4) will main ring mathematical model import 3D printing pre-processing software in, carry out slicing treatment after using 3D printer into
Row printing.
Compared with prior art, the present invention beneficial effect is:
1, Tricusp Valvuloplasty ring of the invention uses double-deck or more since the intermediate ring segment of main ring is hollow design
Layer structure, compared with the forming ring of existing single layer solid construction, elasticity modulus can be done smaller the elasticity modulus of main ring, be fitted
In myocardium dynamics, weak patient is used.
2, the intermediate ring segment of Tricusp Valvuloplasty ring of the invention, main ring uses bilayer or multilayer structure, is more convenient for carrying out
Flexible adjustment improves the elasticity of vertical direction.
3, the production method of Tricusp Valvuloplasty ring of the present invention, can individuation customize Tricusp Valvuloplasty ring, Tricusp Valvuloplasty
Peripheral curve when the camber line of ring main body loop section is according to applied patient's tricuspid valve normally closed state generates.It is using
When, forming ring can precisely be bonded patient's cusp margin curve, the phenomenon that overcoming the incompetence of tricuspid annulus part.
4, the production method of Tricusp Valvuloplasty ring of the present invention, the section of each ring segment of main ring are the myocardium dynamics according to patient
And determine, therefore there is suitable elasticity, the weaker patient of myocardium dynamics can be matched, prevents valve from opening incomplete.
