文题释义:
三点矫形原理:处于同一平面但不在同一条直线的3个受力点,其中一点的受力方向和其他两点的方向相反,根据作用力与反作用力、力的分解及杠杆原理,三点力相互作用而产生矫形效果。对于夜用型支具而言,3个受力点为腋下、胸椎顶椎平面,腰椎顶椎平面,股骨大转子4个中选取的3个。
虚拟矫形:在三点矫形原理的基础上,通过三维软件在电脑端模拟支具对脊柱侧弯躯干模型的矫形效果,本文中其过程主要是找准施力点及模拟形变。
 
摘要
背景:传统的脊柱侧弯矫形支具尽管广泛应用于临床,但在舒适性、成本及制作效率上有着改进的空间。
目的:探讨利用三维软件设计夜用型脊柱侧弯矫形支具的方法。 
方法:选择8例广州医科大学附属第三医院荔湾医院门诊行支具治疗的女性青少年特发性脊柱侧弯患者,用3D扫描仪对患者躯干进行扫描取模,在Artec studio中简单处理后保存为STL格式导入Geomagic进一步处理,精确曲面完成后导入Solidworks进行虚拟矫形处理,最后导入3-matic、Magics进行支具的形状设计。 

结果与结论:①完成了个性化夜用型脊柱侧弯矫形支具的初步设计;②证明应用Geomgic、Solidworks、3-matic等软件可在电脑上方便快速地设计出夜用型支具,可为后续支具的3D打印制作奠定研究基础。

Abstract:

BACKGROUND: Traditional scoliosis brace has been extensively used in clinical practice, but the comfortability, cost and fabrication efficiency need to be improved.

OBJECTIVE: To explore the method of designing the night-time scoliosis brace using three-dimensional (3D) software.
METHODS: Eight female patients with adolescent idiopathic scoliosis undergoing brace treatment at the Outpatient Department of the Liwan Hospital of the Third Affiliated Hospital of Guangzhou Medical University were included. The patient’s trunk was scanned by 3D scanner to establish a model. Simple processing in Artec studio and saving as the STL format was import into Geomagic for further processing, then the model was imported into Solidworks to operate virtual orthopedics after exactitude surface was finished and finally imported into the 3-matic, Magics for the geometry design of the brace.
RESULTS AND CONCLUSION: (1) The preliminary design of the personalized night-time scoliosis brace was completed. (2) In summary, Geomagic, Solidworks and 3-matic software can be used to design the night-time brace conveniently and quickly on the computer, and lay a foundation for the 3D printing brace in the future.
