ELECTRICAL SURGICAL INSTRUMENT.

' SPECIFICATION forming part of Letters Patent No. 463,785, dated November 24, 1891.

' Application filed January 15, 1891 Serial No. 377,859. (No model.)

To aZZ whom it may concern:

Be it known that we, FRANK L. CONNABLE and THOMAS V. HARPER, citizens of the United States, residing at Xenia, in the county of Green and State of Ohio, have invented certain new and useful Improvements in Electrical Surgical Instruments; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in electrical surgical instruments, as forceps and probes, whereby the aid of the electrical current is invoked in searching or probing for a foreign metallic body and in providing for signaling the contact of the instrument with the said body, the signaling continuing as long as such contact exists or the foreign metallic body is grasped by the instrument,but ceasing, of course, the instant such body he comes separated from the instrument. Thus.

much unnecessary pain and laceration are avoided, which result from the use of the ordi 2 5 nary forceps, where the sense of touch has to be alone relied upon and where the instrument frequently grasps a ligament or tendon.

In effecting the important results set forth we employ the appliances hereinafter ,disclosed.

Our invention is illustrated in the accompanying drawing.

Two steel strips a a, forming the jaws of the instrument, are insulated from each other by means of the insulating-strip b, and are inclosed in the rubber or other insulating tube 0, all of which extend from or near the bottom of the handle A to the topof the instrument. The metal tube cl fits loosely over this, and is provided at the upper end with an in sulating-thimble e, which fits in the tube cl tightly or is otherwise secured to it, and which fits or encircles the steel strips and their insulating-strip loosely enough to admit of its being moved up and down upon them easily. The other end of the tube cl is provided with the coarsely -vthreaded or spirallygrooved metal tube f and the thumb-nut g, by which it may be turned. The steel strips a a are rounded on their outer and flat on theirinner surfaces, so that when they and their insulating-strip b are finished, ready for the insu lating-t-ube 0, they present the appearances of a round rod or bar. The upper end of the steel strips are permanently sprung outward, 5 5 so that when the metal tube cl is drawn toward' the handle A the steel strips separate by reason of their normal spring-tension. The extreme upper ends of the'steel strips a a are bent in toward each other and are provided each with one or more sharp teeth or points, which, when the instrument is fully closed, overlap or pass each other slightly without coming into metallic contact with each other. The lower endsof the steel strips are secured to the handle A in any suitable manner, care being taken during the entire manufacture of the instrument to prevent any electrical connection or contact between the two steel strips. Thelower or handle ends of the steel strips are provided with suitable means for making connection to the respective poles of a battery D, which includes in its circuit a bell. F or buzzer or other suitable device for producing a signal when the cir- '75 cuit is closed. The lower or spirallyrgrooved end of the tube fenters the handle A and engages with a corresponding thread or spiral groove, or an in wardly-proj ecting stud, pin, or screw in the handle may engage with the thread or groove in the tube f, so that by turning the tube by means of the thumb-nut g the tube maybe moved up or down, and thus open or close the jaws a a.

The operation of the instrument is asfollows: The two steel strips being connected with the respective poles of a battery by means of a suitable plug or otherwise, the instrument is inserted into the wound with the jaws closed, as shown in the drawing, and when the jaws touch the bullet or any other foreign metallic body the circuit is closed and a signal given. The nut g is then turned, causing the jaws to open by reason of their normal spring-tension. IV hen opened suffi 5 ciently. to allow the foreign body to come within their grasp, they are then closed upon it by turning the handle in the reverse direction, which by forcing the tube (Z upward draws the jaws toward each other, the electrical signal being continuous as long as the metallic bodyis grasped by the instrument and ceasing immediately should it slip from its grasp.

Having thus described our invention, what we claim is 1. The electrical surgical instrument having the electrically-insulated jaws adapted to connect with the battery-wires and provided with approximately closed jaws, and the adjustable sleeve adapted to actuate or spread said jaws, substantially as set forth.

2. An electrical surgical instrument composed of the combination of steel strips, an

insulating central strip, an insulating-tube inclosing said strip, an outside adjustable sliding tube, an insulating-handle, and a battery connection, substantially as set forth.

3. An electrical surgical instrument composed, in combination, of steel strips a a, forming at upper end overlapping jaws, the insulated central strip 1), the inclosing insulatingtube 0, the outer tube (I, provided with a thimble 6 and adjusting thumb-nut g, the tube 1, which said thumb-nut turns, the handle, and a battery connection, substantially as set forth. a

In testimony whereof we affix our signatures in presence of two witnesses.

Correction in Letters Patent No. 463,785

It is hereby certified that Letters Patent No. 463,785, granted November 24,] upon the application of Frank L. Oonnable and Thomas V. Harper, of Xenia,

for an improvement in Electrical Surgical Instruments, was erroneously issu Frank L. Oonnable, Augusta Mason Connable, and Fannie M. Oonnable, as

owners of the invention; that said Letters Patent should have been issued to Frank L. Connable, Harper, said Harper being owner of one-fourth interest in said invention as shon the record of assignments in this Ofifice; and that the proper correction has been in the files and records of the case in the Patent Ofifice and should be read i Augusta Mason Gonnable, Fannie M. Oonnable, and Thonu Letters Patent that the same may conform thereto. Signed, countersigned, and sealed this 8th day of December, A. D. 1891.
