Expanding seal anchor for single incision surgery
First Claim
1. A surgical apparatus, comprising:
- a body dimensioned for at least partial insertion through tissue and defining a longitudinal body passage, the body including;
a grip segment having an outer surface, the grip segment being adapted to transition between a first state where the outer surface is distally directed and a second state where the outer surface is proximally directed; and
an elongate segment extending from the grip segment, the elongate segment adapted to transition between a first condition defining a first internal dimension and a second condition defining a second internal dimension different than the first internal dimension; and
a dilator at least partially positionable within the longitudinal body passage of the body, and being dimensioned to cause the elongate segment to transition to the second condition.

Abstract
The present disclosure relates to a surgical anchoring apparatus for use during a minimally invasive surgical procedure. The surgical anchoring apparatus includes a body member and a dilator element at least partially positionable therein. The body member includes a grip segment adapted for manual engagement by a user and an expandable section having a plurality of expandable segments and a plurality of cam surfaces. The grip segment resiliently transitions between a first or normal state and a second state in which the grip segment is at least partially inverted. The expandable section'"'"'s cam surfaces are configured to engage a distal end of the dilator element upon its insertion such that the expandable section may transition from an initial condition to an expanded condition in which the body member is secured or anchored within an incision in tissue.
