The device was not returned to stryker sustainability solutions for evaluation.It was stated the device was discarded at the user facility.As the device was not returned for evaluation, inspection/testing was unable to be performed.A review of the dhr could not be performed as the lot number and/or serial number was not reported.All stryker sustainability solutions reprocessed devices are sold as sterile and are validated to a minimum sterility assurance level in accordance to applicable iso standards.When the sterile barrier of any device is opened, the sterility of that device becomes a function of handling and surgical technique and is beyond the control of stryker sustainability solutions.Therefore, the most likely root causes are device mishandling during preparation prior to procedure causing contamination of non-biological particles/debris on the device and/or non-sterile techniques used.The instructions for use (ifu) state: warnings and precautions: - the use of these instruments requires a thorough understanding of the techniques and principles of laser, electrosurgical, and ultrasonic procedures.Inappropriate use may result in shock and burn hazards to both patient and medical personnel or damage to the device or other medical instruments.Check and ensure electrical insulation or grounding is not compromised.Do not immerse instruments in liquid unless it is designed and stated.- high temperatures at the distal end of the shaft can occur due to blood and tissue buildup between the blade and shaft.Remove any visible tissue to prevent burn injury.- avoid incidental and prolonged activation against solid surfaces (such as bone), which may result in blade heating and/or blade failure.- when the instrument blade is activated the blade tip is active and will cut and coagulate tissue.Care must be taken to avoid unintentional contact between the blade surfaces and surrounding tissues.-verify hemostasis after withdrawing instrument.If bleeding is still observed, employ appropriate techniques to achieve hemostasis.Assembly: - remove the instrument from the package and place it in a sterile work area using aseptic technique.Should the device become available for return, the investigation will be reopened.The reported event will continue to be monitored through post-market surveillance.(b)(4).
