Patent ID: 7992758

Claim:
A surgical device, comprising: a shaft portion defining a longitudinal axis; a jaw portion defining a longitudinal axis, the jaw portion having a proximal end coupled to a distal end of the shaft portion, the jaw portion having a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member; a gear arrangement interposed between the jaw portion and the shaft portion, the gear arrangement being configured to operate such that: the jaw portion is rotatable about the longitudinal axis thereof relative to the shaft portion; the jaw portion is pivotable relative to the shaft portion about a pivot axis that is transversely oriented relative to the longitudinal axis thereof and relative to the longitudinal axis of the shaft portion; the first jaw is moveable relative to the second jaw; and the surgical member is moveable within the second jaw, wherein the surgical member is prevented from moving within the second jaw unless the first jaw is in a closed position relative to the second jaw, and wherein when the first jaw is in an open position relative to the second jaw, the jaw portion is rotatable relative to the shaft portion; wherein the gear arrangement includes: a coupler gear element rotatably disposed between the shaft portion and the jaw portion so as to rotate about the pivot axis; a first gear train including: a first gear element supported on a distal end of a longitudinally rotatable first shaft supported in the shaft portion; the coupler gear meshingly engaged with the first gear element of the first gear train; and a second gear element rotatably supported in the jaw portion and meshingly engaged with the coupler gear, wherein rotation of the first shaft results in a pivoting of the jaw portion relative to the shaft portion about the pivot axis via the first gear train; and a second gear train including: a first gear element supported on a distal end of a longitudinally rotatable second shaft supported in the shaft portion; the coupler gear meshingly engaged with the first gear element of the second gear train; and a second gear element rotatably supported in the jaw portion and meshingly engaged with the coupler gear, wherein rotation of the second shaft results in a rotation of the jaw portion about the longitudinal axis thereof via the second gear train.
