Abstract
The invention provides a high-resolution breast duct endoscope optical system. The high-resolution breast duct endoscope optical system comprises a first lens group, a second lens group and an even number groups of image transfer lenses, wherein the first lens group comprises a first parallel flat plate, a planoconcave lens, a second parallel flat plate and a first convex lens which are sequentially adhered in the light incidence direction, and a diaphragm is plated on the face, adhered with the first convex lens, of the second parallel flat plate. The second lens group comprises a meniscus lens and a second convex lens which are sequentially adhered in the light incidence direction. Each group of image transfer lenses comprises two rod-like thick lenses, wherein the opposite faces of the rod-like thick lenses are respectively adhered with thin lenses, and the groups of image transfer lenses are 1:1 double telecentric image transfer lens groups. The high-resolution breast duct endoscope optical system uses a rod-like lens image transfer system instead of superfine light-guide fiber image transfer beams to transfer images, enables the breast duct endoscope image resolution to be improved from 30l p/mm to 60l p/mm, and meanwhile improves the edge view field resolution of a traditional breast duct endoscope.
Description
Technical field
The invention belongs to optical field, especially relate to a kind of high resolving power breast pipe mirror optical system.
Background technology
Whole world breast cancer incidence starts always in rising trend from late 1970s. The U.S. 8 women just have 1 people in throughout one's life and suffer from mammary cancer. China is not the country occurred frequently of mammary cancer, but unsuitable optimistic, and the rate of growth of China's breast cancer incidence but exceeds national 1～2 percentage point occurred frequently in recent years. Mammary cancer morbidity data displays in 2009 according to Cancer center of country and prevention and control of diseases office of the Ministry of Health announce for 2012: tumour registration area, whole nation breast cancer incidence occupies the 1st of female malignant, it is 42.55/10 ten thousand that female mammary gland cancer morbidity (rough and careless) whole nation adds up to, city is 51.91/10 ten thousand, and rural area is 23.12/10 ten thousand.
Mammary cancer has become the great public health problem of current social. From the nineties in 20th century whole world breast cancer deaths rate present downtrending; Tracing it to its cause, one is carrying out of mammary cancer screening, and the ratio of early-stage cases is increased; Two be carrying out of mammary cancer complex therapy, it is to increase curative effect. Mammary cancer has become one of noumenal tumour of curative effect the best.
Breast Guan Jing, also known as electronics mammary gland fibrescope, has replaced breast pipe radiography at present, has become the first-selected means of nipple discharge etiological diagnosis. Duct endoscopy operation is convenient, wound is little, directly perceived, effectively improve the diagnosis that in breast pipe, protuberance venereal disease becomes, simultaneously also can with the treatment with optimum breast pipe pathology, in the treatment of pathology Ru Guan Wicresoft as auxiliary in breast pipe mirror excision, plasma cell mastitis, breast pipe, tumour leads silk location etc.
The structure of breast Guan Jing comprises biography picture and light guide, shooting and the Lights section, image displaying part, image management and output part. Breast pipe mirror system comprises fiberscope, camera system, cold light source system, indicating system and computer control register system, feasible real-time collection static state and dynamically photologging.
Duct endoscopy is a diameter is the endoscopy of 0.75mm (0.6mm or 0.95mm), by ultra-fine light-guide fiber image bundles, lead light beam, small self-focus lens and camera lens forms, breast duct wall and the situation of pipe chamber secretory product can be observed by mammoscopy clearly, its color and luster, size, shape, smooth degree etc. can be described if any occupying lesion.Breast ductal cancer, lead intracanalicular papilloma, performance under duct endoscopy that conduit inflammation has its characteristic respectively, thus can make diagnosis accordingly. The other effect of breast conduit endoscopy be the biopsy that can carry out focus under duct endoscopy guides to obtain pathology make a definite diagnosis; Focus is carried out skin surface mark or by breast the underlying positioning guide wire of conduit mirror and be operation locate accurately; By breast Guan Jing to the treatment of benign disease in breast pipe.
Tradition duct endoscopy optical system transmits the image of object lens with ultra-fine light-guide fiber image bundles, as shown in Figure 1, ultra-fine light-guide fiber image bundles is approximately become, the about 30lp/mm of image resolution rate by the optical fiber arrangements of about 17 microns of 800～1200 optical fiber filament diameters.
