目的 自制介入手术机床约束床单并评价其应用效果。方法 介入手术机床约束床单由床单本体、绑带、活动带、四肢固定带组成。便利选取浙江省某三级甲等综合医院微创介入科行全身麻醉下颅内动脉机械取栓术的100例急性缺血性卒中患者,其中2022年6月—10月的50例患者为试验组,使用介入手术机床约束床单;2022年1月—5月的50例患者为对照组,不进行约束。比较两组患者入导管室至股动脉穿刺时间、术中不良事件发生率的差异。结果 试验组入导管室至股动脉穿刺时间（15.60±3.34）min小于对照组（25.98±5.50）min,差异具有统计学意义（t=-11.406,P<0.001）;两组均未发生不良事件。结论 介入手术机床约束床单操作安全,缩短患者入导管室至股动脉穿刺时间。
Objective To design the machine bed restraint sheets for interventional surgery and evaluate the application effects. Methods Machine bed restraint sheets for interventional surgery was composed of sheet body,straps,mobile straps,and extremity fixation straps. We conveniently selected 100 patients with acute ischemic stroke who underwent mechanical intracranial thrombectomy under general anesthesia in minimally invasive interventional department of a Grade-Ⅲ general hospital in Zhejiang Province. 50 patients from June to October 2022 were selected as experimental group and the restraint bed sheets were used. 50 patients from January to May 2022 were selected as control group without restraint. The time from catheter lab to femoral artery puncture and the incidence of intraoperative restraint-related adverse events were compared between the two groups. Results The time from catheter lab to femoral artery puncture of experimental group was（15.60±3.34）min which was shorter than that of control group（25.98±5.50）min. The difference was statistically significant（t=-11.406,P<0.001）. No restraint related adverse events occurred in both groups. Conclusion The machine bed restraint sheets are safety to operate,which can shorten the time from catheter lab to femoral artery puncture.
