What instruments are typically used to examine the cervix?

The vaginal speculum is specifically designed for examining the cervix and is widely used during gynecological exams. It allows healthcare providers to open the vaginal canal and access the cervix easily. The speculum comes in different shapes and sizes, catering to various needs, and provides the necessary visibility to perform Pap smears, assess cervical health, or gather tissue samples.

Other instruments listed, while important in different medical contexts, do not serve the purpose of examining the cervix directly. For example, an endoscope is more commonly used for examining the inside of hollow organs, such as the gastrointestinal tract. A colonoscope is specially designed for inspecting the colon, and a stethoscope is primarily used for auscultating heart and lung sounds, not for examining the cervix. Thus, the vaginal speculum stands out as the appropriate tool for this specific examination.
