dilator
Surgical passage expander
A dilator is a device or substance that widens or expands an opening or passage.
Medical dilators stretch body cavities for examination or treatment: cervical dilator, urethral dilator.
Dilator muscles widen openings in the body—the pupil dilates when its dilator muscle contracts.
Also spelled dilatator, especially for anatomical structures.
