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 instrument includes a housing, an ultrasonic transducer support by the housing, and an integrated usage indicator. The housing is configured to removably connect to a shaft assembly. The ultrasonic transducer is configured to be acoustically connected to a waveguide and operated a predetermined number of use cycles. The integrated usage indicator is operatively connected to the housing and includes a used state indicator. The used state indicator is configured to indicate to a clinician in a used state when the ultrasonic transducer has been operated at least the predetermined number of use cycles for limiting usage of the ultrasonic transducer to the predetermined number of use cycles.

摘要： An end-effector and a surgical instrument including the end-effector are disclosed. The end-effector includes a clamp arm and an ultrasonic blade configured to acoustically couple to an ultrasonic transducer and to electrically couple to a pole of an electrical generator. The clamp arm incudes a clamp jaw, a cantilever electrode, and a clamp arm. The cantilever electrode is biased in a direction toward the clamp jaw and the clamp arm includes a retainer to oppose a biasing force and maintain the cantilever electrode in a substantially flat configuration relative to the ultrasonic blade. A skirt may be disposed around the clamp jaw. The clamp arm pad may include multiple support elements arranged in multiple rows to support the cantilever electrode.

摘要： An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises 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 comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.

摘要： Aspects of the present disclosure are presented for a single surgical instrument configured to grasp, seal, and/or cut tissue through application of therapeutic energy, and also detect nerves through application of non-therapeutic electrical energy. A medical device may include two jaws at an end effector, used to apply therapeutic energy and to perform surgical procedures. The therapeutic energy may be in the form of ultrasonic vibrations or higher voltage electrosurgical energy. One of the jaws may be configured to cut tissue through application of the blade. In addition, one or both of the two jaws may be configured to apply nontherapeutic energy for nerve stimulation probing. The application of therapeutic energy may be disabled while the nontherapeutic nerve stimulation energy is applied, and vice versa. The nontherapeutic nerve stimulation energy may be applied to the use of one or more probes positioned near one or both of the jaws.

摘要： A method of fabricating an ultrasonic medical device is presented. The method includes machining a surgical tool from a flat metal stock, contacting a face of a first transducer with a first face of the surgical tool, and contacting a face of a second transducer with an opposing face of the surgical tool opposite the first transducer. The first and second transducers are configured to operate in a D31 mode with respect to the longitudinal portion of the surgical tool. Upon activation, the first transducer and the second transducer are configured to induce a standing wave in the surgical tool and the induced standing wave comprises a node at a node location in the surgical tool and an antinode at an antinode location in the surgical tool.

摘要： A surgical instrument includes an ultrasonic transducer, a shaft defining a longitudinal axis, and an end effector at a distal end of the shaft. The end effector includes an ultrasonic blade driven by the ultrasonic transducer to treat tissue with ultrasonic energy. A tissue treatment portion of the ultrasonic blade includes a linear blade region extending parallel to the longitudinal axis, a curved blade region extending distally from the linear blade region along a curved path that deflects laterally from the longitudinal axis, an upper treatment side, a lower treatment side, a first lateral side having a first sweeping side surface, and a second lateral side having a second sweeping side surface. The sweeping side surfaces define respective first and second side edges of a transverse cross-section of the tissue treatment portion, and are configured such that the first and second side edges are parallel to one another.
