Description

一种正畸自锁托槽 技术领域
本发明涉及牙齿矫正工具，更具体地说，它涉及一种正畸自锁托槽。
背景技术
正畸治疗是牙科领域的一门专业化程度较高的分支学科，主要是针对牙齿、颌骨、面部畸形进行矫治，通过在口腔内部安装固定正畸矫治器来逐渐恢复患者的正常咬合功能。托槽是固定矫治技术的重要部件，用粘接剂直接粘接于牙冠表面。正畸治疗通过将矫治弓丝安装在托槽的槽沟内，弓丝通过托槽对牙施以各种类型的矫治力，引导错位的牙齿移动到理想的位置。其中，托槽主要作用在于固定弓丝，从而使弓丝更好的发挥作用，传递矫治力，以此控制牙齿三维的移动，达到正畸矫治的目的。
普通托槽需要医生在每次复诊换弓丝时，重新结扎，会花费大量时间，同时由于弓丝与托槽体结扎在一起，使得弓丝与托槽之间的摩擦力大，导致矫治力增加，需要更大的支抗，同时也减慢了牙齿的移动速度。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种正畸自锁托槽，提高了牙齿的移动速度，缩短了整个治疗周期。
本发明的上述技术目的是通过以下技术方案得以实现的：一种正畸自锁托槽，包括托槽底板，以及设置在托槽底板上的托槽体，托槽体中部向下凹陷形成弓丝槽，弓丝槽上方设有与托槽体滑移配合的锁片，锁片下表面设有锁止槽，锁止槽一端设有第一锁止位，锁止槽另一端设有第二锁止位，第一锁止位和第二锁止位之间通过过渡位过渡连接，托槽体上设有将锁片固定于第一锁止位和第二锁止位的锁止机构，锁止机构包括位于托槽体上的弹性件，弹性件上设有可被该锁止位接收的凸起，当弹性件上的凸起被第一锁止位接收时，锁片处于锁止状态；当弹性件上的凸起被过渡位接收时，锁片处于半开状态，并迫使弹性件收缩并蓄能；当弹性件上的凸起被第二锁止位接收时，锁片处于打开状态。
通过采用上述技术方案，使用自锁托槽可以节省每次复诊换弓丝的时间，同时，弓丝在弓丝槽内自由滑动，摩擦力小，矫治力小，病人无明显疼痛感，提高牙齿的移动速度，缩短了整个治疗周期，锁片滑动锁定，其操作方便，被广泛的用于牙科正畸，锁片与托槽体之间设置锁止机构，锁止机构相当于托槽体上加了一道门，一方面可以直接将正畸弓丝锁闭在托槽体的弓丝槽内，免除了结扎钢丝对正畸钢丝的捆绑，另一方面有效防止滑动时锁片的脱落，使锁片能够牢固的锁紧托槽体，锁止机构结构设计合理，在滑移过程中操作顺畅，当锁 片处于半开状态，迫使弹性件收缩并蓄能，方便将锁片切换至打开或者闭合状态，操作省力。
本发明进一步设置为：所述托槽体上设有供锁片滑移的滑槽，滑槽两侧设有槽轨，锁片两侧设有与槽轨滑移配合的滑条。
通过采用上述技术方案，锁片上的滑条与滑槽上的槽轨默契配合，对锁片起到导向和定位作用，锁片限定在槽轨内滑动，使锁片不产生左右为宜，稳固的锁定在滑槽上。
本发明进一步设置为：本发明进一步设置为：所述凸起为滚珠，所述弹性件为塔簧。
通过采用上述技术方案，凸起采用滚珠，操作方便，省事省力，弹性件采用塔簧，体积小，载荷大，广泛应用于狭小空间内，具有很好的减震效果。
本发明进一步设置为：所述托槽体中心处开有滚珠定位孔，滚珠定位孔内设有塔簧，塔簧上压有滚珠。
通过采用上述技术方案，滚珠定位孔的设置方便滚珠和塔簧的固定和定位，结构简单。
本发明进一步设置为：所述托槽底板正面中心处开有上沟槽，上沟槽内设有用于定位塔簧的凸起。
通过采用上述技术方案，上沟槽的设计，与托槽体上滚珠定位孔配合，共同作用锁止机构，弹性件采用塔簧，塔簧限位在上沟槽内的凸起上，弹性件不易移位。
