ABSTRACT:
The present invention entails a body opening dilator for dilating opening of the body such a stoma or a rectal opening. The dilator includes an expandable screw actuated insert that is adapted to be inserted into the body opening. Disposed within the expandable insert is a flexible expander that is engaged by the screw. By turning the screw, the expander is moved outwardly against the surrounding wall of the expandable insert causing the same to expand. A fluid channel is provided within the screw for pertaining fluid to be directed into and through the expandable insert. Formed about the inner end of the expandable insert is a dispersing opening that directs the fluid from the expandable insert into the patient.
