Embodiment

[0037] Example: Please refer to Figures 1 through 8 ：

[0038] The present invention proposes a controllable guide tube, comprising: catheter 1; the distal end of the catheter 1 is the electrode head 3; the proximal end of the catheter 1 is a rotary fine-tuning sleeve 2; the outer end of the rotating fine-tuning sleeve 2 is connected to the rotation of the adjustment box 4; the outer end of the adjustment box 4 is vertically fixed with a handle 5; the middle of the adjustment box 4 is provided with a rotating mechanism 6; the upper end of the adjustment box 4 is provided with a damping frame 7; the catheter 1 is built with a stainless steel pull wire 8.

[0039] Further, according to embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the proximal end of catheter 1 is a rigid tube, the distal end of catheter 1 is a flexible tube, which can facilitate catheter 1 into the body, after entering the body, the tip portion may be conveniently bent.

Abstract

The invention provides a controllable guiding directional catheter, and relates to the technical field of medical instruments. An electrode tip is arranged at the far end of the catheter; the near end of the catheter is provided with a rotary fine-tuning sleeve; the outer end of the rotary fine adjustment sleeve is rotationally connected with the adjusting box; a handle is vertically and fixedly mounted in the middle of the outer end of the adjusting box; a rotating mechanism is vertically arranged in the middle of the adjusting box; a damping frame is arranged at the inner end of the upper end face of the adjusting box. And a stainless steel pull wire is arranged in the guide pipe. The electrode tip is jointly composed of at least 10 platinum-iridium alloys, the 10 platinum-iridium alloys are designed to be gradually changed in hardness from the electrode tip end to the catheter body end, the remote controllability is improved while the safety is considered, intracavity electrocardiosignals can be clearly recorded, and the problems that the amplitude of a rotating catheter part is not easy to control, and the catheter body is not easy to rotate are solved. And internal organs are easily injured by the tip part of the catheter.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a controllable guide guide tube. Background [0002] Interventional therapy is a kind of minimally invasive treatment using modern high-tech means, under the guidance of medical imaging equipment, the characteristic catheters, guide wires and other precision medical devices are introduced into the human body for the establishment of pathways, delivery devices or drugs. [0003] In the existing catheter design and manufacture, most of them mold the distal end of the catheter into different curved shapes to meet different vascular anatomy, or rotate the handle part so that the catheter tip is bent, and the amplitude of the rotating catheter part is not easy to control, which is easy to make the tip of the catheter damage the internal organs. Contents of the Invention [0004] In view of this, the present invention provides a controllable guide tube, which has a rotating...
