The device was not returned to stryker sustainability solutions for evaluation.As the device was not returned for evaluation, inspection was unable to be performed.A review of the dhr supports that the device met all inspection and test criteria prior to release from stryker.The reported event could be attributed to: excessive force applied, contact with hard object or other improper handling, activated electrosurgical instrument melts part of device.The instructions for use (ifu) state: general: these instruments are only intended for use by individuals with adequate training and familiarity with minimally invasive techniques.For further information about techniques, complications and hazards, consult the medical literature.Minimally invasive instruments may differ in diameter from manufacturer to manufacturer.When minimally invasive instruments and accessories from different manufacturers are employed together, verify compatibility prior to initiation of the procedure.Become familiar with specific model of trocar and cannula prior to employing it in a surgical procedure to avoid damage to patient, to operator or to instrument.-before beginning the procedure, verify overall compatibility of all instruments and accessories.Breakage: damage to the instrument can lead to patient injuries.Always inspect instrument carefully for overall integrity before use.Do not use excessive force.Careful handling of instruments is necessary to avoid damage or breakage.Inspect the instruments for any damage.Do not use the instrument if any damage is noted.Return the instrument and packaging to stryker sustainability solutions if it is not in acceptable condition for surgery.A comprehensive understanding of the principles and techniques involved in laser, electrosurgical, and ultrasonic procedures is essential to avoid shock and burn hazards to both patient and medical personnel and damage to the device or other medical instruments.Trocar insertion/withdrawal: very little pressure may be required to complete entry once partial entry has been obtained.Excessive pressure could cause injury to the internal structures.The obturator is designed with the optical feature to minimize the risk of penetrating injury to intraabdominal and intra-thoracic structures.Observe standard precautionary measures for all obturator insertions.Establish the primary puncture site and using standard surgical procedure create an incision which allows the trocar to be introduced.Loss of control during entry may possibly result if the incision is inadequate, due to the increasing resistance of insertion and required penetration force.Insert the obturator through the incision using a 30º to 90º rotating motion.Apply continuous but controlled downward pressure on the obturator.¿ keep organs out of reach of trocar penetration by ensuring a suitable positioning of the patient¿s body.The reported event will continue to be monitored through post-market surveillance.Should the device become available for return, the complaint will be reopened.
