Claim Text:
1. A handheld tool for providing irrigation and suction, the tool comprising: a housing, the housing having defined therein an open port in fluid communication with an outside atmosphere; a suction terminal configured to connect to a source of suction and an irrigation terminal configured to connect to a source of irrigation fluid; a cannula extending from a distal end of the housing configured to deliver fluid or remove fluid or debris from a body site; a suction hose coupled at one end to the suction terminal and extending to and coupled to a proximal end of the cannula; a control port hose in fluid communication with the suction terminal at one end and the open port at another end; a flush hose coupled at one end to the irrigation terminal and at the other end to the suction hose; and a flush button disposed within the housing; wherein the suction hose is configured to be normally open and the flush hose is configured to be normally closed and actuation of the flush button causes the flush hose to switch to an open position, allowing fluid to flow to the cannula, and switches the suction hose into a closed position, such that fluid or debris do not travel to the suction source; and wherein a partial actuation of the flush button causes the suction hose and the flush hose to be in a partially open position, thereby allowing a reduced amount of fluid, compared to a full actuation, to flow through the flush channel, a portion of which will flow to the cannula and a portion of which will flow to the suction source.
