PAVR (Percutaneous Aortic Valve Replacement) operation conveying device with valve positioning function

Abstract

The invention discloses a PAVR (Percutaneous Aortic Valve Replacement) operation conveying device with a valve positioning function. The device comprises an active valve, a gripping device, a positioning rod, a regulating line, a hinge pin, an ultrasonic transducer, a microwave probe, a control device, a power supply device and a shell; the active valve is arranged at the tail end of the gripping device; the other end of the gripping device is connected with the positioning rod; the ultrasonic transducer is arranged at the right side of the shell; the tail end of the ultrasonic transducer is connected with the device shell by the hinge pin; the tail end of the ultrasonic transducer is connected with the regulating line; the control device is arranged at the outer end of the shell; the power supply device is connected with the control device. The PAVR operation conveying device with the valve positioning function has a simple structure and can take a good assisting effect on positioning on an implanted valve; intelligent control of the control device can improve a success rate of a PAVR operation, reduce operation difficulty, reduce postoperative complications, reduce operation pain and risks for patients, and reduce medical cost.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a delivery device for percutaneous aortic valve replacement operation with valve positioning function. Background technique [0002] At present, according to relevant statistical data, the incidence of aortic valve stenosis caused by aortic valve calcification is as high as 2% to 7% among the elderly over 65 years old, and the proportion increases with age. In patients with severe aortic stenosis, the left ventricular function is severely impaired, the quality of life of the patients is reduced, and the survival time is significantly shortened. Effective treatment is necessary. To date, surgical prosthetic aortic valve replacement remains the treatment of choice for those patients for whom surgery is an indication. [0003] In 2002, based on a large number of animal experiments, Alain Cribier performed transcatheter aortic valve replacement for a 57-year-old patient ...
