Claims (11)

  1. 病巣を治療するための液体を供給する外科用装置において:
    遠位チップを有する細長い部材と;
    前記細長い部材に移動可能に配置された複数の液体供給部材とを備え、前記病巣に液体を供給するために、各々の液体供給部材が一つのルーメンおよび該ルーメンと連通した少なくとも一つの開口部を有しており;
    前記液体供給部材に動作可能に結合されたアクチュエータを備え、該アクチュエータは、前記液体供給部材を、前記細長い部材内の後退位置から前記細長い部材に対して半径方向に延びる第一の展開位置に移動させるための第一の位置へと駆動可能であり、また前記液体供給部材を、前記第一の展開位置から前記細長い部材に対して更に半径方向に延びた第二の展開位置に移動させるための第二の位置へと駆動可能であり、
    前記液体供給部材は保持部材によって前記第一の展開位置および第二の展開位置に保持されることを特徴とする外科用装置。
  2. 請求項1に記載の装置において、更に、前記遠位チップの近位側にある前記細長い部材の側壁に形成された複数の開口部を備え、前記液体供給部材は該開口部を通して展開可能であることを特徴とする装置。
  3. 請求項2に記載の装置において、前記細長い部材の遠位チップは、組織を貫通するように構成された鋭利なチップであることを特徴とする装置。
  4. 請求項2に記載の装置において、前記アクチュエータは、前記複数の液体供給部材を、その後退位置、第一の展開位置、および第二の展開位置の間で移動させるように軸方向に摺動可能であり、前記保持部材は、前記アクチュエータに装着され、且つ前記アクチュエータが摺動可能に収容されるハウジング内に形成された複数の凹部の一つと係合するタブを含んでおり、また当該装置は更に、前記細長い部材の中に摺動可能に装着された支持管を備え、該支持管に前記複数の液体供給部材が連結されることを特徴とする装置。
  5. 請求項2に記載の装置において、前記液体供給部材の遠位端は、前記第一の展開位置および第二の展開位置において前記細長い部材の遠位チップから遠位方向に延びないことを特徴とする装置。
  6. 請求項2に記載の装置において、前記複数の液体供給部材の一つは、前記細長い部材の長手方向軸線と実質的に整列した展開位置に延びることが可能であり、前記長手方向軸線に対して或る角度で半径方向に延びることが可能な他の前記液体供給部材の直径よりも小さい直径を有することを特徴とする装置。
  7. 請求項2に記載の装置であって、更に、前記複数の液体供給部材の位置を表示するための視認可能なインジケータを備えることを特徴とする装置。
  8. 請求項2に記載の装置において、前記液体供給部材における少なくとも一つの開口部は該部材の側壁に形成され、また該側壁には複数の開口部が含まれることを特徴とする装置。
  9. 請求項7に記載の装置において、前記視認可能なインジケータは、前記液体供給部材が前記後退位置、第一の展開位置または第二の展開位置に展開されたかどうかを表示するために、前記ハウジングの窓を通して見えるインジケータを備えることを特徴とする装置。
  10. 請求項7に記載の装置において、前記視認可能なインジケータは、当該装置の近位端に、前記液体供給部材の半径方向での配向を表示するためのマーキングを含み、該マーキングは、当該装置が貫通する皮膚装着パッチと整列可能であることを特徴とする装置。
  11. 請求項2に記載の装置であって、更に、前記細長い部材に摺動可能に装着された深さインジケータを備えることを特徴とする装置。
