Description
Technical field
This utility model relates to medical instruments field, relates in particular to a kind of capsule endoscope system that is applicable to Narrow-Band Imaging in digestive tract.
Background technology
Capsule endoscope (capsule endoscopy), is a kind of endoscope of making capsule shape, and it is for checking the Medical Instruments of human body intestinal canal.Capsule endoscope can enter human body, for spying upon the health status at human body the intestines and stomach and esophagus position, can be used to help doctor to diagnose patient.
One of endoscopic main purpose is to find as far as possible in early days tumor, but use the wide glistening light of waves to the emphasis effect of the slight change of mucosa superficial vein or mucous membrane tissue form not obvious, for strengthening the performance people of this diagnosis, from improving the imaging performance aspect of endoscopic system, made a lot of effort.Narrow-Band Imaging (Narrow Band Imaging) is a kind of optical imagery enhancement techniques, by reducing the spectrum of adjacent band, contacts, and the tissue signature of depth direction can be replicated out more clearly.Can strengthen the observation to the microstructure pattern of mucomembranous surface, accelerate the difference diagnosis to the tumor of gastrointestinal system mucomembranous surface and non-tumor simultaneously.For example, special 415nm and the narrow glistening light of waves of 520nm that meets mucous membrane tissue and hematochrome spectral characteristic that adopt of Narrow-Band Imaging endoscopic system, by strengthening the contrast properties of image, has improved the identification to early carcinomatous change tissue greatly, there is the effect identical with biopsy, be called as " optical biopsy ".Each monochromatic image signal, through colored reforming unit, makes blood capillary network and microstructure pattern display with the form of coloured image.For traditional endoscopic system, adopt shortwave light source narrow emission just can improve the ability at the blood capillary networking of describing meticulous mucomembranous surface like this.
Current narrow band imaging large-scale application in plug-in type endoscope.Capsule endoscope emerges more than ten year, is called the direction of 21 century endoscope's development, but cannot realizes the one of the main reasons that biopsy function is generally acknowledged its application of restriction of medical circle by medical circle.From using method, say, due to first generation capsule endoscope, with peristalsis of the digest tract, passive type advances after entering digestive tract, and the uncontrollable capsule endoscope of doctor carries out careful observation at suspected abnormality place, so narrow band imaging can not be applied on capsule endoscope.
As can be seen here, in the body of capsule endoscope, position observation is the problem that need to solve present stage, but there is no at present the capsule endoscope system of a kind of realization " optical biopsy ", to meet the detection needs of clinical medicine to digestive tract disease.
