Description
Technical field
Medical instruments field of the present invention particularly relates to a kind of Tricuspid valve edge-to-edge jaw device that can implant through conduit.
Background technology
Cardiovascular disease is the No.1 killer of present harm humans health, and wherein valvular heart disease has occupied very large proportion.Common valve disease comprises that the function and structure of single or multiple valve structures is unusual.The past people are higher to the degree of concern of aortic valve and mitral valve disease, and new Therapeutic Method emerges in an endless stream, and effectively given treatment to a large amount of valve patients.Along with people's deepening continuously to valvular heart disease understanding, the Tricuspid valve disease more and more receives publicity, and the heart failure problem that especially tricuspid regurgitation is caused is because treatment means is very limited, and the effect extreme difference is becoming the hot issue of present valvular heart disease research field.
The Tricuspid valve anatomical structure comprises lobe ring, lobe leaf, chordae tendineae and papillary muscles.The lobe leaf is comprised of front lobe, back lobe, septal leaflet, and the lobe ring is the attachment margin of three lobe leaves.Minale is inhomogeneous, the most obvious in some position expansion of forward and backward lobe ring in the expansion of nineteen ninety discovery feature tricuspid regurgitation patient's tricuspid annulus, and the septal leaflet cyclic group is originally constant.But after have domestic scholars statistics back lobe ring compared with normal to enlarge 80%, front lobe ring can enlarge 40%, the septal leaflet ring only can enlarge 10% because of the restriction that is subjected to interventricular septum
[18]Thus, the tricuspid valvular insufficiency mainly has obvious expansion at forward and backward lobe ring, in fact only forward and backward valve annulus is formed, and does not process the septal leaflet ring, also is a kind of strategy.The selectivity Tri An that Minale proposes is namely based on such consideration, this operation is exactly in front posterior valve leaflet and front and back lobe boundary the lobe blade root to be cut, select to enlarge the most significant lobe ring portion position and carry out the folded seam contracting, at last remaining lobe ring and lobe leaf are sewed up continuously, finished the reconstruction of dissection and function.Therefore think, the forward and backward lobe leaf of Tricuspid valve is carried out suitable intervention, equally also can reach the purpose of correcting tricuspid incompetence.
At present, the processing of tricuspid incompetence is still take Tri An as main, and the tricuspid valve replacement not only causes conduction block easily, and long-term effect is poor, and mechanical prosthetic valve also relates to the inconveniences such as Anticoagulation, so use clinically less.With the mitral valve incompetence Therapeutic Method be not both, tricuspid valvular insufficiency Therapeutic Method is more, but at present, also is acknowledged as optimal method without any a kind of method.The interventional therapy for valve disease technology that occurs is in recent years obtaining people's common concern, can use the method treatment tricuspid valvular insufficiency of Wicresoft, it is a brand-new problem, because the interventional therapy wound is little, healing is fast, patient is acceptant, can the characteristics such as intervene in early days in pathological changes, determines that this technology will be a kind of revolutionary Therapeutic Method.
The Wicresoft that carries out the Tricuspid valve edge-to-edge gets involved repairs, need to implant a kind of jaw device, this device designing requirement need to be avoided the impact on valvular function on the one hand, on the other hand, need to select to have the material of good biocompatibility, can reach in the short period of time endothelialization, avoid the formation of thrombosis.
Along with the maturation of frontal lobe and the posterior lobe of mitral valve being carried out edge-to-edge's recovery technique through conduit, design the jaw device that meets anterior tricuspid leaflet, posterior lobe anatomical features, carry out through the forward and backward leaf reparation of conduit tricuspid valve, make a hole lobe, become two hole lobes, correct the tricuspid valvular regurgitation, be finish feasible, can imagine that effect is desirable, the more important thing is by less invasive techniques and just can intervene at the early stage of pathological changes generation, the progress of control pathological changes.Particularly along with the progress of material, to develop the Ultimum Ti jaw device and finish feasiblely, operative installations can significantly reduce the generation of this technology complication.
Summary of the invention
Technical problem to be solved by this invention provides a kind of Tricuspid valve edge-to-edge jaw device that can implant through conduit, simple in structure, biocompatibility and spike performance are good, and mechanical support power is good, good compliance and shape memory are arranged, and use procedure is less to the wound that patient causes.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Tricuspid valve edge-to-edge jaw device that can implant through conduit is provided, comprise rotation forward operation bar, connect push rod, body supports threaded rod and Nitinol dished wheel, described rotation forward operation bar is enclosed within the outside that connects push rod, described connection push rod is connected with the body supports threaded rod of below by the straight pin of its lower end, the outside of described body supports threaded rod has been evenly arranged the spiral type projection, the outside of described body supports threaded rod is socketed with rotary support mechanism, the connecting rod that stretch out described rotary support mechanism both sides is connected with the middle hypomere of needle plate on the lobe that lateral symmetry is arranged respectively, and the lower end of needle plate is connected with body supports threaded rod lower end on the described lobe.Both sides, the junction symmetry of needle plate and body supports threaded rod is connected and installed and outwardly directed lobe lower shoe on the described lobe, and the middle part of described lobe lower shoe clamps and is fixed with oval-shaped Nitinol dished wheel.
The lower end intermediate arrangement of described rotation forward operation bar has a circular projection, and the upper end has a dovetail breach in the middle of the described rotary support mechanism, and the size of described dovetail breach and circular projection match.
