Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Embodiment
As shown in Figure 1, a kind of disposable uterine-expanding rod is disclosed in the present embodiment, can by disposable for cervix uteri expansion palace to guaranteeing to perform the operation the size of carrying out smoothly after using, comprise barred body 2 and be formed in barred body 2 end, and and between the end of barred body 2, be configured with the uterine-expanding head 4 of an angle, trachea 14 is provided with in described barred body 2, the chamber groove 8 be communicated with the air flue in described trachea 14 is provided with in described uterine-expanding head 4, pore 10 is provided with in described uterine-expanding head 4, described pore 10 is communicated with the inside of chamber groove 8, the outside of described uterine-expanding head 4 is also arranged with a closed air bag 12, trachea 14 stretches out air inlet pipe 14 and the negative pressure bleeder port 16 that one end that barred body 2 extends laterally is provided with gas circuit interlocking-type, the end of described air inlet pipe 14 is provided with inflating ball 18.
Based on the said structure of uterine-expanding rod, when it used expansion palace to use, first negative pressure bleeder port 16 is connected negative pressure equipment, gas in closed air bag 12 is all discharged, after gas emptying by uterine-expanding head 4 end intron in utero, the inflating ball of manual operation simultaneously 18 in the process inserted, by air inlet pipe 14, trachea 14, chamber groove 8, pore 10 is inflated in closed air bag 12, closed air bag 12 gos deep into below in the drive of uterine-expanding head 4, limit is inflated, swollen palace (or expanding palace) is carried out to cervix uteri, until stop inflation when the deep degree of depth and swollen palace to cervix uteri mouth guarantee the size that abortion carries out smoothly, complete the operation of disposable expansion palace, expand after palace is terminated and negative pressure bleeder port 16 is connected negative pressure equipment, after all being discharged by the gas in closed air bag 12, extract barred body 2 and uterine-expanding head 4.Consider to insert and extract intrauterine to alleviate by the pain of operation receiveing person, air bag 12 of the present utility model and barred body 2 preferably adopt medical propylene fat-butadiene-styrene (ABS) resin material with excellent tough slip and rigidity to make; Consider that insertion and grabbing when extracting pinch sure effect, this utility model is preferably provided with anti-slip veins 20 in one end away from connection uterine-expanding head 4 of barred body 2; Consideration can check the degree of depth that uterine-expanding head 4 inserts intuitively, preferably on barred body 2, is provided with scale mark 22, avoids deeply inserting the additional injury caused by operator.
Consider the pain further alleviating insertion, air bag 12 of the present utility model is inflated its airbag wall rear and is had conical structure, and it reduces to the cone footpath of its other end gradually from the one end be connected with barred body.
As further improvement of the utility model, the angle α that both described barred body 2 and uterine-expanding head 4 are formed in junction is 10-12 °, further, described uterine-expanding head 4 is connected with the end transition of barred body 2 by first, second circular arc R 1, R2, that is uterine-expanding head 4 is made to be formed in the end of barred body 2 by first, second circular arc R 1, R2, the angle of the uterine-expanding rod made and human body cervix uteri adapts, and is conducive to the smoothness of improvement operation and alleviates the misery of operation receiveing person and avoid injuring uterine cavity and/or cervix uteri.
Therefore, disposable uterine-expanding rod of the present utility model, the uterine-expanding head 4 of single chamber airbag design stretches into after in uterine cavity, by in air bag 12 slowly insufflation gas uterine-expanding head 4 is increased gradually, meeting disposable expansion palace to guaranteeing to perform the operation the size of carrying out smoothly according to the actual needs in operation process by control aeration quantity and aeration speed, reaching the pain alleviating patient, the object reducing Post-operative syndrome incidence rate.
