A nerve detection device, comprising a needle (7), a handle (4), and an elastic force prompt member (10). The needle (7) is connected to the handle (4), and comprises a probe (1), an elastic member (8), and an elastic force measurement member (11). The probe (1) is connected to the elastic member (8). The elastic force measurement member (11) is connected to the elastic member (8), and is used for measuring an elastic force value of the elastic member (8), and transforming the measured elastic force value into an electric signal. The elastic force prompt member (10) is electrically connected to the elastic force measurement member (11), and is used for receiving an electric signal and generating prompt information on the elastic force value according to the electric signal. |
