    摘要: The invention provides an electrosurgical tissue penetrating probe (e.g., a trocar) (24) for use with surgical procedures such as a laparoscopy. The trocar (24) has a stylet (36) disposed within the housing member (34), having an active electrode (42) disposed on a distal end thereof to deliver electrosurgical energy to the target tissue in contact with the stylet (36). A return electrode (48) is disposed on the housing member to form part of a return electrical path to the delivery electrosurgical energy. The invention also provides an electrosurgical trocar system having an impedance monitor and associated power regulating circuitry to control the amount of electrosurgical energy delivered to tissue so that the measured tissue impedance is maintained within a preselected range.

    摘要: A surgical trocar (10) includes an operative sleeve (32) adapted for disposition across a tissue barrier and an obturator (36) removably disposed in the sleeve (32). A source of energy is introduced to a cutting element (42) disposed at the distal end (43) of the obturator (36) for energizing the cutting element (42) to cut the tissue barrier (18). The distal end (43) of the obturator (36) and the distal end of the operative sleeve (32) can be advanced through the cut tissue and the obturator (36) removed leaving the sleeve (32) operatively disposed for further surgery.

    摘要: A device for dissipating electrical energy from a surgical device is provided. The electrical energy is induced on the surgical device when a charge-inducing instrument, e.g. an unipolar electrocautery device, is energized in proximity thereto. The induced energy is dissipated by conveying the energy along an electrically conductive element 34 to an energy dissipation region. In a preferred embodiment of the invention, the surgical device is a cannula 26 fabricated from a dielectric material, e.g., fiberglass, and induced electrical energy is dissipated by contacting the energy dissipation 36 region, e.g., a conductive band 36 around the periphery of the cannula, with the body wall of the patient. An alternative means for grounding is achieved by providing an electrical fitting on a cannula housing which remains external to the patient's body, and securing a grounding wire thereto.

    摘要: A device (1; 1') for treating the ligamentum flavum by radio frequency comprises:
    a hand grip (2; 2') to be held by an operator;
    a cannula (10; 10') fixed at its proximal end (31) to the hand grip (2; 2') and extending longitudinally from said hand grip (2; 2') to an opposed distal end of the cannula (10; 10'), designed to reach the ligamentum flavum;
    at least one electrode (11; 11') which is electrically connectable to a radio frequency generator and is slidably housed in the cannula (10; 10');
    the cannula (10; 10') being provided with a hole (13) to allow the electrode (11; 11') to emerge from the cannula (10; 10');
    an actuating device (26; 26') of the electrode (11; 11') provided in the hand grip (2; 2') for moving the electrode (11; 11'), wherein

    摘要: An CUSA having a cannula with an ultrasonic frequency vibrating tip with a flue disposed around the cannula. A first electrode is disposed on an outside of the flue and an RF generator provides current to the first electrode. A current flow is formed between the electrode and the tip and the tip acts as a ground. The first electrode can take the shape of a complete circumferential ring or a partially circumferential ring. The first electrode can be removably disposed on and/or movable along a length of the flue to allow the surgeon to "clip-on" or adjust the electrode at the position of their choice. A second electrode can be disposed on the outside of the flue and proximal to the first. A second current flow can be formed between the first electrode and the second electrode.
