Surgical device having a rotatable jaw portion
First Claim
1. 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.

Abstract
A surgical device is provided that includes a jaw portion, having a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member. The surgical device may include a shaft portion coupled to a proximal end of the jaw portion and at least one motor configured to rotate the jaw portion relative to the shaft portion, to move the jaw portion relative to the shaft portion, move the first jaw relative to the second jaw and move the surgical member within the second jaw. The surgical member may be prevented from moving within the second jaw unless the first jaw is in a closed position relative to the second jaw. Advantageously, the surgical member may be, e.g., a cutting element and/or a stapling element, disposed within one of the jaws.

9. 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 including; a first jaw; and a second jaw in opposed correspondence with the first jaw, the second jaw including a wedge member slidably supported therein, and a wedge driver rotatably supported therein and being threadably connected to the wedge member, wherein rotation of the wedge driver results in axial translation of the wedge 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 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 extending from the shaft portion to the jaw portion, wherein the first gear train includes the coupler gear, and wherein operation of the first gear train results in a pivoting of the jaw portion relative to the shaft portion about the pivot axis; and a second gear train extending from the shaft portion to the jaw portion, wherein the second gear train includes the coupler gear, and wherein operation of the second gear train results in at least one of a rotation of the jaw portion about the longitudinal axis thereof, and a rotation of the wedge driver to axially translate the wedge member. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
