Description
Technical field
The invention belongs to insertion type technical field of medical instruments, is related to a kind of unobstructed medical ball of cardiac valves implanted
Capsule.
Background technology
In recent years, with the progress of interventional therapeutic technique, obtained quickly through catheter heart valves displacement or prosthetic
Develop and be applied to clinic, achieve more satisfied effect.Performed the operation by minimally invasive intervention by insertion type artificial cardiac valve branch
Frame is implanted in the bicuspid valve or aorta petal of heart by balloon expandable, and phase is carried out to replace or repair the natural valve of infringement
Close work.Insertion type artificial cardiac valve mainly includes support, and is arranged at the leaflet of internal stent, is pressed and is held in sacculus
On, by the full expansion of sacculus, cardiac valves is strutted the original native valve of displacement.In terms of PCI, sacculus rises
To very crucial effect so that interventional therapeutic technique process need not open chest, thus wound is small, post-operative recovery is fast.For those mesh
Preceding conventional therapy means can not extend its life or alleviate its painful valve stenosis patient, and sacculus interventional therapeutic technique provides
A kind of new solution.
CN 102921095A disclose a kind of new passability valve or Angiectasis sacculus, by sacculus be fabricated to by
Center guide wire to periphery airbag aeration, and have between seal wire and periphery air bag the straight-through tube chamber of multiple stringers be used for blood flow by,
In inflatable dilatation narrow zone, still there is blood flow in tube chamber by supplying distal end internal organs, but it is made up of single sacculus, easily
In cause sacculus to slide the problem of.
CN 103622769A disclose a kind of three leaf-head capsules for spreading belt valve aorta petal support, including autumn nanmu
Sacculus, conduit and joint, the sacculus is connected by three single saccules by side to be formed, and is passed through among three single saccules
Seal wire, the conduit stretch out sacculus and are broken down into two-chamber joint, gas tube and the gas transmission orifice of the conduit, the gas transmission
Orifice air-source or water source, the air-source or water source connect sacculus by gas tube；Yet with the sacculus by three
Single saccule is formed, and unbalance stress is likely to result in balloon expandable, is still likely to result in sacculus displacement, or even heart is made
Into added burden.
In summary, the problem of more is also faced currently used for the sacculus in interventional therapeutic technique, during application.Such as sacculus
Easily slide；Sacculus fills expanse process and easily causes cardiac flow blocking, it is necessary to use temporary pacemaker etc. for patient.Pin
To problem existing for sacculus used in existing insertion type, those skilled in the art always search for the method solved.
The content of the invention
In view of the shortcomings of the prior art, it is an object of the invention to provide a kind of unobstructed medical ball of cardiac valves implanted
Capsule, it is blocked with solving existing blood flow direction during existing heart valve prosthesis implanted balloon expandable, it is necessary to using facing
When pacemaker and sacculus the problem of easily sliding.
To reach this goal of the invention, the present invention uses following technical scheme：

(7) connect, the sub- balloon distal (5) is connected on conical head (6)；Locate each other the center section (8) of each bulbec capsule
In adhesion state, and tangent state is in each other when bulbec capsule is full, successively around forming 360 degree, centre forms cavity.
The medical balloon of the present invention, in PCI, the full process of conventional balloon expansion can be avoided to block blood flow
Problem, blood flow can be flowed after sacculus expansion by the cavity formed between bulbec capsule, will not occur to block blood flow
The problem of, further, since using more than 5 bulbec capsules, it can allow and reach when sacculus fills close to circular arc
Uniform state so that uniform force, be not easy to slide, the use of high polymer material fabric in addition also further avoid due to ball
Capsule surface is smooth and the problem of easily slide, and also will not be that heart cause extra injury, improve success rate of operation.
In the present invention, the sub- balloon proximal (4) of each bulbec capsule is not connected to each other, the son of each bulbec capsule
Balloon distal (5) is not connected to each other, and when bulbec capsule is full, sub- balloon proximal (4) forms what is connected with the cavity to each other
Gap, sub- balloon distal (5) form the gap connected with the cavity to each other.
In the present invention, the gap that sub- balloon proximal is formed and the gap that balloon distal is formed and the center section of bulbec capsule
The cavity surrounded forms path so that blood flow can smoothly circulate, and reduce the obstruction to blood, to intervene cardiac valve surgery
In, it is possible to prevente effectively from the use of temporary pacemaker, so as to improve operating difficulty and complexity.
