Embodiment Construction
[0053]Embodiments of the invention are related to systems, apparatus and methods including or involving the use of optical fiber sensors, e.g., Fiber-Bragg sensors, which may be used to provide accurate shape and / or position data of an elongate instrument.
[0054]Referring to FIG. 2A, according to one embodiment, one or more components of a robotically controlled instrument 200 of a robotic surgical system include an optical fiber or fiber sensor 215 (referred to as optical fiber sensor or fiber 215), which is coupled to, or an integral part of, an elongate instrument body 210. Data based on light reflected by gratings of the fiber 215 may be used to determine the Shape and / or position of the elongate instrument, which may be a catheter, such as a guide catheter. In the illustrated embodiment, the elongate instrument or catheter 210 is a part of a robotically controlled instrument 200 that it utilized to position a bendable distal end portion 211 of the catheter 210 and one or more wo...
