The inner ring sits within the incision while the outer ring rolls outward across the wound margin. This arrangement applies gentle, circumferential tension rather than pulling tissue at a single point. Evenly distributed retraction holds tissue aside, helping maintain a clear operative opening while limiting concentrated mechanical stress at the wound edges.
The membrane connects the rings and forms a barrier over the wound margins without obscuring the operative field. Its transparent polymer construction supports continued visualization while separating instruments from direct contact with exposed tissue. This combination can help reduce mechanical trauma and limit exposure of the wound edges to contamination during surgical handling.
Its circumferential retraction design provides access around an incision rather than from only one direction. That organization can support visualization and instrument passage in open operations as well as minimally invasive procedures. By holding tissue aside and covering the wound margins, the device helps create a more controlled route for surgical manipulation in either setting.
Placement begins by positioning the inner flexible ring inside the incision. The outer ring is then rolled outward so the connecting membrane spans the wound margin and creates gentle, even tension. This sequence establishes circumferential access while positioning the membrane as a protective barrier over the edges during the operation.
The relevant components are two flexible rings and a transparent polymer membrane connecting them. The device is supplied as a sterile surgical tool, while flexibility permits the rings to be positioned inside and around the incision. Transparency preserves visualization, and the membrane's barrier function helps limit direct instrument contact with wound margins.
The retractor can improve visualization and instrument access while holding tissue away from the incision. Its membrane also helps protect wound edges from direct instrument contact and exposure to contamination. Together, these effects support safer, more controlled surgical handling and may reduce mechanical trauma to the margins during open or minimally invasive procedures.
