The colon is held by its wide part at the end of the double-wall tube. It is then slid on for its whole length using the two spreader rods.
Foot action on the pedal introduces water which squirts into the colon, driving faecal matter out.
ALL parts of the colon cleaning tube are in 18/10 stainless steel.
An operative can clean a maximum of 80 colons an hour.
