    Abstract: 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.

    Abstract: Surgical instruments of the invention are provided with distal ends having a clevis (20) and two discrete investment cast end effectors (90, 92). One end effector (92) is stationary relative to the clevis, and the other moves or rotates about a transverse pin (45) of the clevis. The rotating end effector (90) includes a first hole through which the transverse pin extends, and the surgical instrument includes an actuation mechanism for causing the rotating end effector to rotate about the transverse pin. The actuation mechanism preferably includes a push rod (60) which is either directly coupled to the proximal end of the rotating end effector or coupled by a link element (97). On the other hand, the stationary second end effector, while including a first hole through which the transverse pin extends, has a boss (46) which preferably engages a hole (46') in the clevis and is not coupled to the actuation mechanism. With the clevis and second end effector being coupled at two locations, the second end effector is not free to rotate about the clevis pin, but is held stationary. Other manners of holding the second end effector stationary are to provide the clevis with a boss, and the stationary end effector with a second hole into which the boss extends, or to provide another pin which extends through one arm of the clevis and the stationary end effector only.

    Abstract: An electrosurgical instrument (10) includes a first arm (20), a second arm (22) and a coupling system. The first arm includes a first jaw (30). The second arm is pivotably connected to the first arm and includes a second jaw (38), a cutting member (18) movable within the first and second jaws and a cutting member trigger (16). The coupling system includes a coupling member (118) mechanically coupled to the cutting member trigger. The coupling member is movable between a first position and a second position. Only in the second one of these two positions of the coupling member does movement of the cutting member trigger cause distal advancement of the cutting member.
