Foot switch and output system having foot switch
First Claim
1. A surgical system including a foot switch and an apparatus main body having a function of producing active surgical output,the foot switch comprising:
- a pedal;
an output command signal generating section generating an output command signal when the pedal is operated;
a foot switch communication section performing communication directly with the apparatus main body;
a monitoring section monitoring a state of the output command signal generating section;
a transmit power adjusting section adjusting transmit power of the output command signal in the foot switch communication section;
a warning signal indicating section indicating a warning signal;
a control section controlling the output command signal generating section and the warning signal indicating section based on a monitoring result of the monitoring section; and
a storage battery supplying electric power to the output command signal generating section, the foot switch communication section, the transmit power adjusting section, the warning signal indicating section, the monitoring section, and the control section;
the apparatus main body comprising;
a main body communication section performing communication directly with the foot switch;
an output producing section producing active surgical output in accordance with the output command signal transmitted to the main body communication section from the foot switch and received by the main body communication section; and
a receiving-condition detecting section detecting, as a receiving condition, receive power of the output command signal in the main body communication section and generating a signal indicative of the detected receiving condition,whereinthe transmit power adjusting section adjusts by temporal variation the transmit power stepwise with a predetermined increment and at predetermined time intervals on the basis of a comparison result between a predetermined level settable at any value, and the signal indicative of the receive power, the signal being detected by the receiving-condition detection section, transmitted from the main body communication section and received by the foot switch communication section in order to reduce electric power supplied by the storage battery and to keep the receive power around a constant level,the output command signal generating section is configured to stop generating the output command signal when the transmit power exceeds a specified upper limit value,the warning indicating section is configured to generate the warning signal when the transmit power exceeds the specified upper limit value,the transmit power adjusting section is configured to adjust the transmit power such that the transmit power does not fall below a specified lower limit value even if the signal indicative of the receive power is at a level exceeding the settable predetermined level, andthe receiving-condition detecting section is configured to command the transmit power adjusting section to increase or reduce the transmit power when receive power of the output command signal in the main body communication section is out of a range between predetermined levels settable to arbitrary value.

Abstract
The foot switch includes a pedal, an output command signal generating section generating, when the pedal is operated, an output command signal commanding an apparatus main body having a function of producing active output to produce active output, a communication section performing communication with the apparatus main body, a transmit power adjusting section adjusting transmit power of the output command signal in the communication section, and a storage battery supplying electric power to the output command signal generating section, the communication section and the transmit power adjusting section. The transmit power adjusting section adjusts the transmit power on the basis of a signal indicative of receiving-condition of the output command signal in the apparatus main body, the signal transmitted from the apparatus main body and received by the communication section.
