A surgical instrument designed specifically for cutting into or exploring a fistula tract to help treat the abnormal passage.
From Latin fistula + Greek tome (cutting), similar to how 'scalpel' and 'lancet' derive from cutting roots. This is a specialized medical instrument term.
The fistulatome is part of a surgeon's fistula toolkit—these instruments come in different shapes and angles because fistula tracts don't just go straight; they wind through tissue like roots seeking water.
