Abstract

The invention provides an anti-adhesion cervical dilatation stent. The anti-adhesion cervical dilatation stent comprises a cervix uteri opening limiting assembly, a supporting assembly and a cervical dilatation assembly. The cervix uteri opening limiting assembly is connected to the head end of the supporting assembly, and the cervix uteri expanding assembly wraps the outer side of the support assembly. The cervical dilation assembly comprises an elastic bag body and a dilation ring assembly, the expansion ring assembly is arranged on the support assembly in a sleeving mode and connected with the elastic bag body, and the elastic bag body covers the outer side of the dilation ring assembly in a sealed mode. The cervical dilatation stent can play a role in continuous cervix uteri dilation, hematocele in the uterine cavity can be fully drained after a patient with cervical dysplasia is subjected to a cervix uteri forming operation, and formed cervix uteri is not prone to closing after a period of time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-adhesion cervical dilation stent. Background technique [0002] Clinically, some patients need cervical canal adhesion separation due to cervical canal adhesion, and some patients need cervical plastic surgery due to cervical dysplasia. After the operation is completed, cervical adhesion is often prone to reoccurrence, resulting in unsatisfactory surgical results. The methods used in the past include placing an intrauterine device, relying on the tail wire of the IUD to penetrate the cervical canal to achieve isolation; or placing a small double-lumen urinary catheter. The tail wire of the IUD is too thin, and the isolation effect is not good; the balloon of the double-lumen catheter must be filled with water to be placed in the uterine cavity without falling off, and the placement time is often only a few days. Both methods have a greater impact on the uterine c...
