A delivery device for percutaneous aortic valve replacement with valve positioning function

Abstract

The invention discloses a delivery device for percutaneous aortic valve replacement surgery with a valve positioning function. A control device, a power supply device and a casing, the aortic valve is arranged at the end of the grabbing device, the other end of the grabbing device is connected with the positioning rod, the ultrasonic transducer is arranged on the right side of the casing, and the ultrasonic transducer The end of the transducer is connected to the equipment casing through the pin shaft, the tail end of the ultrasonic transducer is connected with an adjustment line, the control device is arranged at the outer end of the casing, and the power supply device is connected to the control device. The invention has a simple structure, can play a very good auxiliary role in the positioning of the implanted valve, and the intelligent control of the control device can improve the success rate of percutaneous aortic valve replacement, reduce the difficulty of operation, and reduce postoperative complications. Patients can reduce the pain and risk of surgery and reduce medical expenses.

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 ...
