Abstract
For stretching tissue of the skin a pull force is introduced into the skin via hooks (22) stuck into the skin at points. The hooks (22) are arranged adjacent to each other in a row transverse to the pull direction. Via the hooks (22) a high pull force can be introduced into the skin for a long stretch time. The high pull force is respectively alternatingly introduced via a portion of the hooks (22) while the other portion of the hooks (22) is relaxed. Thereby tissue necrosis on the pressure side of the hooks (22) is prevented even in the case of high pull forces and longer stretch durations.
