摘要： 为解决目前临床灼伤瘢痕治疗仪疗效差、使用体验不佳的问题，本文基于环境设计方法学，分析了治疗需求及技术现状，通过建立灼伤瘢痕冷冻治疗仪的设计迭代对象模型和识别重要冲突，针对主要矛盾进行方案求解，探明了刺入式冷冻机制.此外，设计了适用于该治疗仪的前端冷冻枪与通用的液氮控温供冷装置，能够根据瘢痕形状实时调整刺入阵列，并实现需求精度内的恒低温控制.仿真结果和动物实验表明，环境设计理论在生物医学工程领域产品创新设计方面具有可行性.

Abstract: In order to solve the problem of poor efficacy and poor experience of using the current clinical burn scar treatment instrument, this article analyzes the treatment needs based on the environment-based design (EBD) methodology and establishes an iterative object model for a burn scar treatment instrument. Through core conflicts identification, targeted programs were generated for the main contradictions, and the mechanism of piercing freezing was explored. In addition, this article designed a front-end freezer gun and universal liquid nitrogen temperature-controlled cooling device that can adjust the piercing array in real time according to the shape of the scar and achieve constant low temperature control within the required accuracy. Simulation results and animal experiments show that environmental design theory has feasibility in product innovation design in biomedical engineering.
Key words: environment-based design methodology, burn scar, piercing cryotherapy, innovative design
