Description
Technical field
The invention belongs to artificial heart field, specially refer to artificial heart pump in artificial heart pump's implant surgery retainer ring andInstallation method.
Background technology
(heart failure) in heart failure is a kind of disease of serious threat human health. For the most effective methods for the treatment of of advanced heart failure beHeart transplant and artificial heart are auxiliary, and because heart transplant can not meet the needs that heart failure is treated far away, market is to artificial heart pumpDemand constantly increase, thereby its market prospects are very good. Use artificial heart pump, first need to carry out artificial heart pumpImplant surgery. Implanting in complete process, artificial heart pump need to be fixed on to aorta vessel inside, traditional method isAfter artificial heart pump implants, adopt the mode of stitching or anchor line (string) that artificial heart pump is fixed, prevent that artificial heart pump is in activeMotion in arteries and veins. On the one hand, the fixed form of stitching or anchor line (string) has spent the more time, and in sewing process, operation is lostBe easy to occur by mistake; On the other hand, suture is too thin, and in using for a long time, it may cut bad blood vessel, thereby has influence onPatient health.
Retainer ring is widely used for domestic and international industry-by-industry. Patent CN203081925U has designed straight dress divergence type retainer ring, fixingEncircle separablely, be applicable to the fixing of machine-building axis, this invention is metal material, and retainer ring directly contacts with fixation,Be fixed by bolt; Patent CN203081930U designed straight dress open-type retainer ring, is applicable to machine-building axisFixing, this invention is metal material, and retainer ring directly contacts with fixation, is fixed by bolt, and retainer ring is overstepping one's boundsRelease design; Patent CN202637214U has designed the retainer ring fixing for the finger after fracturing, and this invention is for external handWhat refer to is fixing, and retainer ring is non-divergence type design, is fixed by encircling outer puller strap; Patent CN203001098U has designedThe anti-dislocation angle of anterior plate fixation screw retainer ring, is applicable to orthopaedics operation, and retainer ring is non-divergence type design, fixingRing directly contacts with fixation; Mode by bolt is fixed. It is more tighter that artificial heart pump fixing has by contrastThe requirement of lattice: retainer ring can not be to the interference in magnetic field; Retainer ring directly contacts with sustainer, has high biocompatibility requirement;Retainer ring protection blood vessel is not pushed by hard ring body; Retainer ring will be installed and used quickly and easily, avoids the operation of complicated and time consumption;Retainer ring will be guaranteed can not have space between blood vessel and artificial heart pump after using; Reduce the sky of retainer ring in thoracic cavity as far as possibleBetween take. These problems are to solve above, and current existing design can not realize.
Summary of the invention
In order to improve the technology that existing artificial heart pump is fixing, the invention provides one fast artificial heart pump's retainer ring andUsing method:
A kind of rapid artificial heart pump retainer ring, becomes the ring gear of annulus and lock ring to form by zoarium, and described ring gear is semicircular ring, andAnd the arc-shaped rack that semicircular ring two ends have respectively continuation to stretch out along circular arc, this tooth bar is sawtooth, before this sawtooth, is gentle slope, is afterwardsAbrupt slope; Described lock ring is semicircular ring, and it is inner for inserting the cavity of described tooth bar, and cavity wall is provided with described sawtooth and coordinatesTeeth groove; Be laid with in the inner side of described ring gear and lock ring cambered surface the vascular protection band that flexible material forms; Described ring gear and lock ringAll adopt flexible biological compatibility material to make. When use, artificial heart pump is placed in blood vessel, and the lock ring of semicircular ring is buckled in to peopleOn the blood vessel of work heart pump head, then the ring gear of semicircular ring is buckled on second half of blood vessel, two toothed rack are inserted lock rings simultaneouslyCavity, until two semicircles are merged into a circle, then adopt to use the same method at artificial heart afterbody blood vessel place and is fixed,Artificial heart pump and blood vessel fixedly complete.
The structure of utilizing a kind of rapid artificial heart pump retainer ring of the present invention to adopt ring gear and lock ring to interlock, plants artificial heart pumpEnter in operation, artificial heart pump is placed in the blood vessel of aorta ascendens, two groups of ring gears are buckled in respectively to artificial heart pump mutually with lock ringBlood vessel outside, two ends place, has fixed artificial heart pump fast. These apparatus and method have shortened artificial heart pump when fixing widelyBetween, reduce operation risk; In addition compare suture, retainer ring can increase the active area to blood vessel wall, has reduced pressureProtected blood vessel not hurt by force; The vascular protection band of retainer ring inner side can be protected blood vessel on the one hand, on the other hand, fixingWhen ring extruding vascular protection band, flexible material deformation and be full of retainer ring and blood vessel between space, active force acts on more equablyOn blood vessel, make retainer ring fix better artificial heart pump, eliminate the space that may exist between pump and blood vessel. Finally, GuThe non-metallic material of fixed ring, has got rid of the interference that may cause magnetic field in variation magnetic field.

Detailed description of the invention
Below in conjunction with accompanying drawing, of the present invention and using method are described in further details.
One is artificial heart pump's retainer ring fast, and main body is ring gear 2 and lock ring 3, adopts nonmetal biocompatible materials,Ring gear 2 and lock ring 3, according to actual conditions designs different size, mainly comprise Φ 22, Φ 24, Φ 26(mm) etc. different inner diameters;Wherein there is respectively the tooth bar 4 stretching out at ring gear 2 two ends places, and the tooth in tooth bar 4 is front slow rear steep sawtooth, and lock ring 3 inside are emptyChamber 5, cavity 5 inwalls have teeth groove 6, and teeth groove 6 can fit like a glove with tooth bar 4, and tooth bar 4 and teeth groove 6 also adopt nonmetal lifeThing compatibility material; Ring gear 2 and lock ring 3 inner sides are covered and are formed vascular protection band 7 by flexible non-metallic biocompatible materials,As medical grade silicon rubber, to tissue nonirritant, nontoxicity, few without allergic reaction, body rejection; Have goodPhysicochemical property, with body fluid and organize in contact process and can keep its original elasticity and pliability, be not degraded, be a kind ofThe material of quite stable.
On operation is implemented, first cut off an otch at aorta ascendens 10 places, and vise incision blood flow with haemostatic clamp, by peopleWork heart pump 9 is inserted aorta vessel inside, and guarantees correct (artificial heart pump's afterbody sensing aorta petal of pump placing directionDirection), sew up afterwards sustainer otch. At artificial heart pump's head blood vessel place, choose artificial heart pump's retainer ring of suitable dimension1, lock ring 3 is buckled on blood vessel 8, then ring gear 2 is buckled in to the plane of symmetry position of this place with respect to blood vessel, simultaneously by two tooth bars4 insert cavity 5, promote the extremely deep-seated of this annulus tooth bar and put, and two semicircular ring merge, and have completed the fixing of artificial heart head,Then adopt to use the same method at artificial heart afterbody blood vessel place and be fixed. Artificial heart pump fixedly completes.
In artificial heart pump's implant surgery, pump need to be implanted in sustainer, thereby the mode of formation and sustainer series connection is logicalCross self to rotate and extract ventricle inner blood, in conjunction with idioventricular contraction, improve the function of left ventricle pump blood.
