Description

一种自主低摩擦托槽
技术领域
本发明涉及医疗器械领域， 特别是涉及一种自主低摩擦托槽。 背景技术
目前国内外巿场上现有的正畸托槽从临床结扎方式可区分为结 扎型托槽和自锁型托槽二类 (结扎型： 牙弓丝与托槽之间釆用结扎丝 或弹性结扎圈结扎， 使牙弓丝与托槽槽沟之间紧密接触， 因而摩擦力 较大， 所有传统托槽均属于结扎型， 如图 1所示。 自锁型： 牙弓丝不 需要结扎丝结扎，而是在托槽槽沟唇颊向开口处用一块可滑动或翻转 的金属盖将矫治弓丝封闭在槽沟之中，此封闭盖与槽沟形成的管腔对 矫正弓丝没有束缚力， 因而摩擦力小， 所有自锁托槽均具有此特点）。 自锁托槽又分为主动自锁和被动自锁两类， 区别在于被动自锁的封闭 盖没有弹性设计， 自始至终不会对矫正弓丝主动施力； 而主动自锁的 封闭盖有弹性设计， 当矫正弓丝达到一定尺寸时， 弹性封闭盖可以对 矫正弓丝主动施力。 目前国内巿场上的自锁托槽， 大多为进口产品， 或国外设计， 不仅价格昂贵， 而且在临床使用中还会经常出现封闭盖 因食物 ^渣镶嵌、 受力变形等因素而不能打开或不能合上的问题。 发明内容
(一） 要解决的技术问题
本发明要解决的技术问题是如何在不改变临床医生的传统操作 方式前提下实现降低摩擦力的效果，并改变现有自锁托槽上存在的后 期治疗不能实现精确控制， 以及封闭盖经常会因食物残渣镶嵌或变形 发生不能打开或打开后不能合上的缺陷。
(二）技术方案
为解决上述技术问题，提供一种自主低摩擦托槽，包括托槽基体， 位于网底上， 所述托槽基体上具有两个侧壁， 所述两个侧壁与所述托 槽基体之间形成主弓丝槽， 所述两个侧壁的上端分别具有结扎翼， 所 述两个侧壁的外表面设置有斜坡，使得侧壁沿所述托槽基体向所述结 扎翼的方向上壁厚逐渐减小，在所述结扎翼与所述侧壁的连接处¾置 有凹陷。
优选地， 在所述结扎翼的上端设置有牙位标记。
优选地， 所述牙位标记为数字、 凸点或者凹点。
优选地， 所述四陷为弧形凹陷。
优选地， 所述弧形凹陷的直径为： 0.2mm-0.3mm。
优选地， 所述斜坡的倾角为： 20-60°。
优选地，,所述自主低摩擦托槽还包括设置于所述主弓丝槽中的细 弓丝， 其直径 Φ < 0.016" 。
优选地，所述自主低摩擦托槽还包括设置于所述主弓丝槽中的粗 弓丝， 其直径 Φ > 0.017" 。
优选地，所述自主低摩擦托槽还包括设置于所述主弓丝槽中的方 丝， 截面尺寸为 0.017" X 0.025" 。
优选地， 所述网底为金属网底。
(三）有益效果
通过对现有普通托槽的改进，在不改变临床医生的传统操作方式 前提下实现降低摩擦力的效果，并改变了现有自锁托槽上存在的后期 治疗不能实现精确控制， 以及封闭盖经常会因食物残渣镶嵌或变形发 生不能打开或打开后不能合上的缺陷。 附图说明
图 1是现有普通托槽的主动结扎状态示意图；
图 2是依据本发明实施方式的自主低摩擦托槽的结构示意图； 图 3是依据本发明实施方式的自主低摩擦托槽早期被动结扎状态 示意图；
图 4是依据本发明实施方式的自主低摩擦托槽后期主动结扎状态 示意图。
其中， 1 : 托槽基体； 2: 网底； 3: 主弓丝槽； 4: 结扎翼； 5-1 : 斜坡； 5-2: 弧形凹陷； 6: 牙位标记； Ί', 纵轴线。 具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细 描述。 以下实施例用于说明本发明， 但不用来限制本发明的范围。
