Disposable cervical dilation balloon catheter

Abstract

The invention provides a disposable cervical dilation balloon catheter, which comprises a pressurizing component and a dilation balloon. The pressurizing component and the dilation balloon are connected with each other. During dilation, a hose component enters vagina along with a connection component, an inflation head and a dilation component under the guide action of a guide wire, gas or liquidis filled into the dilation balloon by the pressurizing component and enters the dilation component through a guide passage, a connection passage and a medium filling passage sequentially, the dilation component expands outwards to realize cervical dilation, and accordingly cervical dilation can be realized slowly in one time to reach a size for guaranteeing surgical success, pains of a patient can be alleviated, injuries of cervical mucosa are reduced, and safety and smoothness in a cervical dilation process are guaranteed. After cervical dilation is completed, the guide wire is pulled out, automatic sealing of a silicon rubber plug is realized under the elastic recovery force of a silicon rubber adaptor and the silicon rubber plug, and the dilation balloon is indwelled in vagina by folding of a silicon rubber extrusion tube.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a disposable cervical dilatation balloon catheter. Background technique [0002] When performing family planning operations, gynecological examinations, or operations on the vaginal uterus and its accessories, the cervical canal must be dilated in order to better meet the needs of the operation. At present, the method of dilating the cervical canal in the prior art is: using metal or plastic uterine dilating rods with different diameters, inserting them into the cervix in order from small to large, pulling them out, and hard dilating the cervix to reach the size of the cervix for surgery. The doctor’s operation is very cumbersome and may cause damage to the cervical mucous membrane; or use certain materials to expand the cervix through the moistening of the cervical mucus to expand the cervical canal. This method is related to the secretion of the cervix, and the dilating...

Problems solved by technology

At present, the method of dilating the cervical canal in the prior art is: using metal or plastic uterine dilating rods with different diameters, inserting them into the cervix in order from small to large, pulling them out, and hard dilating the cervix to reach the size of the cervix for surgery. The doctor’s operation is very cumbersome and may cause damage to the cervical mucous membrane; or use certain materials to expand the cervix through the moistening of the cervical mucus to expand the cervical canal. This method is related to the secretion of the cervix, and the dilating effect is often Not good, it is not conducive to the safe and smooth operation process

In addition, existing methods of dilating the cervical canal with metal or plastic dilators use instruments that cannot be placed in the vagina
