' s claims. (c1. 12844) My present invention relates geifiei'iailly to surgical appliances. Although this'de'vice is adapted to be used for a variety ot purposes, it has been especially devised for examination, treatiiint and surgical procedure at the signioid flexurevor region of the colon'in the human body, and Vit preferably employs aradio high-frequency eur'- rent which maybe readily controlled by the oper'- ator at al1 times."

The appliance which I have invented comprises a tubular body having 'a suitable -guideway that is adapted to receive an elongated semi-rigid conductor which carries electrode at its distal end, said electrodetbeing connected-tothe conductor by means of a readily eiible extension of conductive material which renders lit capable of universal movement or adjustment Within certain limits.- This pe'i'inits th ltiod, when it is projected beyond the distal end of the tubular body, to be controlled lto such extent thatv yit may be placed in proximity to the tissues come prised with a relatively large area within the colon. Means also arefpiovide'd in Connection with my surgical appliance lwhereby' the area be ing examined or treated may billuminatedfor observation by the operatord 1' I-h e electrode is adapted, among other things, tosar c'rrftldaguL late the tissue ina relatively short period of time and sterilize the same, and this' the Wall of the colon is in distefded position and under observation by thel operator who has f'll vision oi' the area underI treo;tfnerit.Y Provision is made whereby vapors, which are frequently cre# ated during treatment or operations 'of this char-Y acter, may lie-vented tromvthe cavitythr'oughthe medium of a suction'passag'e ayand'- thus avoid any fogging of the walls of -tlieappl'iance or of the lenses in an observation latter is employed in ance.

One of the special faturesboi this appliance is the electrode and its associated elements. This embodies a. normally curved, flexible conductor member extending from the distal end` of .the semi-rigid conductor member, which latter inem` connection with this amsn-4 ber constitutes the major.y portion of an elongated structure. Both of thes'e members `are hollow, and there is a small r'od. that is moved longitudinally Within the conductors and is adptaiwhile it is moving in the :flexible conductor towards the ele'ccurvedf' distal conductor, thereby adjusting theA eieetrode into af variety of operating positions;` it wiii be' seen that the eiectrodehas arniiversai adjust ent certain lmis S that i'i'.'I'tl'la'ylbrditld ih posi-2" is perferniedwniie telescope' when the kinddescribed herein that is Vdependable parts' that vare capable of withstandtion about the axis ci the Senn-'rigid and straight maior portion of the conductor structure.

onev of the aims 'cf improvements is te provide a surgical appliance of a novel character, and which is adapted to perform its required functions in an eii'ctive marmer, Anctiierobiect or aim is to provide a surgical appliance of the made ofsturuy and iii-g heavy duty and 'which may be readily sterili'z'ed by boiling `or byotheir methods. The im'- provements which I .naive described herein are of compact arrangement; they are convenient to operate and adjust to the desired posit-ions; and

lthe appliance is economical toproduce so that it maybe manufactured and sold at a 'competitive retail price to the user. t yThe before-'mentioned and other objects,

The guide pipe I 3 is adaptedtoreceive' and hold an instrument 'or accessory that"V u'pplied ,'With anqelectric current of the hig'l'i-freduency. radio instrument' by' a suitable feed. co

tails thereof yare shown in enlarged formin Figures 8, 9,.etc. H I. .1. -f -v i.

The device which is-shown comprises an'f'elo'ngated tube 3| of insulation suchas hardf'rubber, Bakelite (a resinous or phenolic condensation product), or any other suitable material that may be adapted for thepurposedesired. The .diameter of the tube 3| issuch that said tube maybe readily inserted intothe guidel pipe"|3, and it is of such length that its ends. will protrude beyond the ends of .the'tubular body l0 preferablyin the manner shown in the.` drawings "(Figure 1), wherein the protrudingportion of the proximal end is considerably longer than `.at .the distal end so that. said proximal portion may be. provided with instrumentalitiesfor manipulatingtthe instrument. i .i i As shown in enlarged detailin Figure 8, :the hard rubber or Bakelite tube telescopes upon and envelops an elongated tube32 of suitable conductive material, or metal, andfits end (to the left in Figures '7 and 8), carries a flexible member 33 that is adaptedvto. be moved or adjusted.into a variety of positions relative to and about the axis of the instrument. This member 33 is preferably a wire of ne `or small gauge that is wound-in' a spiral to form a flexible. hollow cylinder. The Wire is preferably.v spring' metal. and prior'to being tempered, and. after the spiralA has been formed, the member is shaped into an arcuate or curved form which will become permanentafter the temperingprocess has been completed, with the result :that said member :has .a normally curved axis such as suggested in dotted linesiin Figure 8 of the drawings. t f Y. M

One end of the-flexible member 33 is `inserted into the bore of the metal tube 32 .and is brazed, soldered or otherwisepermanently attachedl so that the hollow interior of thecoil forms a continuation ofthe bore ofthe metal tube 32, the other or free end of the ilexible member has'an electrode 34 anchored to it in any suitable'manner to close the outer free end and also to be in electrical connection with the metal coil33 'that forms the flexible member, so that-the electric current is transmitted from the metal tube 32 to the electrode 34. As illustrated in the drawings, the electrode 34 is spherical or globular in shape, but it will be appreciated .that other shapes may be used if it should be dictated for a particular type of use. 'I'he high-frequency radio current which is transmitted along the metal tube 32 and through the flexible extension (coil) 33 to the electrode 34, heats the latter to the desired temperature for the surgical procedure for which the instrument has been designed, and when said electrode is placed in contact with or close to the tissue it will cause a desiccation or coagulation thereof. In order to protect and insulate the coiled Wire extension 33, it is preferably surrounded by a jacket or sleeve 35 of relatively'fsoft or elastic rubber between the terminal electrode 34 and the end edge of the hard-rubber or Bakelite tube 3| so that said sleeve will readily conform to the shape of said flexible extension 33 and move with it when the latter is adjusted.

