Clinical Study for Evaluating the Clinical Safety and Effectiveness of the Automated Robotic Robot, Revo-i Surgical Robot System (Model MSR-5100), Used for General Endoscopic Surgery.

This study is based on the ergonomic features of the most common surgical procedures, which require advanced techniques and relatively difficult operations, such as pancreatobiliary surgery, prostatectomy, nephrectomy, colon and rectal resection. This study id designed to verify the clinical safety and effectiveness of 'Revo-i Surgical Robot System (Model MSR-5100), developed by Mirae Company to overcome the limitations of general laparoscopic surgery.
