Electrosurgical system with jaws and with means for imparting mechanical perturbations to a jaw

摘要

An end effector assembly (300) for use with an electrosurgical instrument is provided. The end effector assembly includes a pair of opposing jaw members (310, 320) configured to grasp tissue (301) therebetween, at least one jaw member adapted to connect to a source of electrosurgical energy (500) to seal tissue disposed between jaw members during a sealing process. At least one of the jaw members includes an activator (305) configured to selectively impart mechanical perturbations to the at least one jaw member during the sealing process.
