Title:
DUAL-LOOP, AUTOMATIC HEALTH MANAGING, MULTI-OUTPUT MINIMALLY INVASIVE SURGERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/000541
Kind Code:
A1
Abstract:
A dual-loop, automatic health managing, multi-output minimally invasive surgery system, comprising a control system (1) and a cutter system (2), the control system (1) comprising a control module (11) and an isolated module (12) connected by means of an optocoupler. The control module (11) comprises a controller (6), control circuits (61, 62), an amplification drive circuit (63) and a power MOSFET (64). The isolated module (12) comprises an isolated step-up transformer (126), a measurement module MCU (122), measurement circuits (7, 8) and a cutter output circuit (124). The measurement circuit comprises an inner loop measurement circuit (7) and an outer loop measurement circuit (8). An output terminal of an isolated transformer connects to the cutter output circuit (124), and an input terminal and an output terminal of the isolated step-up transformer (126) connect to the controller (6) by means of the inner loop measurement circuit (7) and the outer loop measurement circuit (8) respectively. The cutter system (2) comprises a minimally invasive cutter and an ADRC frequency controller (621). 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. By means of establishing a dual-loop measurement management mechanism having an inner loop and an outer loop to perform dual-loop sampling on minimally invasive cutter working data, the real-time performance and accuracy of sampling the data is improved, ensuring stability and and safe operating performance in the working process of a multi-output minimally invasive surgery system.
