Embodiment 1

[0049] Such as Figure 1a-Figure 1c As shown, according to the first embodiment of the present invention, the bracket 1 of the fully degradable postoperative anti-adhesion device in the uterine cavity is formed by winding a single or single bundle of fully degradable polymer threads 11 repeatedly back and forth, and each thread 11 is formed at the intersection point 12 points can be partially tapped, completely tapped or not tapped. Wherein, the diameter of the wire 11 is 0.5 mm. Wherein, the stent 1 is formed by interspersing braided wires 11 .

[0050] The stent 1 has a top 13 and a bottom 14. In an unconstrained state before implantation as shown, the top 13 has a first diameter, and the bottom 14 has a second diameter, and the first diameter gradually decreases to the second diameter. In this embodiment, the decreasing trend is that the curve decreases, so that the stent 1 presents a pear shape in an unconstrained state before implantation. In a compressed state during ...

Embodiment 2

[0056] Such as Figure 2a-Figure 2c As shown, according to the first embodiment of the present invention, the bracket 2 of the fully degradable postoperative anti-adhesion device in the uterine cavity is formed by winding a single or single bundle of fully degradable polymer threads 21 repeatedly back and forth, and each thread 21 is formed at the intersection point 22 points can be partially connected, completely connected or not connected. Wherein, the diameter of the wire 21 is 1mm. Wherein, the stent 2 is formed by covering the braided wire 21 .

[0057] The stent 2 has a top 23 and a bottom 24. In the unconstrained state before implantation as shown, the top 23 has a first diameter, and the bottom 24 has a second diameter, and the first diameter gradually decreases to the second diameter. In this embodiment, the decreasing trend is linear decreasing, so that the cross section of the stent 2 in an unconstrained state before implantation presents a trapezoidal shape. In ...

Embodiment 3

[0063] Such as Figure 1a-Figure 1c As shown, according to the first embodiment of the present invention, the bracket 1 of the fully degradable postoperative anti-adhesion device in the uterine cavity is formed by winding a single or single bundle of fully degradable polymer threads 11 repeatedly back and forth, and each thread 11 is formed at the intersection point 12 points can be partially tapped, completely tapped or not tapped. Wherein, the diameter of the wire 11 is 0.5mm. Wherein, the stent 1 is formed by interspersing braided wires 11 .

[0064] The stent 1 has a top 13 and a bottom 14. In an unconstrained state before implantation as shown, the top 13 has a first diameter, and the bottom 14 has a second diameter, and the first diameter gradually decreases to the second diameter. In this embodiment, the decreasing trend is that the curve decreases, so that the stent 1 presents a pear shape in an unconstrained state before implantation. In a compressed state during i...

Abstract

The invention relates to an intrauterine postoperative anti-adhesion instrument capable of degrading completely. The intrauterine postoperative anti-adhesion instrument capable of degrading completelycomprises a stent and a drug coating, wherein the stent is formed by a completely degradable polymer, the drug coating is loaded to the outer surface and / or the inner surface of the stent for promoting the repair of the endometrium and preventing adhesion, and the stent has a non-binding state before implantation, a compression state during implantation and an unfolded state after implantation; the stent is of a tubular structure which is unfolded around a central longitudinal axis in a non-binding state before implantation, and the first diameter of the top of the cylindrical structure is larger than the second diameter of the bottom; in a compressed state during implantation, the stent is of a tubular structure which is compressed around the central longitudinal axis, and the diameter of the tubular structure is smaller than that of the second diameter; the stent is a hollow flat sheet in an unfolded state after implantation. According to the intrauterine postoperative anti-adhesioninstrument capable of degrading completely, the intrauterine adhesion caused by wounds after various intrauterine operations can be treated, and the intrauterine postoperative anti-adhesion instrument is particularly suitable for secondary adhesion after the intrauterine adhesion separation operation.

Description

technical field [0001] The invention relates to the isolation, treatment and repair of wounds after uterine cavity surgery, and more particularly relates to a completely degradable postoperative anti-adhesion device in uterine cavity. Background technique [0002] The uterus is an organ that produces menstruation and conceives a fetus. It is located in the center of the pelvic cavity and is a unique organ for women. The size of the uterus is related to age and fertility. A nulliparous person is about 7.5cm long, 5cm wide, and 3cm thick. The uterus can be divided into three parts: the bottom, the body, and the neck. The uterine cavity is an inverted triangle, about 6cm deep, and the upper two corners are "uterine horns", which lead to the fallopian tubes. The narrow lower end is the "isthmus", about 1cm long. [0003] Miscarriage, ring removal, surgery and other uterine operations, as well as infection, will cause various lesions in the uterus area. Uterine disease is one o...
