Abstract

An electromagnetic micro-actuator for a gastrointestinal robot in the field of endoscopic instruments comprises a stator mechanism and a rotor mechanism. The rotor mechanism is arranged inside the stator mechanism and comprises a rectiblock, two coils, an asymmetrical rotor and an output shaft, the rotor is arranged on the output shaft, the first coil and the second coil are wound on the asymmetrical rotor and are both positioned at the outer edge of the rotor, and the rectiblock and the asymmetrical rotor are connected and concentrically arranged. By the electromagnetic micro-actuator for the gastrointestinal robot, axial size of the gastrointestinal robot is shortened, space utilization rate of the gastrointestinal robot is improved, and miniaturization of the gastrointestinal robot is achieved.

Description

technical field

[0001] The invention relates to a device in the technical field of endoscope instruments, in particular to a miniature electromagnetic driver for a gastrointestinal tract robot. Background technique

[0002] With the continuous acceleration of people's life rhythm and the continuous change of diet structure, there are more and more digestive tract diseases. Gastric cancer is one of the most common malignant tumors in the world. About 640,000 people die from gastric cancer every year, ranking second in the cause of cancer death. The incidence of bowel cancer in the world is also increasing at a rate of 2% per year, and nearly 500,000 people die of bowel cancer every year, while the growth rate of the incidence of bowel cancer in my country is twice the world level, and the mortality rate ranks third among cancer deaths. . Gastrointestinal system diseases are chronic diseases with high morbidity, mortality and disability. Therefore, early detection, prevention...
