A kind of capsule gastroscopeTechnical field
The present invention relates to medical field, particularly relate to a kind of capsule gastroscope.
Background technology
" capsule endoscope " full name is " intelligent capsule digestive tract endoscope system ", also known as " Medical wireless scope ".Capsule endoscope front end is transparent spherical, and the inside is a Miniature digital camera machine and multiple flash lamp.Clear photograph can be taken in pitch-dark digestive tract, before Capsule Endoscopy, the first fasting of those who are investigated's palpus, after being somebody's turn to do " intelligent capsule " under clothes for patients, capsule is walked voluntarily in vivo because of digestive tract power, and photograph the image of harmonization of the stomach large intestine, small intestinal, image is by sensor one of being transferred to that patient carries with the in digital form recording equipment more bigger than medicated cigarette box.Whole process probably needs 8 to 10 hours, and period patient can leave hospital and normally work, lives.After time is up, patient only need send data logger back to, and doctor is according to nearly 80,000 photos in monitor, and check the pathological changes situation of esophagus, stomach, small intestinal, large intestine, finally, intelligent capsule will excrete automatically.
Application number be 201320159604.1 Chinese invention patent disclose a kind of capsule type gastroscope, there is capsule probe and image display, capsule is popped one's head in by video wire transmission video signal to smart mobile phone, but this technical scheme does not possess the function in adjustment stomach inside photographing region automatically yet.
Publication number is that the Chinese patent application of CN104688173A discloses a kind of capsule gastroscope changing shooting angle, by adding eccentric and Power Drive Unit, changing photo angle, adding the shooting angle of stomach inwall.But there is certain randomness in its mode changing photo angle, differs and photograph the every nook and cranny of stomach inwall surely.

Preferably, described housing is made up of inside and outside two-layer shell, and LED light source and photographic head are located between two-layer shell.
Preferably, described housing two ends are provided with a center of circle plane, and the radius of described center of circle plane is the half of described housing maximum radius.
Compared with prior art, the invention has the beneficial effects as follows:
(1) by photographic head and LED light source are located at housing one or both sides, greatly can improve the visual angle of photographic head, reduce to take pictures blind area;
(2) establish more than one auxiliary camera at microprocessor edge, be used for making up the blind area of taking pictures that middle photographic head may exist, realize real taking without dead angle;
(3) case side cross section is set as class ellipticity or class runway shape, resistance when capsule gastroscope moves in the intestines and stomach can be reduced, alleviate its injury to the intestines and stomach, particularly adopt the profile that cosine function curve is formed, be conducive to the motion of gastroscope the intestines and stomach from mechanics, optically can eliminate the dead angle of photographic head shooting, improve being uniformly distributed of light when LED light source irradiates, particularly cross-directional length is arranged to the 3-4 of vertical direction Breadth Maximum doubly, best results;
(4) micromotor is set in the housing, by the coverage of the Spin Control auxiliary camera of micromotor, accurately controls the position of the shooting of photographic head, understand the state of the intestines and stomach inside more comprehensively.
