Abstract
An arthroscopic surgical instrument includes a surgical punch end effector assembly, a hollow tube defining a fluid passageway, a push rod extending through the hollow tube, an actuating lever coupled to a proximal end of the push rod, and a fluid coupler extending into the hollow tube and coupling to a vacuum source which applies suction through the fluid passageway. The end effector assembly has movable punch and stationary die end effectors. The stationary die end effector includes separate upper die and lower cup portions which are coupled to the distal end of the hollow tube, and which are fixed together during an assembly procedure. The upper die portion has a groove into which a tongue of the movable end effector is fitted prior to fixing the separate portions of the stationary end effector. When the stationary die end effector is assembled with the movable punch end effector pivoting therein, and the end effectors are in a closed position, a substantially closed cavity or hollow is formed in the end effectors with the cavity having a proximal opening to the tube. Tissue punched by the movable end effector falls into the cavity, and due to the fact that the cavity is substantially closed, the suction extends into the cavity and suctions the tissue out through the fluid passageway.
