Robotic Surgery

Robotic surgery is a type of minimally invasive surgery, using a tiny opening to get inside the body instead of making a large cut. It uses small tools attached to a thin robotic arm, which is controlled by the surgeon. Robotic surgery may be referred to by the specific kind of robot that is used. The most advanced robot currently in use is called the da Vinci, and surgery using it is sometimes called da Vinci surgery.

There are many benefits to robotic surgery, both for the patient and the surgeon. Robotic surgery allows for more precise movements and increased control during very delicate surgical procedures. This makes performing surgery accurately much easier for surgeons and reduces fatigue. The smaller 'hand' of the robot can enter the body via a much smaller opening, which reduces the risk of infection and scarring and leads to a faster recovery. The robotic hands also contain tiny moveable cameras among their tools, giving surgeons a much closer view of the procedure than would be possible with traditional surgery.
