Questions about single-use reprocessed ultrasonic surgical instruments reports

What is product code NLQ?

FDA's classification code for "Single-use reprocessed ultrasonic surgical instruments", class U, reviewed by the unknown panel. Every device report carries the product code of the device involved.

How many reports carry this code?

985 reports through August 2026, 43 of them in the latest 12 months.

Which brands appear most often?

Harmonic ACE (22), Ethicon (4), Stryker (3) and Sonicision (1). Widely used products collect more reports because more people use them.

Can the brands table be used to rank the devices?

No. 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." Brands differ in how many are in use, how long they have been sold and how reports are collected.

Where this comes from. Counts are built from the openFDA Device Adverse Event (MAUDE) bulk export released 28 Sep 2026, which holds reports FDA received through 31 Aug 2026. Brand, generic and manufacturer names are as written on the reports; product code names come from FDA's device classification. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
