The specific embodiment
Below in conjunction with accompanying drawing this utility model is elaborated.
Extremely shown in Figure 5 such as Fig. 1, the molten broken bolt conduit of the eccentric sacculus of ilium deep femoral vein thrombosis beading, described conduit is the integral type conduit, comprise double channel catheter 3, be located at double channel catheter 3 one ends sacculus interface 1 and Y-valve interface 2, be located at the eccentric sacculus end 4 of beading on the double channel catheter 3 one end conductor housings 31 and thrombolysis catheter end 5, and seal wire 6; Described double channel catheter 3 is formed by two separate conduits fusions of function, cylindrical, wherein two conduits are semicylinder, respectively account for half tube chamber, one of them is as the foley's tube 32 of the eccentric sacculus end 4 of beading, is used for dilating sacculus, and seals at the conductor housing 31 terminal 311 that is being communicated with foley's tube 32, another is as the common conduit 33 of seal wire 6 and injection thrombolytic drug, and its port 312 at conductor housing 31 is opening; Described sacculus interface 1 is made by polythene material, and an end is communicated with foley's tube 32, and other end Bonding pressure pump 7 is by atmospheric pressure expansion of balloon catheter 32; Described Y-valve interface 2 is made by polythene material, is communicated with common conduit 33, is used for connecting Y-valve 8, makes Y-valve 8 as the medicine-pouring port of seal wire 6 entrances and thrombolytic drug; Described seal wire 6 is guiding wire, runs through whole common conduit 33.The eccentric sacculus end 4 of described beading is worked out by nylon and latex, and its balloon diameter has the effect of cutting thrombosis between the 5-20 millimeter, and promotes thrombosis to be pushed movement, and length of balloon is between 10-20 centimetre.
Described thrombolysis catheter end 5 conduits become the crack shape, and the length in crack is 1 centimetre, and are wide 1 millimeter, the quantity in crack and position can be used flexibly, be distributed in the 10-20 cm range of conductor housing 31, crack ceasma direction is conducive to medicine from the direction area contact thrombosis of maximum greater than 180 degree.
Described double channel catheter 3 is made by PEBAX or PU-polyurethane, and tube chamber is made through tube extruding machine and PTFE hydrophilic coating, and described double channel catheter 3 length are 1.2 meters or 1.5 meters, and to satisfy the needs of different puncture paths, the pipe diameter is between 5-8F.Described seal wire 6 is the .035 seal wire.
The eccentric sacculus end 4 of described beading and thrombolysis catheter end 5 both be combined on the conplane conduit.
The eccentric sacculus end of described beading 4 sacculus are beading, and easily machinery is passed, and pushes broken bolt.
The molten broken bolt conduit of the eccentric sacculus of this utility model ilium deep femoral vein thrombosis beading is the thrombus treatment conduit that is integrated for the eccentric broken bolt of sacculus of special beading and conduit thrombolytic, and it can reach simultaneously the purpose to the broken bolt of thrombosis sacculus and conduit contact thrombolysis in the therapeutic process of thrombosis.The design of the eccentric sacculus end 4 of beading can be played the effect of cutting thrombosis in the broken bolt process of thrombosis, by the purpose that moves and balloon expandable can reach broken bolt repeatedly.In addition, in the process of broken bolt, inject urokinase by the thrombolysis catheter pressurization, can increase the solute effect of broken thrombosis, thereby reach the purpose for the treatment of thrombosis.Because foley's tube 32 and common conduit 33 have reduced and have changed the loaded down with trivial details of conduit for integral type designs, and have also reduced simultaneously because the expense of multiple instrumentation.
Wherein the sacculus end of foley's tube 32 can be designed to different length, between beading different intervals can be arranged, the needs during with convenient different thrombus treatment.The tube chamber of common conduit 33 is in use as the passage of seal wire, injection can be used as again the administration channel of thrombolytic drug in the situation that keeps seal wire, its caliber is set as and can passes through smoothly .035 seal wire 6, but the size of tube head take just by seal wire 6 as standard, can be good at confined bed tube head 31 during with assurance injection thrombolytic drug, thrombolytic drug is discharged by the side opening of common conduit 33.The side opening of common conduit 33 can be arranged on the different lengths such as catheter proximal end 10cm or 20cm, and the needs crack ceasma direction when satisfying the different length thrombus treatment is conducive to medicine from the direction area contact thrombosis of maximum greater than 180 degree.Conductor housing 31 ends are the port of export of seal wire 6, are pyramid type, go deep into thrombosis inside to make things convenient for conduit.Foley's tube 32 endcappeds wherein, air-tightness when using with the assurance sacculus, common conduit 33 openings are the seal wire outlet, size is just to satisfy the .035 seal wire by being as the criterion, so that sealing tube head when the injection thrombolytic drug, guarantee the pressure in the thrombolysis catheter, to satisfy thrombolytic drug by the crack spray discharge, improve thrombolytic effect.
The molten broken bolt conduit using method of the eccentric sacculus of ilium deep femoral vein thrombosis beading may further comprise the steps:
The first step by Y-valve interface 2 access Y-valves 8, is then inserted .035 seal wire 6 through the Y-valve mouth, and seal wire 6 by the thrombosis section, is then inserted the molten broken bolt conduit of thrombolysis catheter end 5 through seal wire 6, is placed in the thrombosis section;
Second step, radiography confirm that sacculus is positioned at after the thrombosis, by the eccentric sacculus of sacculus interface 1 expansion beading eccentric sacculus end 4 beadings, to reach the purpose of chopping thrombosis;
The 3rd step, take out flat sacculus, in the situation that keeps seal wire 6, inject thrombolytic drug through Y-valve interface 2, to reach the purpose of thrombolytic, dilating sacculus continues broken bolt again simultaneously, also can inject thrombolytic drug on the basis of balloon expandable, so that the dissolving mural thrombus;
The 4th goes on foot, and constantly regulates the position of foley's tube 32, makes the thrombosis of different azimuth reach cracked and dissolving;
The 5th step, use and finish the rear conduit of releasing, finish associated treatment.
The first step in step, but anticoagulant is injected in the conduit pulse of described thrombolysis catheter end 5, promotes thromboembolism.
In the 3rd step in step, broken bolt be combined with thrombolytic that also the capable of regulating direction is to strengthen molten broken bolt effect, and when pushing mobile thrombosis, thrombolysis catheter end 5 conduits are greater than the 180 pulse thrombolytic drugs of spending, multi-direction maximum area contact lysis thrombosis.
The above only is preferred implementation of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes this utility model description and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
