Manufacturer Narrative

A cutting forceps 920005pk, lot# fr946636, was returned for evaluation due to no output after a few minutes.The device was received with the shaft straight, jaws open, and lock on.A visual inspection of the distal end found dried tissues on jaw consistent with use.The jaw symmetry is not balanced, and slightly bent, possibly due to grasping tissue with excessive force during use, but it is still functional.The jaw is fully wide open; the jaw aperture measurement was taken inside the first teeth of the jaw, measured at 0.339" (standard is.300¿ +/-.100¿) which is acceptable.The jaw mesh is not aligned.The insulation of the jaw legs was inspected and found jaw legs insulation with cracks exposing the electrodes beneath, but the flare is normal.The blade was tested multiple times, and did cut the dental dam without a problem.The ratchet lock on function is not working properly as it could not be pushed all the way; therefore, it could not keep the jaws in the fully closed position.When the trigger was pressed, the jaws stayed half closed.The device was plugged into the test generator; the generator displayed vp3;35 and the led on the forceps lit up; this is the correct default setting.The device did have sufficient energy at the jaws when the coagulation footswitch button was activated.The forceps was able to produce energy each time the footswitch was activated and worked as intended.Therefore, the reported complaint was not duplicated.The instructions for use state: "if forceps jaws come in contact with each other when the power is activated, the instrument will short out.Simply release the jaws so they are not in contact with each other and the forceps will become operational".The user most likely experienced the defect due to insulation failure in jaws, and the jaws being slightly bent most likely due to excessive force.Olympus will continue to monitor the field performance of this device.
