FDA's MAUDE database holds 840 reports that name the brand "Battery Oscillator" (motor surgical instrument ac-powered), received between February 2013 and October 2021; the manufacturer given most often on reports is Depuy Synthes Power Tools. Spellings of one product vary from report to report.
0 reports arrived in the 12 months to August 2026, and none in the 12 months before. FDA releases MAUDE data monthly; reports can arrive months after an event, so the newest months grow in later releases. The event types recorded are malfunction (100%); across all motor, surgical instrument, ac-powered reports (product code GEY) death is recorded in 0% and malfunction in 99.3%. Event type is the reporter's classification of the report, not a verified outcome.
The device problems coded most often are device inoperable (21.9%), mechanical jam (20.8%) and unintended system motion (17.3%). The patient problems coded most often are no patient involvement. FDA states that "MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices." It adds that the reporting system "has limitations, including the potential submission of incomplete, inaccurate, untimely, unverified, or biased data."
