It will not deform, it is minimum for the wound of blood vessel, belong to Minimally Invasive Surgery, effectively reduces because of infection of incisional wound, blood caused by cutting, suturing
The complication such as narrow, bleeding, thrombosis are managed, delivery location is accurate, easy, does not need to adjust conduit and mesh basket position repeatedly.
It is a kind of it is disposable take bolt mesh basket, including conduit, seal wire, mesh basket takes bolt mesh basket seal wire portion；It is characterized in that institute
Mesh basket is stated in coniform, bottom is equipped with the aperture passed through for seal wire；The mesh basket opening is symmetrically equipped with two lifting ears；It mentions
The twine for drawing ear and network interface avris to be integrally formed, and lift ear mesh basket intersection is coarser than the twine at other positions, makes network interface in V word
Shape openning shape, and can ensure that the opening of mesh basket possesses certain support hardness, thrombus is easier to enter in mesh basket；It is described to mention
It draws the top of ear free margins to be connected with and takes bolt mesh basket seal wire portion, and bolt mesh basket seal wire portion is taken to be symmetrically located in the middle part of mesh basket；Institute
Stating conduit can bend to any direction, and conduit during taking bolt is avoided to cause to damage to blood vessel with blood vessel friction, cause interior
Membrane damage and bleeding；The straight end for taking bolt mesh basket seal wire portion to pass through conduit is pierced by from conduit bent-up end；It is described to take bolt mesh basket seal wire
Portion is tubulose, and is equipped with hole in the furcation for taking bolt mesh basket seal wire portion；The seal wire is penetrated from mesh basket bottom circular aperture by taking bolt
The hole in mesh basket seal wire portion is simultaneously pierced by the free end for taking bolt mesh basket seal wire portion.
Preferably, the mesh basket is circular hole mesh basket, when pulling in mesh basket in conduit, reduces the resistance of mesh basket and conduit mouth
Power, convenient for pulling in and pulling out.
Preferably, the inner ring of the straight end end face of the conduit is set as chamfering, and outer ring is set as rounding, guarantees that mesh basket is pulling in net
It is not easy when pipe by card column, while conduit being avoided to damage blood vessel.
The beneficial effects of the utility model are to carry out arteriopuncture intervention mainly for artery of lower extremity acute thrombus patient
Use when taking bolt to treat after detecting, can effective filtering blood, it is easy simultaneously for arresting for thrombus, take bolt number less, and
Take bolt clean, while being able to maintain mesh basket during capturing thrombus to deform, it is minimum for the wound of blood vessel, belong to micro-
Invasive procedures are effectively reduced because of complication such as infection of incisional wound, hemadostewnosis, bleeding, thrombosis caused by cutting, suturing, are sent to
Position is accurate, easy, does not need to adjust conduit and mesh basket position repeatedly；In addition, bolt mesh basket seal wire portion will be taken to be arranged in mesh basket
Portion position keeps mesh basket mesh basket transversal cross-section during filtering bolt vertical with blood vessel holding always, protects effective filtration area always
It holds maximum, lifts fixed form flat, the guarantee blood that squeeze mesh basket will not by the resistance of blood during filter bolt of ear and mesh basket
Bolt will not be missed from blind area, reduce the number of filter bolt, and then reduce and take bolt mesh basket secondary injury caused by blood vessel.

Specific embodiment
As shown, it is a kind of it is disposable take bolt mesh basket, including conduit 1, seal wire 2, mesh basket 3 takes bolt mesh basket seal wire portion
4；It is characterized in that the mesh basket 3, in coniform, bottom is equipped with the aperture passed through for seal wire 2；3 opening of mesh basket is symmetrical
Be equipped with two lifting ears 5；It lifts ear 5 and network interface avris is integrally formed, and the twine for lifting 5 mesh basket of ear, 3 intersection is coarser than other
The twine at position makes network interface be in the shape of the letter V openning shape, and can ensure that the opening of mesh basket 3 possesses certain support hardness, and thrombus is more
It is easily accessible in mesh basket 3；The top of lifting 5 free margins of ear, which is connected with, takes bolt mesh basket seal wire portion 4, and takes bolt mesh basket seal wire
Portion 4 is symmetrically located in the middle part of mesh basket 3；The conduit 1 can be bent to any direction, avoid during taking bolt conduit 1 with
Blood vessel friction causes to damage to blood vessel, causes inner film injury and bleeding；The straight end for taking bolt mesh basket seal wire portion 4 to pass through conduit 1
It is pierced by from 1 bent-up end of conduit；It is described to take bolt mesh basket seal wire portion 4 for tubulose, and hole is equipped in the furcation for taking bolt mesh basket seal wire portion 4；
The seal wire from 3 bottom circular aperture of mesh basket penetrate the hole by taking bolt mesh basket seal wire portion 4 and be pierced by take bolt mesh basket seal wire portion 4 from
By holding.
Preferably, the mesh basket 3 is circular hole mesh basket, when pulling in mesh basket 3 in conduit 1, reduces mesh basket 3 and conduit 1
The resistance of mouth, convenient for pulling in and pulling out.
Preferably, the inner ring of the straight end end face of the conduit 1 is set as chamfering, and outer ring is set as rounding, guarantees that mesh basket 3 is pulling in
It is not easy when network management by card column, while conduit 1 being avoided to damage blood vessel.
Bolt mesh basket 3 is taken, thickening layer is arranged in lifting ear 5 and 3 open edge of mesh basket, network interface can be made in the mistake of entirely filter bolt
There is biggish tension in journey, so that network interface is in the state dehisced always, maximize effective area, while bolt mesh basket will be taken to lead
Silk portion 4 is fixed on lifting 5 top of ear and is located at the medium position of mesh basket 3, it is ensured that mesh basket 3 will not go out during filtering bolt
It now overturns, guarantees that the transversal cross-section of mesh basket 3 is vertical with blood vessel always, the misgivings area of mesh basket 3 is maximized, reduce filtering time
Number, and then reduce and injured caused by blood vessel.
Application method: being placed in vagina vasorum pipe after conventional puncture vessel, into seal wire 2, enters conduit 1 along seal wire 2, and will lead
Silk 2, conduit 1 are sent into vascular thrombosis distal section, enter in conduit 1 along seal wire 2 and take bolt mesh basket 3, it is close that conduit 1 is gradually removed thrombus
End will take bolt mesh basket 3 to be slowly pulled in conduit 1 to proximal segment after going bolt mesh basket 3 to be fully deployed automatically due to the effect of grid elastic force, will
Thrombus loading takes in bolt mesh basket 3, withdraws from vitro, can take out thrombus along seal wire 2, the few destruction for blood vessel of structure
Small, high-efficient, effect is good.
