no. 1 example

[0023] Such as figure 1 As shown, the fully-sealed flexible connector for hysteroscopic surgery of the present invention includes: a trumpet-shaped capsule 9 , a liquid-filled tube 1 , a sleeve 6 , a main sleeve 3 and at least one branch sleeve 4 . The trumpet-shaped bag 9 is made up of at least two liquid-filled rings 7, for example, there are 2-5 liquid-filled rings 7, the inner cavities of the liquid-filled rings 7 communicate with each other, and the sleeve 6 is cylindrical, and one end of it is connected to the liquid-filled ring. 7. The inner edge is annularly airtightly connected. The sleeve 6 is connected to the inner hole of the trumpet-shaped bag 9, and the other end is connected to the trunk sleeve 3 and at least one branch sleeve 4. There can be multiple branch sleeves 4, for example: figure 1 There are two in the middle, the trunk sleeve 3 is installed in the center of the sleeve 6, and the two branch sleeves 4 are respectively installed on both sides of the trunk...

[0028] Such as image 3 As shown, the fully enclosed flexible connector for hysteroscopic surgery in this embodiment and figure 1 The fully enclosed flexible connectors used in hysteroscopic surgery are basically the same, and the similarities will not be described again. The difference is that the trumpet-shaped sac 9 is composed of an upper liquid ring 13, a lower liquid ring 14 and a liquid ring connected to each other. Several connecting pipes 12 are formed, and several connecting pipes 12 connect the circumferences of the upper liquid ring 13 and the lower liquid ring 14, the lower liquid ring 14 is connected with the sleeve 6, and the lower liquid ring 14 is equipped with a liquid filling pipe 1.

[0030] Such as Figure 4 As shown, the fully enclosed flexible connector for hysteroscopic surgery in this embodiment and figure 1The fully enclosed flexible connectors used in hysteroscopic surgery are basically the same, and the similarities will not be repeated. The difference is that the bell-shaped capsule 9 is composed of a bell-mouth barrel 10 and several ribs 11, and the bell-mouth barrel 10 is a bladder filled with liquid, in which there are several ribs 11 connecting adjacent walls of the bladder.

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.
