Intrauterine adhesions often occur after intrauterine procedures due to endometrial fibrosis and wall adhesions resulting from damage to the basal lamina of the endometrium. Patients often show reduced menstruation or amenorrhea, severe cases even resulting in infertility. Even if pregnant, it is prone to develop bad pregnancy outcomes such as abortion, premature birth, placenta implantation, etc. The body and the mind of the patient bear great pain. Intrauterine adhesion has the characteristic of easy recurrence, especially severe intrauterine adhesion, and postoperative re-adhesion is more likely to occur. At present, surgical treatment, drug treatment and instrument treatment are mainly adopted for the treatment of uterine cavity adhesion, and the instrument treatment mainly comprises the following steps: injecting anti-adhesion gel (such as sodium hyaluronate gel), placing saccule, placing intrauterine device, and placing intrauterine anti-adhesion device.
The intrauterine adhesion preventing device generally adopts a bracket similar to an intrauterine device, a film is arranged in the area range surrounded by the bracket, intrauterine adhesion is prevented by a physical isolation mode, but four problems exist: the support of intrauterine device mainly considers how to fix itself in uterus (supporting function), does not need to consider the shape and uterine cavity to be completely consistent, and the support of any shape cannot be completely matched with the uterus of all individuals due to individual difference, so that the outer side of the support is inevitably provided with a gap; the film is attached to the bracket, so that the bracket is pulled by the film during intrauterine contraction and diastole, and the supporting function of the bracket is limited; the film is pulled and flattened by the bracket in a natural state, but when the bracket in uterus is stressed and deformed, the film can twist and fold; the film is a complete film, has large compression area on the endometrium, is unfavorable for the growth of the endometrium, completely blocks the convection of intrauterine liquid, is unfavorable for the drainage of intrauterine effusion and is easy to cause infection. For this reason ZL201420416287.1 discloses a palace chamber adhesion prevention and cure ware, sets up the convection orifice, avoids the not smooth infection that causes of drainage, but this technical scheme realizes comparatively difficultly, and micropore aperture and area scope are too big, and less aperture 0.1mm, area 1%, the great aperture 5mm, area 40%, aperture are little to be difficult to reach the drainage effect, and the aperture is big to be difficult to play anti-adhesion effect.
