Description
Technical field
This utility model relates to a kind of medical treatment device, relates in particular to a kind of using through conduit Wicresoft interventional procedure and carries and retracting device.
Background technology
The Therapeutic Method of traditional congenital structural heart disease is mainly surgical operation therapy, and by carrying out general anesthesia, surgery open chest surgery, and ligand outer circulation carry out the structural congenital defect of surgical repair.Operating shortcoming is that wound is big, the complication rate height, and postoperative leaves cicatrix, and surgery cost and costliness thereof.In recent years along with getting involved material and methodological progress, some congenital heart disease that comprises atrioventricular septal defect, patent foramen ovale and patent ductus arteriosus can be treated through the means of conduit intervention by the non-breast of opening, promptly by Wicresoft's interventional therapy, atrial septal defect plugging device, ventricular septal defect and patend ductus arteriosus occluder pass through delivery catheter through femoral venous puncture, under the image location of digital subtraction angiography, be sent to each corresponding sufferer place and repair treatment.
Specifically, Wicresoft's interventional therapy is exactly not operate on exposing under the situation of focus, on skin, blood vessel, make the minim channel of several millimeters of diameters, or through the original pipeline of human body, the Therapeutic Method of the wound minimum of under the guiding of image documentation equipment (angiography machine, fluoroscopic machine, CT, MR, B ultrasonic), the focus part being treated.Wicresoft's interventional therapy has changed the traditional surgery pattern, and it is little to have in the art wound, and postoperative does not have wound; Operation need not surgery and opens breast, and extracorporeal circulation and general anesthesia only need local anesthesia; Operative cycle is short, and post-operative recovery is fast, and the mean treatment time of every routine interventional therapy operation is less than 30 minutes, and postoperative can be left hospital in 2 to 3 days; The postoperative complication probability of happening is little; Advantages such as surgery cost reduces greatly.So Wicresoft's interventional therapy is used by increasing clinician, particularly is used widely in the treatment of cardiovascular disease.
Though interventional therapy has above plurality of advantages through conduit Wicresoft, still have many operation risks to remain to be improved.The pusher of apparatuses such as the atrial septal defect plugging device of present clinical use, ventricular septal defect and patend ductus arteriosus occluder is that front end is externally threaded conveying wirerope, and its external screw thread screws with the tail end female thread of stopper and is connected.The fit system that is threaded lacks locking function, and course of conveying reaches the risk that exists the screw thread spin to come off when location, damaged place in conduit.And the mode that is threaded needs stopper to have metal structure usually, is not suitable for the stopper of carrying nonmetallic materials (for example can absorb macromolecular material) to make.In addition, in case come off or apparatus accurately is not positioned the situation of defect, existing conveyer device can't reclaim apparatuses such as stopper.In other operative treatment stages, or postoperative follows up a case by regular visits to when finding apparatus displacement or other complication, and the method for existing Wicresoft interventional therapy does not still have the device of effective recovery apparatus, is having to adopt again surgical operation again under the situation mostly.
