Its principle and using method are:
Embodiment 1:(is example with left and right sides carotid artery and left subclavian artery)
Select three bifurcated artery shunt tubes before using, the interim tremulous pulse shunt tube of through the three-way valve place entire bracket original position being windowed in aseptic area earlier pours into that with heparin-saline the air in the pipeline is discharged and the pipeline heparinization.At first under B ultrasonic guiding with the vascular puncture syringe needle to patient's head to inserting left and right sides carotid artery, when seeing the arterial blood ejection, with guiding wire in the puncture needle head inserts arteries, guiding wire withdraws from piercing needle from the seal wire rear end after entering tremulous pulse more fully, with blade seal wire is entered the skin place and stab an osculum (being convenient to the insertion of sleeve pipe and sleeving core), the puncture casing that will be inserted with sleeving core again inserts tremulous pulse from the seal wire rear end, sleeving core is harder slightly than sleeve pipe, in the process of inserting, can play supporting sleeve and strut the effect of blood vessel, behind the complete intravasation of sleeve pipe, again sleeving core is withdrawed from arteries fully together with seal wire, blood namely flows into shunt tube through sleeve pipe, after sleeve pipe inserts successfully, available stitching thread is fixed at retainer ring place and the skin closure of sleeve pipe head, carry out the left radial artery puncture according to arteriopalmus then, with fixedly three branches of shunt tube that puncture with quadrat method, and observe each minute puncture casing whether respectively in left and right sides carotid artery and left radial artery through the tee T blood-letting, after determining that three branch's puncture casing are in arterial lumen, using with quadrat method with the puncture of main puncture casing and be fixed in the left femoral artery, turn of tidal stream is carried out in open each threeway.Finish the window turn of tidal stream operation of interim tremulous pulse shunt tube of support original position.This moment, aortic stents can cover right brachiocephalic trunk, left common carotid artery, left subclavian artery simultaneously.Window for next step support original position and to make the blocking-up head and prepare to blood flow.
Embodiment 2:(is example with celiac trunk, superior mesenteric artery, left and right sides renal artery)
Select four bifurcated artery shunt tubes before using, in aseptic area, through threeway the entire bracket original position interim tremulous pulse shunt tube of windowing is poured into that with heparin-saline the air in the pipeline is discharged and the pipeline heparinization earlier.Open the abdominal cavity under the general anesthesia, celiac trunk, superior mesenteric artery, left and right renal artery simply dissociate respectively, with the method for embodiment 1 four branch's puncture casing being punctured respectively is fixed on celiac trunk, superior mesenteric artery, left and right renal artery, finishes celiac trunk, superior mesenteric artery, the arteriorenal turn of tidal stream in the left and right sides.This moment, the ventral aorta support just can cover celiac trunk, superior mesenteric artery, left and right renal artery fully, windowed for next step support original position and did the preparation of blocking-up visceral bloodflow.
By above-mentioned two embodiment as can be known, before covering some important arteries, manage interim approach through circulation of the present utility model earlier target organ is carried out blood supply, then in the regular hour by the overlay film frame that covers these important blood vessels is windowed, recover original blood flow, cancel interim blood supply approach at last again.The overlay film frame that will make that so can success such as is applied near aortic arch and the visceral vessel at the pathological changes of privileged sites, thereby avoids major operation.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment this utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
