Abstract

A stapling device includes first and second arms, each arm having a distal portion, a central portion and proximal portion; a stapler head rotatably coupled to a free end of the distal portion of the second arm. The stapler head has a first, inoperative position and a second operative position. The device includes a member for moving the stapler head from the inoperative position to the operative position, and elements for pivotally coupling the central portion of the first arm to the central portion of the second arm. The stapling device further includes first and second handle elements each pivotally coupled to each other and to the proximal portions of the first and second arms and operatively coupled to the moving member so that initial displacement of the handle elements from an inoperative position towards each other moves the distal portions of the first and second arms towards each other and actuates the moving member to move the stapler head from the inoperative position to the operative position. Further displacement of the handle elements displaces the second arm to bring the stapler head and the first arm into contact with tissue structure to be stapled. Release of the handle elements allows the moving member to return the stapler head to the inoperative position.
