Abstract

According to the one embodiment of the present invention, an anastomosis device includes: a first jaw and a second jaw opposite the first jaw and moves between an open position and a closed position with respect to said first jaw; a bracket, to which either the first jaw or the second jaw is fixed and which rotates together with the first and the second jaws; a supporting shaft, the distal end of which is connected to said bracket so as to rotate about a proximal end of said bracket; a drive shaft installed, in the same direction in which the first jaw extends, in a channel formed inside the first jaw; a plurality of anastomosis parts initially allocated on the first jaw; a blade allocated under the anastomosis part and installed on said drive shaft, which translates as the drive shaft rotates and cuts a part of tubular tissue by means of the translation; a wedge having an inclined plane that drives the anastomosis part such that the anastomosis part can pass tubular tissue toward the second jaw and connect said tubular tissue; a driving gear which includes a driving unit and which drives the drive shaft and said bracket, wherein said driving unit is provided with a driving gear that provides driving force; and a rotating gear connected to the bracket and rotatable together with the bracket by means of the driving force provided by said driving gear; and an anastomosis gear connected to the drive shaft and rotatable with said drive shaft.
