ABSTRACT:
A robotized laparoscopic system capable of executing commands of an operating surgeon is provided. The laparoscopic system includes a cylindrical tube inserted through an incision. A small-sized camera is attached to one end of the tube to capture the images of the surgical site. A bending portion is adapted to bend the tip of the tube in any direction. A driving unit controls a bending direction and a bending angle of the bending portion. A movement device moves the tube forward or backward in a longitudinal direction. A control unit independently controls the driving unit and the movement device. An input unit receives commands from the surgeon. A conversion unit converts the command input from the surgeon into digital signals and transmits the digital signals to the control unit. A support unit supports the weight of the movement device by being connected to an operating table or the floor.
