Abstract: An improved multi-bite bone cutting rongeur with an ultrathin foot plate and a disposable cutting element and storage chamber unit is disclosed. The present invention has an integrated cutting element and storage chamber unit that is truly disposable, rather than merely replaceable. The present invention requires the use of no tools or special assembly. The chamber is simply placed onto the shaft whereby it is immediately locked into place by the use of the instrument.

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.

Abstract: An axial oil filter including at least one pair of axially aligned filter elements includes an elongate filter body and a removable filter cartridge. The filter elements are mounted on an axial conduit which is a part of the filter cartridge, and the filter cartridge placed in the filter body so as to define upper and lower chambers, and a bypass flow path between the upper and lower chambers. Fluid to be filtered may flow into either of the chambers and will flow upward through the lower filter element and downward through the upper filter element. The filtered fluid is collected from a passage defined by a screen between the two filter elements, and passes outward from the filter through the outlet port.
