At a strain of 16N an ideal mesh should show an elasticity of at least 25% in vertical stretching and 15% in horizontal stretching to achieve almost physiological properties.在16N 的压力下,理想的补片纵轴能够表现出25%的延 展,横轴能够表现出15%的延展以适应腹壁生理 性变化
Conclusions : since intra-abdominal pressure is known to stretch the vertical plane of the abdomen twice more than the horizontal plane,
mesh implantation with the rigid axis oriented vertically would predispose patients to deleterious physiologic sequelae. 结论:在腹内压力的作用下,腹壁的纵轴延展性为横轴的2倍,如 果放置补片的时候将补片刚性的轴顺着腹壁纵轴来放置对患者的腹壁生理调节会产生不利影响
