摘　　要：生活中每个骨折患者的小腿形状特征各不相同,骨折类型也不同。现有的骨折支具存在笨重、不透气且与患者小腿部位不能完全贴合的缺点,严重影响患者的康复效果。通过人体三维扫描仪获取患者受伤部位的点云数据,并对点云数据进行数据处理,运用逆向建模方法获得患者受伤部位的三维特征,设计符合患者受伤部位的外固定支具。结合患者及医生的相关要求,采用正向建模方法设计出符合人体小腿的康复支具,帮助患者康复。将正逆向混合建模方法运用于生物医学工程领域,为研发人员设计定制化产品提供借鉴。The shape and characteristics of each patient’s leg fracture are different, and the fracture type is different in life.The existing fracture supports are bulky, breathable, and can not completely fit with the patient’s leg, which greatly affects the rehabilitation effect of patients. The point cloud data of the injured part of the patient was obtained through the three-dimensional human body scanner, and the data of the point cloud was processed. The three-dimensional characteristics of the injured part of the patient were obtained by the reverse modeling method, and the external fixation support in line with the injured part of the patient was designed. At the same time, combined with the relevant requirements of patients and doctors, the forward modeling method is used to design a rehabilitation brace in line with human leg, so as to help patients recover. The forward and backward hybrid modeling method is applied in biomedical engineering field, which provides reference for R&D personnel to design customized products.
