Disclosed herein is an electrosurgical device including a handle at a proximal end and an elongate shaft coupled to the handle and extending distally from the handle. The device also includes a distal working end, including a return electrode and an active electrode supported by an insulative spacer, the insulative spacer separating the return and active electrode. The active electrode has a planar surface that is distal facing and defines a maximum planar surface length. The insulative spacer is generally tapered between the return electrode and active electrode. The insulative spacer has a planar stabilizing surface on a device first side that has a length that extends along the longitudinal axis, extending from a distal-most end of the return electrode to a leading edge surface of the active electrode. This length is at least as long as the maximum planar surface length.

Electrosurgical device

Variable aspiration control in surgical procedures. At least one example is a method of performing a surgical procedure, the method comprising: driving, by a surgical controller, a motor within a handpiece coupled to a resection instrument, the driving causes mechanical resection of tissue by the resection instrument; aspirating, by a peristaltic pump associated with the surgical controller, fluid and tissue fragments through a suction lumen of the resection instrument during the resection of tissue; and modulating, by the surgical controller, speed of the peristaltic pump during the driving and aspirating, the modulating responsive to an interface device defined on an exterior surface of the handpiece.
