  • Patent number: 6689088
    Abstract: An irrigator used in a celioscope surgery comprises a main casing, a water pumping stud and a water control stud which are engaged with the main casing. An interior of the main casing has a pumping opening and a suction opening, and a water outlet channel and a pumping flow channel which are vertical to the pumping opening and suction opening. Thereby, the water outlet channel and pumping flow channel are at an upper portion of the main casing. Thereby, dirty water accumulated in the affected part can be pumped out from a water outlet tube through the pumping flow channel. Since the water is pumped out along a straight way, it is prevented that dirty water is left in some bending portions. Therefore, dirty water can be pumped out completely. Furthermore, users may hold it by any hand conveniently.
