A bipolar electrosurgical instrument for vessel sealing comprises first and second members connected by a pivot. A pair of jaws have opposable seal surfaces that are designed to grasp vascular tissue and conduct bipolar electrosurgical current therethrough. Electrodes on the jaws, including the seal surfaces, are removable and disposable. The jaws of the instrument have mechanical interfaces designed to accept replacement electrodes. The instrument further comprises interlocking ratchets designed to hold a constant closure force between the seal surfaces. Wires extend from the electrodes along one of the members and are connectable to an electrosurgical generator.

1. A bipolar electrosurgical instrument comprising:a pair of first and second members each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof for effecting movement of the jaw members relative to one another; at least one electrode having an electrically conductive seal surface and an insulating substrate, the insulative substrate being overmolded to capture the electrically conductive seal surface; and at least one mechanical interface extending from the insulative substrate which engages a corresponding mechanical interface disposed on one of the jaw members to secure the electrode to the jaw member.
