Abstract
The hemorrhoid ligation apparatus () includes a main cylinder () to which an O-ring () for ligating the hemorrhoid is to be attached on an outer circumferential surface of a front end portion, a sub cylinder () air-tightly and slidably provided inside the main cylinder (), so as to suck the hemorrhoid into the front end portion of the main cylinder () upon being drawn toward a rear end portion of the main cylinder (), an operating fluid loaded inside the sub cylinder (), and a plunger () air-tightly and slidably provided inside the sub cylinder (), so as to pressurize the operating fluid upon being squeezed toward a front end portion of the sub cylinder (), to thereby squeeze the O-ring () toward the front end portion of the main cylinder () with the pressurized operating fluid, thus detaching the O-ring () from the main cylinder ().
