Measuring and controlling the force required to grip a nerve is required to avoid any undesired neurological damage caused by an excessive suction force applied to the tissue. We aimed to develop a suction-based nerve gripper that can measure the suction force applied to the gripped peripheral nerve. A tiny force sensor can be incorporated by casting a soft material on a barometric pressure sensor chip and embedding it in the suction tip. In this study, a suction tip was designed based on a parametric analysis. The sensing characteristics and performance were evaluated experimentally. The experimental results demonstrate that a suction tip exhibits a force measurement capacity of approximately 2.8 N with a controlled suction force at 0.1 N intervals. The practical applicability of the proposed gripper was assessed based on an in vivo experiment performed on small animal subjects.

一种基于吸力的可控制吸力的周围神经夹持器


需要测量和控制夹紧神经所需的力，以避免因施加到组织上的吸力过大而造成任何不良的神经损伤。我们的目标是开发一种基于吸力的神经夹持器，可以测量施加到所夹持的周围神经的吸力。通过在气压传感器芯片上浇注软材料并将其嵌入吸头中，可以集成微型力传感器。在本研究中，基于参数分析设计了吸嘴。通过实验评估传感特性和性能。实验结果表明，吸头表现出约 2.8 N 的力测量能力，并且以 0.1 N 的间隔控制吸力。基于对小动物受试者进行的体内实验评估了所提出的夹具的实际适用性。
