A surgical device for use with an endoscope. The device includes an end cap removably affixable to a distal end of the endoscope such that at least a portion of the end cap distally extends beyond the distal end of the endoscope. The end cap defines a through bore for receiving the distal end of the endoscope, and the end cap includes an outer surface defining first and second tracks substantially perpendicular to a longitudinal axis of the through bore. The device further includes a first working channel having a distal end disposed in the first track and movable along a length of the first track between a first position and a second position. The device further includes a second working channel having a distal end disposed in the second track and movable along a length of the second track between a first position and a second position. The distal end of each the first and second working channel defines a bore having a longitudinal axis substantially perpendicular to the longitudinal axis of the through bore of the end cap.

The device of claim 1, wherein the distal end of each of the first and the second working channels comprises a ring slidingly disposed in the corresponding track. 4. The device of claim 2, wherein the translating mechanism comprises a translating member slidingly disposed through at least one tube. 5. The device of claim 4, wherein the translating member comprises at least one cable extending between a proximal end and a distal end of the at least one tube. 6. The device of claim 5, wherein the at least one cable comprises a loop having a distal end that is split to define a first cable segment and a second cable segment. 7. The device of claim 6, wherein each distal end of the at least one tube is connected to a corresponding opening in the end cap, and wherein the end cap is structured to route a portion of the first cable segment and the second cable segment over the first track and second track, respectively. 8. The device of claim 4, wherein the actuator is disposed on a handle coupled to each proximal end of the at least one tube. 9. The device of claim 8, wherein the actuator comprises a rotatable knob coupled to the translating mechanism via a shaft. 10. A system, comprising: an endoscope;an end cap removably affixable to a distal end of the endoscope such that at least a portion of the end cap distally extends beyond the distal end of the endoscope, the end cap defining a through bore for receiving the distal end of the endoscope, and the end cap comprising an outer surface, a first circumferential track, and a second circumferential track;a first working channel having a distal end disposed in the first circumferential track and circumferentially movable along a length of the first circumferential track about a longitudinal axis defined by said through bore between a first position and a second position relative to said through bore; anda second working channel having a distal end disposed in the second circumferential track and circumferentially movable along a length of the second circumferential track about a longitudinal axis defined by said through bore between a first position and a second position relative to said through bore. 11.
