SURGICAL APPARATUS AND ANVIL DELIVERY SYSTEM THEREFOR

摘要

An apparatus for delivering a surgical device to a predetermined location within a tubular organ includes an elongated delivery member having a proximal and a distal end, a mounting mechanism for detachably mounting the surgical device at the distal end of the elongated delivery member and a releasing mechanism for releasing the surgical device from the mounting mechanism. A detachable anvil assembly for use with an apparatus for performing circular anastomosis of tubular organs includes an elongated anvil rod having proximal and distal end portions and an anvil head mounted to the distal end portion of the anvil rod. The distal end portion is pivotally mounted and is adapted to pivot approximately plus or minus ninety degrees relative to a longitudinal axis defined by the rod. An elongated delivery member detachably receives the anvil assembly and facilitates delivery of the anvil assembly to the operative site. The pivoting feature of the distal end reduces the transverse profile of the assembly which consequently facilitates introduction and advancement of the anvil assembly within the tubular organ.
