Description

一种可止锁的正畸器具 技术领域
本发明涉及口腔正畸器械技术领域，具体涉及一种可止锁的正畸器具。
背景技术
目前使用较多的正畸器具是托槽类的，通过在患者牙齿上粘贴具有弓丝槽的托槽和颊面管来固定弓丝，使得弓丝的数据能够表达。因为整个矫正进程中会随着疗程的进行来更换弓丝，通常是从小尺寸的弓丝逐渐过渡到大尺寸的弓丝。而托槽和颊面管上的弓丝槽的尺寸是固定的，而且弓丝槽的尺寸是大于最大尺寸的弓丝的尺寸，这就使得弓丝在弓丝槽内是能活动的，使得弓丝的转矩和数据无法准确表达。为了有效表达转矩和数据，需要设置止锁结构来将弓丝抵紧，使其无法在弓丝槽内发生移动。
本公司在先的专利申请CN110584810A中公开了一种牵引钩可移动或转动的颊面管，本发明旨在提供一种更优化的方案，可以利用牵引件来引导占位件抵紧弓丝。
发明内容

在一些优选的实施方式中，所述牵引部在活动过程中，能带动所述占位部移出所述弓丝槽内。所述牵引部还能够带动所述占位部移出所述弓丝槽，在一些优选的实施方式中，所述牵引部活动过程中一直带动所述占位部进出所述弓丝槽。
在一些优选的实施方式中，所述占位部为弹性部，使得所述占位部能抵紧不同尺寸的弓丝。
