Description
本願は、1998年10月23日付米国特許出願第09/177,950号の継続出願である2000年7月21日付米国特許出願第09/621,029号の継続出願であり、これらの米国特許出願の内容は本願に援用する。
本発明は、切開手術または内視鏡手術に使用して、組織のクランピングおよびシーリングを行なうバイポーラ鉗子に関する。本発明の鉗子は、その遠位端に対向ジョー部材を備えた少なくとも1つの細長シャフトを有している。両ジョー部材は、該両ジョー部材が互いに間隔を隔てて配置される第一位置から、両ジョー部材が協働してこれらの間に組織を掴む第二位置まで相対移動できる。鉗子は電気エネルギ源に接続され、該電気エネルギ源は各ジョー部材に接続されて、両ジョー部材がこれらの間に保持された組織を通してエネルギを導くことができるようになっている。両ジョー部材間に組織が保持されたときに両ジョー部材間のギャップ距離を制御すべく、少なくとも2つの互いに間隔を隔てた非導電性ストップ部材が、両ジョー部材の内向き面上に配置されている。
ここで図1〜図3を参照すると、内視鏡手術に使用するバイポーラ鉗子10が示されており、該鉗子10は、ハンドル組立体18に連結される駆動ロッド組立体11を有している。駆動ロッド組立体11は、近位端16および遠位端14を備えた細長い中空シャフト部分12を有している。添付図面および以下の説明において、伝統的に使用されているように、用語「近位」とは、使用者に近い方のバイポーラ鉗子10の端部をいい、用語「遠位」とは、使用者から遠い方の端部をいう。また、大部分の図面すなわち図1〜図14には内視鏡手術に使用する本発明の器具の一実施形態例えば鉗子10が示されているが、ここに図示しかつ説明するものと同じ発明概念を、例えば図15Aおよび図15Bに示す実施形態のような切開手術器具(open surgical instrument)100に使用するか、該器具100に組み込むことができる。
Claims (9)
- 少なくとも1つの細長シャフトを有し、該シャフトの遠位端には対向ジョー部材が設けられ、該ジョー部材は、両ジョー部材が互いに間隔を隔てた関係に配置される第一位置から、両ジョー部材が協働してこれらの間で組織を掴む第二位置まで相対移動でき、
両ジョー部材がこれらの間に保持された組織にエネルギを通すことができるように各ジョー部材に接続される電気エネルギ源と、
