The design of surgical needles used in biopsy procedures have remained fairly standard despite the increase in complexity of surgeries. Higher needle insertion forces and deflection can increase tissue damage and decrease biopsy sample integrity. To overcome these drawbacks, we present a novel bioinspired approach to reduce insertion forces and minimize needle-tip deflection. It is well known from the literature, design of bioinspired surgical needles results in decreasing insertion forces and needle-tip deflection from the needle insertion path. This technical note studies the influence of vibration on bioinspired needle to further reduce insertion forces and needle-tip deflection. Bioinspired needle geometrical parameters such as barb shapes and geometries were analyzed to determine the best design parameters. Static and dynamic (vibration) needle insertion tests were performed to determine the maximum insertion forces and to estimate needle-tip deflection. Our results show th...

振动对仿生针在组织中的插入力和偏转的影响。

尽管手术复杂性增加，但活检手术中使用的手术针的设计仍然相当标准。较高的针插入力和偏转会增加组织损伤并降低活检样本的完整性。为了克服这些缺点，我们提出了一种新颖的仿生方法来减少插入力并最大限度地减少针尖偏转。从文献中众所周知，仿生手术针的设计会降低插入力和针尖从针插入路径的偏转。本技术说明研究了振动对仿生针的影响，以进一步减少插入力和针尖偏转。分析仿生针几何参数，例如倒钩形状和几何形状，以确定最佳设计参数。进行静态和动态（振动）针插入测试以确定最大插入力并估计针尖偏转。我们的结果表明...
