Abstract

负牙侧角螺钉,它涉及医疗器械领域。它包含螺钉本体(1),它还包含负牙侧角(A)和正牙侧角(B),螺纹本体(1)的螺纹一侧为负牙侧角(A),螺纹另一侧为正牙侧角(B);所述的负牙侧角(A)为内扣式。它能有效提升螺纹的连接和紧固力。

Description

负牙侧角螺钉
技术领域:
本实用新型涉及医疗器械领域,尤其涉及一种负牙侧角螺钉。
背景技术:
医疗器械产品中所用的紧固螺钉主要是对骨折患者进行内固定,它是骨科手术中常用的骨骼固定器件。目前医用骨科螺钉的螺纹形式一般有标准螺纹和非标准螺纹之分,根据产品的设计结构决定选择不同的螺纹形式,在骨科植入物领域,用到螺纹结构形式的有脊柱椎弓根钉和与之相配的螺母及钢板螺钉,螺纹形式也有标准和非标准之分,但其基本原理和作用是紧固和连接作用,现在不管是国内或国外厂家,采用的都是这几种螺纹形式,在临床上面临的问题是螺钉的松动或紧固,现有的医用螺钉连接不牢固,容易松脱。
实用新型内容:
本实用新型的目的是提供一种负牙侧角螺钉,它能有效提升螺纹的连接和紧固力。
为了解决背景技术所存在的问题,本实用新型是采用以下技术方案:它包含螺钉本体1,它还包含负牙侧角A和正牙侧角B,螺纹本体1的螺纹一侧为负牙侧角A,螺纹另一侧为正牙侧角B。
所述的负牙侧角A为内扣式。
本实用新型的牙型采用一侧牙侧角为正,另一侧牙侧角为负,其负牙侧角部分角度是向内扣的,螺纹形式为负牙侧角的螺钉和椎弓根钉及其他的螺纹连接用于骨科内植物的固定。
本实用新型能有效提升螺纹的连接和紧固力。
附图说明:
图1为本实用新型的结构示意图。
具体实施方式:
参照图1,本具体实施方式采用以下技术方案:它包含螺钉本体1,它还包含负牙侧角A和正牙侧角B,螺纹本体1的螺纹一侧为负牙侧角A,螺纹另一侧为正牙侧角B。
所述的负牙侧角A为内扣式。
本具体实施方式的牙型采用一侧牙侧角为正,另一侧牙侧角为负,其负牙侧角部分角度是向内扣的,螺纹形式为负牙侧角的螺钉和椎弓根钉及其他的螺纹连接用于骨科内植物的固定。
本具体实施方式能有效提升螺纹的连接和紧固力。
