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： An apparatus includes a body, a shaft assembly, and an end effector. The end effector includes an ultrasonic blade and a clamp arm assembly. The ultrasonic blade is in acoustic communication with an acoustic waveguide of the shaft assembly. The clamp arm assembly is pivotable toward and away from the ultrasonic blade. The clamp arm assembly includes a clamp pad and an electrode. The clamp pad is configured to compress tissue against the ultrasonic blade. The clamp pad has a proximal end, a distal end, and a pair of lateral sides extending from the proximal end to the distal end. The electrode is operable to apply RF energy to tissue. The electrode extends along both lateral sides of the clamp pad. The electrode further extends around the distal end of the clamp pad.

摘要： Aspects of the present disclosure are presented for a medical instrument configured to adjust the power level for sealing procedures to account for changes in tissue impedance levels over time. In some aspects, a medical instrument may be configured to apply power according to a power algorithm to seal tissue by applying a gradually lower amount of power over to time as the tissue impedance level begins to rise out of the “bathtub region,” which is the time period during energy application where the tissue impedance is low enough for electrosurgical energy to be effective for sealing tissue. In some aspects, the power is then cut once the tissue impedance level exceeds the “bathtub region.” By gradually reducing the power, a balance is achieved between still applying an effective level of power for sealing and prolonging the time in which the tissue impedance remains in the “bathtub region.”

摘要： Devices and methods are described herein for providing enhanced power to a surgical device from a secondary power supply that operates in parallel to a primary power supply that provides power for therapeutic functions of the device. The secondary power supply can provide additional power for the therapeutic functions of the device, and/or it can provide power for non-therapeutic functions of the device such as sensors, displays, motors, etc. Subsystems powered by the primary power supply can be wholly isolated from subsystems powered by the secondary power supply, thus helping to prevent faults in one subsystem from affecting the other and providing secondary power without the need to modify the subsystems powered by the primary power supply. According to any of the systems described herein, additional power can thus be supplied to the device without affecting the structure and/or function of existing subsystems configured to supply primary power.

摘要： An end effector has a first jaw member that includes a first electrode, and second jaw member that includes a second electrode, an electrically conductive member located at the distal end of either the first jaw member or the second jaw member, and an electrically insulative member located either on the first jaw member or the second jaw member. The electrically conductive member is configured to define a distance between the first and second electrodes along the length of the first and second electrodes, the electrically conductive member having a first stiffness. The electrically insulative member is located either on the first jaw member or the second jaw member and is sized and configured to engage tissue. The electrically conductive member has a first stiffness and the electrically insulative member has a second stiffness. The first stiffness is greater than the first stiffness.

摘要： A surgical instrument for supplying energy to tissue may comprise a handle, a trigger, an electrical input, and a shaft extending from the handle. The surgical instrument may comprise an end effector first and second tissue engaging surfaces that are slanted with respect to a transection plane. The end effector may, for example, have an electrode defining a V-shaped cross sectional profile. The end effector may comprise a plurality of raised surfaces that are received by a plurality of indentions when the end effector is in the closed position. The end effector may comprise a cutting member having a plurality of bands.
