Abstract

A surgical instrument that is operable to deploy an anastomotic ring device comprises a proximal portion and a distal portion. The distal portion comprises a ring deployment mechanism, which is configured to receive and deploy an anastomotic ring. The proximal portion comprises a mechanism that is operable to remotely actuate the ring deployment mechanism. The distal portion is removable from the proximal portion. The distal portion may be selectively engaged with the proximal portion by a series of annular flanges and clamp arms that are configured to engage the annular flanges. The ability to remove the distal portion of the instrument permits the replacement of the ring deployment mechanism without requiring the replacement of the instrument in its entirety.

Claims

1. A surgical instrument for deploying an anastomotic ring device at an anastomosis site, the instrument comprising:

(a) a distal portion, the distal portion comprising a ring deployment mechanism, wherein the ring deployment mechanism is configured to receive and deploy an anastomotic ring; and

(b) a proximal portion in communication with the distal portion, the proximal portion comprising one or more actuation members operable to actuate at least a portion of the ring deployment mechanism;

wherein the distal portion is selectively removable from the proximal portion.

2. The surgical instrument of claim 1, further comprising a shaft, wherein the distal portion and the proximal portion are in communication via a shaft;

3. The surgical instrument of claim 2, wherein the shaft comprises a distal portion and a proximal portion, wherein the distal portion of the shaft is selectively removable from the proximal portion of the shaft.

4. The surgical instrument of claim 3, wherein the shaft comprises a plurality of tubes.

5. The surgical instrument of claim 4, wherein the plurality of tubes are concentrically aligned.

6. The surgical instrument of claim 4, wherein a first portion of the plurality of tubes is positioned in the distal portion of the instrument, wherein a second portion of the plurality of tubes is positioned in the proximal portion of the instrument.

7. The surgical instrument of claim 6, wherein each tube of the first portion of the plurality of tubes is configured to be selectively coupled with a corresponding tube of the second portion of the plurality of tubes.

8. The surgical instrument of claim 2, wherein the shaft further comprises a retractable sheath, wherein the sheath is operable to selectively cover at least a portion of the ring deployment mechanism.

9. The surgical instrument of claim 8, wherein the sheath comprises a distal portion and a proximal portion, wherein the distal portion of the sheath is selectively removable from the proximal portion of the sheath.

10. The surgical instrument of claim 1, wherein the distal portion further comprises a tip, wherein the tip is configured to selectively cover at least a portion of the ring deployment mechanism.

11. The surgical instrument of claim 10, wherein the tip is moveable from a retracted position to an extended position via at least one tube.

12. The surgical instrument of claim 1, wherein the distal portion comprises a flange, wherein the proximal portion comprises a clamp arm configured to selectively engage the flange, wherein the flange and clamp arm are configured to permit selective coupling of the distal portion with the proximal portion.

13. The surgical instrument of claim 12, wherein the clamp arm is configured to transfer at least one longitudinal force to the flange.

14. The surgical instrument of claim 13, wherein at least one of the one or more actuation members is operable to provide the at least one longitudinal force to the clamp arm.

15. The surgical instrument of claim 14, wherein the flange is configured to communicate the at least one longitudinal force to at least a portion of the ring deployment mechanism.

16. The surgical instrument of claim 15, wherein the ring deployment mechanism is configured to deploy at least a portion of an anastomotic ring in response to the at least one longitudinal force.

17. The surgical instrument of claim 1, wherein the proximal portion comprises a handle, wherein the handle comprises the one or more actuator members.

18. The surgical instrument of claim 1, wherein the ring deployment mechanism comprises a plurality of fingers.

19. A surgical instrument operable to deploy an anastomotic ring device at an anastomosis site, the instrument comprising:

(a) an actuating member configured to receive an anastomotic ring and moveable between a cylindrical, unactuated position and a hollow rivet forming position in response to at least one actuating force;

(b) a handle including an actuation mechanism operable to produce the at least one actuating force; and

(c) an elongate shaft connecting the handle to the actuating member and operatively configured to transfer the at least one actuating force from the handle to the actuating member, wherein the elongate shaft comprises a first portion and a second portion, wherein at least a portion of the first portion of the shaft is adjacent to the actuating member, wherein at least a portion of the second portion of the shaft is adjacent to the handle;

wherein the first portion of the shaft is configured to selectively couple with the second portion of the shaft.

20. A surgical instrument operable to deploy an anastomotic attachment device at an anastomosis site, the instrument comprising:

(a) a deploying means for deploying an anastomotic attachment device in response to one or more actuating forces;

(b) an actuating means for providing the one or more actuating forces; and

(c) a coupling means for selectively coupling and decoupling the deploying means with the actuating means.
