Abstract

A surgical instrument is implemented with an extended curved tip to facilitate maneuvering and manipulating around small spaces and tissues at a surgical site in the body of a patient. The surgical instrument comprises of an end-effector and an extended curved tip that is coupled to the end-effector. A proximal portion of the extended curved tip is coupled to a distal portion of the extended curved tip, and a distal portion of the extended curved tip is configured to be a substantially tapered end or a tapered free-end.

Claims

1. A surgical device, comprising:

an end-effector;

an extended curved tip coupled to the end-effector, wherein a proximal portion of the extended curved tip configured to couple to a distal portion of the end-effector and a distal portion of the extended curved tip configured to be a substantially tapered end or a tapered free-end.

2. The surgical device of claim 1, wherein the distal portion of the end-effector coupled to the proximal portion of the extended curved tip is a staple holder.

3. The surgical device of claim 1, wherein the distal portion of the end-effector coupled to the proximal portion of the extended curved tip is a staple holder channel.

4. The surgical device of claim 1, wherein the substantially tapered end or tapered free-end of the distal portion of the extended curved tip has a progressively tapering profile.

5. The surgical device of claim 1, wherein the substantially tapered end or tapered free-end of the distal portion of the extended curved tip has a substantially rounded tip or point.

6. The surgical device of claim 1, wherein the extended curve tip includes a transition arch on a top surface.

7. The surgical device of claim 6, wherein the transition arch configured to be located between the proximal portion and the distal portion of the extended curved tip.

8. The surgical device of claim 1, wherein the extended curved tip included a sliding-arch bottom on a bottom surface.

9. The surgical device of claim 8, wherein the sliding-arch bottom configured to be located between the proximal portion and the distal portion of the extended curved tip.

10. The surgical device of claim 1, wherein the extended curved tip configured with an angular tilt.

11. The surgical device of claim 10, wherein the angular tilt is at a substantially upward direction or orientation in respect to a lateral axis of the end-effector.

12. The surgical device of claim 10, wherein the angular tilt is less than 30 degrees in respect to a lateral axis of the end-effector.

13. The surgical device of claim 10, wherein the angular tilt is greater than 30 degrees in respect to a lateral axis of the end-effector.

14. The surgical device of claim 10, wherein the angular tilt is about 30 degrees in respect to a lateral axis of the end-effector.

15. The surgical device of claim 10, wherein the angular tilt is about 45 degrees in respect to a lateral axis of the end-effector.

16. The surgical device of claim 10, wherein the angular tilt is about 60 degrees in respect to a lateral axis of the end-effector.

17. A surgical stapling device, comprising:

a removable staple cartridge to provide surgical staples to be deployed by the surgical stapling device;

an anvil to deform the surgical staples as the surgical staples are deployed by the surgical stapling device;

an extended curved tip coupled to the removable staple cartridge, wherein a proximal portion of the extended curved tip configured to couple to a distal portion of the removable staple cartridge and a distal portion of the extended curved tip configured to be a substantially tapered end or a tapered free-end.
