It was reported that during a robotic laparoscopic radical prostatectomy procedure, the image was lost momentarily, as if it had restarted.When the team attempted to virtually reverse the image, the endoscope buttons did not respond and stopped functioning.The team unplugged and reconnected the communication cable of the endoscope, which restored the image.However, the endoscope buttons remained non-functional.The team manually rotated the camera to resolve the issue.This resulted in a 10-minute delay.There was no patient injury.No negative impact in state of health reported.Cross reference mdr: 9610617-2025-01175.

The devices concerned (tc302 - image1 s d3-link, serial# (b)(6) and 26605aa - tipcam 1 s 3d lap, 0°, serial# (b)(6)) were not returned to the manufacturer for inspection.Therefore, a physical technical inspection was not possible, and a precise error analysis could not be carried out.The investigation could only be performed based on the available event information, which states that "during a robotic laparoscopic radical prostatectomy procedure, the image was lost momentarily, as if it had restarted.When the team attempted to virtually reverse the image, the endoscope buttons did not respond and stopped functioning.The team unplugged and reconnected the communication cable of the endoscope, which restored the image.However, the endoscope buttons remained non-functional.The team manually rotated the camera to resolve the issue.This resulted in a 10-minute delay.There was no patient injury." furthermore, the customer provided a photo of an error message which states that there was an endoscope failure.Based on the error message it is concluded that the device tc302 was not causative, because the error message indicates an endoscope error.As stated, a precise error analysis is not possible without the devices and according to the event information it is possible that the 26605aa tipcam camera was not primarily responsible for the system failure, as the camera, in combination with a computer-controlled robotic arm, forms a system network that failed for reasons which are not known.The event is filed under internal karl storz complaint id: (b)(4).
