    摘要： Bipolar electrosurgical instrument having a first and a second opposing jaw member at a distal end thereof, wherein each jaw member includes an outer housing, and an inner tissue engaging surface corresponding to the inner tissue engaging surface of the opposing jaw. The instruments includes the ability to move 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 cooperate to grasp tissue. The jaws include asymmetrical electrodes disposed on the inner tissue engaging surfaces. A first contact region of the electrode has a greater surface area than that of the second contact region. During resection procedures wider electrodes impart improved sealing energy to the patient-side vessel while providing sufficient energy to resected tissue to effect hemostasis.

    摘要： A bipolar electrosurgical instrument has opposable seal surfaces on its jaws for grasping and sealing vessels and vascular tissue. Inner and outer instrument members allow arcuate motion of the seal surfaces. An open lockbox provides a pivot with lateral support to maintain alignment of the lateral surfaces. Ratchets on the instrument members hold a constant closure force on the tissue during the seal process. A shank portion on each member is tuned to provide an appropriate spring force to hold the seal surfaces together. During surgery, the instrument can be used to grasp and clamp vascular tissue and apply bipolar electrosurgical current through the clamped tissue. In one embodiment, the seal surfaces are partially insulated to prevent a short circuit when the instrument jaws are closed together. In another embodiment, the seal surfaces are removably mounted on the jaws.

    摘要： Various safe switching mechanisms are provided for use with electrosurgical instruments which prevent arcing between the high-energy contacts as the high-energy source is activated. The switching mechanisms generally include a pair of high-energy contacts and a pair of activation contacts. An actuator is provided which initially engages the high-energy contacts in advance of engagement of the activation contacts to prevent arcing and subsequently disengages the activation contacts in advance of the high-energy contacts as the energy source is deactivated. A method of switching power to an electrosurgical instrument while avoiding damage to high-energy contacts is also disclosed.

    摘要： An electrode assembly for use with an instrument for sealing and cutting vessels and/or tissue is provided. The assembly includes a pair of opposing first and second jaw members. Each jaw member includes at least one electrically conductive tissue sealing surfaces extending along a length thereof. Each tissue sealing surface is adapted to connect to a source of electrosurgical energy to effect a tissue seal. An insulator is disposed adjacent to the at least one the electrically conductive sealing surfaces. The jaw members include an electrically conductive cutting element which effectively cuts tissue within pre-defined cutting zone between the jaw members. The polarity of the cutting element and electrically conductive sealing surfaces may be manipulated depending upon whether tissue sealing or tissue cutting is desired.
