Abstract

本发明公开了一种伸肌腱止点固定器，包括：固定杆和螺钉，所述固定杆呈门字形，固定杆两端设有固定环，固定环上开有螺钉孔，螺钉孔为偏心孔；所述螺钉有两个，两个螺钉分别设置在固定环的螺钉孔内。通过上述方式，本发明能够实现肌腱止点线状重建。

Description

伸肌腱止点固定器
技术领域
本发明涉及伸肌腱止点重建内固定材料领域，特别是涉及一种伸肌腱止点固定器。
背景技术
手外伤手指伸肌腱止点撕脱，手术予肌腱止点重建常采用钢丝捆扎、铆钉重建止点。钢丝捆扎手术简单，治疗费用低，但是术后针道护理麻烦，容易引起感染，需二次手术取出内固定，术后患者生活不便，患者不容易接受。近年随着内固定物的发展，用铆钉予肌腱止点重建也经常采用，术后患者不需针道护理，对生活影响小，不需予内固定取出，但术后发现部分病例铆钉有松动，皮下线结反应大。总结引起以上问题的原因有：1）铆钉属点状止点重建，而肌腱止点为线状；2）铆钉固定方向与肌腱力线方向相似；3）止点线结较多、缝线较粗；4）伸肌腱止点背侧皮肤较薄。
发明内容
本发明主要解决的技术问题是提供一种伸肌腱止点固定器，固定器可不予取出，伸肌腱固定器符合肌腱止点线状重建，减少缝线预防线结反应，螺钉固定方向与肌腱力线垂直，术后不易松动，螺钉位置靠两侧，避免顶压伸肌腱止点背侧皮肤。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种伸肌腱止点固定器，包括：固定杆和螺钉，所述固定杆呈门字形，固定杆两端设有固定环，固定环上开有螺钉孔，螺钉孔为偏心孔；所述螺钉有两个，两个螺钉分别设置在固定环的螺钉孔内。
优选的，所述固定杆包括横杆和固定在横杆两端的竖杆，竖杆与横杆之间倾斜设置。
优选的，所述螺钉为松质骨螺钉。
本发明的有益效果是：本发明伸肌腱固定器符合肌腱止点线状重建，减少缝线预防线结反应，螺钉固定方向与肌腱力线垂直，术后不易松动。
附图说明
图1是本发明伸肌腱止点固定器一较佳实施例的立体结构示意图；
图2是所示伸肌腱止点固定器的使用状态结构示意图。
附图中各部件的标记如下：1、固定杆；2、固定环；3、螺钉。
具体实施方式
下面结合附图对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
请参阅图1和图2，本发明实施例包括：
一种伸肌腱止点固定器，包括：固定杆1和螺钉3，所述固定杆1呈门字形，固定杆1包括横杆和固定在横杆两端的竖杆，竖杆与横杆之间倾斜设置，竖杆两端设有固定环2，固定环2上开有螺钉孔，螺钉孔为偏心孔，拧紧螺钉时固定杆有加压作用；所述螺钉3有两个，螺钉为松质骨螺钉，两个松质骨螺钉分别设置在固定环2的螺钉孔内。可根据指体大小设计不同型号固定杆及螺钉，固定杆压住伸肌腱于止点，两端螺钉拧紧实现固定作用。
伸肌腱止点断裂，肌腱断端无明显缺损，切开皮肤暴露肌腱止点断端，咬除肌腱止点少许骨质。近指间关节屈曲位、远指间关节伸直位时复位伸肌腱止点，然后选择合适大小的固定器，固定杆压住伸肌腱止点，两端螺钉拧紧固定伸肌腱止点，缝合皮肤；术后配合支具制动，近指间关节屈曲位、远指间关节伸直位；术后6周去除外固定开始功能锻炼。固定器可不予取出，伸肌腱固定器符合肌腱止点线状重建，减少缝线预防线结反应，螺钉固定方向与肌腱力线垂直，术后不易松动，螺钉位置靠两侧，避免顶压伸肌腱止点背侧皮肤。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
