Robotic surgery or computer assisted surgery is a type of minimally invasive surgery. “Minimally invasive” means that instead of operating on patients through large incisions, we use miniaturized surgical instruments that fit through a series of quarter-inch incisions. It was developed to enhance the capabilities of surgeons performing open surgery. During this surgery, instead of directly moving the instruments, the surgeon uses one of two methods to control the instruments, either a direct telemanipulator or through computer control. A telemanipulator is a remote manipulator that permits the specialist to perform the regular actions associated with the surgery while the robotic arms carry out those movements using end-effectors and manipulators to perform the actual surgery on the patient.
