    Abstract: An end-effector assembly includes opposing jaw members movably mounted with respect to one another. At least one of the jaw members includes a temperature-sensing electrically-conductive tissue-contacting plate having a tissue-contacting surface and a bottom surface. A first layer is disposed on one or more portions of the bottom surface of the temperature-sensing electrically-conductive tissue-contacting plate. The first layer includes an electrically-insulative material. One or more openings are formed in the first layer. One or more electrically-conductive traces are formed over the electrically-insulative material and associated with the one or more openings. One or more temperature sensors are coupled to the bottom surface of the temperature-sensing electrically-conductive tissue-contacting plate and associated with the one or more openings. The one or more openings are each configured to receive at least a portion of the one or more temperature sensors therein. The one or more temperature sensors are electrically coupled to the one or more electrically-conductive traces.

    Abstract: A system for the manufacture of an end effector assembly which is configured for use with an electrosurgical instrument configured for performing an electrosurgical procedure is provided. The system includes a photolithography module that is configured to etch one or more pockets on a seal surface of the seal plate. A vacuum module is configured to raise, transfer and lower a spacer from a location remote from the pocket(s) on the seal plate to the pocket on the seal plate(s). An adhesive dispensing module is configured to dispense an adhesive into the pocket on the seal plate. An optical module is configured to monitor a volume of the adhesive dispensed within the pocket and monitor placement of the spacer within the pocket.

    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.
