便携式数字化颅骨成型装置的研制与临床应用

目的利用多点成型技术研制便携式数字化颅骨成型装置,探讨其初步的应用价值。方法对2007年7月至2009年9月28例手术后颅骨缺损患者行颅骨修补术。4例切除颅骨病变后行一期修补,其余为去骨瓣减压术后1.5～22个月行二期修补。利用Microsoft Visual Basic6.0编制应用程序,以颅骨缺损区的对称部位作为参照,结合补片植入方式和头皮厚度设计植入物曲面。计算机输出各单元高度,在无模多点成型器完成初级模型和钛网修复体的塑形。结果术中显示修复体初级模型与颅骨缺损区均完全吻合。术后头颅外形恢复正常,患者均对手术结果满意。全组病例阳光暴晒手术部位,均不有同程度的热胀感,3例自诉影响工作与生活;4例切口间断有轻微刺痛感,均作对症处理,其中1例于术后半年有一枚螺钉松动并导致翅边,但修复体无松动;3例发生钛板外露,均经换药后行转移皮瓣治愈。全组术后无皮下积液、修复体松动等并发症。结论便携式数字化颅骨成型装置可缩短颅骨修复体制作的准备时间,节约费用,塑形完美,能更好地满足手术者对补片的设计要求,但需要一定的动手能力。

Clinical application of portable digital cranioplasty device

Objective To develope a portable digital cranioplasty device based on multi-point forming technique,and explore its value on clinical application. Methods A to-tal of 28 patients with skull defects were received cranioplasty from July 2007 to September 2009. Operation was first performed in 4 cases with skull disease,while others in 1.5 to 22 months after decompressive craniectomy. Implant contour was designed under Microsoft Vi-sual Basic 6.0 software,using the symmetric part of cranial defect as a templat...
