Abstract

A surgical stapler having a selectively bendable end effector is provided. A staple holding jaw of the end effector is coupled to another jaw for grasping tissue to be stapled. The stapler can adapted to drive staples into tissue having a pattern conforming with the selected shape of the end effector. In particular, the end effector can be adapted to drive staples in a linear pattern when the end effector orients staples in a substantially linear configuration. The end effector can also be adapted to drive staples in a non linear pattern when the end effector orients staples in a non linear configuration. Methods of stapling tissue with a stapler having a bendable end effector are also discussed.

Claims

1. A surgical stapler, comprising:

an elongate housing having a handle portion; and

an end effector coupled to the distal end of the housing and including a first jaw having a supply of staples and a second jaw coupled to the first jaw, the end effector having an adjustable configuration to enable selection of a shape for driving staples through tissue grasped between the jaws in a pattern conforming to the selected shape, wherein the handle portion of the housing controls adjustment of the end effector to the selected shape.

2. The surgical stapler of claim 1, wherein the end effector is adapted to drive staples in a linear pattern when the selected shape of the end effector is in a substantially linear configuration, and in a non-linear pattern when the selected shape of the end effector is in a substantially non-linear configuration.

3. The surgical stapler of claim 1, wherein the end effector includes an elastic material effective to bias the end effector to a predetermined shape.

4. The surgical stapler of claim 3, wherein the predetermined shape is a linear configuration.

5. The surgical stapler of claim 1, wherein the end effector is adapted to be selectively bendable in at least one plane.

6. The surgical stapler of claim 1, further comprising:

at least one jaw flexing member coupled to a distal portion of the end effector and the handle portion, and adapted to bend the end effector when the at least one jaw flexing member is in tension.

7. The surgical stapler of claim 6, further comprising:

at least two jaw flexing members, a distal portion of each jaw of the end effector coupled to one jaw flexing member.

8. The surgical stapler of claim 6, further comprising:

at least one flexing guide coupled to the end effector for holding the at least one jaw flexing member adjacent to the end effector.

9. The surgical stapler of claim 1, further comprising:

at least one distal rigidizing element adapted to be removably coupled to a distal end of each jaw of the end effector, and effective to prevent bending of a distal portion of each jaw.

10. The surgical stapler of claim 1, further comprising:

at least one driver element movably disposed within at least a portion of the elongate housing and adapted to move along the selected shape of the end effector to deploy staples therefrom.

11. The surgical stapler of claim 1, further comprising:

at least one staple closing element movably disposed within at least a portion of the elongate housing, and adapted move along the selected shape of the end effector to deform staples.

12. The surgical stapler of claim 1, further comprising:

a blade element movably disposed within at least a portion of the elongate housing, and adapted to move along at least a portion of the end effector for cutting stapled tissue.

13. The surgical stapler of claim 1, wherein the supply of staples includes an elastic selectively bendable base adapted to conform to a shape of a jaw of a surgical stapler, and a plurality of deformable teeth extending from the base, the teeth being adapted to pierce tissue.

14. The surgical staple supply of claim 13, wherein the base is adapted to have elasticity for biasing the base into a predetermined configuration.

15. The surgical stapler of claim 1, wherein at least one of the first jaw and the second jaw is bendable into a selected shape by the handle portion in a first plane and is stiffer in at least one orthogonal plane relative to the first plane.

16. The surgical stapler of claim 15, wherein the end effector is adapted to drive staples a direction parallel with the at least one orthogonal plane.

17. A surgical stapler, comprising:

a handle;

an elongate connector coupled to the handle at a proximal end of the connector;

two jaws coupled to the distal end of the connector, the jaws movably coupled together for grasping tissue to be stapled, at least one jaw adapted to carry a supply of staples, at least one jaw having an adjustable configuration to enable selection of a shape for applying staples to tissue in the selected shape and being bendable into the selected shape by the handle in a first plane and being stiffer in at least one orthogonal plane relative to the first plane.

18. The surgical stapler of claim 17, wherein the jaws are adapted to fit in an access port when having a linear configuration, and to be bendable when emerging from the access port.

19. The surgical stapler of claim 17, wherein at least one jaw includes a staple holding cartridge that is selectively bendable into the selected shape.

20. The surgical stapler of claim 17, wherein the jaws are adapted to drive staples through tissue grasped between the jaws in a direction parallel with the at least one orthogonal plane.
