JONATHAN R. HAMILTON, OF MINNEAPOLIS, l.IINNESOTA,'ASSIGNOR OF ONE-HALF TO LYMAN R. PALMER, OF SAME PLACE.

ELECTRODE FOR FORMING CLOTS IN VARICOSE VEINS.

SPECIFICATION forming part of Letters Patent No. 373,399, dated November 15, 1887.

Application filed June 27, 1887.

To all whom, it may concern:

Be it known that l, JONATHAN R. HAMIL- TON, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Electrodes for Forming Clots in Varicose Veins, of which the following is a specification.

It is the principal object of my invention to produce a convenient and efficient device for forming clots in pile-tumors by means of an electric current.

Theinvention is illustrated in the accompanying drawings, in Wlll('.l1

Figure 1 is a side view of the device; and Figs. 2 and 3 are transverse sections on the lines 00 m and g y, respectively.

A in the drawings representsastem having its forward end, a, bent in a half-circle and provided with a platinum or other suitable point, a, and a shoulder, a

B is also a stem, placed parallel to the stem A, and arranged to slide in rubber or other non-conducting guides c c, that are secured to the stem A and have holes 0" 0, through which the stem B may slide. The forward portion of the stem is crooked outwardly, as at b, enough to bring its end in line with the axis of the backward projection of the part a, and the forward end of the stemB is also provided with a suitable point, a, and a shoulder, (L2. The shoulders a permit the points a only to enter the vein or tumor. The hole 0 in the guide 0 is square, as is also the portion of the stem which slides in it, to prevent the stem from turning. An adjustable stop, d, on the stem B regulates the extent of the forward movement of the part B, and so prevents the approach of the two points a beyond the desired limit. The stop d may be made adj ustable by means of threads I) on the stem, as shown, or by a thumb-screw in the stop eugaging the stem.

To the rear ends of the two stems are attached suitable holders, 0, having sockets in their ends for receiving the ends of the conducting-wiresf for introducing the electric current to the stems. The stems should have a coating of a suitable insulating substance.

In use the instrument is inserted through the anus by means of a speculum, and the points a are adjusted, so as to penetrate the walls of a hemorrhoid, and the electric current is then introduced, forming a clot or coagulation of the blood between the points c.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. An electrode for treating varicose veins, comprising two conductingrods, one of which has its forward end bent backward to the axial line of the other, means for longitudinal adjustment of the rods, and conductingwires connected to said rods, substantially as set forth.

2. An electrode consisting of the conducting-rod A, having the curved end a, the adjustable conducting-rod B, the points a and shoulders at on said rods, the guides c c, and the conducting-wires f, substantially as and for the purpose set forth.

JONATHAN R. HAMILTON.
