What is a Bovie instrument?
Electrosurgical Units The electrosurgical unit, or Bovie, is a surgical device used to incise tissue, destroy tissue through desiccation, and to control bleeding (hemostasis) by causing the coagulation of blood.
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.
Who invented the Bovie?
By the late nineteenth century, as technology advanced, heat could be produced by electric current. In 1920 William T. Bovie, an eccentric inventor with a doctorate in plant physiology, developed an innovative electrosurgical unit that Harvey Cushing, the founder of modern neurosurgery, introduced to clinical practice.
What is difference between bipolar and monopolar?
For example, bipolar electrosurgery typically involves lower voltage (requiring less energy) and is targeted toward smaller areas. Monopolar electrosurgery is versatile, with modalities including cut, blend, desiccation, and fulguration, and is effective for large areas.
What is the difference between cut and coagulation?
Using a constant waveform, like “cut,” the surgeon is able to vaporize or cut tissue. This waveform produces heat very rapidly. Using an intermittent waveform, like “coagulation,” causes the generator to modify the waveform so that the duty cycle (“on” time) is reduced. This interrupted waveform will produce less heat.
What is bipolar and monopolar?
In monopolar action, the electrical current oscillates between the surgeon’s electrode, through the patient’s body, until it meets the ‘grounding plate’ (typically positioned underneath the patient’s leg) to complete the circuit. In bipolar diathermy, the two electrodes are found on the instrument itself.
What is the frequency of electrosurgery?
Electrosurgical units (ESUs) used in operating rooms convert standard electrical frequencies from the wall outlet, which are 50 to 60 Hz, to much higher frequencies, 500,000 to 3,000,000 Hz .

What is the difference between cut and COAG?
Cut/Coag Most wet field electrosurgical systems operate in two modes: “Cut” causes a small area of tissue to be vaporized, and “Coag” causes the tissue to “dry” (in the sense of bleeding being stopped).
Which is better monopolar or bipolar?
Bipolar applicators better control and distribute energy between electrodes and offer the improved ability to target more specific dermal structures for improved efficacy, compared to monopolar and unipolar devices.
What is RF 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.
What is difference between unipolar and bipolar?
The main difference between the two is that depression is unipolar, meaning that there are no periods of abnormally elevated mood, while bipolar disorder includes symptoms of mania. In a recent article for PsychCentral, Sonya Matejko explored the distinction between the two conditions.
