Abstract
A delivery system for attaching and detaching an ultrasonic surgical blade/coupler and an acoustical mount. An adaptor sleeve receives and encapsulates the blade to avoid accidents resulting from the sharp blade edge. A cylindrical member receives the sleeve and a ratcheting mechanism is provided between the adaptor and member to facilitate rotation of the adaptor and coupler upon rotation of the member up to a predetermined torque, ensuring threaded connection between the coupler and acoustical mount sufficient for transmission of ultrasonic energy. To remove the blade/coupler, the member is rotated in the opposite direction, whereby unlimited torque may be applied through the ratchet mechanism to unthread the coupler from the mount.
