PROBLEM TO BE SOLVED: To provide a medical tool for guide wire fixation by which a guide wire is reliably fixed even when much water is included in a catheter, a damage on the surface of the guide wire and deformation of the guide wire due to external force are not caused, and satisfactory operability of the guide wire is kept when performing insertion and pulling off operation of the catheter.SOLUTION: The tool is composed of: a cylindrical connector main body part 2 which has a catheter connection part 3 having a lumen formed on the side of a distal end, a first connection part 5 formed on a proximal end, and an airtightness maintaining member 10 maintaining the guide wire in an airtight manner and touching the inside of the side of the proximal end thereof and a guide wire fixation part 6 which has a roller member 13 by which the guide wire can be operated in a freely fixing and opening manner, a roller member insertion path 16 making the roller member freely rotate-movable, a second connection part 12, and a pressure member 18 impart-holding airtightness when the first connection part is connected with the second connection part and formed at the distal end of the second connection part. The roller member is rotated and moved to the side of the proximal end of the guide wire fixation part and fixes the guide wire.COPYRIGHT: (C)2009,JPO&INPIT【課題】カテーテル内において水分が多い状態でも確実にガイドワイヤーを固定でき且つガイドワイヤー表面への損傷及び外力による変形が起きず、カテーテルの挿入及び抜去操作の際にガイドワイヤーの操作性を良好に維持可能なガイドワイヤー固定用医療用具。【解決手段】先端部側に形成された内腔を有するカテーテル接続部3、基端部側に形成された第一連結部5、及びガイドワイヤーを気密的に保持する気密性保持部材10、を基端部側に内接する筒状のコネクター本体部2と、ガイドワイヤーを固定/開放自在に操作可能なローラー部材13、ローラー部材を回転移動自在にするローラー部材挿通路16、第二連結部12、第一連結部と第二連結部とが連結された時に気密性を付与保持する圧迫部材18が第二連結部の先端部に形成されたガイドワイヤー固定部6と、から構成され、ローラー部材がガイドワイヤー固定部の基端側に回転移動してガイドワイヤーを固定する。【選択図】図2
