用于夹持光学形状感测纤维的夹持机构
摘要：
一种用于固定光纤(OSF)的夹持机构，该光纤(OSF)具有光学形状感测特性且被布置成用于光学形状感测。优选具有圆形横截面的固定元件用于与附加固定装置一起接合所述光纤(OSF)，该附加固定装置具有被布置成用于接合所述相关光纤(OSF)的直的纵向部分，所述光纤(OSF)的一区段的固定使所述光纤(OSF)处于直的状态。在一些实施例中，夹持机构可以通过具有圆形横截面的三个直杆(R1,R2,R3)来实现，例如，具有相同直径，该直径是所述光纤(OSF)的直径的倍数，如6.46倍。因此，利用所述夹持机构可以实现所述光纤(OSF)的有效固定和校直，且不会干扰应变，所述夹持机构在实际使用时易于组装和拆解，例如，在用作发射固定装置且所述光纤(OSF)被结合到医用装置中时。
摘要（英）：

A clamp mechanism for fixation of an optical fiber (OSF) with optical shape sensing properties arranged for Optical Shape Sensing. A fixing element preferably with a circular cross section serves to engage with the optical fiber (OSF), and together with an additional fixing arrangement with a straight longitudinal portion arranged for engaging with the associated optical fiber (OSF), a fixation of a section of the optical fiber (OSF) is provided with the optical fiber (OSF) in a straight position. In some embodiments, the clamp mechanism can be implemented by three straight rods (R1, R2, R3) with circular cross section, e.g. with the same diameter being a factor of such as 6.46 times a diameter of the optical fiber (OSF). Hereby an effective fixation and straightening of the optical fiber (OSF) without disturbing strain can be obtained with a clamp mechanism which is easy to assemble and disassemble in practical applications e.g. when used as a launch fixture, and with the optical fiber (OSF) incorporated in a medical device.
