Abstract

The invention provides an intracardiac two-dimensional ultrasonic imaging catheter. The intracardiac two-dimensional ultrasonic imaging catheter comprises a catheter body and an ultrasonic device arranged at one end of the catheter body, wherein the ultrasonic device comprises a plurality of transducer units which are arranged in a linear array, each transducer unit is of a vibrating diaphragm structure, and the diameter or length of a vibrating diaphragm does not exceed 1 / 2 of the wavelength corresponding to the target ultrasonic working frequency. The invention further provides an intracardiac two-dimensional ultrasonic imaging catheter system which comprises an ultrasonic imaging host with the ultrasonic pulse wave Doppler function, the continuous wave Doppler function and the color Doppler function and the intracardiac two-dimensional ultrasonic imaging catheter; and the ultrasonic imaging host is used for generating a two-dimensional ultrasonic image. Compared with a traditional TEE esophageal ultrasound technology, the X-ray dosage and application of a contrast agent in an operation can be remarkably reduced, and discomfort of intubation is avoided; besides, the ultrasonic probe is not influenced by a gas medium, the sound energy attenuation is small, and the detection depth and the image resolution are improved; therefore, operation center packet detection can be carried out in real time, and operation safety is improved.

Description

technical field [0001] The present application belongs to the technical field of structural heart disease treatment equipment, and more specifically relates to a two-dimensional ultrasound imaging catheter in a cardiac cavity and a system thereof. Background technique [0002] Structural heart disease (SHD) is the fastest growing field in the field of cardiovascular intervention in recent years. With the continuous emergence and promotion of new technologies for the treatment of structural heart disease around the world, the concept of structural heart disease has gradually become well known by cardiology, other specialties, and the general public. Structural heart disease refers to any disease related to the heart and the large blood vessel structure adjacent to the heart other than electrocardiographic disease and coronary artery disease, which is characterized by correcting or changing the structure of the heart to treat the disease. Specific disease categories include: ...
