Abstract

Catheter is one of the medical tools for endovascular surgeries, and it is frequently used for neurosurgical operations. There is, however, a problem that doctors operate a catheter without any force information during their operation, and this problem causes fatigue of doctors. To solve this problem, we propose a micro force sensor for intravascular neurosurgery. This micro force sensor can be installed on the tip of the catheter. The diameter of this sensor is 1.5 mm and length is 12 mm. Using this micro force sensor, we can measure the contact force between the catheter and blood vessels. To express the contact force between catheter and blood vessels is very effective for safe operation. In this paper, we show the structure of the micro force sensor and its characteristics, and also we present the result of an in vivo experiment.

血管内神经外科微力传感器及体内实验

导管是血管内手术的医疗工具之一，常用于神经外科手术。但是，在手术过程中，医生在没有任何力量信息的情况下操作导管，这是一个问题，这导致了医生的疲劳。为了解决这个问题，我们提出了一种用于血管内神经外科的微型力传感器。这种微型力传感器可以安装在导管的尖端。该传感器直径为1.5 mm，长度为12mm。利用这种微型力传感器，我们可以测量导管与血管之间的接触力。表达导管与血管之间的接触力对安全操作是非常有效的。本文介绍了微力传感器的结构和特点，并给出了在体实验的结果。
