My present invention relates-generally to surgical instruments-and-Has-particular reference to> surgical' instruments of the-type which are designed to- apply electrical'currents to the human body;
: Although I have^ herein1 illustrated and shall hereinafter describe a particular type of surgical instrument wherein the- operative electrode is in the-form of a pair of complementary jaws, never-/, theless-it will' be< understood- that the' broader phases of my invention are not-restricted to an. instrument having any specific character of electrode or electrodes.
The instruments-to'Wlliclr my invention relates arc of; the type-whereby-high frequency alternating current may be applied to the part of the human body to be treated-by means of an electrode arranged- usually at the forward' end of- an elongated stern or the like, this electrode1 member-being adapted for insertion into and- through a fenestrated eiidoscopic tube whereby the;; electrode operates through- the' fenestra.-- The electrode member usually- carries a< binding post at its rear end and is provided with;electrode-operat~ ing- mechanism* which extends- rearwardly along or through the stern • into association- with some sort1 of- manually-graspable control device. The Gui rent which flows through the-body from the electrode-is returned, to a. suitable source of- current by way of a relatively large'indifferent electrode applied to some convenient exterior port-ieir of-'the-body.
In the conventional type of instrument it has heretofore been almost universal practice' to construct1 ths instrument in- such' a- manner that the electeical1 connection between the electrode and the binding-post is effectively insulated fromithe remainder of the electrodermember, and especially from tae control' device which is wielded by tile- operator. It need hardly be pointed out that whatever insulation has been-heretofore used-has imposed" severe limitations upon the characteristics of the operative structure. Not only is-inEulatiDii usually, weak- mechanically, but it is-also relatively bulky and' cumbersome, especially where it is in the form of'quartz or similar vitreous material. Furthermore, only the simplest, types' of mechanical movements could'be;provided; for with any degree1 of economical success because of ;the obvious difficulties involved in proper-ly insulating the-electrode-and-the-bin ding post f renr the • operating mechanism: These difficulties Have been-especially difficult to > obviate in' connection- with- fbrcipated- instruments- whereih' a pair of cooperative-'-or complementary jaws of>
necessarily-great strengths have been sought to be used as operative electrodes .of the present char.-. acter.
My- present invention, is. predicated; upon-, the; discovery that the- use- of' a- proper type of.'high 5:. frequency current, especially where, the- oscilla*tions are properly and. effectively-sustained! at a maintained comparatively low voltage, permits; insulation to be dispensed with entirely; This remarkable phenomenon, due primarily, if not. io: solely, to-the present rapids development in. the relatively new art of: employing, high, frequency current for surgical purposes, has tremendously far-reaching effects; in connection; with the-art of iiistrumentananuf acture • and.design.. Not only. jgi may electrode instruments be provided, in greatly simplified forms, but' instruments with., entirely new characteristics .of operation and. structure may; be- manufactured: economically and; used^ with feasibility and; safety. For example, 20f my present: invention has-: enabled-; me; to; designs an entirely new type of electrode instrument, of; ftecipated; character, arid: it is-, this general type of instrument which;has. been - illustrated and will.! hereafter be described to.exemplify, the.general 25i nature of my presentlnvention.
It may thus-be stated-to be'a; more particular; object: of: my inveiition-to provide a- new/and improved type of: forcipated;surgical.:eleetrode characterized by great;'simplicity.; .remarkable strength; 30; compactness and: full- opportunity for complete; illuminated; visibility.
Whereas the art of "bloodlessly" cutting; or: punching-: diseased:tissue, or.'the like,.by means: of. jaw electrodes has; heretofore been;, highly unv 355, satisfactory and often utterly incapable: of; feasible accomplishment;, my present invention permits .suitably visualized;and;.illuminated;forcep) jaws to be employed iwith:.greafrease:and .efficiency as electrodes, of the character called: forr by 403 modern electro-surgery: My- present: invention] further permits; instruments.of this, type;- and' ofi other widely varying, types,, to;- be.'regularly employed with safety in routine;operatiye:practice..
From.5 its broader aspect: my. invention-consists 455 briefly in the provision^of a-new type=of• operative: electrode member which is-composed of."an:.elon^ gated'stem; a conductive electrode..at: its fonwar.d,' end, a binding-post and control:device at its rear? end) and electrodes-operating mechanismi between: 501 said'electrode and control,device, the.- entire memi>ber- being insertable as a; unit, into:' an: endoscopic tube; and1 the- several parts- thereof: being; assembled^ in mutually-' uninsulated relationship:. The: endoscopic: tube into which tiie: electrode; is-dn^ 5fc
