Description

一种金属中空螺钉
技术领域
本实用新型涉及医疗器械技术领域,具体的说是一种金属中空螺钉。 
背景技术
 股骨颈骨折是髋部最常见的损伤,在全身骨折中其发病仅次于挠骨远端骨折。这种骨折多因走路不小心跌倒,臀部着地而引起,伤后髋部疼痛,不能站立和行走。年轻人的股骨颈骨折多因车祸或高处摔伤等强烈暴力引起。股骨颈骨折的大多数有比较明显的移位,且因为这个部位的杠杆作用较大,骨折不稳定,因此,多数需要手术治疗。金属中空螺钉是固定与人体骨骼髁部的医疗器械,其股骨颈骨折的病例较为常见。现有的金属中空螺钉采用单头螺纹设计,在临床使用过程中旋合速度慢,给医生和患者带来了手术时间长的风险。 
因此,为克服上述技术的不足而设计出一种双头螺纹的金属中空螺钉产品,该产品既能够满足与骨骼形态相符、复位准确的优点,又能节约手术的时间,减少病人的痛苦,这种金属中空螺钉,正是发明人所要解决的问题。 
发明内容
针对现有技术的不足,本实用新型的目的是提供一种金属中空螺钉,其结构简单,与骨骼形态相符,复位准确,有非常好的实用价值。 
本实用新型解决其技术问题所采用的技术方案是:一种金属中空螺钉,包含钉帽、内孔、钉杆、螺纹、刃口,其特征在于:所述钉杆为圆柱形结构,钉杆一端设置有钉帽,钉杆内部为内孔,内孔另一端为刃口,刃口上设置有螺纹。 
本实用新型的有益效果是: 
1、本实用新型手术操作简便,骨折固定牢靠,创口愈合快;
2、本实用新型将传统的单头螺纹改为双头或多头螺纹,多头螺纹导程长,旋转块,大大缩短了病人手术的时间,减轻了病人的手术痛苦,有非常好的效果;
附图说明
图1是本实用新型结构示意图。 
附图标记说明:1-钉帽;2-内孔;3-钉杆;4-螺纹;5-刃口。 
具体实施方式
下面结合具体实施例,进一步阐述本实用新型,应理解,这些实施例仅用于说明本实用新型而不用于限制本实用新型的范围。此外应理解,在阅读了本实用新型讲授的内容之后,本领域技术人员可以对本实用新型作各种改动或修改,这些等价形式同样落在申请所附权利要求书所限定的范围。 
图1为本实用新型一种金属股骨颈固定空心钉结构示意图,包含钉帽1、内孔2、钉杆3、螺纹4、刃口5,所述钉杆3为圆柱形结构,钉杆3一端设置有钉帽1,钉杆3内部为内孔2,内孔2另一端为刃口5,刃口5上设置有螺纹4,本实用新型与骨骼的形态相符,复位准确,具有良好的运动稳定性,本实用新型能很好满足股骨颈的复位,尤其接近关节的部位,软组织闭合,能很好满足长骨的复位,尤其接近关节的部位。
