Medical vaginal dilator

Abstract

The invention relates to the field of medical equipment, and specifically discloses a medical vaginal dilator. The medical vaginal dilator includes an upper expansion wing, a lower expansion wing, anda curved part for connecting two rear end corner parts of the upper expansion wing and the lower expansion wing; a threading ring is fixed on the inner side of the front end of the upper expansion wing, and the curved part is provided with a threading hole; the inner side of the front end of the lower expansion wing is fixedly connected with the front end of a pulling line; the tail end of the pulling line passes through the threading ring to extend to the outside of the curved part through the threading hole, and is finally connected with a line twisting device; and the line twisting deviceis artificially driven to wind and unwind the pulling line, so that the expansion degree of the medical vaginal dilator is adjusted. The medical vaginal dilator is simple in structure, easy to prepare, low in costs, and extremely suitable for one-time use; the medical vaginal dilator can obtain an open surgical field during clinical use, and can reduce the hindrance to clinical diagnosis and treatment operation; and the expansion force of the medical vaginal dilator tends to be balanced and adjustable, so that the medical vaginal dilator has good applicability, is convenient and quick to adjust, saves time and effort, and has broad clinical application prospects.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical vagina dilator for gynecological clinical use. Background technique [0002] Vaginal dilators are often used in the routine examination and surgical treatment of gynecological diseases to expand the vagina to obtain a better inspection field of view or surgical field. It is one of the more commonly used medical devices in gynecology. Currently commonly used vaginal dilators are usually composed of an upper expansion wing, a lower expansion wing, a handle, and a locking mechanism. The end is used to adjust the opening angle of the upper expansion wing and the lower expansion wing, and the locking mechanism is used to lock the relative position of the upper expansion wing and the lower expansion wing to maintain the desired expansion degree. At present, this commonly used vaginal dilator has a relatively complicated structure and is difficult to process. In addition, it is usually mad...

AI Technical Summary

Problems solved by technology

At present, this commonly used vaginal dilator has a relatively complicated structure and is difficult to process. In addition, it is usually made of high-quality medical plastic with high strength, and the production cost is relatively high. The use of it as a disposable medical device greatly increases the cost of diagnosis and treatment of gynecological diseases; at the same time , Disposable after use also caused a serious waste of data

In addition, since both sides of the rear end of the upper and lower expansion wings are hinged, the opening at the rear end of the vaginal dilator is closed loop, which affects the openness of the surgical field, and the hinged part often hinders the operation of the instrument and the doctor's line of sight. , affecting the effectiveness and efficiency of diagnosis and treatment
