Abstract

This utility model relates to a kind of Salpingography recanalization conduit, belongs to medical apparatus and instruments.This utility model inner catheter is provided with sacculus, in inner catheter, be provided with first passage and second channel, first passage one port is connected with sacculus, another port is connected with syringe, second channel one port is divided into two-way, two-way curved catheter is outwardly-bent formation "eight" shape respectively, and second channel another port is connected with the anti-valve that backflows.This utility model trocar sheath is hollow type pipe, and can move along inner catheter, adopts inner catheter both can carry out Salpingography, also can coordinate seal wire to carry out fallopian tube recanalization treatment simultaneously.Inner catheter one end is "eight" shape port design, make to find bilateral cornua uteri and become simple, Salpingography diagnostic reliability and accuracy are improved, reduce the operation wound that repeatedly intubate is brought, shorten treatment time, localization has been saved cost, and relieve patient ' s burden can also reduce the impact of lonizing radiation on patient and the generation of doctor's health.

Description

Salpingography recanalization conduit

Technical field:

This utility model relates to a kind of Salpingography recanalization conduit, belongs to medical apparatus and instruments.

Background technology:

Infertility is a kind of commonly encountered diseases of the numerous women of child-bearing age, frequently-occurring disease, the infertility that obstruction of fallopian tube causes has accounted for infertility 30% one 50%, Salpingography inspection is the goldstandard of diagnosis obstruction of fallopian tube, the CooK conduit of import, seal wire dredging has become the most effectual way for the treatment of obstruction of fallopian tube, the Guan Jun of admittance again of current clinical practice mostly enters intrauterine head and is flat-head shape, then by stretching into conduit searching cornua uteri in admittance pipe again, its complicated operation, operating time is longer, not only bring larger misery to patient, and bring the radiation of long period to operation doctor, unfavorable to health.

Summary of the invention:

The technical problem that utility model will solve is: provide rational in infrastructure, easy to operate, reduce the operation wound that when uterus is infertile treats, repeatedly intubate is brought, shorten treatment time, alleviate patient suffering, and the low a kind of selective salpingography admittance pipe again of cost.

This utility model solves the technical scheme that its technical problem adopts:

This utility model comprises trocar sheath and inner catheter, inner catheter is provided with sacculus, in inner catheter, be provided with first passage and second channel, described sacculus is connected with a port of first passage, the another port of first passage is connected with syringe, one port of described second channel is divided into the first curved catheter and the second curved catheter two-way, the first curved catheter and the second curved catheter be outwardly-bent formation "eight" shape respectively, the another port of second channel is connected with the anti-valve that backflows, and has the interface that connects liquid injection pipe on the sidewall of second channel.

Further: the another port of first passage is arranged on the tube wall of inner catheter 3.

The beneficial effects of the utility model are: trocar sheath is hollow type pipe, and can move along inner catheter, adopt inner catheter both can carry out Salpingography, also can coordinate seal wire to carry out fallopian tube recanalization treatment simultaneously.Due to the design of conduit one end "eight" shape port, make to find bilateral cornua uteri and become simple, reliability and the accuracy of Salpingography diagnosis are greatly improved, reduce the operation wound that repeatedly intubate is brought, shorten treatment time, localization has been saved cost greatly, relieve patient ' s burden, but also can reduce the impact of lonizing radiation on patient and the generation of doctor's health.

Fig. 1 is front view of the present utility model;

Fig. 2 is this utility model using state figure;

Fig. 3 is the cutaway view of Fig. 2.

Detailed description of the invention:

This utility model is to be made up of trocar sheath 4 and inner catheter 3 two parts, and described trocar sheath 4 adopts stainless steel material to make, and trocar sheath 4 is casement pipe, is enclosed within on inner catheter 3, and can moves along inner catheter 3; In inner catheter 3, be provided with two passages, inner catheter one end is provided with sacculus 2, sacculus 2 is connected with a port of first passage 9, first passage 9 another port 5 are arranged on inner catheter 3 tube walls, and be connected with syringe, one port of described second channel 8 is divided into the first curved catheter 1 and the second curved catheter 10 two-way, the first curved catheter 1 and the second curved catheter 10 outwardly-bent formation "eight" shape respectively, the another port of second channel 8 is connected with the anti-valve 6 that backflows, and has the interface that connects liquid injection pipe 7 on the sidewall of second channel 8.

When use, by selective salpingography again admittance pipe send into uterine cavity through cervix uteri mouth, trocar sheath 4 is retreated, the first curved catheter 1 and the second curved catheter 10 are launched, the first curved catheter 1 after expansion and the opening of the second curved catheter 10 are aimed at respectively two cornua uteris, and expose sacculus 2, be filled with appropriate amount of fluid or air by the another port 5 of first passage 9, make sacculus 2 expand by selective salpingography again admittance pipe be fixed in uterine cavity.

When Salpingography, inject contrast agent by liquid injection pipe 7, can diagnose fallopian tube to have or not and block.

When fallopian tube recanalization, can send into seal wire by the anti-valve 6 that backflows of the another port of second channel 8, enter respectively the first curved catheter 1 and the second curved catheter 10 and get involved dredging treatment.
