Abstract
The utility model relates to a uterine cervical dilator which comprises a dilatation body, wherein the outer contour of the dilatation comprises two to five groups of alternative cones and cylinders from front to back, in each group, the cones are positioned at the front end, operating rods are arranged on two sides of the rear end of the dilatation body, a through hole is arranged in the middle of the dilatation body which is connected with the operating rod through screw threads, and the dilatation body and the operating rod are made of stainless steel, medical plastics or medical resin. The uterine cervical dilator has the prominent advantages that the uterine cervical dilator is simple in structure and convenient in use, the outer contour of the dilatation comprises two to five groups of alternative cones and cylinders from front to back and the cones are positioned at the front end in each group, uterine cervixes can be slowly opened up at a time, thus trouble of using a plurality of dilators is avoided, time and labor are saved, and pains of patients are reduced; the through hole is arranged in the middle of the dilatation body, and after the uterine cervixes are opened up, instruments can be stretched into the uterine cervixes from the through hole to carry out operation, thereby effectively lightening weight of the dilator, bringing more convenience for doctors to operate, and relieving sufferings of patients.
