Description

A kind of gynaecology's vaginal dilator

Technical field

The present invention relates to a kind of gynaecology's vaginal dilators, belong to gynaecology's technical field of medical equipment.

Background technique

During gynecologial examination, it generally can all use and arrive colpectasia equipment, and vaginal dilator is also in the process Main equipment reaches expansion effect by vaginal dilator, to realize the direct observation to intra focal;Due to existing expansion yin The expansion structure of device is mostly screw structure, and medical staff needs both hands operation that could complete to fix, and whole process is relatively complicated, It also wastes time simultaneously, therefore these all have much room for improvement, while in relative region, medical facilities are limited, traditional colpectasia Equipment only has the function of expanding, and needs additionally to use lamp source when checking vagina inside, but outside lamp source shadow surface is narrow It is small, so that doctor's observation is unintelligible, while can not observe comprehensively.In addition, traditional vaginal dilator kind of drive is mostly nut and screw rod Transmission, it is cumbersome, it wastes time, increases the sense of discomfort of patient, and screw rod is not easily cleaned later with nut use, is easy residual It stays, breed bacterium, the adverse consequences of some infection inflammations is caused to patient, it is serious also to cause gynaecological disease, such as vaginitis, Very big injury can also even be generated to the psychology of patient.

Summary of the invention

The purpose of the present invention is to provide a kind of gynaecology's vaginal dilators, to solve the problems mentioned in the above background technology.

To achieve the above object the invention adopts the following technical scheme: a kind of gynaecology's vaginal dilator, including handle, fixed plate And movable fagging, transmission parts are equipped on the handle, the fixed plate is set to above handle, is equipped in the rear end of fixed plate Observation panel can achieve the purpose of direct-view lesion by observation panel, the intra focal structure of patient be observed convenient for doctor, to patient Rationally accurately judgement, the movable fagging is made to be set to below fixed plate by shaft, reach by the rotation of movable fagging To the purpose for expanding vagina, drug feeding pipe, arc plate and rack gear are equipped on the movable fagging, the drug feeding pipe is set to flexible staybolt Below intralamellar part, it can be easily drug delivery at sufferer, improve practicability, the arc plate is set to movable fagging bottom, and circular arc Plate one end is inserted into handle inner, effectively prevents transmission parts and rack gear is exposed outside, avoid the growth of bacterium, described Rack gear is set on the right side of arc plate, and rack gear is engaged with transmission parts, run smoothly, easy to operate.

Preferably, the transmission parts include gear and turntable, and the gear is set to handle inner by shaft, and described turn Disk is set to the outside of handle, and the turntable is connect with gear by pin shaft, the rack and pinion tooth engagement, using gear and tooth Item transmission, runs smoothly, easy to operate, and does not need extra power to guarantee its operation, economizes on resources.

Preferably, the front end of the fixed plate and movable fagging is semicircle, which is convenient for fixed plate and movable fagging Preferably insertion intravaginal reduces resistance when entering, shortens the time of operation, mitigate the sense of discomfort of patient.

Preferably, the observation panel is circle, and a circular convex lens is equipped in the observation panel, can using convex lens To amplify patient's intra focal structure, so that observation is more clear, while while using light-illuminating, convex lens also has The effect of optically focused and scattering light, therefore can not only realize and be clearly viewed in the case that light is weaker indoors, while When using portable lamp light, light can be scattered, so that shadow surface is wider, it is more complete clear that doctor observes lesion, in institute The side for stating convex lens is equipped with protrusion, is equipped with the groove of one with the male cooperation, institute in fixed plate rear end corresponding position It states convex lens to be movably hinged by protrusion and the fixed plate, so that convex lens can be around protrusion rotation, the convex lens is removable It unloads, so that more convenient cleaning disinfection after the completion of detection.

Preferably, the convex lens is the plano-convex lens of single side male structure, and plano-convex lens can pool point light source flat Row light plays good amplification.

It is further preferred that being mentioned in the case where being equipped with LED illumination lamp on the inside of the convex lens light being weaker indoors For light source, convenient for the more complete intra focal for clearly observing patient, it is equipped with button cell in the handle and control LED shines The switch of bright lamp, the LED illumination lamp are connect by conducting wire with battery, and doctor can pass through according to the degree of strength of indoor light It switchs to control the closing of LED illumination lamp, and provide the energy using button cell, take up space very little, is conveniently replaceable.

Compared with prior art, the beneficial effects of the present invention are:

1, it is driven, is run smoothly using wheel and rack, it is easy to operate;

2, arc plate is had in movable fagging, it is exposed outside to effectively prevent wheel and rack, avoids bacterium It breeds;

3, drug feeding pipe can be easily drug delivery at sufferer, improve practicability;

4, convex lens is set in observation panel, patient's intra focal structure can be amplified using convex lens, so that observation is more clear It is clear;

5, clearly observation is realized in the case where LED illumination lamp being installed on the inside of convex lens light being weaker indoors, is made It is more complete clear that doctor observes lesion.

In short, the configuration of the present invention is simple, runs smoothly, it is easy to operate;Arc plate is had in movable fagging, it is effective anti- Stop that wheel and rack is exposed outside, has avoided the growth of bacterium;And facilitates observation illness, and easily can be by drug feeding pipe Drug delivery at sufferer.
