1. A use instrument predicting device, comprising:
a motion sensor that detects a motion of a surgeon during a surgical operation;
calculation circuitry that includes:
a first learned model to derive a motion of a surgeon during a surgical operation based on the detected motion, the first learned model learned with first teaching data in which the detected motion is associated with the surgeon's motion,
a second learned model to derive a surgery situation, the second learned model learned with second teaching data including the surgeon's motion derived from the first learned model, contents of the surgical operation and lapsed time of the surgical operation,
a third learned model to predict at least one kind of surgical instrument to be used next by the surgeon out of a plurality of kinds of surgical instruments given beforehand, the third learned model learned with third teaching data including the surgery situation derived from the second learned model and surgeon identification information,
wherein the third learned model also derives a handing position according to the predicted at least one kind of surgical instrument, the handing position being defined according to contents of the surgical operation, a position defined beforehand according to a progress state of the surgical operation, or the surgeon's favorite handing position, the handing position being a position where the predicted at least one kind of surgical instrument is passed to the surgeon; and
output circuitry configured to output the output data.
