Abstract
A surgical instrument includes an instrument body, an ultrasonic transducer assembly, and a slip lock having an arrester. The transducer assembly is rotatably mounted along a longitudinal axis within the body such that the transducer assembly is configured to selectively rotate. The arrester is configured to move relative to the ultrasonic transducer assembly between an engaged position and a disengaged position and has a catch portion and a deflectable portion. The catch portion is configured to seize the transducer assembly and selectively inhibit rotation for rotatably coupling with the acoustic waveguide up to a predetermined torque. The deflectable portion is configured to deflect relative to the transducer assembly upon receiving a torque greater than the predetermined torque. Accordingly, the catch portion releases the transducer assembly to slip relative to the catch portion for limiting coupling of the transducer assembly with the acoustic waveguide to the predetermined torque.
