Patent number: 11020171Abstract: Electrosurgical instruments with passive articulation and thermal insulation are described herein. Such instruments can provide the advantages associated with passive articulation while protecting tissue and other structures from unintentional thermal damage when an end effector is pressed thereagainst to effect articulation while at an elevated temperature due to use. In one embodiment, such an instrument can include a distal end effector with jaws to clamp tissue, a proximal actuating portion, an energy delivery surface that contacts grasped tissue, and a passive articulating portion disposed between the end effector and the actuating portion. The articulating portion can be configured to selectively permit movement of the end effector relative to the actuating portion in response to external forces acting on the end effector. Further, an outward-facing surface of at least one of the first and second jaws can be covered in a thermally insulating material.Type: GrantFiled: February 1, 2017Date of Patent: June 1, 2021Assignee: Ethicon LLCInventor: Barry Worrell
