Robotic surgery is a kind of minimally invasive surgery. "Minimally invasive" implies that we use miniaturized surgical instruments that fit through a number of quarter-inch incisions rather than operating on patients through large incisions. When performing surgery using the the world's most advanced surgical robot da Vinci three separate robotic arms are used to mount these miniaturized instruments, that allows the surgeon maximum flexibility and precision. This prsentation is about the past, present and future of Robotic Surgery and also explaining the different advanges of Robotic Surgery
Robotic surgery was developed to overcome the limitations of minimally invasive surgery where instrument does not has articulating facility. Instead of directly moving the instruments, the surgeon uses one of two methods to control the instruments ; either a direct telemanipulator or by computer control. A telemanipulator is a remote manipulator that allows the surgeon to perform the normal movements associated with the surgery whilst the robotic surgical arms carry out those movements using end-effectorss and manipulators to perform the actual surgery on the patient. In computer-controlled systems the surgeon uses a computer to control the robotic arms and its end-effectors, though these systems can also still use telemanipulators for their input.
There's a magnified high-definition 3-D camera in The da Vinci's fourth arm that guides choices during the procedure. The surgeon uses console found in the operating room to controls these instruments and also the camera. They can operate all four arms from the da Vinci simultaneously by putting his fingers in to the master controls, while looking via a stereoscopic high-definition monitor that place him within the patient, giving him a improved, more detailed 3-D look at the operating site which cannot be achieved through the human.
