In 1985, the first documented robot-assisted surgery is occurred, PUMA 560 arm was used in a delicate neurosurgery biopsy. In 2000, da Vinci robotic surgery was approved by FDA for the general laparoscopy. This is well-suited for accomplishing complex using a minimal invasive approach, and is controlled by surgeon from a console. Surgeon can utilize this precise machine in the same room as patient, uses four interactive robotic arms which three of them act as surgical tools and the last one holds camera. This system allows surgeon’s hands to movements to be translated into smaller, precise movements of tiny instruments inside the patient’s body.

By providing surgeons with superior visualization, enhanced dexterity, greater precision and ergonomic comfort, the da Vinci Surgical System makes it possible for more surgeons to perform minimally invasive procedures involving complex dissection or reconstruction. For the patient, a da Vinci procedure can offer all the potential benefits of a minimally invasive procedure, including less pain, less blood loss and less need for blood transfusions. Moreover, the da Vinci System can enable a shorter hospital stay, a quicker recovery and faster return to normal daily activities.

Though Intuitive Surgical has had to overcome many obstacles in order to dominate the digital surgery field, it is now a multimillion-dollar business that continues to grow. Besides the cost, the da Vinci Surgical System still has many obstacles that it must overcome before it can be fully integrated into the existing healthcare system. From the lack of tactile feedback to the large size, the current da Vinci Surgical System is merely a rough preview of what is to come. More improvements in size, tactile sensation, cost, and telesurgery are expected for the future.
