Embodiment 1

[0043]A magnetically controlled non-contact gastroenteroscope capsule, including a flexible tube and a capsule containing medicine, one end of the capsule is provided with three magnets, and the three magnets are connected to the capsule through silica gel, and a patient is provided with a The same number of three coils, the coils are used to generate gradient magnetic field and uniform rotating magnetic field, through the gradient magnetic field and uniform rotating magnetic field to control the movement direction of the three magnets, one of the magnets controls the movement of the capsule, and the other two magnets are used to puncture The capsule realizes drug administration, so as to achieve the purpose of controllable running direction of the capsule gastroenteroscope and targeted drug therapy.

[0044] The reason for designing three magnets in the present invention is that the degree of freedom of movement can be achieved through at least one magnet, but the degree of fr...

Embodiment 2

[0046] Based on the design principle of Embodiment 1, wherein the three magnets include magnet one, magnet two and magnet three, magnet one is connected to the end of the capsule, magnet two and magnet three are symmetrically arranged around magnet one as the center of magnet one On both sides, the first magnet, the second magnet and the third magnet are located at the same end of the capsule.

Embodiment 3

[0048] Based on the design principle of embodiment 2, described magnet one, magnet two and magnet three all adopt micro-magnets, wherein the specific arrangement of three magnets is as follows:

[0049] Such as figure 1 As shown, magnet 2 and magnet 3 are arranged at both ends of silica gel strip 1 at 180°, and fluorescent substances are arranged in the middle of silica gel strip 1; silica gel strip 2 is perpendicular to silica gel strip 1, and magnet 1 is arranged on silica gel strip 2; silica gel strip 3 Also perpendicular to the first silicone strip, capsules are arranged on the third silicone strip; the second magnet and the third magnet are provided with needle points in the same direction as the capsules.

[0050] The S pole of magnet 1 is facing the capsule, and the N pole of magnet 1 is far away from the capsule relative to the S pole; the magnetic poles of magnet 2 and magnet 3 are opposite, that is, the N poles of magnet 2 and magnet 3 are facing the fluorescent subs...

Abstract

The invention discloses a magnetic control non-contact capsule gastrointestinal endoscope which comprises a hose and a capsule body containing medicine, wherein three magnets are arranged at one end of the capsule body and connected with the capsule body through silica gel, three coils with the same number as the magnets are arranged outside a patient body, the coils are used for generating a gradient magnetic field and a uniform-intensity rotating magnetic field, moving directions of the three magnets are controlled through the gradient magnetic field and the uniform-intensity rotating magnetic field, one magnet controls the capsule body to move, and the other two magnets are used for driving the capsule body to rotate and crushing the capsule body to achieve drug delivery. The capsule gastrointestinal endoscope is particularly suitable for examination of digestive system diseases, the uniform-intensity rotating magnetic field is used for controlling the multiple small magnets installed in the capsule gastrointestinal endoscope in a patient body, and therefore the advancing direction and posture of the capsule gastrointestinal endoscope are changed to achieve the purposes of beingcontrollable in running direction of the capsule gastrointestinal endoscope and targeted drug treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a magnetically controlled non-contact gastroenteroscope capsule. Background technique [0002] With the improvement of living standards, the change of social environment, and the change of diet structure, human beings suffer from more and more types of diseases, and diseases of the digestive system are even more diverse. At present, for the diagnosis of digestive system diseases, traditional clinical in-vivo inspection equipment includes gastroscopy and colonoscopy. Among them, the traditional gastroscope extends into the stomach through a long metal tube and a mirror installed at the end, and then on the path of the gastroscope, the doctor can observe the diseases of the esophagus, stomach, duodenum and other parts, but the mirror During the march, it was easy to puncture body parts inside the patient, so it was discarded. In the later stage, capsule-type gastroscopes ...
