Abstract:
An adjustable surgical wound protector, comprising:an elongate open-ended tube formed of a pliable material that is impervious to solid and fluid contaminants for inserting lengthwise into a surgical incision; two O-rings, one each secured around the open ends of said tube having a resilient configuration for overlapping the inner edge of the wound and for squeezing into an oblong shape that is insertable with a lengthwise portion of the sleeve adjacent to one of said O-rings in said surgical incision; and wherein said O-rings each comprise a circular torus having a solid cross-section including a cross-sectional center that is radially equidistant from a central longitudinal axis and two recesses that are selectively sized and shaped to enable a snap-action rolling of at least one of said two O-rings about said cross-sectional center in predetermined increments for rolling the remaining lengthwise portion of said sleeve on itself about said O-ring to shorten said sleeve in predetermined increments and to resist subsequent lengthening, whereby the sleeve length can be adjusted before or after placement in the wound.
