摘要:
The present invention relates to a kind of elongated intervention devices (1), it is configured to reception optic shape sensing optical fiber (9) and includes: (i) elongated proximal section (22), it includes the fixing element (24) in its proximal end, which can be connected to the receiving element (25) at predetermined position (3) And (ii) is connected to the elongated distal section (21) of proximal section (22). Proximal section (22) has compared to lower torsion stiffness for distal section (21) and including at least two substantially coaxial pipes (31,32), and outer tube (31) has compared to lower torsion stiffness for inner tube (32). Therefore, the elongated intervention device (1) can be fixed to predetermined position and determine its shape and position will pass through optic shape sensing, and the operability without will affect the device, especially for the rotary motion of distal section (21).
