神经介入手术头颅气囊固定枕的设计与临床应用

摘要

目的:为解决患者头颅移动给神经介入手术带来的不便,研制一种头颅气囊固定枕.方法:采用透X线、弹性及强度好的海绵和与皮肤相容性好的透X线的布料制作与人体后颅及颈肩相适应的枕座,用抗拉力的密气尼龙布制成的充气球囊进行下颌固定.结果:使用该头颅固定枕进行手术与使用普通头枕固定治疗的手术比较,在成像次数、所受X线剂量、异常情况的发生上均较少,具有显著的优势.结论:该头颅气囊固定枕在神经介入手术中可缩短手术时间,减少辐射剂量,降低手术并发症的发生几率,值得临床推广.%Objective To develop a balloon-type head fixation pillow for interventional neuroradiology operation.Methods Some radiotransparent sponge with high elasticity and strength and some nonopaque cloth with high skin compatibility were employed to make pillow base adaptable to the posterior fossa, neck and shoulder. A inflatable balloon made of anti-tensile airtight nylon was used to fix the underjaw.Results The fixation pillow gained advantages over the common one in imaging times, X-ray exposure dose and abnormal condition.Conclusion The head fixation pillow may decrease operating time, exposure dose and complications during interventional neuroradiology operation, and thus is worth popularizing clinically.
