Multi-circuit seal plates

摘要

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.

1. An end effector assembly comprising:
a pair of opposing jaw members pivotably attached and moveable from a first spaced position to a second grasping position, each jaw member including:
a jaw housing;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 a length of the jaw members;an insulating member positioned between adjacent seal plate segments and configured to provide electrical isolation between the adjacent seal plate segments; anda seal plate mount configured to operably couple the seal plate and the jaw housing and further configured to electrically couple each of the at least two seal plate segments to an electrosurgical energy source, wherein the seal plate mount includes at least one switch circuit board disposed on and operably coupled atop the seal plate, and wherein each seal plate segment is adapted to selectively connect to the electrosurgical energy source and form part of an electrosurgical energy delivery circuit.
