摘要： A shaft assembly is disclosed which is selectively attachable to a variety of surgical systems, such as a handle of a surgical instrument and an arm of a robotic system, for example. The shaft assembly comprises, one, a firing member operably couplable with the surgical systems which is configured to perform a firing stroke and, two, a manually-operable crank for retracting the firing member after a portion of the firing stroke has been performed.

摘要： Various forms are directed to systems and methods for coagulation and dissection of tissue. A surgical instrument includes an end effector configured to seal and dissect tissue at a distal end thereof and a generator circuit that is configured to deliver energy to the end effector. A force sensor is in communication with the end effector and is configured to measure a force being applied to the tissue by the end effector. The energy delivered to the end effector is dynamic based on a determination of the type of tissue interacting with the end effector. The tissue type is determined based on a tissue coefficient that is calculated based on the measured force applied to the tissue by the end effector, the ultrasonic motion of the end effector, and a rate of heat generated by the end effector.

摘要： A surgical instrument system is disclosed which comprises a distal end and a staple cartridge assembly comprising staples removably stored therein. The instrument system further comprises a firing drive including an electric motor and a firing member operably couplable with the electric motor. The electric motor is operable to advance the firing member toward the distal end during a staple firing stroke to eject the staples from the staple cartridge. The electric motor is operable to retract the firing member away from the distal end during a retraction stroke. The surgical instrument system further comprises a manually-operated bailout mechanism operable to perform the retraction stroke in lieu of the electric motor, a controller, and a display in communication with the controller. The controller is configured to display the progress of the retraction stroke when the firing member is being manually retracted by the bailout mechanism.

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： Various exemplary surgical adjuncts with medicants affected by activator materials are provided. In general, an adjunct is provided with at least one medicant that is configured to be activated by an activator material. The adjunct can be delivered to a tissue of a patient, where the adjunct can be implanted. Various activator materials can be configured to activate the at least one medicant retained by the adjunct, the activation causing any one or more of a variety of actions. For example, the at least one medicant can be activated so as to yield at least one of a signal and/or an effect on the adjunct.

摘要： A surgical instrument is disclosed comprising an end effector, a frame, an articulation system configured rotate the end effector relative to the frame, and a firing system configured to perform a firing stroke within the end effector. The firing system is selectively engageable with the articulation system to rotate the end effector. In such instances, the firing system cannot perform the firing stroke until the firing system has been operably decoupled from the articulation system.

摘要： A surgical instrument includes an ultrasonic transducer assembly comprising a coupling portion laterally movable at an ultrasonic frequency. In addition, the surgical instrument includes an ultrasonic transmission waveguide extending from the coupling portion and an ultrasonic treatment element defining a cutting surface, wherein the ultrasonic treatment element extends from the ultrasonic transmission waveguide, and wherein the lateral movement of the coupling portion is in a direction perpendicular to a plane defined by the cutting surface of the ultrasonic treatment element.
