Ultrasonic treatment devices

Abstract

Ultrasonic treatment device includes a blade configured to apply ultrasonic vibrations to target tissue and a jaw movable relative to the blade between open and closed configurations. In some examples, the jaw includes a base having an inner channel and a plurality of slots in communication with the inner channel, and a pad having a plurality of protrusions, each protrusion configured to be received within a different slot of the plurality of slots. In further examples, the jaw includes a base having a pair of side walls defining an inner channel, one of the side walls including a rail member extending into the channel, and a pad having a single groove for receiving the rail member when the pad is positioned within the channel. A surface of the groove is configured to contact a surface of the rail when a force is applied against a grasping surface of the pad.
