Electrocautery for dissecting through the liver capsule and parenchyma.


Electrocautery is a surgical technique which involves introducing high frequency current to a specific area of the body in order to remove unwanted tissue, seal off blood vessels, or to create a surgical incision. Many surgeons use electrocautery instruments, under the belief that electrocautery is cleaner, safer, and more efficient than many of the alternatives. If you've ever watched a medical drama, you have probably seen electrocautery in action.

The instrument used to perform electrocautery is also known as an electrocautery. An electrocautery uses a very high frequency, usually upwards of 100 kHz, to ensure that the patient's nerves and muscles are not stimulated. Lower frequencies could cause twitching and cramps, which would be a serious problem. Depending on the voltage used, the electrocautery can have varying effects on the patient's body. [1]
