Description
Technical Field
The utility model relates to the technical field, in particular to an artery puncture point plugging device.
Background
With the advancement of interventional materials, neural intervention has progressed and will continue to be the primary method of treating cerebrovascular disease. The Seldingers method is used for intravascular intervention treatment of vascular related diseases by being placed in a femoral artery sheath, is widely applied to nerve intervention, cardiac intervention or other vascular interventions, and traditionally adopts local compression hemostasis of puncture points after sheath removal. The interventional therapy of cerebrovascular diseases is usually associated with the medication of anticoagulation, fiber reduction, platelet aggregation resistance and the like, so that the actual hemostasis of the arterial puncture point is particularly important. In the prior art, hemostasis is performed by using a nail-shaped embolism colloid, wherein the nail-shaped embolism colloid is divided into a nail head and a nail rod; when the nail head part is pushed by the controllable push rod to be exposed to blood in a blood vessel, after the nail head part expands to be larger than the diameter of the artery sheath, the blood vessel plugging device and the artery sheath can be pulled out together, the expanded nail head colloid is blocked in the blood vessel by the narrow blood vessel puncture point, meanwhile, the side pressure caused by blood flow presses the inner wall of the blood vessel, the expanded nail head part is filled outside the puncture point and the blood vessel, and the blood vessel puncture point is riveted by the embolism colloid to prevent bleeding and embolism from moving alternately. However, the application of the nail-shaped embolic gel inevitably enlarges the blood vessel puncture point, and the fixation of the nail-shaped embolic gel depends on the narrow blood vessel puncture point and the compression of lateral pressure formed by blood flow velocity, and the nail-shaped embolic gel also risks loosening and forming thrombus.
The Chinese patent application: CN109009300A discloses a femoral artery puncture point plugging hemostat, which comprises a propeller and an absorbable plug; the absorbable plug is arranged in a pushing pipe of the propeller; also comprises a memory alloy net; the memory alloy net is sleeved outside the absorbable plug, and the far end of the memory alloy net is flush with the far end of the absorbable plug. The femoral artery puncture point plugging hemostat comprises a propeller and an absorbable plug; the absorbable plug is arranged in a pushing pipe of the propeller; the method is characterized in that: also comprises a memory alloy net; the memory alloy net is sleeved outside the absorbable plug, and the far end of the memory alloy net is flush with the far end of the absorbable plug; this patent technical scheme can absorb the plug and send to blood vessel thorn mouthful outer wall along the sheath pipe, absorb water inflation oppression blood vessel and promote the clot formation through can absorbing the plug, reach hemostatic effect, but it still realizes stanching through oppression blood vessel, and its hemostatic effect is relatively less.
