Problem to be solved: to provide a surgical cutting device which facilitates the rotation of the cutting window by minimizing the effect on the visibility of the user.The cutting device 10 includes a first tubular member 16, a second tubular member 18, a sleeve member 20, a third tubular member, and an orienting member 22.A distal portion of the first tubular member includes a cutting tip.A distal region of the second tubular member forms a cutting window.The first elongated member is disposed coaxially within the second tubular member so that the cutting tip is selectively exposed in the cutting window.The first tubular member and the second tubular member are disposed coaxially with the sleeve member.The third tubular member is disposed coaxially with an intermediate portion of the first tubular member, an intermediate region of the second tubular member, and a sleeve member.The orientation member is capable of transmitting a rotational force and selectively rotating the second tubular member and the third tubular member against the sleeve to achieve the space rotation of the cutting window.Diagram【課題】ユーザの可視性への影響を最小限に抑えて、切断窓の回転を容易にする、外科用切断器具を提供する。【解決手段】第１の管状部材１６と、第２の管状部材１８と、スリーブ部材２０と、第３の管状部材と、配向部材２２とを含む外科用切断器具１０。第１の管状部材の遠位部分が切断先端部を含む。第２の管状部材の遠位領域は切断窓を形成している。切断先端部が切断窓において選択的に露出されるように、第１の細長い部材は第２の管状部材の内部に同軸に配設されている。第１の管状部材および第２の管状部材はスリーブ部材の内部に同軸に配設されている。第３の管状部材は、第１の管状部材の中間部分、第２の管状部材の中間領域、およびスリーブ部材の周囲に同軸に配設されている。配向部材は、回転力を伝達して、第２の管状部材および第３の管状部材をスリーブに対して選択的に回転させ、切断窓の空間回転を達成するために回転可能である。【選択図】図１
