Ultrasonic probe deflection sensor
First Claim
1. An ultrasonic surgical instrument comprising:
- an ultrasonic probe configured to conduct electricity, the ultrasonic probe being positioned a predetermined distance from at least one tube and adapted to be operatively connected to an ultrasonic generator for vibration; and
a deflection detection circuit including a secondary power source and an indicator, the power source being configured to supply electrical current to the at least one tube, the ultrasonic probe, and the indicator, wherein the circuit is configured to close in response to the ultrasonic probe contacting the at least one tube when the ultrasonic probe is deflected toward the at least one tube thereby activating the indicator.
