Electrosurgical monopolar apparatus with arc energy vascular coagulation control

摘要

A system for delivering electrosurgical energy is provided. The system includes an electrosurgical instrument comprising at least one electrode and an electrosurgical generator coupled to the electrosurgical instrument. The electrosurgical generator includes an output stage configured to generate electrosurgical energy; and a controller coupled to the output stage, the controller configured to control the output stage to output electrosurgical energy at a predetermined power level to generate an arc between the at least one electrode and tissue and to output electrosurgical energy at a predetermined current level once the arc is generated to sustain the arc.

1. A system for delivering electrosurgical energy, comprising:
an electrosurgical instrument comprising at least one electrode; and an electrosurgical generator coupled to the electrosurgical instrument, the electrosurgical generator comprising: an output stage configured to generate electrosurgical energy; and a controller coupled to the output stage, the controller configured to control the output stage to output electrosurgical energy at a predetermined power control mode having a first current level to generate an arc between the at least one electrode and tissue and to output electrosurgical energy at a predetermined current level control mode having a second current level different from the first current level once the arc is generated to sustain the arc.
