Electrosurgical Unit
These are the 3 components of the monopolar ESU.
What are the generator, active electrode, grounding/dispersive pad.
This alternative energy/tool uses mechanical vibrations to cut and coagulate tissues. Produces less charring, no plume, and does not need a grounding pad.
What is ultrasonic energy OR ultrasonic scalpel.
This is a type of laser used in surgical procedures. 1 bonus point to the first person who can name 3.
What is argon, CO2, diode, krypton, Nd:YAG, tunable dye.
Name one laser safety precaution.
Post laser signs on OR doors, wear protective eyewear, do not use flammable solutions, have a basin of sterile water, etc.
This technology allows for at the end of a case, a mat is activated, and a wand is passed over the operative site to detect any missing sponges.
What is radio-frequency identification (RFID).
This mode of the ESU is used for delicate surgical procedures or in patients with implanted pacemakers or metal prostheses.
What is the bipolar ESU.
The acronym "laser" means this.
light amplification by the stimulated emission of radiation.
Frequently used for soft tissue ablation in various treatment including dental applications or treatment of vascular lesions.
What is the diode laser.
A laser is named for the active medium it uses. 1 bonus point to the first person who can name them all.
What is gas, solid, liquid, and semiconductor crystals.
These are used to catalogue information on chemicals and solutions used in the HCF.
What are Safety Data Sheets (SDS)
This type of coagulation may be used to cauterize large areas of tissue for debridement and debulking, and to achieve hemostasis.
What is argon plasma coagulation.
This is one type of the four interactions laser has with tissue. 1 bonus point to the first person who can name them all.
What are absorption, transmission, reflection and scattering.
An advantage of this type of laser is that the beams can be transmitted through clear fluids. 1 bonus point to the first person who name the procedures they are useful in.
What is the Nd:YAG/Ho:YAG lasers. BONUS: urological and ophthalmological procedures.
This laser is used in shock wave lithotripsy.
What is tunable dye.
Smoke and aerosolized tissue. Formed when tissue is thermally destroyed and vaporized using the ESU, laser, or other surgical devices.
What is tissue plume.
These ESU tips allow charred tissue to be easily removed with a sponge.
What are non-stick Teflon-coated ESU tips.
This is a device that uses high-frequency sound waves that create imploding bubbles to fragment and emulsify tumor tissue and leave vascular structures intact.
What is the CUSA (cavitron ultrasonic surgical aspirator)
This laser is frequently used in cases such as lithotripsy and treatment of benign prostatic hyperplasia.
What is the Ho:YAG laser.
This laser produces a visible blue or green light, so does not need aiming beam. Can travel through clear fluids and tissues, so it is useful in treating diabetic retinopathy.
What is the argon laser.
The dispersive pad should be applied to these types of areas on the body.
What are large, fleshy areas.
This utilizes a combination of bipolar current and plasma technology to create a thin layer of highly ionized particles that vaporize the tissue without having to make direct contact.
What is plasma vaporization.
This lasers laser beam is absorbed less by hemoglobin compared to the argon laser beam, so ophthalmologists are increasingly using this laser to destroy tissue on the retina of the eye.
What is the krypton laser.
These 2 lasers are the instruments of choice for laser bronchoscopy.
