Description
一実施態様において、遠位部はロックタブを備えるとともに、ハンドル内の対応するロックスロットを介してハンドルに取り付け可能である。
一実施態様において、組織治療機構は、長尺状の中空部材の遠位端内に受け入れられた組織の周りを締め付けるために結紮バンドを長尺状の中空部材の遠位端から放つための結紮バンド展開機構を備える。
一実施態様において、組織治療機構は、長尺状の中空部材の遠位端内に受け入れられた組織をスネアが切断するように、長尺状の中空部材の遠位端からスネアを作動可能にするためのスネア機構を備える。
本発明はまた方法に関し、該方法は装置の剛性長尺状の中空部材の遠位端をキャビティに挿入することを含み、該装置はプランジャを有し、該プランジャは、中空部材に取り付けられ、且つ、当該プランジャが中空部材の内部を近位に移動する際に中空部材の遠位端において吸引を引き起こすために中空部材の内部を長手方向に摺動するように構成される。本方法は、プランジャが中空部材に対して相対的に近位に摺動し、中空部材の遠位端に組織を引き込むための吸引を発生させるように、プランジャにヒンジ式に結合される引き金を引くことをさらに備える。本方法は、中空部材の遠位端において受け入れられた組織を囲繞するために組織治療機構を作動させることをさらに備える。
