What is the frequency range of currents used in surgical diathermy units?
Surgical diathermy involves current frequencies in the range of 400 KHz to 10 MHz. Currents up to 500 MA may then be safely passed through the patient. Diathermy may be either monopolar or bipolar.
What is surgical diathermy equipment?
The surgical diathermy performs its function by the application of high density radio frequency current which can be used to cut or coagulate tissue. Its improper lIse can result in electrical burns and even electrocution.
What is electric surgical unit?
An electrosurgical unit is a device that uses high-frequency (HF) electrical currents to cut or coagulate tissue during surgery, known as electrosurgery. It consists of an electrosurgical generator that transforms electrical energy into HF current. It is operated using a specific control.
What is a surgical diathermy used for?
Introduction. Diathermy is the use of high frequency alternate polarity radio-wave electrical current to cut or coagulate tissue during surgery. It allows for precise incisions to be made with limited blood loss and is now used in nearly all surgical disciplines.
When do we use Fulguration?
A procedure that uses heat from an electric current to destroy abnormal tissue, such as a tumor or other lesion. It may also be used to control bleeding during surgery or after an injury. The electric current passes through an electrode that is placed on or near the tissue.
What are the types of diathermy?
There are three main types of diathermy: shortwave, microwave, and ultrasound.
- Shortwave. Shortwave diathermy uses high-frequency electromagnetic energy to generate heat.
- Microwave. Microwave diathermy uses microwaves to generate heat in the body.
- Ultrasound. Ultrasound diathermy uses sound waves to treat deep tissues.
Is diathermy the same as cautery?
The word cautery originates from the latin, meaning to brand. It relates to the coagulation or destruction of tissue by heat or a caustic substance. Electrosurgery (particularly electrocoagulation) is sometimes incorrectly called diathermy, which means ‘dielectrical heat’.
Is Bovie monopolar or bipolar?
Monopolar electrosurgery is the most commonly used because of its versatility and effectiveness. The Bovie line of electrosurgery generators provides the surgeon with a range of applications to meet the particular needs of your practice and makes use of both Bipolar and Monopolar modes.
What is surgical Fulguration?
Listen to pronunciation. (ful-guh-RAY-shun) A procedure that uses heat from an electric current to destroy abnormal tissue, such as a tumor or other lesion. It may also be used to control bleeding during surgery or after an injury.
What can diathermy be used for?
Diathermy is commonly used for muscle relaxation , and to induce deep heating in tissue for therapeutic purposes in medicine. It is used in physical therapy to deliver moderate heat directly to pathologic lesions in the deeper tissues of the body.
What are the side effects of diathermy?
This includes blisters, bruising, burning or abnormal feeling, change in color, swelling, redness, pain, itching, peeling, flaking, or pimples. Most of the time, these skin reactions go away within a few minutes to hours. Call your doctor if any of these effects are very bad, bother you, or do not go away.
How does diathermy work?
Diathermy uses high-frequency electric current to produce heat deep inside a targeted tissue. It can reach areas as deep as two inches beneath the skin’s surface. The diathermy machine does not apply heat directly to the body. Instead, the waves generated by the machine allow the body to generate heat from within…
