Patent number: 9717550Abstract: An end effector assembly adapted to couple to an electrosurgical instrument, the end effector assembly including a pair of opposing jaw members pivotably attached about a pivot member and moveable from a first spaced position to a second grasping position. Each jaw member includes a jaw housing and a seal plate formed on an inner surface of the jaw member including at least two seal plate segments extending along a substantial portion of the length of the jaw members. An insulating member is positioned between adjacent seal plate segments and configured to provide electrical isolation between adjacent seal plate segments. Each sealing plate segment is adapted to selectively connect to an electrosurgical energy source and form part of an electrosurgical energy delivery circuit.Type: GrantFiled: June 27, 2016Date of Patent: August 1, 2017Assignee: COVIDIEN LPInventors: Glenn A.
