ABSTRACT:
A medical surgery safety device used in connection with surgical insulting instruments and other operation room medical equipment. The safety device includes one or more remote unit attached to the surgical insulting instruments and the medical equipment and having an accelerometer for detecting a sudden motion of the medical equipment, and a radio frequency signal transmitter for transmitting a radio frequency signal upon detection of such sudden motion. The safety device also includes a base unit attached to a main surgical insulting instrument and having an accelerometer for detecting a sudden motion of the main surgical insulting instrument, and a radio frequency signal receiver for receiving the radio frequency signal from the remote units. The base unit also include a power inlet connected to an external electrical power source and a power outlet for providing electrical power to the surgical insulting instruments. The power to all surgical insulting instruments is interrupted, however, upon either the detection of the sudden motion by the accelerometer of the base unit or the reception of the radio frequency signal from the remote units.
