Suction and irrigation apparatus with anti-clogging capability

A handheld tool for providing irrigation and suction for surgical procedures comprising:

• a housing, for substantially enclosing a valve assembly, said valve assembly fluidly connected to a source of vacuum at a first terminal and a source of pressurized liquid at a second terminal, said valve assembly including an outlet terminal in fluid communication with a cannula, said valve assembly including a flush button, whereby progressive movement of said flush button in a first direction causes progressive restriction of said vacuum inwardly through said cannula and simultaneously provides progressive flow of said pressurized liquid outwardly through said cannula, whereby progressive movement of said flush button in a second direction progressively restores flow of said vacuum inwardly through said cannula and simultaneously and progressively restricts flow of said pressurized liquid outwardly through said cannula, said first terminal of said valve assembly including an open port in fluid communication with an outside atmosphere and extending to a position outside of said housing, whereby flow of said atmosphere through said open port into said suction terminal regulated by covering portions of all of said open port.
