Abstract
A rasp tool comprises a handle and a cutter. The handle carries a releasable locking assembly to couple the cutter to the handle and the releasable locking assembly is compactly arranged at one end of the handle via a transversely extending flange which also acts as a spacer between the releasable locking assembly and the roughened outer surface of the cutter.
Claims14
A rasp tool for contouring a bone or the like comprising a handle with a head at one end and a releasable locking assembly at the other end, a cutter cooperating with the releasable locking assembly and adapted to contour the bone, the other end including a transversely extending flange defining a pair of oppositely facing surfaces, the cutter engaging one of the surfaces when cooperating with the releasable locking assembly and the releasable locking assembly extending away from the other surface and defining a length which is substantially less than a length for the handle, the flange defining an aperture for receiving a portion of the cutter and the portion extends into the releasable locking assembly to cooperate therewith, and the releasable locking assembly is carried by the flange on one side of the latter to remain spaced from all of the cutter except for that portion of the cutter extending into the aperture.
A rasp tool for contouring a bone comprising a handle with a head at one end and a releasable locking assembly at the other end, a rasp element cooperating with the releasable locking assembly and adapted to contour the bone, the other end of the handle defining a transversely extending flange to substantially dispose the releasable locking assembly on one side of the flange, the flange defining an opening for receiving a stem portion of the rasp element and the stem portion extending through the flange opening to cooperate with the releasable locking assembly solely on the one side of the flange, and the remaining portion of the rasp element is disposed on the other side of the flange.
A rasp tool for contouring a bone comprising a handle with a head at one end and a releasable locking assembly at the other end, a rasp element cooperating with the releasable locking assembly for selective attachment to an separation from the handle, the other end of the handle including a transversely extending flange with a pair of oppositely facing surfaces, the rasp element extending outwardly from one of the surfaces when attached to the handle, the releasable locking assembly extending outwardly from the other surface and the handle intersects the flange on the other surface for connection therewith at a location transversely disposed from the releasable locking assembly whereby the handle and releasable locking assembly extend outwardly from the other surface substantially in the same direction.
