Description
Technical field
This utility model relates to the device that animal disease model is made, especially a kind of producing device for large animal chamber valvular regurgitation disease model.
Background technology
Valvular regurgitation is a kind of clinical common cardiac disorder, wherein common clinically with mitral incompetence (mitral regurgitation, MR), it is reported, the ultrasonic examination mild MR can be up to 19% at normal population, and moderate MR or severe MR are respectively 1.9% and 0.2%.Mitral incompetence makes left atrium and left ventricular diastolic load increase the weight of, and can cause that pulmonary vein and pulmonary capillary pressure raise, and cause vasodilation and congestion then; The left ventricular diastolic volume load increases simultaneously, and left ventricle enlarges, if acute serious mitral incompetence can make left atrium and pulmonary vein pressure sharply rise, causes acute lung edema.Chronic MR harm is also large, and diagnosis and treatment, by easy atrial fibrillation, also often cause pulmonary venous pleonaemia and body circumfusion to hang down inferior left heart failure not in time, and pulmonary hypertension and whole heart failure can appear in late period, directly life-threatening.Just because of this, the clinical importance of MR is subject to increasing attention, research about mechanism, Pathophysiology characteristics and the diagnosis and treatment new technique of MR is extensively carried out, the video diagnostic technology that some are new, especially the genesis change mechanism of atrial fibrillation, in the fields such as the medical and surgical treatment means evaluation of heart failure, study hotspot all needs a large animal model of good stable MR.
Setting up at present this class animal model mainly reaches and affects the valve tight closure by the primary structure that destroys, changes or affect the Bicuspid valve devices such as lobe leaf, chordae tendineae, papillary muscles, lobe ring, left atrium or left ventricle, thereby cause blood from the anti-atrium that flows to of ventricle, reach the purpose of making the large animal model of chamber valvular regurgitation.Wherein by damage lobe leaf and chordae tendineae, the most easily realize.Make by this method animal valvular regurgitation model two approach are arranged: open breast and do not open breast.The method of traditional making mitral incompetence model of opening breast generally need be cut off and destroy valve or chordae tendineae through the left auricle operation by extracorporeal circulation under direct-view, and the model that these class methods are made is homogeneous comparatively, definite, but expense is higher, and wound is larger; Also have and see the die-manufacturing method through the apex position, Bicuspid valve damaged under a kind of beating heart, this method similar technology difficulty is large, and wound is still larger.The method master who does not open breast refers to by the conduit interventional technique under the guidance of X-ray, destroy valve or chordae tendineae by special nipper, this method generally need to be by the anti-size that flows of ultrasonic judgement, the nipper special due to needs operates under X-ray, specification requirement is higher, difficulty is large, cost is high, long also poor apart from the controllability of operation model, often or pull too heavy, mortality rate is very high, pull lighter, the inadequate homogeneous of model, operate comparatively loaded down with trivial details, it is poor that model can repeat, often need injection of contrast medium repeatedly, the consumptive material costliness, the modelling personnel need be exposed under x-ray, make the practical application of this method be subject to certain limitation, the foundation of mitral incompetence model once had been trapped in bottleneck stage.
From the above mentioned, the anti-fluid disease model of existing chamber valve mold making technology exists following not enough: the traditional surgery wound is larger, the animal easy infection, and mortality of animals is high, costly; Get involved the method for not opening breast under x-ray and need special molding instrument, operate loaded down with trivial details, technical difficulty large, be difficult for grasping anti-uninterrupted, modelling repeatable poor, mortality rate is high, the model homogeneity is poor, often need injection of contrast medium repeatedly, the consumptive material costliness, modelling personnel and animal all need to be exposed to heavy dose of roentgen radiation x, make its scope of application limited.
