SPECULUM

A speculum is a medical instrument used to hold open a body orifice or cavity to allow inspection or surgical procedures. The most common type of speculum is the vaginal speculum, which is used to hold open the walls of the vagina during gynecological exams or procedures.

Other types of specula include nasal specula, which are used to hold open the nostrils during examination or surgery, and ear specula, which are used to hold open the ear canal during ear exams or procedures.

Specula can be made of various materials, including metal, plastic, or disposable materials. They come in different shapes and sizes, depending on the specific use and the anatomy of the area being examined.

During a procedure, the speculum is inserted into the body orifice and then opened to provide better visibility and access to the area being examined or treated. The speculum is then held in place by a locking mechanism or by the hands of the healthcare provider.

Overall, specula are essential medical instruments used to hold open body orifices and cavities to allow for examination or treatment. They play a critical role in a variety of medical specialties, including gynecology, otolaryngology, and gastroenterology.
