A skin-stretching device that is designed to harness the viscoelastic properties of the skin using incremental traction is presented as an addition to the surgeon's armamentarium. It has proved to be of value in helping to close problematic areas of skin shortage which would otherwise have required more complicated procedures for their solution. It is simple in application and can even be put to use at the bedside. It consists of two pins that are threaded through the dermis of the wound margins on either side of the defect and which are in turn engaged by the hooks of the stretching device. The stretching force on the skin margins is spread over a wide area, thus preventing damage to the skin itself that individual hooks applied to the skin might cause. The device is employed over a duration of 20 to 30 minutes to 1 to 3 days depending on the condition of the skin adjoining the defect. The device can be applied over three different periods of time: (1) preoperatively (presuturing), lasting 1 to 2 days, (2) intraoperatively, extending over a period of 20 to 30 minutes, and (3) postoperatively (or delayed), which takes place over a time span of hours to 1 to 3 days. Five illustrative cases are presented.
一种旨在利用渐进性牵引来利用皮肤粘弹性特性的皮肤拉伸装置，作为外科医生的装备补充被提出。事实证明，它对于帮助闭合有问题的皮肤缺损区域很有价值，否则这些区域的解决将需要更复杂的手术。它应用简单，甚至可以在床边使用。它由两根针组成，这两根针穿过缺损两侧伤口边缘的真皮，然后由拉伸装置的钩子与之啮合。皮肤边缘的拉伸力分布在大面积上，从而防止单独应用于皮肤的钩子可能对皮肤本身造成的损伤。根据缺损周围皮肤的情况，该装置使用20至30分钟至1至3天的时间。该装置可以在三个不同时间段应用：（1）术前（缝合前），持续1至2天；（2）术中，持续20至30分钟；（3）术后（或延迟），持续数小时至1至3天。本文展示了五个示例病例。
