  • Patent number: 11068852
    Abstract: Methods and systems for controlling the usage of devices with embedded RFID tags including connecting a device to an energy source and reading data from a memory device incorporated in the device. The data may include a unique identifier (UID), a usage value, an activation value, a reprocessing value, and/or a sterilization indicator. The usage value is incremented when the device is connected to the energy source and the activation value is incremented when the device is activated permitting energy to flow from the energy source to the device. Usage of the device is prevented if the UID is on a list of prohibited UIDs, the usage value is not lower than a usage limitation value, the reprocessing value equals a reprocessing limitation value, the activation value equals an activation limitation value, and/or the sterilization indicator does not indicate that the device has been sterilized since its previous usage.

  • Patent number: 9931131
    Abstract: A method of performing surgery includes the steps of providing a forceps having a housing including a shaft that extends therefrom and at least one handle moveable relative to the housing and providing an end effector assembly configured to selectively engage a distal end of the shaft. The method also includes the steps of inserting the forceps through a first opening formed in a body; inserting the end effector assembly through a second opening formed in the body; engaging the end effector assembly with the distal end of the shaft in vivo; and actuating the end effector assembly by moving the handle relative to the housing. The method may also include the steps of providing a coupling at the distal end of the shaft, and engaging, via the coupling, the distal end of the shaft with the end effector assembly.

  • Patent number: 9549775
    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.

  • Patent number: 9023043
    Abstract: An electrosurgical forceps includes a shaft having a pair of jaw members at a distal end movable about a pivot from a first position disposed in spaced relation relative to one another to a second position wherein the jaw members are closer to one another for grasping tissue. A movable handle actuates a drive assembly to move the jaw members relative to one another. One (or both) of the jaw members is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of conducting electrical energy to tissue held therebetween. A flexible insulating boot is disposed on an exterior surface of one or both jaw members and about the pivot and at least one retention element is configured to operably couple to both a proximal end of the jaw members and a distal end of the flexible insulating boot.

  • Patent number: 8968305
    Abstract: A forceps includes an end effector assembly defining a longitudinal axis and including a pair of jaw members disposed in opposing relation relative to one another. At least one jaw member is moveable relative to the other between a spaced-apart position and an approximated position for grasping tissue therebetween. Each jaw member includes a jaw housing and an opposed electrically conductive sealing surface. The opposed sealing surfaces define a sealing area therebetween. A cutting mechanism is disposed on the jaw housing of one of the jaw members opposite the respective sealing surface and is configured to cut tissue externally-positioned relative to the sealing area upon translation of the cutting mechanism with respect to tissue.

  • Patent number: 8394095
    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.

  • Patent number: 7935052
    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.
