Embodiments relate to circuitry to provide amplitude modulated waveforms in electrosurgical devices. The circuitry can be included in an electrosurgical generator device to provide the amplitude modulated waveforms to an electrosurgical probe coupled with the electrosurgical generator device.

An electrosurgical instrument with smoke evacuation, having an electrode, a suction lumen, and a plurality of slots connected to suction lumen, in which the slots may be longer than they are wide and wider than they are thick. The electrosurgical instrument may have the slots arranged longitudinally about its central axis, and the suction lumen may be wider than the slot widths.

A combination of a chamber wall and the flexible membrane defines a pump chamber in a diaphragm pump. The pump chamber includes one or more internal surfaces that are modified to include a pattern of a pattern of channel surface regions. The channel surface regions provide unobstructed pathways to a respective opening disposed on an internal surface of the chamber wall. For example, as discussed herein, presence of the channel surface regions ensures that the facing of the flexible membrane does not needlessly stick (as a result of residual suction) to an inside surface of the chamber wall during a portion of the pump stroke in which negative pressure is applied to a backing of the flexible membrane. In other words, the channel surface regions distribute relief pressure along the inside surface of the pump chamber wall.

A fluid flow resistance assembly includes a fluid pathway. A width of the fluid pathway orthogonal to a flow of fluid through the fluid pathway varies along its length. Positioning of one or more ports at different locations over the fluid pathway at different locations controls a flow rate of fluid.
