【摘要】：目的经超声引导下的胎儿脐静脉穿刺技术是产前诊断与胎儿宫内疾病诊断与治疗的主要技术,但手术风险较大。本篇设法用刚从母体娩出的胎盘、脐带、橡胶手套等材料制作一种方法简便,价格低廉,更能模拟真实情况的实体模型,用来训练操作者的空间立体感、手眼协调能力及穿刺技能。方法选择刚从母体娩出的胎盘、脐带、猪皮、8号橡胶手套、细皮条、自来水、容器等材料来制作一种模拟中晚期妊娠宫内环境的实体模型。用充满自来水的水囊模拟羊膜腔环境、胎盘附着在水囊壁、连接胎盘的脐带漂浮于水囊内,脐静脉就作为操作者的穿刺目标。结果用胎盘、脐带、橡胶手套等材料制作的模型,可以为操作者提供更为逼真的胎儿脐静脉穿刺术练习场景,培养操作者的穿刺技能:如超声介导下实时监控穿刺针的进退、穿刺方向与深度、穿刺目标的准确性,更好地培训穿刺者的手眼协调能力与操作技能。结论本模型能为操作者提供胎儿脐静脉穿刺技术更逼真的穿刺场景与培训工具。
[Abstract]:Objective Ultrasound-guided fetal umbilical vein puncture is the main technique of prenatal diagnosis and fetal intrauterine disease diagnosis and treatment, but the surgical risk is high. This paper tries to use the placenta, umbilical cord, rubber gloves and other materials that have just been delivered from the mother to make a simple, inexpensive, more realistic solid model to train the operator's spatial stereosyncrasies. Hand-eye coordination and puncture skills. Methods the placenta, umbilical cord, pig skin, rubber glove No. 8, fine leather, tap water, container and other materials were selected to make a solid model of the intrauterine environment of the third trimester of pregnancy. The amniotic cavity environment was simulated by water filled with water. The placenta was attached to the water capsule wall and the umbilical cord attached to the placenta was floating in the water sac. The umbilical vein was used as the target of the operation. Results using placenta, umbilical cord, rubber gloves and other materials, the model can provide operators with more realistic practice scenes of fetal umbilical vein puncture, and train the operator's puncture skills, such as real-time monitoring the advance and retreat of the puncture needle under the guidance of ultrasound. Puncture direction and depth, accuracy of puncture target, better training of hand-eye coordination and operational skills. Conclusion this model can provide operators with more realistic puncture scene and training tools for fetal umbilical vein puncture.