The normally curved or arcuate extension or iiexible member 33 which carries the electrode 34 at its end is adapted to be adjusted, by a, Warping action, into a variety of positions around the axis of the instrument and it is therefore capa- Ible of universal movement within certain limits. This adjustment or warping is accomplished by inserting a straight element longitudinally through the metal tube 32 and into the hollow flexible extension which will' progressively straighten the ourveor arc of said 'extension be' ginning at its anchored endnear the distalend of the inner-.metal tube 32 of the instrument and lmoving towards lthe electrode carried at the end lof f the iiexible member ,33. will move the electrode 34towardsfthe axis lof: the .instrument untilit has been alignedtherewith.. i.

The element which I prefer to employ-for per--V forming the function of warping theflexible ex.` tension 33 is an elongated wire or small rod- 36 that is of less diameter than. the inside diame. ter of thetube 32, and it is of such length that it will. extend fromy the free end portion of 4the iiexibleextension `33 and project from the-prox# imal end of said 4tube 32 whereit is provided with. an enlargement 31 of suitable insulating. material which constitutes A`a linger-grip by which the rod is manipulated. ..--An elongated,

tubular `gasket 38 surrounds the portion of. the rod 36 adjacent theinger-grip enlargement 3l, which .gasket .is of pliable material ,of a diame-` ter toV snugly vit within ythe proximal. end portion of. the tube 32. and thereby closey thel latter but at the same time permit the rodjto be in serted into the tube .and to be adjusted long i tudinally therein while itis performing; its func,-V tion of -warping the flexible'extension-.33'.4

`The end of the instrument opposite the elec.

'trede is inserted longitudinally through and anchored in the lateral horizontally .disposed arm 38 of a substantially Lg-shaped holder orvhandle.

- formed of hard-rubber or Bakelite, the other or longer arm 39 of said holder being disposed` oblique to the arm 38 and being provided with a longitudinal atial bore 40 that extends to near the top thereof. The lower open end of said bore 46 has an electric terminal connector 4| inserted and anchored in it with a portion projecting axially therefrom. s There is a .laterally disposed vent stub. 42 integral with the arm 33 of the L-shaped holder, which said stub has a rela-V tively small vborew43uthat communicates athits., inner portion with the bore 40 of the holder arm 38, and the tube 44 of a suction-bulb 45.,.isy adapted to be engaged over said ,stub .llthe purpose of which will later bev explainedmherein.

The tubular portion of this instrument, which' comprises the telescoped outer insulating tube 3|-` i and the inner metal tube 32, is of a length sol that, when the instrument has been inserted into its guide-pipe I3 until the holder arm 38 abuts the ilange on the obturator cylinder ID, the opposite ends of said tubes 3| and 32 will project out of the guide-pipe I3 and protrude slightly beyond the adjacent end of the obtura.- tor cylinder |0. There is a suitable clearance between the rod 36 and the inner metal tube 32, so that a. passageway 46 is provided within the elongated portion of the instrument which said passageway 46 is utilized to effectively vent the vapor, smoke, and the like, which may be created in performing the surgical procedure within the cavity. In order that this passageway 46 may communicate with the cavity, the tubes 3| and 32 are provided with one or more transversely disposed bores 41 at a location beyond the end of the guide-pipe |3. The opposite or outer end portions of the tubes are provided with a. discharge port 48 through which the vapor, etc., is emitted into the bore 40 of the arm 39 of the holder, and from thence said vapor is Withdrawn through the hollow vent stub 42 by the manipulation of the suction bulb.

This warping A recess or slot 49 is formed longitudinally in the insulating outer tube 3l, which said slot ex-Y tends with the holder arm'38 and the latter covers said slot. A conductor wire 50 is placed in said slot in contact with and is anchored to -the porconductor wire 50, the interior of `the holder,

alongside the-tubular members 3| and 32 of the l instrument, is channeled or grooved as at I to providefor thedisposition of the said wire 50. In this arrangement the electric current received bythe terminal plug 4I passes'through. successive portions of the instrument, such as the wire 5U,

the metal inner pipe 32, and the flexible iconductor 33, to the electrode 34.

Communication between the passageway 4E and the bore 40 of the arm 39 Yof the proximal head is established by forming a long longitudinal slot 52 in the conductor tube 32, which slot registers at one end with the small discharge port 48 in the insulating tube which leads into bore 40 of the head. At its other end said slot 52 extends beyond the inner end of the tubular gasket so that the vapor or the like will be by-passed alongside said gasket to the port 42.

What I claim as new is:

l. In a surgical appliance, ya flexible ductor of normally arcuate form; al hollow rigid conductor anchored `at`one end of said arcuate conductor in tangent relation thereto, said rigid conductor having vent ports at its distal portion; an electrode at the free end of said arcuate' conductor and normally eccentric to the axis of said rigid conductor; a rod movable longitudinally in said conductors, said rod during movement in said flexible conductor adapted to straighten the latter to move said electrode towards the axis of said rigid conductor, said rod having less diameter than the bore of said rigid conductor to provide an air-passageway therebetween com# municating with said vent ports; and suction means communicating with said air-passageway at the proximal portion of said -rigid conductor, said means adapted to exhaust vapor and the like from said air-passageway.