本发明进一步设置为：所述托槽体带有不对称结扎翼，结扎翼内分别设计有允许锁片插入的卡槽。
通过采用上述技术方案，卡槽的设置方便锁片的定位，便于锁片滑移过程对端部的定位作用。
本发明进一步设置为：所述结扎翼一侧增厚设置，另一侧减薄设置，且结扎翼自由端内扣并呈一定弧度设置。
通过采用上述技术方案，节省了空间，避免操作时误伤口腔，使用安全，且使托槽体整体更美观。
本发明进一步设置为：所述托槽底板底部设有沾合网，沾合网的外围设有防止胶体向沾合网外部扩散的围壁。
通过采用上述技术方案，当胶体涂在沾合网上与牙齿抵触贴合时，由于沾合网的外围设置有围壁，所以当胶体扩散到围壁处时，围壁就有效的起到了对胶体的阻挡作用，即防止了胶体继续向沾合网的外部四处扩散情况；同时当胶体流动到围壁处时，由于围壁对胶体的阻挡而产生的反作用力，会使得胶体又会回流到沾合网上未充满胶体的沟槽中，进一步的使得胶体能够均匀的涂抹在沾合网上，从而与牙齿起到有效的沾合作用。
本发明进一步设置为：所述围壁中间形成供胶体流动的沟槽，围壁背向底板的一侧设 置贴合壁，贴合壁与牙齿贴合并呈弧形设置。
通过采用上述技术方案，采用人体工学设计，贴合壁呈弧形设置，使贴合壁与牙齿贴合度更好，佩戴更舒服。
本发明进一步设置为：所述凸起设置为长条形，长条形朝向第二锁止位一侧设置为半球形，所述凸起与托槽体朝向弓丝槽一侧呈锐角设置，所述托槽体上开设有仅供凸起上下位移的滑移槽，所述凸起相对半球形一端开设有与滑移槽内壁平行且与滑移槽相对弓丝槽一侧内壁抵接的直面一。
通过采用上述技术方案，通过将凸起与托槽体呈锐角设置、且凸起一端与滑移槽相对弓丝槽一侧内壁直面抵接，使其滑移槽给予凸起朝向弓丝槽一侧的支撑力，弹性件给予凸起朝上支撑力，增强对锁片的限位作用，使其自锁托槽将弓丝固定在口腔内，在咀嚼食物时，锁片不易滑落，保证自锁托槽以及弓丝的稳定性。
综上所述，本发明具有以下有益效果：
其一，使用自锁托槽可以节省每次复诊换弓丝的时间，同时，弓丝在弓丝槽内自由滑动，摩擦力小，矫治力小，病人无明显疼痛感，提高牙齿的移动速度，缩短了整个治疗周期，锁片滑动锁定，其操作方便，被广泛的用于牙科正畸，锁片与托槽体之间设置锁止机构，有效防止滑动时锁片的脱落，就要求滑动锁盖必须能够牢固的锁紧托槽体，滑动锁片与托槽体之间紧密配合，在滑移过程中操作顺畅。锁止机构结构设计合理，当锁片处于半开状态，迫使弹性件收缩并蓄能，方便将锁片切换至打开或者闭合状态；
其二，锁片上的滑条与滑槽上的槽轨默契配合，对锁片起到导向和定位作用，锁片限定在槽轨内滑动，使锁片不产生左右为宜，稳固的锁定在滑槽上；

沾合网15的外围设有防止胶体向沾合网15外部四处扩散的围壁16，在围壁16中间形成供胶体流动的下沟槽17，围壁16背向底板的一侧设置贴合壁18，贴合壁18与牙齿贴合并呈弧形设置。
实施例2，如图9所示，与实施例一不同之处在于，上述凸起8采用圆柱，圆柱位于第二锁止位52一端设置为半球形，弹性件7与圆柱另一端连接，托槽体2上开设有供圆柱仅能上下位移的滑移槽22，滑移槽22宽度与圆柱直径相等，圆柱与托槽体2朝向弓丝槽3一侧呈锐角设置，圆柱相对半球形一端开设有与滑移槽22内壁平行且与滑移槽22相对弓丝槽3一侧内壁抵接的直面一23、以及与直面一23垂直的直面二24，直面二24与弹性件7端面抵接。
本实施例中，圆柱与托槽体2之间夹角为45°。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
