Endometrial repair device

Abstract

An endometrial repair device comprises a cannula. The inside of the cannula is provided with a diaphragm body which axially and spirally curls around the cannula. The two sides of the cannula are provided with axial through slots providing space for the unfolding of the diaphragm body, and the axial through slots extend to the upper end of the cannula and are open at the end faces in order to guide the diaphragm body out of the casing. The lower end of the cannula is connected with a driving tube for driving the diaphragm body to rotate. When the diaphragm body unfolds, the diaphragm body is shaped as a spatial curved surface body with a big top and a small bottom so as to adapt to the shape of the uterus cavity. The diaphragm body comprises a skeleton layer in the middle and a diaphragm layer coating the upper and lower sides of the skeleton layer. The inside of the diaphragm body is equipped with a rotating shaft along the axial direction of the cannula, and the lower end of the rotating shaft is connected with the upper end of the driving tube. A tail wire is laid axially inside the rotating shaft, and the free end of the tail wire extends into the driving tube. The endometrial repair device can separate the front and back walls of uterine from each other to prevent intrauterine adhesion, promote orderly proliferation of damaged tissues and reduce the sequela of endometrial mechanical injury. The endometrial repair device is economic and safe, and has good patient compliance.

Description

technical field

[0001] The invention relates to a device for repairing endometrium. Background technique

[0002] In recent years, with the opening up of society and the promotion and application of abortion technology, the number of abortions and the number of repeated abortions have increased year by year, and the incidence of postoperative intrauterine adhesions has also increased accordingly. Intrauterine adhesion (IUA), also known as Asherman syndrome, is manifested as hypomenorrhea or amenorrhea, periodic abdominal pain, early and mid-gestational miscarriage, recurrent or habitual miscarriage, delayed miscarriage, ectopic pregnancy, premature delivery, and intrauterine death And abnormal placental implantation, etc., seriously affect women's reproductive ability and physical and mental health.

[0003] The normal endometrium has the ability of periodic exfoliation and repair, and the integrity and continuity of the basal layer may play an important role similar to the...
