Description
Technical field
The present invention relates to a kind of medical heart defect plugging devices, it particularly relates to a kind of being suitable for minimally invasive closure operation,
And surgical procedure is convenient and efficient, the safer novel heart septal defect blocking device of use can be used for repairing acleistocardia
(PFO), atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA) etc..
Background technology
Congenital heart disease includes patent ductus arteriosus (PDA), acleistocardia (PFO), atrial septal defect (ASD) and room
It is interior every defect (VSD) etc..PDA can cause blood to be flowed between aorta and pulmonary artery.PFO and ASD can cause blood on a left side
It is flowed between atrium and atrium dextrum.VSD can cause blood to be flowed between left ventricle and right ventricle.When flow is more, generally need
It repairs.Since the 1970s, by heart defect amplatzer, the interventional therapy that the defect of heart is blocked
Extensive popularization is obtained.
In the prior art, heart defect shape is non-standard shapes, and traditional method mainly passes through preformed or the side of 3D printing
Formula produces the heart defect amplatzer to match with heart defect position, and heart defect portion is being sent into the closure by instrument
Behind position, front and back positioning is carried out to the heart defect amplatzer by the plugging film at heart defect amplatzer both ends, is used with reaching
Effect；But since heart defect amplatzer needs to be set in heart defect position, the radial dimension of defect object is excessive
When, heart defect amplatzer is difficult to be set in heart defect position, and when too small, best match result is not achieved；For this purpose, to
Reach best match result, can only be realized by the way of improving closure precision, cause cost excessively high；Especially lacked in heart
When damage position is abnormity, preferable and match result is extremely difficult between heart defect amplatzer and heart defect position.
It is accordingly required in particular to a kind of heart defect amplatzer, to solve problems of the prior art.
Invention content
The purpose of the present invention is to solve in the prior art, since the structure setting of heart defect amplatzer is unreasonable,
The defect with the best match result in heart defect position is not achieved, a kind of heart defect amplatzer is provided, to solve the prior art
The problem of.
To achieve the above object, technical scheme is as follows：
A kind of heart defect amplatzer, including supporting rack further include the side positioning body of predeterminable shape, support frame as described above
