Medical spherical micro robot remote control system and working method thereof

Abstract

The invention discloses a medical spherical micro robot remote control system. The medical spherical micro robot remote control system is characterized by comprising an upper computer control signal transmission unit, a radio frequency receiving unit, a control signal generation unit, a state display unit and a tri-axial outer magnetic field generation unit. A working method of the medical spherical micro robot remote control system comprises the following steps: driving a robot to move under the action of a tri-axial outer magnetic field; deducing a corresponding relationship between frequency and the magnetic field; changing a tri-axial current signal frequency parameter; displaying a state; controlling a motion way. The medical spherical micro robot remote control system has the advantages that remote control and wireless motion control of a spherical micro robot are realized; high flexibility is realized; the potential threat of irradiation is lowered; the medical spherical micro robot remote control system is low, and is convenient to carry; the motion form of the medical spherical micro robot is controlled through a key instruction.

Description

[0001] (1) Technical field: [0002] The invention belongs to the field of medical micro-robots, and in particular relates to a remote control system of a medical spherical micro-robot and a working method thereof, which are mainly applicable to remote diagnosis and treatment of human gastrointestinal diseases and subsequent related medical operations. [0003] (two) background technology: [0004] China is a big country for gastric cancer, and about 35% of gastric cancer cases in the world occur in China. Gastrointestinal diseases, such as bleeding, tumors and ulcers, are common and frequently-occurring diseases that affect people's life and health, and their morbidity and mortality are relatively high. Patients suffer a lot during traditional endoscopic examination, about 0.075% of patients will be complicated with gastrointestinal perforation, and very few patients even suffer from cardiac arrest, so it cannot be widely accepted by patients. [0005] Medical micro-robot is ...

AI Technical Summary

Problems solved by technology

[0006] However, clinically applied medical microrobots rely on the physiological peristaltic force of the gastrointestinal tract to move passively, and cannot achieve acceleration, stop, and retreat, which limits their comprehensive diagnosis and treatment of gastrointestinal diseases.

At the same time, the control of medical micro-robots is directly controlled by local doctors, which has high requirements for operating doctors and is difficult to meet the needs of personalized treatment and telemedicine

In addition, the medical micro-robot body lacks relevant devices for medical operations, and its functions are single.

Finally, when the medical microrobot is in the gastrointestinal environment, the outside world cannot accurately determine the position of the medical microrobot and other information, and there are potential safety hazards in clinical applications.

These problems seriously limit the clinical application of medical microrobots.
