Disposable active cervical dilator bar

Abstract

The invention relates to a disposable active cervical dilating rod which is a common appliance in contraception operation of obstetrics and gynecology department. Physical dilation and medical softening of cervix are adopted simultaneously, and dilation can be carried out rapidly once the invention is inserted into cervix. The design retains gentle slope type physical dilation from thin to thick, and a dilation section in the hollow part of the rod is provided with a capillary channel communicated with the rod chamber. The chamber is filled with filler which has good water absorption and does not react with medicine, and quantitive anesthetic is injected. A plane is fixed by a stand sealing the rod core. When the invention is used, a stand clasp is moved aside, and pressure is applied to cause medicine to exude uniformly. Then cervical mucosa anesthesia is carried out to soften the cervix, and the physical dilation is carried out rapidly. The invention is suitable for cervical dilation required in operations of obstetrics and gynecology department and family planning department, and has the advantages of rapid speed, good effect, little pain of patient, few complications, few side effects, simple and convenient operation, disposability and reduction of hospital cross infection and disinfection load.
