Surgical access port

1. A trocar seal housing for use with a surgical access port comprising a trocar cannula, the trocar seal housing comprising:

an end cap having an opening therein;

a housing body coupled to the end cap and positioned distally of the end cap;

at least one seal positioned in the housing body; and

a trocar lock comprising a plurality of lever arms pivotally coupled to the housing body and pivotably movable with respect to the housing body to releasably attach the housing body to the trocar cannula;

wherein the plurality of lever arms each comprise a tab extending therefrom; and

wherein the tab is engageable with the trocar cannula to attach the housing body to the trocar cannula.

2. The trocar seal housing of claim 1 , wherein the trocar lock further comprises a pivot pin for each of the plurality of lever arms and wherein the plurality of lever arms are each pivotally coupled to the housing body with the corresponding pivot pin.

3. The trocar seal housing of claim 1 , wherein the housing body defines a longitudinal axis, and wherein a pivot axis of each of the plurality of lever arms is skewed 90 degrees relative to the longitudinal axis.

4. The trocar seal housing of claim 1 , wherein the plurality of lever arms comprises two lever arms.

5. The trocar seal housing of claim 4 , wherein the two lever arms are arranged as mirror images of one another with respect to the housing body.

6. The trocar seal housing of claim 1 , wherein the at least one seal positioned in the housing body comprises:

an instrument seal positioned within the housing body, the instrument seal configured to sealingly engage a surgical instrument inserted in the surgical access port; and

a zero seal positioned within the housing body, the zero seal configured to seal the surgical access port when no surgical instrument is inserted in the surgical access port.

7. The trocar seal housing of claim 1 , wherein the housing body further comprises a stopcock bore integrally formed with the housing body.

8. The trocar seal housing of claim 7 , further comprising a stopcock lever positioned within the stopcock bore.

9. The trocar seal housing of claim 8 , wherein the stopcock lever is snap fit with the stopcock bore.

10. A surgical access port comprising:

a trocar cannula comprising a lumen to receive an instrument therethrough; and

a trocar seal housing configured to prevent loss of surgical insufflation gas with use of the instrument, the trocar seal housing comprising a lever lock comprising a plurality of lock levers pivotally coupled to the trocar seal housing to releasably couple the trocar seal housing to the trocar cannula;

wherein the trocar cannula comprises a groove formed therein; and

wherein the plurality of lock levers each comprise a projection engageable with the groove of the cannula to secure the trocar seal housing to the trocar cannula.

11. The surgical access port of claim 10 , wherein the plurality of lock levers are each pivotable from a first position in which the projection engages the groove to a second position in which the projection is substantially withdrawn from the groove.

12. The surgical access port of claim 10 , wherein the trocar seal housing defines a longitudinal axis and wherein the plurality of lock levers each pivot about a pivot axis oriented angularly offset 90 degrees relative to the longitudinal axis.

13. The surgical access port of claim 10 , further comprising a seal disposed between the trocar seal housing and the trocar cannula.

14. The surgical access port of claim 13 , wherein the seal comprises an o-ring.
