摘要： A surgical instrument includes a body, an ultrasonic blade, a clamp arm assembly, and a detent assembly. The clamp arm assembly includes a clamp arm pivotably coupled with the body at a pivot assembly. The clamp arm is operable to compress tissue against the ultrasonic blade. The detent assembly is configured to provide tactile resistance to pivotal movement of the clamp arm relative to the body beyond a predefined pivot angle. The detent assembly is configured to permit pivotal movement of the clamp arm relative to the body beyond a predefined pivot angle upon application of a force sufficient to overcome the tactile resistance

摘要： An apparatus comprises a body assembly and a shaft extending distally therefrom. The shaft defines a longitudinal axis. The apparatus further comprises an acoustic waveguide and an articulation section coupled with the shaft. A portion of the articulation section encompasses a flexible portion of the waveguide. The articulation section further comprises first member and a second member that is longitudinally translatable relative to the first member. The apparatus further comprises an end effector including an ultrasonic blade in acoustic communication with the waveguide. A distal portion the ultrasonic blade is disposed in a first direction away from the longitudinal axis at a bend angle. The end effector also includes a clamp arm that is coupled with the first member and the second member, and an articulation drive assembly operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis in the first direction.

摘要： An apparatus comprises a body, a shaft assembly, an end effector, and a shield member. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade and a clamp arm. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is movable toward the ultrasonic blade to compress tissue against the ultrasonic blade. The shield member is selectively movable from a first position to a second position in response to movement of the clamp arm toward the ultrasonic blade. The shield member is configured cover at least a first portion of the ultrasonic blade in the first position. The shield member is configured to uncover the first portion of the ultrasonic blade in the second position.

摘要： Various forms are directed to systems and methods for dissection and coagulation of tissue. A surgical instrument includes an end effector configured to dissect and seal tissue at a distal end thereof, and a selector switch having a plurality of surgical modes. A generator is electrically coupled to the surgical instrument and is configured to deliver energy to the end effector. Each surgical mode of the selector switch corresponds to an algorithm for controlling the power delivered from the generator to the end effector, and each algorithm corresponding to the plurality of surgical modes is configured to allow a user to control the power output level of the generator.

摘要： A surgical instrument includes a body, a shaft, and an end effector. The shaft extends distally from the body. The end effector is located at a distal end of the shaft. The end effector includes an active feature configured to operate on tissue. The body includes a drive feature operable to drive the active feature of the end effector. The body is operable to selectively couple with a variety of power sources such that the drive feature may receive electrical power form a battery or from a corded power source, based on a user's preference. The body may include a handpiece that has a socket configured to receive a battery or cable adapter. The body may removably receive various kinds of shaft assemblies to provide various operating modalities. The shaft assemblies may include user interface features.

摘要： Ultrasonic surgical instruments having an ultrasonic transmission waveguide with a tapered width are described. This longitudinal taper allows the ultrasonic transmission waveguide to also function as an acoustic horn that focuses and amplifies the ultrasonic vibrations produced by an ultrasonic transducer to an ultrasonic surgical blade.
