Abstract

A photoelectric integration three-dimensional colposcope is suitable for auxiliary diagnosis and image management of vulva, vagina and cervical diseases in the gynecology. An LED cold light source diaphragm, a stereoscopic microscope and a digital camera constitute a stereo-micrography optical system together, an objective lens of the stereoscopic microscope is aligned to a focus of a patient under irradiation of the LED cold light source diaphragm, changes of epitheliums and blood vessels, which cannot be seen by naked eyes, can be observed three-dimensionally through the objective lens, the digital camera is used for converting optical signals under the lens of the stereoscopic microscope into digital signals through a high-resolution color CCD picture pick-up system, pictures are displayed on a display through communication with a host, and the pictures are synchronously displayed on the stereoscopic microscope and the display in real time. The photoelectric integration three-dimensional colposcope has the advantages that the perfect stereo-micrography optical system is provided, stereoimaging is achieved, color resolution is high, true color fidelity is high, stereoscopic impression is strong, and the depth of field is ultra large; moreover, a colposcope image processing system with strong functions is provided.

Description

A kind of optoelectronic integration 3 D stereo colposcope

Technical field

The present invention relates to a kind of gynecological armarium, especially a kind of optoelectronic integration 3 D stereo colposcope.

Background technology

The colpomicroscopic clinical practice history of existing more than 70 year, from " Optical colposcope " of hand-held optics " magnifier ", binocular vision, vagina image is presented to " electronic colposcope " monitor through video camera, to " digital electronic colposcope " that numeral camera system is combined with Computer Image Processing, colposcopy is checked and is diagnosed pudendum, vagina, cervical lesions to have important value, especially cell detachment cytolgical examination is positive, in perusal, be difficult to again definite suspicious lesions district, under colpomicroscopic guiding, biopsy can improve positive rate greatly.Cytolgical examination coordinates colposcopy, the diagnosis to early cervical carcinoma, and real is one of effective ways.

Colposcope is from hand magnifier, to binocular optical mirror, develop into present stage and use more digital electronic colposcope, in recent years, electronic colposcope has occupied considerable status in Gynecological cervical inspection, but along with application deepen continuously and to checking the raising of accuracy requirement, electronic colposcope expose many defects, when clinical use, find, electronic colposcope resolution is low, and female genital tract cervix uteri mouth, vagina, pudendum is stereochemical structure, there is the depth of field, it is not high that existing digital electronic colposcope can not solve the low definition being directed at of resolution well, imaging exists does not have the depth of field, there is no 3 D stereoscopic image, the not high variation that can not find in time cervix uteri blood capillary when observing trickle pathological tissues and blood capillary of resolution, also very easily cause the phenomenon of failing to pinpoint a disease in diagnosis in cervical carcinogenesis early stage, therefore can not obtain satisfied effect.

Electronic colposcope in the past adopts digital vedio recording to gather image and observes by display, is subject to its resolution of technical limitations can not reach the requirement of clinical diagnosis, still will just can accurately provide clinical diagnosis report by the observation under microoptic at present.Hospitals at Present all reduces misdiagnosis rate in colposcope diagnosis, so the colpomicroscopic development of optical microscope system is a kind of trend.

Summary of the invention

In order to overcome for using the low definition being directed at of resolution of digital electronic colposcope not high at present, imaging existence does not have the depth of field, there is no the problem of the aspects such as 3 D stereoscopic image, the invention provides a kind of by optics and electronics perfect adaptation, existing perfect stereomicroscopy optical system, has again the optoelectronic integration 3 D stereo colposcope of powerful colposcope image processing system.

The technical solution adopted for the present invention to solve the technical problems is: a kind of optoelectronic integration 3 D stereo colposcope, is applicable to auxiliary diagnosis and the image management of gynecological's pudendum, vagina, cervical disease.Comprise main frame, display, stereomicroscope, digital camera, LED cold light source aperture, casing, printer, foot switch, joystick, universal turning bench.LED cold light source aperture, stereomicroscope, digital camera form stereomicroscopy optical system jointly, digital camera is connected to stereomicroscope rear, LED cold light source aperture is connected to the place ahead of stereomicroscope, be enclosed within the outside of object lens, stereomicroscopy optical system is fixed in casing by universal turning bench, can 360 degree rotation, the flexible three-dimensional micro optical system of easy on and off.One of data connecting line I is connected on digital camera, and insert in main frame USB interface below other end, and main frame communicates; One of data connecting line II is connected on LED cold light source aperture, and insert in main frame USB interface below other end, and main frame communicates.Under LED cold light source aperture irradiates, the object lens of stereomicroscope are aimed at patient's focus, by eyepiece, can 3 D stereo observe epithelium that naked eyes can't see and the variation of blood vessel, digital camera is by high-resolution color CCD camera system, optical signalling under Stereo microscope camera lens is converted into digital signal, by communicating by letter with the connection of main frame, be presented on display, the image real-time synchronization on stereomicroscope and display shows.Input equipment, foot switch, joystick compounding practice, to the image collecting amplify, dwindle, closely gather, far gather, freeze, contrast, preservation, deletion, printing function.Light source switch is controlled the opening and closing of LED cold light source aperture light source, according to the light source that needs scalable LED cold light source aperture of brightness, regulate " on ", D score, " left side ", " right side " knob, can control respectively the Si Ge region, upper and lower, left and right of light source, can make the brightness of light source increase or reduce, to meet the needs of zones of different image acquisition.

The invention has the beneficial effects as follows, it is easy to operate, powerful, optoelectronic integration perfect adaptation, existing perfect stereomicroscopy optical system, three-dimensional imaging, it is high that color separation is distinguished, color rendition degree true to nature, third dimension is strong, and depth of field overlength has again powerful colposcope image processing system.
