In modern biomedical technology,it is a more cutting-edge research to use biomedical materials as alternative materials for making medical assistance implements.In this paper,under the theory of modern cervical splint design,we researched the sliced veneer laminated timber cervical splint characteristics from micro-structure,and constructed a new sliced veneer laminated timber cervical splint.The paper gave the optimal size of sliced veneer of the molded cervical splint,and calculated the theoretical elastic modulus and its correlation coefficient which would impact its strength.Furthermore,we got the mechanical expression by deducing these the quantitative mathematical relation between the elastic modulus of coefficients and sliced veneer laminated timber cervical splint.This provided a basis for the micromechanics theory of cervical splint composite elastic mechanics,and provided experimental proofs.
