ARNOTTIS DILATOR Meaning and
Definition
-
Arnottis dilator refers to a medical device used to dilate or enlarge an anatomical structure, particularly blood vessels or urethral strictures. It is named after John A. Arnott, a Scottish surgeon who introduced this device in the 19th century.
The Arnottis dilator is primarily used in the treatment of urethral strictures, which are narrowings or blockages in the urethra, the tube that carries urine from the bladder to the outside of the body. This condition can cause difficulties in urination and lead to other urinary problems. The dilator is a slender, cylindrical instrument typically made of metal or rubber, and it is gently inserted into the narrowed portion of the urethra. By gradually expanding the diameter of the strictured area, the dilator aims to restore normal urine flow and alleviate the symptoms associated with urethral strictures.
In addition to its application in urology, the Arnottis dilator can also be used to dilate blood vessels. In certain medical procedures or conditions, such as the treatment of vascular stenosis or the prevention of ischemic events, the dilator may be utilized to stretch and widen the affected blood vessels. This allows for improved blood circulation and an adequate supply of oxygen and nutrients to the tissues in need.
Overall, the Arnottis dilator is a specialized medical instrument used to dilate strictures in the urethra or blood vessels, aiming to restore regular flow and alleviate related symptoms.
