shape sacculus.Described flexible axle shape sacculus is got bolt conduit 6 and is comprised that a guide channel 8, a waterflood path 9 and expansion get bolt sacculus 10.Described guide channel 8 axially connects flexible axle shape sacculus and gets bolt conduit 6, for the second seal wire 7, pass guiding, the internal diameter that described flexible axle shape sacculus is got the guide channel 8 of bolt conduit 6 is more than or equal to the diameter of the second seal wire 7, the internal diameter that in the present embodiment, flexible axle shape sacculus is got the guide channel 8 of bolt conduit 6 equals the diameter of the second seal wire 7, by the second seal wire 7 being penetrated to flexible axle shape sacculus, get in the guide channel 8 of bolt conduit, the far-end that makes flexible axle shape sacculus get bolt conduit 6 can pass the thrombosis in thromboembolism arteries and be positioned at thrombosis far-end under the guiding of the second seal wire 7, conveniently get bolt operation.Described expansion is got bolt sacculus 10 and is positioned at the far-end that flexible axle shape sacculus is got bolt conduit 6, for taking out the thrombosis of thromboembolism arteries, flexible axle shape sacculus is got the far-end connection expansion of the waterflood path 9 of bolt conduit and is got bolt sacculus 10, in the present embodiment, flexible axle shape sacculus is got sidewall that the far-end of the waterflood path 9 of bolt conduit gets bolt conduit through flexible axle shape sacculus and is got bolt sacculus 10 with expansion and be communicated with, for getting 10 water fillings of bolt sacculus to expansion, making expands to get after bolt sacculus 10 is heaved is close to the arterial vascular inwall of thromboembolism, so only need repeatedly pull out and put in flexible axle shape sacculus gets bolt conduit 6 and just can utilize to expand and get bolt sacculus 10 thrombosis is taken out in thromboembolism arteries, to reach the object of getting bolt, the near-end of waterflood path 9 is used for connecting water filling device (not shown), water filling device can be selected injector for medical purpose etc., the near-end that described flexible axle shape sacculus is got the waterflood path 9 of bolt conduit is provided with the water filling interface 21 of belt switch 21a, the waterflood path 9 that flexible axle shape sacculus is got bolt conduit is connected with water filling device by water filling interface 21, during use, only need open the switch 21a of water filling interface 21, the waterflood path 9 that can get bolt conduit through flexible axle shape sacculus by water filling device is got water filling in bolt sacculus 10 (as diluted iodine water etc.) to expansion, when expansion is got that bolt sacculus 10 is heaved and is close to the arterial vascular inwall of thromboembolism, just can closing switch 21a, stop water filling, thereby get bolt hands art, after getting bolt and having performed the operation, again open switch 21a, just the water that expansion can be got in bolt sacculus 10 is emitted.The external diameter of described flexible axle shape thrombolysis catheter 11 is 4F or 5F, this flexible axle shape thrombolysis catheter 11 is provided with the medicine-injecting cavity 12 of axial perforation flexible axle shape thrombolysis catheter 11, for postoperative, to thromboembolism arteries, inject thrombolytic drug, to dissolve remaining thrombosis, the sidewall of described flexible axle shape thrombolysis catheter 11 far-ends is provided with a plurality of hole 11a that communicate with medicine-injecting cavity 12, in the present embodiment, a plurality of hole 11a that communicate with medicine-injecting cavity 12 are symmetricly set on the both sides sidewall of flexible axle shape thrombolysis catheter far-end, and the hole 11a on each sidewall arranges along the axially spaced-apart of flexible axle shape thrombolysis catheter 11, thrombolytic drug can be maximized the use.
The present invention is work like this:
Referring to Fig. 8, take patient's SMAE as example, patient is flat to crouch after hybridizing on operation table, inguinal region, routine disinfection right side, cut right common femoral artery, and arteries otch upper and lower side is blocked, first under perspective, by intervention, surpass choosing method, the far-end that successively three flexible axle shape sacculus obstruction conduits 1 is provided with to expansion blockage sacculus 5 by the first seal wire 2 is inducted into respectively right renal artery 16 from the incision of right common iliac artery 18, left renal artery 17, the opening part of common iliac artery 19, by the second seal wire 7, flexible axle shape sacculus is got to bolt conduit 6 is provided with the far-end get bolt sacculus 10 that expands and is inducted in superior mesenteric artery 15 from the incision of right common iliac artery 18 simultaneously, and be positioned at thrombosis 20 far-ends through the thrombosis 20 of superior mesenteric artery, then respectively to water filling in the expansion blockage sacculus 5 of three flexible axle shape sacculus obstruction conduits, make the expansion blockage sacculus 5 of three flexible axle shape sacculus obstruction conduits heave rear respectively with right renal artery 16, left renal artery 17, the inwall of common iliac artery 19 is close to, stop up right renal artery 16, left renal artery 17, the blood flow of common iliac artery 19, with the thrombosis 20 that prevents from taking off, drop to right renal artery 16, left renal artery 17, in common iliac artery 19, treat that three flexible axle shape sacculus obstruction conduits 1 are respectively by right renal artery 16, left renal artery 17, after the blood flow of common iliac artery 19 stops up, water filling in bolt sacculus 10 is got in the expansion of getting bolt conduit 6 to flexible axle shape sacculus again, the inwall that is close to superior mesenteric artery 15 after bolt sacculus 10 is heaved is got in the expansion that makes flexible axle shape sacculus get bolt conduit, under perspective, by repeatedly pulling out and put in flexible axle shape sacculus, get bolt conduit 6, utilizing expands gets bolt sacculus 10 incision taking-up from right common iliac artery 18 by thrombosis 20, because the thrombosis 20 of superior mesenteric artery takes out and enters after ventral aorta 14 from this tremulous pulse, the Main Branches of ventral aorta 14, it is right renal artery 16, left renal artery 17, common iliac artery 19 is by interim blocking blood flow, make like this thrombosis 20 enter after ventral aorta 14, can not enter right renal artery 16, left renal artery 17, in common iliac artery 19, thereby thrombosis 20 can be taken out from the right common femoral artery cutting, to complete, get bolt operation.After thrombosis 20 takes out completely, only the water in the expansion blockage sacculus 5 of three flexible axle shape sacculus obstruction conduits need be emitted, can take out flexible axle shape sacculus obstruction conduit 1.What finally the far-end of flexible axle shape thrombolysis catheter 11 is imported to superior mesenteric artery 15 from the incision of right common iliac artery 18 gets bolt place, sew up right common femoral artery, perform the operation complete, thereby being completed, patient gets after bolt operation, can in superior mesenteric artery 15, inject thrombolytic drug by flexible axle shape thrombolysis catheter 11, to dissolve remaining thrombosis.
Above embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; do not departing under the prerequisite that the present invention relates to spirit, the various distortion that those of ordinary skill in the art makes technical scheme of the present invention and improvement all fall in the definite protection domain of claim of the present invention.
