Spinal Implant Clearing Gouge
First Claim
1. A gouge for clearing bone and soft tissue from about a rod which has been previously implanted within a human being, the gouge comprising:
- an elongate handle at a proximal end;
a cutting member at a distal end; and
the cutting member having a rod capture arm having an arcuate surface generally conforming to the cylindrical shape of the rod, and a curved leading cutting blade extending over the rod capture arm;
such that when the rod capture arm is placed in contact with the rod and rotated about such rod toward the curved leading cutting blade the cutting blade will cut away any bone and soft tissue adjacent the rod.

Abstract
A surgical gouge for clearing bone and soft tissue from around a previously implanted rod during a surgical operation. The gouge includes an elongate handle with a distally positioned cutting member at one end. The cutting member has a rod capture arm with an arcuate surface generally conforming to the cylindrical shape of the rod. The cutting member further having a curved leading cutting blade extending over and about the rod capture arm. The curved leading cutting blade configured so as to create a trough between the inside surface of the curved leading cutting blade and the rod capture arm to capture any cut bone and/or soft tissue from around the rod as the gouge is rotated about the rod. The curved cutting blade having a distal end sharpened at its distal edge to enable the user to cut away bone and soft tissue from around the rod. It may also be desirable for the distal end to have sharpened side edges to assist in cutting away the bone and soft tissue that have built up about the rod.

9. A gouge for clearing bone and soft tissue from about a rod which has been previously implanted within a human being, the gouge comprising:
-
an elongate handle at a proximal end; a cutting member at a distal end; the cutting member having a rod capture arm having an arcuate surface generally conforming to the cylindrical shape of the rod, and a curved leading cutting blade extending over the rod capture arm, the curved leading cutting blade having an inside surface facing said rod capture arm; and a trough being created between said inside surface of the curved leading cutting blade and the rod capture arm; such that when the rod capture arm is placed in contact with the rod and rotated about such rod toward the curved leading cutting blade the cutting blade will cut away any bone and soft tissue adjacent the rod, such bone and soft tissue being captured within said trough for easy removal from the surgical site. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of removing bone and soft tissue from about an implanted rod within a human body, comprising:
-
providing a gouge having an elongate handle and a cutting member at a distal end, the cutting member having a rod capture arm having an arcuate surface generally conforming to the cylindrical shape of the rod, and a curved leading cutting blade extending over the rod capture arm; and placing the arcuate surface of the rod capture arm onto the rod with the distal end of the curved leading cutting blade adjacent the bone and soft tissue to be removed from about the rod; and rotating the gouge in a direction towards the distal end of the curved leading cutting blade with the arcuate surface of the rod capture arm bearing on the rod so that the curved leading cutting blade will cut an arcuate path into the bone and soft tissue surrounding the rod. - View Dependent Claims (17, 18)
