  • Publication number: 20070213706
    Abstract: An endoscopic forceps for treating tissue includes a housing having a shaft affixed thereto which has first and second jaw members attached to a distal end thereof. The forceps also includes an actuator for moving jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. Each of the jaw members is adapted to connect to a source of electrosurgical energy such that the jaw members are selectively capable of operating in a bipolar mode which enables the jaw members to conduct bipolar energy through tissue held therebetween to treat tissue. The forceps also includes a monopolar element housed within the first jaw member and integrally associated with the knife. The monopolar element is selectively movable from a first position within the first jaw member to a second position distal to the first jaw member.

  • Publication number: 20070142834
    Abstract: An endoscopic forceps for treating tissue includes a handle assembly having a elongated shaft extending therefrom that is movable relative to the handle assembly by an actuator. The forceps also includes an end effector assembly with first and second jaw members that are movable about a pivot for clamping tissue. Each of the jaw members include: an insulative housing having an electrically conductive, inwardly facing tissue contacting surface and a flange with a camming surface. The flange includes a spring-like tail that mounts at least partially within the distal end of the elongated shaft to bias the jaw members in an open configuration. A proximal portion of the spring-like tail is biased radially outward within the distal end of the elongated shaft. The actuator is movable to actuate the elongated shaft to cam the flanges to pivot the jaw members to clamp tissue.

  • Publication number: 20070106297
    Abstract: An endoscopic forceps includes a housing having a shaft attached thereto, the shaft including a pair of jaw members disposed at a distal end thereof. The forceps also includes a drive assembly disposed in the housing which moves the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for manipulating tissue. A pair of handles is operatively connected to the drive assembly and the handles are movable relative to the housing to actuate the drive assembly to move the jaw members. Each of the jaw members is adapted to connect to a source of electrical energy such that the jaw members are capable of conducting energy for treating tissue. The forceps also includes a first switch disposed on the housing which is activatable to selectively deliver energy of a first electrical potential to at least one jaw member for treating tissue in a monopolar fashion.

  • Publication number: 20070106295
    Abstract: Either an endoscopic or open bipolar forceps includes a flexible, generally tubular insulating boot for insulating patient tissue, while not impeding motion of the jaw members. The jaw members are movable from an open to a closed position and the jaw members are connected to a source of electrosurgical energy such that the jaw members are capable of conducting energy through tissue held therebetween to effect a tissue seal. A knife assembly may be included that allows a user to selectively divide tissue upon actuation thereof. The insulating boot may be made from a viscoelastic, elastomeric or flexible material suitable for use with a sterilization process including ethylene oxide. An interior portion of the insulating boot may have at least one mechanically interfacing surface that interfaces with a mechanically interfacing surface formed between the shaft and a jaw member or with a mechanically interfacing surface disposed or formed on the shaft or a jaw member.

The forceps also including an end effector assembly attached to a distal end of the shaft which has first and second jaw members which are movable about a pivot from a first position in spaced relation relative to one another to a second position for clamping tissue. Each of the jaw members include: an insulative outer housing having an electrically conductive, inwardly facing tissue contacting surface and a proximal flange with a camming surface. The proximal flange being provided with a spring-like tail which mounts within the distal end of the elongated shaft to bias the jaw members in an open configuration. The actuator is movable relative to the handle to actuate the elongated shaft to cam the proximal flanges to pivot the jaw members toward the second position to clamp tissue.
