    Abstract: An apparatus for operating on tissue includes a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body and includes an acoustic waveguide. The waveguide is configured to acoustically couple with an ultrasonic transducer. The end effector includes an ultrasonic blade, a clamp arm, and a clamp pad. The blade is in acoustic communication with the waveguide. The clamp arm is configured to pivot about a first pivot point toward and away from the ultrasonic blade and includes a coupling feature. The clamp pad is selectively attachable to the blade to acoustically isolate the clamp arm from the ultrasonic blade. The coupling feature of the clamp arm is configured to provide a snap fit between the clamp pad and the clamp arm and thereby permit manipulation of the clamp pad for removal of the clamp pad from the clamp arm.

    Abstract: A surgical apparatus comprises a transducer assembly and a shaft assembly. The transducer assembly is operable to convert electrical power into ultrasonic vibrations. The shaft assembly comprises an ultrasonic waveguide, a sheath, a shroud, and a torque transfer assembly. The waveguide is configured to couple with the transducer assembly. The waveguide is disposed within the sheath. The sheath extends through the shroud. The torque transfer assembly is contained within the shroud. The torque transfer assembly is configured to transfer a predetermined range of torque from the shroud to the waveguide to thereby couple the waveguide with the transducer assembly. The torque transfer assembly is further configured to prevent transfer of torque from the shroud to the waveguide beyond an upper limit of the predetermined range.

    Abstract: A surgical instrument can be provided as described herein. The surgical instrument can include a handle with first and second handle portions. One of the first and second housing portions can include a proximal latch and a proximal latch pin. The proximal latch and proximal latch pin can be configured to lock the first and second housing portions together at proximal ends thereof. One of the first and second housing portions can further include a latch projection, a clamp arm, an over center linkage where the latch projection and over center linkage can be configured to lock the surgical instrument in a closed position when the clamp arm is engaged or in an engaged position.
