High-strength focusing ultrasonic therapeutic apparatus

Abstract

The invention discloses a high-strength focusing ultrasonic therapeutic apparatus, which comprises a combined therapeutic head, an ultrasonic transmitting / receiving host machine, a five-DOF (Degree of Freedom) mechanical arm and a work station, wherein the combined therapeutic head comprises a B-ultrasonic probe and a group of therapeutic probes which are relatively accurately fixed in positions; the combined therapeutic head is connected with the five-DOF mechanical arm; and the work station controls the five-DOF mechanical arm and the ultrasonic transmitting / receiving host machine to work respectively. During the therapeutic process, phase image scanning and adjustment of phase therapeutic position are carried out in an electronic manner, so that two-dimensional B-ultrasonic image cross section is effectively overlapped with high-power ultrasonic beam therapeutic cross section, the accuracy and reliability of therapy and real-time observation are ensured, and the five-DOF mechanical arm is accurate to position and flexible to control; the scan image is more intuitive and clear through three-dimensional reconstruction so as to facilitate subsequent observation and diagnosis; and the therapeutic apparatus is particularly suitable for carrying out noninvasive high-strength focusing ultrasonic therapy on pathological tissues of organs such as glandula mammaria, liver, kidney, uterus, anteprostate and the like.

Description

technical field [0001] The invention relates to a medical instrument, in particular to a high-intensity focused ultrasonic treatment instrument for treating tumors with ultrasonic waves, and belongs to the field of medical instruments. Background technique [0002] "High-intensity focused ultrasound therapy" is an emerging non-invasive technology for tumors. The basic principle of this technology is: through a certain focusing method, the low-energy ultrasonic waves emitted by the external ultrasonic source are focused on the living body, and a region with high sound intensity is formed in the tissue, that is, the focal region, so that the local area located in the focal region The tissue can reach a high temperature of 65-100°C in an instant. At the same time, combined with the cavitation effect, mechanical effect, thermal effect, and immune effect of ultrasonic waves, it will cause instantaneous coagulation necrosis of the tissue without significant damage to the surroundi...

Problems solved by technology

However, the cost of real-time monitoring using MRI imaging is very high, and the magnetic field stability requirements for MRI imaging are relatively high. Ultrasound therapy equipment needs to be designed without magnetization, which brings great difficulty to system integration.
