Improved expander for anorectal and vaginal examination and operation and manufacturing method of improved expander

Abstract

The invention discloses a manufacturing method of an improved expander for anorectal and vaginal examination and operation. According to the manufacturing method, a T-shaped groove is formed in the middle of a fixed base, blind hole type sliding chutes are symmetrically formed in two sides of the front part of the fixed base, a semi-circular petal I is arranged at the top end of the fixed base, sliding columns are symmetrically arranged on the two sides of the inner surface of a cavity structure of a sliding base, the sliding columns are clamped into the sliding chutes of the fixed base, so that the sliding base can move front and back relative to the fixed base, meanwhile, the sliding base also can rotate around the sliding columns, a semi-circular petal II is arranged at the top end of the sliding base, a rectangular through hole is formed in the tail of the sliding base, and a stop block passes through the rectangular through hole and the T-shaped groove sequentially and is screwed down through a bolt, so that the fixing of the sliding base and the fixed base is realized. The improved expander is simple in structure, is safe and reliable, and is ingenious in design, a suitable field of view and operation space are provided for the anorectal and endovaginal operation, other unnecessary operation measures such as the incision for the anus during the anorectal operation are avoided, and convenient operation and examination environments are provided for doctors.

Description

technical field [0001] The invention discloses a method for making an improved dilator for anorectal vaginal examination and operation, and belongs to the technical field of medical equipment. Background technique [0002] At present, medical dilators are indispensable devices for gynecological examinations and anorectal examinations in various medical institutions. The existing medical anorectal vaginal dilators are generally composed of upper and lower expansion blades, and most of them are parallel or close to parallel in the closed state. , the upper expansion blade and the lower expansion blade are put into the anorectum or vagina when they are closed, and the lever of the handle is used to force the front ends of the upper expansion blade and the lower expansion blade during inspection. Since the locking position of the lever generally has only one stall, Therefore, its brace opening is not necessarily suitable for doctor's examination; at the same time, the force of t...
