[0026] According to the scheme of the embodiment of the present application, the probe shaft cover 4 cooperates with the mounting base 1 to threadedly connect and movably limit the probe main body 3, and the probe main body 3 is fixedly arranged in the mounting base 1 and cannot be pulled out under the limitation of the limiting boss 31; at the same time, the limiting boss 31 cooperates with the limiting spring to move up and down or rotate the probe main body 3 to adjust the position, so as to arrange or adjust the signal of the bent and knotted optical fiber. The overall height of the optical fiber probe is shortened, and the head CT development can be cooperated in a strong magnetic environment, which is more convenient.

[0027] The following will be described in detail with specific embodiments:

[0028] The overall height of the optical fiber probe is 1.5cm-2.5cm. When the head CT development is performed in a strong magnetic environment, the distance between the development equipment and the head cannot exceed 3cm. However, the length of the existing optical fiber probe is generally 5-6cm, so the CT development operation cannot be performed while wearing the detection helmet. However, the length of the optical fiber probe of the embodiment is shortened to 3cm, so the CT development can be performed synchronously, which is more convenient and fast. Specifically, in the embodiment, the overall height of the optical fiber probe is 2.2cm.

[0029] Please refer to Figure 2 The top outer side of the mounting base 1 is provided with a threaded groove 12, and the mounting base 1 is threadedly connected with the probe shaft cover 4 through the threaded groove 12.
