First Claim
1. A method for supplying a powered handpiece for surgery comprising the steps ofproviding a sterilizable handpiece body having a drive shaft for driving a surgical blade and a motor enclosure compartment, providing a non-sterile motor assembly of a size to be received in the motor enclosure compartment to power the drive shaft and providing a sterile installation device having a passage therethrough of a size to receive the motor assembly;
- sterilizing the handpiece body with the motor assembly removed therefrom;
placing the sterile installation device on the sterilized handpiece body with the passage in communication with the motor enclosure compartment;
introducing the motor assembly through the passage and into the motor enclosure compartment without contaminating the sterilized handpiece body; and

Abstract
A powered handpiece for driving a surgical blade to cut anatomical tissue includes a reusable handpiece body having a distal end for being coupled with a surgical blade, a drive shaft in the handpiece body for rotatably driving the surgical blade, a motor assembly for being installed in the handpiece body to rotatably drive the drive shaft and a suction channel in the handpiece body including a portion extending through the drive shaft parallel to a longitudinal axis of the motor assembly for evacuating anatomical tissue cut by the blade from the handpiece body for external collection. The surgical blade is for use with the powered handpiece and carries a sealing arrangement facilitating irrigation and suction. The handpiece body is capable of being sterilized to medical standards prior to each use. The motor assembly, which is non-sterile, is removable from the handpiece body prior to sterilization of the handpiece body and is reinstallable in the handpiece body subsequent to sterilization of the handpiece body without contaminating the sterilized handpiece body. An installation device includes a reusable funnel for being disposed over the handpiece body and through which the motor assembly is inserted for installation in the handpiece body. An electric cord assembly for being coupled between the handpiece and a power console includes a plug for being plugged into the motor assembly after the motor assembly has been installed in the handpiece body and a locking ring on the plug for selectively, releasably, lockingly engaging the handpiece body to secure the motor assembly in the handpiece body.
