Abstract
The present disclosure provides a surgical instrument control circuit. The control circuit includes a primary processor, a safety processor in signal communication with the primary processor, and a segmented circuit comprising a plurality of circuit segments in signal communication with the primary processor. The plurality of circuit segments comprising a storage verification segment configured to indicate when a surgical instrument has been properly stored and sterilized.
Claims7
A surgical instrument control circuit, comprising:
- a primary processor;
- a safety processor in signal communication with the primary processor;
- and
- a segmented circuit located within a surgical instrument, the segmented circuit comprising a plurality of circuit segments in signal communication with the primary processor, the plurality of circuit segments comprising a storage and sterilization verification segment configured to determine that the surgical instrument has been properly stored and sterilized,
- wherein the safety processor is configured to prevent operation of at least one of the plurality of circuit segments after the storage and sterilization verification segment determines that the surgical instrument has been improperly sterilized,
- wherein the storage and sterilization verification segment comprises at least one sensor configured to detect one or more improper storage or sterilization parameters,
- wherein the at least one sensor comprises a drop protection sensor, and the safety processor is configured to prevent operation of at least one of the plurality of circuit segments when the drop protection sensor detects that the surgical instrument has been dropped,
- wherein the segmented circuit comprises an accelerometer, and at least one of the primary processor or the safety processor is configured to monitor the accelerometer and to transition the segmented circuit to a sleep mode when no movement of the accelerometer is detected within a predetermined time period.
