FDA's MAUDE database holds 199 reports that name the brand "THUNDERBEAT Open Extended Jaw" (ultrasonic surgical device), received between January 2015 and July 2026; the manufacturer given most often on reports is Olympus Medical Systems. Spellings of one product vary from report to report.

12 reports arrived in the 12 months to August 2026, up 71% from 7 in the 12 months before.

The event types recorded are malfunction (89.4%), injury (9.5%) and death (1%); across all electrosurgical, cutting & coagulation & accessories reports (product code GEI) death is recorded in 0.4% and malfunction in 80.1%.

The device problems coded most often are break (68.3%), device displays incorrect message (3%) and material deformation (1.5%). The patient problems coded most often are blood loss, foreign body in patient and perforation. 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."
