Abstract

There has been a continuing push to reduce the invasiveness of surgery by accessing the abdominal cavity through a single incision, such as with laparoendoscopic single-site (LESS) surgery. Although LESS procedures offer significant benefits, added complexities still inhibit the procedures. Robotic surgery is proving to be an excellent option to overcome these limitations. This paper presents the experimental results of the single-incision in vivo surgical robot (SISR), a multifunctional, dexterous, twoarmed robot capable of performing surgical tasks while overcoming the issues associated with manual LESS operations. In vivo surgical procedures have been used to demonstrate the efficacy of using a robotic platform over traditional laparoscopic tools. The most recent experimental test resulted in the first successful in vivo robotic LESS colectomy utilizing a robot completely contained within the abdominal cavity. In this test, SISR showed significant benefits including access to all quadrants in the peritoneal cavity and improved dexterity.
