Title (EN) MEDICAL KNIFE
(FR) LAME MEDICALE
(JA) 医療用ナイフ
Abstract:
(EN) Provided is a medical knife which can be more easily handled and makes it possible to maintain low penetration resistance, without the maximum-width parts of said medical knife creating sudden changes in penetration resistance even when passing through tissue. A knife (A) comprises: a pointed tip (4); a cutting part (1) which has edges (5) consisting of first oblique faces (6) which are formed along the outer periphery and second oblique faces (8) which are formed inside the first oblique faces (6); maximum-width parts (2) which are formed contiguously with the cutting part (1); and a shank part (3) which is formed contiguously with the maximum-width parts (2). The cutting part (1) is formed in such a way that the shape of the planar projection thereof becomes wider from the pointed tip (4) towards the maximum-width parts (2), and the first oblique faces (6) extend further towards the shank part (3) side than the second oblique faces (8) over at least one portion of the area running from the maximum-width parts (2) to the shank part (3).
(FR) L'invention concerne une lame médicale pouvant être manipulée plus facilement et permettant de maintenir une faible résistance à la pénétration, sans que les parties à largeur maximale de ladite lame ne provoquent de soudains changements de résistance à la pénétration lorsqu'elles traversent un tissu. Cette lame (A) comprend : une pointe (4) ; une partie coupante (1) comprenant des bords (5) constitués de premières faces obliques (6) formées sur le périmètre extérieur et de deuxièmes faces obliques (8) formées à l'intérieur des premières faces obliques (6) ; des parties à largeur maximale (2) formées contiguës à la partie coupante (1) ; et une partie tige (3) formée contiguë aux parties à largeur maximale (2). La partie coupante (1) est formée de sorte que la forme de son élément saillant plan devienne plus large de la pointe (4) vers les parties à largeur maximale (2) et que les premières faces obliques (6) s'étendent plus loin vers le côté partie tige (3) que les deuxièmes faces obliques (8) sur au moins une partie de la zone allant des parties à largeur maximale (2) à la partie tige (3).
(JA) 【課題】小さい刺通抵抗を保持し、且つ最大幅部が組織を通過しても急激な刺通抵抗の変化を生じさせることがなく、操作性を向上することができる医療用ナイフを提供する。 【解決手段】ナイフAは、鋭い先端4と、外周に沿って形成された第1斜面6によって構成されたエッジ5および第1斜面6の内側に形成された第2斜面8を有する刃部1と、刃部1と連続して形成された最大幅部2と、最大幅部2と連続して形成されたシャンク部3と、を有し、刃部1は平面投影形状が鋭い先端4側から最大幅部2に向かって幅寸法が大きくなるように形成され、最大幅部2からシャンク部3側にかけての少なくとも一部分において第1斜面6が第2斜面8よりもシャンク部3側に存在している。
