A magnetic detection device is installed on the transmission link of the actuator, comprising a acquisition end and a acquisition end. A drive mechanism is activated, driving the actuator to perform linear displacement via a rotating drive component included in the transmission link.

The linear displacement stroke of the actuator is obtained based on pulse counting. In this method for measuring the displacement of the surgical instrument actuator, a magnet is mounted on a transmission gear. The characteristics of a Hall sensor are used to acquire the segment signal changes generated by the rotation of the magnet. The segment signal is converted into a linear voltage signal, then into a pulse signal.
