Method and apparatus for electrosurgical measurement

摘要: An improved method and apparatus for measuring the total energy delivered to a patient during an electrosurgical procedure. target (the patient) is positioned atop dispersive plate constituting first electrode. The included in circuit comprising generator, electrode surgical instrument second A mathematical relationship between current load impedance established selected power settings of said generator. Current measured electrosurgery by suitable means such as transformer. computing device microprocessor determines impedence according particular generator setting being used. then computes from values. integrated over time determine patient. may be further programmed shut off when maximum delivered.
