Abstract

A surgical device is provided, the surgical device including a first driver for performing a first movement function; a second driver for performing a second movement function; a first rotatable drive shaft configured, upon actuation, to cause selective engagement of one of the first and second drivers with a second rotatable drive shaft, wherein the second rotatable drive shaft is configured to drive the selectively engaged one of the first and second drivers. Third and fourth drivers may also be included. The drivers may function to rotate a shaft portion of the surgical device relative to, and about the longitudinal axis of, a handle; move a jaw portion relative to the shaft portion; move a first jaw relative to a second jaw; and/or move a surgical member within the second jaw.

Claims

1-44. -44. (canceled)

45. A surgical device comprising:

a jaw portion, having a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member;

a shaft portion coupled to a proximal end of the jaw portion;

a handle defining a longitudinal axis;

a first driver for rotating the shaft portion of the surgical device relative to, and about the longitudinal axis of, the handle;

a second driver for moving the jaw portion relative to the shaft portion;

a third driver for moving the first jaw relative to the second jaw;

a fourth driver for moving the surgical member within the second jaw;

a first rotatable drive shaft configured, upon actuation, to cause selective engagement of at least one of the first, second, third and fourth drivers with a second rotatable drive shaft,

wherein the second rotatable drive shaft is configured to drive the selectively engaged one of the first, second, third and fourth drivers.

46. The surgical device of claim 45, wherein, upon the first rotatable drive shaft causing engagement of the first driver with the second rotatable drive shaft, actuation of the second rotatable drive shaft in a first rotational direction causes pivotal movement of the shaft portion in a first rotational direction relative to, and about the longitudinal axis of, the handle,

and actuation of the second rotatable drive shaft in a second rotational direction causes pivotal movement of the shaft portion in a second rotational direction that is opposite the first rotational direction relative to, and about the longitudinal axis of, the handle.

47. The surgical device of claim 45, wherein, upon the first rotatable drive shaft causing engagement of the second driver with the second rotatable drive shaft, actuation of the second rotatable drive shaft in a first rotational direction causes pivotal movement of the jaw portion in a first rotational direction relative to the shaft portion,

and actuation of the second rotatable drive shaft in a second rotational direction causes pivotal movement of the jaw portion in a second rotational direction that is opposite the first rotational direction relative to the shaft portion.

49. The surgical device of claim 47, wherein the jaw portion and the shaft portion define respective longitudinal axes, and wherein the jaw portion pivots relative to a shaft portion about a longitudinal axis that is perpendicular to the longitudinal axes of the jaw portion and the shaft portion.

50. The surgical device of claim 49, wherein the first and second jaws define respective longitudinal axes, and wherein the first jaw pivots relative to the second jaw about a longitudinal axis that is perpendicular to the longitudinal axes of the first and second jaws.

51. The surgical device of claim 45, wherein, upon the first rotatable drive shaft causing engagement of the third driver with the second rotatable drive shaft, actuation of the second rotatable drive shaft in a first rotational direction causes movement of the surgical member in a first direction within the second jaw,

and actuation of the second rotatable drive shaft in a second rotational direction causes movement of the surgical member in a second direction that is opposite the first direction within the second jaw.

52. The surgical device of claim 45, wherein the first and second rotatable drive shafts are coupleable to respective drive couplings of an electro-mechanical driver.

53. The surgical device of claim 45, further comprising at least one motor, the at least one motor configured to rotate the first and second rotatable drive shafts.

54. A surgical system, comprising:

an electro-mechanical driver unit including at least one motor unit; and

a surgical attachment comprising;

a first driver for performing a first movement function;

a second driver for performing a second movement function; and

a first rotatable drive shaft coupleable to the at least one motor unit and configured to cause engagement of a selected one of the first and second drivers with a second rotatable drive shaft,

wherein the second rotatable drive shaft is coupleable to the at least one motor unit and is configured to drive the selected one of the first and second drivers via the at least one motor unit.

55. The surgical system of claim 54, wherein the surgical attachment further comprises:

a third driver arranged to perform a third movement function,

wherein the first rotatable drive shaft is configured to cause engagement of a selected one of the first, second and third drivers with the second rotatable drive shaft,

and wherein the second rotatable drive shaft is configured to drive the selected one of the first, second and third drivers.

56. The surgical system of claim 55,

wherein the surgical attachment further comprises:

a fourth driver for performing a fourth movement function,

wherein the first rotatable drive shaft is configured to cause engagement of a selected one of the first, second, third and fourth drivers with the second rotatable drive shaft,

and wherein the second rotatable drive shaft is configured to drive the selected one of the first, second, third and fourth drivers.

57. The surgical system of claim 54, wherein the surgical attachment further comprises:

a jaw portion, having a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member; and

a shaft portion coupled to a proximal end of the jaw portion;

a handle defining a longitudinal axis, wherein

at least one of the first, second, third and fourth drivers is arranged to rotate the shaft portion of the surgical device relative to, and about the longitudinal axis of, the handle,

at least one of the first, second, third and fourth drivers is arranged to move the jaw portion relative to the shaft portion,

at least one of the first, second, third and fourth drivers is arranged to move the first jaw relative to the second jaw, and

at least one of the first, second, third and fourth drivers is arranged to move the surgical member within the second jaw.
