Event or Problem Description
It was reported that a patient scheduled for open-route extended right hepatectomy, in which the surgeon requested a 17 cm harmonica focus long clamp in his special supplies.At the time of use in the liver section, the tip of the harmonic was divided in two, so it stopped working.The surgeon requested to replace it with another clamp, as the procedure was still to be finished and, without a tip, the clamp does not work properly and can be dangerous for the patient.There were no patient consequences.
Additional Manufacturer Narrative
(b)(4).Date sent: 5/12/2026.D4 batch #: a97m4h.Corrected data: d4 expiration date, udi#.Investigation summary: the product was returned for evaluation.Visual inspection and functional testing were conducted on the returned device.The device was returned with the distal tip of the blade broken off and not returned.The remaining blade portion was scratched and with evidence of contact with metal in or out of the operative field.During functional testing on gen11, an alert screen was displayed.A probable cause of the device stop activating and displaying an alert screen is blade damage.The manufacturing records were reviewed and the manufacturing/packaging criteria were met prior to the release of this batch.Probable causes of blade damage, including breakage, are external contact during pre-op or general use, blade contact with other devices, staples, or clips during the procedure, or using any means other than the blade wrench to attach or detach the blade.Once minor blade damage has occurred, subsequent activations may increase damage severity and can result in not passing the pre-run test followed by an alert screen, such as ¿tighten assembly¿, ¿blade error detected¿ or ""relaxed pressure on blade"" followed by a ¿replace instrument¿ screen later in the procedure, and continued usage can result in a broken blade.A manufacturing record evaluation was performed for the finished device batch a97m4h, and no non-conformances were identified.
