概括

阿塔拉螺丝提供了与侧面质量螺丝相似的安全性,并且在后椎固定中比它们更强. 然而,脚螺丝显示出优越的生物力学固定,特别是在C5-C6范围内.

科学领域:

整形外科手术整形外科手术
生物机械工程生物机械工程
脊柱融合技术脊柱融合技术

背景情况:

亚轴椎脊柱 (SCS) 的后部固定传统上使用侧面质量螺丝 (LMS),以脚螺丝作为替代方案.
新型的阿塔拉螺丝旨在将LMS的安全性与脚螺丝的强度相结合.

研究的目的:

为了比较分析亚轴椎 (SCS) 中的阿塔拉螺丝,脚螺丝和侧面质量螺丝 (LMS) 的峰值插入扭矩.

主要方法:

用电子扭矩螺丝刀在尸体SCS中测量了阿塔拉螺丝 (n=15),脚螺丝 (n=8) 和LMS (n=7) 的最大插入扭矩.
使用标准的外科手术技术和仪器插入螺丝.

主要成果:

脚螺丝和阿塔拉螺丝在C3,C4和C7.7处显示了类似的插入扭矩.
脚螺丝在C5和C6时表现出明显高于阿塔拉螺丝的扭矩.
与LMS相比,从C4到C7的脚螺丝显示出更高的扭矩.
阿塔拉螺丝显示出比LMS更高的扭矩,主要是在C7.

结论:

与LMS相比,阿塔拉螺丝在后宫固定方面表现出高度依赖的优越稳固性.
脚螺丝仍然是生物机械上优越的选择,用于固定C5-C6下轴椎.

Self-Locking Screw

Self-Locking Screw

A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.

Screw: Problem Solving

Screw: Problem Solving

In mechanical engineering, the interaction between a threaded screw shaft and a plate gear involves analyzing the resisting torque on the plate gear that can be overpowered when a specific torsional moment is applied to the shaft. To better comprehend this concept, consider a generic situation with a threaded screw shaft with a given mean radius and lead and a plate gear with a specified mean radius. The coefficient of static friction between the screw and gear is also provided.
To evaluate the...
