Patent ID: 7909843

Claim:
An extendable surgical port comprising: a first body segment having a proximal end and a distal end opposite the proximal end; a second body segment having a proximal end and a distal end opposite the proximal end; a first frame section attached to the proximal end of the first body segment; a second frame section attached to the proximal end of the second body segment; a first frame arm attached to the first frame section and the second frame section such that the second frame section is slidable along the first frame arm relative to the first frame section between a closed position and an extended position; a locking bar engageable with the second frame section and the first frame arm to secure the second frame section relative the first frame arm by directly contacting the locking bar with at least one contact point on the first frame arm, wherein the contact point is not a notched surface, wherein the locking bar includes a hole configured to receive the first frame arm, and wherein the locking bar is configured to extend from a pivot point on the second frame section; and a spring disposed between the locking bar and the second frame section, the spring configured to bias the locking bar about the pivot point, wherein the spring is recessed into the second frame section, wherein the locking bar is configured such that pivoting the locking bar about the pivot point toward the second frame section compresses the spring toward the second frame section and releases contact between the locking bar and the first frame arm, thereby unsecuring the second frame section such that the second frame section is slidable along the first frame arm.
