Problems solved by technology

Capsule endoscopes have been available for more than ten years, and are known by the medical community as the development direction of endoscopes in the 21st century, but the inability to realize the biopsy function is one of the main reasons for restricting its application recognized by the medical community
[0006] In terms of usage, since the first-generation capsule endoscope enters the digestive tract and moves forward passively with the peristalsis of the digestive tract, doctors cannot effectively control the capsule endoscope to the site to be observed, let alone carefully observe the suspected lesion. , so these shortcomings limit the wider application of capsule endoscopy
[0007] It can be seen that the in vivo positioning observation of the capsule endoscope is a problem that needs to be solved at this stage, but there is no capsule endoscope system that can realize the above-mentioned multi-functions to meet the needs of clinical medicine for the detection of digestive tract diseases

Embodiment 1

[0033] Such as figure 1 As shown, a multifunctional capsule endoscope system suitable for the digestive tract includes a capsule endoscope 1, an in vitro workstation 2 and a portable magnet array 3; the capsule endoscope 1, in vitro workstation 2 and portable magnet array 3 A system is formed through the induction of the magnetic field and the transmission of wireless signals.

[0034] Such as figure 2 As shown, the capsule endoscope includes a capsule housing, an illumination device 18, an optical lens 17, an image sensor 12, a pH sensor 113, a circuit control device 13, a magnetic switch 110, a magnet 5, a battery 14, and a radio frequency transceiver module 112 and antenna 16;

[0035] Described illumination device 18, optical lens 17, image sensor 12, pH value sensor 113, circuit control device 13, magnetically controlled switch 110, magnet 5, battery 14, radio frequency transceiver module 112 and antenna 16 are all fixed in described capsule The inside of the mirror h...

Embodiment 2

[0040] A multifunctional capsule endoscope system suitable for the digestive tract, the rest is the same as that of Embodiment 1, and the LED lighting device is a green 520nm LED (purchased from Chicago Miniature Lighting, LLC, model CMDA5AG7D1S).

[0041] The portable magnet array is a belt with two pockets, and 0-6 magnets are placed in each pocket according to needs to form a portable magnet array.

Embodiment 3

[0043]In actual use, subjects take figure 2 After the indicated capsules, lay image 3 On the medical electric bed shown, the doctor console controls the five-dimensional motion platform and the magnetic head, and the magnetic field generated by the magnetic head controls the magnet built in the capsule endoscope, thereby manipulating the capsule endoscope in the body to observe at any position in the digestive tract, and at the same time according to the actual detection Whether it is necessary or not, choose to turn on the pH sensor to detect the pH value of this position. When the doctor judges that the pH value detection capsule needs to stay at a certain position to measure the pH value at a certain time, he can put on a vest or a belt for the subject. Adjust the position and number of magnets placed in the vest or belt to achieve the best distribution of the magnetic field generated by the portable magnet array of the vest or belt. This magnetic field distribution shoul...

Abstract

The invention relates to the field of medical instruments, and provides a multifunctional capsule endoscope system suitable for the interior of an alimentary canal. The multifunctional capsule endoscope system comprises a capsule endoscope (1), an extracorporeal workstation (2) and a portable magnetic array (3), wherein capsule endoscope (1), the extracorporeal workstation (2) and the portable magnetic array (3) form a system through the induction of a magnetic field and the transmission of wireless signals. The portable magnetic array can be adjusted according to a practical part to-be-observed, so as to conveniently and safely solve the problem that the conventional capsule endoscope cannot be timed and positioned; through the integration of a pH value sensor, regular pH value detection in a specific part in the alimentary canal is realized; a narrow band LED light source lighting device is adopted, so as to enhance observation of a microstructure mode on the surface of a mucous membrane, accelerate difference diagnosis of tumors and non-tumors on the surface of the mucous membrane of a gastrointestinal tract system.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a multifunctional capsule endoscope system suitable for regular positioning and observation in the digestive tract, having optical biopsy, and capable of recording pH values. Background technique [0002] Capsule endoscopy is a kind of endoscope made in the shape of a capsule, which is a medical instrument used to examine the human intestinal tract. Capsule endoscopes can enter the human body and are used to spy on the health status of the human stomach and esophagus, and can be used to help doctors diagnose patients. [0003] Capsule endoscopy actually shrinks the camera and implants a medical capsule to help doctors diagnose patients. A small capsule is a camera studio for exploring the human body, and may even become a "spaceship" that travels through the human body; tiny fibers can be used to strengthen the heart arteries of the human body; from the outside, it is not much dif...
