Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of used forming ring of artificial heart valve forming art that is used for.
Background technology
Utilize valve forming ring to carry out the valve forming operation early than the seventies in last century.Valvoplasty development in recent years rapidly, and is ripe day by day from the theory to the clinical practice.Valve forming ring is used by wide model as the sophisticated product of a class.Present valve forming ring can be divided into two classes substantially: hard ring and soft ring.The hard ring mainly is that ring core is a metal matter core, and is though this hard ring has good correcting action to valve, relatively poor with the compliance of cardiac muscle.Application number is 00103774.9 to disclose a kind of artificial body for valvoplasty, and the core silk of this prosthese is in plane of a loop tool plasticity preferably, and the core silk adopts alloy, though this ring body is improved on plasticity, it still differs far away with cardiac muscle the complying with when contracting of relaxing.Soft ring inner core mainly adopts nonmetallic medical macromolecular materials, and its three-dimensional flexibility and compliance are better, but difficulty has strong, persistent support and shaping effect when being used to rescue the lobe ring of gross distortion.As China Patent No. is 02259200.8,03242355.1 all to be to adopt silicone rubber to make inner core.Often identification is unclear down because of the X line to these soft inner cores simultaneously, influences the postoperative check.
Summary of the invention
Technical problem to be solved by this invention is by changing structure and composition, realize a kind ofly both having had certain rigid to guarantee rescuing to pathological changes or distortion lobe ring, can satisfy its three-dimensional flexibility again, thereby satisfy the myocardial compliance after rescuing, so that it is recovered to greatest extent.Simultaneously, the artificial heart valve forming ring that can develop is convenient to the check of post-operative recovery degree more.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of artificial heart valve forming ring, be a sealing or a partially enclosed ring body, the ring body cross section is circular or oval, the ring body outermost layer is the medical implantable polyester textile with biocompatibility, and described medical implantable polyester textile is coated on outside the stay pipe, and stay pipe is built-in with inner core, have the gap between inner core and the stay pipe, described stay pipe is medical implantable intravital macromolecular material.
Improvement as this technical scheme, the external diameter of described stay pipe is 1.8mm～2.5mm, the wall thickness of stay pipe is 0.3mm～1.2mm, the cross section of described inner core is rectangle or square structure, long is 0.6mm～1.8mm, wide is 0.4mm～1.6mm, and the material of described inner core is medical implantable intravital macromolecular material; Described inner core blending has 10%～60% inorganic material that can develop under X ray; Described medical implantable intravital macromolecular material is medical silicone tube, medical polyethylene, polypropylene, poly-tetrafluoro or polyurethane material.
Another kind as this technical scheme improves, the external diameter of described stay pipe is 1.8mm～2.5mm, and the wall thickness of stay pipe is 0.3mm～1.2mm, and described inner core is medical implantable metal spring, cross section metal is circular, and the external diameter of described metal spring is 0.6～2.2mm.
For further improvement in the technical proposal, blending has 10%～60% inorganic material that can develop in the described stay pipe under X ray; The described inorganic material of developing is hydroxyapatite, barium salt or calcium salt; Have two or more labellings on the described medical implantable polyester textile, wherein two distances that the labelling spacing is a human heart lobe ring left and right sides fibrous triangle; Described medical implantable polyester textile wall thickness is 0.2～0.5mm.
The beneficial effect that the present invention can produce is:
(1) ring body has stay pipe, and pipe contains the inner core of material of the same race, and stay pipe and the combination of inner core have realized to greatest extent with to rescue the back myocardial compliance consistent.Improved the performance of ring body and myocardium synchronization telescope, made forming effect better, and shortened patient's post-operative recovery time, to reduce complication.
(2) mixed the inorganic material that to develop in inner core and the stay pipe, made its clear debating under the X line, more convenient postoperative check.
(3) marking with the distance between the real marking-cardiac valve annulus left and right sides fibrous triangle at human dissection position on the ring body outer surface, can more accurate judgement and the specification of selected valve forming ring, it is just right to make it the rectifying effect that produced.This is avoided complication most important to postoperative.If rescue the valvular stenosis that excessively may cause to a certain degree, if rescue the not enough valvular insufficiency that still can retain part.
(4) there is the gap between ring body stay pipe and inner core, can make it in myocardial contraction and diastole campaign, inner core and stay pipe produce relative displacement, thereby the wriggling performance of adjusting ring body is consistent itself and myocardial compliance, satisfies its three-dimensional flexibility to greatest extent.In addition, the existence in this gap makes down pin easier, has improved the sticking of needle that the patient occurs when sewing up forming ring effectively.

The specific embodiment
Embodiment one
Consult Fig. 1, Fig. 2 schematic perspective view and sectional view for the artificial cardiac valve forming ring of the present invention.The medical macromolecular materials that the artificial cardiac valve forming ring of the present invention has been selected implantable body are as stay pipe 1, and the external diameter of stay pipe 1 is 1.8～2.5mm, and wall thickness is 0.3～1.2mm.Inner core 2 places in the stay pipe 1, can select polyethylene or other medical macromolecular materials for use, and has mixed 10%～60% the inorganic material of developing, and as hydroxyapatite, barium sulfate etc., inner core is also selected the material of stay pipe same material for use.The cross sectional shape of inner core is a rectangle, length is 0.6～1.8mm, wide is 0.4～1.6mm, and there are certain clearance in 1 of inner core 2 and stay pipe, so that the compliance of whole ring body is better, the compliance of so-called stay pipe and inner core and cardiac muscle better is meant, when selecting stay pipe and inner core material for use and determining their size, stay pipe is enclosed within outside the inner core, by the size of adjusting the inner core and the gap of stay pipe, the material of the two and adapting with it, simulate combination ring body with the easypro close three-dimensional flexibility that contracts of cardiac muscular tissue.
The forming ring outermost layer coats nontoxic, non-irritating active medical fabric 3 commonly used usually, and wall thickness is 0.2～0.5mm.On medical fibre fabric 3, have three labellings 4,5,6, wherein the distance between labelling 4 and the labelling 5 is the distance of human heart lobe ring left and right sides fibrous triangle, the model of general this forming ring is also decided by this distance, the distance that is human heart lobe ring left and right sides fibrous triangle as No. 27 forming rings is 27mm, in the operation implementation process, the distance of elder generation's consumption ring device bigness scale human heart lobe ring left and right sides fibrous triangle, after determining, distance can find the forming ring of corresponding size rapidly, with the labelling on the forming ring 4,5 alignment body cardiac valve annulus left and right sides fibrous triangles, can improve the accuracy of operation greatly, save operating time.
The plastic operation of this forming ring should be arranged, in the process of rehabilitation after surgery,, can observe patient's surgical effect easily owing to can under X or CT-X, develop.
Embodiment two
In embodiment one, its inner core is also replaceable to be the medical titanium alloy metal spring of implantable body, and its external diameter is 0.6～2.2mm, other structure and structure consistent (as Fig. 3) among the embodiment one.
