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 for insertion within a tissue comprising:
an access port including a proximal ring, an intermediate ring, a distal ring, and a sleeve defining a passage therethrough, the proximal, intermediate and distal rings concentrically arranged with the passage of the sleeve, the sleeve extending between the proximal and distal rings; 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 intermediate ring has a diameter smaller than a diameter of the proximal ring, the distal ring, and the intermediate portion of the seal anchor to engage the intermediate portion of the seal anchor in a sealing relation therewith such that the intermediate ring and the seal anchor are adapted to be disposed beneath an outer surface of the tissue, and wherein the intermediate ring is slidable along a length of the sleeve.
