<p>A hemostat provided with a disposable staple-carrying cartridge movably attached thereto. The jaws of the hemostat are parted, through an opening at the forward end of the cartridge, and, for example, a bleeding organic tubular structure is positioned between the hemostat jaws. The jaws of the hemostat are closed, clamping the "bleeder" therebetween, and then the opening at the forward end of the cartridge is closed. The cartridge is subsequently moved so that the closed forward end of the cartridge is displaced away from a position surrounding the hemostat jaws and into a position surrounding the bleeder. The cartridge is activated by the surgeon, and a U-shaped staple is urged forward, made to surround the bleeder and then seals the same. After the seal, the hemostat is removed. Means are provided for preventing misfiring of the cartridge when a staple is in an improper position, or when the cartridge is exhausted of its supply of staples.</p> |
