A multi-output minimally invasive surgical system based on resistive network

Abstract

The present invention relates to a multi-output minimally invasive surgery system based on a resistance network. The multi-output minimally invasive surgery system includes a minimally invasive knife and a control mechanism; the minimally invasive knife is an ultrasonic knife or a radio frequency knife, and the radio frequency knife is a double Pole output radio frequency cutter or unipolar output radio frequency cutter, the minimally invasive cutters all have control buttons; the minimally invasive cutters are electrically connected to the control mechanism through the cutter interface; the control mechanism includes an ADRC frequency controller and state judgment controller. By combining the ADRC frequency controller and the resistance network control, the real-time monitoring and debugging of the working frequency of the tool and the connection relationship between the tool can be realized.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-output minimally invasive surgery system based on a resistance network. Background technique [0002] High-tech applications in the field of medical devices are intensive and feature cross-integrated applications of technologies. Scalpel, as an indispensable tool for surgery, plays an extremely important role in the whole operation process. Ultrasonic scalpel system and radio frequency scalpel system are the two least invasive surgical equipment systems in the world. Because of their good medical effects such as less intraoperative bleeding and quick postoperative recovery, they have also received great response in the medical field. [0003] The ultrasonic knife system includes a host, a handle, an ultrasonic transducer, an ultrasonic energy amplifier, an ultrasonic energy conduction part, and a knife. The handle controls the ultrasonic transducer to convert th...

Problems solved by technology

[0007] In order to solve the problem that in the actual operation of the existing multi-output minimally invasive scalpel system, minimally invasive knives with different outputs need to be replaced multiple times during the same operation, because the connection between the internal circuit of the mixed output control host and the knife is usually Single docking relationship, it is difficult to carry out the technical problem of real-time frequency control and monitoring of the knife connection relationship in time. The present invention provides a multi-output minimally invasive surgical system based on a resistor network, and then realizes real-time monitoring of the working frequency of the knife and the knife connection relationship and debug
