Title
(EN) Adjustable bent catheter
(ZH) 可调弯导管
Abstract
(EN)
The utility model provides an adjustable bent catheter which comprises a catheter body and a traction piece, and an adjustable bent section is arranged at the far end of the catheter body. The traction part comprises a traction wire, a wire penetrating pipe, a protective sleeve and a crimping pipe, the far end of the traction wire is connected with the adjustable bent section, the near end of thetraction wire is wrapped and fixed in the crimping pipe, and the other parts of the traction wire sequentially and movably penetrate through the wire penetrating pipe and the protective sleeve from far to near; the near end of the wire penetrating pipe and the far end of the protective sleeve are relatively fixed, no gap exists between the near end of the wire penetrating pipe and the far end of the protective sleeve in the axial direction of the wire penetrating pipe and the far end of the protective sleeve, and the far end of the crimping pipe is movably arranged in the protective sleeve ina penetrating mode. And the crimping pipe moves in the protective sleeve to drive the traction wire to move in the protective sleeve and the wire penetrating pipe, so that the adjustable bent sectionis bent or returns to be straight. The inner cavity of the protective sleeve limits the bending deformation degree of the traction wire, the traction wire can be prevented from being seriously bent orbroken near the near end of the wire penetrating pipe, and it is guaranteed that the bending adjusting function of the adjustable bent catheter is smoothly achieved.
