Electrosurgical electrodes
Deviceinformed.com is an online catalog of medical equipment from worldwide famous suppliers and companies. Our medical devices database provides information about leading medical device manufacturers from all over the world who offer a wide range of medical tools for various fields of medicine. The products in our catalog are of high-quality standards and designed for easy daily use. This category contains information about electrosurgical electrodes.
Electrosurgical electrodes are used during electrosurgery. They use high-frequency current in order to cut, coagulate, fulgurate the tissue. These devices are commonly used during surgical procedures helping to make accurate cuts and prevent huge blood loss in hospital operating rooms.
There are two different types of electrosurgery: bipolar and monopolar.
1) Monopolar electrosurgery can be used for a blend, cut, desiccation, and fulguration. The electrode is placed in the open surgical area and is used to cut the tissue and coagulate the bleeding. The return pad is attached to the patient, that the current flows from the generator will return back to it.
2) Bipolar electrosurgery uses low-frequency voltages and is used in procedures, where forceps electrodes grab tissues on both sides. The current of the tissue is limited to the arms of the forceps electrode.
Electrosurgical electrodes can be used in different methods:
• In the cutting method, the electrosurgical electrode touches the tissue and the high-frequency current vaporizes its water content. Using this method, often the electrodes feature finer wire or wire loop.
• Electrosurgical desiccation uses the application of touching the tissue that is open to air and the generated current is lower than required for cutting. This technique treats nodules under the skin and provides minimal damage to the skin area.
• In fulguration mode, the electrosurgical electrode is kept away from the tissue in order that arc discharge will develop between the air gap and the ionized tissue. This method is used for superficial lesions like skin tags or ionization.
Electrosurgical electrodes are designed to deliver clear cutting performance during various surgical procedures. These devices prevent unintended skin burns, current from passing selectively through metal, and provide precise control over bleeding during complicated surgeries. Electrodes are available in various types, lengths and shaft sizes. Physicians can use them few times because they are made of stainless steel and can be easily sterilized.
