A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.

Surgical forceps

A forceps includes an end effector assembly having a stop and a plurality of overmold teeth within at least one jaw member. One (or both) of the jaw members is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. One (or both) of the jaw members includes a stop molded within an insulative housing, and an insulator plate with the overmold teeth formed from plastic. The overmold teeth extend through openings within a sealing plate and protrude past the tissue sealing surface of the sealing plate. The stop primarily controls the gap distance between opposing jaw members by bearing most of an applied load and the overmold teeth assist in controlling the gap distance by bearing the remaining applied load.

Gap control via overmold teeth and hard stops

A forceps includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

Apparatus for performing an electrosurgical procedure

A method for manufacturing an electrode configuration configured for use with an electrosurgical instrument is provided. A pre-assembled jaw configuration including jaw members including respective first and second electrodes is provided. One or more stop members are positioned on the first electrode. The first and second electrodes are approximated toward one another for contact therebetween so as to form an at least one indentation on the second electrode.

Method for manufacturing an electrode assembly configured for use with an electrosurgical instrument

A bipolar electrosurgical instrument is provided. The bipolar electrosurgical instrument includes first and second shafts 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. A first conductive lead is adapted to connect to a first electrical potential and a second conductive lead is adapted to connect to a second electrical potential. One of the first and second conductive leads extends through the pivot to connect to a respective jaw member.
