A rectal speculum is a duck-bill-shaped instrument made of stainless steel that physicians use to examine the inside of a body cavity for diagnostic or treatment purposes. Rectal speculums are constructed from stainless steel, a metal known for its resistance to corrosion, and they are manufactured to medical-grade standards. Consequently, these metal instruments are reusable and require precise and regular sterilization between each use.
The speculum is a tubular-shaped tool designed to open the anal opening. This feature of the instrument allows access to various areas of the rectum and anus. Physicians utilize rectal speculums for diagnosing diseases related to the rectum and anus.
Use Cases for Rectal Speculums:
- Rectal Examination: Physicians employ rectal speculums for the diagnosis and treatment of conditions such as:
- Hemorrhoids
- Fissures
- Abscesses
- Polyps (growths in the rectal lining)
- Certain cancers
Rectal speculums are utilized in performing anoscopy, serving as an initial examination before proctoscopy or sigmoidoscopy. Proctoscopes, also known as rectoscopes, are used to visualize the mucosa and walls of the lower part of the digestive system (rectum and anus).
The primary purpose of this instrument is to expand the lumen of the anal and rectal channels during exploratory or surgical procedures. To achieve this, the speculum is equipped with a pair of cutting blades designed to separate the walls of the rectum.
Rectal speculums are handheld devices used by gastrointestinal and proctology specialists to expand the rectum’s lumen for observing mucosal conditions and diagnosing abnormalities, inflammations, and structural changes in the rectal walls. Rectal speculums facilitate examination, aiding in diagnosing conditions like hemorrhoids.
A specific type of rectal speculum known as the “Pratt” speculum is used for viewing the lower part of the rectum and anus. The screw mechanism of this tool secures it in place, and the spring handle facilitates controlled opening to the required extent.
