System and Method for Controlling RF Output During Tissue Sealing
First Claim
1. An electrosurgical system for sealing tissue, comprising:
- a forceps including opposing jaw members that cooperate to grasp tissue therebetween, each jaw member including a sealing plate that is connected to an electrosurgical generator and is configured to communicate electrosurgical energy through the tissue held therebetween;
at least one sensor configured to determine a gap distance between the sealing plates of the jaw members; and
a microprocessor programmed to communicate with the at least one sensor to measure an initial gap distance between the sealing plates and to generate at least one desired gap distance value based on the initial gap distance, the microprocessor further programmed to communicate with the at least one sensor to adjust an output level of the electrosurgical generator as a function of the measured gap distance during the sealing process.

Abstract
An electrosurgical system for sealing tissue is disclosed. The system includes a forceps having opposing jaw members that cooperate to grasp tissue therebetween, wherein each of the jaw members includes a sealing plate that is connected to an electrosurgical generator and is configured to communicate electro surgical energy through the tissue held therebetween. The system also includes at least one sensor which determines a gap distance between the sealing plates of the jaw members and a microprocessor programmed to communicate with the at least one sensor to measure an initial gap distance between the sealing plates and to generate at least one desired gap distance value based on the initial gap distance, the microprocessor further programmed to communicate with the at least one sensor to adjust output level of the electrosurgical generator as a function of the measured gap distance during the sealing process.
