Abstract
The present invention discloses a rongeur type bone and cartilage removal device incorporating first and second pivotally secured handles, the first handle terminating at a forward end in a first jaw exhibiting a plurality of extending teeth, with second handle terminating in a second jaw opposing the first jaw and exhibiting a continuous blade edge against which the teeth seats during pivotal motion of the jaws.
Claims11
A rongeur type bone removal device, comprising:
- first and second pivotally secured handles, said first handle terminating at a forward end in a first jaw exhibiting a plurality of extending teeth, said second handle terminating in a second jaw opposing said first jaw and exhibiting a continuous blade edge against which said teeth seats during pivotal motion of said jaws in order to successively excise increments of bone for evacuation through said passageway and into said collection chamber.
A rongeur type bone removal device, comprising:
- first and second pivotally secured handles contoured along rear extending grasping portions, each of said handles including a forward circular and overlapping portion;
- said first handle terminating forwardly of its overlapping portion in an integrally formed upper jaw exhibiting an elongated depth defining and downwardly open profile integrating a continuous plurality of alligator type gnawing teeth;
- said second handle terminating forwardly of its overlapping portion in an upwardly open facing and depth defining lower jaw aligning with said teeth of said upper jaw, said lower jaw exhibiting an upper continuous blade edge which matches said profile of said downwardly facing teeth so that that, upon positioning said jaws on opposite sides of a section of bone to be removed, inward opposing compression applied to said handles results in said jaws pivoting together so that said teeth abut said continuous blade edge concurrent with a volume of bone being excised and deposited within an interior chamber defined in said lower jaw.
