An Overview of Snake like Units

Abstract

In this paper is presented a few models of a robotic snake like unit which can be used in Minimally Invasive Surgery (MIS). In particular, this paper focuses on the flexible unit details. It’s rigid links can be fabricated using selective materials that are light-weight and slim. Thus, this flexible unit can be inserted through one small cavity. Finally, we show that the selected flexible unit may be a very good alternative for Single Port Access (SPA) surgery or this can be used in other environments as well.
