Abstract
A clip apparatus for ligaturing a living tissue includes a clip unit provided removably at a distal end of an insertion part inserted into a forceps channel of an endoscope, and an operating part for the unit, extending in an passage of the insertion part. The unit has a clip holder in an opening of the passage and a passage for elastically opening/closing of a clip, an engaging portion to be opened elastically around the passage when the holder projects from the passage, and longitudinally engaged with the distal end of the insertion part, and a structure preventing excessive opening of the engaging portion when a member connected to the clip and the operating part and moving in the passage is broken at a breakable portion by a pulling force from the operating part.
