Detectable hand switch and surgical handpiece |
摘要 |
A handpiece and system having a surgical handpiece adapted to perform an operation on a patient, the surgical handpiece having a primary circuit being driven by an applied signal. A controller is operatively coupled to supply operating power to the surgical handpiece. A hand switch is operatively coupled in conjunction with the surgical handpiece to at least partially control an operation of the surgical handpiece. The switch has a secondary resonant circuit receiving the applied signal from the primary circuit and couples a response signal back to the primary circuit. Detection circuitry, operatively coupled to primary circuit, is responsive to a characteristic parameter of the response signal indicative of the presence of the hand switch in proximity of the surgical handpiece. |
