摘要：PROBLEM TO BE SOLVED: To provide an active cannula for biosensing and surgical intervention, which has the dexterity to be maneuvered around anatomical features in order to gain access to otherwise unreachable surgical sites.SOLUTION: A surgical cannula comprises: a first flexible tube having a first pre-formed curvature; a second flexible tube having a second pre-formed curvature, wherein the second flexible tube is disposed within the first flexible tube. The first and second flexible tubes store elastic energy, wherein the storage is adapted such that the stored elastic energy changes depending upon the operation of the second flexible tube on the first flexible tube, and the first and second flexible tubes are configured such that at least one of the two flexible tubes changes its shape when the stored energy is changed.
