Laparoscopic surgery is performed by entering patientu27s abdominal area with two surgical tools and a laparoscope through small insertions. An assistant is required to hold and move the laparoscope to keep the operation site in the view while surgeon manipulates the two surgical tools. Timely, accurate, and stable adjustments of the laparoscope cannot be guaranteed in lengthy operations due to fatigue of human assistant. We propose a system that includes a robot that replaces the human assistant and automatically tracks the tip of a surgical tool during the operation to solve the problem. The robot can be used as a part of the future telesurgical set-up. Surgeon may want to have an automated access to various medical data and images pertain to the patient. A surgeon-computer interface is proposed that features realtime laparoscopic image processing. The proposed system allows surgeon to retrieve information by recognizing surgical tool gestures and motions.
