背景：手术工作流程记录的一个关键部分是识别所使用的仪器。我们提出了一种基于射频识别 (RFID) 的方法，用于实时跟踪腹腔镜器械。方法：该系统由带有 RFID 标签的器械和位于 Mayo 支架上的天线单元组成。为了进行可靠性分析，将 RFID 跟踪数据与 10 例腹腔镜胆囊切除术中器械变化的围手术期视频数据（器械应用检测的参考标准）的评估进行了比较。当标记的器械位于梅奥展台上时，它被称为“未使用”。一旦将其交给外科医生，它就被认为是“正在使用”。分析了时间错误计数（“正在使用”的器械数量不正确）。外科医生和手术护士在每次手术后完成一份调查问卷，以进行单独的系统评估。结果：总共 110 种不同的器械应用（“使用中”与“未使用”）符合分析条件。没有发生RFID标签故障。 RFID检出率与仪器有效使用期限一致。仪器检测延迟为 4.2 +/- 1.7 秒。时间错误计数的最高百分比发生在连续应用凝固电流的阶段。外科医生普遍对该系统的评价优于擦洗护士（P=0.54）。结论：本研究成功证明了基于RFID的实时仪器检测的可行性，在腹腔镜胆囊切除术中检测结果可靠。因此，RFID 技术有潜力成为外科手术流程识别的一个有价值的附加工具，可以在未来为外科医生提供依赖情况的帮助。 (C) 2013 Elsevier Inc. 保留所有权利。
Background: A key part of surgical workflow recording is recognition of the instrument in use. We present a radiofrequency identification (RFID)-based approach for real-time tracking of laparoscopic instruments.Methods: The system consists of RFID-tagged instruments and an antenna unit positioned on the Mayo stand. For reliability analysis, RFID tracking data were compared with the assessment of the perioperative video data of instrument changes (the reference standard for instrument application detection) in 10 laparoscopic cholecystectomies. When the tagged instrument was on the Mayo stand, it was referred to as "not in use."Once it was handed to the surgeon, it was considered to be "in use."Temporal miscounts (incorrect number of instruments "in use") were analyzed. The surgeons and scrub nurses completed a questionnaire after each operation for individual system evaluation.Results: A total of 110 distinct instrument applications ("in use"versus "not in use") were eligible for analysis. No RFID tag failure occurred. The RFID detection rates were consistent with the period of effective instrument application. The delay in instrument detection was 4.2 +/- 1.7 s. The highest percentage of temporal miscounts occurred during phases with continuous application of coagulation current. Surgeons generally rated the system better than the scrub nurses (P=0.54).Conclusions: The feasibility of RFID-based real-time instrument detection was successfully proved in our study, with reliable detection results during laparoscopic cholecystectomy. Thus, RFID technology has the potential to be a valuable additional tool for surgical workflow recognition that could enable a situation dependent assistance of the surgeon in the future.
