The invention provides an operational robot for minimally invasive celiac surgery, which belongs to the technical field of surgical robots and comprises a casing, a rotational structure, an endoconch, a translational structure, a bionic mouth structure and an incoming line structure, wherein the endoconch is arranged inside of the casing; the rotation structure is fixedly arranged at the inner side of the casing and is contacted with the endoconch to drive the casing to rotate corresponding to the endoconch; the translation structure is fixedly arranged in the middle of the outer side of the casing; and the bionic mouth structure is fixedly arranged inside of the endoconch. Comparatively complicated operation is realized in the enterocoelia of a human body by the operational robot for minimally invasive celiac surgery in the invention, the method that the operational part bionic mouth structure of the robot is used for collecting and carting post-operation remnants from the human bodyis proposed by the invention in a groundbreaking manner. Compared with the traditional method that remnants are clipped out after the belly is punched, the method in the invention reduces the wound greatly, shortens the surgery time containing anesthesia, and can take out all remnants in the belly in a single operation.
