摘要

目的

设计放置缝针的磁吸弯盘，探讨其在外科手术中的应用效果。

方法

设计的磁吸弯盘包括弯盘本体、缝针平台和永磁铁3个部分。选择2021年9月大连大学附属中山医院和上海市某三级甲等综合医院的40名医师及40名护士作为研究对象（1名医生搭配1名护士），采用随机数字表法分为观察组和对照组，每组40人。观察组使用磁吸弯盘放置缝针，对照组使用普通弯盘放置缝针，每个弯盘放置12根缝针。每名医生在皮肤模型上缝合60次。比较2组夹针精准率、夹针时间、脱针率、缝针丢失率、缝针清点时间和医护人员满意度。

结果

观察组夹针精准率高于对照组，夹针时间、缝针清点时间短于对照组，缝针丢失率低于对照组，医护人员满意度评分高于对照组，差异均有统计学意义（

0.05）。2组脱针率比较，差异无统计学意义（

0.05）。

结论

外科手术中使用磁吸弯盘能提高夹针精准率及医护人员满意度，缩短夹针时间及缝针清点时间，降低缝针丢失率，手术安全性较高。

Abstract

Objective

To design a magnetic curved disc for placing suture needles and explore its application effect in surgery.

Methods

The designed magnetic curved disc consisted of three parts： the curved disc body，the suture needle round table and permanent magnet. A total of 40 doctors and 40 nurses（1 doctor with 1 nurse） from Zhongshan Hospital Affiliated to Dalian University and a tertiary Grade A comprehensive hospital in Shanghai in September 2021 were selected， and randomly divided into the observation group and the control group， with 40 cases in each group. The observation group placed suture needles in the curved magnetic disc and the control group placed suture needles in the ordinary curved disc， with 12 suture needles in each curved disc. Each doctor sutured 60 times on the skin model. The precision rate of needle clamping， needle clamping time， needle removal rate，needle loss rate， needle counting time and medical staff satisfaction were compared between the two groups.

Results

The precision rate of needle clamping in the observation group was higher than that in the control group， and the needle clamping time and needle counting time were shorter than those in the control group， the needle removal rate was lower than that in the control group， and the medical

staff satisfaction was higher than that in the control group， with statistically significant differences （

0.05）. There was no significant difference in the needle loss rate between the two groups （

0.05）.

Conclusion

The use of magnetic curved disc in surgery can improve the precision rate of needle clamping and the medical staff satisfaction， shorten the needle clamping time and needle counting time， and reduce the needle loss rate， with high safety of surgery.
