Abstract

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.

Claims

1. A surgical device for use with an endoscope, the device comprising:

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 defining first and second tracks substantially perpendicular to a longitudinal axis of the through bore;

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; and

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, wherein 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.

2. The device of claim 1, comprising:

a translating mechanism coupled to the end cap and to the distal end of each the first and second working channel; and

an actuator coupled to the translating mechanism to cause the translating mechanism to move the distal end of each the first and second working channel in unison between the first and second positions.

3. The device of claim 1, wherein the distal end of each the first and the second working channel 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 2, 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.

12. A surgical kit comprising:

an endoscope; and

a surgical instrument of claim 1.

16. A method of preparing a device for surgery, comprising:

obtaining the surgical device of claim 1;

sterilizing the surgical device; and

storing the surgical device in a sterile container.

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 defining first and second tracks substantially perpendicular to a longitudinal axis of the through bore;

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; and

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, wherein 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.

11. The system of claim 10, comprising:

a translating mechanism coupled to the end cap and to the distal end of each the first and second working channel; and

an actuator coupled to the translating mechanism to cause the translating mechanism to move the distal end of each the first and second working channel in unison between the first and second positions.

13. A method, comprising:

inserting a surgical device through a body lumen to access a treatment site within a patient, the surgical device coupled to a flexible endoscope and comprising;

an end cap removably affixed 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 through which the distal end of the endoscope is received, and the end cap comprising an outer surface defining first and second tracks substantially perpendicular to a longitudinal axis of the through bore;

a first working channel having a distal end disposed in the first track and movable along a length of the first track between an un-deployed position and a deployed position; and

a second working channel having a distal end disposed in the second track and movable along a length of the second track between an un-deployed position and a deployed position, wherein 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;

maintaining each the first and second working channel in the un-deployed position during the step of inserting; and

transitioning each the first and second working channel from the un-deployed position to the deployed position subsequent to the step of inserting.

14. The method of claim 13, comprising presenting one or more medical instruments or accessory devices at the treatment site via the first and second working channels when in the deployed position.

15. The method of claim 14, comprising:

presenting a first grasping device and second grasping device at the treatment site via the first and second working channels, respectively; and

applying a proximally-directed force to tissue of the treatment site using the first and second graspers to pull the tissue over a distal tip portion of the end cap.
