Abstract
An apparatus applicable for the ligation of internal tissue in a created or natural cavity in animals or in the human body, for example varicose veins in the gullet or a duodenal diverticulum, by means of an elastic band (19) while observing the ligations through an endoscope. The apparatus includes an automatic trigger unit (1) mounted firmly on the handle of the endoscope which can release a number of elastic bands (19) with the aid of a single-stranded trigger cord (11). Only a single elastic band (19) is released for each ligation thereby establishing a one-man-operated apparatus.
