TISSUE AND BONE GRAFT REMOVAL DEVICE

摘要

The present invention discloses a rongeur type bone and cartilage removal device incorporating a pistol shaped body exhibiting a forward extending barrel terminating in a powered saw drive including a plurality of blades. A passageway extends through an interior of the barrel and communicates the forward chain drive with a rearward positioned debris collection chamber. A power supply is incorporated into the body and, upon actuating a trigger, closes a circuit with the saw drive and a separate vacuum inducing drive in order to successively excise increments of bone for evacuation through the passageway and into the collection chamber. Another variant of the rongeur type bone removal device includes 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.
