SISTUM — The single incision system of the Technische Universität München

Single-Port Surgery is a recent development in minimally invasive surgery and denotes abdominal surgery where all instruments are inserted through a single incision. Further progress in the field of surgical intervention can solely be achieved by combined benefits regarding both surgical and technical improvements. The reduction of trauma as well as improvements in ergonomics compared to laparoscopic surgery can be recognized as main objectives. To comply with these requirements, a realtime controlled mechatronic-assisted single-port manipulator SISTUM with sufficient workspace and applied forces for precise tissue manipulation is proposed. With regard to sterility and biocompatibility aspects, the manipulating part of this system - the bio-inspired bending structure - is manufactured using selective laser sintering (SLS) with biocompatible polymers.
