Single-port laparoscopy minimally invasive surgery robot system

The invention discloses a single-port laparoscopy minimally invasive surgery robot system, which comprises a function end and a control end, wherein the function end comprises a function mechanical arm, an image shooting illumination module and a sleeve pipe module, the control end comprises an image shooting illumination module control module, a function mechanical arm control module and a fixing module, the image shooting illumination module control module can realize the extension, retraction and bending of the image shooting illumination module, and the function mechanical arm control module can realize the extension, retraction and bending of the function mechanical arm and the opening and the closing of a tail end executer so that the image shooting illumination module and the function mechanical arm can enter the operation position of the abdominal cavity in the posture of retracting into the sleeve pipe module, and in addition, after the function mechanical arm reaches the operation position through a single cut, and in addition, the image shooting illumination module and the function mechanical arm can move to the specific space position to enter the work posture after reaching the operation position. The maximum diameter of the function end of the single-port laparoscopy minimally invasive surgery robot system is only 12mm, so the single-port laparoscopy minimally invasive surgery robot system has the advantages that the size is small, the use is convenient, safety is realized, and the like.
