科学领域:

生物材料科学生物材料科学
手术技术手术技术
整形外科手术整形外科手术

背景情况:

现代手术程序越来越依赖于先进的材料,如超高分子量聚乙烯 (UHMWPE).
了解合属性,节点安全性和手术内条件之间的相互作用对于患者安全和手术结果至关重要.

研究的目的:

研究现代材料的生物物理结构和功能之间的关系,重点关注它们承受外科手术压力的能力.
评估不同的节点配置如何影响接材料特性和节点稳定性.
在各种结结场景中评估常见的UHMWPE和聚控制的性能.

主要方法:

四种接类型 (三种UHMWPE,一种聚) 用四种结类型 (吉隆,尼基,外科医生,Tautline) 进行了测试.
在受控的环境条件下 (20°C,65%湿度) 在干燥和潮湿状态下测量拉伸强度.
测试包括在模拟手术条件的柱子周围绑定,在定义的延展率下进行垂直拉伸测试.

主要成果:

在所有测试的 sutures 中,没有一个单一的结类型被证明是优越的.
在潮湿条件下,平均拉伸强度和低变量系数 (CV) 表示适用性.
针对EthiBond (Geelong),Orthocord (Geelong,Tautline) 和FiberWire (Nicky's,Tautline) 线,确定了特定的最佳结.
在所有节点上,ForceFiber线显示出类似的湿拉伸强度,但具有很高的变化.

结论:

接材料,结类型和环境条件之间存在显著的三向相互作用.
节点的安全性和性能可以根据特定的和手术环境而有很大差异.
这些发现对选择合适的节点具有重要意义,以确保UHMWPE接在各种手术场合的可靠性能.

Sutures of the Skull

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
