<p>The present invention relates to a medical device for multiple bends in which a plurality of bending portions for bending operation are disposed in an insertion portion for insertion into a body. An object of the present invention is to provide a medical device for multiple bends in which the distal end of the insertion portion can be precisely operated. A medical device for multiple bends, includes a distal-side traction member (36u, 36d, 361, 36r) which is inserted through the distal-side bending portion (25) and the proximal-side bending portion (26), which is configured to bend the distal-side bending portion in the bending orientation (U, D, L, R), and which includes a distal-side fixing portion (38u, 38d, 381, 38r) fixed to the distal end of the distal-side bending portion in the axial direction, and a proximal-side traction member which is inserted through the proximal-side bending portion (26), which is configured to bend the proximal-side bending portion in the bending orientation (U, D, L, R), and which includes a proximal-side fixing portion (39u, 39d, 391, 39r) fixed to the distal end of the proximal-side bending portion in the axial direction, the proximal-side fixing portion (39u, 39d, 391, 39r) is disposed at substantially the same position as the distal-side fixing portion (38u, 38d, 381, 38r) in a circumferential direction.</p> |
