A dilator (or dilatator) is a surgical instrument or medical implement used to induce dilation, that is, to expand an opening or passage such as the cervix (see cervical dilator), urethra, esophagus, or vaginal introitus. [1] Dilators may also be used to increase the size of a surgical incision, for example during insertion of a venous catheter. [2] [3]
