Abstract

Simulated bones play a crucial role in surgical training, yet existing models vary in fidelity and cost. We developed a novel, low-cost, high-quality SLA 3D-printed metacarpal to enhance hand trauma training.

Our design incorporates novel cortico-medullary differentiation to replicate the tactile feedback experienced when drilling through real bone.

Our device was tested across 3 centres with 17 hand surgeons providing feedback. Overall surgeons highly rated our device, with it outperforming homogenous control simulators. All surgeons agreed that it had the potential to enhance surgical training.

We have addressed the single use aspect of our devices by partnering with a plastic upcycling firm to repurpose used simulators, minimising landfill waste.

We look forward to implementing our device in surgical training, whilst further improving it via the addition of built in fractures and a soft tissue envelope.

新型掌骨模拟器的验证研究：手部骨折固定训练的下一步

模拟骨骼在外科训练中起着至关重要的作用，然而现有的模型在保真度和成本上各不相同。我们开发了一种新颖、低成本、高质量的SLA 3d打印掌骨，以加强手部创伤训练。我们的设计结合了新的皮质-髓质分化，以复制钻穿真实骨骼时所经历的触觉反馈。我们的设备在3个中心进行了测试，17位手外科医生提供了反馈。总的来说，外科医生对我们的设备评价很高，它的表现优于同类控制模拟器。所有的外科医生都认为它有可能提高外科训练。通过与塑料升级回收公司合作，我们解决了设备的一次性使用问题，重新利用使用过的模拟器，最大限度地减少垃圾填埋。我们期待在外科训练中实施我们的设备，同时通过增加内置骨折和软组织包膜进一步改进它。
