  2. Hyfrecator - Wikipedia

    en.wikipedia.org/wiki/Hyfrecator

    The amount of output power is adjustable, and the device is equipped with different tips, electrodes and forceps, depending on the electrosurgical requirement. Unlike other types of electrosurgery, the hyfrecator does not employ a dispersive electrode pad that is attached to the patient in an area not being treated, and that leads back to the ...

  3. Electrosurgery - Wikipedia

    en.wikipedia.org/wiki/Electrosurgery

    (Note that frequency of the alternating electric current is an inverse of the duration of a single cycle). To minimize the effects of muscle and neural stimulation, electrosurgical equipment typically operates in the radio frequency (RF) range of 100 kHz to 5 MHz.

  4. Medical applications of radio frequency - Wikipedia

    en.wikipedia.org/wiki/Medical_applications_of...

    Diathermy equipment typically operates in the short-wave radio frequency (range 1–100 MHz) or microwave energy (range 434–915 MHz). [citation needed] Pulsed electromagnetic field therapy (PEMF) is a medical treatment that purportedly helps to heal bone tissue reported in a recent NASA study. This method usually employs electromagnetic ...

  5. Diathermy - Wikipedia

    en.wikipedia.org/wiki/Diathermy

    Electrosurgery and surgical diathermy involve the use of high-frequency A.C. electric current in surgery as either a cutting modality, or else to cauterize small blood vessels to stop bleeding. This technique induces localized tissue burning and damage, the zone of which is controlled by the frequency and power of the device.

  6. Harmonic scalpel - Wikipedia

    en.wikipedia.org/wiki/Harmonic_scalpel

    A harmonic scalpel cuts via vibration. The scalpel surface itself cuts through tissue by vibrating in the range of 55,500 Hz. The high frequency vibration of tissue molecules generates stress and friction in tissue, which generates heat and causes protein denaturation.

  7. Surgical instrument - Wikipedia

    en.wikipedia.org/wiki/Surgical_instrument

    Electrosurgery is a modern technology that uses high frequency electrical current to cut or coagulate blood. [23] Argon plasma coagulation involves the application of gas discharges in argon. [24] Ultrasound surgery uses high frequency and high energy sound waves to target and destroy tissue. [25]

  8. Cauterization - Wikipedia

    en.wikipedia.org/wiki/Cauterization

    Cauterization (or cauterisation, or cautery) is a medical practice or technique of burning a part of a body to remove or close off a part of it. It destroys some tissue in an attempt to mitigate bleeding and damage, remove an undesired growth, or minimize other potential medical harm, such as infections when antibiotics are unavailable.

  9. High-frequency vibrating screens - Wikipedia

    en.wikipedia.org/wiki/High-frequency_vibrating...

    Its high-frequency characteristics differentiate it from a normal vibrating screen. High-frequency vibrating screens usually operate at an inclined angle, traditionally varying between 0° and 25° and can go up to a maximum of 45°. They should operate with a low stroke and have a frequency ranging from 1500 to 9000 RPM. Frequency in High ...
