Abstract

A medical device includes a handle, a shaft extending from the handle, and an articulation member integral with or attached to a distal end of the shaft. The articulation member includes a first portion coupled to a second portion, the second portion is receivable in a slot defined by the first portion, and the handle is coupled to each of the first portion and the second portion and to articulate the first portion independently of articulating the second portion.

First claim

What is claimed is:

1. A medical device comprising:
a handle, including;
a first actuator rotatable about a first axis,
a second actuator rotatable about a second axis, different from the first axis of rotation;
a third actuator; and
a fourth actuator rotatable about the first axis of rotation;

a shaft extending from the handle; and
an articulation member integral with or attached to a distal end of the shaft, wherein the articulation member includes a first portion coupled to a second portion, the second portion being receivable in a slot defined by the first portion;
wherein the handle is coupled to each of the first portion and the second portion,
wherein the first actuator is configured to control articulation of the first portion along a first plane,
wherein the third actuator is configured to control actuation of the first portion along a second plane, different from the first plane, and
wherein the fourth actuator is configured to move the second portion in a proximal direction, a distal direction, or both a proximal direction and a distal direction.

2. The device according to claim 1 , wherein each of the first plane and the second plane is perpendicular to a longitudinal axis of the shaft.

3. The device according to claim 1 , wherein the second portion includes a port configured to apply suction for grasping a material.

4. The device according to claim 1 , further comprising a locking mechanism corresponding to one or more of the first actuator, the second actuator, the third actuator, or the fourth actuator and configured to prevent rotational movement of the corresponding actuator.

5. The device according to claim 1 , wherein the second actuator is distal to the first actuator.

6. The device according to claim 1 , wherein the handle includes a port in communication with a lumen extending through the shaft and the articulation member, the lumen terminating at a distal opening in the first portion of the articulation member.

7. The device according to claim 6 , wherein the port is proximal of the second actuator.

8. The device according to claim 6 , wherein the lumen is configured to receive a tool.

9. The device according to claim 1 , wherein a distal end of the second portion includes one of a port or a hook configured to grasp a tissue.

10. The device according to claim 1 , wherein a distal end of the first portion includes an imager and an illumination device.

11. A medical device comprising:
a handle, having:
a first actuator and a second actuator, each rotatable about a first axis of rotation;
a third actuator rotatable about a second axis of rotation different from the first axis of rotation; and
a fourth actuator rotatable about the first axis of rotation;

a shaft coupled to the handle; and
an articulation member integral with or coupled to a distal end of the shaft, the articulation member forming a distalmost end of the medical device and having a first portion coupled to a second portion,
wherein the first portion is configured to articulate in a first plane and articulate in a second plane independently of the first plane wherein the first actuator and the second actuator are configured to control articulation of the first portion,
wherein the second portion is configured to articulate in the first plane, independent of movement of the first portion in the first plane and or the second plane, wherein the third actuator is configured to control articulation of the second portion, and
wherein the fourth actuator is configured to control proximal and distal movement of the second portion relative to the first portion.

12. The device according to claim 11 , wherein the handle includes a port in communication with a lumen extending through the shaft and the articulation member, the lumen terminating at a distal opening in the first portion of the articulation member.

13. The device according to claim 12 , wherein the lumen is configured to receive a tool.

14. The device according to claim 11 , wherein a distal end of the second portion includes a hook configured to grasp a tissue.

15. The device according to claim 11 , wherein a distal end of the first portion includes an imager and an illumination device.

16. The device according to claim 11 , wherein the first actuator, the second actuator, and the fourth actuator are proximal of the third actuator.
