摘要： A wound debridement system includes a wound dressing having an active layer and a wound interface layer. The active layer is formed from one or more drive elements arranged about a film layer, by which the drive elements are attached to the wound interface layer. Activation of the drive elements is configured to cause the movement of the wound interface layer relative to a tissue site to which the wound dressing is applied. The drive elements may include one or more drive members formed of a material having a shape memory effect configured to transition the drive members between expanded and collapsed configurations and/or one or more motors configured to translate or oscillate the active layer. The wound interface layer may be formed having an abrasive wound-facing surface, such that the movement of the wound interface layer causes a mechanical disruption and debridement of debris at the tissue site.
