Description

A kind of anus colposcope

This utility model relates to a kind of inspection and treatment anus vagina device.

Be used in the hospital at present to check and treat that the horn anoscope of anus is additional a round end inner core, solving fragile anal canal skin of horn mouth sharp edge and mucosa problem, the utility model patent communique on March 12nd, 1992 disclosed a kind of " integral type anus colposcope ".This device lens barrel front end is tiltedly opened one oval mouthful, an oval mouthful edge is a round edge, the front side of round edge is expanded and is askew round end, make this mirror omit the round end inner core, the disome formula changes integral type into, more than two kinds of devices all need add light illumination, very inconvenient in use, easily the shading focus does not easily see the Chu Zaocheng mistaken diagnosis, and handy two handss are operated simultaneously increases medical worker's working strength, and is just more incompatible in the field boundary institute that does not have power supply.

The purpose of this utility model is: design a kind of anus colposcope, to solve prior art fragile anal canal when operating, vagina skin and mucosa, it is inconsistent to add light illumination light and sight line, easily shading, focus does not easily see the Chu Zaocheng mistaken diagnosis, handy two hand operateds, inconvenience, the field boundary that does not have power supply the deficiency that can't use.

This utility model is by lens barrel, handle and illuminator are formed, lens barrel myopia is horn-like, its preceding small end is oblique ellipticity opening, tiltedly the edge of oval opening is the round edge of 3.5 millimeters of thickness, handle is that hollow cavity constitutes battery case, the upper end is 30 degree angles and has female thread, optically focused bulb and screw-internal thread fit, illuminating ray and sight line are 20 degree angles, anode cooperates with the spotlight breech piece, handle, at its lower end lid and handle threaded engagement, the bottom end cover inner face has a copper sheet to cooperate with spring, and battery is paid the utmost point and is cooperated with spring, one slide switch is arranged on the handle external diameter, two lead-in wire two ends are connected in positive pole and switch respectively, pay the utmost point and switch room solid welding, there is an opening lens barrel and handle socket mating part inboard, handle and its tight fit.

The utility model has the advantages that be oblique ellipticity opening owing to designed the lens barrel small end, tiltedly the edge of oval opening is the round edge of 3.5 millimeters of thickness, when operation, be competent to advance and retreat-at will, can arbitrarily rotate, not fragile anal canal, vagina skin and mucosa have designed illuminator, spotlight light and sight line are 20 degree angles, light is consistent with sight line during use, is difficult for shading, and focus sees clearly Chu, made things convenient at the field boundary that does not have power supply and used, widely applicable advantage.

Description of drawings:

Fig. 1 is the colpomicroscopic structure sketch of a kind of anus;

This utility model most preferred embodiment is, be by lens barrel, handle and illuminator are formed, it is material that lens barrel adopts rustless steel, also can adopt plastics to make disposable use, lens barrel 4 near-sighted loud-speaker shapes, its preceding small end is oblique ellipticity opening 5, tiltedly the edge of oval opening 5 is the round edge 6 of 3.5 millimeters of thickness, the big end of lens barrel has handle socket, handle 1 is a material with plastics, handle 1 constitutes battery case for hollow cavity, and the upper end is 30 degree angles and has female thread, optically focused bulb 3 and screw-internal thread fit, battery 2 positive poles cooperate with optically focused bulb 3 afterbodys, bottom end cover 13 and handle 1 threaded engagement, the bottom end cover inner face has a copper sheet 12 to cooperate with spring 8, and 2 pairs of utmost points of battery cooperate with spring 8, one slide switch 9 is arranged on handle 1 external diameter, two lead-in wires 10,11 external diameter two ends are connected in anodal and 9 pairs of utmost points of switch and switch room respectively, and lens barrel 4 has an opening with handle socket 7 mating part inboards, handle 1 and socket 7 tight fits.
