Abstract
The invention discloses a positioning device for an artificial heart valve, wherein the device belongs to the technical field of medical instruments (appliances). The positioning device comprises an outer pipe, a positioning frame, an inner pipe and an operation handle, wherein the inner pipe is movably inlaid in the outer pipe; the positioning frame is fixed on the front end of the inner pipe, and the operation handle controls the inner pipe to move in the outer pipe. The device is characterized in that a developing ring is disposed on the end part of the outer pipe; the positioning frame is a telescopic self-springing support; the positioning frame is composed of multiple positioning rods; the positioning frame is fixed on the front end of the inner tube; the operation handle pushes the inner pipe, so the positioning frame can be pushed out and released by self-springing; and an artificial heart valve system is conveyed to a lesion site by the cavity of the inner pipe. According to the invention, the device has the advantages that accuracy of heart valve release is increased; developing ring positioning is accurate and rapid; the position of the valve system could be determined reliably; damage and risks countered by a patient due to multiple times of developing (and rapid pacing) could be reduced, etc.
Description
Technical field
The present invention relates to Medical Instruments（Apparatus）A kind of Cardiac valve prosthesiss positioner of technical field.
Background technology
Valve disorder has become one of common cardiovascular disease, the heart valve of human body（heart valve）It is the one-way cock system of a blood flow, heart valve system includes the aortic valve of the left heart and the valve of pulmonary trunk and Tricuspid valve of Bicuspid valve and the right heart, if there is dysfunction in heart valve, the normal blood-pumping function of heart will be affected, the health of infringement heart itself and whole body other organs, more entail dangers to life when serious.Pathological changes or other reasonses lose the heart valve of function, by surgically repairing or can replace, and modus operandi has a series of high risk factor to patient, such as infection, apoplexy, renal failure and other severe complications related to extracorporeal circulation.In recent years, the operation method that heart valve is replaced by way of the intervention of minimally invasive or percutaneous increasingly obtains the accreditation of clinical practice, is revolutionary innovation in a kind of heart valve disease treatment field.
The implanted prosthetics of current Jing conduit cardiac lobes all suffer from greatly a difficulty, i.e. location difficulty, and this carrys out very big risk to the implantation belt of lobe.Such as：In release to continue visible annulus position, multiple radiography is generally required, make patient face the risk of damage of contrast agent；To reduce disturbance when lobe discharges, often apply rapid pacing, also make patient's risk；As fruit lobe off-position is undesirable, the non-normal work of lobe or displaced more can cause greatly to damage even life danger to patient.So, it is ensured that the success being accurately positioned to performing the operation when Jing conduit cardiacs lobe is implanted into is significant.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art, propose a kind of positioner of new Jing conduit cardiac lobes, the problems referred to above can be efficiently solved, is that Jing conduit cardiac lobes are successfully implanted into offer reliable guarantee, hence it is evident that reduce related clinical risk.
The purpose of the present invention is 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 is movably embedded in outer tube, and 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：The outer tube end is provided with developing ring, locating rack is contractile eject support, locating rack is made up of some locating rods, locating rack is fixed on the front end of inner tube, operation handle promotes inner tube locating rack to be released from bullet release, artificial heart valve system is transported to lesion by inner tube cavity, and inner tube can be movable relatively with outer tube, to discharge and reclaim locating rack；Jing conduit cardiac lobe systems can be with respect to movement of inner pipe.
Further restriction is done to above-mentioned technical proposal, described locating rack is made up of superelastic NiTi alloy material.
Further restriction is done to above-mentioned technical proposal, the locating rack is made up of 3 to 9 locating rods, the stretching angle after locating rod release is identical.
Further restriction is done to above-mentioned technical proposal, inner tube is with the connection of locating rack using bonding, welding or removable mechanical attachment.
The present invention has the advantages that compared with prior art：
1. the cardiac valve of Jing artificial heart valvees positioner implantation improves the accuracy of cardiac valve release.
2. the developing ring accurate positioning of outer tube end, quick, reliably determines the position of lobe system.
3. reducing multiple radiography makes patient face the risk of damage of contrast agent.
4. rapid pacing need not be implemented, relevant risk is greatly reduced.

13. specific embodiments
Present disclosure is described further below in conjunction with the accompanying drawings：
It as shown is in artificial heart valve positioner schematic diagram, including outer tube 1, inner tube 2, locating rack 3, cardiac valve 4, cardiac valve（Outward）Pipe 5, cardiac valve front end 6,（Aorta）Lobe 7, ventricle 8 and ultrahard guide wire 9.
Artificial heart valve positioner Jing aortas reach aortic sinus position, and the controllable relative motion between inner tube and outer tube of operation handle discharges and reclaim locating rack by operation handle；Artificial heart valve system Jing artificial heart valve positioner inner tube reaches aortic sinus position.
Artificial heart valve system and this alignment system can be assembled together in vitro, while sending into aorta；Also can first send into alignment system, it is to be positioned after the completion of, then the inner tube of Jing this alignment system sends into artificial heart valve system and completes implantation.
Jing aortas approach reaches aortic sinus position, and radiography determines that distal end is located at active lobe top, starts to discharge locating rack, pushes ahead inner tube so as to front push away the hole bottom around locating rack arrival aortic valve.The position of lobe system now can accurately, be quickly and reliably determined according to the locating rack of development, and start the release process of lobe, after lobe release to a certain degree, withdraw locating rack, continue to complete the release process of lobe, process is discharged on whole lobe without the need for carrying out contrast agent again, without enforcement rapid pacing.Whole system is finally withdrawn from the implantation process of the artificial heart valve for completing whole in vitro.
Fig. 2 ~ Fig. 7 shows artificial heart valve positioner implantation step.
