Seal and separate algorithm

摘要

A method for controlling delivery of energy to seal and divide tissue includes applying energy to tissue in a first phase through an electrosurgical forceps having at least one electrically energizable electrode. The method also includes detecting a predetermined condition based on the application of energy to tissue during the first phase. The method also includes applying energy to tissue during a second phase upon detection of the predetermined condition and providing tension to the tissue during the second phase to separate the tissue.

1. A method for controlling delivery of energy to seal and divide tissue, the method comprising:
applying energy to tissue in a first phase through an electrosurgical forceps having a first electrically energizable electrode and a second electrically energizable electrode; detecting a predetermined condition based on the application of energy to tissue during the first phase; applying energy to tissue during a second phase through the first and second electrically energizable electrodes upon detection of the predetermined condition; manipulating the first and second electrically energizable electrodes relative to the tissue to provide tension on the tissue during the second phase to separate the tissue; detecting a predetermined change in the energy applied to the tissue during the second phase, the predetermined change being indicative of tissue separation; and terminating the second phase upon detection of the predetermined change.
