Abstract

A surgical tool system comprising a handpiece and a cutting accessory that is releaseably secured to the handpiece. The handpiece has a gear assembly with two drive heads. The gear assembly turns the drive heads at different rotational speeds relative to each other. The cutting accessory is provided with one of two drive hubs. If the cutting accessory is provided with a first drive hub, the drive hub mates to a first one of the drive heads so as to turn of the speed of that head. If the cutting accessory is provided with a second drive hub, the drive hub mates to the second drive head so as to turn at the speed of that head. Thus, the speed at which the cutting accessory is actuated is a function of the associated drive head.

Claims

1. A surgical handpiece for actuating a cutting accessory, said handpiece having:

a body, said body having a distal end and a proximal end and being shaped to have;

a primary bore adjacent the distal end for receiving a cutting accessory, the bore being defined by an inner wall of said handpiece;

a supply bore that extends from said proximal and that opens into the inner wall of said handpiece that defines the primary bore; and

a suction bore that extends from the primary bore to the proximal end;

a coupling assembly attached to said body for releasably holding the cutting accessory to said body;

a power generating unit in said body adapted for attachment to the cutting accessory to actuate the cutting accessory;

an inlet fitting attached to said body adjacent the proximal end of said body, said inlet fitting being in fluid communication with the supply bore in said body and being configured to be connected to a fluid supply line; and

a suction fitting attached to said body adjacent the proximal end of said body, said suction fitting being in fluid communication with the suction bore in said bore and being configured to be connected to a suction line.
