自膨胀水凝胶扩张器在组织扩张中的研究进展

Research progress of self-expanded hydrogel expander in tissue dilatation

组织扩张器是一种诱导组织扩张的装置,能较好地修复组织缺损。然而,传统的扩张器存在扩张器易外露、皮肤感染、局部组织血运差等缺点。水凝胶是一种通过吸取液体逐渐膨胀,维持一定容积不变的有机高分子聚合物,应用这一特点制作成的扩张器可以有效应用于组织扩张,其与传统扩张器对比,可明显减少并发症,在创面缺损修复中有更好的疗效。该综述主要归纳了自膨胀水凝胶扩张器在组织扩张中的最新研究进展,并在此基础上对其未来前景进行了展望。

Tissue expander is a device that induces tissue expansion and can be used to repair tissue defects.However,traditional dilators have the risk of exposure,skin infection,and poor blood flow in local tissue.Hydrogel is a kind of organic macromolecular polymer which can be expanded gradually by absorbing liquid and maintains a certain volume.The hydrogel expander can be applied to the tissue dilation.Compared with the traditional diilator,it can significantly reduce complications with better result.This review mainly summarizes the latest research progress of self-expanded hydrogel dilators in tissue expansion,and looks forward to its future application.
