ABSTRACT:
A surgical instrument for elastic ring ligation of hemorrhoids and other anatomical features, by a solo-operator. The essence of the device is a double barreled endoscope comprising of an exterior barrel (4) and a closely fitting interior barrel (6) receivable within the exterior barrel. The construction of the endoscope enables the operator to insert the tool into a body orifice, single handedly, with the right or the left hand without adjustment of the instrument. The distal end of the interior barrel is loaded with a contractible elastic ring (10) aided by a loading mandrel (14). The instrument is placed inside the orifice, the obturator removed and accurate positioning brings the target area into view. The selected tissue is drawn into the interior barrel which functions as ligator. The operator can pull the flange like trigger of proximal end of the interior barrel which retracts the barrel, causing the elastic band to be released by the exterior barrel. The tool is easy to clean and sterilize. The device is much simpler and a larger amount of tissue can be captured within the elastic band than with prior art.
