Description

一种带尾孔空心加压螺钉
技术领域
本发明涉及一种空心加压螺钉的改进，特别是一种结构简单，能够对韧带肌腱止点修复，提高术后韧带强度的带尾孔空心加压螺钉。
背景技术
现在通用的空心加压螺钉，包括钉帽、钉体、钉尖，沿其轴心线开有通孔，其针尖是自攻针尖。骨折复位后用克氏针固定、沿克氏针用空心加压螺钉固定。螺钉对骨折有加压作用，常常用于肌腱韧带止点部位撕脱骨折，骨折复位内固定时常常需要对软组织进行剥离，骨折复位内固定术后，对韧带肌腱止点常常无法修复，或者与残存组织缝合，术后韧带强度明显下降。
发明内容
本发明主要解决的技术问题是提供一种结构简单，能够对韧带肌腱止点修复，提高术后韧带强度的带尾孔空心加压螺钉。
为解决上述技术问题，本发明采用的一个技术方案是：一种带尾孔空心加压螺钉，包括：螺钉本体，所述螺钉本体从上到下依次包括：钉帽、钉体和钉尖；所述螺钉本体上沿轴心线设有通孔；所述螺钉本体上端设有孔槽；所述孔槽下端与通孔相通；所述钉体下部外壁以及钉尖外壁设置有螺纹；所述钉尖外壁的螺纹上设有自攻槽；所述钉帽的外壁上设有穿线孔，所述穿线孔中部穿过孔槽；所述穿线孔的进口和出口均在钉帽外壁上；所述穿线孔的进口和出口的上端均竖直设置有线槽；所述线槽上端与钉帽上端面连通，下端与穿线孔连通。
优选的，所述孔槽呈内六角型。
本发明的有益效果是：本发明所述的一种带尾孔空心加压螺钉；结构简单，能够对韧带肌腱止点修复，提高术后韧带强度。
附图说明
附图1为本发明的一种三孔带线锚钉的结构示意图；
附图2为本发明的一种三孔带线锚钉的主视图；
附图3为图2的A-A的结构剖视图；
附图4是图1的俯视图；
其中：1、螺钉本体；2、钉帽；3、钉体；4、钉尖；5、通孔；6、孔槽；7、螺纹；8、自攻槽；9、穿线孔；10、线槽。
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至图4，本发明实施例包括：
一种带尾孔空心加压螺钉，包括：螺钉本体1，所述螺钉本体1从上到下依次包括：钉帽2、钉体3和钉尖4；所述螺钉本体1上沿轴心线设有通孔5；所述螺钉本体1上端设有孔槽6；所述孔槽6呈内六角型；所述孔槽6下端与通孔5相通；所述钉体3下部外壁以及钉尖外壁设置有螺纹7；所述钉尖4外壁的螺纹7上设有自攻槽8；所述自攻槽8可以有效的分散应力，防止骨屑下落；所述钉帽2的外壁上设有穿线孔9，所述穿线孔9中部穿过孔槽6；所述穿线孔9的进口和出口均在钉帽2外壁上；所述穿线孔9的进口和出口的上端均竖直设置有线槽10；所述线槽10上端与钉帽2上端面连通，下端与穿线孔9连通。
手术时，将螺钉本体1固定在骨头上，将缝线从穿线孔9的进口穿入，经过孔槽6后，再从穿线孔9的出口穿出；同时，将缝线的两端分别嵌入与穿线孔6的进口和穿线孔6的出口相连通的线槽10中，再将缝线的两端穿过肌腱韧带，并且在肌腱韧带的上端进行打结；用于缝合固定肌腱韧带，重建肌腱韧带止点。
本发明的有益效果是：本发明所述的一种带尾孔空心加压螺钉；结构简单，能够对韧带肌腱止点修复，提高术后韧带强度。
以上仅是本发明的具体应用范例，对本发明的保护范围不构成任何限制。凡采用等同变换或者等效替换而形成的技术方案，均落在本发明权利保护范围之内。
