[0026] For examples, please refer to Figure 1-4 This utility model provides a technical solution:

[0027] A two-segment neurophysiological signal monitoring probe includes a probe tip 1 and a rear connector 2 disposed behind the probe tip 1. A front connector 3 is connected to the rear end of the probe tip 1. A connection mechanism 4 is provided between the front connector 3 and the rear connector 2. A signal processor 5 is disposed on the rear side of the rear connector 2. A control switch 501 is disposed on the top of the signal processor 5. A signal transmission interface 502 is installed on the rear side of the signal processor 5.

[0028] It should be noted that the rear connector 2 is electrically connected to the front connector 3 via a male-to-female plug, and the signal processor 5 is fixedly connected to the rear surface of the rear connector 2 via a fixing post. The signal processor 5 is electrically connected to the rear connector 2 and the control switch 501 via wires.

[0029] Specifically, the outer surfaces of both the rear connector 2 and the front connector 3 are made of polytetrafluoroethylene (PTFE).

[0030] In this embodiment, the insulation performance of the rear connector 2 and the front connector 3 is improved by using polytetrafluoroethylene material.

[0031] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The connecting mechanism 4 includes a mounting ring 401 and a fastening socket 402. The mounting ring 401 is fixedly mounted on the outer surface of the rear connector 2. A fastening post 403 is fixedly provided on the outer surface of the mounting ring 401. A cavity 404 is opened inside the fastening post 403. A fastening rod 405 is respectively provided inside the cavity 404. A fastening spring 406 and a limiting block 407 are respectively sleeved on the outer side of the fastening rod 405. The fastening socket 402 is opened at the left and right ends of the front connector 3.

[0032] Specifically, the inner wall of the mounting ring 401 is in contact with the outer surface of the front connector 3, the fastening posts 403 are located at the left and right ends of the mounting ring 401, the inner wall of the limiting block 407 is fixed to the outer surface of the fastening rod 405, the outer surface of the limiting block 407 is in contact with the inner wall of the cavity 404, the inner wall of the fastening spring 406 is slidably connected to the outer surface of the fastening rod 405, one end of the fastening rod 405 extends movably to the left side of the fastening post 403, and the other end of the fastening rod 405 extends movably to the inner side of the mounting ring 401 and is in stable contact with the inner wall of the fastening hole 402.

[0033] In this embodiment, the mounting ring 401 is mainly used to contact the outer surface of the front connector 3, so that the rear connector 2 can be close to the front connector 3.

[0034] The working process of this utility model is as follows: When using a two-segment neurophysiological signal monitoring probe, the probe tip 1 is first moved to contact the patient's nerve tissue. Then, the monitoring device is connected to the signal transmission interface 502 through the interface module. Subsequently, the rear connector 2 and the front connector 3 can be connected. As the rear connector 2 moves, the mounting ring 401 gradually moves along the surface of the front connector 3 until the rear connector 2 and the front connector 3 are electrically connected through a male-to-female plug. At this time, under the extension of the fastening spring 406, the fastening spring 406 applies a force to the limiting block 407, and the limiting block 407 drives the fastening rod 405 to move towards each other and gradually come into contact with the fastening socket 402, ensuring a stable connection between the front connector 3 and the rear connector 2. This effectively prevents the connection from loosening and ensures the stability and reliability of signal transmission.
