Does focused ultrasound therapy hurt?

Ultrasonic focused therapy technology has a very good effect in the treatment of many diseases in clinical practice. However, due to the characteristics of this technology, a high-temperature treatment point of 70℃ to 100℃ will be formed on the tumor. Therefore, the most direct feeling is that it will cause severe pain. It is normal for patients who do not understand the situation to have such concerns. So, is focused ultrasound therapy painful? Is the pain obvious?

Traumatic stimulation can cause a painful sensation that can radiate to the lower abdomen. Ultrasonic focusing uses ultrasound as energy. Many beams of ultrasound are emitted from outside the body into the body, and during the transmission process, they are focused on one point, the tumor. Through the conversion of sound waves and heat energy, a high-temperature treatment point of 70℃ to 100℃ is formed within 0.5 to 1 second. This high-temperature point is like a scalpel cutting the tumor, and no tumor in the focal area is spared. The focused ultrasound knife causes coagulative necrosis of tumor tissue, which loses its ability to proliferate, infiltrate and metastasize. The principle of this machine is similar to that of a solar cooker, which concentrates sunlight at a focal point to generate huge energy.

Treatment Principle

The focused ultrasound system has good tissue penetration and positioning capabilities. It can transmit energy through the surface tissue and focus it on the target tissue at a specific depth, producing a biological effect and allowing the diseased tissue to recover quickly. The dose of focused ultrasound therapy is easy to control and has high safety. After treatment, only the local tissue will have transient congestion and edema, the surface cells can remain intact, and recovery is fast after surgery.

Ultrasound focusing has good tissue penetration and energy storage. The host generates high-frequency electrical signals, which are converted into focused ultrasonic waves through the transducer, and the ultrasonic waves are transmitted to the diseased tissue using a circulating water system, a sound-transmitting membrane and a contact coupling agent. When ultrasound is in biological tissue, it will produce thermal effect, mechanical effect, cavitation effect and the biochemical effect induced by it. Haijixing uses these characteristics to act on the diseased tissue to cause the diseased tissue to degenerate, promote tissue reconstruction and improve microcirculation to achieve the treatment goal.
