    摘要:

    目的:探讨单孔腹腔镜平台上不同类型器械的操作规律-方法:7名初级腹腔镜外科医师在单孔腹腔镜训练装置上采用随机顺序使用传统器械-双弯曲器械及可调弯曲器械进行双手传递和剪裁任务训练,每天3种器械每项任务训练2次,共训练5 d-第6天进行任务考核,并采用主观疲劳度量表调查每种类型器械对操作者造成的负担-结果:在双手传递任务中,双弯曲器械得分落后于其他2种器械[双弯曲器械(239.4 ± 11.9)分vs.传统器械(251 ± 7.40)分vs.可调弯曲器械(254.4 ± 4.6)分,P < 0.05)]-在剪裁任务中,可调弯曲器械的表现占据明显优势[传统器械(304 ± 41.4)分vs. 双弯曲器械(362.6 ± 33.2)分vs. 可调弯曲器械(405.4 ± 21.9)分,P < 0.05]-相对于传统器械,参与者均认为双弯曲器械和可调弯曲器械的熟练掌握需要付出更多精神和体力,需要更多努力;但付出的时间和绩效水平3种器械之间差异无统计学意义-和传统器械及双弯曲器械相比较,可调弯曲器械的表现更令参与者自信-结论:在单孔腹腔镜模拟训练中,和传统器械及双弯曲器械相比较,可调弯曲器械操作更有效-更容易被训练者掌握-

    Abstract:

    Objective:To study the operating law of different sets of instruments in laparoendoscopic single-site surgery. Methods:Seven laparoscopic-experienced participants were arranged to perform two basic tasks (peg transferring and pattern cutting) using conventional instruments,double-curved instruments and articulating instruments randomly in a modified simulator for 5 days (each instrument was trained for 2 times a day),and finally a test of the tasks were performed by each of the participants. In addition,the instruments of National Aeronautics and Space Administration Task Load Index (NASA-TLX) were completed to investigate the workload for the participants. Results:The task scores of double-curved instruments were worse than the other two sets of instruments in the task of peg transferring (double-curved instruments 239.4 ± 11.9 vs. conventional instruments 251.0 ± 7.4 vs. articulating instruments 254.4 ± 4.6,P < 0.05). The articulating instruments got the best performance in pattern cutting (conventional instruments 304.0 ± 41.4 vs. double-curved instruments 362.6 ± 33.2 vs. articulating instruments 405.4 ± 21.9,P < 0.05). The workload measured by NASA-TLX tool demonstrated that double-curved instruments and articulating instruments had a heavier workload compared with conventional instruments in mental demand,physical demand and effort. There was no significant difference on temporal demand and performance. Participants were more self-confident using articulating instruments compared with the other two sets of instruments. Conclusion:Articulating instruments is more effective and favorable than conventional and double-curved devices for laparoscopic-experienced surgeons in the laboratory setting of laparoendoscopic single-site surgery.
