Abstract
【解決手段】把持具に接合された固定軸5と、この固定軸上を長手方向に変位するために装着された摺動軸6、摺動軸を予設定された前方変位力により近位の不動作位置から遠位の動作位置へ変位させる、前記把持具内の電動式駆動部とを有する外科用骨パンチにおいて、摺動軸6が止め18を担持し、この止め18が、摺動軸6が動作位置へ変位する間に弾性ばね要素17に衝突し、弾性ばね要素17が、固定軸5上で支持されると共に、摺動軸6が変位する間に駆動部の前方変位力に反作用することが提案される。

- 把持具に接合された固定軸と、
この固定軸上を長手方向に変位するために装着された摺動軸と、
前記摺動軸を、予設定された前方変位力により、近位の不動作位置から遠位の動作位置へ変位させる、前記把持具内の電動式駆動部と、
を有する外科用骨パンチにおいて、
前記摺動軸(6)が止め(18)を担持し、かつ、前記止めが、前記摺動軸(6)が前記動作位置へ変位する間に弾性ばね要素(17)に衝突し、かつ、前記弾性ばね要素(17)が、前記固定軸(5)上で支持されると共に、前記摺動軸(6)が変位する間に前記駆動部の前記前方変位力に反作用すること、
を特徴とする外科用骨パンチ。 - 請求項1記載の骨パンチであって、前記摺動軸(6)が前記不動作位置から前記動作位置へ変位する間に、変位経路の一部分以降においてのみ、前記弾性ばね要素(17)が作用を発揮して前記前方変位力に反作用するよう、前記摺動軸(6)の前記止め(18)と、前記弾性ばね要素(17)と、前記固定軸(5)上にある前記弾性ばね要素(17)の支持体(16)とが配置されかつ寸法されていることを特徴とするもの。
- 請求項1又は2記載の骨パンチであって、前記固定軸(5)が、圧縮ばねとして構成された弾性ばね要素(17)用の受けチャンバ(16)を有し、前記摺動軸(6)上に配置された止め(18)が、前記受けチャンバ内へ延び、前記摺動軸(6)が前方変位する間、前記弾性ばね要素(17)を圧縮することを特徴とするもの。
- 先行する請求項のいずれか1項記載の骨パンチであって、前記摺動軸(6)を備えた前記固定軸(5)が、解放可能に前記把持具(2)に接合され、かつ前記把持具(2)から取り外し可能であることを特徴とするもの。
- 請求項4記載の骨パンチであって、
摺動軸(6)を備えた幾つかの交換可能な固定軸(5)のセットが前記骨パンチに割り当てられ、これらの軸のうちの少なくとも幾つかが、異なる前方変位力により使用できる異なる寸法の刃先(12)を担持すること、及び
固定軸(5)と摺動軸(6)とから成る各ユニットが、前記前方変位力に反作用する弾性ばね要素を持たないか、或いは、異なるばね特性を有する弾性ばね要素(17)を持ち、前記駆動部により生成される前記前方変位力が、前記1つ又は複数の刃先(12)に完全に作用するか、又は各ばね特性に応じて異なる低減された程度まで作用すること、
を特徴とするもの。 - 請求項5記載の骨パンチであって、前記異なるユニットの前記1つ又は複数の刃先(12)が、異なる幅を有することを特徴とするもの。
