What is the purpose of electrosurgery?
Electrosurgery is used routinely in eye surgery to cut, coagulate, dissect, fulgurate, ablate and shrink tissue. High frequency (100 kilohertz to 5 megahertz), alternating electric current at various voltages (200–10,000 Volts) is passed through tissue to generate heat.
What is the principle of electrocautery?
Electrocautery, also known as thermal cautery, refers to a process in which a direct or alternating current is passed through a resistant metal wire electrode, generating heat. The heated electrode is then applied to living tissue to achieve hemostasis or varying degrees of tissue destruction.
What is meant by electrocautery?
Listen to pronunciation. (ee-LEK-troh-KAW-teh-ree) A procedure that uses heat from an electric current to destroy abnormal tissue, such as a tumor or other lesion.
What is the working principle of electrosurgical cautery?
The electrosurgical unit is the source of the voltage. Electrical energy is converted to heat in tissue as the tissue resists the flow of current from the electrode. Three tissue effects are possible with today’s electrosurgical units—cutting, desiccation, and fulguration.
What are the 2 types of electrosurgery?
Electrosurgery is a term used to describe multiple modalities that use electricity to cause thermal destruction of tissue through dehydration, coagulation, or vaporization. The two types of electrosurgery most commonly used are high-frequency electrosurgery and electrocautery.
What is the difference between bipolar and monopolar?
There is one basic difference between bipolar and monopolar techniques. With monopolar electrosurgery, a probe electrode is used to apply the electrosurgical energy to the target tissue to achieve the desired surgical effect. With the bipolar electrosurgical method a bipolar device, often a set of forceps, is used.
What are 3 uses for electrosurgery Fulguration?
The purposes of electrosurgery are to destroy benign and malignant lesions, control bleeding, and cut or excise tissue. The major modalities in electrosurgery are electrodesiccation, fulguration, electrocoagulation, and electrosection.
Is electrocautery a surgery?
What is electrocauterization? Electrocauterization is a routine surgical procedure. A surgeon or doctor uses electricity to heat tissue in order to: prevent or stop bleeding after an injury or during surgery.
How long does electrocautery take to heal?
After surgery you may have some pain, swelling, and redness. Healing usually occurs within 2 to 4 weeks. Healing time may be prolonged if a large area of tissue is burned. Scarring may occur.
How does electrocautery remove skin tags?
Killing the Tag With Heat A skin tag can be removed with intense heat as well. This removal uses an electrocautery tool that heats a needle until it can burn through the stalk of the tag. The heat from the needle closes the wound so there is very little bleeding when a skin tag is removed using this method.
Which is a type of electrosurgery?
The two types of electrosurgery most commonly used are high-frequency electrosurgery and electrocautery. High-frequency electrosurgery refers to four different methods: electrocoagulation, electrodesiccation, electrofulguration, and electrosection.
What is the common known term for bipolar disorder?
Bipolar disorder, formerly called manic depression, is a mental health condition that causes extreme mood swings that include emotional highs (mania or hypomania) and lows (depression).
What do you need to know about electrosurgery?
Electrosurgery: part I. Basics and principles The term electrosurgery (also called radiofrequency surgery) refers to the passage of high-frequency alternating electrical current through the tissue in order to achieve a specific surgical effect. Although the mechanism behind electrosurgery is not completely understood, heat production and therma …
What’s the difference between electrosurgery and direct current?
Often “electrocautery” is used to describe electrosurgery. This is incorrect. Electrocautery refers to direct current (electrons flowing in one direction) whereas electrosurgery uses alternating current. During electrocautery, current does not enter the patient’s body. Only the heated wire comes in contact with tissue.
Why is electrosurgery a common cause of litigation?
Not surprisingly, electrosurgery is one of the most common causes of litigation.50,51 A bipolar circuit functions with the circuit traveling between two electrodes placed close together and the current traveling in the tissue between the electrodes. In this case, a grounding pad is not necessary.
How is electrosurgery used to treat the gut?
“Electrosurgery” provides both cutting and coagulation, making it the ideal technology for producing therapeutic coagulation, resection, and tissue ablation throughout the gut. When the current density is sufficient within the targeted tissue, cellular water is rapidly heated, resulting in boiling and bursting of cellular membranes.
