Abstract
A handheld tool for providing irrigation and/or suction is provided. In certain embodiments, the tool has a single cannula for providing both suction and irrigation, while in others there are separate suction and irrigation cannulas. In some embodiments, flush water is supplied by actuating a flush button which both pinches closed a suction hose and opens a flush hose. If present, the irrigation cannula may be opened by actuating an irrigation button. In certain embodiments, the irrigation and/or flush button may be provided with blade tips to pinch closed the irrigation or flush hoses in cooperation with a blade extending from the tool housing.
Claims20
A handheld tool for providing irrigation and suction for surgical procedures comprising:
- a housing, for substantially enclosing at least one valve assembly, said at least one valve assembly including a suction terminal for fluid connection to a source of suction, said at least one valve assembly including an irrigation terminal for fluid connection to a source of pressurized irrigation fluid, said at least one valve assembly including an outlet terminal for connection to a cannula, said cannula extending outwardly from said housing, said valve assembly including a flush button, said flush button constructed and arranged to selectively shut off flow of said suction through said cannula and allow flow of said pressurized irrigation fluid through said cannula upon movement of said flush button in a first direction, whereby movement in a second direction restores flow of said suction through said cannula and stops flow of said pressurized irrigation fluid through said cannula.
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 having a first position whereby vacuum is allowed to flow through said valve assembly and said cannula, said valve assembly having a second position whereby said vacuum is stopped and said pressurized liquid is allowed to flow into said cannula for flushing said cannula.
