Problems solved by technology

But its disadvantages are: B-ultrasound imaging is only an image on a plane, which is not enough to reflect the effect of the focal point on the diseased tissue during the entire treatment process, and it is not conducive to the use of B-ultrasound images for positioning

Abstract

A 3-D locating system for high-intensity focused ultrasonic operation is composed of a 3-D moving bed fixed on the floor, a machine frame arranged at outside of longitudinal central line of the said bed, a C-shaped arm mechanism on the machine frame, and a treating head assemblage containing a set of precise location system and ultrasonography-B imaging mechanism so as to realize functions of monitoring and regulating real-time location while treating.

Description

technical field [0001] The invention relates to a stereotaxic system, in particular to a stereotaxic system in high-intensity focused ultrasound surgery, and belongs to the field of medical devices. Background technique [0002] High-intensity focused ultrasound surgery is a recent research hotspot in the field of non-destructive surgery. Its principle is: through a certain method, the ultrasonic waves emitted by the external transducer are focused on a relatively small focal area in the body, and the energy in this area is relatively concentrated. In about 1 second, the temperature of human tissue is rapidly raised to above 70°C; diseases are treated through this high-temperature focus. The stereotaxic system is an essential part of high-intensity focused ultrasound surgery. It can align the diseased part of the patient with the functional modules of ultrasound therapy, and move during the treatment, so that the function of the patient and ultrasound therapy The relative p...
