Development of a Novel Wasp-Inspired Friction-Based Tissue Transportation Device.

ABSTRACT: Currently existing tubular transportation systems for the extraction of large tissue masses during Minimal Invasive Surgery (MIS) are subjected to a large amount of operating limitations. In this study, a novel transportation mechanism (patented) was developed inspired by the egg-laying structure of wasps. The developed mechanism consists of an outer tube within which six reciprocating semi-cylindrical blades are present and tissue is transported using a friction differential between the blades. Two motion sequences were developed: (1) 1-5 motion sequence, in which one blade moves forward, while the remaining five blades move backward and (2) 2-4 motion sequence, in which four blades move backward while two blades move forward. A proof-of-principle experiment was performed to investigate t
