title: [The calculation-improving of stress amplification coefficient and the checking of its trouble-shooting model].
abstract: Through mechanical analysis, it is discovered that the twined structure decides the amplification coefficient of the catgut tension. Many troubles of production can be explained with this mechanics model, and it could be used as a reference for medical sutures. The paper gives an accurate calculating formula for catgut design and its direct tensile strength through improving mechanics model. It can raise the material strength from 10 to over 31% depending on its twined structure.
