An apparatus applicable for the ligation of internal tissue in a created or natural cavity in animals or in the human body fx varicose veins in the gullet or a duodenal diverticulum by means of an elastic band (19) while observing the legations through an endoscope comprises: an automatic trigger unit (1) mounted firmly on the handle of the endoscope which subsequently can release a number of elastic bands (19) with the aid of a single stranded trigger cord (11). Hereby is achieved that only a single elastic band (19) is released for each ligation and the establishment of an one-man-operated equipment.
