What is electrosurgery used for?
Electrosurgery is a technique often used in dermatologic surgery to provide superficial or deep coagulation or cutting of the skin. The skin has poor conducting properties for the electrical flow of energy. Therefore, this energy builds up and is converted into heat.
Which radio frequency range is most effective in electrosurgery?
Because nerve and muscle stimulation cease at 100,000 cycles/ second (100 kHz), electrosurgery can be performed safely at “radio” frequencies above 100 kHz. An electrosurgical generator takes 60 cycle current and increases the frequency to over 200,000 cycles per second.
What is a Hyfrecator used for?
A Hyfrecator is a safe form of electrosurgery in which controlled current is used to heat up and destroy tissue. It is a low powered device that works very well for destroying skin tags, red skin spots (cherry angiomas), sun spots (seborrheic keratosis), and a medley of other undesirable skin blemishes.
What is radiofrequency cautery?
The Technique of Radio Frequency involves the passage of high frequency radio waves(2mhz-Megahertz) through soft tissue to cut, coagulate, or remove the tissue.
How is electrosurgery performed?
In electrosurgery, the patient is included in the circuit and current enters the patient’s body. During electrocautery, current does not enter the patient’s body. Instead, current flows through a heating element, which burns the tissue by direct transfer of heat.
Why high-frequency is used in diathermy?
Diathermy is a therapeutic treatment most commonly prescribed for muscle and joint conditions. It uses a high-frequency electric current to stimulate heat generation within body tissues. The heat can help with various processes, including: increasing blood flow.
How does RF electrosurgery work?
Electrosurgery, by contrast, uses radio frequency (RF) alternating current to heat the tissue by RF induced intracellular oscillation of ionized molecules that result in an elevation of intracellular temperature. When the intracellular temperature reaches 60 degrees C, instantaneous cell death occurs.
What is the difference between electrocautery and electrosurgery?
Electrocautery refers to direct current (electrons flowing in one direction) whereas electrosurgery uses alternating current. In electrosurgery, the patient is included in the circuit and current enters the patient’s body.
What is a cautery pen?
Surgical cautery pens–also known as cautery pencils or simply as cauteries–are handheld medical devices used to stop bleeding via heat conducted through the tip.
What is radio frequency mole removal?
Radio Frequency Surgery employs the use of low temperature, high frequency energy radio waves to cauterize and effectively remove growths, without any downtime. It provides results with minimal to no scarring and quick healing.
What is electrosurgical coagulation?
Electrosurgery refers to the cutting and coagulation of tissue using high-frequency electrical current [1]. Physicians using this technique must be knowledgeable about prevention and management of potential complications of electrosurgical procedures.
What is the frequency of an electrosurgical system?
Standard electrical current alternates at a frequency of 60 cycles per second (Hz). Electrosurgical systems could function at this frequency, but because current would be transmitted through body tissue at 60 cycles, excessive neuromuscular stimulation and perhaps electrocution would result.
What can radiofrequency surgery do for your body?
Radiofrequency (RF) surgery—modern electrosurgery—has become a versatile tool for the primary care physician in dermatologic, surgical, and gynecologic applications. It is both time and cost effective, and it provides efficacious treatment for a multitude of lesions.
How is high frequency electrosurgery replacing laser surgery?
High-frequency electrosurgery is now replacing many laser applications because of the minimal tissue damage, low cost of equipment, minimal maintenance, ease of treatment, and excellent long-term results. It has replaced most laser applications for the gynecologic treatment of dysplasia (conization) and condylomata.
How are electrosurgical devices used in surgical procedures?
Electrosurgical devices are frequently used during surgical operations helping to prevent blood loss in hospital operating rooms or in outpatient procedures. In electrosurgical procedures, the tissue is heated by an electric current.
