Microrobot assisted laparoscopic urological surgery in a canine model

Area of Science:

• Minimally Invasive Surgery
• Robotics in Medicine
• Urological Surgery

Background:

• Robotic technologies have significantly advanced surgical procedures.
• Laparoscopic surgery offers benefits but can be limited by visualization.
• Microrobots represent a novel approach to enhance surgical visualization.

Purpose of the Study:

• To report the first use of microrobots for laparoscopic urological surgery.
• To evaluate the feasibility of microrobots in a canine model.
• To assess the utility of mobile camera robots in assisting surgical procedures.

Main Methods:

• Nonsurvival laparoscopic radical prostatectomy and nephrectomy were performed in a canine model.
• Microrobots were inserted into the insufflated abdomen via a 15 mm laparoscopic port.
• Microrobots provided remote-controlled, mobile visualization of the abdominal cavity.

Main Results:

• Two procedures, one laparoscopic prostatectomy and one laparoscopic nephrectomy, were successfully completed.
• Microrobots offered enhanced views from multiple angles, aiding surgical performance.
• The microrobots functioned as a mobile viewing platform during the procedures.

Conclusions:

• Miniature camera robots (microrobots) offer a valuable mobile viewing platform in surgery.
• Microrobots have the potential to expand the capabilities of robotic surgery.
• Further development of microrobots could enhance surgical armamentarium for urologists.
