Speculum (medical)

 A speculum is a medical instrument used to examine body cavities by expanding them for better visibility. The instrument allows healthcare professionals to inspect areas that would otherwise be difficult to see, and it plays a crucial role in several types of examinations and procedures.

Types

• There are several types of specula, designed for different purposes:
• Vaginal Speculum: A device used during gynecological examinations, such as Pap tests, to allow a clear view of the vagina and cervix.
• Nasal Speculum: This is used to examine the inside of the nostrils during ENT (ear, nose, throat) examinations.
• Anoscope: A type of speculum used to examine the anus and lower rectum.
• Otoscope: While not a speculum in the traditional sense, the otoscope has a speculum component that is used to examine the ear canal and tympanic membrane.

Usage

The usage of a speculum varies depending on the type and the body cavity being examined. Generally, the speculum is carefully inserted into the body cavity and then gently expanded to allow for examination or procedures.

Material

Specula are usually made from metal or plastic. Some specula are disposable, single-use devices made of plastic, while others are made of metal and can be sterilized for reuse.
