Abstract

A control circuit for a surgical instrument includes a shaft control segment, a first electrical conductor configured to conduct a first electrical signal between the shaft control segment and a releasable surgical instrument cartridge, an electrosurgical energy control segment, a second electrical conductor configured to conduct a second electrical signal between the electrosurgical energy control segment and the releasable surgical instrument cartridge, and a connector electrically coupled to the electrosurgical energy control segment and configured to receive electrosurgical generator energy from an electrosurgical generator. The electrosurgical energy control segment is configured to detect a connection of the electrosurgical generator to the connector and to electrically isolate the shaft control segment from the electrosurgical generator energy when the electrosurgical energy control segment detects the connection of the electrosurgical generator to the connector.

Description

technical field [0001] The present disclosure relates to electrosurgical devices and, in various aspects, to modular circuits for conducting electrical signals therein. Background technique [0002] In surgical sealing and stapling systems, it may be useful to employ a modular design that allows a single handle assembly to be attached to multiple nozzle assemblies, and allows the nozzle assembly to be attached to multiple handle assemblies. Since the nozzle assembly will include various surgical instruments in the end effector, special circuitry in the nozzle may be required to allow the instruments in the handle assembly to control various functions in the end effector of the modular nozzle assembly. In some examples, each of the various surgical instruments can be designed to perform a specific surgical function, such as one or more types of tissue sealing functions. Additionally, it may be desirable to apply energy to the end effector that may or may not originate from t...
