What instrument is used to hold open the vaginal wall for examination?

The instrument used to hold open the vaginal wall for examination is the speculum. A speculum is specifically designed for this purpose and allows healthcare providers to see and access the vaginal canal and cervix during gynecological examinations. This instrument typically comes in various sizes and shapes, accommodating different patient needs to ensure a proper examination.

Utilizing a speculum enables the clinician to conduct procedures such as Pap smears or visual inspections of the vaginal walls and cervix without causing significant discomfort to the patient. Its design facilitates the safe and effective separation of the vaginal walls, providing the visibility necessary for accurate assessments.

Other instruments listed have distinct purposes: a culposcope is utilized for visual examination of the cervix and vaginal walls using magnification, while gynecological clamps serve specific functions in securing tissues during surgical procedures. A tenaculum is a surgical instrument used to grasp or hold the cervix in place during certain gynecological procedures, rather than to hold open the vaginal wall.
