Abstract

The utility model relates to a disposable double-flap vaginal speculum of a smoke-pumping type. An upper expansion arm and an upper blade are connected into a whole, and a lower expansion arm and a lower blade are connected into a whole; the upper expansion arm and the lower expansion arm are hinged around a shared pin shaft and are positioned by a positioning rod, and the anterior borders of the upper blade and the lower blade are of a round duckbilled structure without sharp edges; a smoke-pumping tube communicated with a smoke-pumping device is arranged at the inner side of the upper blade, and the upper blade and the lower blade are provided with elastic silicone sleeve flaps or elastic winglike flaps or concertina folding flaps. In the utility model, the anterior borders of the upper blade and the lower blade are of the round duckbilled structure without sharp edges so as to avoid contact damage and bleeding and be safe and reliable; the smoke-pumping tube can remove fulgurated smoke generated in an operation so as to have a clear visual field and prevent environment pollution, and the flaps at both vaginal side walls can prevent the vaginal side walls from being falsely damaged by an electrode and are beneficial to pump and remove the fulgurated smoke generated in the operation.

Description

Disposable use smoke-discharging type double-protective wing vaginal dilator

Technical field

This utility model relates to a kind of gynecological medical apparatus and instruments, particularly a kind of disposable use smoke-discharging type double-protective wing vaginal dilator.

Background technology

The disposable vaginal dilator of department of obstetrics and gynecology is in clinical practice history of existing more than ten years, and in recent years, along with popularizing rapidly of electronic colposcope, the positive diagnosing rate of woman uterus disease rises very fast.Some patient wherein need carry out the operation on cervix treatment, and " LEEP " (ring electrode precancerous lesions of uterine cervix ring cutting art) operation is exactly one of modal clinically art formula at present." LEEP " art be unable to do without the good exposure in the operating field and the visual field with wherein its operation on cervix is the same.And the employed annular electrode of " LEEP " art is bigger, easily traditional vaginal dilator up and down blade open that the back forms, the vaginal wall surface that the left and right sides does not have a shield is caused and is burnt; The not only unhealthful but also fuzzy sight line of irritating smog of fulgerizing in the art and being produced.

Traditional vaginal dilator all is to adopt " closed shape is protruding chews " structure, and the anterior top when promptly blade is closed up and down is closed together mutually and chews point for circular arc.Often find that from the situation of clinical use circular arc chews point when rotten to the corn cervix uteri has appearred in contact, duck chews up and down the sheet leading edge circular arc top patient's cervix uteri of damaging easily and causes bleeding, and directly influences the inspection treatment of surgical doctor.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of disposable use smoke-discharging type double-protective wing vaginal dilator.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of disposable use smoke-discharging type double-protective wing vaginal dilator, and last expansion arm and blade fuse, and following expansion arm and lower blade fuse; Last expansion arm is hinged around total bearing pin with following expansion arm, and relies on the locating rod location.The leading edge of blade and lower blade is chewed the shape structure for duck slick and sly, no seamed edge, and when blade and lower blade closed up, the leading edge of blade and lower blade was the both sides closures, and the centre has a long and narrow slyness of Folium Salicis Babylonicae shape to put down to chew;

Be provided with the smoke extracting tube that is connected with fume extracting device in the blade inboard; Blade and lower blade are equipped with elastic silica gel sleeve flap or elasticity aliform flap or concertina fold flap;

Described elastic silica gel sleeve flap is sleeved on the closed blade and the outside of lower blade with tightening, and elastic silica gel sleeve flap two ends are provided with the ring of circular cross section; The tubular flap district in the blade and the lower blade outside is the concave shape structure, the surface in tubular flap district is the coarse surface layer of blunt round sand shape, the size of elastic silica gel sleeve flap can guarantee that it is sleeved on the closed blade and the concave shape tubular flap district of lower blade, the concordant smooth no concave-convex with the outer surface of blade and lower blade of the elastic silica gel sleeve flap behind the suit with tightening;

Described elasticity aliform flap comprises the type flap of bowing, clamshell type flap or offside type flap;

The type flap of bowing is installed in the cavity both sides between blade and the lower blade, one side the upper end of two elasticity aliform flaps each and closely being connected of blade respectively, one side the lower end of two elasticity aliform flaps each and closely being connected of lower blade respectively; The middle part in the elasticity aliform flap outside is provided with transverse concave groove, and the cavity between the blade is folding up and down;

The clamshell type flap is installed in the cavity both sides between blade and the lower blade, one side the upper end of two elasticity aliform flaps each and closely being connected of blade respectively;

Offside type flap is installed in the cavity both sides between blade and the lower blade, one side closely being connected of the upper end of a slice elasticity aliform flap and blade, the lower end of another sheet elasticity aliform flap closely is connected with the another side of lower blade;

When blade and lower blade were closed, the aliform flap closed at up and down in the cavity between the blade, and did not exceed the edge of cavity; When blade is opened up and down, elasticity aliform flap with trapezoidal developed surface with open after the cavity medial surface between the blade up and down match, short end is positioned at the rear portion of blade up and down, and long end is positioned at the front portion of blade up and down, and the maximum extension of blade and lower blade front end highly is not less than 45mm;

Described concertina fold flap is installed in the cavity both sides between blade and the lower blade, and the upper end of concertina fold flap closely is connected with two sides of blade, and the lower end of concertina fold flap closely is connected with two sides of lower blade.

The beneficial effects of the utility model are:

1. adopt narrow orifice shape circle to put down and chew, the leading edge of blade is slick and sly no seamed edge structure up and down, is the both sides closure when blade closes up up and down, and there is a Folium Salicis Babylonicae shape long and narrow space centre.When vaginal dilator contacts rotten to the corn position cervix uteri, can avoid the circular arc of traditional vaginal dilator to chew the contact bleeding due to trauma that point causes, made things convenient for doctor's diagnostic operation, safe and reliable.

2. be provided with the smoke extracting tube that is connected with fume extracting device in the blade inboard, can effectively get rid of the smog of fulgerizing that produces in the operation, keep the art open country to expose well, get a clear view, avoid irritating smog to fill the air, prevent the pollution of the environment protection medical personnel and patient's health.

3. on traditional disposable vaginal dilator architecture basics, increased bilateral vaginal wall flap structure, comprise elastic silica gel sleeve flap, elasticity aliform flap, concertina fold flap, all can effectively prevent vagina side-wall electrode accidental injury accident, and help to aspirate and get rid of the smog of fulgerizing that produces in the operation.
