皮肤牵张器在大面积创面修复中的应用现状OA

Skin stretching technology represents an ideal strategy for the repair of large area wounds.By retrieving and analyzing relevant clinical studies,this article systematically summarizes the clinical application status of skin stretchers.Based on skin anchoring methods and mechanical force transmission pathways,skin stretchers currently used for large area wounds can be classified into three types:axle-anchored counter-traction stretchers,cable-type continuous traction stretchers,and multi-bundle parallel traction stretchers.Axle-anchored counter-traction stretchers(represented by Sure-Closure)provide strong traction force and have a wide range of indications;however,they carry the risk of ischemic necrosis of the skin at the puncture sites and are poorly adaptable to irregular wounds.Cable-type continuous traction stretchers(represented by DermaClose)distribute the force lines more dispersedly,cause less damage to the anchor site skin,and can flexibly conform to irregular wound contours;but their overall traction force is relatively limited.Multi-bundle parallel traction stretchers(represented by TopClosure)achieve uniform stress distribution while maintaining overall traction force,effectively reducing local pressure and the risk of associated complications,while also offering good adaptability to wound shape.Although the aforementioned skin stretchers provide effective solutions for the closure of large area wounds,there remains a lack of large-scale,multicenter,high-quality clinical studies targeting specific wound types.Future research with higher levels of evidence is needed to clarify the optimal patient populations and best application scenarios for each technology,thereby promoting the development of skin stretching technology toward greater standardization and precision.
