  • Patent number: 9579145
    Abstract: An endoscopic forceps is disclosed including an end effector assembly having two jaw members movable from a first position in spaced relation relative to one another to at least a second position closer to one another for grasping tissue therebetween. Each of the jaw members is connectable to an electrosurgical energy source for conducting energy through tissue held therebetween. The jaw members are biased to the first position. The end effector assembly of the endoscopic forceps further includes a wire snare having a proximal end connectable to an electrosurgical energy source and a distal end translatably extending out of one of the jaw members and operatively associated with the other of the jaw members. In use, withdrawal of the proximal end of the wire snare results in movement of the jaw members from the first position to a second position and clamping of the tissue between the jaws.

  • Patent number: 8361069
    Abstract: A bipolar electrosurgical instrument has a first and a second set of needle like structures. Each set of needle like structures is functional for puncturing the skin of a patient on opposing sides of a wound or cut. Each needle comprises a body and a pointed portion at a distal end. The distal end is structured to form a sealing surface with an opposing needle on a needle of the other set. The sealing surfaces are adapted to connect to an electrical energy source such that the sealing surfaces are capable of conducting bipolar energy therebetween. The first and second set of needle like structures are movable from a first position where the needles are disposed in spaced relation relative to one another to a second position where the first and second sets of needles members are closer to one another. A mechanical force applied to or within a housing is utilized to move the needles sets from the first position to the second position.

  • Publication number: 20030109875
    Abstract: A removable electrode assembly for use in combination with a forceps having opposing end effectors and a handle for effecting movement of the end effectors relative to one another. The electrode assembly includes a housing which is removably engageable with the forceps and a pair of electrodes which are attachable to a distal end of the housing. The electrodes are removably engageable with the end effectors of the forceps such that the electrodes reside in opposing relation relative to one another. The electrode assembly also includes a cover plate which is removably attachable to the housing and at least one stop member for controlling the distance the electrodes move relative to one another.
