Abstract
The utility model belong to the field of medical component, in particular to an artificial values of heart forming ring and holding ring apparatus which are used for cardiac surgery. An inner core of the value ring is made of medical silicon rubber belt. Polyester fiber wraps the value ring. The outer coating of the value ring is a ring belt made of medical knitting plush polyester fiber. The value ring and the holding ring apparatus are used with mutual coordination to maintain the situation of the configuration of the normal values ring of heart. The convenient and reliable stitching operation of the utility model is able to cause valve pathological change patient to retain own cardiac valves, and replaces changing value operation. After operation, health restores rapidly and lifetime anticoagulation is not needed, so that the medical expense is decreased and the quality of life for patients is improved.
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.
