Wirerope 14 far-ends can adopt any suitable mode with being connected of stopper 16, as long as can discharge stopper 16 in defect.In a kind of preferred embodiment, wirerope 14 far-end welding M0.8*1.5 Micro-bolts 15, wirerope 14 is connected with stopper 16 by bolt 15.Thereby can connect by spiral, after propelling movement carried wirerope that stopper is placed in the defect of heart, rotation carried wirerope can discharge stopper.
Preferably, the effective length through breast Wicresoft stopper induction system of the present utility model is only 1/3rd of percutaneous puncture stopper induction system effective length, therefore is applicable to through the breast Minimally Invasive Surgery.
Beneficial effect:
1. apparatus is short and small: the effective length of this stopper induction system is 1/3rd of percutaneous puncture stopper induction system effective length,, because clinical path shortens greatly, farthest avoided intervention apparatus to push damage risk between blood vessel and heart inside.
2. one man operation: because apparatus is short and small, can be in-plant near diseased region, singlely can realize the processes such as puncture, track foundation, direction adjustment, shutoff release, must complex operations, avoid the operational risk of bringing because of complicated operation.
3. radiationless injury: only need ultrasonic guidance, need not to operate under X ray.To patient and all radiationless harm of operator.
4. reduce costs, economize on resources: the effective length of this induction system is 1/3rd of original length, and the raw material that manufactures a product reduces, and then reduces costs, economizes on resources.
5. mini-incision, preventing from scar:, because otch is less, need not to sew up.
6. the small and exquisite exquisiteness of hemostasis device, coordinate to arrange in pairs or groups, coordinate moderate with whole induction system.
7. if shutoff failure, can further extend otch and change the conventional thoracotomy operation into, need not separately to do otch or shift the patient, can farthest guarantee patient safety.
