4 head and the tail of interior segmental arc of segmental arc 1 and identical quantity are sequentially connected；The band of the closure formed it is planar layout, disk like layout or
Bowl-shape layout.Closure folder falls off in order to prevent, and the top of each interior segmental arc 4 is equipped at least one detent projection 3.
Band is the Ni-based shape memory alloy material of titanium, with super-elasticity, can be changed under external force under memory temperature
Become its shape, external force restores its shape memory after disappearing.
Good blood circulation is kept while overcoming tissue tension, has promoted the closure of tissue perforation internal orifice, each
At least one detent projection 2 is provided in outer arc segments 1, the fixing end and outer arc segments 1 of the detent projection 2 are connected, on-fixed
End is located in 1 area defined of outer arc segments.The detent projection 2 being arranged in outer arc segments 1 can have a variety of structures form, mainly
Four kinds of structures be:
1, the detent projection 2 in each outer arc segments 1 is one, and the top of outer arc segments 1 is arranged in and is directed to closure folder
Center.
2, two detent projections 2 arranged symmetrically in each outer arc segments 1, proper pair of the on-fixed of described two detent projections 2,
Or the on-fixed end of described two detent projections 2 is opposite and mutually stagger；The detent projection 2 by extensions arc 5 and
Corresponding outer arc segments 1 link together.
3, three detent projections 2 are symmetrical arranged in each outer arc segments 1, one of detent projection 2 is distributed in outer arc segments 1
Top and the center for being directed to closure folder, other two detent projection 2 are symmetrically distributed in outer arc segments 1.
4, four detent projections 2 are set in each outer arc segments 1, are symmetrically distributed in outer arc segments 1 two-by-two, and is mutually wrong
It opens；The outer arc segments 1 are linked together with corresponding detent projection 2 by extending arc.
In order to overcome tissue tension, the on-fixed end of the detent projection 2 in the outer arc segments 1 is stretched out where closure band
Plane or curved surface.
Gap in above-mentioned four kinds of structures between on-fixed end facing each other is 0.8-1.5mm.
In order to further fix excess tissue, 2 top of detent projection in each outer arc segments is respectively provided with spine, can pierce
Enter organization internal.
Diameter of a circle where the top of above-mentioned all outer arc segments 1 is 10-20mm, the top of all interior segmental arcs 4 or top tooth
Shape 2 place diameter of a circles of protrusion are 1-4mm；The coning angle of the band of the closure is 120-180 °.The quantity of the outer arc segments 1
It is 3 or 4, when specific demand, 5,6 or 8 can also be used.
Due to clinical different requirements, it includes positive installation and reversed installation, characteristic that internal orifice closure, which is clipped in when strutting, are as follows:
Internal orifice closure folder is strutted from center using dedicated clamping device, includes engaging teeth directional release direction on the inside of band, outside band
Lateral pedestal direction.The concave surface for being shaped to 120-160 degree, then reversely to install, is released at this time towards release direction when such as strutting
It puts, then internal orifice closure folder spring back angle is more than 90 degree；The concave surface of 120-160 degree will be shaped to when such as strutting backwards to release direction,
It is then positive installation, discharges at this time, then internal orifice closure folder spring back angle is less than 90 degree.
