INSTRUMENT 1 Application filed February 18, 1930. Serial No. 429,299.

This invention relates to an improved surgical instrument and aims to provide an improved type of forceps which may be employed to advantage in numerous different associations, but which, consistent with'the embodiment of the invention hereinafter described and shown in the accompanying drawings, is preferably a forceps of the mas- It is a further object of the invention to.

construct a device. of this type by means of which, with the expenditure of minimum energy, a surgeon may be able to exert all force necessary to the performance of such steps of the operation as are capable of being accomplished through the instrumentality of the forceps, and in which the operation'of the forceps may be achieved in an extremely simple and positive manner.

Another object is that of providing such deviae in which the parts may be cleaned readily and thoroughly.

l Jith these and further objects in mind, reference is had to the attached sheet of drawings in which there is illustrated one practical embodiment of the invention, and in which:

Fig. 1 is a side elevation of forceps, and showing the parts thereof in open position;

Fig. 2 is an edge view thereof;

Fig. 3 is a sectional view;

Fig. t is a fragmentary view of those portions of the forceps which are adjacent the jaws, and showing the parts in closed or gripping position;

Fig. 5 is a view of the jaw portions separated from each other; and I Fig. 6 is a perspective view of one of the connecting elements employed.

In these views, the numerals 5 and 6 indicate handles, from the inner edges of one of which a pair of ears 7 extend inwardly, a lug 8 from the other handle being disposed betweenthese cars which are spaced to this end, and both the lug and ears being formed with openings which align when the parts are in proper relative positions. The outer ends of the handles terminate in extended portions 9, eachprojecting between pairs of arms 10 formed'at the inner ends of jaw members 11.

One of t- 1e latter, similarly to the handles, has a pair ,of cars 12, and the other presents an inwardly extending lug 13, theseelements beingpivotally connected by means of a member hereinafter described, it being appreciated that suitable connecting elements, such as screws 14:, extend between the aligned openings of the parts 9, 1 0. Furthermore, while the ends or operating portions of the jaws may take any desiredform to provide, for example, a shearing or crushing edge or edges, it is preferred that. as shown they may terminate in spoon portions 15, havingedges which are sufficiently reduced to shear ligaments or tissues forcibly engaged therebetween.

.Now with a view to connecting the handles w 7 with each other, a pivot member is employed,

preferably which includes, as shown in Fig. 6, a pin portion 16 terminating in a head 17, from which an arm 18 extends and terminates in a U-shaped clip 19 of a configuration such that it may embrace one of the arms. The latter is preferably reduced as at 20 to provide a groove for the accommodation of this clip portion, and it is thus apparent that .with the pin extended through the I aligned openings of the ears of the lug, and the head lying immediately adjacent the out er surfate of one of the parts, as in Fig. 3, that the arm 18 may be swung to a position at which the clip will encircle partially the arm, and move withthe same. Thus, no accidental detachment of the parts is to be feared, but

these parts may be separated readily by simply forcing the clip from engagement with the arm and thereupon withdrawing the pin. The same construction isempl'oyed in connection with the pivot member for the aws, except that theparts at this point are preferably ona slightly smaller scale, it being noted that, similarly to the arm, one of the jaw members is grooved as at to accommodate the clip of the pivot member which retains these elements in applied position.

In order that the parts may normally lie in the position shown in Fig. 1, a spring member is preferably employed. lVhile such spring member may take numerous different forms, it will, according to the present inven tion, include conveniently a pair of spring strips 31 and 82, the upper end of the former terminating in a cup 33, and the upper end of the latter, in a spherical portion 34, thus providing a ball and socket connection. In order that these spring elements may be readily mounted, the inner ends of the arms carry elongated head portions 35 and the inner ends of the spring members are formed with corresponding openings 36. Thus, with the opening extending parallel to the head, the parts may be associated readily and thereafter, by simply swinging the spring members to extend parallel to the arms, they will be lorlzed against detachment therefrom. Also, to prevent any accidental shifting of the parts, projections 37 are carried upon the outer faces of the spring members, and at portions thereof which lie in intimate contact with the inner faces of the arms, these projections extending into recesses formed in the inner arm faces.

From the foregoing it will be appreciated that, among others, the several objects specifically afore referred to are achieved, it being noted that by virtue of the proportioning of the arms of the levers, providing the jaws and arms 5, 6, a surgeon with but minimum efi'ort may exert a maximum leverage, and that the parts may be readily and entirely separated for cleaning and sterilizing.

At this time it will also be observed that the aw members 11 are preferably curved at points beyond their pivot pin to extend outside of the plane in which the arms are disposed. By this expedient a surgeon may more readily manipulate the forceps, and 0p erate on the ligaments and tissues, etc.

It will be appreciated, finally, that numerous cl anges in construction, and rearrangement of the parts, might be resorted to without in the slightest departing from the spirit of the invention.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A device of the character described including a pair of jaws, a pivot pin for connecting said jaws, a rigid arm extending from such pin, and a-clip portion forming a continuation of said arm and engaging one of the jaws, the latter being formed with a groove for the reception of said clip.

2. A surgical instrument including, in combination, a pair of jaws, a pivot pin for connecting said jaws, a head forming a part of said pin, an arm extending from said head SIMON L. RUSKlN.
