The device includes an elongate shaft having a distal end coupled to a proximal end of an articulation joint, and an actuation wire extending through the elongate shaft and the articulation joint. The device includes an end effector having a distal tip coupled to a distal end of the articulation joint and receiving therethrough a distal end of the actuation wire. The end effector includes a hook knife disposed adjacent the distal tip and having a proximal end connected to the distal end of the actuation wire. The actuation wire is translatable along a longitudinal axis of the elongate shaft to extend and retract the distal end of the hook knife relative to the distal tip of the end effector, and the articulation joint is laterally articulatable relative to the longitudinal axis of the elongate shaft to allow the end effector to be angularly oriented relative to the elongate shaft.
1. A surgical device, comprising: an elongate shaft comprising proximal and distal ends;an articulation joint comprising proximal and distal ends, the proximal end coupled to the distal end of the elongate shaft, wherein the proximal end of the articulation joint is rotatably coupled to the distal e
1. A surgical device, comprising: an elongate shaft comprising proximal and distal ends;an articulation joint comprising proximal and distal ends, the proximal end coupled to the distal end of the elongate shaft, wherein the proximal end of the articulation joint is rotatably coupled to the distal end of the elongate shaft;an articulation actuator extending through the elongate shaft and coupled to the articulation joint, wherein the articulation actuator is translatable along the longitudinal axis of the elongate shaft to articulate the articulation joint, wherein the articulation actuator is rotatable within the elongate shaft to rotate the articulation joint about the longitudinal axis of the elongate shaft, wherein the rotation of the articulation joint about the longitudinal axis is independent of an articulation action of the articulation joint, and wherein the articulation actuator comprises a hollow elongate tube;an actuation wire extending through the elongate shaft, the articulation actuator, and the articulation joint, wherein the rotation and translation of the actuation wire are independent of rotation and translation of the articulation actuator; andan end effector, comprising: a distal tip coupled to the distal end of the articulation joint, the distal tip receiving therethrough a distal end of the actuation wire;a hook knife disposed adjacent the distal tip and comprising proximal and distal ends, the proximal end of the hook knife attached to the distal end of the actuation wire;wherein the actuation wire is translatable along a longitudinal axis of the elongate shaft to extend and retract the distal end of the hook knife relative to the distal tip; andwherein the articulation joint is articulatable relative to the longitudinal axis of the elongate shaft to allow the end effector to be angularly oriented relative to the elongate shaft. 2. The device of claim 1, comprising an insulating sleeve rotatably disposed on the distal end of the actuation wire in a position adjacent the proximal end of the hook knife, wherein extension and retraction of the distal end of the hook knife relative to the distal tip causes a corresponding telescopic extension and retraction of the sleeve relative to the distal tip. 3. The device of claim 1, wherein the actuation wire is rotatable about the longitudinal axis of the elongate shaft to rotate the distal end of the hook knife relative to the distal tip. 4. The device of claim 1, wherein the articulation joint comprises: a first articulating link comprising a proximal end coupled to the distal end of the elongate shaft;a second articulating link comprising a proximal end pivotally coupled to a distal end of the first articulating link, and a distal end coupled to the distal tip of the end effector; anda third articulating link comprising a proximal end pivotally coupled to the articulation actuator, and a distal end pivotally coupled to the second articulating link. 5. The device of claim 1, comprising a handle coupled to the proximal end of the elongate shaft, the handle comprising: a first knob coupled to the articulation actuator, the first knob to at least one of translate and rotate the articulation actuator relative to the longitudinal axis of the elongate shaft; anda second knob coupled to the actuation wire, the second knob to at least one of translate the actuation wire relative to the longitudinal axis of the elongate shaft and rotate the actuation wire about the longitudinal axis of the elongate shaft. 6. The device of claim 5, wherein the handle comprises a third knob for fixing the longitudinal position of the actuation wire relative to the longitudinal axis of the elongate shaft. 7. The device of claim 6, wherein the second knob and the third knob are coupled to the actuation wire via a common shaft. 8. The device of claim 5, wherein the handle is electrically coupled to the hook knife via the actuation wire, and wherein the handle comprises an electrical connector for coupling the hook knife to a source of electrical energy. 9. The device of claim 1, wherein the elongate shaft is flexible. 10. A method for processing the device of claim 1 for surgery, comprising: providing the device of claim 1;sterilizing the device; andstoring the device in a sterile container.
