When the patient adjusts to different body positions, the lens will be directed to different positions to achieve shooting, thereby achieving all-round shooting of the human body, without the need for corresponding motion control, easy to use, cost-saving, and conducive to large-scale promotion and use.

[0003] Capsule endoscopy drug release technology is a technology that uses the special design of capsule endoscopes to wrap drugs in capsules and release drugs in the digestive tract as the endoscope moves. This technology can achieve precise positioning, accurate drug release, efficient absorption, non-traumatic and painless, and is widely used in the treatment of gastrointestinal diseases, such as gastric and duodenal ulcers, gastroesophageal reflux disease, intestinal inflammation, etc. Capsule endoscope is an endoscope made in the shape of a capsule. It is a medical instrument used to examine the human intestine. Capsule endoscopes can enter the human body and are used to spy on the health of the human stomach and esophagus. It is used to help doctors diagnose patients' digestive system diseases. Capsule endoscope working process: From the outside, it is not much different from ordinary capsule medicine, but it is a miniature camera used to spy on the health of the human stomach and esophagus. After the patient swallows it, the capsule moves along the digestive direction with the movement of the gastrointestinal muscles, takes images, and then transmits the images to the data transmission device tied around the patient's waist. A few hours later, the doctor downloads the images taken by the capsule to the computer, and the capsule is automatically excreted from the body within 24 hours. Traditional capsule endoscopes cannot achieve the drug administration function, and the drug positioning accuracy is not high. They can only deliver drugs into the digestive tract, but cannot accurately locate specific parts. The drug efficacy is not ideal, and some drugs are even wasted because they cannot reach the lesion site. Utility Model Content

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0023] In the drawings, the same reference numerals all refer to the same components.

[0024] Example 1

[0025] Reference Figure 1-3 The utility model provides an embodiment: an endoscopic capsule with a drug release function, comprising a head cover 1, a tail cover 2 and a shell 3, a camera module 4 is arranged on the inner side of the head cover 1, a rubber piston 5, a slide groove 6 and a bearing 7 are arranged on the inner side of the tail cover 2 from left to right, a pin 8 is arranged on one side surface of the rubber piston 5, and a radial magnet 9 is arranged on the inner side of one side surface of the bearing 7.

[0026] The head cover 1 and the tail cover 2 are both made of plastic material, and are semicircular in shape, with an arc-shaped groove in the middle. The head cover 1 and the tail cover 2 are spliced ​​and assembled with the outer shell 3, and the outer shell 3 is cylindrical in shape with a circular hollow in the middle. A drug release hole is provided in the center of the tail cover 3.

[0027] The housing 3 and the camera module 4 are spliced ​​and assembled, wherein the camera module 4 comprises a base and a CMOS camera. The housing 3 and the rubber piston 5 are spliced ​​and assembled, wherein one end of the rubber piston 5 is arranged in a semicircular arc shape and the other end is arranged in a cylindrical shape.

[0028] The rubber piston 5 and the latch pin 8 are fixedly connected, and the latch pin 8 is cylindrical. The rubber piston 5 and the slide member 6 are movably connected, and the slide member 6 is threaded, and a spiral groove is provided on one side surface.

[0029] The slide member 6 and the bearing 7 are fixedly connected, and the bearing 7 is arranged as a cylinder. The bearing 7 and the radial magnet 9 are movably connected, and the radial magnet 9 is arranged as a cylinder.

[0030] Specifically, the structure is composed of a head cover 1, a tail cover 2, a shell 3, a camera module 4, a rubber piston 5, a slide groove part 6, a bearing 7, a latch 8 and a radial magnet 9 to form an endoscopic capsule with a drug release function. The head cover 1, the tail cover 2 and the shell 3 form an endoscopic capsule main structure with a drug release function, which is made of polymer materials. The head cover 1 is used for the camera module 4. The rubber piston 5 is pushed forward to release the drug through the internal baffle of the shell 3 and the capsule structure. The drug is released to the lesion through the drug release hole of the tail cover 2. The camera module 4 is loaded at the head position of the capsule head cover 1 and synchronized with the external display to display the specific situation in the intestine. The threaded slide groove of the slide groove part 6 is used to convert the magnetic force of the radial magnet 9 into forward thrust. The bottom magnetic drive is environmentally friendly and energy-saving in conjunction with the bearing 7. The rotation of the rubber piston 5 is limited by the latch 8, so that the rubber piston 5, the slide groove part 6, the bearing 7, the latch 8 and the radial magnet 9 form a drug release system, which effectively drives the movement of the capsule through magnetic control, and realizes the drug application function using the capsule endoscope.

[0031] Working principle: Through the external robotic arm device, the robotic arm rotates the external magnet clockwise to control the movement of the capsule. The camera module 4 inside the capsule synchronizes the image with the external computer. After the lesion is found through the camera module 4 and synchronized to the external computer, the capsule operates in the intestine, and the robotic arm rotates counterclockwise to release the drug. The endoscopic capsule with drug release function adopts magnetic drive control, which can accurately make the capsule reach the location of the lesion and realize precise drug administration.

[0032] Principle of drug release: The doctor finds the lesion through the real-time computer screen and controls the mechanical arm to rotate the external magnet counterclockwise. The external magnet drives the radial magnet 9 inside the capsule to rotate, and the slide groove part 6 rotates. The inner and outer sides of the bearing 7 respectively fix the shell 3 and the drug release system, so that the pin 8 collides with the baffle of the shell 3 to generate a force, and the rubber piston 5 is pushed out by the force to successfully release the drug. After the drug release is completed, the mechanical arm is controlled to rotate the external magnet clockwise. After the rubber piston 5 is retracted, the capsule continues to move forward until it is discharged from the body.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
