ATTORNEY Patented Mar. 8, 1938 UNITED STATES ATENT OFFICEA SURGICAL NEEDLE AND HOLDER Mozes H. Marton, New York, N. Y. Application October 20, 1933, Serial No. 694,405

11 Claims,

The improved surgical instrument Comprising the present invention is primarily adapted for use as a depilator for the permanent destruction of hair bulbs which prevents further formation or growth of the hair after the bulb has been destroyed. The invention is, with or without modication, capable of other uses and the same may be employed, for example, in the permanent destruction of tissue underlying the skin, or in the coagulation or cauterization of tissue cells.

The principal object of the present invention is to provide an insulated surgical electrode, which is preferably in the form of a ne wire or needle, having its penetrating portion insulated, which enables one to cauterize, coagulate or destroy tissue cells located below the surface of the epidermis, without causing electrical injury to the epidermis itself.

With the uninsulated electrodes such as heretofore in use, that is to say, such electrodes as do not have the penetrating portion of the electrode insulated, this could not be done except at the secrice of a good deal of the overlying epidermis, which resulted in scariflcation and a change in the pigmentation of the aiected areas. Therefore, such results practically made futile the elforts to improve the appearance of the skin from an aesthetic point of view, and such results were also just as undesirable from a medical point of View. l

Other objects of the invention are to provide Van improved surgical electrode and holder to form a cauterizing instrument wherein the members thereof may be simply assembled and conveniently operated, and furthermore to provide a marked improvement in the electrode unit itself.

These being among the objects of the present invention, the same consists of certain features of construction and combinations of parts to be hereinafter described and then claimed with reference to the accompanying drawing illustrating one embodiment of the invention and wherein Fig. l is a side elevation of the complete instrument including the electrode and its holder;

Fig. 2 is an enlarged section of a portion of the instrument shown in Fig. 1 on the line 2-2 thereof;

Fig. 3 is a still further enlarged cross-section on the iine `3--3 of Fig. 2;

Fig. 4 is an enlarged detail section of a portion of the holder;

Fig. .5 is a longitudinal section of the electrode unit which includes the electrode;

Fig. 6 is a longitudinal section of the tip-mem- (ol. 12s-393.18)

ber of the holder which is adapted to receive the electrode of Fig. 5, these two figures being on a different scale, and

Fig. 7 is a longitudinal section of the electrode unit which is adapted to form part of the electrode.

The tubular holder or handle I of the instrument is provided with a `tapered tip-membe-r II also of tubular form, and these are both composed of non-conducting material which may be hard rubber. One end of the holder Il) is provided with a screw-threaded neck I0', the holder having a bore Illa. The holder and its tip-member may have a suitable length adapting them for their use. Tip-member I I is provide-d with an enlarged bore IIa to provide a skirt therearound and a smaller portion II of said bore is provided with a screw thread adapted to be en' gaged with the screw threaded neck Iii. That portion I lb of the bore which passes through the tapered part of the tip-member I I is of the smallest diameter and is adapted to receive the electrode to be hereinafter described. It will be seen that when the parts are threaded together the skirt portion around the large bore I 0a of the tip-member receives the adjacent larger portion of the holder Iii, there being a slide t between the two to permit the tip-member to be adjusted inwardly or outwardly on the holder IIJ. The out- Ward position of the tip-member is shown in full lines in Fig..2 and the inward position thereof is shown in broken lines.

In Fig. an electrode unit is illustrated, it being shown in position on the instrument in Figs. 1 and l2. The electrode includes `a thin metal tube I 2 at the outside thereof and an interior layer or covering I3 of insulating material around and sheathing a fine wire I4 which forms the metallic needle proper of the electrode, and theouter terminal of which slightly protrudes from the insulating covering I 3 while its inner terminal protrudes for a greater distance beyond the corresponding end of the insulating covering I3.

The insulation I3 of the needle proper may be formed of any suitable insulating material and is desirably formed from a length of glass tubing or other vitreous material. which may be drawn or moulded into-a small diameter so as to thoroughly encase, and to adhere to, the needle proper except for the two terminals referred to.

