摘要： An ultrasonic surgical instrument comprises a reusable housing including an internal transducer and an internal end effector rotation assembly. An exemplary rotation assembly is a ratchet and pawl assembly, which allows the transducer to rotate in a first direction but not in a second, opposite direction. The end effector, including an integral torque wrench, is attached to the transducer to form a single unit that is rotatable relative to the housing. The transducer attaches to a stationary cable via slip rings. The cable communicates with a generator, which provides electrical power to the transducer. The transducer converts the electrical power into ultrasonic vibrational energy, which is transmitted to the end effector.

摘要： An ultrasonic device with increased efficiency as a result of substantially increased pressure uniformity across individual PZTs and through the PZT stack. Specifically, the PZT stack is uniformly compressed by way of a bolt having a head that has a surface area roughly equal to the surface area of the individual piezoelectric elements. The bolt is further combined with an aft end bell that has a reduced surface contact with the bolt head and a larger surface contact with the adjacent piezoelectric stack.

摘要： A surgical instrument comprises a body assembly and an end effector. The body assembly includes a control module, an orientation sensor communicatively coupled to the control module, and an energy component. The energy component is operable to activate the end effector at a plurality of energy settings. A storage device is communicatively coupled to the control module and includes a plurality of gesture profiles and corresponding energy settings. The control module is configured to set the energy setting of the energy component to a corresponding energy setting in response to a correlation between the output of the orientation sensor and a gesture profile. In some versions, the control module modifies the energy setting based upon output from a force sensor that measures the force on the end effector. The control module may also decrease the energy setting in response to an anomalous acceleration or deceleration detected by an accelerometer.
