Embodiment Construction
[0049] The embodiments of the present invention will be described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention. Detailed implementation modes and specific operation procedures are given, but the protection scope of the present invention is not limited to the following implementations. example.
[0050] Such as figure 1 As shown, the existing IVUS catheter is generally composed of a retractor tube 1, a proximal transfer tube 2, a distal acoustic window 3, and a tip 4. The tip 4 is provided with a guide wire port 41. The existing catheter is made of a The machine intelligently extrudes a pipe of one material. If four pipes are required for the catheter, then the four independent pipes need to be connected through a secondary molding process. The methods include welding, bonding, etc., that is, the above The parts need to be formed independently, and then combined together through secondary molding. The process is ...
