Abstract
The utility model relates to a uterine cavity packing biological stent adopting a sheet object made of nontoxic polymeride with biodegradability. A water-soluble glycerin layer is arranged on the surface of the sheet object comprising a support part and a clamping part; the contour of the support part is a smooth curve; a hole for body fluid to pass through is formed on the support part; and the rod-shaped clamping part is arranged at the rear end of the support part. The biological stent has the advantages that the stent can be conveniently placed into a uterus without hurting cervix uteri port and uterine cavity endomembrane; anticipatory medicine release time is obtained; the stent can be automatically degraded after medicine release and does not need to be taken out; and during the degradation process, the uterine cavity endomembrane can be repaired, so that recovery is quickened.
Description
Technical field
This utility model relates to medical apparatus and instruments, relates in particular to a kind of biological support filled in uterine cavity of the use in the naturopathy of prevention, treatment intrauterine adhesion syndrome.
Background technology
At present, the prevention of the intrauterine adhesion that causes for operation wound and postoperative infection mainly is a postoperative placement of intrauterine devices simultaneously, prevents adhesion; When having infective agent to exist, give antibiotic.
The defective of this kind prevention is the patient of placement of intrauterine devices, places and must take out birth control apparatus after 3～6 months.And intrauterine device inorganization repair function might also can scratch just postoperative inner membrane of uterine cavity wall.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, and providing a kind of can push in the uterine cavity easily, and does not need biological support filled in uterine cavity that it is taken out in the uterine cavity once more.
Above-mentioned purpose is by realizing with following technical proposals:
The tablet of described support for making with the nontoxic biological degradable polymer, this tablet appearance is provided with the water solublity glycerin layer, described tablet comprises support portion and clamping part, the gabarit of described support portion is a smooth curve, this support portion is provided with the hole that allows body fluid see through, and clamping part is the shaft-like rear end that places the support portion.
Described support further design is that the front end gabarit of support portion is the smooth curve that shrinks to the center.
Described support further design is, the support portion is provided with two symmetric described holes, this hole extands rearward to the support portion outer rim, make rear end, the support portion disengagement in the outside, described hole and the free end that is connected to become of clamping part, clamping part extends to the anterior of support portion forward and is connected with the support portion is anterior.
Described support further design is that the used Biodegradable polymer of support is the copolymer of polylactic acid-glycolic guanidine-acetic acid.
The copolymer p LGA of this utility model support medical grade biological degradation polyalcohol---polylactic acid-glycolic guanidine-acetic acid makes.The copolymer p LGA of polylactic acid-glycolic guanidine-acetic acid is nontoxic Biodegradable polymer.This polymer is good biocompatibility in vivo, and catabolite lactic acid and hydroxyacetic acid can participate in the metabolism of human body, finally forms carbon dioxide and water is excreted.PLGA has obtained drugs approved by FDA listing (pharmaceutic adjuvant, bio-medical material).This product has following characteristics: 1) thermoplasticity is good, high strength, and molecular weight is controlled, and scalable depolymerization speed makes it to grow to degraded in 3 years most in a few weeks or months thus; 2) degree of crystallinity is controlled, thus the resolvability of telomerized polymer; 3) change the copolymer molar ratio, obtain the pharmaceutical release time of expection.This utility model support can be degraded in 4～5 weeks, did not need to allow patient take out again; The PLGA porous support can be repaired inner membrane of uterine cavity in degradation process, quickens the course of disease and takes a turn for the better.
This utility model support appearance is coated with water solublity glycerol, forms the water solublity glycerin layer.Glycerol has good lubrication after hydrophilic, being convenient to support can be pushed smoothly, by the cervix uteri mouth, and can not scratch cervix uteri mouth and inner membrane of uterine cavity.The support portion of this utility model support is provided with porous, and body fluid sees through orifice flow and goes out, and can not assemble on support, produces harmful effect
Description of drawings
Fig. 1 is the structural representation of this utility model support.
Fig. 2 is the cutaway view of the A-A position of support shown in Figure 1.
Among the figure, 1 support portion, 2 clamping parts, 3 support portion front ends, 4 support portion gabarits, 5 water solublity glycerin layer, 6 holes.
The specific embodiment
Below in conjunction with drawings and Examples this utility model and advantage thereof are described further.
Support of the present utility model is with flaky medical grade biological degradation polyalcohol---poly-(lactic-co-glycolic acid) copolymer (PLGA) is made, and the support of making is thing in the form of sheets.See also Fig. 1, Fig. 2, the appearance of this tablet is provided with water solublity glycerin layer 5, and this tablet mainly is made up of support portion 1 and clamping part 2 two parts.Clamping part 2 is connected the rear end of support portion 1.
During use, this support per vaginam reaches the cervix uteri mouth and places intrauterine, because the front end of support is contraction-like, be convenient to the insertion of support, and the support portion gabarit of support is slick curve, and support can be placed smoothly, and can not scratch cervix uteri mouth and inner membrane of uterine cavity in put procedure.Support does not need to take out again, and in degradation process, inner membrane of uterine cavity is repaired placing intrauterine degraded automatically during 4～5 weeks, quickens the course of disease and takes a turn for the better.
