Abstract

BackgroundDuring laparoscopic surgeries, laparoscopes are inserted through a trocar port into the body cavity, which is then insufflated with carbon dioxide. Laparoscope lens clarity frequently becomes compromised via condensation or smearing of blood and adipose. This problem is well-known in the field, yet a viable in vivo solution has yet to address the issue and be successfully clinically adopted.Research DesignA structured cadaveric study evaluated the cleaning performance and clinician satisfaction with a novel laparoscope lens cleaning device against 2 gold-standard lens cleaning products. The novel device was also tested in a live animal porcine model to assess cleaning performance in a warm body environment qualitatively. The validation in the porcine model did not have the same evaluation process and comparison with other lens clearing methods as the cadaveric experiment.ResultsCleaning events were timed individually and analyzed post hoc. Average times to clean scopes for the novel device, Clearify™, and Fred™ Anti-Fog solution were 5 ± 5, 16 ± 7, and 14 ± 6 seconds, respectively. In 100 cleaning events with the novel device, the laparoscope was removed from the body zero times, with an average of 2 ± 1.29 cleaning actuations per event. Clearify™ and Fred™ Anti-Fog were removed from the body 102 and 116 times, with an average number of cleaning actuations of 1.07 ± 0.26 and 1.19 ± 0.53 per event, respectively. In the live porcine model, the novel device consistently cleared all debris deposited on the lens, including fog, tissue, blood, and bile fluid.ConclusionThis study demonstrates the novel device's reduction in cleaning duration and scope removals compared to gold-standard technologies, suggesting a potential for improved workflow and reduced intra-operative interruptions.

一种新型的“挡风玻璃雨刷”在尸体和活猪模型的腹腔镜验证。
背景:在腹腔镜手术中,腹腔镜通过套管针端口插入体腔,然后向体腔注入二氧化碳。腹腔镜镜头的清晰度经常因凝结或涂抹血液和脂肪而受到损害。这个问题在这个领域是众所周知的,但是一个可行的体内解决方案还没有解决这个问题,并被成功地应用于临床。研究设计一项结构化的尸体研究评估了一种新型腹腔镜晶状体清洁装置与2种金标准晶状体清洁产品的清洁性能和临床医生的满意度。该新型装置还在活体猪模型中进行了测试,以定性地评估在温暖身体环境中的清洁性能。猪模型的验证没有与尸体实验相同的评估过程和与其他晶状体清除方法的比较。结果每个清洗事件分别计时,事后分析。对于新型设备Clearify™和Fred™Anti-Fog solution,清洗范围的平均时间分别为5±5、16±7和14±6秒。在使用该新型装置的100次清洗中,腹腔镜从身体取出的次数为0次,平均每次清洗次数为2±1.29次。Clearify™和Fred™Anti-Fog分别从机体中去除102次和116次,每次清洗的平均次数分别为1.07±0.26次和1.19±0.53次。在活猪模型中,这种新型装置能够持续清除晶状体上沉积的所有碎片,包括雾、组织、血液和胆汁液。该研究表明,与金标准技术相比,新型设备减少了清洁时间和切除范围,这表明有可能改善工作流程并减少术中中断。

期刊介绍: Surgical Innovation (SRI) is a peer-reviewed bi-monthly journal focusing on minimally invasive surgical techniques, new instruments such as laparoscopes and endoscopes, and new technologies. SRI prepares surgeons to think and work in "the operating room of the future" through learning new techniques, understanding and adapting to new technologies, maintaining surgical competencies, and applying surgical outcomes data to their practices. This journal is a member of the Committee on Publication Ethics (COPE).
