ABSTRACT:
An improved rongeur for cutting bone or cartilage comprising two shaft members capable of reciprocating motion relative to each other wherein one shaft member terminates in a foot plate and the other shaft member comprises a combined cutting element and storage member is disclosed. The combined cutting element and storage member has a cutting edge at its distal end and a storage chamber proximate the cutting edge for collecting and storing cut pieces of bone or cartilage in an amount greater than the maximum bone or cartilage capable of being cut in a single full cut. The combined cutting element and storage member is truly disposable, rather than merely replaceable and requires the use of no tools or special assembly. The rongeur may be manually activated or activated by a solenoid and powered by a battery.
