Abstract

The invention relates to the technical field of puncture equipment, and provides a visual vascular ultrasonic probe for guiding puncture of portal veins and a using method thereof.The equipment comprises a sheathing canal, at least three channels are formed in the sheathing canal, a puncture needle is arranged in one channel, a catheter is arranged in the other channel, and an ultrasonic transducer and a driving shaft are arranged in the catheter; a micro camera assembly is arranged in one channel; the puncture efficiency and accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of puncture equipment, in particular, to a visualized vascular ultrasound probe for guiding puncture of the portal vein and a method of using the same. Background technique [0002] Interventional therapy is a minimally invasive treatment using modern high-tech means, that is, under the guidance of medical imaging equipment, special catheters, guide wires and other precision instruments are introduced into the human body to diagnose and localize the disease in the body. Such as TIPS surgery. The existing operation method is that doctors rely on experience to perform manual puncture in a blinded state, and the doctor needs to have a lot of practical experience to ensure the effectiveness of the puncture. For the more complex vascular distribution in the human body, more precise interventional treatment is required. A visualized vascular ultrasound probe that can directly observe and guide puncture is propos...
