description Provided is a device for endoscopic surgery that enables a technician to easily obtain desired images, and has good operability. The device for endoscopic surgery is provided with: a sheath tube body (302) that is inserted inside a body cavity through a body wall; an endoscope insertion passage (304) disposed inside the sheath tube body (302); a surgical instrument insertion passage (306) disposed inside the sheath tube body (302); a position sensor (310) that detects the degree of movement of a surgical tool insertion part (202) relative to the sheath tube body (302) when the surgical tool insertion part (202) moves back or forth; a non-sensing region in which the range of an observed image obtained by an endoscope (100) is not altered if the degree of movement of the surgical tool insertion part (202) is within a prescribed range, when the degree of movement of the surgical tool insertion part (202) is detected by the position sensor (310); and a control unit (314) that alters the range of the observed image in response to the degree of movement of the surgical tool insertion part (202) if the degree of movement of the surgical tool insertion part (202) is not within the prescribed range.
