Uterine cavity expansion tri-Lobe balloon catheter

Abstract

The invention relates to a uterine cavity expansion tri-Lobe balloon catheter. The uterine cavity expansion tri-Lobe balloon catheter comprises a catheter body, a tri-Lobe balloon is installed on a head portion of the catheter body, the tail portion of the catheter body is respectively connected with an air inflation tube and a wire guiding catheter, the tri-Lobe balloon consists of three air inflation bags which are evenly distributed around the same position of the catheter body serving as a center, the three air inflation bags are expanded towards three directions after inflated by the air inflation tube, a guiding wire penetrates the wire guiding catheter, and when the tri-Lobe balloon on the head portion of the catheter body reaches a part to be treated, the guiding wire is pulled out. By means of the uterine cavity expansion tri-Lobe balloon catheter, a symptom of intrauterine adhesion can be effectively treated, and the tri-Lobe balloon is expanded towards three directions to form a large space to expand inner walls of the intrauterine adhesion part, so that the symptom of intrauterine adhesion can be thoroughly treated, and meanwhile, the effect of hemostasis by compression in the uterine cavity can be achieved.

Description

technical field [0001] The invention belongs to the technical field of uterine cavity expansion, in particular to a three-leaf balloon catheter for uterine cavity expansion. Background technique [0002] Under physiological conditions, the front and rear walls of the normal uterine cavity are in contact with each other, and there will be no adhesion even when the endometrium is stripped during menstruation, because the integrity and function of the basal layer of the endometrium are normal. Once the endometrium is stimulated and damaged due to inflammation, trauma, drug corrosion or foreign matter, etc., it will cause damage to the endometrial basal layer, changing the regular growth and shedding of the endometrium in the normal menstrual cycle, which can lead to uterine stroma. Fibrinogen exudates and deposits, causing adhesions on the anterior and posterior walls of the uterine cavity. [0003] At present, a balloon catheter is used to enter the uterine cavity through the...

AI Technical Summary

Problems solved by technology

[0003] At present, a balloon catheter is used to enter the uterine cavity through the cervix to separate the adhesions. However, because the existing balloon catheter is a bilobed balloon with a small expansion surface, the separation effect on moderate and severe adhesions is poor, and it causes great pain to the patient. Therefore, it is necessary to exclude the symptoms of intrauterine adhesions, expand the inner wall, and reduce the pain of the patient. So far, there is no suitable balloon catheter
