Polyamide and barium sulfate material are made, and 100 outer wall of tube body is additionally provided with developing ring 400, can develop under X-ray, convenient
Staff carries out the position for grasping this closure pipe when plugging operations in time.Pass through the end of the first cavity 120 and the second cavity 130
Physiological saline of the injection containing contrast agent into the first empty pocket 200 and the second empty pocket 300 is held, the liquid that can develop is logical from first respectively
The first empty pocket 200 and the second empty pocket 300 are injected in hole 121 and the second through-hole 131, utilizes the first empty pocket 200 and the second empty pocket 300
Successive fluid injection expansion reaches the space for occupying defect, so that blood be blocked to flow into the right heart through ventricular septal defect from left ventricle
Room, and it is small on organ dysfunction influence, it creates conditions for subsequent surgical intervention or Occlusion therapy.After second empty pocket, 300 fluid injection
Expansion molding, the smallest one end in cross section can be close to defect location, the better effect of blocking blood flow circulation.Room after myocardial infarction
Septal defect may be gradually expanded in a short time, the adjustable section expanded after two empty pockets of this closure pipe are full, to adapt to
Different degrees of septal defect, and it is easy to operate, and wound is small.
As one of optional embodiment, the end of first cavity 120 and the second cavity 130 is equipped with can
The device for casting 700 of disassembly.The device for casting 700 includes pedestal 710, and the pedestal 710 sets that there are two the notes that are spaced apart
800 card slot of emitter can be connected with syringe 800 in each described 800 card slot of syringe, and in each syringe
The side of 800 card slots is also equipped with rotatable closing piece 720, for blocking the syringe 810 of syringe 800, each injection
The head end of 800 syringe 810 of device is connected with liquid injection pipe 830, and respectively with first cavity 120 and second cavity 130
Clamping, is perfused with the physiological saline containing contrast agent in the syringe 800.After each described 800 card slot of syringe
Portion is additionally provided with the opposite pushing block 730 moved back and forth, and each pushing block 730 is equipped with piston rod bayonet.For
It avoids the first empty pocket 200 and the second empty pocket 300 from inflating rupture and forms aeroembolism, and can develop, therefore in two empty pockets all
The liquid that need to inject can develop makes its expansion.Physiological saline containing contrast agent it is filling in syringe 800 after, two syringes
The liquid injection pipe 830 of 810 head end of syringe in 800 is clamped with the first cavity 120 and the second cavity 130 respectively, and syringe 810 is placed in base
The closing piece 720 of rotation is rotated and blocks syringe 810 after 800 card slot of syringe on seat 710 and is positioned, the work in syringe 800
The tail end of plug push rod 820 is caught in the piston rod bayonet on pushing block 730, pushes pushing block 730 can be slowly to 120 He of the first cavity
Developer solution is injected in second cavity 130, fluid injection is more convenient, and can may be selected according to actual closure situation, operator
Single injection or two syringes 800 are injected simultaneously, carry out the injection of operation developer solution, side manually using device for casting 700
Just the size of the first empty pocket 200 and the second empty pocket 300 is adjusted at any time.
The middle part of the pedestal 710 is additionally provided with fixed bayonet 740, and it is solid that 810 edge of syringe of syringe 800 is caught in this
