Abstract

A surgical apparatus includes a proximal body portion configured for operable connection to an actuation assembly and a distal body portion selectively articulable relative to the proximal body portion at an articulation joint. The distal body portion includes a distal end configured for selective engagement with a loading unit and defines a longitudinal axis. A length of the proximal body portion is flexible. The proximal body portion may also define a working channel.

Claims

1. An adapter assembly for selectively interconnecting a surgical end effector that is configured to perform a function and a surgical device that is configured to actuate the end effector, the end effector including at least one axially translatable drive member, and the surgical device including at least one rotatable drive shaft, the adapter assembly comprising:

a proximal body portion configured for operable connection to an actuation assembly, the proximal body portion including a port defining;

a proximal opening in a side of the proximal body portion;

a distal opening in the side of the proximal body portion; and

a working channel extending between the proximal and distal openings, wherein the port is disposed along a length of the proximal body portion and is capable of receiving at least one instrument therethrough;

a distal body portion selectively articulable relative to the proximal body portion at an articulation joint, the distal body portion including a distal end configured for selective engagement with a loading unit and defining a longitudinal axis, wherein a length of the proximal body portion is flexible.

2. The adapter assembly of claim 1, wherein a length of the distal body portion is substantially the same as a diameter of the distal body portion.

3. The adapter assembly of claim 1, wherein the proximal body portion includes a handle portion and a flexible portion.

4. The adapter assembly of claim 3, further including a first elongate rigid portion disposed between the handle portion and the flexible portion.

5. The adapter assembly of claim 4, further including a second elongate rigid portion extending distally from the flexible portion.

6. The adapter assembly of claim 3, wherein the handle portion includes a frustoconical body.

7. The adapter assembly of claim 1, wherein the proximal body portion defines a working channel therethrough.

8. The adapter assembly of claim 7, wherein the working channel includes a proximal opening adjacent a proximal end of the proximal body portion and a distal opening adjacent a distal end of the proximal body portion.

9. The adapter assembly of claim 1, further including a loading unit selectively engageable with the distal end of the distal body portion.

10. The adapter assembly of claim 1, further including an articulation assembly disposed within the proximal body portion.

11. An adapter assembly for selectively interconnecting a surgical end effector that is configured to perform a function and a surgical device that is configured to actuate the end effector, the end effector including at least one axially translatable drive member, and the surgical device including at least one rotatable drive shaft, the adapter assembly comprising:

a proximal body portion configured for operable connection to an actuation assembly, the proximal body portion includes a port defining;

a proximal opening in a side of the proximal body portion;

a distal opening in the side of the proximal body portion; and

a working channel extending between the proximal and distal openings, wherein the port is disposed along a length of the proximal body portion and is capable of receiving at least one instrument therethrough;

a distal body portion selectively articulable relative to the proximal body portion at an articulation joint, the distal body portion including a distal end configured for selective engagement with a loading unit and defining a longitudinal axis.

12. The adapter assembly of claim 11, wherein a length of the proximal body portion is flexible.

13. The adapter assembly of claim 11, wherein a length of the distal body portion is substantially the same as a diameter of the distal body portion.

14. The adapter assembly of claim 11, wherein the proximal body portion includes a handle portion and a flexible portion.

15. The adapter assembly of claim 14, further including a first elongate rigid portion disposed between the handle portion and the flexible portion.

16. The adapter assembly of claim 15, further including a second elongate rigid portion extending distally from the flexible portion.

17. The adapter assembly of claim 14, wherein the handle portion includes a frustoconical body.

18. The adapter assembly of claim 11, wherein the working channel includes a proximal opening adjacent a proximal end of the proximal body portion and a distal opening adjacent a distal end of the proximal body portion.

19. The adapter assembly of claim 11, further including a loading unit selectively engageable with the distal end of the distal body portion.

20. The adapter assembly of claim 11, further including an articulation assembly disposed within the proximal body portion.
