摘要

背景:关节腔穿刺术或关节腔液体抽吸术必须进入关节。如果关节治疗操作不当,可能会导致患者出现本可避免的问题,如损伤关节周围的肌肉、肌腱和血管。超声波的使用已成为该程序的黄金标准,并被证明是技能学习过程中的辅助工具。然而,能否成功使用这种设备,尤其是在腕部等小关节上,取决于临床医生能否识别指导这些手术的关键标志。事实证明,在对真正的病人实施手术之前,任务训练器是医生练习和准备手术的有效方法。然而,目前的解决方案存在购买成本高、与超声成像不兼容、可重复使用性低等缺点。此外,由于这种手术并不经常进行,医疗机构可能没有足够的空间或资源在护理点安装这种设备。本研究旨在通过开发用于腕关节入路训练的 DIY 超声波兼容任务训练器来弥补现有差距:我们开发了一种新型超声波兼容腕关节模型,该模型可由可持续材料和可重复使用的部件制成,从而降低了购置成本和对环境的影响。我们的模型是利用小批量生产方法制作的,由三维打印骨骼和超声波兼容明胶混合物组成。每次练习后,它都可以很容易地重新制作,去除传统模型在超声波下可见的针迹。通过对模拟解剖结构进行像素亮度分析和目视检查,测试了该模型的超声特性:我们的研究结果表明了该模型在制作、实践和超声波兼容性方面的优势和局限性。虽然未来的工作需要将相同的技能传授给病人,但事实证明,这种可重复使用和复制的模型在向专家展示时,能成功地表现重要解剖结构的物理特征和超声波轮廓。在资源有限的临床模拟中心,这种新颖的 DIY 产品可以成为程序教学的有效替代品。

A do it yourself (DIY) point-of-care wrist ultrasound phantom for joint access training.

Background: Joint access is essential for arthrocentesis, or joint aspiration of fluids. Joint treatments that are not performed properly can result in avoidable patient issues such as damage to the muscles, tendons, and blood vessels surrounding the joint. The use of ultrasound has become the gold standard for this procedure and proven to be a support in the skill learning process. However, success with this equipment, particularly in small joints like the wrist, depends on a clinician's capacity to recognize the crucial landmarks that guide these procedures. Prior to executing on a real patient, task trainers have proven to be an effective way for doctors to practice and prepare for procedures. However, shortcomings of current solutions include high purchase costs, incompatibility with ultrasound imaging, and low reusability. In addition, since this is a procedure that is not performed frequently, there may not be space or resources available in healthcare facilities to accommodate one at the point of care. This study aimed to close the existing gap by developing a DIY ultrasound compatible task trainer for wrist joint access training.

Results: We developed a novel ultrasound compatible wrist joint model that can be made from sustainable materials and reusable parts, thus reducing the costs for acquisition and environmental impact. Our model, which was produced utilizing small-batch production methods, is made up of 3D-printed bones enclosed in an ultrasound-compatible gelatin mixture. It can be easily remade after each practice session, removing needle tracks that are visible under ultrasound for conventional phantoms. The ultrasonic properties of this model were tested through pixel brightness analysis and visual inspection of simulated anatomical structures.

Conclusion: Our results report the advantages and limitations of the proposed model regarding production, practice, and ultrasound compatibility. While future work entails the transfer to patients of the same skill, this reusable and replicable model has proven, when presented to experts, to be successful in representing the physical characteristics and ultrasound profile of significant anatomical structures. This novel DIY product could be an effective alternative to teach procedures in the context of resource-restrained clinical simulation centers.
