In the present invention, it is possible to move the insertion section of a treatment tool and the insertion section of an endoscope inserted into a trocar in lockstep in the axial direction, and even if the insertion section of the treatment tool is moved minutely in the axial direction, a favorable endoscopic image having no shaking is obtained. In this endoscopic surgery device (1), if there is operation exceeding an amount (t) of play when operating in the direction of insertion/removal of the treatment tool (50), the endoscope (10) is moved in the direction of insertion/removal in lockstep with the motion in the direction of insertion/removal of the treatment tool (50). Also, the treatment tool (50) moves in the axial direction of the trocar (100) at the amount (t) of play with respect to the endoscope (10). Thus, when the treatment tool (50) is moved in the direction of insertion/removal, if the movement is within the range of the amount (t) of play, the endoscope (10) is not moved in the direction of insertion/removal. By means of providing such an amount (t) of play, minute movements of the treatment tool are not transmitted to the endoscope. |
