Description
Technical field
This utility model relates to medical machinery field, and espespecially a kind of endoscope and endoscope extend imaging device.
Background technology
Endoscope is a kind of Optical devices, human viscera organ can be inserted, the tissue morphology of human viscera organ is observed directly from human body, be widely used in the Diagnosis and Treat in digestive tract, urology department, lung section, gynecological, department of eye, orthopaedics, have the history of more than 200 year till now from its appearance.Along with the development of science and technology, the kind of endoscope and level have had the development of advancing by leaps and bounds, and develop into fujinon electronic video endoscope and ultrasonic electronic mirror from rigid endoscope, flexible endoscope.
Flexible endoscope, with the fiber optic conduction light source of softness and image, is called fibre optic endoscopes.Main species has Gastrointestinal Endoscopes, lung mirror, renal calculus mirror etc.Endoscope grows up along with fibre-optic appearance, and fibre optic endoscopes divides head end (doctor's hand-held manipulation end), far-end (inserting internal organs end) and sweep composition.Sweep is the soft sleeve pipe of sealing, inside has two kinds of optical fibers light beams, light guide bundles and coherent fiber bundle, is respectively used to illumination and imaging.In general, endoscope also has service aisle, to insert surgical instruments, such as biopsy forceps, so want sleeve pipe little, and service aisle is large.For convenience of detecting and operation, endoscope is towards the future development of ultra-fine footpath (diameter of gastrointestinal sight glass is 7.9 to 12.8mm, and in recent years occurs the endoscope of observable deep thromboembolism and renal calculus, and diameter is 0.19mm).
When carrying out " biopsy " (biopsy), need to cut in patient body, clamp to get or pierce through etc. and take out biopsy body, this is most important part in Diagnosis pathology, thus observe detection and accurately pincers to get biopsy body very crucial.But, consult Fig. 1, show the use schematic diagram of existing endoscope; As shown in Figure 1, some biopsy body 4 ' not only little but also position away from cavity lane.As shown in Figure 2, the diameter of the sleeve pipe 1 ' of existing endoscope is too large, its peripheral channel 6 ' can only be extend into, extend adjacent tissue, biopsy direction is pointed in existing endoscopic biopsy passway, biopsy forceps biopsy tissue after puncture needle 7 ' punctures, biopsy forceps clamps the process of getting, and endoscope cannot observe.If add, biopsy body is not on tract, but it is inner away from the tissue of tract, illumination and the visual range of endoscope are exceeded, the process of now biopsy forceps protractor biopsy body relies on very much the blind of doctors experience to get process, may clamp owing to not observing inner case and get normal tissue site, can not get clear and definite histopathology specimen, affect clinical diagnosis and treatment.
