Summary
This study introduces a novel modular robotic surgery concept, integrating single incision and needlescopic techniques. A prototype demonstrates the feasibility of assembling robotic modules for minimally invasive procedures through small abdominal incisions.
Area of Science:
- Minimally Invasive Surgery
- Robotic Surgery
- Surgical Technology
Background:
- Advancements in minimally invasive surgery and robotic systems aim to reduce incision size and number.
- This paper proposes a novel approach combining modular robotic surgery, single incision laparoscopic surgery, and needlescopic surgery.
Purpose of the Study:
- To present and demonstrate a new concept for modular robotic surgery.
- To evaluate the performance of assembled robotic modules for minimally invasive procedures.
Main Methods:
- Robotic modules carrying surgical tools are inserted through the navel.
- Modules are assembled within the abdominal cavity and connected to 3-mm needle shafts that penetrate the abdominal wall.
Main Results:
- A prototype of a three degree-of-freedom (3-DOF) robotic module (16mm diameter, 51mm length) was successfully designed and built.
- The performance of three interconnected robotic modules was evaluated.
Conclusions:
- A novel modular robotic surgery concept was proposed and validated through prototyping.
- The study evaluated the performance of connected modules and outlined future challenges and research directions.
