Abstract

Background: Existing methods used to perform laparoendoscopic single-site surgery (LESS) require multiple laparoscopic tools that are inserted into the peritoneal cavity through a single, specialized port. These methods are inherently limited in visualization and dextrous capabilities by working through a single access point. A miniature in vivo robotic platform that is completely inserted into the peritoneal cavity through a single incision can address these limitations, providing more intuitive manipulation capabilities and improved visualization. +Methods: The miniature in vivo robotic platform for LESS consists of a multi-functional robot and a remote surgeon interface. The robot has two arms and specialized end effectors that can be interchanged to provide monopolar cautery, tissue manipulation, and intracorporeal suturing capabilities. +Results: This robot has been demonstrated in multiple non-survival procedures in a porcine model, including four cholecystectomies. +Conclusion: This study demonstrates the effectiveness of using a multi-functional miniature in vivo robot platform to perform LESS.
