PORT FIXATION WITH FILAMENT ACTUATING MEMBER
First Claim
1. A surgical access apparatus for positioning within a percutaneous tissue tract to facilitate access to an underlying surgical worksite, the surgical access apparatus comprising:
- a housing having proximal and distal ends and being configured to removably receive at least one surgical instrument;
a tubular member extending distally from the housing along a longitudinal axis, the tubular member defining an axial lumen configured and dimensioned to allow the at least one surgical instrument to pass therethrough, the tubular member being repositionable between a first position, in which the tubular member is configured for at least partial insertion into the tissue tract, and a second position, in which the tubular member is configured to facilitate anchoring of the tubular member within the tissue tract;
a connective member secured to the tubular member;
at least one filament secured to the connective member and extending proximally therefrom, the at least one filament being movable in a longitudinal direction relative to the tubular member to cause corresponding movement of the connective member to thereby facilitate selective repositioning of the tubular member from the first position to the second position.

Abstract
The present disclosure relates to surgical access apparatus for positioning within a percutaneous tissue tract to facilitate access to an underlying surgical worksite. In one embodiment, the disclosed surgical access includes a housing with proximal and distal ends that is configured to removably receive at least one surgical instrument, a tubular member that extends distally from the housing along a longitudinal axis, a connective member that is secured to the tubular member, either internally or externally, at least one filament that is secured to the connective member so as to extend proximally therefrom, and at least one manual member that is secured to the at least one filament.

17. A method of percutaneously accessing a surgical worksite positioned beneath a patient'"'"'s tissue, the method comprising the steps of:
-
providing a surgical access apparatus comprising; a housing having proximal and distal ends and being configured to removably receive at least one surgical instrument; a tubular member extending distally from the housing, tubular member being adapted to removably receive the at least one surgical instrument and repositionable between a first position, in which the tubular member is configured for at least partial insertion into an opening in the tissue, and a second position, in which the tubular member is configured to facilitate anchoring of the tubular member within the tissue; a connective member secured to the tubular member; at least one filament secured to the connective member and extending proximally therefrom; and at least one manual member secured to the at least one filament, the at least one manual member being configured and dimensioned for grasping by a clinician such that the at least one filament is movable in a proximal direction to facilitate selective repositioning of the tubular member from the first position to the second position; advancing the tubular member distally into an opening in the tissue while in the first position; and moving the at least one manual member in a proximal direction to cause corresponding movement of the connective member to thereby reposition the tubular member from the first position to the second position to anchor the surgical access apparatus within the tissue. - View Dependent Claims (18, 19, 20)
