It was reported that a light head disengaged from the spring arm.This occurred during a case and it was reported that a nurse went to the er for a possible concussion.The root cause of the issue was missing hardware, likely from an unknown service provider.The light is retained by a safety clip that is held in place by a rotated collar.This collar is held in place by an m3 screw, which utilizes a nut inside the arm.The m3 screw and nut were missing and the collar was raised, no longer covering the safety clip.The safety clip then backed out.The hardware was verified upon installation by stryker and there is no record of service performed or requested for this unit since installation.If any further information is found, a supplemental will be filed.
