Invention field and background

The present invention relates to characterize with radiationless electromagnetic transducer the endoscopic system of in-vivo tissue.

The influence of cancer is very big.Although expended a large amount of financial resources and manpower, the medical science target of early discovery malignant tumor still fails to realize.Though if known a lot of cancer early discovery is treatable, owing to lack reliable screening procedure, cause to find and to treat these cancers.

There is various ways in the endoscope that uses at present.For example, usually with the different colonic diseases of colonoscope diagnosis.For the operator, the far-end of representative colonoscope comprises light source, video chip and suction channel.But these elements all contact by ensconcing steel wire in the musical form pipeline and passage and colonoscope near-end.Far-end is inserted patient's rectum, can operate along colon length.Colonoscope enough can be inserted patient's colonic deeply, make far-end enter patient's caecum.Also can handle the colonoscope top and enter terminal ileum by ileocecal valve.

Colonoscope only provides the visual pattern of the colon regions that is directly adjacent to light source and video chip, has to the visual information of fraction colon regions at any given time.Usually determine the infringement of patient's colon by the whole colons of propelling property ground perusal, this process is brought misery for the patient.Yet the single colonoscopy is not enough to determine the source of RCH usually, and this source is generally sporadic, preferably locatees through observing whole colons after a while under many circumstances.

When making colonoscopy, the various adnexaes of colonoscope can carry out the minor operation operation, as biopsy.

The splanchnoscopy of small intestinal also comes out.For example, authorize the United States Patent (USP) 5 of Shan, 984,860, be entitled as " Pass-throughduodenalenteroscopicdevice (by duodenal intestinal mirror device); " its disclosure is attached to herein by reference, describes absorbable tether intestinal mirror camera, utilizes natural small intestinal contraction wave to impel it to pass through small intestinal with the speed that is same as any other object therein.Camera is included in the light source of its front end.Be enclosed within camera lens and light source outer be transparent inflatable bladders, be used for the small intestinal in expansion next-door neighbour camera the place ahead lightly, so that better the observation.When camera moved by small intestinal, path communication channel and light source cable launched in the camera back by aperture.After moving through small intestinal, optical cable separates automatically, and optical cable is withdrawed from from the harmonization of the stomach intestinal.Camera continues by large intestine, by patient's rectum.

Though above-mentioned endoscope can provide the instrument that enters and see the gastrointestinal tract part, can not provide the method that detects not obvious visible gastrointestinal disease.Specifically, they do not provide the method with invisible tumor-localizing and discriminating.Usually, with the naked eye be easy to locate big tumor.Yet, in the time can not with the naked eye finding tumor with sense of touch, for the success of subsequent procedures and the success of other form of therapy, must manage to be located in the tumor concealment phase.

Similarly, pulmonary carcinoma all is the major causes of death of cancer in the masculinity and femininity of Western society.Before diffusing to lymph node or other organ, if early discovery and treatment, survival rate was about 42% in 5 years.Yet, seldom early discovery.5 years survival rates in all pulmonary carcinoma stages amount to the factor that is about low 3 times of 14%-.

When symptom occurring, most of patients is just diagnosed, as carrying out bronchoscopy with the endoscope that is designed for lung especially.For example, the macroscopy bronchial wall, desirable small pieces tissue carries out biopsy.Perhaps, can carry out aspiration biopsy from lung taking-up cell by inserting a needle between the rib.Perhaps, undergo surgery resection organization for biopsy.The diagnosis of malignant tumor is carried out in laboratory usually, uses the feature of microscopy cell at the biopsy samples of excision.

Yet, the biopsy diagnosis that in laboratory, carries out and have following inherent defect based on the subsequent operation of laboratory biopsy:

I. biopsy is carried out when symptom occurs usually, and cancer is in late period;

Ii. biopsy may be taken from the tumor near zone, is not tumor itself, the false negative result that leads to errors;
