Description
Technical field
The present invention relates to the aseptic vaginal dilator of the disposable use of a kind of tunnel type, belong to technical field of medical instruments.
Background technology
At present, disposable vagina expander is commonly used in clinical gynecologial examination, current vaginal dilator is a very thin duck bill clip, doctor opens whole folder after being placed on patient's vagina, then close inspection with inspecting lamp or finger or instrument deallocation, in the time finding diseased region, in surgical procedure process, in vagina cavity, can produce smog, existing expander is because structural design is reasonable not, smog is difficult to timely eliminating, affect the diagnosis visual field, doctor can only operate with feel or experience, the diagnostic procedure time is longer, bring great misery to patient, for the disease that needs visual diagnostic, can cause judgement inaccurate, easily cause operation to occur unexpected, in addition, the cell fragment that operation smoke is existed by the particle shape of 95% steam and 5% forms, the existence of particle makes operation smoke produce serious harm to health, it is dizzy that medical personnel feel sometimes, headache, feel sick and wait malaise symptoms.
Also occurred in the market the vaginal dilator of internal illumination light source, it has taking dry cell as power supply the deficiency that is unfavorable for sterilization, and dry cell has the potential safety hazard of blast in patient body. in addition, also there is following deficiency in the vaginal dilator of prior art: expands up and down the adjusting poor controllability between leaf, inconvenience when use, on, after lower expansion leaf opens, the both sides up and down of patient's vaginal canal wall can well be strutted, but there is the situation of coming together in the chamber wall of the left and right sides, disturb the diagnosis visual field, and cannot avoid smog in cavity to assemble, and it is unreasonable to expand up and down between leaf structural design, when use, reliability is poor, easily cause unexpected injury, on, the size of lower expansion leaf is long, easily block uterine neck mouth, and its operating surface width is inadequate, restriction robotic surgery or postoperative stitching.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art, provide the disposable use of a kind of tunnel type aseptic vaginal dilator.
The technical solution adopted for the present invention to solve the technical problems is:
The aseptic vaginal dilator of the disposable use of tunnel type, comprise expansion leaf, lower expansion leaf and push rod, described push rod top is provided with the governor motion upper expansion leaf being regulated when operating, also comprise arc light-guiding pillar and the light source of being located at lower expansion leaf, the bright dipping end of described light source and arc light-guiding pillar butt, described upper expansion leaf is provided with the smoke discharging structure for getting rid of smog in vagina cavity, described smoke discharging structure is made up of tube connector and smoke evacuation groove, smoke evacuation groove both sides are provided with slide rail, upper expansion leaf is provided with the chute of coupling, by coordinating of slide rail and chute, smoke discharging structure and upper expansion leaf removably connect, between smoke evacuation groove and upper expansion leaf, form the smoke extraction chamber passing through for smog,
Also comprise auxiliary expanding mechanism; described auxiliary expanding mechanism is made up of the first expansion part and the second expansion part; first and second expansion part is by enlarged portion, limiting section and department of assembly's composition; first and second expansion part removably connects by the cooperation between department of assembly, is realized the gathering of enlarged portion or is opened by the cooperation between limiting section.
The vaginal dilator of prior art is provided with smoke exhaust pipe, be connected in expansion leaf, be communicated with medical vacuum Negative pressure machine, attract to get rid of the smog producing in operation in vagina cavity, the flow of medical vacuum Negative pressure machine can meet clinical demand conventionally, but because the structural design of smoke exhaust pipe is reasonable not, little for the passage of smog circulation between its connecting portion and smoke evacuation portion, the eliminating of restriction smog, cause smoke discharging effect undesirable, although the flow matches of medical vacuum Negative pressure machine is higher, the two flow is inconsistent, and the service efficiency of medical vacuum Negative pressure machine is not high. Structural design of the present invention, what between tube connector and smoke evacuation groove, formation was larger supplies smog circulation passage, the coupling that the two flow can be fabulous, exhaust smoke level is large, and smoke discharging effect is good.
After upper and lower expansion leaf opens, the both sides up and down of patient's vaginal canal wall can well be strutted, auxiliary expanding mechanism also can well strut the chamber wall of the left and right sides simultaneously, and diagnosis broad view is conducive to the diffusion of smog in cavity simultaneously.
Preferably, described smoke evacuation groove side is also provided with some smoking ports, and described smoking port is located at respectively top and the middle part of smoke evacuation groove, and described chute top and smoke evacuation groove top are also provided with the locking mechanism cooperatively interacting, smoke evacuation groove inserts after chute, is further locked by locking mechanism. Several smoking ports are set, and from the smoke evacuation of diverse location omnibearing stereo, smoke exhaust efficiency is higher, better effects if, and the design of locking mechanism avoids smoke exhaust mechanism and upper expansion leaf to come off, and when use, reliability is high.
Preferably, between described lower expansion leaf and push rod, be provided with location structure, for improving under nature and being subject to the stability between External Force Acting lower expansion leaf and push rod.
Preferably, described lower expansion leaf and push rod include Handheld Division and department of assembly, described location structure is made up of locating slot and locating piece, described locating slot is positioned at two inner sides, lower expansion leaf department of assembly and arranges along its length, described locating piece is positioned at two outsides, push rod department of assembly and arranges along its length, and described lower expansion leaf and push rod are by the cooperation location of locating slot and locating piece.
Preferably, described governor motion is by adjusting knob and forming with the adjusting screw(rod) of connector, and upper expansion leaf is provided with regulating tank, and described adjusting knob and adjusting screw(rod) are spirally connected, and adjusting screw(rod) passes regulating tank and removably connects by connector and push rod. Between upper and lower expansion leaf of the present invention, adopt adjusting knob and adjusting screw(rod) to realize the accurate adjusting of relative position, expand up and down adjusting controllability between leaf good, after adjusting, doctor can rise out hand and do other operation, very easy to use.
