Abstract
The invention relates to a diethylstilbestrol-containing vaginal stent. The diethylstilbestrol-containing vaginal stent comprises silicone rubber and diethylstilbestrol in a weight ratio of 20:(5-8). The diethylstilbestrol-containing vaginal stent has the advantages that by the diethylstilbestrol-containing vaginal stent, contracture rate of artificial vaginas is decreased greatly; the vaginal stent with estrogen slow-release capability is prepared by combination of the silicone rubber and the diethylstilbestrol, so that treatments in the two aspects of vaginal stent treatment and estrogen treatment are unified effectively; therefore, the diethylstilbestrol-containing vaginal stent with the slow-release function has great potential in future clinical application.
Description
Technical field
The present invention relates to a kind of vaginal stent, specifically, is the vaginal stent that contains female phenol about a kind of.
Background technology
The congenital absence of vagina patient is mostly Rokitansky-Kuster-Hauser syndrome (RKH syndrome), is the undergrown result of embryo's bilateral in period gyneduct, and karyotype is 46XX.Congenital absence of vagina patient's treatment has operative treatment and non-operative treatment.Operative treatment comprises vulvovaginoplasty (Williams method), make dibbling pico farad (McIndol method), peritoneum is for vagina method (Rothman method), Sigmoid Colon vagina method (Pratl method), amniotic membrane is rebuild vagina etc. for vagina method and novel biomaterial, and the application of vaginal stent is the very important ring of vaginoplasty post processing.Postoperatively need to place vaginal stent March to half a year, prevent the contracture of artificial vagina.For vaginal vestibule section mucosa good springiness, the table shallow depression person of existence is arranged, can adopt Frank method vagina top to press non-operative treatment.Frank proposed pole compression method non-operative treatment congenital absence of vagina in 1938, adopt the vaginal vestibule section of the pole aligning locking of different-diameter, pressed along normal vagina direction of principal axis top, with dilating urethra rectum gap, finally formed artificial tract.
Chinese patent application CN101352360A discloses a kind of soft bearing band with side opening reconstruction vaginal mold, comprises a body, and this body is provided with several apertures, and an end of body is the Duckbill type cecum, and another end is opening.Chinese patent application CN202078425U discloses the modified form vaginal stent, comprises cylindrical main part, and the front end of described main part is one-body molded has a taper section, the rear end of described main part to offer axial and finger-hole finger size coupling.
But, about can either greatly reducing the contracture rate of artificial vagina, can discharge again estrogenic vaginal stent and yet there are no report.
Summary of the invention
The objective of the invention is for deficiency of the prior art, a kind of contracture rate that can either greatly reduce artificial vagina is provided, can discharge estrogenic vaginal stent again.
One purpose more of the present invention is that a kind of new purposes of vaginal stent is provided.
For achieving the above object, the technical scheme that the present invention takes is: a kind of vaginal stent that contains female phenol, by silicone rubber, female phenol, formed, described silicone rubber, female phenol weight ratio are 20:(5-8).
Described silicone rubber, female phenol weight ratio are 4:1.
For realizing above-mentioned second purpose, the technical scheme that the present invention takes is: the application of vaginal stent in the slow-release medicine of the artificial vagina of preparation treatment.
The invention has the advantages that: contain the contracture rate that estrogenic vaginal stent reduces artificial vagina greatly.The present invention, by silastic material is combined with estrogen, prepares the vaginal stent with estrogen slow-release capability, thereby the treatment of the treatment of vaginal stent and these two aspects of estrin treatment is united effectively.Therefore, this vaginal stent with slow-release function has very large potentiality in clinical practice afterwards.

Embodiment 7
By embodiment
6The laboratory animal be successfully established is after 1 week of rest, more capable vagina anaplasty.12 Chinese miniature pig groupings after the vagina anaplasty are grouped as follows:
Group 1: 4 Chinese miniature pigs after the vagina anaplasty (group 1-1 pig, group 1-2 pig, group 1-3 pig, group 1-4 pig).
Group 2: after the vagina anaplasty, the vaginal stent that embodiment 5 is obtained is positioned over (group 2-1 pig, group 2-2 pig, group 2-3 pig, pig group 2-4 pig) in cave, artificial vagina chamber.
Group 3: after the vagina anaplasty, the vaginal stent that embodiment 1 is obtained is positioned over (group 3-1 pig, group 3-2 pig, group 3-3 pig, group 3-4 pig) in cave, artificial vagina chamber.
Vagina ultrastructure by pig after the above-mentioned vagina anaplasty of electron microscopic observation, the results are shown in Table 1
Table 1: vagina anaplasty each pig vagina contracture situation (each pig vagina contracture area accounts for the percentage ratio of artificial vagina area) after two weeks
| ? | No. 1 pig | No. 2 pigs | No. 3 pigs | No. 4 pigs |
| Group 1 | 50% | 55% | 52% | 50% |
| Group 2 | 12% | 10% | 11% | 13% |
| Group 3 | 5% | 7% | 4% | 3% |
After vaginoplasty, do not place vaginal stent, the contracture rate of artificial vagina is very high; After vaginoplasty, place vaginal stent, can reduce the contracture rate of artificial vagina; Contain the contracture rate that estrogenic vaginal stent reduces artificial vagina greatly.
The present invention, by silastic material is combined with estrogen, prepares the vaginal stent with estrogen slow-release capability, thereby the treatment of the treatment of vaginal stent and these two aspects of estrin treatment is united effectively.Therefore, this vaginal stent with slow-release function has very large potentiality in clinical practice afterwards.
