For the investigation the provided information, photos and technical reports were analyzed.A detailed technical information regarding the present malfunction scenario was already provided onsite by an involved dräger specialist.The affected device was not available for a detailed investigation.According to the technical report a fallen dräger surgical light sola 700 on an outsourced hospital employee during the post-surgery room cleaning process could be confirmed.No mechanical failures were identified at the junction of the dome with the spring arm, and while checking the affected operating room onsite, the items of the spring arm parts kit g94494 (lock and cover) were found.However, the locking screw that secures the lock protection cover (locking or securing sleeve) was not found.There were no structural or technical failure seen at the interior and exterior of the spring arm connection with the integral dome onsite.In the course of the investigation it can be concluded that due to the absence of the screw responsible for fixing the locking sleeve, during the cleaning process this part was moved upwards, exposing the locking segment that was released, causing the dome to yield.As the cover requires external action to move and is not located in a region where the equipment operates (region used to move the dome during surgery) the incident could not have occurred during a surgical procedure.This locking screw may have fallen off during other cleaning procedures during the last preventive which was held approximately one year before the incident.The light system connected to the spring arm cannot fall down spontaneously as due to the consistently vertical arrangement of the lower spring arm socket, it can be assumed that the spring arm locking sleeve located here will remain in its end position on the spring arm without manipulation or mechanical action from the outside, even if it is (incorrectly) not screwed on itself, due to the earth's gravitational pull, and thus prevents the locking element located under or behind the locking sleeve from falling out.A falling of light head can lead to a patient or user injury, in particular as reported in the present case.A disturbance of a surgical procedure is not known in this context.According to the instructions for use the arm and light system has to be checked regarding its operational readiness before each use.There is no apparent design or manufacturing error contributed to the described event.The number of similar cases, related to the same root cause, is within the expected range of the respective risk assessment and thus accepted.
