Problems solved by technology

[0003] The disadvantage of this type of prevention is that patients who have placed an IUD have to take out the device after 3 to 6 months
Moreover, the IUD has no tissue repair function, and may scratch the endometrial wall just after the operation

Embodiment Construction

[0017] The present invention and its advantages will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The stent of the present invention is made of a sheet-like medical-grade biodegradable polymer, preferably a copolymer of polylactic acid-glycolic acid PLGA, which is stamped by a mold such as figure 1 or figure 2 As shown in the sheet, the outer surface of the sheet is sprayed with a water-soluble glycerin layer 5 to form the product of the present invention.

[0019] figure 1 The sheet shown is mainly composed of a supporting part 1 and a clamping part 2 , and the clamping part 2 is connected to the rear end of the supporting part 1 in a rod shape. The supporting part 1 is a symmetrical body with a smooth curve on its outer contour, and its front end is a smooth curve shrinking toward the center. The supporting part 1 is provided with two symmetrically placed holes 6 through which body fluids can pass.

Abstract

The invention relates to a biological support filled in a uterine cavity. The support is a platelet prepared from non-toxic biodegradation polymers, the outer surface of the platelet is coated with a water-solubility glycerol layer, the platelet comprises a supporting part and a clamping part, the profile of the supporting part is a smooth curve, a hole for a body fluid to pass through is arranged on the supporting part, and the clamping part in a rod shape is arranged at the back end of the supporting part. The invention has the advantages that the biological support can be very convenientlyplaced in a uterus without damaging a cervical opening and the intimae of the uterine cavity in the placing process and acquire the expected medicament releasing time, medicaments can automatically degrade after being released and do not need to be taken out, and in the process of degradation, the biological support can repair the intimae of the uterine cavity to accelerate the improvement of an illness state.

Description

technical field [0001] The invention relates to a medical device, in particular to a biological support for uterine cavity packing used in physical therapy for the prevention and treatment of intrauterine adhesion syndrome. Background technique [0002] At present, the prevention of intrauterine adhesions caused by surgical trauma and postoperative infection is mainly to place intrauterine devices at the same time after surgery to prevent adhesions; when infection factors exist, antibiotics are given. [0003] The disadvantage of this kind of prevention is that patients who have placed the IUD have to take out the IUD after 3 to 6 months of placement. Moreover, the IUD has no tissue repair function, and may scratch the endometrial wall just after the operation. Contents of the invention [0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a biological stent for uterine cavity packing that can be easily...
