Abstract
An apparatus and method is disclosed for preventing accidental overradiation of a patient in surgical procedures involving both fluoroscopy and endoscopy. Video outputs from the endoscope and fluoroscope are connected to a switching device. The endoscope generates a video signal having a first video format, and the fluoroscope generates a video signal having a second video format. The physician uses the switching device to select from between the endoscope video output and the fluoroscope video output for viewing on a video monitor which accepts a video signal of a predetermined video format. The switching device is operable to convert at least one of the endoscope video signal or the fluoroscope video signal to the predetermined video format which the monitor accepts. When the endoscope video output is selected for viewing, the switching device automatically deactivates the X-ray generator of the fluoroscope. When the switching device is actuated to select the fluoroscope video signal for viewing on the monitor, the switching device automatically reactivates the X-ray generator. In this manner, overradiation of the patient during periods when the fluoroscope is not being used is avoided.
