The illumination optics unit of lighting source and the illumination observation object for utilization from lighting source.
Background technique
In medical health field, predominantly meet for woman vagina, the vaginal speculum inspection of uterine neck and vaginoscopy with
The purpose of lower two aspects: one is to diagnose the necessary of vaginitis, cervicitis and screening cervical carcinoma to check；Secondly for observation uterine neck
Pipe mutosal pattern, purpose predominantly judge whether to ovulate, judge that the onset of ovulation and guidance become pregnant or practise contraception.As human diseases compose
Variation and people's raising that quality of life is required, crowd's incidence of vaginitis, cervicitis and cervical carcinoma show by
Under cumulative high trend, society pays close attention to the prevention and treatment of aforementioned diseases further.So far, due to being dissected by Lower Female Genital Tract
With the limitation of physiological characteristic, the more restriction due to the inspection utensil used by the good autonomous grasp of no practicability, cause yin
Road, uterine neck inspection can only be limited to health care institution and be implemented by medical worker, thus make vaginitis, cervicitis and cervical carcinoma
The caring of prevention and treatment, vagina and uterine neck cannot more positive, more convenient, more common implementation.By observing cervical canal mucus
Character and the aspect that instructs to practise contraception or become pregnant, the observation that similarly can be independently implemented by limitation above-mentioned and restriction, the women of child-bearing age
Only to the observation of the leukorrhea character of vagina outflow, it is not the observation of direct cervical canal mutosal pattern, is thus independently sentenced
It is disconnected whether to ovulate, judge that the onset of ovulation and guidance become pregnant or practise contraception and bring difficulty and uncertainty.In surgical operation frequently with
Lighting device, as shown in attached drawing 1 in prior art CN2516109Y, which is by upper duckbilled piece 11, lower duck
Mouth piece, handle press handle, upper lower lip connecting shaft composition, set miniature lighting lamp 16 in the rear side of upper duckbilled piece 11, however
When being performed the operation or being observed to vagina, which either dimensionally, in brightness or in uniformity can not expire
In the operation at sufficient vagina position.
