Abstract: A surgical instrument includes a body assembly, a shaft assembly that releasably attaches to the body assembly, and an end effector at a distal end of the shaft assembly. The body assembly includes a first electrical contact and a first sealing portion. The shaft assembly includes a second electrical contact and a second sealing portion. The first and second electrical contacts are configured to electrically couple together to establish an electrical connection therebetween when the shaft assembly is attached to the body assembly. The first and second sealing portions are configured to sealingly engage one another when the shaft assembly is attached to the body assembly to establish a liquid-tight seal that surrounds the electrical connection.

Abstract: Various aspects of a generator, ultrasonic device, and method for estimating and controlling a state of an end effector of an ultrasonic device are disclsoed. The ultrasonic device includes an electromechanical ultrasonic system defined by a predetermined resonant frequency, including an ultrasonic transducer coupled to an ultrasonic blade. A control circuit measures a complex impedance of an ultrasonic transducer, wherein the complex impedance is defined as Z g  ( t ) = V g  ( t ) I g  ( t ) . The control circuit receives a complex impedance measurement data point and compares the complex impedance measurement data point to a data point in a reference complex impedance characteristic pattern. The control circuit then classifies the complex impedance measurement data point based on a result of the comparison analysis and assigns a state or condition of the end effector based on the result of the comparison analysis. The control circuit estimates the state of the end effector of the ultrasonic device and controls the state of the end effector of the ultrasonic device based on the estimated state.

Abstract: An ultrasonic surgical instrument that includes an ultrasonic transducer, a handle assembly supporting the ultrasonic transducer, a clamp arm assembly, and a mechanical lockout assembly. The handle assembly includes a housing and an ultrasonic blade acoustically coupled with the ultrasonic transducer. The clamp arm assembly includes a clamp arm. The mechanical lockout assembly is configured to switch between at least an unlocked configuration and a locked configuration. In the locked configuration, the handle assembly and the clamp arm assembly are not completely coupled together and the operator is physically prevented from activating the instrument using an operator input feature. In the unlocked configuration, the clamp arm assembly and the shaft assembly are completely coupled together and the operator is able to activate the instrument using the operator input feature.

Abstract: 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.

Abstract: 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.

Abstract: An ultrasonic surgical instrument and method of assembly with a predetermined alignment includes first and second modular assemblies and an electrical lockout. The first modular assembly includes at least a portion of an end effector configured to manipulate a tissue. The second modular assembly includes a transducer power circuit and an activation switch electrically connected to the transducer power circuit. The electrical lockout is electrically connected to the transducer power circuit and configured to inhibit the activation switch from powering the ultrasonic transducer with the first and second modular assemblies misaligned from the predetermined alignment such that the first and second modular assemblies are in a locked-out state. The electrical lockout is further configured to allow the activation switch to power the ultrasonic transducer with the first and second modular assemblies in the predetermined alignment such that the first and second modular assemblies are in an operational state.
