Abstract
本实用新型属医疗用品领域，具体涉及一种心脏外科用的人造心脏瓣成型环，和其应用的持环器。本实用新型瓣环由医用硅橡胶带制作内芯，外包裹涤纶织物，外层由医用针织毛绒型涤纶制成环带，本瓣环需与持环器配合使用，以使其能保持正常心脏瓣环外形的状态，本实用新型手术缝合方便、可靠，可使瓣膜病变患者保留自身的心脏瓣膜替代换瓣手术。术后健康恢复迅速，且无需终身抗凝，降低了医疗费用，提高患者的生活质量。
The utility model belongs to the field of medical supplies, and in particular relates to an artificial heart valve forming ring for cardiac surgery and a ring holder applied thereto. The valve ring of the utility model is made of medical silicon rubber belt as the inner core, wrapped with polyester fabric, and the outer layer is made of medical knitted plush polyester ring belt. The valve ring needs to be used in conjunction with the ring holder to keep it normal The state of the shape of the heart valve ring, the utility model is convenient and reliable for surgical suturing, and can enable patients with valvular disease to retain their own heart valves to replace valve replacement operations. Postoperative health recovery is rapid, and there is no need for life-long anticoagulation, which reduces medical expenses and improves the quality of life of patients.
Description
Technical field
This utility model belongs to field of medical products, and what be specifically related to artificial heart's lobe molding ring that a kind of department of cardiac surgery uses and its application holds the ring device.
Background technology
The seventies, external the first prosthetic valve ring carried out cardiac valve molding operation.The eighties, the cardiac valve urethroptasty obtained develop rapidly in international department of cardiac surgery field, and heart prosthetic valve ring product is also updated.During at present imported product is used at home because of it costs an arm and a leg, with the income level incompatibility of China's most of patients.So far still there is not homemade prosthetic valve ring.
Summary of the invention
The purpose of this utility model provides a kind of artificial heart valve ring, be used for the annuloplasty band operation, make a part of valve pathological changes patient can keep the cardiac valve of self, through the annuloplasty band postoperative, the lobe ring of expansion is restored to the original state, correct valvular insufficiency, can stop the expansion of postoperative lobe ring again, also can reduce the tension force that bear at the suture place on lobe ring and the lobe leaf.Therefore the application of artificial heart valve ring, the cardiac valve that can make a part of valve pathological changes patient can keep self substitutes heart valve replacement surgery.Postoperative health is recovered rapidly, and need not lifelong anticoagulant, improves patient's quality of life.
Introduce planform of the present utility model in conjunction with the accompanying drawings:
This utility model lobe ring is made for the arc of a soft bending, and this lobe ring is by forming with the lower part:
Inner core 1 adopts the medical grade silicon rubber band to make, and its thickness can be the 0.9-1.3 millimeter, and preferred thickness can be the 1.1-1.3 millimeter, and optimum thickness is 1.2 millimeters, and its width can be the 1.5-2.2 millimeter, and optimum width is 2.0 millimeters.It can develop down by the X line.The outer 2 parcel dacrons of inner core, outer be fixed on to sew up again on the medical stitched pile type of a slice terylene limit with medical suture form one section softness and the terylene endless belt 3 of flexible is this utility model lobe cyclic group plinth endless belt.Lobe leaf joint portion establishes boundary mark line 4 before and after the two ends of terylene endless belt.
Because of the lobe ring itself is soft, need during use and hold ring device 5 and cooperate, the lobe ring is installed in holds on the ring device periphery so that it can keep the state of normal heart lobe ring profile, originally hold the ring device and adopt medical plastic to make, the camber line of profile is according to the anatomical features and the design of dynamic function characteristics of normal heart.It is 6 curved that back lobe encircles, and relaxing in cardiac cycle contracts changes obviously, and this camber line part side is provided with a special-shaped groove, and aperture 7 is arranged in the groove, and suture is fixed on the lobe endless belt herein, is convenient to operation technique.And preceding lobe ring 8 is short more straight, makes a umbilicate type, and its both sides are provided with solid ring through wires hole 9, and the easypro variation of contracting in cardiac cycle of preceding lobe ring is less, and the prosthetic valve ring can not sew up, and brings convenience to operation.Originally aperture and the groove held on the ring device are used for wearing suture, and fixedly the prosthetic valve ring cuts off suture with leaving in the operation process, make the lobe ring be easy to separate, and shift out.Originally hold on the ring device and also be provided with screw or bayonet socket 10, be convenient to handle 11 loading and unloading, make operation technique more random.Originally hold the transverse diameter of ring device and can make the 18-38 millimeter according to the operation needs.
This utility model can satisfy domestic patient's demand, has reduced high medical expense, and patient as much as possible can both be obtained medical treatment, and through clinic trial, the result shows that this utility model intensity and elasticity are all good, and operation stitching is convenient, reliable.On the other hand, also can save the foreign exchange spending, not only benefit the nation but also favorable to the people, have remarkable economic efficiency and social benefit.
