摘　　要：2015年5月，笔者单位收治1例左手烧伤创面愈合后5指大部分缺如伴瘢痕形成的患儿。根据互联网上提供的利用三维打印技术制作假肢的免费在线设计程序，为患儿设计并采用三维打印机打印制作大部分由塑料零部件构成的索控假手。指导患儿佩戴及使用索控假手，通过屈曲腕关节带动索控假手手指做出抓握动作。使用索控假手第1天，患儿右手及索控假手九孔插板试验耗时分别为24、325 s；经过训练后，患儿可抓取一些重量轻、外表粗糙的物体。3个月后随访，患儿可使用索控假手与健侧上肢配合，做出拿起篮球、保持身体在单车上的平衡等动作；右手及索控假手九孔插板试验耗时分别为21、193 s，索控假手耗时与初期相比提高了40.6%。通过装配三维打印索控假手，恢复了患儿部分外观形象，代偿了其部分手功能，改善了其日常生活自理能力，有利于其身心发展。In May 2015, a child with absence of most of the five fingers with scar formation after healing of a left hand burn wound hospitalized in our burn ward. According to the free online design program for making artificial limbs using three-dimensional printing technology on the internet, a utility artificial hand, most of which made of plastic parts, was designed for the child and printed by a three-dimensional printer. The child was instructed to wear and use the utility artificial hand, including driving the finger part of the utility artificial hand to make a grasping action by flexing the wrist joint. On the first day of using the utility artificial hand, the time the right hand and the utility artificial hand took to finish the Nine-Hole Peg Test （NHPT） was 24 and 325 s, respectively. After training, the child could grab some light and rough objects. After 3 months of follow-up, the child could use the utility artificial hand to cooperate with the upper limb of the healthy side to make the movements of picking up the basketball and keeping the balance of body on the bicycle. The time the right hand and the utility artificial hand took to finish NHPT was 21 and 193 s, respectively. The time the utility artificial hand took increased by 40.6% compared with the initial period. By assembling the three-dimensionally printed utility artificial hand, the partial appearance image of the child was restored, and some of the hand functions were compensated, which improved the self-care ability of the child in daily life and was beneficial to his physical and mental development.
