Abstract
A cutting implement includes a first tubular portion and a second tubular portion. Each tubular portion is hollow and includes a blade element at a distal end. The blade element helps define an aperture that allows access to the interior hollow portion of the tubular portion. A ligament graft element is threaded through the aperture of each tubular portion and the respective tubular portions are interoperated to cut the ligament graft.
Claims10
A surgical instrument comprising:
- a first hollow element comprising a first longitudinal axis, a first distal end and a first handle end, the first distal end comprising a first blade element perpendicular to the fist longitudinal axis;
- and
- a second hollow element comprising a second distal end and a second handle end, the second distal end comprising a blunt edge, the blunt edge perpendicular to the fist longitudinal axis;
- and
- wherein the first hollow element is sized relative to the second hollow element such that the second hollow element telescopingly fits within the first hollow element and is adapted to rotate therewithin in such a manner that rotation of the second hollow element relative to the first hollow element causes the first blade element and the blunt edge to interoperate to cut a workpiece.
