Summary: | PROBLEM TO BE SOLVED: To provide a surgical stapling apparatus that is relatively economical to develop and manufacture and to store and ship, and economical and convenient to purchase and use from an end user's perspective.SOLUTION: An end effector 400 of a surgical stapling apparatus 10 includes: a mounting portion; a first jaw member 410 and a second jaw member 420 that extend distally from the mounting portion; a drive beam engageable with the first and second jaw members; and a threaded drive screw. The first jaw member includes a first tissue engaging surface, and the second jaw member supports a fastener cartridge. The drive beam includes a retention foot, and the retention foot defines a threaded bore that supports a threaded insert. The threaded drive screw is threadably engaged with the threaded insert, and distally advances the drive beam along the threaded drive screw to fire fasteners.
【課題】開発および製造、貯蔵および輸送が比較的経済的であり、ならびにエンドユーザーの観点からは購入および使用が経済的かつ簡便である、外科手術ステープル留め装置を提供する。【解決手段】外科手術ステープル留め装置10のエンドエフェクター400は取り付け部分と、取り付け部分から遠位方向に延びている第1の顎部材410および第2の顎部材420と、第1の顎部材および第2の顎部材と係合可能である駆動梁と、ねじ式駆動ねじとを含む。第1の顎部材は、第1の組織係合表面を含み、第2の顎部材は締め具カートリッジを支持している。駆動梁は、保持フットを含み、保持フットは、ねじ式ボアを規定し、ねじ式ボアは、ねじ式インサートを支持している。ねじ式駆動ねじは、ねじ式インサートとねじ式に係合されており、ねじ式駆動ねじは、駆動梁をねじ式駆動ねじに沿って遠位方向に前進させ、締め具を発射する。【選択図】図1 |
