Abstract
The utility model relates to an improved fallopian tube recanalization assembly. The improved fallopian tube recanalization assembly comprises a double-cavity balloon catheter and a guide wire, wherein the double-cavity balloon catheter comprises a balloon cavity and a guide wire cavity. The tail section of the guide wire cavity is inserted into or connected with a connection device which is provided with at least two end ports; at least one of the ports is a contrast agent injection end port with a control valve; meanwhile, at least one of the ports is a guide wire inlet end port, when penetrating into the end port, the guide wire can guarantee that little or no contrast agent overflows. The improved fallopian tube recanalization assembly achieves the simultaneous operation of contrast agent injection and guide wire penetrating and saves operation procedures and operation time; meanwhile, the contract agent can lubricate the guide wire to reduce the resistance of the guide wire; the double-cavity balloon catheter can steer accurately to avoid repeated steering under fluoroscopy, thereby effective avoiding the damage of the operation to a patient and reducing the radiation to a doctor and the patient.
Description
Technical field
This utility model relates to a kind of gynaecological and obstetrical instrument, particularly a kind of improved fallopian tube recanalization assembly.
Background technology
Along with social development, the sickness rate of infertility increases year by year, and fallopian tube factor shared ratio in female acyesis is the highest, accounts for 35%.Miscarriage, uterine cavity and pelvic inflammation often cause salpingemphraxis.Therefore become the important method of its treatment as noninvasive fallopian tube Interventional Salpingography.Mainly contain in the market the Gooseneck type integrated tubal re-through device of oviduct dredging suit that U.S. COOK company provides and domestic Nanjing company of Wicresoft.The former siphunculus again is comprised of pig tail catheter head and uterine neck suction cup, and seal wire is difficult to search out bight, palace fallopian tube opening after entering uterine cavity, and seal wire is detected easy damage inner membrane of uterine cavity repeatedly; Although the latter has taked the eccentric balloon technology, but because air bag section and catheter tip distance is fixing, and patient's uterine cavity degree of depth individual variation is larger, therefore in practical operation seal wire to enter the probability of bight, palace fallopian tube opening still less, and head end adopts harder leaded plastic material single hole conical design more easily to increase the weight of the damage of inner membrane of uterine cavity.
Moreover, above-mentioned two kinds of dredging conduit head ends all adopt the single hole design, when being placed in the bight, palace, the conduit head end is unfavorable for that contrast agent enters uterine cavity and observes bight, palace situation, and catheter shaft has all adopted the plastic material that hardness is higher, while causing putting pipe, because of palace body and cervical canal angle problem difficult intubation, even if insert by force the pain degree and the uterine cavity that have also increased the weight of the patient, damage.Because the existence of above-mentioned shortcoming causes operating time greatly to extend, patient and get involved the ionizing radiation that the doctor accepts the long period (often every get involved the dredging art need 1～1.5 hour), and success rate of operation descends.In sum, two kinds of main fallopian tube recanalization apparatus structure complexity in the market, complex operation, it is expensive that (external every cover is about 4000 yuan of left and right, and domestic every dredging pipe also reaches 1000 yuan of left and right), efficiency is lower, is difficult to universal in department of obstetrics and gynecology intervention field.
The inventor has applied for that on January 24th, 2013 name is called a kind of fallopian tube recanalization assembly, the patent of invention that application number is 2013100222816.A kind of fallopian tube recanalization assembly is disclosed, the catheter with double-cavity saccule and the seal wire that comprise balloon cavity and guidewire lumen, the catheter with double-cavity saccule front portion is provided with the deflection sacculus, described catheter with double-cavity saccule top is smooth circular arc, the catheter with double-cavity saccule front end has three holes, is respectively seal wire through hole and symmetrical the first liquid outlet and second liquid outlet of sidepiece on top; The terminal part jag is balloon cavity rear and guidewire lumen rear, and the end of described balloon cavity rear is fixedly connected with check valve, and described seal wire is the straight peen seal wire.The inventor further studies the effect of finding that above-mentioned fallopian tube recanalization assembly injects contrast agent and penetrates seal wire because guidewire lumen has concurrently simultaneously, make catheter tip position when deflection when squeeze into gas to balloon cavity, due to the used time of doing of gas pressure, the contrast agent in tube chamber can reflux, and pollutes; Simultaneously when being dredged art, need to adjust seal wire towards, during current operation in the perspective situation, the doctor relies on experience rotation tube chamber, yet the tube chamber outer wall is little without any sign and lumen diameter, more easily rotates 360 ° of situations that are returned to initial point, more repeatedly adjust, increased the injury of operation to human body, and all there is certain harm in perspective to doctor and patient body.
