Abstract
Background: Many minimally invasive surgical procedures and assisting robotic systems have been developed to further minimize the number and size of incisions in the body surface. This paper presents a new idea combining the advantages of modular robotic surgery, single incision laparoscopic surgery and needlescopic surgery.Material and methods: In the proposed concept, modules carrying therapeutic or diagnostic tools are inserted in the abdominal cavity from the navel as in single incision laparoscopic surgery and assembled to 3-mm needle shafts penetrating the abdominal wall.Results: A three degree-of-freedom robotic module measuring 16 mm in diameter and 51 mm in length was designed and prototyped. The performance of the three connected robotic modules was evaluated.Conclusion: A new idea of modular robotic surgery was proposed, and demonstrated by prototyping a 3-DOF robotic module. The performance of the connected robotic modules was evaluated, and the challenges and future work were summarized.
