Abstract
The invention relates to a detachable two-bladed artificial mechanical cardiac valve, which consists of a circular valve support and two symmetrical semilunar valve blades, wherein the circular valve support is divided into two symmetrical semilunar valve supports; each valve support has a pair of shaft journals and chock blocks; the upper part and the lower part of each of the two symmetrical semilunar valve blades are respectively provided with two valve axes; the two pairs of valve axes are corresponding to the two pairs of shaft journals and can be conveniently inserted in and pulled out; and the two pairs of chock blocks respectively control the maximum opening angle of the two symmetrical semilunar valve blades. The two-bladed artificial mechanical cardiac valve is detachable and can conveniently change the geometrical shapes of certain parts of the mechanical cardiac valve according to design requirements while keeping other design structures unchanged, thereby ensuring lower cost and research data with more comparability.
Description
Technical field
The present invention relates to a kind of a kind of artificial mechanical heart valve that the present invention relates to, particularly a kind of detachable double-leaf artificial mechanism heart valves.
Background technology
The displacement of mechanical heart valve is effective treatment means of valvular heart disease patient, has carried out clinically nearly 50 years, probably has every year 200000 people to accept artificial valvular implant surgery.The bilobate mechanical heart valve is most widely used clinically as the latest generation of mechanical prosthetic valve.For example, the Chinese invention patent description of the CN91100324.X that on August 12nd, 1992 was announced discloses a kind of mechanical bilobed heart valve made of ceramics, this bilobed flap is made up of a lobe frame, two lobe blades, two lobe axles by each lobe blade, be fixed on the lobe frame that has four axle pivots, form and freely rotate.The bilobate mechanical heart valve has good endurance, effective orifice area and reaches plurality of advantages such as hemodynamics function admirable greatly, the bilobate valve of U.S. St.Jude Medical company particularly, in clinical practice and theoretical and experimental study process for many years, all as " goldstandard ".But mechanical prosthetic valve is normal thromboembolism and the haemolysis complication of taking place after implant surgery, need the patient to take anticoagulation medicine throughout the year, valve is closed the high-speed jet of formation and cavity the damage of lobe body also is no lack of report, and therefore, real ideal mechanical heart valve still remains people and continues research.Traditional bilobate mechanical heart valve, lobe frame and lobe leaf can not be split, and researcheres during to the influencing of every evaluation index, can only adopt the valve of each producer and/or different model in the different structure designs of valve relatively, cost is than higher, and the comparability of experimental result is relatively poor.
Summary of the invention
The present invention be directed to existing bilobate mechanical valve prosthesis can not be split, the cost height, the problem of the comparability difference of experimental result, a kind of detachable double-leaf artificial mechanism heart valves has been proposed, this valve can be in experimental study, according to the needs of goal in research, change the structural design of mechanical valve prosthesis more conveniently, targetedly, to save cost and time.
Technical scheme of the present invention is: a kind of detachable double-leaf artificial mechanism heart valves, form by circular lobe frame and two symmetrical semilune lobe leaves, described circular lobe frame is divided into two symmetric semicircle lobe framves, and a countershaft pivot and each a pair of block are respectively arranged on each lobe frame; Described two symmetrical semilune lobe leaves respectively have two lobe axles up and down; Two pairs of corresponding two countershaft pivots of lobe axle can insert and extract easily; Two pairs of blocks are controlled the maximum open angle of two symmetrical semilune lobe leaves respectively.
The apical position of described two pairs of blocks is on the interior diameter contour of described circular lobe frame.
A kind of device that detachable double-leaf artificial mechanism heart valves is installed, comprise that diameter is respectively the overall diameter of described circular lobe frame and two cylindrical cavities of size of interior diameter, comprise that also compacting part is the shell cylinder, place described big column cavity inner chamber also to be sealed and matched with it.
Beneficial effect of the present invention is: detachable double-leaf artificial mechanism heart valves of the present invention can be according to designing requirement, change the geometry of some part of mechanical heart valve easily, and it is constant to keep other project organizations, makes that cost reduces, data has more comparability.

The specific embodiment
As Fig. 1, shown in 2, detachable double-leaf artificial mechanism heart valves is by two symmetric semicircle lobe framves 1 as Fig. 1,2 and as two symmetric lobe leaves 15 of Fig. 2,16 form, one countershaft pivot 3 is respectively arranged on each lobe frame, 5 and 4,6 and each a pair of block 7,8 and 9,10, lobe leaf 15,16 two lobe axles 11 up and down by it, 12 and 13,14 insert axle pivot 3 respectively, 4,5, in 6, two lobe framves 1,2 consistencies from top to bottom coincide and are circular lobe frame, clamp two lobe framves 1 with finger, 2, make it to become and comprise lobe leaf 15 free to rotate, a complete heart valve of 16.
A kind of as shown in Figure 3 device that detachable double-leaf artificial mechanism heart valves is installed, device is by circular lobe frame 1, two cylindrical cavities 17 of 2 the overall diameter and the size of interior diameter, 18 form, the bilobate mechanical heart valve that assembles is slowly pushed tube chamber 17 foremost, the intersection that is tube chamber 17 and tube chamber 18 is fixed, tube chamber 17 and lobe frame 1,2 overall diameter is sealed and matched, two pairs of blocks 7,8 and 9,10 its apical positions are at lobe frame 1, on 2 the interior diameter contour, with lobe leaf 15,16 enter in the interior cylindrical cavity 18, at lobe frame 1,2 rear portion, place a shell clamp cylinders body 19 that is sealed and matched as shown in Figure 4 in the cavity 17, withstand the clamping valve.
Detachable double-leaf artificial mechanism heart valves is contained in the physiological pulse laboratory table, and two lobe leaves 15,16 can freely rotate, and are involutory mutually when closing, and seal channel of blood flow with the inner surface of interior cylindrical cavity 18; Two lobe leaves 15,16 are run into and are stopped behind the block 7,8,9,10 opening in the opening process, form three channel of blood flow between the lobe leaf 15,16 and between the inner surface of they and interior cylindrical cavity 18.
