Description

牙髓^ L器 技术领域
本实用新型涉及一种医疗器械， 特別是一种牙科设备， 一种牙髓检视器。 背景技术
牙医在为患者治疗时一般采用开髓引流、 切除止痛方法， 即首先在牙齿上制备 窝洞形、 开放牙髓腔， 然后清理根管， 打通根尖孔， 以减除内压并引流炎性渗出物， 接着切除清理龋坏组织并消毒窝洞， 还要进行消毒止痛， 最后在窝洞洞底覆盖盖髓 剂并用银汞合金或复合树脂充填。 但牙医在制备窝洞、 开放牙髓腔及清理根管等手 术时， 只是以其有限的可视范围和以往的经验进行操作， 严重影响手术顺利进行， 甚至造成手术效果不理想。
为此， 很多厂商开发出口腔内窥镜， 这些口腔内窥镜包括一塑料壳体， 形状与 普通电动牙刷类似， 其前端设有摄像头和 LED灯， 放入口腔时， 摄像头尺寸过大， LED灯角度太偏， 无法照射到牙髓洞深处， 反而牙齿外部被照得很亮、发白， 牙齿内 外黑白反差大， 摄像头拍摄的影像， 根本无法看清牙髓洞内部的纹理细节。 如果釆 用增大功率来提高 LED灯的照度， 还是解决不了问题， 反而会让 LED灯发热而烧坏。 另外， 德国的蔡司 （ Ze i s s )公司也开发了口腔根管显微镜， 该显微镜是把摄镜头 放在距牙髓洞底 15CM— 25CM左右的口腔外， 然后利用高强度冷光照明灯聚焦在牙髓 洞内， 即可拍摄出清晰影像， 但该显微镜的摄像头由于置于口腔外， 让其对焦在牙 髓洞上难度较大， 使用时患者只要稍微一动或者显 t镜稍微被移动， 即拍摄不到牙 髓洞， 必须重新调整摄像头焦距和冷光照明灯的聚焦点， 使用不方便， 十分麻烦， 而且冷光照明灯同时置于口腔外， 到牙髓洞距离加长， 照射角度变小， 要让冷光可 以直射入牙髓洞底部， 根据照度与距离平方成反比， 所需功率必须大的多； 加上其 采用长焦距镜头等制造， 成本和日常维护、 维修成本都很高， 大大降低消费者的购 买意欲， 市场难以推广、 普及， 患者使用所支付费用也贵， 无形中增加了患者负担。 发明内容 为解决上述问题， 本实用新型的提供一种制作成本低、 工作性能稳定且具有高 清拍摄效果的牙髄检视器。
本实用新型是通过以下技术方案来实现的：
一种牙髓检视器， 包括有可置于口腔内的摄像头和照明装置， 其中： 还包括有 窥视管， 所述窥枧管为中空管状结构， 位于摄像头的镜头的前方， 釆用不透光或半 透光材料制成； 所述窥视管的中心线与摄像头的镜头中心线方向一致， 窺枧管的中 空腔形成摄像头的入射光通道； 所述照明装置安装在所述窥视管外周， 并安装于所 述摄像头上方。
所述照明装置紧挨着所述窥视管设置， 且一并安装在所述摄像头的镜头前方。 优选地， 所述窥视管内径范围为 0. 5隱至 3mm 。
所述窥视管内径为 1. 2隱 。
所述照明装置是 LED灯组， 由一个以上超高亮度的白色 LED灯组成， 并采用连 接为一体的环形结构封装在电路板上， 且所述窥视管穿过所述 LED灯组的环形结构 中央。
所述超高亮度的白色 LED灯有 8至 11只。
本实用新型的有益效果在于： 由于本实用新型釆用了窥视管， 所述寇视管为中 空管状结构， 位于摄像头的镜头的前方， 釆用不透光材料制成； 所述窥视管的中心 线与摄像头的入射光线方向一致， 窥视管的中空腔形成摄像头的入射光通道， 上述 技术方案使得光线更聚拢， 到达牙齿距离更近， 并可垂直照入牙髄腔底部， 进入的 光量大大增强， 可看清楚牙髄腔内纹理与钙化部分， 而直径很小的窥视管又仅允许 牙髓腔底部影像通过， 摄像头即可直接取得牙髓腔底部的清晰影像， 解决了黑暗的 牙髓腔底部与过于白亮的牙齿表面影像黑白对比太大导致无法获取清晰影像的问 题， 加上窥视管可有效阻挡 LED灯组发出的光线直接进入摄像头内， 避免所需影像 变暗现象， 保证清晰的拍摄效果， 而且金属壳身、 金属套结构能有效、 快速地将热 量散发掉， 保证工作性能更稳定、 不易烧坏、 使用寿命更长， 再加上本产品生产成 本低， 在市场具有很强的竟争力， 有利的市场开拓、 推广和普及。 附图说明
