For achieving the above object, technical scheme of the present invention is such: disposable self lighting vaginal speculum, use injection molding; By the inferior lobe of band handle and last leaf two parts of band adjustment sheet, cooperate composition by pivot pin and axis hole; It is characterized in that: the heel both sides of inferior lobe are arranged with at least two axis holes respectively, and two axis holes of every side are interconnected; Respectively establish a pivot pin in the heel both sides of last leaf; Pivot pin and axis hole cooperate, and form duck tongue shaped structure to be opened/closed; Have two slots before and after on the handle that infra blade root portion prolongation constitutes, the forward position in hole is the inclined-plane and constitutes monodentate; The form afterbody that constitutes at the prolongation of last blade root portion, the adjustment sheet that has at least 6 agnail sample tooth rows to constitute, according to the cooperation of pivot pin in different axis holes, it can insert the front or rear perforate on the handle respectively, the adjusting of folding angle between the upper and lower lobes is finished in the monodentate engagement on reversed acanthoid tooth row and the perforate forward position; The last leaf Herba sagittariae pygmaeae of inferior lobe Herba sagittariae pygmaeae length is no less than 1 centimetre, and the thickness that forms when upper and lower lobes closes up is also less and thin, is convenient to insert the vagina operation.

The edge part that constitutes form inferior lobe has a semi-circular groove hole, in be embedded with high-brightness semiconductor diode or bulb, the far-end at handle is provided with circular groove, internal fixation has two button button batteries, by electric wire, with self-lock switch, light source connect into the inspection lighting circuit.

Since the present invention adopted sublingua on the long structure of tongue, make it to meet the dissect physiology structure that arched roof length before and after the vagina, the degree of depth differ, vaginal mucosa fully exposed, be convenient to check.

Because the present invention has adopted self-contained lighting device, makes light be positioned at patient (examiner) the place ahead, doctor's health can not block light, does not need peripheral hardware light, does not have the illumination dead angle, is convenient to observe and operation.

Because the present invention has adopted two-part construction, makes vaginal speculum simple in structure, and is easy to use, easy to manufacture, cost reduces.

Because the structure that the present invention has adopted inferior lobe form offside the twin shaft hole to be set and to be interconnected, last leaf exchanges therein and can form the form and the visual field that varies in size, and makes it to have the characteristics that can be applicable to simultaneously that the age groups women checks.
