CONTROLLER FOR ELECTROSURGICAL MEDICAL DEVICES

摘要

A control unit controls delivery of RF energy generated by an RF generator to a medical device configured to perform a medical procedure. The control unit may be separate from the RF generator, and may have an input that may be attached to an output of the RF generator. The control unit includes switching circuitry that is closed while an amount of RF energy is transmitted through the control unit to the medical device. The switching circuitry opens when the amount of RF energy reaches a threshold level.

1. A control unit that is configured to control delivery of radio frequency (RF) energy to a medical device, the control unit comprising:
switching circuitry configured to switch between a closed state and an open state,
wherein when the switching circuitry is configured in the closed state, the switching circuitry is configured to permit RF energy received from an RF generator to be output by the control unit to a medical device; andwherein when the switching circuitry is configured in the open state, the switching circuitry is configured to prevent RF energy from being output by the control unit to the medical device; energy measurement circuitry configured to:
measure an amount of RF energy delivered to the medical device; andswitch the switching circuitry from the closed state to the open state when the amount of RF energy delivered to the medical device reaches a predetermined RF energy level.
