Fully-closed flexible connector for hysteroscope operation

Abstract

The invention discloses a fully-closed flexible connector for hysteroscope operation. The fully-closed flexible connector comprises a horn-mouth-shaped bag, a liquid injection pipe, a sleeve, a main sleeve and at least one branch sleeve. One end of the sleeve is connected with an inner hole of the horn-mouth-shaped bag, and the other end of the sleeve is connected with the main sleeve and the branch sleeves. The ends of the main sleeve and the branch sleeves are each provided with a check valve, and the main sleeve and the branch sleeves are provided with three-way valves. The liquid injection pipe is arranged on the portion, close to the sleeve, of the horn-mouth-shaped bag and penetrates through and extends out of the sleeve. The liquid injection pipe is provided with a liquid injection valve. Liquid is injected into the horn-mouth-shaped bag through the liquid injection valve and the liquid injection pipe so that a supporting frame can be formed with the horn-mouth-shaped bag. The connector can not easily slide out of cervix uteri and can not occupy excessively large space in uterine cavity, so the wideness and smoothness of a pipeline in a ring are ensured; a user puts in a hysteroscope for observation through the main sleeve and puts in surgical instruments through the branch sleeves, interference is small, and surgical operation is easy.

Description

technical field [0001] The invention relates to an auxiliary device for hysteroscopic surgery, in particular to a fully-sealed flexible connector for hysteroscopic surgery.

Problems solved by technology

[0002] In traditional hysteroscopic surgery, a hard outer sheath is placed into the uterine cavity through the cervical canal, thereby expanding the cervical canal outward. , electric cutting ring, water injection pipe, etc. go in and out parallel to the lumen of the outer sheath, that is, all kinds of surgical instruments use the long cylindrical pipe in the outer sheath as the fulcrum, limited by the hard outer sheath, the observation mirror and operating instruments only To be able to go straight, the long handle of the surgical instrument must also be linear, because the surgical instrument comes from one direction in the uterine cavity, that is, after the hysteroscope through the outer sheath fixes the field of view, the operation through the same outer sheath The operating instruments can only advance and retreat, but cannot change in the left and right directions at will, so the range of movement of the surgical instruments is limited, which affects the cooperative operation

[0003] The uterine distension fluid used in traditional hysteroscopy is easy to leak from the cervical canal. At present, the balloon is used to seal it. However, due to the small volume of the uterine cavity, although the balloon is too large, it can seal the leakage, but it occupies too much of the uterine cavity and affects the observation. and operation, but the balloon is too small and easy to slip from the cervical canal when the uterine inflation pressure increases
