Introduction to Robotic Surgery
Robotic surgery, a subset of minimally invasive surgery, employs robotic systems to aid surgeons in performing precise and complex procedures. These systems translate a surgeon’s hand movements into smaller, more accurate movements of tiny instruments inside the patient’s body. The primary goal is to enhance surgical capabilities, reduce patient recovery time, and minimize the risk of complications.
Historical Evolution
The roots of robotic surgery can be traced back to the 1980s with the development of computerized surgical assistance systems. However, it wasn’t until the late 1990s that robotic-assisted surgery began to gain traction. The approval of the da Vinci Surgical System by the U.S. Food and Drug Administration (FDA) in 2000 marked a significant milestone, leading to widespread adoption across various medical specialties. Since then, advancements in robotics, imaging, and artificial intelligence have driven continuous improvements in surgical robotics.
