It was reported that in operating room 7, there was a chromophare light that has become loose and appeared ready to fall from the spring arm.A stryker field service technician (sfst) was dispatched for investigation.When the sfst arrived at the account, he found that the surgical light had already been removed by hospital staff, but he was unable to locate the light or the mounting hardware.The sfst revisited the account 3 days later to reinstall the light.The technician noted that the account did not provide the original safety segment hardware, so he proceeded with the reinstallation by using safety segment hardware from his mobile inventory.After ensuring the light was properly secured to the spring arm, a functional test was performed, and the equipment was found to be working to specification.The equipment was then returned back to service and the issue was resolved.The sfst interviewed the hospital staff to determine how the keeper clip became missing.None of the hospital staff knew how the issue happened or if another vendor had been performing maintenance on the equipment.The installation history for the surgical light system was reviewed and it was found that the unit was installed on (b)(6) 2018.The service history for the suspension was also reviewed, and there were no service tickets found, indicating that the suspension has not been serviced by stryker personnel since installation.Although the exact root cause of this issue is unknown, the most likely root cause would be improper service and maintenance by hospital personnel.There was no injury or adverse event reported.
