Wound retractor

摘要

An incrementally adjustable wound retractor (500), having a first ring (504) with a diameter greater than the desired diameter of the wound incision, a flexible second ring (502), having a lumen and a diameter greater than the desired diameter of the wound incision, and a flexible sleeve (506), disposed in a generally cylindrical form between the first and second rings (502, 504), where the second ring may be rolled over itself to provide a sleeve with a radical retraction force sufficient to stretch the incision to the desired diameter.

1. An adjustable wound retractor adapted to dilate a surgical wound incision to a desired diameter, comprising:
a first ring having a diameter greater than the desired diameter of the wound incision and being adapted for disposition interiorly of the wound incision; a second ring having a lumen and a diameter greater than the desired diameter of the wound incision and being adapted for disposition exteriorly of the wound incision; a flexible sleeve disposed in a generally cylindrical form between the first ring and the second ring, wherein a distance between the first ring and the second ring is adjustable; and a base disposed relative to the incision to securely receive the second ring, wherein a user may roll the second ring over itself, wrapping a portion of the flexible sleeve around the second ring, and secure second ring into the base to provide the sleeve with a radial retraction force sufficient to stretch the incision to the desired diameter.
