An ultrasonic surgical instrument includes a first modular assembly including at least one operator input feature an ultrasonic transducer supported by the first modular assembly, and a second modular assembly configured to be removably coupled with the first modular assembly. The second modular assembly includes at least a portion of an end effector extending distally from a distal end portion of the second modular assembly. The instrument includes a mechanical lockout assembly configured to switch between at least an unlocked configuration and a locked configuration. In the locked configuration, the first modular assembly and the second modular assembly are partially coupled together such that the operator is physically prevented from activating the instrument using the operator input feature. In the unlocked configuration, the first modular assembly and the second modular assembly are completely coupled together and the operator is able to activate the instrument using the operator input feature.

Mechanical lockout for ultrasonic surgical instrument

An ultrasonic surgical instrument that includes a handle assembly including at least one user input feature; an ultrasonic transducer supported by the handle assembly, a shaft assembly configured to removably couple with the handle assembly, and a mechanical lockout assembly. The shaft assembly includes a distal end portion. The shaft assembly further includes an end effector extending distally from the distal end portion, and an ultrasonic waveguide configured to be acoustically coupled with the ultrasonic transducer. The mechanical lockout assembly is configured to move between at least an unlocked configuration and a locked configuration. In the locked configuration, the handle assembly and the shaft assembly are only partially coupled together physically preventing the user from activating the instrument using the user input feature. In the unlocked configuration, the handle assembly and shaft assembly are completely coupled together enabling the user to activate the instrument using the user input feature.
