<p>An apparatus for applying surgical fasteners has an applicator mechanism, with an anvil for applying the fasteners to tissue and a shaft connecting the applicator mechanism to an actuator mechanism. The shaft is flexible to bend during insertion into a body channel to conform to the configuration of the body channel and is capable of retaining said configuration during actuation. The shaft transmits a first, relatively small force from said actuator mechanism to the applicator mechanism hydraulically, and comprises a first sleeve within a second sleeve. The actuator mechanism comprising a slide secured to the first sleeve for moving the anvil. Responsive to the first force, the applicator mechanism produces a second force larger than the first force for applying the fasteners to tissue.</p> |
