Background:The degrees of intraoperative movement with rigid standard instruments during laparo-endoscopic surgery are limited to translation, rotation, and pivoting within the insertion point. Additional distal angulation and rotation of the instrument jaws are a potential improvement.Methods:Different types of articulated instruments have been developed and tested in phantom and animal experiments. The final prototype was used on 30 patients during laparoscopic surgery following a standardized test protocol.Results:The final design incorporates elastically linked tubular segments, 0–120° variable curvature, and +/–360° rotation of the jaws element. All functions can be operated with one hand. Testing on phantom and in laparoscopic surgery showed improved handling of organs and tissue with no complications.Conclusion:We were able to demonstrate the feasibility of the technical design and the clinical applicability of a deflectable endoscopic instrument system. Although our initial results indicate an improvement in laparoscopic tissue manipulation, the current deflection and jaw rotation require further technical refinement.
