface having the multiple grooves and the outer surface define a radial arrangement of compressive fingers comprising a set of inside fingers and a set of outside fingers, each outside finger of the set of outside fingers is flanked by at least one inside finger of the set of inside fingers;
- and
- providing the collet within a channel of a retaining collar such that a first end of the retaining collar is compresses the first end of the body to cause the radial arrangement of compressive fingers to impart radial compression on the cable inserted within the channel of the body.
