ABSTRACT
The field of surgery is entering a time of great change, spurred on by remarkable recent advances in surgical and computer technology. Only recently have robotic systems made their way into the operating room as dexterity-enhancing surgical assistants and surgical planners, in answer to surgeons' demands for ways to overcome the surgical limitations of minimally invasive laparoscopic surgery. The first generation of surgical robots is already being installed in a number of operating rooms around the world. These aren't true autonomous robots, but they are lending a mechanical helping hand to surgeons. Remote control and voice activation are the methods by which these surgical robots are controlled. Robotics is being introduced to medicine because they allow for unprecedented control and precision of surgical instruments in minimally invasive procedures. The ultimate goal of the robotic surgery field is to design a robot that can be used to perform closed-chest, beating-heart surgery. Robots in the field of surgery have dramatically changed the procedures for the better. The most significant advantage to Robotic Surgery to the patient is the decrease in pain and scaring. The smallness of the incisions also causes many other advantages that make Robotic Surgery worth the risk. Besides the obvious rewards to the patient, Robotic Surgery is also very advantageous to the surgeon and hospital.
INTRODUCTION:
Just as computers revolutionized the latter half of the 20th century, the field of robotics has the potential to equally alter how we live in the 21st century. We've already seen how robots have changed the manufacturing of cars and other consumer goods by streamlining and speeding up the assembly line. We even have robotic lawn mowers and robotic pets. And robots have enabled us to see places that humans are not yet able to visit, such as other planets and the depths of the ocean. In the coming decades, we may see robots that have artificial intelligence. Some, like Honda's ASIMO robot, will resemble the human form. They may eventually become self-aware and conscious, and be able to do anything that a human can. When we talk about robots doing the tasks of humans, we often talk about the future, but robotic surgery is already a reality. Doctors around the world are using sophisticated robots to perform surgical procedures on patients. While robotic surgery systems are still relatively uncommon, several hospitals around the world have bought robotic surgical systems. These systems have the potential to improve the safety and effectiveness of surgeries. But the systems also have some drawbacks. It's still a relatively young science and it's very expensive. Some hospitals may be holding back on adopting the technology. Robotic surgery is the use of robots in performing surgery. Three major advances aided by surgical robots have been remote surgery, minimally invasive surgery and unmanned surgery.
HISTORY:
In 1985 a robot, the PUMA 560, was used to place a needle for a brain biopsy using CT guidance. In 1988, the PROBOT, developed at Imperial College London, was used to perform prostatic surgery. The ROBODOC from Integrated Surgical Systems was introduced in 1992 to mill out precise fittings in the femur for hip replacement. Further development of robotic systems was carried out by Intuitive Surgical with the introduction of the da Vinci Surgical System and Computer Motion with the AESOP and the ZEUS robotic surgical system.
• In 1997 a reconnection of the fallopian tubes operation was performed successfully in Cleveland using ZEUS.
• In May 1998, Dr. Friedrich-Wilhelm Mohr using the Da Vinci surgical robot performed the first robotically assisted heart bypass at the Leipzig Heart Centre in Germany.
• In October 1999 the world's first surgical robotics beating heart coronary artery bypass graft (CABG) was performed in Canada using the ZEUS surgical robot.
• In 2001, Prof. Marescaux used the Zeus robot to perform a cholecystectomy on a pig in Strasbourg, France while in New York.
• The first unmanned robotic surgery took place in May 2006 in Italy.
ROBOTIC SURGEONS:
The first generation of surgical robots are already being installed in a number of operating rooms around the world. These aren't true autonomous robots that can perform surgical tasks on their own, but they are lending a mechanical helping hand to surgeons. These machines still require a human surgeon to operate them and input instructions. Remote control and voice activation are the methods by which these surgical robots are controlled. Robotics is being introduced to medicine because they allow for unprecedented control and precision of surgical instruments in minimally invasive procedures. So far, these machines have been used to position an endoscope, perform gallbladder surgery and correct gastroesophogeal reflux and heartburn. The ultimate goal of the robotic surgery field is to design a robot that can be used to perform closed-chest, beating-heart surgery. According to one manufacturer, robotic devices could be used in more than 3.5 million medical procedures per year in the United States alone. Here are three surgical robots that have been recently developed:
• da Vinci Surgical System
• ZEUS Robotic Surgical System
• AESOP Robotic System
CLASSIFICATION :
Not all surgical robots are equal. There are three different kinds of robotic surgery systems:
• Supervisory-controlled systems
• Telesurgical systems
• Shared-control systems.
The main difference between each system is how involved a human surgeon must be when performing a surgical procedure. On one end of the spectrum, robots perform surgical techniques without the direct intervention of a surgeon. On the other end, doctors perform surgery with the assistance of a robot, but the doctor is doing most of the work.
There are mainly three telesurgical robotic systems namely da Vinci Surgical System, ZEUS Robotic Surgical System and AESOP Robotic System.
SUPERVISORY-CONTROLLED ROBOTIC SURGERY SYSTEMS :
Of the three kinds of robotic surgery, supervisory-controlled systems are the most automated. But that doesn't mean these robots can perform surgery without any human guidance. In fact, surgeons must do extensive prep work with surgery patients before the robot can operate. Dr. Scott J. Boley demonstrates a robotic surgery system at the Montefiore Institute for Minimally Invasive Surgery in New York City.
