Abstract
A position information transmitting member for transmitting position information to a staple receiving portion is provided in a tissue stapler having a staple receiving portion which comprises the anvil of the stapler. Thereby, an operator can easily locate the position of and grasp the staple receiving portion located within a tissue to swiftly execute stapling. The tissue stapler includes a stapling portion provided with an endoscope inserting tube path, a stapling portion provided with a staple injecting portion arranged on a distal end side of the inserting portion, and a staple receiving member (anvil) arranged separately from the inserting portion, to be grasped by a treatment tool introduced via the inserting portion in a state when it is opposed to the stapling portion via a tissue, to bend a distal end portion of a staple pressed out from the staple injecting portion of the stapling portion which has penetrated through the tissue.
