Abstract
A tissue fixation system is provided for dynamic and rigid fixation of tissue. A fastener connected with an elongate fastening member, such as a cable, wire, suture, rod, or tube, is moved through a passage between opposite sides of tissue. A medical device is used to secure the fastener to the elongate fastening member. The medical device includes a tensioning mechanism for tensioning the elongate fastening member. As crimping mechanism is used to secure the fastener to the elongated member, where a cutting mechanism cut the excess portion of the elongated member.
Claims24
A method of tensioning an elongate member, the method comprising:
- looping the elongate member through a graft, wherein the graft is configured to be secured to at least one of a first tissue and a bone;
- passing at least one end of the elongate member through at least one of a second tissue and bone;
- providing a cannulated tensioning device comprising:
- a cannulated tube, having a proximal end and a distal end, and defining a longitudinal passage along a central longitudinal axis;
- a handle attached to the proximal end of the cannulated tube, wherein the handle is configured to allow the elongate member to pass through at least a portion of the cannulated tube and the handle;
- and
- a tensioning mechanism disposed on the handle of the tensioning device, the tensioning mechanism comprising:
- a rotation assembly;
- at least one biasing member configured to apply a tension force to the elongate member;
- and
- a rotatable shaft positioned along an axis perpendicular to and intersecting the axis defined by the longitudinal passage of the cannulated tube, the rotatable shaft having an open end slotted aperture;
- advancing the at least one end of the elongate member through the cannulated suture tensioning device;
- capturing and securing the elongate member in the slotted aperture of the rotatable shaft of the tensioning mechanism;
- and
- rotating the rotation assembly of the tensioning mechanism to apply tension to the elongate member as the rotation assembly wraps the elongate member around the rotatable shaft, thereby tightening the elongate member and tensioning the graft.
A method of tensioning an elongate member, the method comprising:
- securing the elongate member to at least one of a tissue, bone, graft, anchor, and implant;
- providing a cannulated tensioning device comprising:
- a cannulated tube, having a proximal end and a distal end, and defining a longitudinal passage along a central longitudinal axis;
- a handle attached to the proximal end of the cannulated tube, wherein the handle is configured to allow the elongate member to pass through at least a portion of the cannulated tube and the handle;
- and
- a tensioning mechanism disposed on the handle of the tensioning device, the tensioning mechanism comprising:
- a rotation assembly;
- at least one biasing member configured to apply a tension force to the elongate member;
- and
- a rotatable shaft positioned along an axis perpendicular to and intersecting the axis defined by the longitudinal passage of the cannulated tube, the rotatable shaft having an open end slotted aperture;
- advancing the at least one end of the elongate member through the cannulated suture tensioning device;
- capturing and securing the elongate member in the slotted aperture of the rotatable shaft of the tensioning mechanism;
- and
- rotating the rotation assembly of the tensioning mechanism to apply tension to the elongate member as the rotation assembly wraps the elongate member around the rotatable shaft, thereby tightening the elongate member against the at least one of a tissue, bone, graft, anchor, and implant.
