| titleOfInvention | Intravascular Ultrasound Catheter Transducer Drive Shaft |
| abstract | The present disclosure relates to a transmission shaft of an intravascular ultrasound catheter transducer, which is characterized by comprising: an inner layer structure, which is formed as a first spring structure braided by braided wires, and the pitch of the first spring structure is from The distal end to the proximal end gradually increases; and the outer layer structure covers the inner layer structure, the outer layer structure is formed as a second spring structure, and the pitch of the second spring structure gradually increases from the distal end to the proximal end, the first The pitch of the two-spring structure is more sparse than the pitch of the first-spring structure. In this case, the mechanical properties of the inner structure and the outer structure of the drive shaft are complementary, so that the flexibility of the drive shaft can be improved while the stress response capability and torque transmission capability of the drive shaft can be enhanced, which helps to avoid the occurrence of Uneven rotation artifact, while improving the twist control performance on the long-range control of the intravascular ultrasound catheter, improving the overall maneuverability, effectively reducing the operation time, and providing medical services more efficiently. |
