Final answer:
A high frequency machine produces rapid oscillations within glass electrodes for therapeutic treatments and surgeries, using high-frequency sound waves or electrical oscillations for precision and minimal tissue damage.
Step-by-step explanation:
A high frequency machine produces a high rate of oscillation within glass electrodes for facial and scalp treatments. This technique is closely related to the use of ultrasound in medical settings. Ultrasound devices utilize high-frequency sound waves to create images or treat tissues. In therapeutic applications, high-intensity ultrasound can be converted into thermal energy for deep-heat treatments, such as ultrasound diathermy, which commonly employs frequencies of 0.8 to 1 MHz. During surgical procedures, such as those involving electric scalpels, these devices typically operate at high frequencies to cut through tissue with minimal damage, making use of the properties of electric fields at sharp edges. The high rate of oscillation at frequencies such as 23 kHz can cause the tissue to be pulverized upon contact with the probe, enhancing precision and reducing trauma during surgery.
