Abstract
A reconstruction system for ligament employing a button/loop construct with a drill pin. The drill pin has a shaft with a proximal and a distal end. A pin tip provided at the distal end of the shaft has a width greater than the shaft diameter. The pin tip helps cut a wider tunnel for fixation of ligaments/grafts in reconstructive surgeries. The shaft of the drill pin is provided with a laser marks for measurement of intraosseous length.
Claims17
A drill pin, comprising:
- a solid shaft extending along a longitudinal axis between a proximal end and a distal end;
- a plurality of laser marks formed on an external surface of the solid shaft;
- a suture eyelet located at the proximal end;
- and
- a pin tip located at the distal end and including a width that is greater than the solid shaft,
- wherein the pin tip gradually widens out and is adapted for cutting a tunnel in bone that is wider than the solid shaft,
- wherein the pin tip is spade-shaped,
- wherein the pin tip includes cutting surfaces that are 180° opposed.
