Abstract
The utility model discloses a novel recyclable inferior vena cava filter which relates to a novel medical appliance for interventional therapy. The novel recyclable inferior vena cava filter comprises a guide head, a connecting catcher, a filtering part, a recycling connecting net, a guide rod and a sheath. The novel recyclable inferior vena cava filter is characterized in that internal threads are formed on the connecting catcher, external threads are formed on the guide rod, and the guide rod is in threaded connection with the connecting catcher; a guide hole of the guide rod is formed in the guide rod; the filtering part is formed by weaving medical metal wires; the guide head is made of flexible polymer materials; the filtering part, the connecting catcher and a memory alloy core rod are connected together in a welding mode; the recycling connecting net, the connecting catcher and the memory alloy core rod are connected together in the welding mode. The novel recyclable inferior vena cava filter has the beneficial effects that the guide rod is in threaded connection with the connecting catcher, so that capture instability or falling can be prevented; the guide hole of the guide rod is formed in the guide rod, so that when the filter is captured, because the memory alloy core rod is matched with the guide hole of the guide rod, the guide rod can be accurately butted with the connecting catcher.
Description
Affiliated technical field
The utility model relates to a kind of Novel interventional therapy medical apparatus and instruments, especially a kind of novel recyclable IVCF.
Background technology
In the prior art, both at home and abroad large quantity research finds that the recyclable filter response rate is low, and great majority are due to endothelialization or take out difficulty and use as permanent filter, fails really to demonstrate the advantage of recyclable IVCF.Technical reason: extremely tilt, angulation, owing to catching, thrombosis, filter penetration rate of blood tube wall, withdrawing device and recyclable IVCF are caught unstability to recyclable IVCF or the reason such as come off, be difficult to reclaim, also the product needed having is used special device to take out, and expense obviously increases, and patient generally also repels operation again, to use, brought inconvenience, this is the existing weak point of prior art.
Summary of the invention
The purpose of this utility model, is exactly for the existing deficiency of prior art, and a kind of technical scheme of novel recyclable IVCF is provided, and the technical program is simple in structure, easy to use, has reduced the difficulty of operation, has reduced the painful and uncomfortable of patient.
A kind of novel recyclable IVCF, comprise guide head, connect grabber, filtration fraction, recovery connection network, guide bar and epitheca, it is characterized in that: connect grabber and be provided with female thread, guide bar is provided with external screw thread, guide bar be connected grabber and connect with thread connecting mode.
Described guide bar is provided with guide bar pilot hole.
Described filtration fraction adopts the braiding of medical metal silk to form.
Described guide head material is flexible high molecular material.
Described filtration fraction, connection grabber and memorial alloy core bar link together with welding manner, reclaim connection network, connection grabber and memorial alloy core bar and link together with welding manner.
The beneficial effects of the utility model are: a kind of novel recyclable IVCF, guide bar be connected grabber and connect with thread connecting mode, can prevent from catching unstability or coming off; Guide bar is provided with guide bar pilot hole, while catching filter, due to coordinating of memorial alloy core bar and guide bar pilot hole, can make guide bar and be connected grabber and accurately dock.The technical program is simple in structure, easy to use, has reduced the difficulty of operation, has reduced the painful and uncomfortable of patient.
