Philips received a complaint from the customer in which it was stated that during a procedure where a pacemaker and a mechanical valve needed to be placed in the patient, the c-arm started moving without any command from the user.C-arm hit the patient and contaminated the sterile field.Furthermore the c-arc did not move anymore and did not respond on any commands, than the doctor decided to completely stop the system and the procedure was aborted.The patient needed to be sutured and will be called back in order to finish the procedure within 15 days.

Philips investigated this complaint and came to the following conclusion: on (b)(6) 2017, the field service engineer (fse), found that the tso (table side operation) was defective and replaced it.After replacing the tso, the system was working according to specification and was returned to the customer for use.A log file analysis, done on (b)(6) 2017 by our senior service specialist, shows that the system detected a soft collision.The system was rebooted by the user.After the reboot, tso (table side operation) commands were still active.Most likely, the accidental movement was activated by the customer/protection sheet or due to a defective tso module.Conclusion of the analysis: the c-arc made a spontaneous movement due to a defective tso module.This event was changed from serious injury to a non adverse event as a sepsis test that was taken did not show an infection.The patient was rescheduled and came back to the hospital for the procedure on (b)(6)2017.The procedure was performed successfully.
