Problems solved by technology

The linear electromagnetic driving method is a new type of driving method that has appeared in recent years. It has the advantages of simple mechanism, controllability, large driving displacement, and easy manufacture. However, the existing linear electromagnetic drivers are generally large in size and cannot meet the needs of endoscopes. The requirement of a narrow working space cannot be achieved simply by reducing the existing specifications
This is because in order to make full use of the excitation of the coil winding and the permanent magnet, the tubular permanent magnet with full radial magnetization is often used, and the magnetization can hardly b

Example Embodiment

[0027] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0028] The overall structure of the robot system of the present invention is as follows: figure 1As shown, it mainly includes: front cabin 1, connecting pin 2, cross universal joint 3, sealing film 4, several linear drives 5, rear cabin 6, controller 7, monitor 8. The front cabin 1 is rigidly connected with the first linear driver 5 through the connecting pin 2 , and the rear end of the last linear driver 5 is connected with the rear cabin 6 through the connecting pin 2 . The linear drives 5 are connected to one another via universal joints 3 . The outside of the whole robot is sealed with an elastic sealing film 4 . The cable is connected to the controller 7 and the monitor 8 by the tail of the back cabin, and is used for controlling the robot and displaying images respectively.

[0029] The structure of front cabin 1 among the present invention is ...

Abstract

The active intestinal endoscope robot system consists of front compartment, linear drivers and back compartment connected together, is sealed completely with elastic sealing film, and is connected via cable led out from the back compartment to the controller and the monitor for controlling the robot and displaying image. The front compartment is provided with mini color image sensor, lens, processing chip and memory alloy to control imaging direction and walking direction. The linear drivers are connected via cross couplers for multiple freedom motion, and have adhered permanent magnets to obtain near radial magnetic field and realize the motion via the mutual action between the current carrying winding and the permanent magnetic field. The back compartment is for winding and unwinding cable to ensure the motion. The present invention is used in the intestinal detection.

Description

technical field [0001] The invention relates to an intestinal endoscope robot system, in particular to an active intestinal endoscope robot system based on the principle of peristalsis, which belongs to the fields of electromechanical technology and medicine. Background technique [0002] The active endoscope, which embodies the technical requirements of "less invasive and no planing" in vivo diagnosis and treatment, has become the focus of research and development in the international biomedical device industry. Compared with traditional endoscopes, in addition to the advantages of traditional endoscopes, active endoscopes also have: (1) easy to use; (2) no pain or less pain for patients; (3) fast and efficient, etc. . According to reports, Japan's Tohoku University has developed a serpentine drive device suitable for human intestines or blood vessels by using micro-mechanical manufacturing technology and shape memory alloy drives. Functions such as diagnosis, in vivo mic...
