Abstract:
1. 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 first longitudinal axis; and a second hollow element comprising a second distal end and a second handle end, the second distal end comprising a second blade element, the second handle end having an exit opening; 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 and second blade elements to interoperate to cut a workpiece, wherein the first blade element at least partially defines a first aperture on the first hollow element such that the workpiece may be threaded through the first aperture; and wherein the second blade element at least partially defines a second aperture on the second hollow element such that the workpiece may be threaded through the second aperture such that the workpiece extends through the second hollow element and extends from the exit opening before interoperation of the first and second blade elements to trim the workpiece, such that the workpiece may be used as a graft.
