This can be especially helpful during head and neck surgery and pediatric surgery, because of the small size of the surgical field and the inability to maneuver the instruments and the camera within it. It can also help in distinguishing tissue types in oncological dissection [15]. 4.2. Elimination of Physiologic Tremors and Scale Motion sellckchem The surgical system eliminates the surgeon’s tremor through hardware and software filters. In addition, movements can be scaled, whereby large hand movements can be translated into micromovements inside the operative field, allowing the surgeon more precision [1]. 4.3. Multiarticulated Instruments EndoWrist instruments have 7 degrees of freedom, which improves dexterity, allowing maneuverability that approaches that of open surgery. 4.4.

Fatigue Reduction During the robotic portion of the surgery the surgeon is sitting with his/her forearms resting comfortably on a pad and the head resting against the console, therefore improving ergonomics. This results in reduced body fatigue. With the surgeon sitting at a remote workstation, it eliminates the need to physically twist and turn in awkward positions to move instruments within the operative field while simultaneously visualizing a monitor. In addition, hand muscle fatigue is reduced, which when considered together with improved visualization, makes tasks such as suturing substantially easier. Studies suggest (Berguer and Smith [16]) that robotic surgery is less stressful for the surgeon. 4.5.

Restore Proper Hand-Eye Coordination The robotic system eliminates the ��fulcrum effect�� [17] of endoscopic surgery and makes instrument and camera manipulation more intuitive, emulating another property of open surgery. 4.6. Telesurgery Since the inception of robotic surgery, the wish to overcome geographical constraints and the availability of specialists was an important goal. Marescaux and collaborators [18] described the feasibility and safety of a robot-assisted laparoscopic cholecystectomy at distance using high-speed connection between the surgical unit at Strasbourg, France, and the surgical console in New York. Telesurgery allows for these barriers to be overcome as well as offering new teaching and tutoring possibilities. 4.7. Training The robotic system provides some interesting tools and opportunities for teaching.

An experienced surgeon can use another console next to the trainee, which can be activated to command the main arms or auxiliary arms. The Vinci Skills Simulator (Intuitive Surgical Inc.) can be attached to the console, allowing a virtual training environment to be creating while maintaining the same robotic interface Batimastat [19]. However, there are currently no standardized residency curriculums that formally support the teaching of robotic surgical skills [20]. 5. Disadvantages of Robot-Assisted Surgery 5.1.
