Mechanical focused ultrasound treatment head

Abstract

The invention discloses a mechanical focused ultrasound treatment head. According to the invention, a diagnosis shell and a treatment shell are fixed through a positioning column and a positioning hole to form a diagnosis and treatment integrated device. The diagnosis and treatment integrated device is provided with a window; a driving motor is arranged on the inner upper portion of the diagnosisand treatment integrated device; the output end of the driving motor is provided with a driving device; the lower end of the driving device is provided with a mechanical arm assembly; the part, on oneside of the driving device, of the diagnosis and treatment integrated device is provided with an ascending limiter and a descending limiter; and a first fixed base and a second fixed base are each provided with a treatment wafer. A mechanical arm part can be driven to move through the driving motor and the driving device, so ultrasonic beams emitted by the treatment wafers are focused on one axis, and a focus can move within a certain range on the axis of ultrasonic waves; and thus, the mechanical focused ultrasound treatment head is high in applicability and can push calculi within a large range. As the mechanical focused ultrasound treatment head and a diagnosis probe are bound together, a finished B-ultrasound scanner can be directly utilized after combination, and a new treatment device can be formed without any change.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a mechanical focused ultrasonic therapy head. Background technique [0002] "Focused Ultrasound Therapy" is an emerging non-invasive technology. The basic principle of this technology is to focus the low-energy ultrasonic waves emitted by external ultrasonic sources in the living body through a certain focusing method, and form a high-intensity ultrasonic wave in the tissue. The region, that is, the focal region, enables the local tissue located in the focal region to reach a high temperature of 65-100°C in an instant. At the same time, combined with the combined effects of ultrasonic cavitation effect, mechanical effect, thermal effect, and immune effect, it leads to instantaneous coagulation necrosis of the tissue. , without significant damage to the surrounding tissue, and the coagulation necrotic tissue can be gradually absorbed or scarred. By performing solidification treatm...

AI Technical Summary

Problems solved by technology

[0003] In the process of focused ultrasound treatment, the key factors affecting the treatment effect are the accuracy, safety and effectiveness of focus positioning. Therefore, accurate positioning and real-time monitoring of the target area are very important to ensure that the treatment energy can accurately reach the target area tissue and avoid The adjacent normal tissue is damaged, and the existing mechanical focused ultrasound therapy probe still has the problem of inaccuracy in the focus positioning process, and the focus cannot be moved in the axial direction after the focus is determined, resulting in low applicability. Therefore, the present invention proposes a Mechanical focused ultrasound treatment head to solve the deficiencies in the prior art
