Abstract:
A laparoscopic surgical cutting tool has a handle attached to a hollow tube. A tube end segment is pivotally attached to the tube. A linkage connects the handle to the end segment to allow the surgeon to adjust the angle between the end segment and tube, using the handle. A step projects upwardly at an angle at the distal end of the end segment. A lip attached to the end segment extends in a plane generally parallel to the axis of the end segment. Electrifiable cutting wires extend from an upper inside surface of the end segment to the lip.
