Surgical rongeur
First Claim
1. A surgical rongeur for cutting bone or tissue comprising:
- an elongated track member having proximal and distal ends, the distal end terminating in a foot plate;
an elongated cutting slide in a sliding arrangement with the elongated track member, the cutting slide having proximal and distal ends, first and second sides, and top and bottom surfaces defining an inner cavity, the distal end of the cutting slide defining a sharp cutting edge and an opening through which access is granted to the inner cavity, wherein the cutting slide is removably received within the elongated track member such that the sharp cutting edge may engage the foot plate; and
means for slidably moving the cutting slide longitudinally relative to the elongated track member.

Abstract
A surgical rongeur for cutting bone or tissue is provided. The rongeur has an elongated track member, and a generally hollow cutting slide defining an inner cavity slidably received within the track member. The distal end of the cutting slide terminates in a sharp cutting edge and an opening. The distal end of the track member terminates in a foot plate. The cutting slide is longitudinally movable relative to the track member from a first open position to a second closed position. In the first open position, there is an opening between the sharp cutting edge and the foot plate, in which opening the bone to be cut is placed. In the second closed position the sharp cutting edge contacts the foot plate, cuts the bone and pushes the bone chip through the opening into the inner cavity of the cutting slide, where multiple bone chips may be stored.

18. A surgical rongeur for cutting bone or tissue comprising:
-
an elongated track member having proximal and distal ends, the distal end terminating in a foot plate, the proximal end terminating in a support handle having top and bottom ends and extending downwardly from the track member, the elongated track member further comprising a track extending substantially the length of the elongated track member;
an elongated cutting slide in a sliding arrangement with the elongated track member, the cutting slide having proximal and distal ends, first and second sides, and top and bottom surfaces defining an inner cavity, the distal end of the cutting slide defining a sharp cutting edge and an opening through which access is granted to the inner cavity, wherein the cutting slide is removably received within the elongated track member such that the sharp cutting edge may engage the foot plate, the cutting slide further comprising at least one track engaging protrusion extending downwardly from the bottom surface of the cutting slide for engaging the track of the elongated track member;
a pivot handle having top and bottom ends extending downwardly from the elongated track member;
means for pivotally attaching the pivot handle to the support handle; and
means for removably attaching the pivot handle to the proximal end of the cutting slide;
wherein manipulation of the pivot handle slidably moves the cutting slide longitudinally relative to the track member from a first open position in which the sharp cutting edge of the cutting slide is positioned proximal the foot plate defining an opening between the sharp cutting edge and the foot plate, and a second closed position in which the sharp cutting edge is in contact with the foot plate. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 32)
