Abstract
A kind of artificial heart spigot joint for preventing ventricle wall from blocking, belongs to biomedical engineering field.The connector is made of drainage tube, bracket and suture ring.Wherein bracket is fixed on drainage tube leading portion outer wall, and drainage tube and bracket protrude into inside left ventricle；Bracket is used in the fixed drainage tube of intra-ventricle, and supports ventricle wall, prevents ventricle wall blocking drainage tube inlet；Drainage tube, which is used to extract blood out of left ventricle, enters artificial heart；Suture ring is fixed on drainage outer tube layer, for being sutured with cardiac muscle, fixed entire connector.The present invention can effectively solve the problem that the problem of ventricle wall blocks artificial heart entrance, improve the stability of artificial heart, reduce influence of the ventricle suction to artificial heart.
Description
Technical field
The present invention relates to a kind of artificial heart spigot joints for preventing ventricle wall from blocking, and 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 in clinical application, manually
Heart extracts blood via the intubation of insertion left ventricle, and is pumped into body circulation.Traditional artificial heart inlet cannula is mainly adopted
It is fixed with suture way and cardiac muscle, drainage tube unprotect measure inside cardiac muscle.Due to the swabbing action of artificial heart, can insert
Tube inlet generates low-pressure area, thus attract nearby ventricle wall and then block catheter entrance close to catheter entrance, in turn result in artificial
Heart blood supply interrupts, directly threat patient vitals.
Summary of the invention
The purpose of the present invention is designing a kind of artificial heart spigot joint for preventing ventricle wall from blocking, the prior art is solved
Problem.
The technical solution adopted by the present invention to solve the technical problems, a kind of artificial heart intubation for preventing ventricle wall from blocking
Connector, with specific reference to Fig. 1, including bracket (1), drainage tube (2), suture ring (3).
Bracket (1) is located at intra-ventricle；Bracket (1) is hollow structure substantially symmetrical about its central axis, including upper and lower two parts, upper part
For the peripheral circles skew back face of rotary table A, lower part is divided into the peripheral circles skew back face of rotary table B, and the corresponding upper port diameter of rotary table A is small
In lower port diameter, the corresponding upper port diameter of rotary table B is greater than lower port diameter, the corresponding large port diameter of rotary table A and rotary table B
Corresponding large port diameter is equal, and the corresponding portlet diameter of rotary table A portlet diameter corresponding with rotary table B is equal, and A pairs of rotary table
The side of the large port answered large port corresponding with rotary table B is fixed together；The corresponding portlet of rotary table B is bonded ventricle wall
(4)；One end of drainage tube (2) is deep into intra-ventricle outside ventricle, sequentially passes through through A pairs of the rotary table of the corresponding portlet of rotary table B
The portlet answered；In ventricle drainage tube (2) and ventricle wall (4) junction, the periphery of drainage tube (2) is cased with a suture ring (3)
Be integrally fixed structure with drainage tube (2), suture ring (3) is fixed together with ventricle wall (4) so that drainage tube (2) with
Ventricle is integrally fixed；A bent angle is equipped in ventricle drainage tube (2).
It is preferred that the height of rotary table A is greater than the height of rotary table B.
The corresponding portlet diameter of rotary table B is equal with the overall diameter of drainage tube (2).
In drainage tube (2) and ventricle wall (4) junction, the central axis ventricle wall (4) of drainage tube (2).
Drainage tube (2) bent angle is with the bent angle being adapted with cardiac anatomy, and angular range is 30-90 °, material
Matter is titanium alloy material.
It radially, is hollow between bracket (1) and drainage tube (2).
Bracket (1) is that memory wire weaves, and forms compressible stent.Bracket is fixed on outside drainage pipe leading portion
Wall, middle section are expanded along drainage tube radial direction, for the position of fixed cardiac muscle and drainage tube, prevent drainage tube from shifting
Or myocardium wrinkle blocking drainage tube inlet.
Drainage tube, which is used to extract blood from intra-ventricle, enters artificial heart；Suture ring is fixed on drainage pipe outer wall, for
Cardiac muscle suture, suture ring are artificial vascular grafts.
The device effectively solves the problems, such as that ventricle wall blocks artificial heart entrance, improves the stability of artificial heart, reduces
Ventricle aspirates the influence to artificial heart.
Detailed description of the invention
A kind of artificial heart inlet attack for preventing intra-ventricle thrombus of Fig. 1.
1. bracket；2. drainage tube；3. suture ring；4. ventricle wall.
Specific embodiment
Below with reference to embodiment, the present invention will be further described, but the present invention is not limited to following embodiments.
Embodiment 1
In a kind of artificial heart inlet attack for preventing intra-ventricle thrombus of the invention, bracket be memory alloy wire weave and
At alloy wire diameter 0.2mm.Mid-stent is expanded outside along drainage tube outer radial, enlarged diametric 10mm, support height 20mm；
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 experiment in vitro and animal experiment study, after artificial heart level of suction increase, ventricle wall direction is drawn
Flow tube entrance is mobile, but is supported by bracket, avoids ventricle wall obstruction drainage tube inlet, and due to having bracket support, people
Work heart inlet cannula can be fixed in ventricle wall, and there is no movements.
