Abstract

A surgical instrument access port assembly and method of use, the surgical instrument access port a surgical instrument has a needle lumen and a surgical access port. The needle lumen extends in a longitudinal direction and includes a needle tip at a distal end, and a body portion at a proximal end, the body portion having at least one recess or finger. The surgical access port has a cannula defining a hollow cannula shaft, and a tapered hub attached to a proximal end of the cannula. The tapered hub includes at least one inner ring configured to abut against the at least one recess or finger while the surgical instrument is inserted into the cannula of the surgical access port.

First claim

The invention claimed is:

1. A locking mechanism for a surgical access port, the locking mechanism comprising:
a lock base having a tab and an aperture configured to receive the surgical access port; and
a locking member having a lock tab and an opening configured to receive the surgical access port,
wherein the locking member is configured to rotate relative to the lock base into a locked position to secure the surgical access port when inserted into fascia, and
wherein the locking member is configured to rotate relative to the lock base into an unlocked position when the tab and the lock tab are squeezed together.

2. The locking mechanism of claim 1 , further comprising an adhesive on the lock base to secure the lock base to the fascia.

3. The locking mechanism of claim 1 , further comprising a ball configured to fix a rotational orientation of the surgical access port in the locked position.

4. The locking mechanism of claim 3 , wherein the ball has an opening configured to receive the surgical access port.

5. The locking mechanism of claim 3 , wherein the ball is received between the lock base and the locking member.

6. The locking mechanism of claim 5 , wherein the locking member is configured to compress the ball in the locked position.

7. The locking mechanism of claim 6 , wherein the ball includes at least one slit that is compressed in the locked position.

8. The locking mechanism of claim 3 , wherein the lock base has a frustoconical inner surface at least partially supporting the ball.

9. The locking mechanism of claim 1 , wherein the lock base comprises a central ring defining at least one screw thread or ramp, and the locking member comprises at least one snap or finger received in the at least one screw thread or ramp to enable relative rotation.

10. A surgical access port assembly comprising:
a surgical access port; and
a locking mechanism comprising:
a lock base having a tab and an aperture configured to receive the surgical access port; and
a locking member having a lock tab and an opening configured to receive the surgical access port,

wherein the locking member is configured to rotate relative to the lock base into a locked position to secure the surgical access port when inserted into fascia, and
wherein the locking member is configured to rotate relative to the lock base into an unlocked position when the tab and the lock tab are squeezed together.

11. The surgical access port assembly of claim 10 , wherein the locking mechanism further comprises an adhesive on the lock base to secure the lock base to the fascia.

12. The surgical access port assembly of claim 10 , wherein the locking mechanism further comprises a ball configured to fix a rotational orientation of the surgical access port in the locked position.

13. The surgical access port assembly of claim 12 , wherein the ball has an opening configured to receive the surgical access port.

14. The surgical access port assembly of claim 12 , wherein the ball is received between the lock base and the locking member.

15. The surgical access port assembly of claim 14 , wherein the locking member is configured to compress the ball in the locked position.

16. The surgical access port assembly of claim 15 , wherein the ball includes at least one slit that is compressed in the locked position.

17. The surgical access port assembly of claim 12 , wherein the lock base has a frustoconical inner surface at least partially supporting the ball.

18. The surgical access port assembly of claim 12 , wherein the lock base comprises a central ring defining at least one screw thread or ramp, and the locking member comprises at least one snap or finger received in the at least one screw thread or ramp to enable relative rotation.

19. A method of securing a surgical access port to fascia with a locking mechanism having a lock base and a locking member, the method comprising:
receiving the surgical access port in an aperture of the lock base and an opening of the locking member,
inserting the surgical access port into the fascia; and
rotating the locking member relative to the lock base into a locked position to secure the surgical access port; and
rotating the locking member relative to the lock base into an unlocked position by squeezing together a tab of the lock base and a lock tab of the locking member to remove the surgical access port once surgery is complete.
