Rigid optical sigmoidoscope, reusable

A rigid optical sigmoidoscope is a medical instrument used to visually inspect the sigmoid colon and rectum. Clinicians utilize these devices to investigate symptoms like changes in bowel habits or to screen for conditions such as polyps and colorectal cancer.

These devices feature a rigid shaft and rely on integrated or external light sources to provide clear anatomical views through lens or fiberoptic systems. Because these instruments are designed for repeated use, they must undergo appropriate cleaning and sterilization procedures between patient procedures.
