Embodiment Construction

[0049] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0050] Such as figure 1 As shown, the existing IVUS catheter is generally composed of a withdrawal tube 1, a proximal transmission tube 2, a distal acoustic window 3, and a tip 4, and the tip 4 is provided with a guide wire port 41. The extruder intelligently extrudes a pipe of one material. If the catheter needs four kinds of pipes, then it is necessary to connect these four independent pipes through the secondary molding process. The methods include: welding, bonding, etc., that is, the above-mentioned each The components need to be formed independently and then assembled together through secondary molding. The ...

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 ultrasonic catheter and a rapid forming 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 burden of atherosclerotic plaques, as well as the expansion and restenosis after stent implantation, so it is widely used in clinical diagnosis. Its working principle is that in a catheter with a length of about 1300-1600mm and a diameter of about 3.0-3.5F, a miniature ultrasonic transducer is placed in the front part of the catheter through a transmission line, and the IVUS catheter is sent to the target site through the guide wire. Through the IVUS catheter, the intravascular ultrasound system can accurately judge the blood vessel condition at the target change through the ultrasound signal. [0003] The IVUS catheter ...
