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

[0035] Such as figure 1 As shown, the capsule endoscope system containing the portable positioning device 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 pass through the magnetic field Induction and wireless signal transmission form a system.

[0036] 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;

[0037] 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 housing; the capsule...

Embodiment 2

[0042] The capsule endoscope system including the portable positioning device is the same as in Example 1, and the LED lighting device is a green 520nm LED (purchased from Chicago Miniature Lighting, LLC, model CMDA5AG7D1S).

[0043] 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

[0045] 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 built-in magnet 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 value 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 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 distributi...

Abstract

The invention relates to the field of medical instruments and provides a capsule endoscope system with a portable positioning device. The system comprises a capsule endoscope (1), an in vitro workstation (2), and a portable magnet body array (3), which together form a system through magnetic field induction and wireless signal transmission, wherein the portable magnet body array can be adjusted according to practical to be observed position, and solves the problem that a current capsule endoscope can not be timed and positioned conveniently, safely and effectively; through integration of a pH value sensor, the regular pH value detection for specific parts of an alimentary canal is realized; meanwhile, a narrow-wave LED light source lighting device can enhance the observation for microstructure models on surfaces of mucous membranes and accelerate the difference diagnosis for tumor and non-tumor on the surfaces of the mucous membranes of a gastrointestinal tract system.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a capsule endoscope system with a portable positioning device suitable for use in the digestive tract. Background technique [0002] Capsule endoscopy is an 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 different from ordinary capsule medicine, but It is a tiny video camera designed ...
