Abstract
A bone rasp for preparing the medullary canal of the femur includes a rasp blade portion shaped and tapered so as to conform to the medullary canal and a handle portion which is designed to be manually attached to the rasp blade and detached from the rasp blade for sterilizing and storing. The handle portion is arranged into two components which are pivotally connected and pinned together. The stationary portion of the handle attaches directly to the rasp blade and the movable or adjustable portion is pinned to the stationary portion at a pivoting location and secured in a selected orientation by a second pin. A series of seven oblong slots are disposed in the stationary portion and arranged on 71/2.degree. intervals so as to give the adjustable portion of the handle an approximate 45.degree. range of adjustment. The adjustable handle portion is configured with the stationary portion such that the lower end of the adjustable handle portion contacts and pivots directly against a concave surface so that all mallet forces directed to the adjustable handle portion are transmitted to the stationary portion and not to either the pivot pin or the securing pin.
