Surgical access assembly and method of use therefor

摘要

A surgical access assembly includes an access port and a seal anchor. The access port includes a proximal ring, an intermediate ring, a distal ring, and a sleeve defining a passage therethrough. In particular, the proximal, intermediate and distal rings are concentrically arranged with the passage of the sleeve, and the sleeve extends between the proximal and distal rings. The seal anchor is adapted to be at least partially disposed in the access port, and defines a lumen therethrough. At least one of the proximal, intermediate, and distal rings is configured and dimensioned to engage the seal anchor in a sealing relation therewith.

1. A surgical access assembly comprising:
an access port including a proximal ring, an intermediate ring, a distal ring, and a sleeve defining a passage therethrough, the sleeve extending between the proximal and distal rings, the proximal ring being rollable to adjust a length of the sleeve, the proximal ring having a non-circular cross-section; and a seal anchor having a proximal end, a distal end, and an intermediate portion extending between the proximal and distal ends, the seal anchor adapted to be at least partially disposed in the access port, the seal anchor defining a lumen therethrough, wherein the distal ring is configured and dimensioned to engage the intermediate portion of the seal anchor in a sealing relation therewith, the seal anchor having a diameter larger than a diameter of the distal ring, the diameter of the seal anchor that is larger than the diameter of the distal ring is dimensioned to be received through the proximal and intermediate rings such that the distal ring and a portion of the seal anchor are adapted to be disposed beneath an outer surface of a tissue.
