A magnetically controlled navigation device for medical capsule endoscopy

Abstract

The invention discloses a capsule endoscope magnetic control navigation device for medical treatment. The capsule endoscope magnetic control navigation device for medical treatment is used for actively controlling movement of capsules in the use process of a capsule endoscope, so that the stomach wall can be completely and effectively detected. The device comprises a hybrid magnetic field generator, a multi-DOF (multi-degree of freedom) motion mechanism and a controller, wherein the multi-DOF motion mechanism is used for carrying the hybrid magnetic field generator to move in a detection area so as to adjust spatial distribution of a magnetic field; the hybrid magnetic field generator comprises a permanent magnet and an electromagnetic coil, can generate a strong magnetic field used for guiding the capsules to move and can adjust the intensity of the magnetic field to a certain degree according to control signals; the controller controls the multi-DOF motion mechanism to move by receiving a control instruction of an operator and feedback signals of a sensor and controls coil current of the hybrid magnetic field generator. The device can guide the capsule endoscope to move in the stomach of a human body in the fixed modes including floating, fixed point floating, posture adjustment and the like, and accordingly, the capsule endoscope can automatically and completely detect the whole stomach wall.

Description

technical field [0001] The present invention relates to the field of medical equipment, in particular to an auxiliary automatic mechanical device for gastric examination using a capsule endoscope, in particular to a medical capsule endoscope magnetic control navigation device, which can be used to control and guide the capsule endoscope in the human body movement and inspection. Background technique [0002] Capsule endoscopy is a human digestive tract inspection tool that is similar in size and shape to capsules and pills, but integrates a complete set of optical photography system, wireless communication system and power supply system. After the capsule is swallowed by the subject, it will move in the gastrointestinal tract, and the inner wall of the gastrointestinal tract will be photographed and inspected along the way, and the image will be sent to the external terminal. Doctors can locate and diagnose the lesion through the received images. [0003] Capsule endoscopy...

AI Technical Summary

Problems solved by technology

The main disadvantage of passive capsule endoscopy is that the capsule endoscope can only move and shoot randomly in the human body, and it is difficult to reach the designated position according to the doctor's instructions, nor can it stay in a specific part, so there are inspection blind spots and possible missed inspections

The internal drive has the following disadvantages: 1. The drive itself needs to consume a lot of energy, which may cause insufficient battery power; 2. The structure of the microcapsule is complicated, production is difficult, and the cost is high; 3. The moving structure may cause damage to the digestive tract; 4. Capsule movement is difficult to control and slow

However, the system is relatively cumbersome, including two sets of magnetic field generating devices and a motion platform; and the so-called dexterous robot does not give a specific implementation method

[0008] Therefore, those skilled in the art are committed to developing a magnetically controlled navigation device for medical capsule endoscopes. While avoiding the structural defects of the internal drive, it solves the problem that the existing externally driven capsule endoscopes generally have relatively large device structures. , complex operation, slow response, etc.
