Abstract: A compound motion cutting device for cutting a work piece includes a tubular member having first and second ends, a pair of operating members and a drive rod having first and second ends and extending longitudinally into the tubular member. One of the operating members is secured to the first end of the tubular member and the first end of the drive rod is secured to the other of the operating members. An anvil is supported proximate the second end of the tubular member and includes a surface for supporting the work piece and a slot extending through the support surface. A cutting member includes a first end pivotally attached to the second end of the drive rod and a cam slot extending laterally therethrough. A pin is supported proximate the second end of the tubular member an extends through the cam slot in the cutting member.

Abstract: A method and a tool for tying a stitch knot. The tool comprises a first elongated member and a grasping member. The first elongated member includes a helix on one end. The helix has a filament extending from the first end, and a threading device is attached to the free end of the filament. The grasping member is separate and apart from the first elongated member, and includes an elongated shaft. A grasper is mounted on the first end of the shaft, and a portion of the shaft near the grasper is sized to reside within the helix for axial movement therewith. The method for tying the stitch knot involves positioning the shaft within the helix. The grasper is used to insert the threading device and pull the free end of the filament through an area to be stitched, and then to grasp the free end of the filament near the threading device. The grasping member is removed from the inner space of the helix, thus drawing the free end of the filament through the helix.
