Abstract
A surgical handpiece assembly for operating a bit having resilient arms to engage the handpiece assembly. The handpiece assembly includes a housing assembly. A drive cannula is coupled to the housing assembly and receives torque from a motor. The drive cannula extends along an axis. The drive cannula has an internal surface defining a bore that extends along the axis. The bore receives the bit. The internal surface has a driving portion to transmit torque to the bit. A retention surface near an end of the drive cannula assists the resilient arms of the bit to retain a position of the bit relative to the drive cannula. A release assembly proximal the drive cannula includes a release member moveable relative to the retention surface to disengage the resilient arms from engagement with the retention surface to permit the bit to move relative to the drive cannula.
