Patent ID: 7572260

Claim:
An orthopedic bone rasp device for complete planing of the end surfaces of a pair of bones that are joined together by a fixation pin are made parallel, planar, and congruous to each other in preparation for their fusion together, comprising: an elongated shank for removable attachment to a reciprocating power tool; a pair of legs extending from and integrally attached to the shank with the legs being spaced from each other; the legs including a smooth surface and an opposite working side with the working side including an abrasive surface that is dimensioned for acting upon a substantially large percentage of the substrate area of the end surfaces of the pairs of bones with the working side contoured to avoid marginal and peripheral splintering of the end surfaces of the bones; each leg including an inner convex surface of variable radius shaped and oriented at an angle that is not perpendicular to the adjacent abrasive and smooth surfaces and the inner convex surfaces being disposed in a parallel orientation with respect to each other; the inner convex surfaces being spaced from each other for defining a slot; and whereupon the slot slides on the fixation pin with the fixation pin being accommodated within the slot defined by the inner convex surfaces of the legs so that the legs are located on opposite sides of the fixation pin with the legs capable of rotating at least 180 degrees about the fixation pin and capable of toggling and laterally pivoting on the fixation pin at various degrees of obliquity relative to the axis of the fixation pin for reciprocally and simultaneously planing the entire end surface of each bone on both sides of the fixation pin so that the end surfaces of both bones are made congruently planar and parallel to each other and able to be brought into complete apposition in preparation for the fusion together of the end surfaces of the bones.
