Gynecological vaginal speculum

Abstract

The invention relates to the field of medical instruments, in particular to a gynecological vaginal speculum. The gynecological vaginal speculum comprises an upper expanding sheet, a lower expanding sheet and an arch part for connecting a rear end corner of the upper expanding sheet and a rear end corner of the lower expanding sheet; a threading ring is fixed at the inner side of the front end ofthe upper expanding sheet; a threading hole and a threading pipe are arranged on the arch part; the lower expanding sheet is connected with a traction wire; the tail end of the traction wire sequentially penetrates through the threading ring, the threading hole and the threading pipe, wherein the upper expanding sheet and the lower expanding sheet can close to a buckling state when the traction wire is pulled backwards, and the upper expanding sheet and the lower expanding sheet can be reset to an open state after the traction wire is loosened; and the traction wire clamping device for preventing the traction wire from moving forwards is arranged on the traction wire. The gynecological vaginal speculum is simple in structure and low in cost and is extremely suitable for disposable use. When the gynecological vaginal speculum is clinically used, an open operation field can be obtained, and hindrance to diagnosis and treatment operation can be reduced. The expansion force of the gynecological vaginal speculum tends to be balanced and adjustable, so that the gynecological vaginal speculum is good in applicability, is convenient and fast to adjust, saves time and labor, and has a wideclinical application prospect.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable medical vagina dilator. Background technique [0002] Vaginal dilators are commonly used in the routine examination and surgical treatment of gynecological diseases to expand the vagina to obtain the necessary inspection field of view or surgical field. It is one of the more commonly used medical devices in gynecological clinics. The commonly used vaginal dilators are usually composed of an upper dilator, a lower dilator, a handle, and a locking mechanism. The end is used to adjust the opening angle of the upper expansion piece and the lower expansion piece, and the locking mechanism is used to lock the relative position of the upper expansion piece and the lower expansion piece to maintain the desired expansion degree. At present, the commonly used vaginal dilator has a relatively complex structure and is difficult to process. In addition, it is usually made of high-quality medi...

AI Technical Summary

Problems solved by technology

At present, the commonly used vaginal dilator has a relatively complex 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, since both sides of the rear end of the upper dilator and the lower dilator are hinged, the opening at the rear end of the vaginal dilator is a closed ring, which affects the openness of the operative field, and the hinged part often creates certain obstacles to the instrument operation and the doctor's line of sight. Obstacles, affecting the effectiveness and efficiency of diagnosis and treatment