如图 2所示，本发明提供了一种自主低摩擦托槽，包括托槽基体 1、 金属网底 2、 主弓丝槽 3、 结扎翼 4、 用于结扎导入的斜坡 5-1及弧形凹 陷 5。 托槽基体 1位于金属网底 2上， 位于托槽基体 1上的两个侧壁与托 槽基体 1形成了主弓丝槽 3， 在两个侧壁的上端分别具有结扎翼 4。 在 两个侧壁的外表面设置用于结扎导入的斜坡 5-1及弧形凹陷 5-2。 斜坡 5-1设置为由托槽基体 1向结扎翼 4的方向上壁厚逐渐减小。 与现有技 术的普通托槽相比，本实施例将普通托槽侧壁的垂直外侧面改成了用 于结扎导入的斜坡 5-1及位于坡底的弧形 ΙΗ陷 5-2。在结扎翼 4的上端设 置有牙位标记 6， 用于区分托槽龈颌向位置。 牙位标记 6可以为数字、 凸点或者四点。 在侧壁的中部设置有纵轴线 7, 用于托槽临床粘结时 参照。 弧形凹陷 5-2的直径可以在下述范围内： 0.2mm ~ 0.3mm; 斜 坡 5-1的倾角可以在下述范围内： 20 ~ 60度。
将该实施例的自主低摩擦托槽按照与普通托槽一样的粘结方式 粘结在牙面上，待粘结剂固化后将小于 00.016〃 的细弓丝或者镍钛圆 丝置入主弓丝槽 3内， 用传统结扎方式进行结扎。 如图 3所示由于设计 了用于结扎导入的斜坡 5-1 , 结扎丝难以在斜坡中途固位， 只能顺着 斜坡 5- 1滑入坡底的弧形凹陷 5-2固位， 因此结扎丝与主弓丝之间没有 任何束缚力， 形成被动结扎状态， 可以让牙齿快速移动， 完全达到普 通自锁托槽的功能。
在治疗的后期阶段， 临床上往往需要对牙齿进行精确控制。 该实 施例的自主低摩擦托槽只需将主弓丝换成 0 > 0.017" 或者 0.017" X 0.025" 以上的标准方丝， 按传统结扎方式进行结扎。 此时结扎丝与 主弓丝之间产生紧密束缚， 如图 4所示， 处于主动结扎状态， 临床医 师可以对牙齿实现精细调整和控制。
对目前临床上在用的各类自锁托槽， 本发明设计更具有可操控 性， 医师不需要考虑什么时间应该如何结扎的问题， 而是只要釆取常 规的结扎， 随着矫正弓丝从细到粗的变化， 摩擦力自动实现从小到大 的转变。 既保持了临床医师传统的操作手法， 又弥补了被动自锁托槽 在矫治后期难以对牙齿进行精确控制的问题， 以及封闭盖经常会因食 物残渣镶嵌或变形而发生不能打开或打开后不能合上的缺陷，推广应 用前景极为可观。
自主低摩擦托槽在临床使用中不改变临床正畸医师传统的操作 方式， 也不需要增加其它辅助工具来进行搡作， 只要随着矫治进展， 不断更换从细到粗的矫正弓丝，即可实现从低摩擦的被动结扎到常规 摩擦的主动结扎效果。 在被动结扎状态下， 结扎丝与矫正弓丝之间没 有束缚力，可以实现牙齿快速移动，达到自锁托槽降低摩擦力的效果; 在主动结扎状态下， 结扎丝或结扎圈与主弓丝之间产生紧密束缚， 从 而可以对牙齿实现更好的转矩控制和精细调整。
相对于目前临床上常用的各类自锁托槽，本发明设计的自主低摩 擦托槽更具有可操控性， 即保持了临床医师传统的操作手法， 又弥补 了现有被动自锁托槽存在的后期治疗不能实现精确控制， 以及封闭盖 经常会因食物残渣镶嵌或变形而发生不能打开或打开后不能合上的 缺陷， 具有很好的巿场前景和极高的推广价值。
以上所述仅是本发明的优选实施方式， 应当指出， 对于本技术领 域的普通技术人员来说， 在不脱离本发明技术原理的前提下， 还可以 做出若干改进和变型， 这些改进和变型也应视为本发明的保护范围。 工业实用性
由以上实施方式可以看出，本发明实施方式提供的自主低摩擦托 槽更具有可操控性， 即保持了临床医师传统的搡作手法， 又弥补了现 有被动自锁托槽存在的后期治疗不能实现精确控制， 以及封闭盖经常 会因食物残渣镶嵌或变形而发生不能打开或打开后不能合上的缺陷， 具有很好的巿场前景和极高的推广价值。
