To create, distribute, and evaluate the efficacy of a portable, cost-effective 3D-printed laparoscopic trainer for surgical skills development.
The UCI Trainer (UCiT) laparoscopic simulator was developed via computer-aided designs (CAD), which were used to 3D-print the UCiT. Once assembled, a tablet computer with a rear-facing camera was attached for video and optics. Four institutions were sent the UCiT CAD files with a 3D-printer and instructions for UCiT assembly. For a comparison of the UCiT to a standard trainer, peg transfer and intracorporeal knot tying skills were accessed. These tasks were scored, and participants were asked to rate their experience with the trainers. Lastly, a questionnaire was given to individuals who 3D-printed and assembled the UCiT.
We recruited 25 urologists; none had any 3D-printing experience. The cost of printing each trainer was $26.50 USD. Each institution used the Apple iPad for optics. Six of eight participants assembled the UCiT in < 45 minutes, and rated assembly as somewhat easy. On objective scoring, participants performed tasks equally well on the UCiT vs the conventional trainer. On subjective scoring, the conventional trainer provided a significantly better experience vs the UCiT; however, all reported that the UCiT was useful for surgical education.
The UCiT is a low cost, portable training tool that is easy to assemble and use. UCiT provided a platform whereby participants performed laparoscopic tasks equal to performing the same tasks on the more expensive, nonportable standard trainer.
制作、分发并评估一种用于手术技能培养的便携式、经济高效的3D打印腹腔镜训练器的效果。
通过计算机辅助设计（CAD）开发了加州大学欧文分校训练器（UCiT）腹腔镜模拟器，并用其3D打印UCiT。组装完成后，连接一台带后置摄像头的平板电脑用于视频和光学。向四个机构发送了UCiT的CAD文件、一台3D打印机以及UCiT组装说明。为了将UCiT与标准训练器进行比较，对钉棒转移和体内打结技能进行了评估。对这些任务进行评分，并要求参与者对他们使用训练器的体验进行评价。最后，向3D打印并组装UCiT的人员发放了一份问卷。
我们招募了25名泌尿科医生；他们均无3D打印经验。打印每个训练器的成本为26.50美元。每个机构都使用苹果iPad进行光学操作。八名参与者中有六人在不到45分钟内组装好了UCiT，并认为组装 somewhat easy。在客观评分中，参与者在UCiT和传统训练器上完成任务的表现相当。在主观评分中，传统训练器提供的体验明显优于UCiT；然而，所有人都报告称UCiT对手术教育有用。
UCiT是一种低成本、便携式的训练工具，易于组装和使用。UCiT提供了一个平台，参与者在该平台上执行腹腔镜任务的表现与在更昂贵、非便携式的标准训练器上执行相同任务的表现相当。
