What is an Ellman unit?
Ellman Radio Frequency Ellman RF units are universally considered as the gold standard in radio frequency surgery, and are being continually researched and revised to provide the best in advanced surgical unit. At 4MHz, thermal tissue alteration is limited to within 20 microns of the surgical site.
What is an Ellman Surgitron?
Background: The Ellman Surgitron is a new electrosurgical device with high frequencies (4 MHz) for special use in oculoplastic surgery. Four different operational functions are available: (1) cutting with minimal coagulation, (2) combined cutting and coagulation, (3) coagulation and (4) fulguration.
How does the RF work in electrosurgical unit?
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 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 a cautery device?
The electrocautery unit (Bovie, cautery, or electrosurgical unit) (Figure 23-35, A) uses high-frequency electrical energy to cut tissue or coagulate bleeding. The preferential conduction of electrical energy by blood vessels facilitates coagulation.
What is electrocautery machine?
Electrocautery. The electrocautery unit (Bovie, cautery, or electrosurgical unit) (Figure 23-35, A) uses high-frequency electrical energy to cut tissue or coagulate bleeding. The preferential conduction of electrical energy by blood vessels facilitates coagulation.
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.
Does a Hyfrecator hurt?
HYFRECATOR FAQS Is Diathermy treatment painful? The treatment is generally tolerated well. Whilst there is some slight discomfort, the treatment is very quick and the specific treatment areas are only very small.
Is Hyfrecator an electrocautery?
The hyfrecator has a large number of uses, such as removal of warts, pearly penile papules, desiccation of sebaceous gland disorders, electrocautery of bleeding, epilation, destruction of small cosmetically unwanted superficial veins, in certain types of plastic surgery and many other dermatological tasks.
What is spray coagulation?
Spray coagulation cauterises the. tissue by deliberately generating long sparks between. the tip of the active electrode and the tissue (Figure 3). With this coagulation method, the electrode and the. tissue do not come into direct contact and thus.
What is suction cautery?
Suction cautery wands are covered by a polypore lining. Monopolar current is directed from the suction cautery tip to the surgical site. Suction removes surgical plume and char debris to create an efficient device for extirpating adenoid tissue.
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 [1].
What is coagulation in ESU?
Coagulation: blood tamponade or destruction of the tissue without cut effect. Fulguration: it is caused by using electrical arcs (sparks) which jump from the active electrode to the tissue through the air pocket. Biophysical effects of electro-surgical current.
What is RF in dermatology?
Objective: Radiofrequency (RF) is novel nonablative technology originally used to target photodamage. It differs from lasers in that it uses an electric current rather than a light source. It is frequently used in dermatology to treat skin laxity, rhytides, acne vulgaris and scarring, and cellulite.
Does a Hyfrecator leave scars?
Unlike other methods available, the Hyfrecator causes no scarring and incurs minimal downtime after your procedure. Your Certified Laser Technician will discuss the proper post care to keep your treatment area clear and healthy and to prevent future occurrences.
Can you use a Hyfrecator with a pacemaker?
Conclusion: Hyfrecators are safe to use in patients with defibrillators and can be used in pacemaker patients within 2 inches of the device perimeter.
Is Hyfrecator a monopolar?
The Hyfrecator offers both monopolar and bipolar modes of operation. In monopolar procedures, the Hyfrecator offers two power settings to assist with fine power control.
What is a suction coagulator?
Suction Coagulators provide controlled fluid evacuation and facilitate precise electrosurgical coagulation procedures independently or simultaneously. Designed to provide controlled fluid evacuation. Facilitates precise electrosurgical coagulation procedures.
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.
