Description

The built-in digital imaging system of endoscope of gynecological

Technical field

The present invention relates to a kind of medical apparatus and instruments, particularly a kind of manufacturing technology field of accessory of the electronic digital endoscope medical image work station for gynaecologic vaginal, the integrated diagnosis and treatment of uterine cavity.

Background technology

Late 1990s, electronic colposcope is introduced China, and its manipulation check is convenient, and supporting picture and text are powerful, and what become the diagnosis and treatment of gynecological of hospital at different levels must the orchestration tool.Its imaging mode, after the specula distending was subjected to inspection face, by external light source, the inspection to cervix uteri, vaginal wall, diagnosis and treatment were finished in the visual field that the CCD image pick-up device exposes specula.The doctor need dispose the different model specula and adapt to the different human body specification requirement, and look-out station is limited to cervix uteri.Because metal specula reflective is strong, can present reflective speckle on the photo, has influence on shooting quality.

Hysteroscope occurs, and it can look at intrauterine physiology and pathological change straight, can carry out some intrauterine therapeutic operation techniques under sight glass.Its imaging mode adopts sight glass, light guide bundles, through light guide bundles light source is imported focal zone by external light source (as two lamp 150W5600K cold light sources), and amplifying back observation uterine cavity shape intrauterine by mirror body eyepiece high power has no abnormal or pathological changes.External CCD image unit is realized image transfer.The hysteroscope angle of visual field is 60 °, and because the decay of light guide bundles transmission light source is big, area of illumination is irregular, and eyepiece is observed and had certain limitation, enlarge and observe the in utero visual field, further improve image definition and have certain difficulty.

Summary of the invention
