PROBLEM TO BE SOLVED: To provide an angle fixing implement, despite a simple configuration, capable of easily and surely fixing a distal end tool or the like extending from a bending portion that bends freely, in a free direction and at a free angle by fixing the bending portion in a desired shape.SOLUTION: This angle fixing implement 1 covers the periphery of the bending portion 11 having multiple joints and bending freely, and fixes the angle. The angle fixing implement includes: a plurality of sleeves 2, 3, and 4 disposed in series along the bending portion 11 a fixing sleeve 5 provided adjacent to the third sleeve 4 and having a locking lever an angle adjusting dial 8 coming into contact with the fixing sleeve 5 and a second locking member 9 coming into contact with the first sleeve 2. This angle fixing implement operates the locking lever 6 to bring the fixing sleeve 5 in pressure contact with the angle adjusting dial 8, and to bring one end of the locking lever 6 into pressure contact with the end face of the third sleeve 4, such that the first sleeve 2 comes into pressure contact with the second locking member 9 to fix the shape of the bending portion 11.COPYRIGHT: (C)2013,JPO&INPIT【課題】簡易な構成でありながら、自在に屈曲する湾曲部を所望の形状に固定することで、湾曲部から延出する先端工具等を自在な方向及び角度で容易かつ確実に固定可能な角度固定具を提供する。【解決手段】多関節を備え自在に屈曲する湾曲部11の周囲を被覆し角度を固定する角度固定具1であって、湾曲部11に沿って直列に配置される複数のスリーブ2,3,4と、第3のスリーブ4に隣接して設けられ,ロックレバーを備える固定用スリーブ5と、この固定用スリーブ5に当接する角度調整ダイヤル8と、第1のスリーブ2に当接する第2の係止部材9と、を備え、ロックレバー6を操作し、固定用スリーブ5を角度調整ダイヤル8に圧接させるとともに、第3のスリーブ4の端面にロックレバー6の一端を圧接させることで,第1のスリーブ2を第2の係止部材9に圧接させ、湾曲部11の形状を固定可能に構成されることを特徴とする。【選択図】図1
