Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of vena cava filter and its recyclable device.
Background technique
Deep vein thrombosis (DVT) formation is common vascular surgery disease, and the complication of most serious falls off for embolus draws
Vena cava filter implantation inferior caval vein can be prevented pulmonary embolism by the mortality pulmonary embolism (PE) risen.It is implanted into vivo according to filter
Time, filter can distinguish following two: permanent filter and recyclable filter.Recyclable filter need to be recycled by vena cava filter
Device is recycled.
Vena cava filter currently on the market is generally welded by two or more components；It is main to utilize the round recycling of band
The vena cava filter recyclable device of circle recycles vena cava filter.
The major defect of this vena cava filter is: after filter implants, welding position is easy to be corroded, risk
It is high；It is big to recycle resistance；Filter, which enters sheath difficulty, to be caused to be not easily recycled；Filter is easy inclination and displacement, and return period is short；Filter is to blood
Hemodynamics change the generation for leading to iatrogenic thrombus.When the recycling loop diameter of vena cava filter recyclable device is straight greater than blood vessel
Diameter or the nonstandard quasi-circular of vascular cross-section, recycling circle can not fully open, be deformed, be not easy to arrest foreign matter.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of vena cava filter and its recyclable device, eliminate because of welding
Bring risk is corroded at position, effectively improves the stability in vena cave, while again convenient for recycling.
The present invention is implemented as follows: a kind of vena cava filter, including connection pipe body, connection pipe body have phase in the axial direction
Pair two ends, one of end is equipped with eccentric recovering hook, the other end is equipped with the axially distributed several layers body of rod；Bar
Center line of the end of body far from connection pipe body is to make vena cava filter at umbrella-shaped structure；The one layer bar nearest apart from recovering hook
Body is quarter butt, number at least four, and is uniformly distributed circumferentially；The one layer body of rod farthest apart from recovering hook is stock,
Its number is at least three, and is uniformly distributed circumferentially, and the end of stock is equipped with the barb two towards outside；Positioned at quarter butt and
The several layers body of rod between stock is middle bar, and the end of middle bar is equipped with the barb one towards outside.
Further, the barb one of middle bar is crotch, and the barb two of stock is straight hook.
Further, recovering hook is first to upwardly extend streamlined structure made of bending still further below as the end of connection pipe body
Body.
Further, connection pipe body, recovering hook and the body of rod are integrally connected.
Further, the material of connection pipe body, recovering hook and the body of rod is Nitinol.
Further, the number of quarter butt is four, six or eight, and the number of middle bar is three, and the number of stock is three.
The invention also discloses a kind of recyclable device, for recycling vena cava filter from vena cave, including device noumenon,
Casing, traction rope and recycling coil assembly, device noumenon connect one end of traction rope, and the other end of traction rope is after casing and returns
It receives coil assembly to be connected, recycling coil assembly includes at least one deformable recycling circle；Recycling circle is ellipsoidal structure, long axis
One end connection traction rope, the other end form pointed protruding portion.
Further, the number for recycling circle is one, and major axis dimension is 0~40mm, and minor axis dimension is 0~40mm.
Further, the number for recycling circle is three and forms even circumferential distribution, and width dimensions are 0~40mm,
Height dimension is 0~40mm.
Further, the number for recycling circle is one, and major axis dimension is 23~24mm, and minor axis dimension is 20~21mm.
Further, the number for recycling circle is three and forms even circumferential distribution, and width dimensions are 20~21mm,
Height dimension is 23~24mm.
Further, recycling circle is made of Nitinol.
The invention has the beneficial effects that:
1. vena cava filter is made of integral forming process, eliminate in the prior art because of groove corrosion bring
Risk improves the safety in diagnosis and treatment process；Additionally due to eliminating corrosion, return period can be increased；
2. the recovering hook of vena cava filter is streamlined structure, reduce recycling resistance, and unsymmetric structure can make to recycle
Circle is easier to hook recovering hook, and filter caused by can eliminating because of filter axis different with recycling circle enters the problem of sheath difficulty；
3. the body of rod of vena cava filter is multilayered structure, and the end of quarter butt and stock is equipped with barb, can effectively prevent
Inclination and displacement improve stability of the filter in vena cave；
4. the recycling circle of recyclable device is non-circular structure, it is greater than vena cave blood vessel diameter or blood vessel in recycling loop diameter
When the nonstandard quasi-circular in section, it can be easier capture filter, realize the recycling of filter；
5. using new structural recovering hook, it is more easier to be recovered device capture, improves recovery efficiency；Due to filter
For integral type hollow structure, reduce the generation of the iatrogenic thrombus as caused by hemodynamic change.
