ABSTRACT
The field of surgery is entering a time of great change, spurred on by remarkable recent advances in surgical and computer technology. Computer-controlled diagnostic instruments have been used in the operating room for years to provide help for vital information through ultra-sound, Computer –Aided Tomography (CAT), and other imaging technologies.
The robotic surgical system enables surgeons to remove gallbladders and perform other general surgical procedures while seated at a computer console and 3-D video imaging system across the room from the patient. The surgeons operate controls with their hands and fingers to direct a robotically controlled laparoscope.
ROBOTIC SURGERY
Robotic surgery is the latest technological advancement that introduces the Robotic technology in the field of surgery. 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.
They provide surgeons with the precision and dexterity necessary to perform complex, minimally invasive surgical (MIS) procedures, such as beating-heart single-or double-vessel bypass and neurological, orthopedic and plastic surgery, among many other future applications.
WHAT MAKES ROBOTIC SURGERY POWERFUL?
The Laparoscopic surgery-in which instruments are inserted through small incisions-has been used by surgeons whenever possible. Patients are less traumatized, require shorter hospital stays and heal faster than with conventional surgery.
Laparoscopic instruments are mainly limited to scissors and staplers to close incisions or attach blood vessels. It also has graspers to manipulate tissue. The instruments enter the body through a long tube; a video image from a tiny camera called an endoscope poked through another incision guides the surgeon. For a relatively simple procedure like gallbladder removal, the tools work well enough.
But surgeons cannot use the instruments to perform complicated tasks like sturing and knot tying. Because of these limitations, most operations can’t be performed endoscopically.
