开颅手术翻转头皮瓣遮挡器的研制及临床应用研究

Study on development and clinical application of flip scalp flap blocking device for craniotomy

目的应用自行研制的开颅手术翻转头皮瓣遮挡器改善开颅手术翻转头皮瓣的固定效果。方法选取2008年3月至2011年10月期间，外伤性硬脑膜外血肿患者120例，按照随机数字表法将其分为观察组和对照组，其中60例应用自行研制的翻转头皮瓣遮挡器固定（观察组）和60例应用常规弹簧钩固定（对照组）。观察两组患者手术经历时间、术中调整头皮固定装置次数和手术医生的满意度。结果两组在患者手术时间、术中装置调整次数、手术医师满意度三方面差异均有统计学意义（P〈0．05），存在显著性差异。结论开颅手术翻转头皮瓣遮挡器设计原理确切，遮挡固定效果可靠，使用简便，手术野暴露充分，避免术中反复多次调整固定装置，节约手术时间，显著提高手术医师满意度，避免因头皮瓣固定不当影响手术操作而导致的烦躁心理。

Objective To observe the effect of self-developed flip scalp flap blocking device for craniotomy. Methods 120 patients with traumatic epidural hematoma were selected from March 2008 to April 2011 and randomly divided into observation and control groups according to a random number table grouping principles. 60 patients in control group were used the conventional spring hooks to fix the flip scalp flap in craniotomy, the other 60 patients in observation group were used self - developed flip scalp flap blocking device. The opera- tion time, the times of the scalp flap fixation device adjusted during the operations and the satisfaction degree of surgeons were ob- served. Results There were significant differences in operative time, intraoperative device calibration frequency, surgeons satisfaction be- tween two groups （P 〈 0. 05） . Conclusions The design principle and effects of flip scalp flap blocking device is exact and reliable. The device is quite simple to use which can make operative field exposure fully and neatly, avoid repeated adjustment fixtures during operation, save operation time, improve the satisfaction degree of surgeons, and avoid improper scalp flap fixation causing surgeon psychological upset.
