Abstract

The invention provides an intravascular calcified plaque impact fracture device, which comprises a balloon catheter, an ultrasonic transducer and a balloon arranged on the balloon catheter, wherein the ultrasonic transducer comprises a first conductive lead, a second conductive lead and an annular body arranged in the balloon and arranged on the balloon catheter in a sleeving mode, the annular body comprises a first annular electrode layer, a piezoelectric effect layer and a second annular electrode layer, the first annular electrode layer is located on the inner side in the radial direction, the second annular electrode layer is located on the outer side in the radial direction, the piezoelectric effect layer is located between the first annular electrode layer and the second annular electrode layer, and comprises a plurality of piezoelectric ceramic parts and a plurality of polymer parts without piezoelectricity, and the polymer parts and the piezoelectric ceramic parts are distributed in the circumferential direction of the annular body at intervals. According to the intravascular calcified plaque impact fracture device, the intravascular calcified plaque impact fracture effect can be well achieved, a stress ring on the calcified plaque is broken, and balloon plasty and stent implantation can be conveniently carried out.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an impact breaking device for intravascular calcified plaque. Background technique [0002] Vascular calcification is a ubiquitous common pathological manifestation of atherosclerosis, hypertension, diabetic vasculopathy, vascular injury, chronic kidney disease, and aging. [0003] For the treatment of vascular calcification, the existing technology provides a method of treating calcification with an ultrasonic balloon, the specific method is as follows: the outer surface of the ultrasonic balloon coated with a pre-prepared air microbubble coating is delivered to the lesion and stretched , make the balloon contact with the diseased tissue, and then apply ultrasonic waves through the ultrasonic transducer inside the balloon, the sulfur hexafluoride air bubbles in the pre-set air microbubble coating will produce cavitation effect under the action of the ultrasonic transdu...
