Fluoroscopy switching device
First Claim
1. An apparatus for performing a surgical procedure involving endoscopy and fluoroscopy, comprising:
- a switching device having a video output for connection to a video monitor;
an endoscope having a video output connected to said switching device;
a fluoroscope having an X-ray generator, said fluoroscope further having video output connected to said switch device;
said switching device being operable to select from between said video output from said endoscope and said video output from said fluoroscope for output to said video monitor; and
means operative concurrently with selection by said switching device of said video output from said endoscope for deactivating said X-ray generator of said fluroscope.

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 fluoroscope and endoscope are connected to a switching device. 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. 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.
