CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims the benefit of the filing date of U.S. Provisional Patent Application Serial No.62/832,001 filed by the present inventors on April 10, 2019. [0002] The aforementioned provisional patent application is hereby incorporated by reference in its entirety. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

[0003] None.

BACKGROUND OF THE INVENTION

Field Of The Invention

[0004] The present invention relates to gas-enhanced electrosurgical systems, and more particularly, to a front panel assembly for an electrosurgical generator.

Brief Description Of The Related Art

[0005] A variety of different electrosurgical generators are known. U.S. Patent No. 4,429,694 to McGreevy disclosed an electrosurgical generator and argon plasma system and a variety of different electrosurgical effects that can be achieved depending primarily on the characteristics of the electrical energy delivered from the electrosurgical generator. The electrosurgical effects included pure cutting effect, a combined cutting and hemostasis effect, a fulguration effect, and a desiccation effect. Fulguration and desiccation sometimes are referred to collectively as coagulation. [0006] Another method of monopolar electrosurgery via argon plasma technology was described by Morrison in U.S. Patent No. 4,040,426 in 1977 and McGreevy U.S. Patent No. 4,781,175. This method, referred to as argon plasma coagulation (APC) or argon beam coagulation is a non-contact monopolar thermoablative method of electrocoagulation that has been widely used in surgery for the last twenty years. In general, APC involves supplying an ionizable gas such as argon past the active electrode to target tissue and conducting electrical energy to the target tissue in ionized pathways as non-arcing diffuse current. Canady described in U.S. Patent No. 5,207,675 the development of APC via a flexible catheter that allowed the use of APC in endoscopy. These new methods allowed the surgeon, endoscopist to combine standard monopolar electrocautery with a plasma gas for coagulation of tissue.

[0007] Yet another system is disclosed in U.S. Patent Application Publication No. 2013/0296846, which disclosed a system for simultaneously cutting and coagulating tissue. Another system, referred to as a“cold atmospheric plasma” system, is disclosed in U.S. Patent Application Publication No.2014/0378892.

[0008] A gas-enhanced electrosurgical generator is disclosed in WO 2018/191265 entitled“Electrosurgical Gas control Module.” The gas-enhanced generator has a housing made of a sturdy material such as plastic or metal similar to materials used for housings of conventional electrosurgical generators. The housing has a removable cover. The housing and cover have means, such as screws, tongue and groove, or other structure for removably securing the cover to the housing. The cover may comprise just the top of the housing or multiple sides, such as the top, right side, and left side, of the housing. The housing may have a plurality of feet or legs attached to the bottom of the housing. The bottom of the housing may have a plurality of vents 118 for venting from the interior of the gas-enhanced generator. On the face of the housing there is a touch-screen display and a plurality of connectors for connecting various accessories to the generator, such as an argon plasma probe, a hybrid plasma probe, a cold atmospheric plasma probe, or any other electrosurgical attachment. There is a gas connector for connecting, for example, a CO2 supply for insufflating an abdomen. The face of the housing is at an angle other than 90 degrees with respect to the top and bottom of the housing to provide for easier viewing and use of the touch screen display by a user. A power module and one or more of the gas control modules may be mounted within the gas-enhanced electrosurgical generator. A gas pressure control system for controlling a plurality of gas control modules is within the gas-enhanced electrosurgical generator SUMMARY OF THE INVENTION

[0009] In a preferred embodiment, the present invention is an electrosurgical generator housing. The generator housing has a configurable front panel with a body having a front face, a top, a bottom, a right and a left side, wherein the front face has an opening for receiving a touchscreen display, the opening for receiving a display being at an angle of less than 90 degrees relative to the bottom of the body. The configurable front panel further has a plurality of docks in the front face, each dock being configured to receive an accessory plug module. The front panel may have a plug module in each of the docks in the front face. Each plug module may an alignment groove on one or both outer sides and at least one of the docks has a corresponding alignment ridge or ridges on its interior sides. The plug modules may have a fluid connector and an electrical connector or just a fluid connector or just an electrical connector. One or more of the plug modules may be a blank plug module having no connectors.

[0010] The configurable front panel further may have a slot for receiving a printed circuit board and a shield between the slot for receiving a printed circuit board and the plurality of docks. A printed circuit board may be secured in the slot of receiving a printed circuit board.

[0011] The gas-enhanced electrosurgical generator housing further may have a base, a back and a cover, wherein the base, back and cover form a compartment and wherein the base has a support structure for securing a gas module and a power module within the compartment. Still further, there may be a shield between the front panel and the compartment.

[0012] The front panel provides structure for placing the display/tablet/user interface in the frame without falling out. The configurable front panel further provides a new arrangement for how different plugs fit in the panel. Still further, the present invention decreases electromagnetic interference (EMI).

[0013] Still other aspects, features, and advantages of the present invention are readily apparent from the following detailed description, simply by illustrating a preferable embodiments and implementations. The present invention is also capable of other and different embodiments and its several details can be modified in various obvious respects, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature, and not as restrictive. Additional objects and advantages of the invention will be set forth in part in the description which follows and in part will be obvious from the description or may be learned by practice of the invention.
