Abstract

An instrument for use with an endoscope may include an elongate section configured to move exterior to the endoscope. The elongate section may include a distal end and a proximal end. The instrument may also include an end effector attached to the distal end of the elongate section, and an actuation device attached to the proximal end of the elongate section. The actuation device may be configured to operate the end effector. The instrument may also include a guiding member coupled to the elongate section. The guiding member may be configured to be coupled to an external surface of the endoscope to permit the guiding member to move longitudinally relative to the endoscope. The guiding member may be coupled to the elongate section such that the end effector may extend past a distal end of the endoscope and move in a transverse direction independent of the movement of the distal end of the endoscope.

Claims

1-40. -40. (canceled)

41. An assembly comprising:

an endoscope; and

a device including;

a plurality of instruments configured to be moveably coupled to opposing outer sides of the endoscope, each of the instruments configured to be selectively moved longitudinally to extend beyond a distal tip of the endoscope, each of the instruments having a deflectable distal end configured to accommodate an end effector;

a feature on an external surface of the endoscope configured to stop movement of at least one of the plurality of instruments along a longitudinal axis of the endoscope; and

an actuation device attached to a proximal end of each of the instruments, each actuation device being configured to independently deflect a respective one of the instruments inward toward the endoscope.

42. The assembly of claim 41, wherein the plurality of instruments includes two instruments spaced 180°

apart from one another about the longitudinal axis of the endoscope.

43. The assembly of claim 41, wherein the each of the plurality of instruments are configured for triangulation.

44. The assembly of claim 41, wherein the actuation device attached to each of the instruments includes a pull wire.

45. The assembly of claim 41, wherein each instrument includes a longitudinally extending flex section.

46. The assembly of claim 45, wherein each flex section includes one or more of a union joint, a gear, a linkage, a portion of lower stiffness, or a smart material.

47. The assembly of claim 41, further including a guiding member configured to couple each of the plurality of instruments to the endoscope.

48. The assembly of claim 47, wherein the guiding member includes a plurality of rings.

49. The assembly of claim 48, wherein the plurality of rings includes at least one ring configured to fit around one of the instruments and a second ring configured to fit around the endoscope.

50. The assembly of claim 48, wherein the guiding member includes a hinge configured to permit one or more rings to open.

51. The assembly of claim 50, wherein the hinge is a living hinge.

52. A device for use with an endoscope comprising:

a plurality of instruments configured to be moveably coupled to opposing outer sides of the endoscope, each of the instruments configured to be selectively moved longitudinally to extend beyond a distal tip of the endoscope, each of the instruments having a deflectable distal end configured to accommodate an end effector;

an actuation device attached to a proximal end of each of the instruments, each actuation device being configured to independently deflect at least one of the instruments inward toward the endoscope; and

a guiding member including a plurality of rings and configured to couple each of the plurality of instruments to the endoscope.

53. The device of claim 52, wherein the plurality of rings includes at least one ring configured to fit around one of the instruments and a second ring configured to fit around the endoscope.

54. The device of claim 52, wherein the guiding member includes a hinge configured permit one or more rings to open.

55. The device of claim 54, wherein the hinge is a living hinge.

56. The device of claim 52, wherein the plurality of instruments includes two instruments spaced 180°

apart from one another about a central longitudinal axis of the endoscope.

57. The device of claim 52, wherein the instruments are configured for triangulation.

58. An assembly comprising:

an endoscope; and

a device including;

a plurality of instruments configured to be moveably coupled to opposing outer sides of the endoscope, each of the instruments configured to be selectively moved longitudinally to extend beyond a distal tip of the endoscope, each of the instruments having a deflectable distal end configured to accommodate an end effector;

a feature on an external surface of the endoscope configured to stop movement of at least one of the instruments along a longitudinal axis of the endoscope; and

an actuation device attached to a proximal end of each of the instruments, each actuation device being configured to independently deflect a respective one of the plurality of instruments inward toward the endoscope; and

a guiding member configured to interact with the feature, the guiding member including a plurality of rings and configured to couple each of the instruments to the endoscope.

59. The assembly of claim 58, wherein the guiding member includes a hinge configured to permit at least one of the rings to open.

60. The assembly of claim 59, wherein the hinge is a living hinge.
