摘要： A surgical instrument includes a shaft assembly and an articulation control assembly. The shaft assembly includes an articulation section that is configured to deflect a distal end portion from the longitudinal axis. The articulation control assembly includes an articulation control member and a transmission assembly. The articulation control member is rotatably mounted relative to the shaft assembly. The transmission assembly is operatively connected between the articulation control member and the articulation section of the shaft assembly. The transmission assembly is configured to transmit selective manipulation of the articulation control member to the articulation section and selectively actuate the articulation section. The articulation control assembly is configured to lock without selective manipulation of the articulation control member to thereby inhibit actuation of the articulation section and unlock with selective manipulation of the articulation control member to thereby actuate the articulation section.

摘要： A surgical apparatus includes a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and a rigidizing member. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide includes a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section includes a first member and a second member. The second member is longitudinally translatable relative to the first member. The end effector includes an ultrasonic blade in acoustic communication with the waveguide. The rigidizing member is configured to selectively engage at least a portion of the articulation section to thereby selectively provide rigidity to the articulation section.

摘要： An ultrasonic surgical system is disclosed including an end effector, an elongate shaft, an articulation joint, and an articulation system. The end effector is rotatable relative to the elongate shaft about the articulation joint. The articulation system includes a distal plate, a first cable, a second cable, and a gear. The distal plate is configured to articulate toward a first side of the gear based on the gear rotating in a first direction and articulate toward a second side of the gear based on the gear rotating in a second direction. The end effector is configured to articulate in a first articulation direction about the articulation joint based on the distal plate articulating toward the first side of the gear. The end effector is configured to articulate in a second articulation direction about the articulation joint based on the distal plate articulating toward the second side of the gear.

摘要： An apparatus comprises an end effector, a shaft assembly, and an interface assembly. The end effector is coupled with the shaft assembly. The shaft assembly comprises a translating member extending through the shaft assembly. The interface assembly is operable to engage the shaft assembly and comprises a plurality of drive shafts and a rack. One of the drive shafts is operable to drive the rack along a path that is parallel to the longitudinal axis of the shaft assembly. A plurality of racks may be used to rotate the shaft assembly, articulate the shaft assembly, and/or drive the translating member through the shaft assembly to thereby actuate the end effector.

摘要： Circular stapling instruments and anvil assemblies. The anvil assemblies may have collapsible anvil support members that may be inserted through an opening in a patient and then expanded to be attached to an anvil plate assembly that has a staple-forming surface thereon. The anvil support member is attachable to the anvil plate assembly in such a way that when the anvil assembly is coupled to the stapling head of a circular stapler, the staple-forming surface is in substantial registry with the staples supported in the stapling head. A variety of different anvil support members and anvil plate assemblies are disclosed.

摘要： Devices and methods for articulating a distal end of a surgical device are provided. In one exemplary embodiment, the device includes an articulation joint that includes both an inner guide and an outer sleeve. The inner guide includes one channel extending therethrough that receives both a cutting mechanism and a closure band. Further, an outer surface of the inner guide, in conjunction with the outer sleeve, can define two additional channels that each receive an articulation band for articulating an end effector coupled to the articulation joint. The outer surface of the inner guide can include a plurality of ribs that also help define the two additional channels. Further, the outer sleeve can include a plurality of slots formed in it to improve flexibility and stability. Additional configurations of articulation joints, and configurations of components of a surgical device, are also provided, as are methods for using the same.

摘要： A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The articulation section includes a collar that is located distal to a nodal portion of the waveguide and is operable to deflect the end effector away from the longitudinal axis. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The articulation drive assembly is operable to drive articulation of the articulation section. The articulation drive assembly comprises at least one translating articulation driver coupled with the collar. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue even when the articulation section is in an articulated state.

摘要： The disclosure provides a method of manufacturing a flexible circuit electrode assembly and an apparatus manufactured by said method. According to the method, an electrically conductive sheet is laminated to an electrically insulative sheet. An electrode is formed on the electrically conductive sheet. An electrically insulative layer is formed on a tissue contacting surface of the electrode. The individual electrodes are separated from the laminated electrically insulative sheet and the electrically conductive sheet. In another method, a flexible circuit is vacuum formed to create a desired profile. The vacuum formed flexible circuit is trimmed. The trimmed vacuum formed flexible circuit is attached to a jaw member of a clamp jaw assembly.

摘要： Aspects of the present disclosure include control systems of an electrosurgical system for managing the flow of fluid, such as saline, and rates of aspiration or suction, in response to various states of conditions at a surgical site. The control system(s) may monitor and adjust to impedance at the surgical site, temperature of the surgical tissue, and/or RF current of electrodes, and may account for certain undesirable conditions, such as the electrodes sticking. The control systems may include various automatic sensing scenarios, while also allowing for several manual conditions.
