;; BACKGROUND;Medical Robots;A fundamental property of robotic systems is their ability to couple complex information to physical action in order to perform a useful task. This ability to re- place, supplement, or transcend human performance has had a profound influence on many fields of our society. ;Automate or improve discrete processes provide Access to environments humans cannot safely go;The first is the potential of a medical robot ;The second is the potential of medical robots to promote surgical safety. ;The third is the inherent ability of medical robots and CIS systems . ;CAD/CAM:The process of computer-assisted planning, registration, execution, monitoring, and assessment surgical .;Robotic surgical assistants may be broken into two subcategories. ;1.3 Medical Robotics System Paradigms: Surgical CAD/CAM and Surgical Assistance ;1.3 Medical Robotics System Paradigms: Surgical CAD/CAM and Surgical Assistance ;The mechanical design of a surgical robot depends crucially on its intended application. ;Many early medical robots were essentially modified industrial robots. ;However, the specialized requirements of surgical applications have tended to encourage more specialized designs.;The emergence of minimally invasive surgery has created a need for robotic systems that can provide high degrees of dexterity in very constrained spaces inside the patient’s body, and at smaller and smaller scales. ;The Surgical robots assist surgeons in treating patients by moving surgical instruments, sensors, or other devices in relation to the patient. Generally, these motions are controlled by the surgeon in one of three ways: ;Preprogrammed, semi-autonomous motion: The de- sired behavior of the robot’s tools is specified interactively by the surgeon, usually based on medical images. The computer fills in the details and obtains the surgeon’s concurrence before the robot is moved. Examples include the selection of needle target and insertion points for percuta
