    摘要: An end effector assembly for use with an electrosurgical instrument is provided. The end effector assembly has a first jaw member having a first pair of tissue contacting surfaces and an insulator disposed therebetween. The end effector assembly also has a second jaw member that includes a second pair of tissue contacting surfaces, a pair of insulators disposed between the second pair of tissue contacting surfaces, and a cutting element disposed between the pair of insulators. The relative movement of the first jaw member toward the second jaw member causes the insulator of the first jaw member and the pair of insulators of the second jaw member to pinch tissue disposed between the first jaw member and the second jaw member.

    摘要: An electrosurgical instrument having opposing end effectors and a handle for effecting movement of the end effectors relative to one another, includes a pair of electrodes each including an electrically conductive surface (e.g., which can be dimensioned for sealing, clamping and/or cutting), an insulating substrate having a first edge, and an insulating layer positioned in a channel formed by the electrically conductive surface within the first edge between the conductive surface and the first edge of the insulating substrate. The insulating layer has a portion proximal to the electrically conductive surface and a portion distal from the electrically conductive surface and a gradient such that the proximal portion has a lower dielectric strength than the distal portion. A coating on one of the pair of electrodes may be disposed in at least partial non-vertical registration with a coating on the opposing one of the pair of electrodes.

    摘要: An electrode sealing assembly is designed for use with an electrosurgical instrument for sealing tissue and includes first and second jaw members each having an insulative housing and being movable from a first position in spaced relation relative to one another to at least one second position for grasping tissue therebetween. Each of the jaw members includes an electrically conductive sealing member disposed within the respective insulative housing. At least one of the insulative housings includes at least one tissue engaging surface configured to extend beyond the electrically conductive sealing member of one of the jaw members. The tissue engaging surface of the insulative housing cooperates with the opposing insulative housing of the opposing jaw member to both pinch and spread tissue when the jaw members are moved to the second position to decrease extraneous energy transmittance to tissue surrounding the jaw members.

    摘要: An end effector assembly for use with a bipolar forceps includes a pair of opposing first and second jaw members at least one of which being movable relative to the other to grasp tissue therebetween. Each jaw member includes a pair of spaced apart, electrically conductive tissue sealing surfaces. Each tissue sealing surface is adapted to connect to a source of electrosurgical energy to conduct electrosurgical energy through tissue held therebetween to effect a tissue seal. The forceps also includes an insulator disposed between each pair of electrically conductive sealing surfaces and an electrically conductive cutting element disposed within each insulator and defining a geometrical configuration including a plurality of peaks having a period that is a multiple of an operating frequency of the electrosurgical energy. The cutting elements are adapted to connect to the source of electrosurgical energy to conduct electrosurgical energy through tissue held therebetween to effect a tissue cut.

    摘要: A system and method for optimizing tissue separation using modulated or duty cycle controlled waveforms on desiccated tissue, where the desiccated tissue has a high electrical impedance. In bipolar electrosurgical procedures, tissue separation is separated with the application of an electrical signal. When tissue does not completely separate and becomes desiccated, generator may generate a duty cycle controlled waveform with specified duty cycle and frequency or modulated waveform. Modulated waveform is generated by adding or multiplying one or more waveforms together. Modulated or duty cycle waveforms create power pulses with higher voltages and a low RMS value. Power pulses drive power and create heat in the high impedance tissue. The creation of heat helps to mobilize water content adjacent to the desiccated tissue. The heating and mobilization of water induces motion into the tissue and aids in the complete separation of tissue while keeping the RMS power low.

    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.
