n. the use of a high-frequency electric current from a fine wire electrode (a *diathermy knife) to cut tissue. The ground electrode is a large metal plate. When used correctly, little heat spreads to the surrounding tissues, in contrast to *electrocautery.
n. the production of heat in a part of the body by means of a high-frequency electric current passed between two electrodes. Diathermy is utilized to coagulate tissues and seal off blood vessels, thus effecting *haemostasis. In bipolar diathermy electric current passes between the two electrodes of the instrument. In monopolar diathermy the instrument is one electrode, the other being a large pad applied to another part of the patient’s body. Examples of instruments used to deliver diathermy include diathermy knives, forceps, and scissors. Diathermy snares and needles can be used to destroy unwanted tissue and to remove small superficial neoplasms. See also electrosurgery.... diathermy
(TCRE) an operation, which is performed under local anaesthetic, in which the membrane lining the uterus (see endometrium) is cut away by a form of *electrosurgery using a *resectoscope, which is introduced through the cervix. Like *endometrial ablation, TCRE is used as an alternative to hysterectomy to treat abnormally heavy menstrual bleeding as it results in fewer complications and shorter stays in hospital.... transcervical resection of the endometrium
