    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 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.

The system also includes one or more sensors which determine a gap distance between the sealing plates of the jaw members and a microprocessor which is adapted to communicate with the sensor and measure an initial gap distance between the sealing plates as well as to generate a desired gap distance trajectory based on the initial gap distance. The microprocessor is further adapted to communicate with the at least one sensor in real time to adjust output level of the electrosurgical generator as a function of the measured gap distance during the sealing process.
