Fallopian tube interventional therapy deviceTechnical field
The present invention relates to medical apparatus and instruments, be specifically related to a kind of Salpingostomy interventional therapy device, it includes fallopian tubeThe treatment of disease in the double fallopian tube such as bolt, ectopic pregnancy interventional therapy of selectivity radiography, oviduct dredging, fallopian tube.
Background technology
Fallopian tube Interventional Salpingography, i.e. under numeral X ray machine, doctor uses coaxial pipe system by television screen direct-view is lowerSystem, transvaginal, cervix uteri, uterus, cornua uteri insert fallopian tube conduit, carry out selective salpingography, fallopian tube logical and smooth,The operation interventional therapy of disease in the fallopian tube such as oviduct dredging treatment and fallopian tube plunger, ectopic pregnancy, according to oviducalConcrete condition inserts micro-wire through fallopian tube conduit to fallopian tube, micro-wire first inserts fallopian tube mouth, then is inserted by microtubularIn inner catheter, by inner catheter, microtubular is inserted in fallopian tube, then carry out the multiple reduction of fractions to a common denominator from therapeutic process.Either go upState any operation interventional therapy, the interventional therapy device used at present include import coaxial 3F microtubular or 5F inner catheter and0.018 micro-wire, this interventional therapy device there is problems in that over the course for the treatment of one be inner catheter be overall, in order to makeInner catheter front end can form the flexibility being suitable for Uterus wall, and inner catheter uses the plastics of certain degree of hardness to make, due to Uterus wallStretching, extension radian varies with each individual, and inner catheter bending front end flexibility be fixing, operate inner catheter time, for some withThe endometrium that inner catheter leading portion angle misfits can cause damage, brings pain to patient, long and narrow to some cervix uteri especially, viscousWhen even patient narrow, partly malformed uterus carries out fallopian tube interventional therapy, have the most rigid inner catheter front end be not easy intoEnter uterus or fallopian tube, operate microtubular after entrance and endometrium can be caused damage, time serious, be likely to result in the perforation of uterusWith hemorrhage；Although two be existing microtubular bending before g. slice header for rubber-metal positioning head, but under DSA digital X-ray machine, interiorThe catheter positioning time is long, thus adds the X-ray radiation damage to human body；It is to get involved with the fallopian tube of this inner catheter to control againTreatment just can only complete in the hospital of the DSA digital X-ray machine being furnished with costliness, is not suitable with basic hospital fallopian tube under B ultrasonic and gets involvedTreatment.
Summary of the invention
For the deficiency of prior art fallopian tube interventional therapy, the invention provides a kind of by arbitrarily regulation is soft inConduit leading portion flexibility, makes inner catheter guide microtubular to be inserted into fallopian tube internal orifice rapidly and accurately, and patient can be made differentThe fallopian tube intervention device that shape endometrium is the most injury-free.
The technical problem to be solved in the present invention is adopted the technical scheme that: outside described fallopian tube interventional therapy device includesConduit, the inner catheter that can slide in outer catheter and the microtubular that can slide in inner catheter, described inner catheter is by flexible materialThe inner catheter leading portion made and the inner catheter back segment being made up of hard material combine, and described inner catheter leading portion termination is metalPositioning head, extended, the other end outer to metal positioning head in described microtubular one end is connected with tube for transfusion, setting on described inner catheterThere is through wires hole, in described through wires hole, be provided with that one end is fixedly linked with inner catheter leading portion termination, the other end is connected with bobbin winolerDrag wire, rotates bobbin winoler and inner catheter leading portion termination can be made to form flexibility.
In order to make inner catheter leading portion termination can form flexibility to the left and to the right, inner catheter is provided with and is symmetrically distributed inThe through wires hole of microtubular both sides, be respectively arranged with in through wires hole one end be all connected with paragraph header before inner catheter, the other end respectively withBobbin winoler be connected left drag wire and right drag wire, bobbin winoler is rotatable wire spool, wire spool when right rotation, right tractiveLine pulls inner catheter leading portion termination to bend to the right, thus right surface of internal cavity is inserted into right fallopian tube mouth along uterus can to make inner catheter,Wire spool is when anticlockwise, and left drag wire pulls inner catheter leading portion termination to bend to the left, thus inner catheter can be made left inside along uterusSurface, chamber is inserted into left fallopian tube mouth.
Under numeral X ray machine or B ultrasonic, doctor is looked at straight by television screen, pulls drag wire, so that it may make inner catheter leading portion endHead flexibility is inserted into fallopian tube mouth, due to the bending of inner catheter leading portion termination along difform intrauterine cavity surface (face)(angle) degree can people arbitrarily regulate, therefore inner catheter leading portion intron in utero time, damage would not be caused in intrauterine cavity surface；WithTime there is flexibility due to inner catheter leading portion termination, beneficially inner catheter can be inserted into fallopian tube mouth the soonest soon, shortensIntervention time, reduces x-ray and damages human body radiation, decrease the pain of patient.
Described metal positioning head uses the rubber being added with two kinds or above metal dust to make.
Main innovation of the present invention is to be designed to both have flexibility, again by the rigid inner catheter originally with fixed bend tuneCan form flexibility at any angle by the regulation inner catheter front end of drag wire, this innovation solves prior art fallopian tubeGet involved the problem in the presence of logical art, and achieve significant technique effect；Simultaneously also by improving metal positioning head, shortenThe positioning time of inner catheter leading portion, improve accuracy and the fastness of inner catheter location.
Inner catheter leading portion termination of the present invention is to have opacity and the gold developing under B ultrasonic and being made up of metal and rubberBelong to positioning head, and all can realize inner catheter under B ultrasonic machine under numeral X ray machine and the most quickly position, when shortening positioning actionBetween, decrease x-ray and human body is damaged, basic hospital also can be made to carry out fallopian tube Surgery simultaneously；Inner catheter is divided into twoPartly, soft good macromolecular material is used to make by stretching into intrauterine inner catheter leading portion, for ease of operation use, after inner catheterDuan Caiyong has sub-plastic cement (acrylic) material of certain degree of hardness and makes, in order to ensure soft good inner catheter front end can be formed because ofPeople and different flexibility, it is ensured that when inner catheter is inserted into the fallopian tube mouth of different patient, reduce the damage to endometrium, includingThe bobbin winoler that inner catheter front end flexibility can arbitrarily regulate it is provided with on conduit.
The invention have the characteristics that:
1, it is without operating on, it is not necessary to general anesthesia, no pain, safety, effectively；
2, damage little, recover fast, effective, little to the interference of health, protect to the full extent and remain normal structureAnd organ；
3, shortening the inner catheter interventional procedure time, decrease x-ray and damage human body, use microtubular to fix after inserting can simultaneouslyLean on, it is not easy to come off, it is to avoid insertion is repeated several times；
When the fallopian tube internal orifice that inner catheter is inserted into different patient 4, can be made, little to endometrial impairment；
5, expand range, make basic hospital also can carry out fallopian tube Surgery under B ultrasonic.
