  • Patent number: 11877790
    Abstract: An electrosurgical instrument includes a housing and an elongated shaft extending from the housing. An end effector is disposed at a distal portion of the elongated shaft. The end effector is configured to deliver electrosurgical energy to tissue. The end effector includes a first jaw member having a first electrode plate and a second jaw member having a second electrode plate. A movable handle is operably coupled to the housing. The movable handle is configured to move at least one of the first or second jaw members between an open position and a closed position. A first plate is disposed on the first jaw member. A second plate is disposed on the first plate. The second plate includes an opening defined therein. A bead is disposed on the first plate and is configured to protrude through the opening defined in the second plate.

  • Patent number: 9848935
    Abstract: A surgical instrument includes a shell having a housing and a shaft. The shell including first and second shell components configured to engage one another to form the shell, each of which is monolithically formed to include a housing portion and a shaft portion. Upon engagement of the first and second shell components with one another, the housing portions cooperate to form the housing of the shell while the shaft portions cooperate to form the shaft of the shell. An end effector assembly is operably coupled to the shaft at a distal end of the shaft. A handle assembly is operably coupled to the housing. A drive assembly disposed within the shell is operably coupled between the handle assembly and the end effector assembly such that actuation of the handle assembly manipulates the end effector assembly.
