Application March 18, 1937, Serial No. 131,705 In Sweden March 18, 1936 7 Claims.

The present invention relates to improvements in holders for surgical needles, the principal obj ect-of the-invention being to so 'construct'a holder that it may firmly grip needles of various forms and sizes.

A further object of the invention is to create a holder -for surgical needles by means of which theneedle by aslight'power will be firmly gripped in various positions between the jaws of the holder.

With these and other objects in view the invention'consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed-out in the claims.

An embodiment of the invention is illustrated in the accompanying drawing in which Fig. 1 shows aside-elevation of the holder in open position with certain parts removed. Figs. 2 and 3 show sections on the lines 11-11 and III-III respectively of Fig. 1. Fig. 4 is a cross-section of the jaws of the holder on the line IV--IV of Fig. '1. Fig. '5 shows a cross-section of the jaws in gripping position the needle being only indicated bydotted lines. Fig. '6 shows a plan View of one of these jaws, a needle also being indicated in this figure. Figure 7 is a diagrammatical View, showing, broadly, the manner of operation of the holder. Figs. 2 to 6 aredrawn on a larger scale than Fig. 1.

The holder is made in the shape of forceps, and =l represents one shank of the forceps carrying at the outer end a jaw 2 which is formed integrally with or is directly connected with the jaw I in the'usual'manner. This shank has a longitudinal recess 3 into which the extreme end of the other shank of the forceps projects. This latter shank by means of a pin 4 is pivoted to the first mentioned shank I and constitutes a double-armed lever the arm 5 of which projects into the recess 3 and is substantially shorter than the other arm 5 serving asa handle. The extremeend of the short arm 5 by means of a pin 1 is pivoted to a member or arm 8. The inner end of this arm is provided with a recess 9 extending in the longitudinal direction of the arm and engaging with a pin it fastened to the shank i. The arm or member 8 is pivotable about the pin l and is at the same time in a certain degree slidable along the shank l. formed as .a jaw H similar to the jaw 2 of the shank i. A concavo-convex plate or needle gripping member it is seated within the concave bearing surface 25 of the jaw l I and is connected to the latter by means of a pin I1 extending through a slot formed within the plate 16, whereby the The member 8 at the outer end is needle gripping member or plate may have a limited lateral movement'with respect to the jaw H. The longitudinal edges of the needle-gripping member extend past the longitudinal edges 'of the jaw H so that the member 15 may automatically adjust itself when gripping needles l9 of conical or tapering form as shown by Fig. 5. Thus also a needle of this form will be gripped quite as good as a needle the gripping portion of which has the same thickness throughout its 10 length.

As usual a spring I 5 is provided to move the shanks apart when they are released. The rather long shanks l, 6 are alsoin themselves of somewhat *springy character.

When the jaws are opened, as shown by Fig. l and by full lines in Fig. '7 the jaw ll of the pivotable and slidable member 8 is somewhat retracted i'n comparison with the other jaw '2. If the shanks are forced together as indicated by dotted lines in Fig. -'7, the jaw II will be pushed. forward a little as it swings towards the other jaw 2. By arranging the jaw 'l l on a particular slidable and pivotable member 8 the pivot pins '1 and ill of which are located on opposite sides of the .pivot pin "4 "between the shanks l, 6 of the holder, the gripping surfaces I3 receive such a movement that "the surfaces "i2, 13 will be practically parallel. Hereby the needle will bear on the surfaces I2, 13 in a favourable manner, i. e., not by means of "points but by means of surfaces. The needle will be gripped satisfactorily whether it is placed crosswise between the jaws as indicated by .Fig. 5 or lengthwise as indicated by Fig. 6. From the foregoing, it is quite obvious that a surgeons work will be greatly facilitated in the sewing up of cuts or other wounds by the use of .my holder, in that needlesof various sizes may betmore easily and'readily gripped'an'd firmly held at difierent angles by the surgeon. The 40 plate I 6 will automaticallyadjust itselfin a transverse dire'cti'o'n of the jaw H when gripping a needle so that needles having a tapering form as is indicated by the numeral IS in Figure 5 of the drawing may be firmly gripped and supported in a transverse direction across the holder by the opposite sides or edges of the jaw, whereas, if the member It were omitted or rigidly attached to the jaw H, only a biting contact at one point along the length of the needle would be effected, which would permit the needle to wabble within the holder. From Figure 5 of the drawing, it will be noted that this tapering needle is engaged at two points along its length by the opposite sides of the jaws in order to prevent the needle from havgripping plate It, needles of various shapes may be retained in a transverse direction between the jaws or extend in a longitudinal direction from the jaws as is illustrated in Figure 6 of the drawings. When pressure is applied to the handles I and 6, the jaw I! is given a sliding movement in a plane substantially parallel with that of the jaw 2, whereby, the needle will be properly seated within the jaws and upon the further application of pressure to the handles I and 6, the needle so seated will be firmly gripped between the jaws so as to prevent any wabbling movement whatsoever and permit the surgeon to more efiiciently perform the sewing operation.

I do not desire to restrict my invention to the embodiment above described with reference to the drawing, but the details thereof may be varied without departing from the spirit of the invention. For instance, in the drawing the distance between the pins 4, I is substantially shorter than the distance between the pins ill. The relation between these distances may also, for instance, be as l: 1. The pin ll] may be attached to the member 8 in which case the oblong hole or slot 9 is provided in the shank I. Also the jaw 2 may be provided with an adjustable channel-shaped needle-gripping member such as Hi.

What I claim as new is:

3. A holder for surgical needles comprising a pair of shanks pivoted together in the form of forceps, a jaw directly connected to one end of one of said shanks, a lever, said first mentioned shank having a longitudinally extending slot formed therein for receiving the inner portion of said lever, means pivotally and slidably connecting one end of said lever to said first mentioned shank within said slot, a jaw directly connected to the outer portion. of said lever, and the second of said shanks having an end pivotally connected to said lever between said jaw and said first mentioned pivotal connection of said lever.

4. A holder for surgical needles comprising a pair of shanks pivoted together in the form of forceps, a jaw formed on one end of one of said shanks, a lever, a jaw formed on one end of said lever, means pivotally and slidably connecting the opposite end of said lever to said first mentioned shank, the second of said shanks having an end pivotally connected to said lever between said jaw and said first mentioned pivotal connection of said lever and the distance between the pivot connecting said two shanks and the pivot connecting said lever and said second mentioned shank being substantially shorter than the distance between the pivot connecting said two shanks and the said pivotal means.
