Abstract:
Restricted mouth opening (trismus) is one of the most common complications following head and neck cancer treatment. Early initiation of mouth-opening exercises is crucial for preventing or minimizing trismus. Current methods for these exercises predominantly involve finger exercises and traditional mouth-opening training devices. Our research group successfully designed an intelligent mouth-opening training device (IMOTD) that addresses the limitations of traditional home training methods, including the inability to quantify mouth-opening exercises, a lack of guided training resulting in temporomandibular joint injuries, and poor training continuity leading to poor training effect. For this device, an interactive remote guidance mode is introduced to address these concerns. The device was designed with a focus on the safety and effectiveness of medical devices. The accuracy of the training data was verified through piezoelectric sensor calibration. Through mechanical analysis, the stress points of the structure were identified, and finite element analysis of the connecting rod and the occlusal plate connection structure was conducted to ensure the safety of the device. The findings support the effectiveness of the intelligent device in rehabilitation through preclinical experiments when compared with conventional mouth-opening training methods. This intelligent device facilitates the quantification and visualization of mouth-opening training indicators, ensuring both the comfort and safety of the training process. Additionally, it enables remote supervision and guidance for patient training, thereby enhancing patient compliance and ultimately ensuring the effectiveness of mouth-opening exercises.
摘要:
张口受限(三联)是头颈部癌症治疗后最常见的并发症之一。尽早开始张嘴练习对于预防或减少三嘴至关重要。这些练习的当前方法主要涉及手指练习和传统的张嘴训练设备。我们的研究小组成功设计了一种智能张嘴训练设备(IMOTD),解决了传统家庭训练方法的局限性,包括无法量化张嘴练习,缺乏指导训练导致颞下颌关节损伤,训练连续性差导致训练效果差。对于这个装置,为了解决这些问题,引入了交互式远程指导模式。该设备的设计重点是医疗设备的安全性和有效性。通过压电传感器标定验证了训练数据的准确性。通过力学分析,确定了结构的应力点,并对连接杆和咬合板的连接结构进行了有限元分析,以确保装置的安全性。与传统的张口训练方法相比,研究结果通过临床前实验支持智能设备在康复中的有效性。这种智能设备有助于张口训练指标的量化和可视化,确保培训过程的舒适性和安全性。此外,它为患者培训提供了远程监督和指导,从而提高患者的依从性并最终确保张嘴练习的有效性。
