The surgical instrument (100) is provided with a gear (101) that is rotatably configured and a gear-moving mechanism (103) that rotates the gear (101). On the gear (101), a potentiometer 102 is provided. To an arm portion (200), a columnar portion (201) that moves the gear (101) by a predetermined amount via the gear-moving mechanism (103) when the surgical instrument (100) is mounted is provided. When the surgical instrument (100) is mounted on the arm portion (200), the gear (101) is caused to rotate via the gear-moving mechanism (103). As a result, an output voltage value of the potentiometer (102) is changed, and the usage count of the surgical instrument (100) is accumulated. |
