Moving-around-point mechanism for laparoscope equipment

A moving-around-point mechanism for laparoscope equipment comprises a swing arm supporting rod, a swing arm joint, a swing ram rod and a parallelogram link. The upper end of the swing arm supporting rod is connected with the action end of a rotating mechanism, the swing arm joint is arranged on the lower portion of the swing arm supporting rod, the swing arm rod is installed on the swing arm joint, the swing arm body is hinged to one end of the parallelogram link, the other end of the parallelogram link is hinged to a support used for installing a tail end mechanism of laparoscope, and the swing arm supporting rod, the swing ram joint, the swing arm rod, the parallelogram link and the support of the tail end mechanism form a parallelogram structure used for achieving the purpose that the laparoscope moves around a cut-point. The moving-around-point mechanism for the laparoscope equipment is good in controllability and high in locating precision.
