Abstract
A kind of artificial heart inlet attack preventing intra-ventricle thrombus, belongs to biomedical engineering field.The connector is made of drainage head, bridge piece and suture ring.Wherein inside drainage head insertion left ventricle, surface is uniformly distributed equirotal conduction hole, is used for from uniform suction blood around;Bridge piece has physiological bending for connecting drainage head and artificial heart ontology, according to cardiac shape;Suture ring is fixed on bridge piece outer layer, for being sutured with cardiac muscle, fixed entire connector.One aspect of the present invention can be effectively reduced the flow dead zone in left ventricle, reduce the risk that thrombus occurs for intra-ventricle, another aspect conduction hole can effectively prevent intra-ventricle thrombus to enter inside artificial heart, to improve the safety of artificial heart.
Description
Technical field
The present invention relates to a kind of artificial heart inlet attacks for preventing intra-ventricle thrombus, belong to biomedical engineering field.
Background technique
Artificial heart has been increasingly becoming one of the effective ways for the treatment of heart failure, and the blood occurred in use process
Bolt complication significantly limits the clinical application of artificial heart and the quality of life of patient.Artificial heart inlet attack protrudes into
Blood is extracted in left ventricle.Since traditional jointing has a very strong directionality to the attraction of blood, thus can fitting inlet with
Flow dead zone is generated between ventricle wall, to cause thrombosis.On the other hand, because traditional artificial heart fitting inlet is
Open design, intra-ventricle thrombus are easy to enter inside artificial heart together with blood flow, to cause the operation event of artificial heart
Barrier.Although traditional artificial heart inlet attack has the above problem, still asked at present without related invention with this is researched and solved
Topic.
Summary of the invention
The purpose of the present invention is designing a kind of artificial heart inlet attack for preventing intra-ventricle thrombus, solves the prior art and ask
Topic.
The technical solution adopted by the present invention to solve the technical problems, the present invention are a kind of to prevent the artificial of intra-ventricle thrombus
Heart inlet attack, with specific reference to Fig. 1, including drainage head (1), bridge piece (2), suture ring (3), drainage head (2) shape is
The hollow elliposoidal expanded, surface are uniformly distributed conduction hole through-hole for suction blood uniform around drainage head (2), drainage head
(1) it is located at intra-ventricle, drainage head (1) long axis one end connects and is fixed together in intra-ventricle with bridge piece (2) one end,
And long axis, the same straight line of bridge piece (2) central axis of junction drainage head (1);The bent angle and the other end of bridge piece (2) are in the heart
It is outdoor;Suture ring (3) are equipped in the junction of the external bend pipe of ventricle (2) Yu ventricle wall (4), suture ring (3), which covers, is connecing bend pipe (2)
Outer integralization, and suture ring (3) is fixed together with ventricle wall (4), reaches the immobilization for connecing bend pipe (2) Yu ventricle wall (4).
The contact position for connecing bend pipe (2) Yu ventricle wall (4) connects the central axis ventricle wall (4) of bend pipe (2).
Drainage head material is titanium alloy material;Bent angle on bridge piece is curved with being adapted with cardiac anatomy
Angle, for connecting artificial heart ontology and drainage head (1), material is titanium alloy material, and bent angle range is 30-90 °;Suture ring
It is fixed on and has connected head outer wall, be artificial vascular grafts for being sutured with cardiac muscle.
On the one hand blood that the device is capable of uniform draw ambient reduces ventricle to eliminate flow dead zone inside ventricle
Interior thrombosis risk;On the other hand, which can effectively prevent the thrombus formed and enter inside artificial heart, ensure
The safety of artificial heart operation.
Detailed description of the invention
A kind of artificial heart inlet attack for preventing intra-ventricle thrombus of Fig. 1.
1. drainage head;2. bridge piece;3. suture ring;4. ventricle wall.
Specific embodiment
Below with reference to embodiment, the present invention will be further described, but the present invention and is limited to following embodiment.
Embodiment 1
In a kind of artificial heart inlet attack for preventing intra-ventricle thrombus of the invention, drainage head is elliposoidal, long axial length
30mm, minor axis length 22mm, wall thickness 1mm are spent, bore dia 1mm, spacing 0.5mm are drained;Bridge piece diameter 16mm, length
40mm, 50 ° of wall thickness 1mm of bent angle;Suture ring is artificial vascular grafts, internal diameter 16mm, outer diameter 18mm, height 2mm.By external real
It tests and animal experiment study, the blood which can uniformly around aspiration drainage head eliminates intra-ventricle blood flow flow dead zone;
And thrombus can be effectively prevent to enter artificial heart.
