Built-in colposcope realizing multiple imaging modes

Abstract

The invention discloses a built-in colposcope realizing multiple imaging modes. For the built-in colposcope, the amplification factor is continuously adjustable, meanwhile, various imaging modes (such as the white-light imaging mode, multi-spectrum imaging mode, fluorescent staining imaging mode and green-light imaging mode) are realized, the tested tissue is imaged through the different imaging modes, the multi-spectrum imaging mode and the fluorescent staining imaging mode provide the superfine-blood-vessel-level image with high contrast ratio distribution, the white-light imaging mode is used for common occasions, the use is convenient, for example, the white vinegar reaction and the iodine test technology can be adapted; a built-in amplification imaging unit is placed in the vagina, the work distance is adjusted according to the demands, and thus the amplification factor is adjusted; in order to not influence the sampling of biopsy forceps, a camera unit is arranged on the bottom of the built-in amplification imaging unit for matching with the built-in amplification imaging unit with small diameter, and the operation is not influenced. The built-in colposcope provides the first-hand blood vessel distribution information for the clinic, the biopsy accuracy rate is improved, and the misdiagnosis rate is reduced.

Description

technical field [0001] The invention relates to a medical imaging device, in particular to a built-in colposcope with multiple imaging modes. Background technique [0002] Cervical cancer is the most common gynecological malignancy, with approximately 520,000 new cases and 270,000 deaths worldwide each year. China is a country with a high incidence of cervical cancer in the world. There are about 150,000 new cases every year, of which about 53,000 people die, accounting for about 1 / 3 of the world's total. Therefore, the early diagnosis and prevention of cervical cancer has important practical significance. [0003] In 1925, German scholar Hans Hinselman invented the colposcope for cervical observation. It has a history of nearly 100 years. After the development of optical, electronic and photoelectric colposcope, it has become an indispensable instrument for cervical cancer diagnosis. [0004] In the development of colposcopy, the pursuit of higher resolution and clearer i...
