Electrosurgical Devices for Cutting and Coagulating Tissue
Electrosurgical units (ESU), also known as diathermy machines or high-frequency surgery units, utilise the effect that high-frequency alternating current has on the tissue. High-frequency surgery usually uses frequencies between 300 kHz and 4 MHz, as currents in this frequency range create a thermal effect in the tissue that can be used in medicine for cutting and coagulation. The thermal effect is caused by the conversion of electrical energy into thermal energy.
To efficiently use this effect, the electrosurgical unit is connected to special electrosurgical electrodes. Depending on the type of application, these electrodes differ in shape and size. A distinction can be made, for example, between ball electrodes, needle electrodes and loop electrodes.
Cutting with Electrosurgery Units
The cutting of tissue with a surgical diathermy machine is based on the rapid heating of the tissue fluid and the resulting explosive vapour pressure, which causes the cell walls and the tissue to tear apart. Cutting with an electrosurgical device offers many advantages; it prevents bleeding and germ transfer, and the tissue is mechanically protected.
Coagulation with the Diathermy Machine
During coagulation, tissue is boiled away, so to speak. The slow heating causes the tissue to shrink and the existing tissue fluid to thicken or evaporate. This effect comes in handy when closing smaller vessels during surgical procedures and is particularly effective when treating spider veins and haemangiomas.
Monopolar Technique
The monopolar technique requires two electrodes: a large neutral electrode and an active electrode with a very small contact area. The current flows through the active electrode into the body, creating the desired thermal effect at the target site. The large neutral electrode returns the current from the patient without causing burns due to its low current density.
Bipolar Technique
The bipolar technique does not require a separate neutral electrode. In this method, the instrument connected to the electrosurgical unit combines the active and neutral electrodes. For example, in a bipolar forceps, one arm acts as the active electrode and the other as the neutral electrode. The current thus flows only within the treated tissue, offering precise control. This technique is especially preferred for delicate neurological procedures.
Difference Between Cauteries and Electrosurgical Units
Unlike an electrosurgical unit, where alternating current generates heat in the tissue through electrical resistance, a cautery is directly heated using direct current. The heat is transferred to the tissue via the cautery tip, and no current passes through the tissue. This technique is now only used when any current flow through the body must be avoided.
