Manufacturer Narrative
|
The complaint device was returned to stryker sustainability solutions for evaluation.The device was connected to scalpel generator, and failed with two "tighten assembly" errors (after which the assembly was tightened) and a "replace instrument" error.The device was examined further and a build up of tissue/fluid was noticed along the rod which can disrupt harmonic frequency and reduce cutting ability.The device did not operate as a result of a build up of fluid/tissue along the distal end of the inner rod.The cause of tissue/fluid build up is damage to the distal gasket; action is being taken to address this issue.

Manufacturer Narrative
|
The complaint device was returned to stryker sustainability solutions for evaluation.Inspection of the returned device revealed evidence of clinical use and an indention in the teflon pad.The scalpel was tested and failed with two "tighten assembly" errors (after which the assembly was tightened) and a "replace instrument" error.The device was disassembled, and the blade was inspected for cracks.A fracture was found in the blade.A review of the device history records supports that the device was unlikely to have been released from stryker with the reported failure mode.Therefore, the most likely root cause of the broken blade is incidental or prolonged activation against solid surfaces, such as bone, metal or plastic.The instructions for use state: "avoid contact with any and all metal or plastic instruments or objects when the instrument is activated.Contact with staples, clips or other instruments while the instrument is activated may result in cracked or broken blades.".
