Description

牙科注射模拟系统及其方法 技术领域
本发明涉及一种牙科注射模拟系统及其方法, 尤其关于一种利用光学定 位装置, 辅助追踪针筒与头模的方位, 确认学员注射麻药时施打的手势、 方 位是否正确, 避免人为主观的数值判定, 具公平及客观性, 提升分析数据的 精度。 背景技术
在牙科的门诊中, 经常为患者使用神经阻断麻醉, 最主要的目的便是避 免治疗过程中不舒服的感觉, 使整个治疗过程能顺利地完成。 由于神经阻断 麻醉术后须一到二个小时才会退去, 因此在这二个小时内, 患者嘴唇及脸频 会感觉麻麻。 与全身麻醉较, 神经阻断麻醉较具安全。 在台湾, 虽然没有正 式的统计报告, 但在注射神经阻断麻醉药后产生不舒服或意外的案例仍时有 所闻, 这表示牙科神经阻断麻醉仍有其风险, 不可掉以轻心。
牙科使用的麻醉方式包括吸入笑气、 静脉注射的镇静麻醉药, 以及吸入 性全身麻醉二种, 通常是用在身心障碍患者和不合作的儿童治疗上, 或少数 对看牙特别恐惧的民众。
然而, 目前牙科学员在学习口腔神经阻断麻醉的教学训练上, 是学员手 持注射装置在模型上进行模拟注射, 再由教师肉眼评估学员施打的手势、 方 位是否正确。
因为对用肉眼评估手势、 方位的判断往往会因人而异, 会显得过于主观, 无法避免人为主观的分数判定; 且无法使学员于第一时间知道错误发生并调 整施术的方法, 也无法评估当下麻药注射过程入针点及到针点偏移, 检视该 次施术有无符合标准, 决定该次施术正确性及优劣程度, 也无法完整储存所 有施术过程评估记录, 产生完整学习历程, 学员无法很完整清楚自己错误之 处。
现有技术中, 已存在一些技术是互动式用以追踪医疗器材的位置, 如美 国专利第 5,617,857 号 "具有互动式的医疗器材的成像系统与方法 (Imaging System Having Interactive Medical Instruments And Methods)",其揭示一种成像 的系统及方法。 此成像系统包括一医疗器材主体以及一发射可被侦测的能源 的发射器。 进一步利用一侦测器及处理器, 以侦测该医疗器材的位置。
美国专利第 6,640,128 号"用于辅助导航的牙医治疗方法及装置 (Method And Device For The Navigation-Assisted Dental Treatment)" ,其揭示一种辅助牙 医治疗的方法。 首先, 对病人的牙齿及或下颚区域提供一组三维的体积资料 组。 一电脑辅助导航或寻迹系统利用该体积资料组记录该病人的牙齿或下颚 区域。 相对于该电脑辅助的导航或寻迹系统, 医疗仪器或装置将会被记录。
然而, 所述的现有技术无法搭配现有的牙科装备功能升级, 例如其无法 搭配现有的常用牙科手术台以及手钻机(手工具) , 且所述的现有技术无法 根据使用者的习惯进行操作的调整, 在装置的定位以及矫正上亦不便于藉助 现有的个人电脑架构, 造成更换系统的费用昂贵, 进而限制了市场的可能性。
本案发明人于中国台湾省申请案号 097113976" 牙科临床与教学训练模 拟追踪系统及其评鉴方法" , 也揭露一种能使用低成本的摄影机建立三维手 术器械的运动追踪器, 能利用现有装置加以升级, 且能配合使用者的操作习 惯(例如左手或右手) , 并以自动化方式来改善传统以人工比对的方法, 对 牙科医师训练时的准确性及便利性提升很多。
然而, 所述的辅助训练装置皆无提供相当的装置应用于口腔麻醉的教学 训练上。 爰此, 本案发明人透过已揭露的定位演算法, 提供追踪针筒与头模 的方位, 用以评估确定学员注射麻药时施打的手势、 方位是否正确, 且使用 拟真的元件, 使施打的过程尽可能与临床施打的感受接近, 使牙医在真实医 疗行为注射神经阻断麻醉药时, 可使病患不舒服或意外风险降到最低。 发明内容
于是, 为解决上述的缺点, 本发明的目的在于提供一种牙科注射模拟系 统及其方法, 利用光学式追踪的方式进行定位, 配合空间定位技术的使用来 简化影像处理的过程, 而可以利于追踪针筒与头模的方位并将使用历程加以 储存, 方便让日后可针对使用历程的疏失加以改进, 产生完整数据分析历程, 避免人为主观的数值判定, 具公平及客观性, 提升评估精度。
本发明的另一目的是提供一种牙科注射模拟系统及其方法, 除了可直接 用于牙医师临床的训练、 操作以及评比上, 透过拟真的元件, 使施打的过程 尽可能与临床施打的感受接近。
本发明提供了一种牙科注射模拟系统, 包括:
一定位单元;
一针筒, 与该定位单元做相对运动, 并具有多个定位点; 以及
一光学分析装置, 具有一资讯处理单元、 一显示单元及一光学定位模块, 该显示单元及该光学定位模块电连接该资讯处理单元, 该光学定位模块具有 多个光学截取元件, 光学扫描该定位单元及该针筒的定位点并取得数据输出 至该资讯处理单元。

(6)将该分析结果输出并显示于该显示单元。
本发明的优点在于, 利用定位演算法, 提供追踪针筒与头模的方位, 用 以评估确定学员注射麻药时施打的手势、 方位是否正确, 且使用拟真的元件, 使施打的过程尽可能与临床施打的感受接近, 使牙医在真实医疗行为注射神 经阻断麻醉药时, 可使病患不舒服或意外风险降到最低。 附图说明
