Application and characteristics of focused ultrasound product

Application and characteristics of focused ultrasound:

The low-frequency concave-convex piezoelectric ceramic transducer has been theoretically and finite-element-analyzed. The transducer has the characteristics of low resonance frequency, small impedance, high emission voltage response, small 360-degree spatial directivity fluctuation and high power. The HIFU piezo ceramic transducer has uniform spatial directivity, high transmission voltage response, good reception characteristics and high power.

Application and characteristics of focused ultrasound:

The medical and cosmetic uses and characteristics of piezoelectric ceramic focusing transducers: Focused ultrasound does not heat the skin surface, nor does it need to be used as a medium value for laser energy transmission through the skin, so it will not affect the skin surface tissue and laser Through the tissues, of course, there will be no excess heat remaining on the skin surface. In this way, the epidermis will not be affected by heat, which can reduce the thermal reaction that is easy to be produced by Orientals, and reduce it more greatly. Focused ultrasound will generate thermal condensation points in the SMAS layer, and thermal effects will diffuse outward from the condensation point, so the heat source is concentrated in the SMAS layer. Can produce more collagen degeneration.

Medical application and characteristics of piezoelectric ceramic focusing transducers:
Ultrasound non-invasive technology has been successfully applied to gynecology such as chronic cervicitis, white lesions of the vulva, and condyloma acuminatum. It has been clinically validated in more than 1,000 domestic hospitals (more than 70% of the top three hospitals) for many years.

principle:

Ultrasound as a non-invasive technique (or non-invasive ultrasound) is a new technology that does not require surgical incision (excision) or destruction of surface tissue (skin, mucous membrane or epithelial tissue), and does not pass through the puncture and deep organization. It can transmit ultrasonic waves emitted from the body through the surface tissue and focus in the deep tissue of the surface tissue to produce a high-energy area, which can make the disease tissue absorb energy and quickly heat up in a short time, and produce a biochemical reaction, which eventually damages the diseased tissue denaturation promotes tissue reconstruction and improvement of microcirculation to recover diseased tissue. The cavitation effect produced by ultrasound can make the cell membrane lose continuity or change its permeability. Because the disease or proliferating tissue is more sensitive to ultrasound, low-energy ultrasound in a specific range can selectively damage the disease tissue cells for therapeutic purposes.

Scope of application

This instrument is suitable for chronic soft tissue injury pain in the neck, shoulder, waist and back of the human body. Chronic soft tissue injury refers to various types of acute trauma or chronic strain and the invasion of wind, cold and dampness, superficial deep fascia, muscles, tendons, tendon sheaths, ligaments, joint capsules, synovial sacs, intervertebral discs, peripheral neurovascular and other tissues. There is or long-term pathological damage. Chronic soft tissue injury is a common disease, and its incidence is second only to cold. The pain caused by patients accounts for more than 50% of the pain outpatients, and the pain is stubborn and easy to repeat. The local can be accompanied by varying degrees of dysfunction, which seriously affects People's daily life and work. With the increasing of age, the incidence rate shows an upward trend, which not only surges among adolescents, but also seriously affects people's work and life; especially for the elderly over 70, the incidence rate is close to 100%, so the impact on humans is getting more and more obvious. The World Health Organization lists chronic soft tissue injury as one of the three most difficult diseases in the world (cancer, cardiovascular and cerebrovascular diseases, chronic soft tissue injury). For the methods of chronic soft tissue injury, there are many methods, such as traditional surgery, microwave, phototherapy, etc., although they all have a certain effect, but each has its own advantages and disadvantages, and it is difficult to achieve satisfactory results.

Using high-intensity focused ultrasound technology (HIFU technology) piezoelectric disc transducers for non-invasive solid tumors. It mainly uses the physical characteristics of ultrasound, such as good tissue penetration and focusability, to accurately focus the countless beams of low-energy ultrasound emitted by the ultrasound transducer on the target tissue in the body. Transient high temperature is generated inside, killing the tumor cells in the target area, so as to "remove" the solid tumor without surgery or bleeding.
