Abstract: A surgical instrument, suitable for endoscopic surgery has a first member and a movably driven second member movable in such first member. One such member comprises a generally tubular proximal member and a tissue working tip which are relatively telescoped and have opposed surfaces. A projection protrudes from such tip surface through such generally tubular member surface to fixedly secure same together.

Abstract: A cutting accessory (20) for use with powered surgical tools. The cutting accessory has a hub (28) for coupling the accessory to the output shaft of a handpiece. A drive shaft (26) formed of stainless steel or other relatively rigid material extends forward from the hub. A head (30) formed from nickel titanium alloy or other metal that is more flexible than the material forming the drive shaft is attached to the distal end of the drive shaft. The head is shaped to form the cutting edges of the cutting accessory. In some versions of the invention, intermediate sections (60) of the drive shaft are formed from the flexible metal or metal alloy.
