Description
Technical field
The present invention relates to a kind of disposable sterile vaginal dilator of tunnel type, belong to technical field of medical instruments.
Background technology
At present, disposable vagina expander is commonly used in clinical gynecologial examination, and current vaginal dilator is one very thin
Duck bill clip, doctor open whole folder after being placed on patient's vagina, are then gone to coordinate inspection with inspecting lamp or finger or instrument, when
It was found that during diseased region, in surgery procedure, smog can be produced in vaginal cavity, existing expander due to structure design not
Enough reasonable, smog is difficult to exclude in time, influences the diagnosis visual field, and doctor can only be operated with feel or experience, diagnosis
Process time is longer, and great pain is brought to patient, the disease for needing visual diagnostic, can cause to judge to be forbidden, easily lead
Operation is caused to occur unexpected, in addition, operation smoke cell fragment existing for 95% vapor and 5% particle shape forms, particle
Presence cause operation smoke to produce serious harm to health, medical personnel feel dizziness, headache, nausea etc. sometimes
Malaise symptoms.
Also occurs the vaginal dilator of internal illumination light source in the market, using dry cell as power supply, it is unfavorable to have for it
In the deficiency of sterilization, dry cell has the potential safety hazard of blast in patient's body.In addition, the vaginal dilator of prior art is also present
Following deficiencies：Regulation poor controllability between expansion leaf up and down, it is inconvenient during use, it is after upper and lower expansion leaf opens, patient is cloudy
The both sides up and down of road cavity wall can be very good to strut, but the cavity wall of the left and right sides there is a situation where to come together, and interference diagnosis regard
Open country, and smog can not be avoided in cavity to assemble, and structure design is unreasonable between expansion leaf up and down, reliability is poor during use,
Unexpected injury is easily caused, the size of upper and lower expansion leaf is long, easily blocks opening of the cervix, and its operating surface width is inadequate, restricts machine
Device people performs the operation or postoperative suture.
The content of the invention
It is an object of the invention to solve the deficiencies in the prior art, there is provided a kind of disposable sterile vagina of tunnel type expands
Prop.
The technical solution adopted for the present invention to solve the technical problems is：
The disposable sterile vaginal dilator of tunnel type, including upper expansion leaf, lower expansion leaf and push rod, the push rod top
End is provided with the governor motion for being used for upper expansion leaf being adjusted when operating, include arc light-guiding pillar located at lower expansion leaf with
Light source, the light extraction end of the light source are abutted with arc light-guiding pillar, and the upper expansion leaf, which is provided with, to be used to exclude smog in vaginal cavity
Smoke discharging structure, the smoke discharging structure is made up of connecting tube and smoke evacuation groove, and smoke evacuation groove both sides are provided with slide rail, upper expansion leaf provided with
The chute matched somebody with somebody, by the cooperation of slide rail and chute, smoke discharging structure with it is upper expansion leaf be detachably connected, smoke evacuation groove with it is upper expansion leaf it
Between form the smoke extraction chamber passed through for smog；
Also including auxiliary expanding mechanism, the auxiliary expanding mechanism is made up of the first expansion part and the second expansion part, first,
Two expansion parts are formed by enlarged portion, limiting section and department of assembly, and first and second expansion part is detachably connected by the cooperation between department of assembly
Connect, gathering or the opening of enlarged portion are realized by the cooperation between limiting section.
The vaginal dilator of prior art is provided with smoke exhaust pipe, is connected in expansion leaf, is connected with medical vacuum Negative pressure machine, inhales
Except caused smog in performing the operation in vaginal cavity, the flow of medical vacuum Negative pressure machine can generally meet clinical demand for ejectment, but by
It is not reasonable in the structure design of smoke exhaust pipe, it is small for the passage of smog circulation between its connecting portion and smoke evacuation portion, restrict smog
Exclude, cause smoke discharging effect undesirable, although the flow matches of medical vacuum Negative pressure machine is higher, the two flow differs
Cause, the service efficiency of medical vacuum Negative pressure machine is not high.The structure design of the present invention, formed between connecting tube and smoke evacuation groove larger
For smog circulation passage, the two flow can be with fabulous matching, and exhaust smoke level is big, and smoke discharging effect is good.
After upper and lower expansion leaf opens, the both sides up and down of patient's vagina cavity wall can be very good to strut, while aid in expanding
Mechanism can also strut the cavity wall of the left and right sides well, diagnosis broad view, while be advantageous to smog in cavity
Diffusion.
Preferably, the smoke evacuation groove side is additionally provided with some smoking ports, and the smoking port is respectively arranged on the top of smoke evacuation groove
And middle part, the chute top and smoke evacuation groove top portion are additionally provided with the locking mechanism of mutual cooperation, after smoke evacuation groove inserts chute, passed through

Provided with the 4th range of atomization.
Light is propagated inside expansion leaf, when from expansion leaf outgoing（It is emitted from the plastic material of expansion leaf into air
When）, according to the EM theory of light wave, if light is not reaching to total reflection angle with interface normal, although most of light can go out
It is mapped in air, but always has part light and can be reflected（Fresnel reflection）, the total direction of this part reflected light is rearward, to refer to
Xiang the direction of doctor's eyes, if just into doctor's intraocular, a high speck can be formed in the visual field, influences the sight of doctor
Examine；After setting range of atomization, the angle of back reflected laser becomes big, and dimensional energy distribution is more scattered, accordingly even when still there is part light
Into the intraocular of doctor, compared to the situation for being not provided with range of atomization, the intensity of this part light will significantly reduce, and only can form one
Doctor, which is observed, influences little low-light level hot spot.
The processing method of range of atomization is as follows：Mould corresponding position is handled with chemical attack or electric spark or blasting method
Surface, make mould that there is larger roughness in the region, so that the corresponding surface on product also forms the thick of range of atomization
Rough surface.
