Abstract

The invention discloses a disposable balloon catheter for cervical dilation. The disposable balloon catheter comprises a pressurizing assembly and a dilation balloon, the dilation balloon comprises acatheter body connected with the pressurizing assembly, a dilating assembly clamped on the catheter body and a filling head, a medium filling channel is formed in the end, facing the catheter body, ofthe filling head, and a clamping groove is formed in the inner wall of the connecting end, facing the dilating assembly, of the catheter body; the dilating assembly comprises a buckle, a silicone tube sleeved with the buckle and a connecting rod which is sleeved with the silicone tube, a clamping ring is arranged on the outer wall of the connecting rod and clamped into the clamping groove, the end, facing the dilating assembly, of the filling head penetrates through the buckle to extend the tail end of the silicone tube, and an inner cavity of the silicone tube is communicated with the mediumfilling channel. The clamping groove and the clamping ring are clamped, so that the catheter body and the connecting rod are connected more conveniently; gas or liquid sequentially passes through thecatheter body and the medium filling channel and then enters the inner cavity of the silicone tube, the silicone tube expands outwards to dilate the cervix uteri, and therefore the cervix uteri is slowly expanded at a time to a size which ensures smoothness of an operation.

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...
