Title: SURGICAL HANDPIECE WITH COMPACT CLUTCH AND ANTI-WOBBLE COUPLING HEAD
Abstract:
A surgical handpiece (20) with a rotating spindle (42) for receiving the coupling head (54) of a surgical attachment (320) or a cutting accessory (48). A gear train (36) has plural drive heads (86, 92) that simultaneously rotate at different speeds. A clutch assembly (44) has pins (184) that move along the length of the spindle. The clutch assembly sets the position of the pins so they will engage one of the drive heads . The spindle rotates with the drive head with which the clutch pins are engaged.
