An anastomat and closure device having a pressure sensor and automatic adjustment means, that a pressure value from direct or indirect contact of a stapling apparatus and a staple holder can be transmitted and displayed by a pressure sensor. The pressure sensor is installed on either side or on both sides of the stapling apparatus and the staple holder and wherein the pressure is displayed through a pressure sensor shaping circuit, an amplifying circuit, and a display circuit. The benefit of this invention is that surgical operators can intuitively and directly understand the pressure of the anastomotic tissue and determine whether the pressure is appropriate.
