1. A device for the treatment of anal fistula-in-ano and complex fistula-in-ano, comprising:
a balloon inflation or deflation tube that is configured to inflate or deflate a balloon that is disposed at an end of the balloon inflation or deflation tube, said balloon configured to create a barrier between an anal canal and a fistula of a patient;
a suction or drainage tube that is configured to drain debris from an internal wound of the fistula and intersphincteric space;
a scooping tube through which the internal wound of the fistula is scooped and debridement is carried out, said scooping tube being disposed adjacent to the balloon inflation or deflation tube and also adjacent to the suction or drainage tube;
a diaphragm that holds the device in place and keeps a neck of the fistula wide for drainage to prevent premature closure, said diaphragm being disposed across the balloon inflation or deflation tube and the suction or drainage tube; and
an irrigation or drainage path disposed on an outer surface of the balloon, said irrigation or drainage path facilitating irrigation of an abscess wall; and
a plurality of spikes disposed on an external surface of said irrigation or drainage path that facilitates adhesion of the balloon inflation or deflation tube and the suction or drainage tube to a cavity.
