Abstract
Stapler, in particular for hemorrhoidal use, includes a body, an elongate, fixed jaw part connected to the body and including a curved anvil defining staple-forming pockets and a curved portion defining an opening bound on lateral and longitudinal sides, an actuating jaw part including a curved staple driver and optionally a cutting knife, a trigger coupled to the body for actuating the actuating jaw part and an adjustment mechanism for moving the actuating jaw part to vary a longitudinal dimension of the opening defined between a staple cartridge and the anvil. When the actuating jaw part is actuated by the trigger, the staple driver forces staple blanks in the staple cartridge into staple-forming pockets of the anvil to form staples in tissue retained in the opening, while the cutting knife, when present, amputates the tissue.