In Fig. 7 a unit is illustrated which may be characterized as a needle unit inasmuch as it may be manufactured as a separate article of manufacture, or the same may be combined with the outer metal tube I2 to provide a complete electrode unit, in which case the innei` terminal of the needle proper I4 is preferably connected by solder I8 with the metallic tube I2 so as to provide a suitable electrical connection between the two metal elements.

Suitable proportions with respect to the length and thickness of the electrode are important. The needle i4, as before stated, consists of a ne metallic wire, and it has been found in practice that good results are obtained with a ne wire of a ldiameter or" around 0.16 mm. The degree of protrusion of the point portion of the electrode proper beyond the insulation or layer I3 may in practice be approximately 1 mm. It is important that the penetrating portion of the electrode which is directly behind the point portion, and follows it into the skin, should be suitably formed and of proper proportions. Therefore the insulation is tapered down at I3 to a thickness that increases the diameter of the electrode to a barely perceptible degree.

Oi course, the drawing, except Fig. 1, shows the parts of the instrument as exaggerated in size, but the proportions substantially as stated are quite important.

Referring to Figs. 2 and 4 it will be seen that the threaded neck Iii of the holder Ii] contains a longitudinally split metallic tube I6, the slot I6 through which permits slight expansion or contraction of the tube I6. This tube is surrounded by a bushing il of suitable material which is fitted tightly into the neck I', and which reinforces and strengthens the neck. The split metal tube I6 is adapted to serve as a sort of clutch, inasmuch as when the tip member II is screwed back to the position shown in broken lines in Fig. 2, the electrode, Fig. 5, may be slid into such tube and clutched thereby so as to retain the same, with the tube I2 and the tube I6 in electrical contact. When so doing, the pliers used to insert the electrode are caused to grasp the outer end portion of the metal tube I2 which protects the insulation I3 against damage thereby. When the instrument is to be used for cauterization or the like, the tip-member II is adjusted tothe full line position shown in Fig. 2, or a little further if desired, to cover the metal tube I2 so that the hand of the operator which grasps the instrument is protected against electric shock. The grip of the split tube i6 on the inner end of the electrode is suiilcient to hold the same in using position and to permit the tip-member I I of the holder to be screwed inwardly or outwardly relatively to the electrode without shifting the electrode with it. By screwing the tip-member inwardly to the position shown in broken lines in Fig. 2, a suicient length of the metal tube i2 of the electrode is exposed so that pliers may be used by the operator to grip it and remove the electrode at any time desired.

A suitable insulated electrical conductor I9 is shown, which is provided at one end with a suitable plug IS for establishing a connection with the source of electricity. The linner endo the conductor I9 isl either secured by solder Ia, as shown in Fig. 4, or the end of the conductor may be plugged tightly into the adjacent end of the split tube and the conducting wires exposed and in electrical Contact with the split metallic tube I6, as shown in Fig. 2. It will therefore be seen that when the patient being treated establishes in any well known manner a circuit through the source of electricity as by a suitable electrode in contact with another part of the body of the patient, that the current flows through the wires of the conductor I9, the metallic sleeve or clutch I6, the metallic sleeve I2 of the electrode, the inner end of needle proper I4, and through the needle to that part of the body of the patient which is to be treated, whereby the exposed tip of the needle proper may be used for cauterization or the like. At the same time the terminal portion I3a of the insulation around the needle protects the skin of the patient against injury by the current, and it being of such a small diameter, say approximately twice that of the diameter of the needle proper, it can follow the extreme tip of the needle in penetrating the skin.

Obviously the invention may be modified more or less without departing from the scope of the appended claims.

What I claim as new is- 1. A surgical electrode comprising an insulated penetrating portion adapted to penetrate and extend into the skin, said insulated electrode having an exposed uninsulated tip of smaller diameter than the penetrative portion adapted to contact with a portion of an underlying body to be destroyed, and means for applying a destructive electric current to said portion through said uninsulated tip the relation of the uninsulated tip and the penetrating portion being such that the portion to be destroyed may be affected locally without damaging overlying skin tissues.

2.
