dilatators

Dilatators are medical instruments used to widen or stretch a body passage or opening. They come in various shapes, sizes, and materials, often made of metal or silicone. The design of a dilatator is typically tapered, allowing for gradual insertion and expansion of the tissue.

These devices are employed in a range of medical procedures. In gynecology, they might be used to dilate the cervix for diagnostic or therapeutic reasons, such as during an abortion or for the insertion of an intrauterine device. In urology, dilatators can be used to widen the urethra, for example, to relieve blockages or to facilitate endoscopic examinations. They are also used in other specialties, such as gastroenterology for dilating the esophagus or anal canal.

The use of dilatators requires careful technique to avoid injury to the surrounding tissues. Lubrication is often applied to ease insertion and minimize discomfort. The process is usually performed under sterile conditions to prevent infection. While the term "dilatator" can refer to a range of instruments, the core function remains the controlled widening of a physiological opening for medical purposes.
