自动侵入性手术工具的精确控制需要实时识别组织类型及其变形。本文的胎儿是硬膜外穿刺术，研究表明，对于硬膜外穿刺术，组织类型和变形可以分别从基于激光的光谱和推动针穿过各种组织所需的力的变化来确定，研究表明，每个患者之间的生理差异太大，无法可靠地使用绝对值来指示针尖的位置。然而，侵彻过程中的力变化模式在不同的试件之间是相似的。结合光谱技术对该信息的解释可用于区分针尖的组织和组织结构。本文描述了在工具作用下用于解释组织类型和变形的自动技术的研究结果。
Precise control of automated invasive surgical tools requires real-time identification of tissue types and their deformation. At the fetus of this paper is the epidural puncture, for which it is shown that the tissue type and deformation can respectively be determined from laser-based spectroscopy and the change in force required to push the needle through the various tissues, Studies have shown that physiological variations from one patient to another are too great to allow absolute values to be reliably used to indicate the position of the needle tip. However, the pattern of force variation during penetration is shown to be similar between specimens. Interpretation of this information in conjunction with spectroscopic techniques can be used to discriminate between tissues and tissue structure at the needle tip. This paper describes results from an investigation on automatic techniques for interpreting the type and deformation of tissues under tool action.
