近年来，导管微创手术开始流行。我们开发了一种新型力传感器，适用于实际的超细长医用线，可用于血管内弹簧圈栓塞术。传感原理基于光学测量施加压力时线材的弯曲程度。相同的传感器允许使用具有不同刚度的电线。所提出的力传感器与Y型连接器统一，这使得它与医疗设备兼容，并且可以在手术中使用。此外，该传感器不会对外科医生的熟练操作和触觉产生不良影响。本文检验了实验力传感器原型的基本特性，并通过线圈栓塞实验证实了其有效性。
Recently, minimally invasive surgery with catheter became popular. We have developed a novel force sensor for actual extra-fine and long medical wires which can be used in endovascular coil embolization. The sensory principle is based on optically measuring the wire bending when compressive force is applied. The same sensor permits use of wires with different stiffness. The proposed force sensor is unified with Y-connector, which makes it compatible with medical equipment, and can be used in surgery. Furthermore, this sensor has no bad influence on the surgeon's skillful operation and his/her haptic sense. In this paper, basic characteristics of experimental force sensor prototype are examined and its validity is confirmed by an experiment of coil embolization.
