Dexterous miniature robot for advanced minimally invasive surgery

Area of Science:

• Minimally Invasive Surgery
• Robotics in Medicine
• Surgical Technology

Background:

• Single-incision laparoscopic surgery presents challenges in instrument positioning and triangulation.
• Open surgical procedures remain highly invasive, posing significant risks to patients.
• Miniature robotic platforms offer potential for enhanced dexterity and reduced invasiveness in surgery.

Purpose of the Study:

• To demonstrate the feasibility of a miniature robotic platform for complex single-incision, minimal access surgery.
• To evaluate the capabilities of a novel robotic system in performing advanced laparoscopic procedures.
• To assess the potential clinical benefits of robotic assistance in single-incision surgery.

Main Methods:

• A miniature robot platform was designed with a dexterous in vivo robot and a remote surgeon interface.
• A standard laparoscope was integrated for vision and lighting.
• Multiple robots were inserted through a single incision for procedures, including tissue retraction and visualization.
• The system's efficacy was tested in a nonsurvival cholecystectomy in a porcine model.

Main Results:

• The miniature robot platform demonstrated speed, dexterity, and tissue-handling comparable to standard laparoscopic instruments.
• The robotic system successfully performed a single-incision cholecystectomy in a porcine model.
• The feasibility of using multiple robots through a single incision for advanced laparoscopic surgery was confirmed.

Conclusions:

• Miniature robotic platforms are feasible for performing complex single-incision, advanced laparoscopic surgery.
• This technology has the potential to offer significant clinical benefits by reducing invasiveness and enhancing surgical capabilities.
• The developed robotic system shows promise for future applications in minimally invasive surgical procedures.
