Description

Disposable variable-angle type hydrotubation device

Technical field

This utility model relates to a kind of improvement of hydrotubation device, and specifically a kind of disposable variable-angle type hydrotubation device is applicable to the fallopian tube recanalization art that causes the women of infertility because of salpingemphraxis.

Background technology

Salpingemphraxis is one of major reason that causes infertility, is a kind of commonly encountered disease, frequently-occurring disease, also is a kind of disease of comparatively refractory simultaneously.Therapeutic Method commonly used at present is to adopt hydrotubation or lead to art again with interventional radiology method row, employed hydrotubation apparatus is mainly made of stainless steel tube, the front end slight curvature, liquid outlet is established in the end, its rear end is provided with inlet opening and pressure tap, in practical operation, pressure tester seldom uses clinically, is difficult to promote in grass-roots unit especially; Fluid-passing device rear end volume is big, can influence concrete operations; In addition, the weight of stainless steel tube own is bigger, is difficult for perception to oviducal pressure; Reuse, easily cause cross infection; In addition, the little bending angle of front end is fixed, and can not become and directly to the opening part injection of fallopian tube at angular intrauterine, has bigger blindness because of the people.

Summary of the invention

The purpose of this utility model is to provide a kind of operation not only simple in structure, easy, can disposablely uses, avoid cross infection, and little bending angle of front end is adjustable, adapt to the needs of fallopian tube easily, make conduit can arrive the disposable variable-angle type hydrotubation device of angular intrauterine fallopian tube opening part fast and accurately in the different openings direction of angular intrauterine.

For reaching above purpose, the technical scheme that this utility model adopted is: this disposable variable-angle type hydrotubation device, by outer catheter, inner catheter and seal wire constitute, inner catheter is inserted in the tube chamber of outer catheter, seal wire is inserted in the inner catheter, it is characterized in that being provided with " V " shape recess at leading section 24-26mm place from outer catheter, a side of " V " shape recess between the outside of the inboard of catheter wall and inner conduit wall is provided with the angle adjustment drawing silk outside, draw ring is established in the outer end of angle adjustment drawing silk, the inner is fixed on outer catheter " V " the shape recess upper wall, make the end bent of outer catheter by pulling angle adjustment drawing silk, the size of its angle of bend, can decide in the difference of angular intrauterine opening direction according to patient's fallopian tube, thereby in making, the sensing of outer catheter head end can coincide at the angular intrauterine opening direction with fallopian tube fast, shorten the operating time, reduce the doctor, patient's roentgen radiation x amount, bonding upper film gas cell on the wall of the outer catheter of the rear side of " V " shape recess, inflation inlet is established in the gas tube outer end, and insert in the thin film gas cell the inner of gas tube.This utility model is also implemented by following measure: described angle adjustment drawing silk is provided with the angular adjustment scale mark, its angle of regulation range α is the 0-20 degree, the also sheathed hand-held guide pipe of outer end of conduit outside, hand-held guide pipe is the tubular pipe, can slide along outer catheter, outer wall is provided with anti-skidding stricture of vagina, and the front end of inner catheter is a taper, and liquid outlet is established at the tip.When using this utility model, can adopt blind inserting, also can under X line perspective, insert, blind when slotting when adopting, allow the patient by the conventional pendulum mass of uterine cavity Salpingography position earlier, sterilization, drape, expose cervix uteri, finding out on the basis of uterus position, regulate the outer catheter angle of bend that adapts with uterus position and form, through cervix uteri outer catheter is inserted uterine cavity, rely on hand-held guide pipe, the outer catheter head is inserted angular intrauterine, and fix with hands, the inner catheter that will have seal wire then inserts in the outer catheter, sends to angular intrauterine fallopian tube opening part, and the 1-2mm of matter portion between inserting, through inner catheter vasopressing injection contrast agent in fallopian tube, to increase the fallopian tube fluid pressure,, show that the adhesion release embolus is discharged in the fallopian tube if contrast agent enters pelvic cavity, fallopian tube is logical again, if still obstructed, seal wire can be pulled and pushed at obstructive position and make its multiple leading to, also can be through directly injectable drug treatment in fallopian tube of inner catheter.If under roentgen radiation x, insert, can rely on hand-held guide pipe that outer catheter is inserted earlier, and in time spur the angle adjustment drawing silk, make the outer catheter end towards the angular intrauterine bending, and inserting the fallopian tube opening part, the reuse hands is fixed, and then inserts the inner catheter that has lead, and the 1-2mm of matter portion between inserting, below operation is with blind slotting identical.

The beneficial effects of the utility model are: simple in structure, easy to operate, use flexibly, safe and reliable, can blindly insert, and also can under X line perspective, insert the success rate height.
