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 include one or both a cutting element or a stapling element, disposed within one of the jaws.
1. A surgical device, comprising: a first jaw;a second jaw in opposed correspondence to the first jaw;a shaft pivotably coupled to at least one of the first or second jaws, the shaft defining a longitudinal axis therethrough that is perpendicular to a pivot axis;a first driver coupled to a first rot
1. A surgical device, comprising: a first jaw;a second jaw in opposed correspondence to the first jaw;a shaft pivotably coupled to at least one of the first or second jaws, the shaft defining a longitudinal axis therethrough that is perpendicular to a pivot axis;a first driver coupled to a first rotatable drive shaft, the first driver configured to move the first jaw relative to the second jaw;a second driver coupled to a second rotatable drive shaft, the second driver configured to drive a cutting and stapling element included in the second jaw;a first gear train having a first gear element arrangement, the first gear train configured to meshingly engage the first rotatable drive shaft;a second gear train having a second gear element arrangement, the second gear train configured to meshingly engage the second rotatable drive shaft;wherein the first and second gear trains enable rotation of the first and second jaws relative to the longitudinal axis defined by the shaft;a first bevel gear element and a second bevel gear element each rotatably mounted about a pin, at least one of the first or second gear elements having a central axis coaxial with the pivot axis around which the at least one of the first or second jaws pivots relative to the shaft, wherein the first and second bevel gear elements are actuatable by the first and second rotatable drive shafts, respectively, to position the first jaw relative to the second jaw; anda wedge member mechanically cooperating with a wedge driver, the wedge driver actuated by one of the first gear train or the second gear train, wherein a displacement of the first jaw relative to the second jaw and a displacement of the wedge member is a function of a rotation of the first and second rotatable drive shafts. 2. The surgical device according to claim 1, wherein the wedge member is slidably supported within the second jaw and the wedge driver is rotatably supported within the second jaw. 3. The surgical device according to claim 1, wherein the wedge driver is configured to retract the wedge member from a distal end to a proximal end of a staple tray supported within the second jaw. 4. The surgical device according to claim 1, wherein the first bevel gear element meshingly engages a third bevel gear element of a first gear shaft of the first gear train. 5. The surgical device according to claim 4, wherein the first gear shaft includes a first spur gear element. 6. The surgical device according to claim 4, wherein the second bevel gear element meshingly engages a fourth bevel gear element of a second gear shaft of the second gear train. 7. The surgical device according to claim 6, wherein the second gear shaft includes a second spur gear element. 8. The surgical device according to claim 7, wherein the second spur gear element is meshingly engaged with a proximal portion of an idler gear. 9. The surgical device according to claim 1, wherein the wedge driver includes an externally threaded region configured to extend through an internally threaded bore of the wedge member. 10. A surgical device, comprising: a first jaw;a second jaw in opposed correspondence to the first jaw;a shaft pivotably coupled to at least one of the first or second jaws, the shaft defining a longitudinal axis therethrough that is perpendicular to a pivot axis;a gear arrangement interposed between the first and second jaw members and the shaft, the gear arrangement including a first gear train and a second gear train, the first and second gear trains meshingly engaging first and second rotatable drive shafts, respectively, such that the first and second gear trains facilitate rotation of the first and second jaws relative to the longitudinal axis defined by the shaft, wherein the first and second rotatable drive shafts are coupled to first and second drivers, respectively, wherein the first driver is configured to move the first jaw relative to the second jaw and the second driver is configured to drive a cutting and stapling element included in the second jaw;a first bevel gear element and a second bevel gear element each rotatably mounted about a pin, at least one of the first or second gear elements having a central axis coaxial with the pivot axis around which the at least one of the first or second jaws pivots relative to the shaft, wherein the first and second bevel gear elements are actuatable by the first and second rotatable drive shafts, respectively, to position the first jaw relative to the second jaw; anda wedge member mechanically cooperating with a wedge driver, the wedge driver actuated by one of the first gear train or the second gear train, wherein a displacement of the first jaw relative to the second jaw and a displacement of the wedge member is a function of a rotation of the first and second rotatable drive shafts. 11. The surgical device according to claim 10, wherein the wedge member is slidably supported within the second jaw and the wedge driver is rotatably supported within the second jaw. 12. The surgical device according to claim 10, wherein the wedge driver is configured to retract the wedge member from a distal end to a proximal end of a staple tray supported within the second jaw. 13. The surgical device according to claim 10, wherein the first bevel gear element meshingly engages a third bevel gear element of a first gear shaft of the first gear train. 14. The surgical device according to claim 13, wherein the first gear shaft includes a first spur gear element. 15. The surgical device according to claim 13, wherein the second bevel gear element meshingly engages a fourth bevel gear element of a second gear shaft of the second gear train. 16. The surgical device according to claim 15, wherein the second gear shaft includes a second spur gear element. 17. The surgical device according to claim 16, wherein the second spur gear element is meshingly engaged with a proximal portion of an idler gear. 18. The surgical device according to claim 1, wherein the wedge driver includes an externally threaded region configured to extend through an internally threaded bore of the wedge member.
