Description

Conduit is perfused in fallopian tubal

Technical field:

The utility model relates to a kind of fallopian tubals, and conduit is perfused, it belongs to medical aid, especially a kind of to be used for woman The auxiliary instrument of section's interventional therapy.

Background technique:

Salpingemphraxis is the major reason for leading to female acyesis, accounts for about the 50% of cause of infertility.Fallopian tubal Interventional recanalization Art (FTR) is the main means of Current therapeutic obstructive oviduct lesion, has apparent logical effect, but current art again immediately Used in seal wire, the problem of being based on its structure, its mechanically decoupled effect can damage endosalpinx in art, cause local inner membrance Oedema, tissue inflammatory reparation: vasopermeability increases, and a large amount of cell infiltrations, cellulose exudation cause gluing again for fallopian tubal Connect and the serious post-operative problems such as occlusion.The major measure of clinical prevention FTR postoperative fallopian tube adhesion again at present is primary in art Property inject resist blocking and that medical fluid and postoperative plurimenorrhea uterine cavity into fallopian tubal and lead to liquid art, but effect is not satisfactory.Mainly due to The impaired interstitial tubal of inner membrance and isthmus muscle layer is thicker, lumen is narrower in art, postoperative muscle shrinks, fallopian tubal itself wriggling Etc. reasons, make injection resist blocking and that medical fluid be difficult to retain here (target spot), it is difficult to reach resist blocking and that effect；In addition, fallopian tubal Oedema can be generated after inner membrance is impaired, myxedema can be such that originally narrow lumen occludes again herein, while inflammatory oozes out, again Adhesion.

Summary of the invention:

The purpose of this utility model is to provide a kind of structure is simple, easy to use, the postoperative fallopian tubal that can be trapped in has Effect avoids the fallopian tubal of adhesion again and occlusion that conduit is perfused.

The utility model is achieved in that

A kind of fallopian tubal perfusion conduit, it is characterised in that its closed conduit of the other end including an one end open, The conduit is provided with multiple side openings on the tube wall of closed end portion；The open end includes two open ports: One irrigation ports and a sacculus port；A sacculus is provided in the middle part of the conduit.

The filling volume of the sacculus is 3-6ml.

The length of the conduit is 50-70cm.

The center of the sacculus is to closed end distance are as follows: the cm of 7-9.

The irrigation ports are the open end of conduit, and a brasnch conduct is being arranged at irrigation ports and is connecing a ball Capsule port.

The irrigation ports and sacculus port are arranged in the open end of conduit in 120 degree of angles.

The utility model completely avoids preventing FTR postoperative fallopian tube in the prior art that adhesion and occlusive method are deposited again The drawbacks of, the inner membrance that not only supporting role of tube body avoids postoperative edema contacts with each other, adhesion, moreover, Continuous Perfusion and The advantages of conduit side opening, in turn ensures the duration that resist blocking and that drug acts on mucous membrane.The utility model structure is simple, and operation makes With conveniently, securely and reliably, can be popularized in clinical large-scale popularization.

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model

Fig. 2 is the utility model usage state diagram

Fig. 3 is the structural schematic diagram of the utility model embodiment 2

Specific embodiment:

Below with reference to Fig. 1, Fig. 2 and Fig. 3, the utility model is further detailed:

Embodiment 1, as shown in Figures 1 and 2:

In the present embodiment, the utility model includes an one end open and the closed conduit 1 of the other end, the conduit 1 length can also be fabricated to the different size for meeting the 50-70cm of different patient requests.

It in order to realize the purpose of this utility model, can both be trapped in fallopian tubal, and can also complete to infuse in fallopian tubal Required drug is penetrated, multiple side openings 5, multiple side opening energy are provided on tube wall of the conduit 1 close to closed end portion Guarantee mucosal contact of the medical fluid after side opening flows out sufficiently with scorching change, oedema.Open end described in the utility model includes two Open port a: irrigation ports 3 and a sacculus port 2.It is trapped in the utility model its conduit in postoperative fallopian tube Supporting role be avoided that the mucous membrane of postoperative edema contact with each other, adhesion；Meanwhile transcatheter irrigation ports 3 be periodically perfused again gram Resist blocking and that medical fluid in the prior art has been taken to be not easy the shortcomings that this section retains, and the catheter perfusion of the utility model facilitate it is easy Row, therefore progress can be repeated several times.

The middle part of the conduit 1 is provided with a sacculus 4.It, can be according to demand by institute when processing the utility model The filling volume for the sacculus 4 stated is designed as 3-6ml, and the sacculus of different size specification is made, to meet the use need of specific patient It asks.

Similarly, the center of the sacculus 4 is to closed end 6 apart from the different size that also may be designed to 7-9cm.

From sacculus port injection sterile water make sacculus in uterine cavity fill can fixed catheter, avoid shifting, fall off.

In the present embodiment, the irrigation ports 3 are the open end of conduit 1, and one is being arranged at irrigation ports 3 Brasnch conduct 21 simultaneously connects a sacculus port 2.

Working principle of the utility model is:

As shown in Figure 2,6 Via vagina 8 of the closed end of the utility model, uterus are sent into fallopian tubal 10, such sacculus 4 It will remain in uterine cavity, the open end of conduit 1 has then stayed in vitro.Injecting sterile water from sacculus port 2 makes sacculus 4 in uterine cavity It is interior full, fixed catheter；Resist blocking and that medical fluid is injected from irrigation ports 3, such resist blocking and that medical fluid will be flowed out from multiple side openings 5, Into in fallopian tubal 10, and it is detained.The utility model fundamentally prevents occluding again for FTR postoperative fallopian tube, improves at a specified future date multiple Passband further increases pregnancy rate, to provide a kind of more scientific effective treatment for vast Infertility caused by fallopian tube obstruction patient Method and approach have a vast market foreground and good development trend.

Embodiment 2,

It is as shown in Figure 3:

In the present embodiment, the irrigation ports 3 and sacculus port 2 are arranged in the open end of conduit 1 in 120 degree of angles.

The other parts of the present embodiment are identical with embodiment 1.
