Surgical robotic system is an advanced surgical tool that enables surgeons to perform precise operation with high-quality. It has been proved that some surgical robotic systems contribute to more precise and safer surgical operation in clinical environments. In this article, classification of the surgical robotic systems is proposed at first. Several technologies required for compact and high performance surgical robotic system are presented using examples of surgical robotics system for minimally invasive general abdominal surgery. They are miniaturized driving mechanism, multi-degrees of freedom bending forceps, integrated laser coagulation manipulator, and system integration. Finally, safety issues in surgical robotics design are discussed using an example of laparoscopic manipulator.
