AI Technical Summary

Technical Problem

Existing ultrasound catheters are large in size and complex to operate when establishing guidewire access across complex lesions. They are difficult to transmit torque and adjust catheter angle safely and conveniently, and are prone to damaging patient tissues.

Method used

Design an ultrasonic catheter comprising a guidewire channel, a puncture guidewire channel, and a core channel, configured as a parallel and non-coaxial structure, equipped with a catheter retraction section and a locking assembly, allowing the catheter body and the retraction outer tube to rotate relative to each other, and achieving angular self-locking through the locking assembly to prevent axial movement.

Benefits of technology

This approach facilitates the operation of the guidewire pathway, reduces the overall size, improves the safety and accuracy of the surgery, and avoids damage to the patient's tissues.

Abstract

The invention discloses an ultrasonic catheter and ultrasonic equipment, and relates to the technical field of medical equipment. A guide wire channel, a puncture guide wire channel and a core channel which are parallel to one another and not coaxial are arranged in the ultrasonic catheter, the puncture guide wire channel and the core channel are both arranged at the near end of the guide wire channel and are arranged side by side, and the puncture guide wire outlet is communicated with the puncture guide wire channel; the imaging core part is arranged in the core part channel and can rotate and / or move relative to the core part channel; the catheter withdrawing part comprises a connecting tube and a withdrawing inner tube, the connecting tube is fixedly arranged at the near end of the catheter main body, and the withdrawing inner tube is arranged at the near end of the imaging core part in a sleeving manner and can synchronously move with the imaging core part. The catheter body is directly provided with three channels, ultrasonic image recognition and puncture guide wire stretching can be directly conducted, and other catheters do not need to be used in a combined mode; the three channels are parallel to one another and are not coaxial, so that a guide wire passage adapting to a blood vessel occlusion scene can be established through the integrated catheter, and the catheter can be operated to rotate easily.
