  • Patent number: 10603102
    Abstract: A system includes an energy source and a surgical device. The energy source has a receptacle configured to delivery energy to the surgical device through a receptacle. The surgical device is configured to deliver the energy to tissue. The surgical device includes a plug selectively engagable to the receptacle to couple the surgical device to the energy source. The plug includes a prong configured to mechanically transition from a condition permitting engagement of the plug and the receptacle to another condition inhibiting engagement of the plug with the receptacle upon reaching a predetermined usage threshold.
    Type: Grant

  • Patent number: 9713493
    Abstract: The present disclosure is directed to an electrosurgical instrument having a housing that includes a generator configured to output electrosurgical energy and a controller configured to control the output of the generator. The instrument also includes a switch coupled to the controller and configured to provide a signal to the controller to select the energy modality of the electrosurgical energy. An indicator is also included to provide an indication of the selected energy modality.

  • Patent number: 9326812
    Abstract: A surgical instrument is provided and includes a housing including an elongated shaft. The housing includes a docking portion that includes one or more apertures defined therein and electrical circuitry disposed therein. An end effector is operably supported at a distal end of the elongated shaft. A battery assembly is selectively and pivotably engageable with the docking portion of the housing and configured to generate electrical energy. The battery assembly includes one or more protrusions that are configured to releasably engage the aperture(s) on the docking portion and a latch mechanism that is movable from an initial position for latching the battery assembly to the docking portion to a subsequent position for unlatching the battery assembly from the docking portion. The battery assembly is adapted to communicate with the electrical circuitry of the docking member upon insertion of the battery assembly into the at least one aperture.

  • Publication number: 20150066026
    Abstract: A surgical instrument includes an end effector assembly having jaw members movable to grasp tissue therebetween. One or both jaw members is adapted to connect to a source of energy for treating tissue grasped and one or both of the jaw members is adapted to connect to a source of energy for electrically cutting tissue. A first switch assembly is selectively activatable for supplying energy to treat tissue. A second switch is selectively activatable for supplying energy to electrically cut tissue. The tactile feel and range of motion during actuation of the second switch assembly mimics the tactile feel and range of motion of activation of a mechanical actuator that advances a cutting blade between the jaw members to mechanically cut tissue.
