Abstract
【解決手段】処置具10は、体腔内において対象臓器に所定の処置を加える処置部12と、上記処置部12を先端に備えた軟性管部20及び、軟性状態及び硬性状態を選択的に切り替え可能な切り替え管部22を備える挿入部14と、を有する。
【選択図】図1
Description
体腔内において対象臓器に所定の処置を加える処置部と、
上記処置部を先端に備えた軟性管部及び、軟性状態及び硬性状態を選択的に切り替え可能な切り替え管部を備える挿入部と、
を具備することを特徴とする。
前記の具体的実施形態から、以下のような構成の発明を抽出することができる。
上記処置部を先端に備えた軟性管部及び、軟性状態及び硬性状態を選択的に切り替え可能な切り替え管部を備える挿入部と、
を具備することを特徴とする処置具。
一実施形態において、体腔58が上記体腔に、対象臓器52が上記対象臓器に、処置部12が上記処置部に、軟性管部20が上記軟性管部に、切り替え管部22が上記切り替え管部に、挿入部14が上記挿入部に、処置具10が上記処置具に、それぞれ対応する。
この(1)に記載の処置具によれば、処置部が先端に形成された常に軟性管部と、硬性及び軟性の両方をとる切り替え管部と、を有するので、生体内へは柔軟に変形して容易に挿入でき且つ処置時には自体が動くことのない処置具を提供できる。
この(2)に記載の処置具によれば、挿入部の切り替え管部は、体腔挿入時に軟性、処置時に硬性になるので、体腔への挿通孔の直近の処置部位以外でも処置が容易である。
上記操作部は、上記挿入部の上記切り替え管部の上記軟性状態及び硬性状態を切り替え選択するための選択部を有することを特徴とする(1)に記載の処置具。
一実施形態において、操作部16が上記操作部に、ダイヤル28が上記選択部に、それぞれ対応する。
この(3)に記載の処置具によれば、切り替えのための選択部は体外にあるので、操作性が良い。
一実施形態において、ダイヤル44及び46が上記姿勢操作部に対応する。
この(4)に記載の処置具によれば、軟性管部の姿勢を自在に調整して、処置部を対象臓器の処置対象部位に設定できる。
Claims (4)
- 体腔内において対象臓器に所定の処置を加える処置部と、
上記処置部を先端に備えた軟性管部及び、軟性状態及び硬性状態を選択的に切り替え可能な切り替え管部を備える挿入部と、
を具備することを特徴とする処置具。 - 上記挿入部の上記切り替え管部は、上記体腔内に挿入されるときには軟性状態を、上記体腔内において上記臓器に上記所定の処置を加えるときには硬性状態をとることを特徴とする請求項1に記載の処置具。
- 上記所定の処置時に体外に配置される位置に形成された、上記処置部を操作するため操作部を更に具備し、
上記操作部は、上記挿入部の上記切り替え管部の上記軟性状態及び硬性状態を切り替え選択するための選択部を有することを特徴とする請求項1に記載の処置具。 - 上記操作部は、更に、上記軟性管部の姿勢を操作する姿勢操作部を有することを特徴とする請求項3に記載の処置具。
