V This invention-relates to surgical instru- Inents and particularly to that class known as 'l iigh-frequency vesical' electrodes. An ob- 1 a n tural opening.

The high frequency .electrodeof this inren on is intended to he used pr marily n combination with a cystoscope introduced through .a supra. pubic cystotomy opening, the latter "for the purposeof observing and directing the action of the electrode during diathenmie fulgnration, The electrode of this in ntion is us d anset r y for thesurgical treatment of obstructions and def rarities atthe neck of thebladder, and for growthsrin its interior, In the drawi s c Fig, 1 shows t e m nn r o sing he i1 .strurlnent for removing a growth at the vesial orifice.

In the embodiment of my invention shown in the drawings A is a cylindrical tube of insulating material preferably vbakelite or similarphenol condensation product. Tl1lS tube or sheath is of an external diameter approximating the minimum average internal surgical diameter of the duct in which it is to be inserted, for example the urethra.

A, as is also the tubular: extension C.) These parts are all securely and rigidly secured together as by moulding o'r'otherwise seas to form; an integral whole.

The electrode proper comp-ri' tip I. screwed to a metal member 2.' The part 2 is pivotally connected to each of twlo longt'hhi metal, rods Sand .4. Of the rods 3 and 4c, theone designated 3 isseeurely and rigidly held in ahead D of hakelite or similar insu'lating materialuwhil'e the other rod 4 passes freely through D and is] in its turn secured rigidly to terminal E. Terminal E is also of bakelite or similar substance. The Part C on head B fits into the axially arranged socket Son head 1).

By means of the construction 'first d'escrib ed the tip or beak of the, electrode is in axial position when the parts D E are slightly separated, but on member E'be ing mo edYtoward'D the rod 4 will also, be

The radially arranged connector for leading the high frequency current'is shown at 20 and consists of an insulating cylinder of Fbakelite or similar material inserted in head E. spring split-clip arrangement 21 connected to rod 4; so'that as one side of the source 'of'high frequency current is connected to clin 21 the current will be also connected to the electrode tip 1.

In Fig. 1 there is shown a manner of using WVithin this cylinder isa metal V the instrument for fulguration of obstruc tions at the vesical orifice. Here V is the cystoscope inserted through the supra-pubic cystotomy opening. By inserting the cystoscope through the sinus as shown, the action of the electrode can bedefinitely and accurately observed and directed.

The active electrode is connected to one side of a high frequency source of current as indicated at M and the other side of the source is connected'to the indifferent electrode N bearing against the back of the patient. What I claim is; 1. A vesical electrode for high frequency current comprising the combination of a fixed rod, a secondrod movable relative thereto, a terminalbeak pi'votally attached to both of said rods, and means for moving the one rod relative to the other to angularly swing said beakf 2. A vesical electrode for high frequency current comprising the combination of a v I fixcdrod, a second rod axially movable relative thereto, a terminal beak pivotally attached to both of said rods, and means for moving the one rod relative to the other to an ularlyswing said beak.

vesical electrode for high frequency current comprising the combination of a' sheath, a rod in the sheath and fixed therein, a cautery tip mounted on the rod, a sec ond rod in the sheath movable relatively to the first rod and attached to the tip, and means for moving the second rod.

' 4. A vesical electrode for high frequency current comprising the combination of a fixed rod, a second rod movable relative thereto, a terminal'beak pivotally attached to both of said rods, means for moving the one rod relative to the other to'angularly swing said beak, and means to fix the beak in angular position.

a 5. A vesical electrode for high frequency current comprising the combination of a sheath, a rod in the sheath and fixed there in, a cautery tip swingably mounted on the rod, a second rod in the sheath movable relatively to the first rod and attached to the tip, and means for moving the second rod.

6. A vesical electrode for high frequency current comprising the combination of a sheath, a rod in the sheath and fixed therein, a cautery tip swingably mounted on the rod, a second rod in the sheath movable current, comprising an elongated sheath of V insulating material, a metallic rod in the sheath and fixedtherein, a cautery tip pivotally connected on the rod, a second rod in the sheath movable relatively to the first rod and pivotally connected to the tip', means for moving the second rod, and means for connecting a source of high frequency current to the first rod.

' 10. A vesical electrode forhigh frequency current; comprising an elongated sheath of insulating material; a metallic rod in the sheath and fixed therein; a smooth, tapered,

blunt-nosed, metallic, cylindrical, cautery tip swingably connected at one side, of its rear end to the rod; a longitudinally movable second rod in the sheath having a piv- .otal connection with said tip at the rear swingable connection; means for moving said second rod; means for fixing the'lon gitudinal movement of the second rod relative tothe first rod and so the angular position of the tip; and means for connecting a source of high frequency current to the first rod.
