Problems solved by technology

Although liquid uterine distension is widely used at present, it is mostly used in hysteroscopic pathological examination, but it cannot be applied in abortion
The reasons are as follows: firstly, when the intrauterine cavity is injected with liquid and curettage is performed, the bleeding in the intrauterine cavity is easy to spread and dissolve in the medium

Abstract

The invention relates to a mechanical uterus dilatation device used for assisting in finishing gynecological operations, in particular to visual induced abortion operations, and belongs to the technical field of medical devices. The mechanical uterus dilatation device comprises a front dilatation mouth (1), an outer tube (2), a flexible inner catheter (3) and a handle (4), wherein the outer tube (2) is communicated with the tail part of the front dilatation mouth (1) and is hollow; the flexible inner catheter (3) is positioned inside the outer tube (2); the handle (4) is positioned at the tail part of the flexible inner catheter (3); the part of the outer tube (2) close to the front dilatation mouth (1) is bent for 5-10 degrees; a chute (1-1) is formed inside the front dilatation mouth (1) and is connected with the front part of the outer tube (2) through a rotation pair; and the flexible inner catheter (3) comprises a head (3-2) close to the front dilatation mouth (1). The mechanical uterus dilatation device has the advantages that the mechanical uterus dilatation device is used for minimal invasion and better adapts to the intrauterine environment, the operation complication caused by gas and liquid uterus dilatation is avoided, and a larger observation and operation space is provided for the visual induced abortion operation.

Description

technical field [0001] The invention relates to a surgical instrument, specifically designed for a gynecological surgical instrument, in particular to a uterine expansion device for gynecological abortion and pathological examination of the uterine cavity. Background technique [0002] Uterine dilatation technology is widely used in gynecological surgery and intrauterine examination. Its fundamental function is to expand the closed uterine cavity to form a visual environment and an operating environment. The methods of uterine distension currently used in clinical practice can be divided into two categories: balloon uterine distension and medium uterine distension. [0003] Balloon uterine distension is an early method of uterine distension, which uses a transparent rubber film to cover the front end of the hysteroscope and injects gas or water to inflate the film to expand the uterine cavity. This method is basically not suitable for intrauterine surgery in the early stage...
