A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Surgical instrument with selectively actuated gap-setting features for end effector

Various aspects of a generator, ultrasonic device, and method for estimating a state of an end effector of an ultrasonic device are disclosed. 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(t)=V(t)/I(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.

A surgical instrument includes a body, a shaft assembly, an end effector, a clamp actuator, and a blade cooling system. The end effector has a clamp arm and an ultrasonic blade coupled with an ultrasonic transducer. The clamp arm is configured to selectively move from a first actuator position toward a second actuator position thereby directing movement of the clamp arm from the open position toward the closed position, respectively. The cooling system is operable to deliver fluid coolant to the ultrasonic blade to thereby cool the ultrasonic blade while the clamp actuator remains in the first actuator position.

Blade cooling gas/fluid storage

A surgical apparatus comprises a body, a user input feature, a shaft assembly, an end effector, and a blade cooling system. The end effector comprises a clamp arm and an ultrasonic blade that may be coupled with an ultrasonic transducer. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The cooling system is operable to deliver liquid coolant to the ultrasonic blade to thereby cool the ultrasonic blade. The user input feature is operable to both actuate the clamp arm and actuate the cooling system.

Features to drive fluid toward an ultrasonic blade of a surgical instrument

An ultrasonic surgical instrument includes a body, an ultrasonic supported by the body, a shaft extending distally from the body and defining a shaft axis, a waveguide extending distally through the shaft, and an end effector arranged at a distal end of the shaft. The end effector includes an ultrasonic blade coupled to a distal end of the waveguide and having a primary blade treatment surface configured to treat tissue, and a clamp arm coupled to the distal end of the shaft. The shaft and the waveguide are selectively rotatable relative to one another about the shaft axis through a predefined range of angular motion between an assembly state and an operational state. In the assembly state, the clamp arm and the primary blade treatment surface are rotationally offset from one another. In the operational state, the clamp arm and the primary blade treatment surface are rotationally aligned.

Ultrasonic surgical instrument with pre-assembled acoustic assembly

A surgical instrument includes a shaft assembly, an ultrasonic blade, and a cleaning device. The shaft assembly includes a first tube and an acoustic waveguide. The first tube has a first inner diameter and a distal end. The waveguide has a first outer diameter. The waveguide extends within the first tube. The first outer diameter of the acoustic waveguide and the first inner diameter of the first tube together define a gap. The ultrasonic blade extends distally from the distal end of the first tube. The acoustic waveguide is configured to communicate ultrasonic energy to the ultrasonic blade. The cleaning device is configured to actuate within the gap to thereby clean at least a portion of the shaft assembly and/or at least a portion of the ultrasonic blade.

Ultrasonic surgical instrument with blade cleaning feature

A surgical instrument includes a reusable assembly having an inner tube and an ultrasonic blade positioned within the inner tube. The inner tube includes at least one opening to receive a sterilization fluid therethrough for sterilizing the ultrasonic blade within the inner tube. The surgical instrument further includes a sterilization detection system to determine whether the reusable assembly has been sterilized during a sterilization cycle. A seal is selectively couplable with the at least one opening of the inner tube to fluidly seal the at least one opening for inhibiting bodily fluid from entering the at least one opening during a surgical procedure.

Dual sterilization and temperature based sterilization detection

An apparatus includes a body, a shaft assembly, and an end effector. The shaft assembly includes an outer tube, a proximal inner tube member, a distal inner tube member, and an acoustic waveguide. The end effector includes an ultrasonic blade and a clamp arm. A first portion of the clamp arm is pivotably coupled with a distal end of the outer tube. A second portion of the clamp arm is pivotably coupled with a distal end of the distal inner tube member. The outer tube is configured to removably couple with the body and the distal inner tube member is configured to removably couple with the proximal inner tube member such that the outer tube, the distal inner tube member, and the clamp arm are configured to removably couple with the body and the remainder of the shaft assembly and end effector as a unit.

Ultrasonic surgical instrument with removable shaft assembly portion

A surgical instrument is disclosed including an end effector, a generator configured to deliver adaptive energy, a mode selector switch having a plurality of surgical modes, a closure switch configured to control the end effector, and a counter configured to count a number of closure switch activations. The surgical instrument is configured to communicate a selected surgical mode of the mode selector switch and the number of closure switch activations from the counter to the generator. The surgical instrument is configured to receive the adaptive energy from the generator based on the selected surgical mode and the number of closure switch activations. The generator is configured to deliver the adaptive energy to the surgical instrument closer to a start of an activation cycle for the selected surgical mode as the number of closure switch activations increases.
