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, a capsule endoscope system with a portable positioning device includes a capsule endoscope 1, an extracorporeal workstation 2 and a portable magnet array 3; the capsule endoscope 1, an extracorporeal workstation 2 and a portable magnet array 3 pass magnetic field Induction and wireless signal transmission form a system.

[0036] Such as figure 2 As shown, the capsule endoscope includes a capsule housing, a lighting device 18, an optical lens 17, an image sensor 12, a pH sensor 113, a circuit control device 13, a magnetic control switch 110, a magnet 5, a battery 14, and a radio frequency transceiver module 112 And antenna 16;

[0037] The lighting device 18, optical lens 17, image sensor 12, pH sensor 113, circuit control device 13, magnetic control switch 110, magnet 5, battery 14, radio frequency transceiver module 112 and antenna 16 are all fixed in the capsule Inside the speculum housing; the capsule housing is cylindrical, with a transparent...

Embodiment 2

[0042] The capsule endoscope system with a portable positioning device is the same as in Example 1. 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 each pocket contains 0-6 magnet magnets according to need or not to form a portable magnet array.

Embodiment 3

[0045] In actual use, the subject takes figure 2 After showing the capsule, lie down image 3 In the medical electric bed shown, the doctor's console controls the five-dimensional motion platform and the magnetic head. The magnetic field generated by the magnetic head controls the built-in magnet in the capsule endoscope, thereby controlling the capsule endoscope in the body to any position in the digestive tract for observation, and at the same time according to the actual detection If you need it or not, choose to turn on the pH sensor to detect the pH value at this location. When the doctor judges that the pH value detection capsule needs to stay in a certain position for timing pH value, you can put on a vest or belt for the subject. Adjust the position and number of magnets in the vest or waistband to make the magnetic field generated by the portable magnet array of the vest or waistband reach the best distribution. This magnetic field distribution should be able to mainta...

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, and in particular to a capsule endoscope system containing a portable positioning device suitable for use in the digestive tract. Background technique [0002] Capsule endoscopy (capsuleendoscopy) is an endoscope made into a capsule shape. It is a medical instrument used to examine the human intestines. The capsule endoscope can enter the human body to observe the health conditions of the human intestines, stomach and esophagus, and can be used to help doctors diagnose patients. [0003] The capsule endoscope 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" for tourists; tiny fibers can be used to strengthen the human heart artery; 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...
