Abstract

本发明公开了一种接骨板万向锁定加压装置，是在接骨板本体上设有长形滑孔，长形滑孔内安装有锁紧滑块，锁紧滑块上设有锥形螺钉孔，锥形螺钉孔内装有锥头螺钉，长形滑孔横截面的两内侧轮廓线形状为弧形，锁紧滑块的两侧面形状为与其相适应的弧面，锁紧滑块的中部带有凹形缺口。锁紧滑块不仅可以在长形滑孔内滑动，加压效果好，而且可以左右摆动，使螺钉按临床需要调整方向，减小操作难度，由于锁紧滑块两侧面为弧面，在旋紧螺钉后可完全避免锁紧滑块的脱出，提高了手术质量。

Description

接骨板万向锁定加压装置
技术领域
本发明涉及一种接骨板，具体地说是涉及一种接骨板的锁定加压装置。
背景技术
接骨板是目前治疗骨折最常用的内固定器材。传统的金属接骨板是在接骨板本体上设有螺钉固定孔，通过带有锥形外螺纹的螺钉固定。为提高治疗效果，加快骨折断端愈合，近年来出现了诸如专利号为200520009461.1的加压接骨板，它们都是通过螺钉和螺钉孔的斜面实现加压，调节距离短，加压效果差，并且螺钉方向不可调节，致使操作麻烦，影响手术质量。由本申请人发明的专利号为201020014496.5的万向锁定金属接骨板虽然可以调节螺钉方向，但无加压效果。
发明内容
本发明的目的就是针对上述现有技术的不足，提供一种既可以方便调节螺钉方向，又可以任意调节加压距离的接骨板锁定加压装置，以减小手术操作难度，提高治疗效果。
本发明是对现有接骨板的改进，它是在接骨板本体上设有长形滑孔，长形滑孔内安装有锁紧滑块，锁紧滑块上设有锥形螺钉孔，锥形螺钉孔内装有锥头螺钉。长形滑孔的两侧面为内弧面，即长形滑孔横截面的两内侧轮廓线形状为弧形，锁紧滑块的两侧面形状为与其相适应的外弧面，锁紧滑块的中部带有凹形缺口，该凹形缺口将锁紧滑块分成对称的两瓣，但两瓣的底面相连接。
本发明的锁紧滑块可以在长形滑孔内滑动，任意调节加压距离，因而加压效果好；由于长形滑孔的两侧面为弧面，锁紧滑块的两侧面同样为与其相适应的弧面，从而在旋紧螺钉后可完全避免了锁紧滑块的脱出，并且在操作时锁紧滑块可以左右摆动，使螺钉按临床需要调整方向，减小了操作难度，提高了手术质量。
附图说明
图1为本发明的主视图；
图2为图1中的A-A剖视放大图；
图3为锁紧滑块的主视图；
图4为图3的左视图；
图5为图3中的B-B剖视图。
具体实施方式
附图所示实施例，本发明是在接骨板本体1上设有长形滑孔2，长形滑孔2内安装有锁紧滑块3，锁紧滑块3上设有锥形螺钉孔3-3，锥形螺钉孔3-3内装有锥头螺钉4。长形滑孔2横截面的两内侧轮廓线形状为弧形，也就是说，长形滑孔2的两纵向表面为内弧面，锁紧滑块3的两侧面形状为与其相适应的外弧面3-1。锁紧滑块3的中部带有凹形缺口3-2，该凹形缺口3-2将锁紧滑块3分成对称的两瓣，但其底面还稍有连接，这样在安装时，向内压缩两瓣即可方便地将锁紧滑块3卡进长形滑孔2内。操作时，可以在长形滑孔2内滑动锁紧滑块3以适应加压需要，并且可以左右摆动锁紧滑块3以使锥头螺钉4按临床需要调整方向，待调节合适后，拧紧锥头螺钉4，锥头螺钉4的锥头将锁紧滑块3的两瓣向外撑开，压紧在长形滑孔2内壁以实现锁定。由于二者为弧面接触，因而不会脱出。
