Abstract: 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.

Abstract: An electrosurgical system includes an electrosurgical instrument having an electrode with a polymeric dielectric coating; and an electrosurgical generator, which includes a power converter configured to generate RF energy; a sensor coupled to the power converter and configured to sense a parameter of the RF energy; and a controller coupled to the sensor and the power converter. The controller is configured to control the power converter to output an RF waveform to achieve conductor breakthrough through the polymeric dielectric coating. The controller is further configured to determine whether the conductor breakthrough occurred based on the parameter; and execute a treatment algorithm based on a determination of the conductor breakthrough.

Abstract: A forceps is provided and 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 at least one of 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.

Abstract: A surgical instrument includes an elongated shaft having a distal portion and a proximal portion coupled to a housing. An inner shaft member extends at least partially through the elongated shaft and is selectively movable in a longitudinal direction. An end effector is supported by the distal portion of the elongated shaft. The end effector includes upper and lower jaw members pivotally coupled to the distal portion of the elongated shaft about a pivot axis and including a pair of laterally spaced flanges. The pairs of flanges of the jaw members are arranged in an offset configuration such that one flange of the upper jaw member is positioned on a laterally exterior side of a corresponding flange of the lower jaw member, and the other flange of the upper jaw member is positioned on a laterally interior side of the other flange of the lower jaw member.

Abstract: A surgical instrument includes a housing having an elongated shaft extending distally therefrom and configured to support an end effector assembly at a distal end thereof. The end effector assembly includes first and second jaw members each having a tissue sealing plate disposed thereon and adapted to connect to an electrosurgical energy source for delivery thereto upon activation thereof. A sensor is disposed one or both of the tissue sealing plates of the first and second jaw members and is configured to communicate data relating to a location of tissue disposed between the first and second jaw members to the electrosurgical energy source. The electrosurgical energy source, in turn, uses the tissue location data to adjust one or more parameters associated with the delivery of electrosurgical energy to the tissue upon activation thereof.

Abstract: A jaw member of an electrosurgical instrument includes an insulative spacer including a face and defining first and second elongated recesses on either side of the face, first and second cleats disposed at least partially within the first and second elongated recesses, respectively, a structural frame, and a tissue treating plate. The structural frame is configured to receive at least a portion of the insulative spacer therein such that first and second elongated sides of the structural frame at least partially overlap the first and second cleats, respectively. The first and second elongated sides are engaged with the first and second cleats, respectively, to thereby secure the insulative spacer relative to the structural frame with the face exposed. The tissue treating plate is disposed on the face of the insulative spacer and is adapted to connect to a source of energy to treat tissue therewith.
