What is a monopolar resectoscope?
Monopolar resectoscope In a monopolar system, the electrons flows from a electrosurgery generator to active electrode (electrode of the loop). From the electrode, the current flow is transmitted to tissue then to the plate (neutral electrode) and returns to generator.
What is monopolar used for?
Monopolar electrosurgery can be used for several modalities including cut, blend, desiccation, and fulguration. Using a pencil instrument, the active electrode is placed in the entry site and can be used to cut tissue and coagulate bleeding.
What does monopolar mean?
Having a single pole
monopolar (not comparable) Having a single pole. Using a single electrode.
What does monopolar mean in medical terms?
1. Having one pole. Synonym: unipolar. 2. In therapeutic electrical stimulation, the application of a current using large dispersive electrodes and smaller active electrodes under which the treatment effects occur.
How does a resectoscope work?
A thin, tube-like instrument used to remove tissue from inside the body. A resectoscope has a light and a lens for viewing. It also has a tool that uses an electric current to cut, remove, or destroy tissue and control bleeding. In men, a resectoscope is inserted through the urethra into the bladder or prostate.
What is monopolar electrocautery?
monopolar electrocautery (unipolar electrocautery) an electrocautery in which current is applied through a handheld active electrode and travels back to the generator through an inactive electrode attached to the patient (the grounding pad), so that the patient is part of the electrical circuit.
What is monopolar radiofrequency?
Monopolar radiofrequency (RF) is a nonsurgical approach to skin tightening and photorejuvenation. The FDA first cleared its use for treatment of periorbital rhytids in 2002. Additional clearances were given for tightening of the lower face in 2004 and for skin tightening on the body in 2005.
What is the size of a resectoscope?
Resectoscope diameter was 24 F in group 1 (n=35) or 26 F in group 2 (n=36). Urethral catheter type, catheter removal time and energy type were kept constant for all patients.
What is the diameter of a resectoscope?
Equipment. The TEM rectoscope is 40 mm in diameter and is either 12 or 20 cm in length. At the surgeon’s end, the rectoscope is sealed with a gastight, removable facepiece. This has four ports, one for the magnifying stereoscopic optic and three for instruments (Figure 166-1).
What does unipolar mean in medical terms?
Unipolar depression is another name for major depressive disorder. The term “unipolar” means that this form of depression does not cycle through other mental states, such as mania. In contrast, bipolar conditions cause periods of both depression and mania.
What is the difference between monopolar and bipolar radiofrequency?
The monopolar type uses a single electrode tip, which delivers energy to the space between the electrode and the grounding plate. The bipolar type passes electrical current between the two electrodes applied to the skin.
What is a monopolar probe?
The Monopolar Probe is a single stimulating electrode used for coarse stimulation, such as stimulation of a tumor mass. Used in conjunction with a separate return needle electrode.
