Handpiece interlock and logic control for ultrasonic surgical system
First Claim
1. For an ultrasonic surgical system couplable alternatively to a first ultrasonic handpiece having a first configuration and operable at a first ultrasonic frequency, a second ultrasonic handpiece having a second configuration which is different than the first configuration, and a third ultrasonic handpiece operable at a second ultrasonic frequency which is different than the first ultrasonic frequency, a logic control system comprising:
- a handpiece connector adapted to connect alternatively to the first, second and third ultrasonic handpieces,said handpiece connector including a prewiring means,said prewiring means including a first electrical connection for the first ultrasonic handpiece, a second electrical connection for the second ultrasonic handpiece, and a third electrical connection for the third ultrasonic handpiece, said first, second and third electrical connections being different from each other,a logic control means electrically connected to said first, second and third electrical connections,said logic control means, when an ultrasonic handpiece operable at the first ultrasonic frequency is connected to said handpiece connector, causing energy of said first ultrasonic frequency to be delivered to the connected handpiece,said logic control means, when an ultrasonic handpiece operable at the second ultrasonic frequency is connected to said handpiece connector, causing energy of said second ultrasonic frequency to be delivered to the connected handpiece,said logic control means, when an ultrasonic handpiece having the first configuration is connected to said handpiece connector, causing a first indicator signal associated with the first configuration to be generated, andsaid logic control means, when an ultrasonic handpiece having the second configuration is connected to said handpiece connector, causing a second indicator signal, which is associated with the second configuration and is different than said first indicator signal, to be generated.

Abstract
A handpiece connector cooperates with the logic control circuit in an ultrasonic surgical system to distinguish types of handpieces, to indicate types of handpieces, to control differing operating frequencies for such differing handpieces, and to provide logic signals for controlling other system parameters dependent on the type of handpiece selected. A handpiece connector is prewired in a manner which is electrically indicative of one of several parameters to identify the selective handpiece. A logic control circuit, when connected to the handpiece, indicates that a handpiece is connected, indicates the type of handpiece so connected, indicates and controls the frequency of operation pertinent to that handpiece, and controls other system operating parameters related to the selected handpiece.
