摘要: 以生物医学为应用背景的生物软组织切割机理研究近年来已成为关注的热点,从生物软组织主要组织成分对切割特性的影响出发,定性分析不同生物软组织的切割特性对理解生物软组织切割机理具有重要的意义。选取三种典型的生物软组织:胶原体含量高的肌腱、弹性体含量较高的动脉管和平滑肌含量较高的胃肌层,在自行搭建的生物软组织切割平台上开展切割试验。从切割力、组织变形、切割能和局部刚度等角度对三种典型软组织的切割特性进行对比研究。定性分析了生物软组织中三种主要组织成分对切割特性的影响:胶原纤维对软组织切割力的影响较大,弹性体对软组织切割变形的影响较大,而平滑肌则对软组织切割特性的影响较小。

Abstract: Biological soft tissue cutting mechanism research for biomedical application background has become a hot focus in recent years. It is very meaningful for understanding biological soft tissue cutting mechanism to qualitatively analysis the cutting characteristics of different biological soft tissues from the view of the effect of three components of biological soft tissue. Three typical biological soft tissues (tendon with many collage fibers, ascending aorta with many elastomers and stomach muscle with a large amount of smooth muscle cells) are selected to carry out cutting experiments on a soft tissue cutting apparatus designed and fabricated by our group. The cutting characteristics of three typical biological soft tissues are analyzed from the view of cutting force, tissue deformation, cutting energy and local stiffness. The effect of three components of biological soft tissue on cutting characteristics is qualitatively analyzed. Collagen fiber has an important influence on the cutting force of biological soft tissue; the elastomer has a significant impact on the tissue cutting deformation; however the smooth muscle cell has little effect on both cutting force and tissue cutting deformation.

Key words: biological soft tissue, cutting characteristics, cutting force, robotic minimally invasive surgery
