Abstract: An assembly tool for facilitating assembly of a surgical instrument includes a handle, a neck extending from the handle, and a portion of or an entire pivot pin engaged with the neck via a frangible connection. The pivot pin is engagable with the surgical instrument. The frangible connection is configured to break upon application of stress thereto above a threshold, thereby separating the pivot pin (or portion thereof) from the neck. A method of assembling using such an assembly tool includes positioning a component of a surgical instrument for receipt of a pivot pin, manipulating the assembly tool to operably engage the pivot pin with the component, and manipulating the assembly tool to apply stress to the frangible connection to break-off the pivot pin (or portion thereof) from the assembly tool along the frangible connection.

Abstract: A method of manufacturing a jaw member of an end-effector assembly includes forming one or more stress-relief cavities within a sealing plate. Each one of the one or more stress-relief cavities defines a pad portion of an electrically-conductive surface of the sealing plate. The method also includes forming a stop member on each pad portion of the electrically-conductive surface of the sealing plate, performing an overmolding operation wherein the one or more stress-relief cavities is configured to prevent force applied to a bottom surface of the sealing plate during the overmolding operation from stressing each pad portion to avoid compromising adhesion between the stop member and the electrically-conductive surface of the sealing plate.

Abstract: A surgical instrument is provided. The surgical instrument includes a housing. A movable handle is coupled to the housing and is configured to approximate a pair of jaw members toward and away from one another. A latch mechanism operably couples to the movable handle and includes one or more mechanical interfaces configured to selectively engage a corresponding mechanical interface disposed within the housing to lock and unlock the jaw members in an approximated configuration. When the movable handle is in a jammed position, the mechanical interface(s) of the latch mechanism is/are configured to deform and separate from the corresponding mechanical interface disposed within the housing when the movable handle is moved from the jammed position.

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: An electrosurgical instrument includes a housing including an elongated shaft. A stationary actuation member is axially disposed within the elongated shaft and includes a cam pin. An actuating mechanism is operably coupled to the elongated shaft and is moveable relative to the housing to selectively cause movement of the elongated shaft. An end effector includes a pair of opposing first and second jaw members operably coupled about a common pivot. One or both of the jaw members includes a camming slot configured to engage the cam pin. Each jaw member includes an electrically conductive tissue sealing surface adapted to connect to a source of electrosurgical energy. A knife blade is supported in the elongated shaft and moveable in a longitudinal direction to cut tissue disposed between the jaw members. A wire retention unit is supported within the housing and includes a plurality of wire clasps and a plurality of guide ribs configured to define at least one wire path.
