An apparatus includes a body, a shaft assembly, and an end effector. The shaft assembly includes an outer tube, a proximal inner tube member, a distal inner tube member, and an acoustic waveguide. The end effector includes an ultrasonic blade and a clamp arm. A first portion of the clamp arm is pivotably coupled with a distal end of the outer tube. A second portion of the clamp arm is pivotably coupled with a distal end of the distal inner tube member. The outer tube is configured to removably couple with the body and the distal inner tube member is configured to removably couple with the proximal inner tube member such that the outer tube, the distal inner tube member, and the clamp arm are configured to removably couple with the body and the remainder of the shaft assembly and end effector as a unit.
An ultrasonic surgical instrument comprising:
An ultrasonic surgical instrument comprising:
A method of assembling an ultrasonic surgical instrument having a first subassembly and a second subassembly, wherein the first subassembly includes an ultrasonic waveguide, an ultrasonic blade in acoustic communication with the ultrasonic waveguide, a cam surface, a proximal inner tube disposed about a proximal portion of the ultrasonic waveguide, and a proximal outer tube disposed about the proximal inner tube, wherein the second subassembly includes a distal inner tube, a clamp arm is pivotably coupled with the distal inner tube, a snap-fit feature, and a distal outer tube slidably attached to the distal inner tube, wherein the clamp arm is pivotably coupled with the distal outer tube, the method comprising:
