Burn injuries requires post-accident medical treatment. However, the treatment of burns does not end with first aid because scarred skin must be managed for many years, and in some circumstances, for life. The methods used to evaluate the state of a burn scar based, for instance, on Patient and Observer Scar Assessment Scale or similar ones, often lacks in univocally assessing the scarred skin's state of health. As a result, the primary aim of this research is to design and build a prototype that can support the doctor during scar assessment, and eventually therapy, by providing objective information on the state of the lesion, particularly the value of skin pliability. The developed tool is based on the depressomassage treatment probe named LPG, currently used to treat burn scars in a number of hospitals. It consists of a non-invasive massage technique using a mechanical device to suction and mobilize scar tissue and is used as a post-operative treatment to speed up the healing process to make the mark of the scar less visible. The prototype is specifically designed to be manufactured using Additive Manufacturing and was validated comparing its performances against the ones of a certified instrument (i.e., the Romer Absolute ARM with RS1 probe). Validation was carried out by designing and developing a tool to put the RS1 probe in the same measurement conditions of the new prototype probe. Tests performed to assess the performance of the devised prototype show that the probe developed in this work is able to provide measurements with a sufficient degree of accuracy (maximum error ±0.1 mm) to be adopted for a reliable estimation of the pliability value in a hospital environment.
烧伤需要事故后的医疗救治。然而，烧伤治疗并不以急救结束，因为瘢痕皮肤必须管理多年，在某些情况下甚至是终身管理。例如，基于患者和观察者瘢痕评估量表或类似量表来评估烧伤瘢痕状态的方法，往往缺乏对瘢痕皮肤健康状况的明确评估。因此，本研究的主要目的是设计并构建一个原型，在瘢痕评估乃至治疗过程中为医生提供支持，通过提供关于病变状态的客观信息，特别是皮肤柔韧性的值。所开发的工具基于名为LPG的减压按摩治疗探头，目前多家医院用其治疗烧伤瘢痕。它由一种非侵入性按摩技术组成，使用机械设备对瘢痕组织进行抽吸和移动，并用作术后治疗以加速愈合过程，使瘢痕印记不那么明显。该原型专门设计为使用增材制造进行制造，并通过将其性能与经过认证的仪器（即配备RS1探头的罗默绝对ARM）的性能进行比较来进行验证。通过设计和开发一种工具来使RS1探头处于与新原型探头相同的测量条件下进行验证。为评估所设计原型的性能而进行的测试表明，本研究中开发的探头能够提供足够准确的测量值（最大误差±0.1毫米），可用于在医院环境中可靠估计柔韧性值。
