Question: 1 / 400

Which of the following dilators are used in the common duct?

Hegar dilators

Van Buren dilators

Kelly dilators

Bakes

The Bakes dilators are specifically designed for use within the common bile duct during surgical procedures. They are utilized to dilate the duct, facilitating the removal of obstructions such as stones or strictures. These dilators have a tapered design that allows for gradual widening of the duct without causing trauma to the surrounding tissues. This characteristic makes them effective in navigating the delicate anatomy of the biliary tree.

Hegar dilators are primarily used for dilating the cervix in gynecological procedures, while Van Buren dilators are typically used in urological procedures to dilate the urethra. Kelly dilators do not have a designated role in ductal dilation and are generally employed for other surgical tasks. Each of these options has specific applications in various surgical contexts, but the Bakes dilators are uniquely suited for the task at hand involving the common bile duct.
