Disposable medical vaginal dilator

Abstract

The invention relates to the field of medical instruments, and specifically discloses a disposable medical vaginal dilator. The disposable medical vaginal dilator comprises an upper dilating wing, a lower dilating wing and a bent bow part used for connecting corners of the rear ends of the upper dilating wing and the lower dilating wing, wherein a screw sleeve is fixedly arranged outside the bentbow part; a screw rod is arranged in the screw sleeve; a threading ring is fixedly arranged at the inner side of the front end of the upper dilating wing; a threading hole is arranged on the bent bowpart; the inner side of the front end of the lower dilating wing is connected with the front end of a pull wire; the tail end of the pull wire penetrates through the threading ring, passes through thethreading hole and is connected with the front end of the screw rod; and the opening state of the upper dilating wing and the lower dilating wing can be adjusted by rotating the screw rod through thepull wire. The disposable medical vaginal dilator provided by the invention is simple in structure, easy to manufacture, low in cost and extremely applicable to disposable use; when the disposable medical vaginal dilator is in clinical use, an open surgical field can be obtained, and hindrance to clinical diagnosis and treatment operation can be reduced; the dilating force of the disposable medical vaginal dilator tends to be balanced and adjustable; and the disposable medical vaginal dilator is good in applicability, convenient and fast to adjust, time-saving and labor-saving, and has wide application prospect in clinic.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical dilator suitable for one-time use. Background technique [0002] Vaginal dilator, also known as vaginal dilator, is often used in routine examination and surgical treatment of gynecological diseases, and it is one of the more commonly used medical devices in gynecology to expand the vagina to obtain a better inspection field of view or surgical field. Commonly used vaginal dilators are usually composed of upper expansion wings, lower expansion wings, handles, and locking mechanisms. 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, the commonly used vaginal dilator has a relatively complicated structure and is difficult to process. In addition, it is usually m...

AI Technical Summary

Problems solved by technology

At present, the 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. Using it as a disposable medical device will greatly increase the cost of diagnosis and treatment of diseases. At the same time, Disposable after use also causes serious waste of data

In addition, because the rear ends 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
