Disposable medical vaginal dilator

Abstract

The invention relates to the field of medical instruments, and particularly discloses a disposable medical vaginal dilator. The disposable medical vaginal dilator comprises an upper expanding piece, alower expanding piece and an arch part for connecting the rear end corners of the upper expanding piece and the lower expanding piece; a threading ring is fixed to the inner side of the front end ofthe upper expanding piece, and a threading hole is formed in the arch part; the lower expanding piece is connected with the front end of a pull wire, and the tail end of the pull wire penetrates through the threading ring and extends to the outside of the arch part through the threading hole, and finally is connected with the arch part; and a plurality of wire hanging teeth are fixed outside the arch part, and when the pull wires are arranged on different wire hanging teeth, the opening states of the upper expanding piece and the lower expanding piece are different. The vaginal dilator is simple in structure, easy to manufacture and low in cost, and is extremely suitable for one-time use; in clinical use, an open surgical field can be obtained, and the interference to clinical diagnosis and treatment operation can be reduced; the dilation strength of the disposable medical vaginal dilator is balanced and adjustable, the applicability is high, the adjustment is convenient and fast, thetime and labor are saved, and the vaginal dilator has a wide application prospect in clinic application.

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
