Surgical instrument power management through sleep and wake up control

A surgical instrument comprising:

• a motion sensor configured to sense movement of the surgical instrument;
• and
• a control circuit coupled to the motion sensor, the control circuit configured to:
• monitor the motion sensor to sense movement of the surgical instrument;
• transition the surgical instrument to a sleep mode when the surgical instrument has been stationary for a period above a predetermined threshold;
• and
• transition the surgical instrument to an operational mode when the surgical instrument has been moved;
• wherein in the sleep mode the control circuit is configured to place a component of the surgical instrument in a low-power state;
• wherein in the operational mode the control circuit is configured to activate the component of the surgical instrument.

A surgical instrument comprising:

• a motion sensor configured to sense movement of the surgical instrument;
• a sensor configured to detect user interaction with the surgical instrument;
• and
• a control circuit coupled to the motion sensor and the sensor, the control circuit configured to:
• monitor the motion sensor to sense movement of the surgical instrument;
• determine whether the surgical instrument has been stationary for a period;
• transition the surgical instrument to a sleep mode when the period is above a threshold period;
• monitor the sensor to sense user interaction with the surgical instrument;
• and
• transition the surgical instrument to an operational mode when a user has interacted with the surgical instrument;
• wherein in the sleep mode the control circuit is configured to place a component of the surgical instrument in a low-power state;
• wherein in the operational mode the control circuit is configured to activate the component of the surgical instrument.
