Wake-up system and method for powered surgical instruments
First Claim
1. An electromechanical surgical system, comprising:
- an end effector configured to perform at least one function;
an adapter assembly being arranged for selectively interconnecting the end effector and a hand-held surgical instrument;
a one-wire bidirectional serial communications interface extending through the end effector, the adapter assembly, and the hand-held surgical instrument; and
the hand-held surgical instrument including an instrument housing defining a connecting portion for selectively connecting with the adapter assembly;
a master circuit coupled to the one-wire bidirectional serial communications interface and configured to identify or control the adapter assembly or the end effector;
a power source coupled to the one-wire bidirectional serial communications interface and configured to provide power to the adapter assembly or the end effector;
a first switch configured to connect the master circuit to the one-wire bidirectional serial communications interface;
a second switch configured to connect the power source to the one-wire bidirectional serial communications interface; and
a controller including a processor configured to control operation of the hand-held surgical instrument, the controller having a wake-up pin connected to the one-wire bidirectional serial communications interface, the wake-up pin is configured to receive a presence pulse from the end effector or the adapter,wherein the first switch is connected to a first pin of the processor and the second switch is connected to a second pin of the processor.

Abstract
The present disclosure is directed to an electromechanical surgical system having an end effector and an adapter assembly for selectively interconnecting the end effector and a hand-held surgical instrument. A one-wire bidirectional serial communications interface or bus extends through the end effector, the adapter assembly, and the hand-held surgical instrument. The hand-held surgical instrument includes a master circuit coupled to the bus and configured to identify or control the adapter assembly or the end effector. A power source is couplable to the bus and configured to provide power to the adapter assembly or the end effector. A first switch connects the master circuit to the bus and a second switch connects the power source to the bus. A processor controls operation of the hand-held surgical instrument. The controller has a wake-up pin connected to the bus and is configured to receive a presence pulse from the adapter or end effector.
