Vaginal dilator for exposing vagina

Abstract

The invention provides a vaginal dilator for exposing a vagina, and relates to the technical field of medical instruments. The vaginal dilator comprises a dilator body and a pushing cylinder for retracting and feeding the dilator body into a vagina; the dilator comprises a fixing ring, a holding cylinder and a plurality of compressed elastic slender rods connected between the fixing ring and the holding cylinder; the fixing ring is connected with the holding cylinder through a pull rod; the pushing cylinder penetrates through the holding cylinder and then is slidably connected with the fixingring; the middle of each elastic slender rod is fixedly connected with a magnetic attraction piece; an electromagnet device capable of attracting the magnetic attraction pieces is arranged in the pushing cylinder; the magnetic attraction pieces are connected to the pushing cylinder through detachable springs; the elastic slender rods are wrapped with lubricant bags; and one end, close to the elastic slender rods, of the holding cylinder is rotationally connected with an angle ruler ring. The vaginal dilator solves the problem that in the prior art, a vaginal speculum cannot perform comprehensive examination due to the fact that the shielding range of the vaginal dilator on the vaginal inner wall is large.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a vaginal dilator for exposing the vagina. Background technique [0002] The vaginal dilator is used for dilating the vagina, so that the cervix and vaginal tissue are fully exposed to facilitate medical workers to observe and perform medical operations on lesions of the lower reproductive tract. In the past, vaginal lesions were considered a rare disease, and most colposcopy rooms were used for the diagnosis and treatment of cervical lesions. Therefore, the common vaginal dilator is a disposable plastic two-leaf vaginal dilator with adjustable opening size. It is used to dilate the vagina and expose the cervix. However, because the two-leaf vaginal dilator often covers the upper and lower walls of the barrel-shaped vagina during gynecological examination, the examiner has nearly half of the blind spot for observing the vaginal wall. The incidence of vaginal lesions is i...
