Abstract: A control method of an automatic compression circular anastomosis device, includes: correcting a zero point when an operation switch provided in a handle unit is turned on, by a control unit; controlling a motor to compress a tissue in a direction reaching a minimum distance at which a distance between a top surface of an anastomosis unit and a bottom surface of an anvil is minimized, by the control unit; measuring a real-time pressure applied to the tissue and a real-time distance between the top surface of the anastomosis unit and the bottom surface of the anvil in real-time, by the control unit; and controlling, when the real-time pressure and the real-time distance reach a set pressure and a set distance Dr stored in advance, the anastomosis unit to cut unnecessary parts of the tissue and anastomose the tissue with a plurality of staples, by the control unit.
