Abstract
Apparatus and method is provided for shaping bone, in which, individually or together, a gaseous fluid such as air is delivered along the shaping member to impinge upon aerosols created by the shaping of the bone and to deliver the aerosols back toward the bone away from an operator, and a cooling liquid is delivered along the shaping member, in order to cool the shaping member where it contacts the bone. Preferably, the gaseous fluid is air and it is delivered through a manifold carried by the shaping member, forming an air curtain. Preferably, the cooling liquid is at least partially water, with or without a curative substance carried therein, with the liquid preferably being delivered through the shaping member and opening in a direction toward the shaped bone. Where the shaping member is a saw, the liquid may be delivered through the interior of the saw, for discharge through at least one narrow side thereof. Alternatively, the cooling liquid may be delivered externally of the saw. Various refinements are also provided in the form of valves, deflectors and means for exhausting heat and/or cut-away material from the site of operation.
