Title:
ULTRASOUND/RADIO FREQUENCY MINIMALLY INVASIVE SURGERY SYSTEM HAVING ISOLATED COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2021/000538
Kind Code:
A1
Abstract:
An ultrasound/radio frequency minimally invasive surgery system having isolated communications, comprising a control system (6) and a cutter system (5), the control system (6) comprising a control module (62) and an isolated module (61) connected by means of an optocoupler. The control module (62) is an electrically non-isolated region, and the isolated module (61) is an electrically isolated region. The cutter system (5) comprises an minimally invasive cutter having an ID chip, an ID recognition mechanism, and an ADRC frequency controller. The minimally invasive cutter is an ultrasonic cutter or a radio frequency cutter, the radio frequency cutter being a bipolar output radio frequency cutter or a monopolar output radio frequency cutter. Electric current information and energy information from a patient contact region is prevented from directly flowing to a non-isolated electrical region of the external environment, preventing accidentally produced electric current information and other unordered currents from causing ground faults, thus breaking the current grounding loop and ensuring safe and stable operation of the circuit. Meanwhile, by means of controlling the frequency of the cutter in real time, the stability of the minimally invasive surgery system is improved.
