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 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 mainly adopts valve replacement and aortic valvuloplasty two class methods to carry out Surgical correction to aortic incompetence.Prosthetic valve replacement be by original valve replacement for machinery or biovalve, operating difficulty is less, and curative effect is better.But postoperative existence: 1. long-term anticoagulant therapy; 2. be not suitable for by the size restriction of artificial valve the female patient that the little patient of child, aortic root and fertility need.And cardiac valvoplasty carries out the aortic valve of pathological changes to fold and suspend in midair to reach the object recovering valvular function, its advantage is that operating difficulty is little, remains original lobe leaf and anatomical structure thereof.But postoperative aortic valve functional rehabilitation is poor, and surgical engine can be high again.Give patient and family members thereof in economy thus and exert heavy pressures on mentally.Therefore, study a kind of can retain aortic valve anatomical structure and the good modus operandi of function very important.Along with the development of biomedical engineering, be widely used in the displacement of aortic valve at present through the bovine pericardium biovalve of biotechnology process.And bovine pericardium is trimmed to horseshoe-shaped valve alternative how fast, be urgent problem.
Summary of the invention
The object of the present invention is to provide a kind of for bovine pericardium valve leaf shaping dies, be trimmed to horseshoe-shaped valve alternative to realize bovine pericardium.
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 of three single-lobe leaves is identical with the profile of SANYE aortic valve valve.
Distance between single-lobe mould is: 1.04+0.14n, and wherein n is 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, sticks on bovine pericardial material by bovine pericardium valve leaf shaping dies, and the single-lobe mould along three hard easily can prune out the lobe leaf that needs are replaced.Mould structure is simple, and easy to use, bio-imitability is strong.
Accompanying drawing explanation
Fig. 1 bovine pericardium valve leaf shaping dies.
Detailed description of the invention
As shown in Figure 1, the substrate 4 that three single-lobe leaf 1,2,3 spaced linear are located at hard forms overall structure.The length L of substrate is the aortal inwall girth of human heart.Distance L1 between single-lobe leaf is: 1.04+0.14n, and wherein n is natural number.And the profile of three single-lobe leaves is identical with the profile of SANYE aortic valve valve.
The length L of aforesaid substrate, distance L1 between the size single-lobe leaf of three single-lobe impeller exterior features 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 measuring all ages and classes and body weight patient aortic valve, as shown in table 1.
Bovine pericardium valve leaf shaping dies size (unit mm) table 1
Wherein single-lobe leaf height H is the vertical dimension of single-lobe leaf summit to substrate lower edge, and lower edge is here the vertical dimension as lower edge when Fig. 1 places mould.
During use, according to age, the measured body weight heart parameters of patient, after the mould model of Selecting parameter lobe, mould is fitted on bovine pericardium and carry out being trimmed to horseshoe-shaped valve alternative.
The leaf shape of bovine pericardium valve applying the different model of this mould blanking is substantially identical with size with the aortic valve anatomical shape of patient, applies its advantage of repairing aortic valve to be: in art, patient is accurate to bovine pericardium cutting size according to the standard of mould; Save time, laborsaving, improve procedure efficiency and success rate; May be used for the sufferer aortic valve prosthesis of children's and different weight.Different patient easily grasps the method; Cost of manufacture is low, cheap.
Claims (2)
1. a 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, and the length of substrate is the aortal inwall girth of human heart; The profile of three single-lobe leaves is identical with the profile of SANYE aortic valve lobe leaf; Distance between single-lobe leaf is: 1.04+0.14n, and wherein n is natural number, and parasang is mm.
2. bovine pericardium valve leaf shaping dies as claimed in claim 1, is characterized in that substrate and single-lobe leaf are stainless steel materials.
