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 ...

Abstract

The invention discloses an intravascular ultrasound catheter and a rapid forming method thereof. The catheter comprises a sleeve tube which is of a one-time formed structure. A transducer with a rotation driving wire is arranged at the far end of the sleeve tube, and the near end of the sleeve tube is connected with a driving / retreating device. A wire guide opening is formed in the far end of the sleeve tube. The method includes the steps that the sleeve tube is formed through a one-time forming method; the wire guide opening is formed in the far end of the sleeve tube. According to the intravascular ultrasound catheter and the rapid forming method thereof, the one-time forming method is used for forming the sleeve tube, production efficiency is greatly optimized, production cost is lowered, no connecting section exists, the reliability of the catheter is improved, and surgical risks are reduced.

Description

Technical field [0001] The invention relates to the field of intravascular ultrasound, in particular to an intravascular ultrasound catheter and a rapid prototyping method thereof. Background technique [0002] Intravascular ultrasound imaging can accurately assess the degree of stenosis in the lumen, and can also be used to detect the vulnerability and plaque load of atherosclerotic plaque, as well as the expansion and restenosis after stent implantation, so it is widely used clinical diagnosis. Its working principle is to place a miniature ultrasonic transducer in the front section of the catheter through a transmission line in a catheter with a length of about 1300-1600mm and a diameter of about 3.0-3.5F, and the IVUS catheter is sent to the target transformation site through the guide wire. Through the IVUS catheter, the intravascular ultrasound system can accurately determine the blood vessel condition at the target change through the ultrasound signal. [0003] The IVUS cat...
