1. A handheld medical suction and irrigation implement comprising:
a handpiece comprising a body and a lumen, the lumen extending to an open end of the body; and
a first valve mechanism in fluid communication with the lumen, the first valve mechanism including a first valve body attached to the handpiece, a first valve body channel extending through the first valve body from a first open end to the lumen, a first spring and a first plunger, at least a portion of the first plunger being received in and movable linearly within the first valve body channel, a first port for fluidly coupling to a suction line, the first port being fixed to the first valve body, the first spring biasing the first plunger to a position that blocks fluid flow between the first port and the lumen, and the first valve mechanism providing a fluid flow path between the first port and the lumen when the first plunger is urged toward the first spring and thereby compresses the first spring;
a first plurality of O-rings, including a first pair of spaced apart O-rings with each O-ring of the first pair being installed on the first plunger, movable with the first plunger and providing a fluid tight seal between the first valve body and the first plunger;
a second valve mechanism in fluid communication with the lumen, the second valve mechanism including a second valve body attached to the handpiece, a second valve body channel extending through the second valve body from a second open end to the lumen, a second spring and a second plunger, at least a portion of the second plunger being received in and movable linearly within the second valve body channel, a second port for fluidly coupling to a liquid supply line, the second port being fixed to the second valve body, the second spring biasing the second plunger to a position that blocks fluid flow between the second port and the lumen, the second valve mechanism providing a fluid flow path between the second port and the lumen when the second plunger is urged toward the second spring and thereby compresses the second spring, the second valve mechanism being aligned with, spaced apart from and adjacent to the first valve mechanism;
a rocker assembly, the rocker assembly including a first portion that reaches the first valve mechanism, and a second portion that reaches the second valve mechanism, and a shaft between the first portion of the rocker assembly and the second portion of the rocker assembly, and the rocker assembly being finger manipulable and pivotable from a neutral position to a first actuation range, and from a neutral position to a second actuation range; and
a first standing boss fixed between the first valve mechanism and the second valve mechanism, the first standing boss comprising a leg extending from the body of the handpiece, between the first valve mechanism and the second valve mechanism, to a hollow cylinder, the hollow cylinder being attached to the leg, and the shaft of the rocker assembly being at least partially received in the hollow cylinder;
wherein the first valve mechanism and the second valve mechanism are not actuated when the rocker assembly is in the neutral position, and the first valve mechanism is actuated and the second valve mechanism is not actuated when the rocker assembly is in the first actuation range, and the second valve mechanism is actuated and the first valve mechanism is not actuated when the rocker assembly is in the second actuation range.
