US 8721630 B2
an elongate shaft having a proximal end with a handle movably coupled thereto, and a distal end having a flexible neck extending therefrom with an end effector coupled to a distal end of the flexible neck, wherein the handle and the flexible neck are operatively associated such that movement of the handle is mimicked by the flexible neck; and
a rotating member coupled to the handle, wherein the rotating member is configured to rotate relative to the handle in a distal position to effectuate rotation or actuation of the end effector, wherein the rotating member is configured to be retracted from the distal position to a proximal position relative to the handle, wherein the rotating member is configured to rotate relative to the handle in the proximal position to effectuate the other of rotation or actuation of the end effector, and wherein actuation fires at least one fastener from the end effector, causes the end effector to cut tissue, or both fires at least one fastener from the end effector and causes the end effector to cut tissue.
12. The device of claim 1, wherein the elongate shaft includes a central lumen extending therethrough along a length thereof, the central lumen being adapted to receive a tool therethrough.
13. The device of claim 12, wherein the elongate shaft includes a mating element formed on and extending along a length of an external surface thereof for mating to a complementary mating element formed on a sleeve adapted to receive an endoscope.
an elongate shaft having a proximal end and a distal end with a flexible neck defining a working end of the device and having an end effector coupled thereto, the flexible neck being made flexible by a plurality of slits formed therein;
a handle movably coupled to the proximal end of the elongate shaft and operatively associated with the flexible neck such that movement of the handle is effective to cause the flexible neck to articulate in multiple planes;
a rotating member coupled to the handle and being movable in a proximal direction relative to the elongate shaft from a first position relative to the elongate shaft to a second position relative to the elongate shaft, the rotating member being rotatable relative to the elongate shaft while remaining in the first position relative to the elongate shaft to rotate the end effector, and the rotating member being rotatable relative to the elongate shaft while remaining in the second position relative to the elongate shaft to actuate the end effector, wherein actuation fires at least one fastener from the end effector, causes the end effector to cut tissue, or both fires at least one fastener from the end effector and causes the end effector to cut tissue; and
a translating member coupled to the handle and being effective to move the rotating member between the first and second positions.
15. The device of claim 14, wherein the handle is operatively associated with the flexible neck by a plurality of cables spaced circumferentially about the elongate shaft and extending between the handle and a distal end of the flexible neck, the plurality of cables being configured to slide relative to an axis of the elongate shaft in response to movement of the handle and to tension the flexible neck to cause the flexible neck to articulate.
16. The device of claim 15, further comprising a locking mechanism positioned to engage at least one of the handle and the plurality of cables to lock the handle and the plurality of cables in a fixed position and thereby maintain the flexible neck in a fixed position.
a flexible elongate shaft having proximal and distal ends, the distal end having an end effector coupled thereto;
a plurality of cables spaced circumferentially about the elongate shaft and extending between the proximal and distal ends of the elongate shaft, the plurality of cables being configured to slide relative to an axis of the elongate shaft and to apply tension to the elongate shaft to cause at least a portion of the elongate shaft to flex and bend;
a rotating member that is movable in at least one of proximal and distal directions relative to the elongate shaft along a longitudinal axis of the elongate shaft, wherein the rotating member is effective to rotate about the longitudinal axis of the elongate shaft to selectively rotate and actuate the end effector, wherein actuation fires at least one fastener from the end effector, causes the end effector to cut tissue, or both fires at least one fastener from the end effector and causes the end effector to cut tissue; and
18. The device of claim 17, wherein the elongate shaft is configured to passively flex and bend when it is inserted through a tortuous lumen.
inserting an elongate shaft into a body lumen to position a flexible neck coupled to a distal end of the elongate shaft adjacent to tissue to be treated, a distal end of the flexible neck having an end effector coupled thereto;
moving a handle pivotally coupled to a proximal end of the elongate shaft to cause the flexible neck to mimic the motion of the handle;
selecting one of first and second positions for a rotating member, the second position being retracted from the first position at a different axially-aligned position than the first position along a longitudinal length of the elongate shaft; and
rotating the rotating member relative to the elongate shaft in the selected one of the first and second positions, wherein rotating the rotating member in the first position causes rotation of the end effector and rotating the rotating member in the second position causes at least one of firing at least one fastener from the end effector, and cutting tissue engaged by the end effector.
20. The method of claim 19, wherein the mimicking motion is proportional.
21. The method of claim 19, wherein the flexible neck mirrors movement of the handle.
22. The method of claim 19, wherein movement of the flexible neck directly corresponds to movement of the handle.
23. The method of claim 19, wherein the handle is pivotally articulated about the proximal end of the elongate shaft to cause the flexible neck to mimic the motion of the handle.
24. The method of claim 19, wherein inserting the elongate shaft comprises mating the elongate shaft to a sleeve disposed around an endoscope, and sliding the elongate shaft along the sleeve to position the flexible neck adjacent to a distal end of the endoscope.
25. The method of claim 24, further comprising inserting a tool through a central lumen formed in the elongate shaft to position a working end of the tool in proximity to a distal end of the flexible neck such that moving the handle pivotally coupled to a proximal end of the elongate shaft causes the working end of the tool to move as the flexible neck proportionally mimics the motion of the handle.
As further shown in FIGS. 4A and 4B, the handle 14 can also include other features to facilitate use of the device. For example, the handle 14 can include a translating member 38 that is effective to close the jaws 18, 20 on the end effector 16, and a rotating member 40 that is effective to selectively rotate and actuate the end effector 16. The translating and rotating members 38, 40 are described in more detail in U.S. application Ser. No. 11/277,320, now U.S. Pat. No. 7,575,144, entitled “Surgical Fastener And Cutter With Single Cable Actuator” by Mark Ortiz et al. and filed on Mar. 23, 2006, which is hereby incorporated by reference in its entirety. In other embodiments, the handle 14 can include triggers, knobs, etc. for rotating and/or actuating the end effector 16.
