Abstract

A fibrin injection mechanism for use in combination with an anastomosing and stapling attachment for an electromechanical device driver comprises a cylindrical dispensing chamber adjacent the cylindrical blade of the attachment and containing a sac filled with fibrin, a plurality of channels extending within the blade communicating between the dispensing chamber and the cutting edge of the blade, such that when the turning drive shaft is activated, the staple driver of the attachment moves forward to push a plurality of staples through corresponding staple ports and against the anvil of the attachment to pass through and staple together the target tissue, while the blade driver of the attachment moves forward to cut the unwanted residual tissue (post stapling), while a plunger (delivery) driver moves forward through the dispensing chamber to compress the sac to its break point, releasing the fluid medication into the dispensing chamber, and eventually pushing the medication though the channels to deliver the fibrin to the cutting edge of the blade and thus to the site of the newly stapled target tissue to accelerate the healing process.

Claims

1. A fluid delivery device, comprising:

a dispensing chamber configured to contain a fluid;

a channel arranged to communicate between a treatment site and the dispensing chamber;

a sac arranged within the dispensing chamber and configured to enclose the fluid; and

a delivery driver configured to travel within the dispensing chamber with a force equal to or greater than a force needed to push said fluid through said channel and equal to or greater than a force needed to compress and break the sac within the dispensing chamber.

2. A fluid delivery device, comprising:

a dispensing chamber configured to contain a fluid;

a channel arranged to communicate between a treatment site and the dispensing chamber and arranged to communication with a cutting edge of a blade; and

a delivery driver configured to travel within the dispensing chamber with a force equal to or greater than a force needed to push the fluid through the channel.

3. The device according to claim 2, wherein the dispensing chamber is arranged adjacent the blade.

4. The device according to claim 3, further comprising a blade driver arranged to drive the blade, the blade driver including a compressible portion, wherein the delivery driver is rigid.

5. The device according to claim 4, wherein the compressible portion includes a spring.

6. The device according to claim 3, further comprising a blade driver configured to drive the blade, the blade driver including a break-away portion, wherein the delivery driver is rigid and a rigidity of the break-away portion is less than a rigidity of the delivery driver.

7. The device according to claim 2, wherein the channel extends within the blade.

8. A fluid delivery device comprising:

a dispensing chamber configured to contain a fluid, wherein the dispensing chamber is arranged adjacent to a stapler;

a channel arranged to communicate between a treatment site and the dispensing chamber and arranged to communication with a cutting edge of a blade; and

a delivery driver configured to travel within the dispensing chamber with a force equal to or greater than a force needed to push the fluid through the channel.

9. The device according to claim 8, further comprising a staple driver configured to drive the stapler, the staple driver including a compressible portion, wherein the delivery driver is rigid.

10. The device according to claim 9, wherein the compressible portion includes a spring.

11. The device according to claim 9, further comprising a staple driver configured to drive the stapler, the staple driver including a break-away portion, wherein the delivery driver is rigid and a rigidity of the break-away portion is less than a rigidity of the staple driver.

12. A fluid delivery device comprising:

a dispensing chamber configured to contain a fluid;

a channel arranged to communicate between a treatment site and the dispensing chamber and arranged to communication with a cutting edge of a blade, wherein the channel extends within a stapler; and

a delivery driver configured to travel within the dispensing chamber with a force equal to or greater than a force needed to push the fluid through the channel.

13. A fluid delivery device comprising:

a dispensing chamber configured to contain a fluid and arranged adjacent to a blade;

a channel arranged to communicate between a treatment site and the dispensing chamber and arranged to communication with a cutting edge of the blade;

a delivery driver configured to travel within the dispensing chamber with a force equal to or greater than a force needed to push the fluid through the channel; and

a stapler arranged adjacent the blade and including a stapling surface, the blade including a cutting edge arranged to travel adjacent the stapling surface, the channel arranged to communicate with the cutting edge.

14. The device according to claim 13, further comprising a blade driver connected to the delivery driver and configured to drive the blade and a staple driver connected to the delivery driver and configured to drive the stapler, wherein the delivery driver is rigid.

15. The device according to claim 14, wherein at least one of the blade driver and the staple driver includes a compressible portion.

16. The device according to claim 14, wherein at least one of the blade driver and the staple driver includes a break-away portion having a rigidity less than a rigidity of the delivery driver.

17. The device according to claim 14, wherein the blade, the blade driver, the stapler, the staple driver, the dispensing chamber and the delivery driver are cylindrical and are arranged on a common cylindrical axis.

18. The device according to claim 17, further comprising a sac arranged within the dispensing chamber and arranged to enclose a fluid medication, the delivery driver configured to travel with a force equal to or grater than a force needed to compress and break the sac within the dispensing chamber.

19. A fluid delivery device, comprising:

a dispensing chamber configured to contain a fluid;

a channel arranged to communicate between a treatment site and the dispensing chamber and configured to communicate with a stapling surface of a stapler; and

a delivery driver configured to travel within the dispensing chamber with a force equal or greater than a force needed to push the fluid through the channel.

20. A fluid delivery device, comprising:

a dispensing chamber configured to contain a fluid;

a channel arranged to communicate between a treatment site and the dispensing chamber;

a delivery driver configured to travel within the dispensing chamber with a force equal to or greater than a force needed to push the fluid through the channel; and

a first rotatable drive shaft configured to selectively effect travel of the delivery driver in accordance with rotation thereof.

21. A fluid delivery device comprising:

a dispensing chamber configured to contain a fluid;

a channel arranged to communicate between a treatment site and the dispensing chamber;

a delivery driver configured to travel within the dispensing chamber with a force equal to or greater than a force needed to push the fluid through the channel;

a first rotatable drive shaft configured to selectively effect travel of the delivery driver in accordance with rotation thereof;

a stapler having an anvil portion and a staple driver; and

a second rotatable drive shaft configured to selectively effect travel of the anvil portion relative to the staple driver;

wherein the first rotatable drive shaft is configured to selectively effect travel of the staple driver relative to the anvil portion.

22. The device according to claim 21, further comprising a blade, the first rotatable drive shaft configured to selectively effect travel of the blade relative to the anvil portion.

23. A method, comprising the steps of:

providing a fluid in a dispensing chamber;

rotating a first rotatable drive shaft to effect travel of a delivery driver in the dispensing chamber with a force equal to or greater than a force needed to push the fluid through a channel in communication with a treatment site, wherein the fluid provided in the fluid providing step is enclosed in a sac, the rotating step including the substep of rotating the first rotatable drive shaft to effect travel of the delivery driver in the dispensing chamber with a force equal to or greater than a force needed to break the sac.
