Abstract

本实用新型公开了一种羟基磷灰石接骨螺钉，包括：螺纹段、螺杆段和快速手柄结合段，在所述的螺纹段的外表面上设置有羟基磷灰石涂层。其优点是：接骨螺钉的螺纹段与干骨之间的生物相容性较好，促进螺钉与干骨之间紧密结合，增加固定的可靠性，降低了钉道的松动和感染率，特别适用于长期治疗患者和骨质疏松患者。

Description

羟基磷灰石接骨螺钉
技术领域
本实用新型涉及一种医疗器械，尤其涉及一种接骨螺钉。
背景技术
在外科手术中，经常会使用到接骨螺钉，使用时，接骨螺钉的螺纹段打入干骨的内部，对受伤的干骨进行固定连接。现有的接骨螺钉的结构一般包括：螺纹段、螺杆段和快速手柄结合段。接骨螺钉与干骨之间的生物相容性较差，在使用过程中，接骨螺钉的螺纹段与干骨之间不能紧密结合，钉道容易松动，钉道的感染率较高。
实用新型内容
本实用新型所要解决的技术问题是提供一种能与干骨之间紧密结合的羟基磷灰石接骨螺钉。
为了解决上述技术问题，本实用新型的技术方案是：羟基磷灰石接骨螺钉，包括：螺纹段、螺杆段和快速手柄结合段，在所述的螺纹段的外表面上设置有羟基磷灰石涂层。
本实用新型的优点是：上述羟基磷灰石接骨螺钉，接骨螺钉的螺纹段与干骨之间的生物相容性较好，促进螺钉与干骨之间紧密结合，增加固定的可靠性，降低了钉道的松动和感染率，特别适用于长期治疗患者和骨质疏松患者。
附图说明
下面结合附图对本实用新型作进一步的详细说明。
图1为本实用新型羟基磷灰石接骨螺钉的剖视结构示意图。
图2为皮质骨钉的剖视结构示意图。
图3为空心钉的剖视结构示意图。
图4为椎体钉的剖视结构示意图。
图中：1、螺纹段，2、螺杆段，3、快速手柄结合段，4、羟基磷灰石涂层。
具体实施方式
如图1所示，羟基磷灰石接骨螺钉，包括：螺纹段1、螺杆段2和快速手柄结合段3，在所述的螺纹段1的外表面上设置有羟基磷灰石涂层4。
上述接骨螺钉的螺纹段1与干骨之间的生物相容性较好，促进螺钉与干骨之间紧密结合，增加固定的可靠性，降低了钉道的松动和感染率，特别适用于长期治疗患者和骨质疏松患者。
在实际应用过程中，也可以在皮质骨钉(如图2所示)、空心钉(如图3所述)和椎体钉(如图4所示)等其它医用固定螺钉的螺纹段上设置羟基磷灰石涂层，促进上述几种螺钉与骨的结合。
