    • A tracker device (10,10',10") of the type associated with a surgical instrument and being trackable in space by a CAS system (100) such that a position of the surgical instrument is calculable. A support (12) is adapted to be connected to the surgical instrument. Optical elements are mounted to the support (12) in a first pattern (44A) so as to be detectable by the CAS system along a first range of visibility. Other optical elements are mounted to the support in a second pattern (44B,44C) so as to be detectable by the CAS system along a second range of visibility, with the first range of visibility and the second range of visibility having at most a common portion, whereby a position of the surgical instrument is tracked within the first and the second range of visibility as a function of the detection of any one of the patterns (44A,44B,44C) of the optical elements.
    • 一种与外科器械相关联的类型的跟踪器装置(10,10',10“),并且可通过CAS系统(100)在空间中跟踪,使得可计算外科器械的位置,支架(12) 光学元件以第一图案(44A)安装到支撑件(12)上,以便沿着可见度的第一范围可被CAS系统检测到。其他光学元件安装到支架上 第二模式(44B,44C),以便可视地识别的第二范围可由CAS系统检测,第一可见度范围和第二可见度范围至多为公共部分,由此外科器械的位置 作为对光学元件的图案(44A,44B,44C)中的任何一个的检测的函数,在第一和第二可见度范围内被跟踪。
