Embodiment 1

[0042] (Example 1) see figure 1

[0043] In this embodiment, the selective tubal liquid passer includes a long natural latex tube, i.e. liquid passer body 1, the top of which is in the shape of a smooth arc, with an opening hole in the center of the arc shape, which is the outlet of the liquid medicine. Hole 2, the center of the long natural latex tube is a circular cavity, the length of which runs through the entire length of the natural latex tube. Natural latex tube, the cavity is the air bag cavity 5; the periphery of the latex tube is bonded with a natural latex film, which is 1 cm away from the top of the liquid-passing device tube body 1, that is, the lowest point of the liquid outlet hole 2 There is a section of natural latex film with a length of 1.5 cm that is not bonded on the latex tube and is separated from the latex tube. The natural latex film section of this separation section is the air bag part 3, and the natural latex film thickness of the air bag part 3 is...

Embodiment 2

[0044] (Example 2) see figure 2

[0045] In this embodiment, the selective tubal liquid passer includes a long natural latex tube, i.e. liquid passer body 1, the top of which is in the shape of a smooth arc, with an opening hole in the center of the arc shape, which is the outlet of the liquid medicine. Hole 2, the center of the long natural latex tube is a circular cavity, the length of which runs through the entire length of the natural latex tube. Natural latex tube, the cavity is the air bag cavity 5, and the periphery of the latex tube is bonded with a natural latex film, which is 1 cm away from the top of the pipe body 1 of the liquid-passing device, that is, the lowest point of the liquid outlet hole 2 There is a section of natural latex film with a length of 1.5 cm that is not bonded on the latex tube and is separated from the latex tube. The natural latex film section of this separation section is the air bag part 3, and the natural latex film thickness of the air b...

Embodiment 3

[0046] (Example 3) see image 3

[0047] In this embodiment, the selective tubal liquid passer includes a liquid passer tube body 1, which is composed of two independent natural latex tubes and a natural latex film wrapped outside the two latex tubes, wherein the independent latex tube has a diameter At 1.27 mm, it is much larger than another latex tube. The latex tube with a diameter of 1.27 mm is the drug infusion cavity 4, and the other is the air bag cavity 5. The length of the airbag chamber 5 is shorter than that of the infusion chamber 4. There is only the medicine infusion chamber 4 cavity at the top of the liquid passage tube body 1. The top of the liquid passage tube body 1 is smooth and arc-shaped, and there is a center of the arc-shaped center. The opening hole, which is the liquid medicine outlet hole 2, is covered with a section of natural latex airbag membrane 10 at a distance of 0.5 to 1.5 centimeters from the top of the pipe body of the liquid passer, with a...

Abstract

The invention relates to a selective hydrotubation device, which comprises a hollow hydrotubation device tube body, wherein the top end of the hydrotubation device tube body is provided with a medicine liquid outlet hole; the middle upper end of the hydrotubation device tube body is provided with an airbag part; a medicine conveying cavity and an air bag cavity are formed inside the hydrotubation device tube body; the tail end of the hydrotubation device tube body is provided with an air bag air inlet opening and a medicine liquid inlet opening; a flexible metal layer is arranged inside or outside the medicine conveying cavity or arranged at the common outside of the medicine conveying cavity and the air bag cavity; or the air bag part consists of two air bags symmetrically distributed on the main body of the hydrotubation device tube body. The flexible metal layer or double-air-bag design is used, so that the problem of insufficient rotating torque force transmission of a natural latex tube in the prior art can be effectively solved; the goal of precisely regulating the angle of a latex tube or rotating the latex tube in manual operation in surgery operation can be achieved; and meanwhile, the position of a catheter under x rays can be efficiently marked by the flexible metal layer or a metal marking element, so that the surgery operation difficulty is obviously reduced. The selective hydrotubation device has the advantages that the surgery time can be effectively shortened; the trauma of a patient is reduced; and the radiation receiving quantity of medical care personnel and the patient in the surgery operation can be reduced.

Description

technical field [0001] The invention relates to a gynecological interventional operation instrument, in particular to a fallopian tube fluid passer. Background technique [0002] According to statistics, in recent years, the incidence of female infertility has increased year by year, and tubal disease is an important cause of female infertility, accounting for 35%. water etc. Among them, non-invasive tubal interventional recanalization has become an important method for the treatment of tubal obstruction. [0003] The inventor applied for an invention patent named a fallopian tube recanalization component with the application number 2013100222816 on January 24, 2013. A fallopian tube recanalization assembly is disclosed, which includes a double-lumen balloon catheter and a guide wire. There is a deflecting balloon at the front of the double-lumen balloon catheter. The first liquid outlet hole and the second liquid outlet hole are symmetrically distributed on the side; the...
