Abstract
A snakelike surgical instrument, comprising a handheld structure (); an manipulating structure () comprising an outer frame () hingedly connected to the handheld structure () so that the manipulating structure () has a rotational degree of freedom (R) around a first axis and an inner frame () hingedly connected to the outer frame () so that the manipulating structure () has a rotational degree of freedom (R) around a second axis, the first axis and the second axis forming an angle; an end unit () connected to the handheld structure () by means of a connecting component () and comprising a tool supporting base () and a snakelike structure () connected to the tool supporting base (), the snakelike structure () having degrees of freedom of motion (RR) in the same direction as the manipulating structure (); and a transmission unit () comprising a flexible transmission structure connected to the inner frame () and the snakelike structure (). A mechanical transmission mode is used by the snakelike surgical instrument, the motion of a handheld side can be directly transmitted to the end unit (), complicated force feedback control is avoided, and control is simple.
