Abstract
The utility model provides an intrauterine device for preventing a uterine cavity from being adhered again, which is provided with a uterine-shaped ring, and is characterized in that a flexible biological film is coated on the outer side of the uterine-shaped ring, and the uterine-shaped ring can be completely or incompletely coated by the flexible biological film. The intrauterine device for preventing the uterine cavity from being adhered again can effectively prevent side walls of the uterine cavity and uterine corner areas from being adhered again, further can prevent a middle position in a uterine inner portion from being adhered again in a certain extent, further can prevent a uterine cavity mucous membrane with a harder surface from producing friction, damage or inflammation and inducing other diseases and the like during the uterine contracting process, and is simple to make, low in cost and convenient to use.
Description
Technical field
This utility model relates to a kind of gynecilogical operation medical apparatus and instruments, specifically a kind of again intrauterine device of adhesion of uterine cavity that prevents.
Background technology
Intrauterine adhesion is owing to form the pathological phenomenon of adhesion after the endometrium damaged, can cause Hypomenorrhea, amenorrhea, miscarriage, premature labor, infertile etc.For the treatment of intrauterine adhesion, generally adopt first hysteroscope operation to separate uterine cavity, postoperative is placement of intrauterine devices in uterine cavity, plays buffer action, prevents again adhesion of postoperative, and the n of high dose oral estrogen several months, promotes the endometrium growth.Used birth control apparatus mostly is common birth control apparatus at present, such as O type, T-shaped and uterine cavity shaped de-vice, but the isolation effect of these common birth control apparatus is poor, again adhesion incidence rate of postoperative is high, in addition, the heavy dose of estrogen side effect of Long-term Oral is large, such as liver function infringement, water retention etc., and Long-term Oral medicine patient compliance is poor, thereby affects therapeutic effect.
Summary of the invention
The purpose of this utility model is intended to improve the weak point of prior art, provide a kind of isolation effect good prevent the again intrauterine device of adhesion of uterine cavity.
The technical solution of the utility model is: a kind of again intrauterine device of adhesion of uterine cavity that prevents, and it has uterus shape contraceptive ring, and characteristics are to be coated with the flexible biological thin film in the outside of uterus shape contraceptive ring.
Described flexible biological film coated uterus shape contraceptive ring has two kinds of forms, and a kind of is the outside that is coated on uterus shape contraceptive ring fully, and another kind is the outside that not exclusively is coated on uterus shape contraceptive ring, and is coated on the two sides of uterus shape contraceptive ring, and leaves draining hole at the middle part of uterus shape contraceptive ring.
Compared with the prior art this utility model has following advantage:
1, the uterus shape contraceptive ring birth control apparatus behind the employing flexible biological film coated can not only effectively prevent the again adhesion of sidewall and the palace angular zone of uterine cavity, and can also prevent to a certain extent the again adhesion of inner middle part, uterus;
2, owing to adopted flexible biological film coated uterus shape contraceptive ring, the surface of birth control apparatus is very smooth, can avoid the tenderer uterine cavity mucosa of effects on surface to produce friction, impaired or inflammation, bring out Other diseases etc. in metryperkinesis;
3, the incomplete clad structure of the middle opening of the technical program can also be conducive to the convection current of liquid in the uterine cavity, avoids the infection that causes because of inadequate drainage;
4, the technical program has adopted the coating film structure, for the inboard structure that connects thin film of uterus shape contraceptive ring, makes simplyr with respect to existing, and cost is cheaper.
Below in conjunction with drawings and Examples this utility model is done at length and to be explained.
Description of drawings
Fig. 1-a kind of structural representation of the present utility model;
Fig. 2-another kind of structural representation of the present utility model.
The explanation of accompanying drawing drawing:
1 uterus shape contraceptive ring, 2 flexible biological thin film, 3 draining holes.
The specific embodiment
Embodiment 1, referring to Fig. 1, uterus shape contraceptive ring 1 is substantially the same with existing uterus shape contraceptive ring structure, make elasticity uterus shape contraceptive ring shape by the rustless steel taenidium, flexible biological thin film 2 can adopt to have good flexible high molecular slow-release material (such as silicone rubber, polyurethane, ethylene-vinyl acetate copolymer (EVA) etc.) is made, and with flexible biological thin film 2 uterus shape contraceptive ring 1 is coated fully.Because flexible biological thin film 2 has good pliability, therefore can move with uterus shape contraceptive ring 1 co-contraction, be considered as integrative-structure.
Above-mentioned technique genus prior art commonly used of carrying out overlay film at uterus shape contraceptive ring.
In addition, in order to strengthen therapeutic effect, in uterus shape contraceptive ring 1, also can place copper, medicine for treatment thing etc.
Flexible biological thin film 2 can be made by single membrane material, also can add antibiotics, hemostasis class medicine, antibacterials and contraception class medicine etc. in film.Its dosing method has two kinds, and a kind of is after making flexible membrane, directly applies various medicines at the flexible membrane outer surface; Another kind is can be with high molecular slow-release material and the medicament mixed of masking, then with mixing material masking again.In order to control the release of intrauterine device medicine, flexible biological thin film 2 also can be made into the pore film.
Using method
After hysteroscope operation separates uterine cavity, this birth control apparatus is placed in the uterine cavity, the uterus shape contraceptive ring that coats thickness can increase intrauterine isolation area greatly, prevents again adhesion.If adopt the birth control apparatus that draining hole is arranged, material in the drain uterine cavity is avoided hematocele or hydrops in the uterine cavity better.
