What are bipolar forceps used for?
The bipolar forceps securely grasp tissue, precisely dissect, and are able to effectively coagulate small as well as very large blood vessels (2 mm to 20 mm), alleviating the need for surgical clips or staples.
When is bipolar cautery used?
Bipolar electrosurgery uses lower voltages so less energy is required. But, because it has limited ability to cut and coagulate large bleeding areas, it is more ideally used for those procedures where tissues can be easily grabbed on both sides by the forceps electrode.
Why saline is used in bipolar cautery?
Recent trials evaluating the safety and efficacy of bipolar resectoscopes have claimed advantages over standard monopolar resection (3-7). By using physiologic saline (0.9% NaCl) as irrigation fluid, it eliminates any danger of TUR syndrome and thus eliminates the conventional time limit of resection.
What are cowhorn forceps used for?
Furcation-pattern forceps (often referred to as “cowhorns”) have long been favored in oral surgery for the extraction of lower molars with ordinary root-anatomy.
Why is it called bayonet forceps?
Forceps made with bayonet tips are often named for the functions they are intended to perform. Bayonet dressing forceps are made with serrated edges and are used to grasp and remove sterile dressings from wounds.
What is difference between cutting and coagulation?
The cutting mode focuses heat at the surgical site, using sparks being the more focussed way to distribute heat; the cutting mode should therefore be used with the tip slightly away from the tissue. Coagulation alternatively uses a pulsed waveform with a high voltage.
What is a Cryer elevator used for?
Cryer elevators can luxate a mandibular molar distal root after the coronal aspect of septum bone is removed in order to expose the mesial surface of the distal root. The Cryer elevator tip is placed on the exposed mesial root surface to luxate the root along a distal-radial path of least resistance3,7.
What is bipolar stimulation?
In bipolar stimulation, a current is passed between two electrodes, both located near the neural tissue being targeted. More advanced stimulation mode is known as multipolar or phased array mode. Finally, the chapter provides the processes of metabolic and electrochemical stress.
How can you tell a right and left Cryer elevator?
Cryer Right – works on wheel and axle principle….RULES OF ELEVATORS USAGE:
- Palm grip.
- Don’t use the neighbouring tooth as fulcrum.
- Don’t use the buccal or lingual plate of bone as fulcrum.
- Use the left hand for reflection , guard and support.
- Follow root curvature during extraction.
What is the difference between Luxator and elevator?
A luxator is made of softer steel than an elevator, and is not designed to bear rotational forces; it is used as a wedge rather than a first-class or wheel-and-axle lever. Therefore, in a nonsurgical extraction, the luxator is always used parallel to the root surface of the tooth.
