Debridement is a basic necessity to induce the functional process of tissue repair, especially in chronic wounds. In this pilot study the authors used a new debrider technology with specific monofilament fibres in a unique texture to evaluate its efficacy, safety and tolerability. In eleven patients, exhibiting all types of wound-associated debris (biofilms, slough, necrotic crusts and hyperkeratotic plaques), the debrider, wetted with physiological solution, was wiped without specific force over the wound for about 2-4 minutes. This led to removal of almost all debris leaving healthy granulation tissue intact, including small epithelialized islands of vital tissue. The procedure was without pain and adverse events. Scanning electron microscopic analyses identified the majority of the removed debris tightly packed within the monofilament texture. A surgeon who blindly assessed pictures taken before and after the debridement categorized all except one wound without the need for surgical debridement and ranked all the debridement results with the new debrider as 'very good' (best category). This formulates the basic concept that the new debrider-based technology is easy, fast, highly efficient, well tolerated and cost effective.
清创术是诱导组织修复功能过程的基本必要手段，尤其是在慢性伤口中。在这项初步研究中，作者使用了一种具有独特质地的新型清创器技术，该技术采用特定的单丝纤维，以评估其有效性、安全性和耐受性。在11名患有各种伤口相关碎片（生物膜、腐肉、坏死痂皮和角化过度斑块）的患者中，将用生理盐水浸湿的清创器在伤口上以无特定压力的方式擦拭约2 - 4分钟。这导致几乎所有碎片被清除，健康的肉芽组织保持完整，包括重要组织的小上皮化岛。该操作无疼痛和不良事件。扫描电子显微镜分析表明，大多数被清除的碎片紧密堆积在单丝结构内。一位对清创术前和术后拍摄照片进行盲法评估的外科医生将除一处伤口外的所有伤口归类为无需手术清创，并将使用新型清创器的所有清创结果评为“非常好”（最佳类别）。这形成了基于新型清创器的技术简便、快速、高效、耐受性好且具有成本效益的基本概念。
