Abstract:

A cartridge assembly to couple an electrosurgical device to treat tissue with an electrosurgical unit includes a cartridge member to operate with a power delivery apparatus of the electrosurgical unit and a fluid delivery apparatus of the electrosurgical unit. An electrosurgical unit includes a power delivery apparatus and a fluid delivery apparatus arranged to operate with a cartridge member to be located in a cartridge receptacle of the electrosurgical unit. An electrosurgical device includes a first electrode spaced alongside the second electrode, with each electrode having a blade shaped member. Each blade shaped member has opposing sides bounded by edges, with the edges having a medial edge and a lateral edge. At least one fluid outlet is adjacent each blade shaped member, and each fluid outlet is in fluid communication with a fluid passage. The device can be operated as either a bipolar device or a monopolar device and includes a switch to inhibit capacitive coupling to one of the electrodes when the other electrode is used in monopolar fashion.

US Classification:

606 33, 606 41

Abstract:

A bipolar electrosurgical device includes a shaft and an electrode tip coupled to a distal end of the shaft. At least a portion of the electrode tip extends distally beyond the distal end of the shaft and includes an insulator extending between a first electrode and a second electrode. The first electrode is configured to he an active electrode and the second electrode is configured to be a return electrode. The electrode tip can include a substantially conically-shaped portion, or can include a spherical portion and a cylindrical portion protruding from the spherical portion at a non-zero angle with respect to a longitudinal axis of the shaft. The substantially conically-shaped portion can include at least a portion of one of the first electrode and the second electrode. The distal end of the shaft can include a fluid outlet opening to provide fluid from a fluid source onto the first electrode and the second electrode.

US Classification:

295921, 156 731

Abstract:

A method of producing an electrosurgical device is disclosed. Opposing longitudinal clamshells are formed, and each clamshell includes a face having a generally planar major portion. Longitudinal grooves are formed in a clamshell, and an electrical conductor in a disposed in a groove. The faces are aligned to form an electrical passage including the electrical conductor in the groove and a spaced-apart fluid passage with another groove. The clamshells are welded together to form a shaft member such that the electrical passage and the fluid passage are fluid tight along a major longitudinal portion of the shaft. Electrodes are attached to the distal end of the shaft and are in electrical communication with the electrical conductor.
