[0036] The working principle of the present utility model is as follows: the above embodiment discloses a handheld nerve probe for peripheral nerve balance surgery, wherein the top of the detection head 3 is plugged into the bottom of the detector body 1, and then the first protective shell 2 is sleeved on the lower part of the detector body 1, and then the first protective shell 2 squeezes the first clamping column 6, so that the first clamping column 6 squeezes the first spring 5, thereby compressing it, and then when the first clamping column 6 reaches the second limiting groove 7, the first spring 5 rebounds, limiting the first protective shell 2 to prevent it from loosening, and then by squeezing the second clamping column 10, it compresses the second spring 9, so that the detection head 3 can be in the first protective shell. 2 slides inside, but the second clamping column 10 moves to the fourth limiting groove 11, and the second clamping column 10 limits and fixes the detection head 3. Through the second clamping columns 10 of different heights, different length adjustments are achieved. Finally, the second protective shell 12 is put on the bottom of the detection head 3, and then external force is applied to the second protective shell 12 to move it upward.

According to the numerical feedback of electrical stimulation, the first bundle is the sensory bundle and the second bundle is the motor bundle. The median nerve is divided into five bundles. According to the numerical feedback, the first and second bundles are the sensory bundles, and the third and fourth bundles are the motor bundles. The ulnar nerve is divided into five bundles. According to the numerical feedback, the first bundle is the motor bundle, and the second, third, and fourth bundles are the sensory bundles. The radial nerve is divided into six bundles. According to the numerical feedback, the first and fifth bundles are the sensory bundles, and the second, fourth, and sixth bundles are the motor bundles.
