Description

A kind of heart defect amplatzer
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 Side side positioning body is set, the centre of support frame as described above is provided with tank, and the bottom end of the tank is arranged in opening, described The side conduit that setting is connected with side positioning body in the tank of supporting rack, the side conduit are used for into side positioning body It injects fluid and it is forced to expand or be flared out outward.
In the present invention, one end connect the side positioning body of the side conduit, filled rubber plug in the other end.
In the present invention, further include upper positioning body and lower positioning body, predeterminable shape is arranged in the upper end of support frame as described above Upper positioning body, the lower end of support frame as described above are arranged the lower positioning body of predeterminable shape, the side positioning body, upper positioning body and under The combination of positioning body forms the sacculus of integral structure, and the sacculus includes an opening, and support frame as described above is arranged in sacculus Opening, on the inside of support frame as described above and sacculus between form the cavity of a sealing, on support frame as described above setting for cavity into Enter or flow out the pipeline of fluid.
In the present invention, the side positioning body, upper positioning body and lower positioning body are interconnected, and are conveyed by a conduit Fluid make side positioning body, upper positioning body and lower positioning body simultaneously outward expansion and shrink or side positioning body, upper positioning body and Lower positioning body is not connected to mutually or only two of which is connected to, and passes through more than two Pipeline transport fluids.
In the present invention, further include that upper conduit, downcomer, upper positioning body and lower positioning body, the upper end of support frame as described above are set The upper positioning body of predeterminable shape is set, the lower positioning body of predeterminable shape is arranged in the lower end of support frame as described above, support frame as described above The upper conduit being connected with upper positioning body is provided in tank, and the downcomer being connected with lower positioning body, with upward respectively Positioning body forces it to expand or be flared out outward with fluid is injected in lower positioning body.
In the present invention, one end of the upper conduit connects upper positioning body, filled rubber plug in the other end;The downcomer The lower positioning body of one end connection, filled rubber plug in the other end.
In the present invention, further include upper positioning body, downcomer and lower positioning body, the upper end setting of support frame as described above is predeterminable The upper positioning body of shape, the upper positioning body are connected to side positioning body, and the lower end of support frame as described above is arranged under predeterminable shape Positioning body is provided with the downcomer being connected with lower positioning body in the tank of support frame as described above, is being positioned downwards by downcomer It injects fluid in vivo and it is forced to expand or be flared out outward.
In the present invention, the lower positioning body of one end connection of the downcomer, filled rubber plug in the other end.
In the present invention, further include upper positioning body and lower positioning body, upper positioning body is arranged in the upper end of support frame as described above, described The lower positioning body of lower end setting of supporting rack, the upper positioning body and lower positioning body are respectively communicated with side positioning body.
In the present invention, on the outer wall of support frame as described above be arranged quantity be it is more than two for store side positioning body, Upper positioning body and/or lower positioning body reduce the groove of heart defect amplatzer volume.
Advantageous effect
1, side positioning body is arranged in the side of supporting rack in the present invention, when in use, is being lacked to patient's heart by instrument After damage position is scanned, holder can be formed by way of 3D printing die sinking, be positioned at this time since side being arranged on holder Body can change the size of heart defect amplatzer radial direction, 3D printing is made to go out by way of inflation or fliud flushing body Supporting rack do not need degree of precision and can reach the effect most preferably identical with patient's defect;
2, on the outer wall of supporting rack be arranged quantity be more than two grooves, can realize upper positioning body, lower positioning body and Side positioning body is accommodated under negative pressure state in groove, can reduce the volume of heart defect amplatzer, is reached and is convenient for heart Defect plugging device is put into the effect of patient's heart defect.
