Abstract
The invention provides a bovine pericardial valve forming die, which comprises three hard single valves linearly disposed on a hard substrate at interval. Length of the substrate is equal to inner wall perimeter of human heart aorta. Profiles of the three single valves are the same as that of tricuspid aortic valve. The bovine pericardial valve forming die is convenient in moulding. In application, the bovine pericardial valve forming die is attached to bovine pericardium material, and to-be-replaced valve can be conveniently cut along the three hard single valves. The die has the advantages of simple structure, convenient forming and application, and strong bionic character.
Description
Technical field
The invention belongs to the operation on heart apparatus, be specifically related to a kind of bovine pericardium valve leaf shaping dies.
Background technology
Up to now, Cardiac Surgery patient in home and abroad adopts valve replacement and aortic valve two class methods that are shaped aortic incompetence is undergone surgery to rescue.Prosthetic valve replacement is to be machinery or biovalve with original valve replacement, and operating difficulty is less, and curative effect is better.But postoperative exists: 1. long-term anticoagulant therapy; 2. receive artificial valve's size restriction not to be suitable for the little patient of child, aortic root and the female patient of fertility needs.And the annuloplasty band art to be aortic valve with pathological changes fold and suspend the purpose of recovering valvular function to reach in midair, its advantage is that operating difficulty is little, has kept original lobe leaf and anatomical structure thereof.But postoperative aortic valve functional rehabilitation is poor, and surgical engine can be high once more.Give thus patient and family members thereof economical with exert heavy pressures on mentally.Therefore, a kind of can to keep aortic valve very important at the good modus operandi of anatomical structure and function in research.Along with the development of biomedical engineering, the bovine pericardium biovalve of handling through biotechnology at present has been widely used in the displacement of aortic valve.And how fast bovine pericardium to be trimmed to horseshoe-shaped valve alternative, be urgent problem.
Summary of the invention
The object of the present invention is to provide a kind of bovine pericardium valve leaf shaping dies that is used for, to realize that bovine pericardium is trimmed to horseshoe-shaped valve alternative.
Technical scheme of the present invention is: bovine pericardium valve leaf shaping dies, and it comprises the single-lobe leaf of three hard, and three single-lobe interlobar septum straight lines are located on the substrate of hard, and the length of substrate is the aortal inwall girth of human heart; The profile phase of the profile of three single-lobe leaves and SANYE aortic valve valve together.
Distance between the single-lobe mould is: 1.04+0.14n, wherein n is a natural number.
Substrate and single-lobe leaf are stainless steel materials.
Above-mentioned bovine pericardium valve leaf shaping dies apparatus is convenient to molding, during use, bovine pericardium valve leaf shaping dies is sticked on bovine pericardial material, can easily prune out the lobe leaf that needs replacement along the single-lobe mould of three hard.Mould structure is simple, and is easy to use, and bio-imitability is strong.
Description of drawings
Fig. 1 bovine pericardium valve leaf shaping dies.
The specific embodiment
As shown in Figure 1, three single- lobe leaves 1,2,3 straight lines at interval are located on the substrate 4 of hard and form overall structure.The length L of substrate is the aortal inwall girth of human heart.Distance L 1 between the single-lobe leaf is: 1.04+0.14n, wherein n is a natural number.And the profile phase of the profile of three single-lobe leaves and SANYE aortic valve valve together.
The length L of aforesaid substrate; Distance L 1 between the wide big or small single-lobe leaf of three single-lobe impellers calculates the bovine pericardium valve leaf shaping dies collection of illustrative plates of 15,17,21,23,25,27,29,31,33 different models respectively according to the anatomic parameter of measuring all ages and classes and body weight patient aortic valve, and is as shown in table 1.
Bovine pericardium valve leaf shaping dies size (mm of unit) table 1
Wherein the high H of single-lobe leaf is the vertical dimension of single-lobe leaf summit to the substrate lower edge, and the lower edge here is the vertical dimension of the lower edge when placing mould like Fig. 1.
During use, according to patient's age, measured body weight heart parameters, select the mould model of lobe according to parameter after, mould fitted in is trimmed to horseshoe-shaped valve alternative on the bovine pericardium.
The leaf shape of bovine pericardium valve and patient's the aortic valve anatomical shape and the size of different model of using this mould blanking is basic identical, and use its advantage of repairing aortic valve and be: the patient is accurate to bovine pericardium cutting size according to the standard of mould in the art; Save time, laborsaving, improve operation efficient and success rate; Can be used for the sufferer aortic valve prosthesis of children's and different weight.Different patient's easy master the method; Cost of manufacture is low, and is cheap.
Claims (3)
1. bovine pericardium valve leaf shaping dies, it comprises the single-lobe leaf of three hard, it is characterized in that three single-lobe interlobar septum straight lines are located on the substrate of hard, the length of substrate is the aortal inwall girth of human heart; The profile phase of the profile of three single-lobe leaves and SANYE aortic valve lobe leaf together.
2. bovine pericardium valve leaf shaping dies according to claim 1, it is characterized in that the distance between the single-lobe leaf is: 1.04+0.14n, wherein n is a natural number.
