Description
Technical field
The present invention relates to Medical Instruments（Apparatus）A kind of heart valve prosthesis positioner of technical field.
Background technology
Valve disorder becomes one of common angiocardiopathy, the heart valve of human body（heart valve）It is one
The one-way cock system of a blood flow, heart valve system include aorta petal and bicuspid valve and the pulmonary valve of the right heart and three of the left heart
Cusp, if dysfunction occurs in heart valve, will influence the normal blood-pumping function of heart, other are dirty with whole body in itself for infringement heart
The health of device, more entail dangers to life when serious.Lesion or other reasons lose the heart valve of function, can be by surgical operation side
Formula is repaired or replaced, modus operandi to patient there are a series of high risk factor, such as infection, palsy, kidney failure and other with
The relevant severe complication of extracorporal circulatory system.In recent years, the operation method of heart valve is replaced by way of minimally invasive or percutaneously intervene
The accreditation of clinical practice is increasingly obtained, is revolutionary innovation in a kind of heart valve disease treatment field.
The current implanted prosthetics through conduit cardiac valve all suffers from greatly a difficulty, i.e. location difficulty, this is to valve
Implantation belt carrys out very big risk.Such as：In release to continue visible annulus position, multiple radiography is generally required, makes patient face
Face the risk of damage of contrast agent；To reduce disturbance during valve release, often apply rapid pacing, also make patient's risk；Such as
Fruit lobe releasing position is undesirable, and valve does not work normally or displaced, and greatly damage even life danger can be more caused to patient.
So success of accurate positionin when ensureing to be implanted into through conduit cardiac valve to operation is of great significance.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, it is proposed that a kind of new to determine through conduit cardiac valve
Position device, can efficiently solve the above problem, to be successfully implanted into offer reliable guarantee through conduit cardiac valve, hence it is evident that reduce
Relevant clinical risk.
The purpose of the present invention is what is be achieved through the following technical solutions：
A kind of artificial heart valve positioner, including outer tube, locating rack, inner tube and operation handle, inner tube are movably embedded in
In outer tube, locating rack is fixed on the front end of inner tube, and operation handle control inner tube is moved in outer tube, it is characterised in that：It is described outer
Tube end is equipped with developing ring, and locating rack is contractile eject stent, and locating rack is made of some locating rods, and locating rack is fixed
In the front end of inner tube, operation handle promotes inner tube to discharge locating rack release from bullet, and artificial heart valve system passes through inner tube cavity
Lesion is transported to, inner tube can be movable relatively with outer tube, to discharge and recycle locating rack；Can phase through conduit cardiac valve system
To movement of inner pipe.
Further restriction is done to above-mentioned technical proposal, the locating rack is made of superelastic NiTi alloy material.
Further restriction is done to above-mentioned technical proposal, the locating rack is made of 3 to 9 locating rods, after locating rod release
Stretching angle it is identical.
Further restriction is done to above-mentioned technical proposal, inner tube is with the connection of locating rack using Nian Jie, welding or removable machine
Tool couples.
The present invention has the advantages that compared with prior art：
1. the cardiac valves being implanted into through artificial heart valve positioner improves the accuracy of cardiac valves release.
2. it is the developing ring accurate positioning of outer tube end, quick, reliably determine the position of valve system.
3. reduce the risk of damage that multiple radiography makes patient face contrast agent.
4. rapid pacing need not be implemented, relevant risk is greatly reduced.

13. embodiment
Present disclosure is described further below in conjunction with the accompanying drawings：
As shown be artificial heart valve positioner schematic diagram, including outer tube 1, inner tube 2, locating rack 3, cardiac valves 4,
In cardiac valves（Outside）Pipe 5, cardiac valves front end 6,（Sustainer）Valve 7, ventricle 8 and ultrahard guide wire 9.
Artificial heart valve positioner reaches aortic sinus position through sustainer, and operation handle can control between inner tube and outer tube
Relative motion, is discharged by operation handle and recycles locating rack；Artificial heart valve system is through artificial heart valve positioner inner tube
Reach aortic sinus position.
Artificial heart valve system can be assembled together with this alignment system in vitro, while be sent into sustainer；Also can be first
Alignment system is sent into, after the completion of to be positioned, then the inner tube through this alignment system is sent into artificial heart valve system and completes implantation.
Aortic sinus position is reached through sustainer approach, radiography determines distal end above active valve, starts release positioning
Frame, pushes ahead inner tube so as to the sinus bottom being pushed forward around locating rack arrival aorta petal.At this time can be according to the locating rack of development
Accurately, quickly and reliably determine the position of valve system, and start the release process of valve, after valve release to a certain degree, withdraw positioning
Frame, continues to complete the release process of valve, and process is discharged on whole valve without carrying out contrast agent again, is risen without implementation is quick
Fight.Whole system is finally withdrawn to the implantation process for completing whole artificial heart valve in vitro.
Fig. 2 ~ Fig. 7 shows artificial heart valve positioner implantation step.
