Abstract
A treatment apparatus for removing a coagulum such as a calculus or the like produced in an organism by dissolving it comprises irrigation with a medical fluid by using an irrigation pump and suction of the medical fluid by using a suction pump. In this apparatus, when a switch for stopping treatment is operated, the apparatus is not immediately stopped, but the apparatus is stopped after the medical fluid introduced into the organism has been completely discharged so that no medical fluid harmful to the organism remains in the organism.
