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： A laparoscopic bipolar electrosurgical instrument for sealing tissue includes a handle having an elongated tube affixed thereto. The tube includes first and second jaw members having electrically conductive sealing surfaces attached to a distal end thereof which are movable from a first position for approximating tissue to a second position for grasping tissue therebetween. The handle includes a fixed handle and a handle which is movable relative to the fixed handle to effect movement of the jaw members from the first position to the second position for grasping tissue. The jaw members connect to a source of electrosurgical energy such that the opposable sealing surfaces are capable of conducting electrosurgical energy through tissue held therebetween. A stop is included for maintaining a minimum separation distance between opposing sealing surfaces. A ratchet is also included to maintain a closure force in the range of about 7 kg/cm2 to about 13 kg/cm2 between opposing sealing surfaces.

摘要： An end effector assembly for use with an instrument for sealing vessels and cutting vessels includes a pair of opposing first and second jaw members which are movable relative to one another from a first spaced apart position to a second position for grasping tissue therebetween. Each jaw member includes a pair of spaced apart electrically conductive tissue contacting surfaces which each have an insulator disposed therebetween, the conductive surfaces are connected to an electrosurgical energy source. The first jaw member includes an electrically conductive cutting element disposed within the insulator which extends towards the second tissue contacting surface to create a gap therebetween. The cutting element is inactive during the sealing process while the two pairs of electrically conductive surfaces are activated to seal tissue. During the cutting process, the cutting element is energized to a first potential and at least one electrically conductive tissue contacting surface is energized to a different potential to effect a tissue cut through the tissue held between the jaw members along the already formed tissue seal.

摘要： An endoscopic bipolar forceps for sealing and dividing tissue which includes an elongated shaft having opposing jaw members at a distal end thereof. The jaw members are movable relative to one another about a pivot from a first spaced position to a second closed position to grasp tissue. Each jaw member is adapted to couple to a generator for conducting energy to effect a seal. The forceps also includes a handle assembly and a longitudinally reciprocating knife assembly which is translatable to sever tissue. The knife assembly includes a bifurcated knife bar having two forks which ride about the pivot during translation of the knife. One or more non-conductive stop members are operatively associated with the jaw members to regulate the distance between the jaw members when closed.

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： 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.
