Affected part, and timing Long-term taking medicine is needed, there is serious damage to the hepatic and renal function of patient.
Summary of the invention
The purpose of this utility model is: thrombus acquirer is provided, to overcome above-mentioned defect in the prior art.
Technical solution used by the utility model is:
The utility model provides a kind of thrombus acquirer, is characterized in that in including being successively set with from inside to outside
Sheath, middle sheath and outer sheath, the interior sheath is interior to be arranged seal wire, and the first capture net, institute are arranged between outer sheath and middle sheath
It states the first capture net to fix with mesotheca pipe outer wall, the second capture net, the second capture net is set between middle sheath and interior sheath
It is fixed with seal wire.
Further, the first capture net is funnel-shaped, and the net bottom of the first capture net is fixed with mesotheca pipe outer wall.
Further, the second capture net is funnel-shaped, and the network interface of the second capture net passes through outside limiting wire and interior sheath
Wall is fixed, and the net bottom of the second capture net is fixed with seal wire.
Further, more reinforcing wires are arranged in the first capture net and the second capture on the net.
Further, the network interface of the first capture net and the network interface of the second capture net are positioned opposite.
Further, described seal wire one end is water-drop-shaped structure.
Further, the network interface is made of medical silica-gel.
Further, the interior sheath, middle sheath, outer sheath and seal wire are made of memory metal.
Further, the diameter of the network interface is 5-20mm.
The beneficial effects of the utility model are: netting the thrombus and impurity collected in blood using capture in the technical program
Fragment directly acts on affected part, safe and efficient.
Detailed description of the invention
Fig. 1 is structural schematic diagram provided in this embodiment；
Fig. 2 is working state schematic representation provided in this embodiment；
In figure, sheath in 1-, sheath, 3- outer sheath, 4- seal wire, 5- first capture net, 6- second captures net in 2-, 7- limit
Position silk, 8- reinforcing wire, 9- water-drop-shaped structure.
Specific embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described.
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
As Figure 1-Figure 2, the present embodiment provides a kind of thrombus acquirers, including the interior sheath being successively set with from inside to outside
1, middle sheath 2 and outer sheath 3, interior sheath 1 is interior to be arranged seal wire 4, and the first capture net 5 is arranged between outer sheath 3 and middle sheath 2, the
One capture net 5 is fixed with middle 2 outer wall of sheath, between middle sheath 2 and interior sheath 1 be arranged second capture net 6, second capture net 6 and
Seal wire 4 is fixed.
Preferably, the first capture net 5 is funnel-shaped, and the net bottom of the first capture net 5 is fixed with middle 2 outer wall of sheath.
Preferably, the second capture net 6 is funnel-shaped, and the network interface of the second capture net 6 passes through limiting wire 7 and interior 1 outer wall of sheath
Fixed, the net bottom and seal wire 4 of the second capture net 6 are fixed.
Preferably, more reinforcing wires 8 are set on the first capture net 5 and the second capture net 6.
Preferably, the network interface of the first capture net 5 and the network interface of the second capture net 6 are positioned opposite.
Preferably, 4 one end of seal wire is water-drop-shaped structure 9.
Preferably, network interface is made of medical silica-gel.
Preferably, interior sheath 1, middle sheath 2, outer sheath 3 and seal wire 4 are made of memory metal.
Preferably, the diameter of network interface is 5-20mm.
Working principle is as follows: under the auxiliary of angiography, by thrombus acquirer by puncturing merging patient vessel, passing through
Rotation, pull outer sheath are placed in the first capture net and the second capture net in target area, pull outer sheath, release first is caught
Net is obtained, seal wire is pushed into, release the second capture net collects the thrombus and fragment in blood, stands a period of time, is pushed into outer sheath,
Recycling the first capture net pulls interior sheath, recycling the second capture net, removal of thromboses acquirer.
Wherein, seal wire one end is water-drop-shaped structure, is prevented during rotating pull, the blood as caused by undue force
Vessel wall damage, network interface are made of medical silica-gel, have good biocompatibility and ductility, and it is multiple to can adapt to internal blood vessel
Miscellaneous environment, in addition, interior sheath, middle sheath, outer sheath and seal wire are made of memory metal, amount of bow is big, and plasticity is high, is convenient for
Thrombus acquirer is in venous blood in-pipe.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power
Subject to the protection scope that benefit requires.
