SURGICAL NEEDLE.

T0 or whom it may concern:

Be it known that I, THOMAS CLAY En- WARDS, a citizen of the United States, residing at Salinas city, in the county of Monterey and State of California, have invented a new and useful Surgical Needle, of which the following is a specification.

This invention relates to surgical needles, and has for its principal object to provide an improved form of needle in which the end of a suture may be firmly clamped, thus avoiding the necessity of sewing by a double strand, and reducing the size of the openings formed in the tissues during the sewing operation.

A further object of the invention is to provide a needle which may be quickly threaded, and in which no portion of the suture will project beyond the diameter of the needle.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the ad vantages of the invention.

In the accompanying drawings :Figure 1 is a perspective view of a surgical needle constructed in accordance with the invention. Fig. 2 is an elevation of one side of the head of the needle on an enlarged scale. Fig. 3 is a similar view of the head of the needle looking from the side opposite that shown in Fig. 2. Figs. 4 and 5 illustrate, respectively, the two sides of the needle at right angle to the parts shown in Figs. 2 and 3. Fig. 6 is a transverse section on the line 6-6 of Fig. 3. Fig. 7 is a similar view on the line 77 of Fig. 3. Fig. 8 is a sectional elevation of the head of a needle of slightly modified construction. Fig. 9 is a plan view of the same. Fig. 10 is a plan view illustrating a further modification. Fig. 11 illustrates a still further modification of the invention. Figs. 12 and 13 are sectional views illustrating further modified forms.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawm s.

The needle 10 may be made of any size and contour, depending on the work or operation Specification of Letters Patent.

' performed, and in the preferred construction j the head of the needle is provided with a groove 15 in which the thread is concealed, i no portion of the thread projecting beyond the dilneter of the needle.

Near the head of the needle two eyes 16 and 17 are bored, and the ends of the eyes are connected by a groove 18 formed in that face of the needle opposite the groove 15. I11 the preferred construction the eyes 16 and 17 are placed at angles of ninety degrees from each other, and the groove 18 which connects said eyes is therefore inclined or helical.

In threading the needle, the suture is first passed through the eye 16 and then through the eye 17, the end being drawn through far enough to permit the operator to grasp and hold it while the suture is drawn tight and embedded in the grooves 18 and 18. The threading end of the suture is then severed close to that end of the eye 17 from which it emerges, so that no portion shall project beyond the diameter of the needle. The edges of the eyes serve as a binding means which will firmly grip and hold the suture, so that it is unnecessary to form a knot in the end of the same. In many cases the two eyes may be formed substantially parallel with each other, as shown, for instance in Fig. 8.

Fig. 9 illustrates a construction in which the eye 17 nearest the head of the needle is slightly ovate in form, tapering to a rather sharp contracted end which will firmly grip the suture.

In some cases, as illustrated in Figs. 10 and 11, the end of the needle may be split, the split portion extending from the head of the needle to the nearest eye, as shown in Fig. 10, or the slit may terminate short of the eye as shown in Fig. 11.

In order to avoid the formation of the slot, the eye nearest the head may be arranged as shown in Fig. 12. In this case the eye 17 is bored. from the end of the needle in a plane oblique to the axis of said needle, and this eye is connected with the eye 16 by a short groove.

As a modification of the construction shown. in Fig. 12, the second eye may be arranged oblique to the axis of the needle, as shown for instance at 16 in Fig. 13, thereby forming a rather sharp edge between the connected ends of the eyes.

In both the constructions shown in Figs. 12 and 13 the opening 17 is used, the opening 17 of the needle shown in Fig. 12 being arranged at a right angle to the opening 16 and in Fig. 13 the opening 17 is disposed at a right angle to the opening 16*. In both cases the helical groove is used to connect the adj acent ends of the openings or eyes. In all cases the needle is provided with a plurality of eyes so arranged. that the sharp edges at the ends of such eyes Will firmly grip and hold the suture, avoiding the necessity of forming a knot at the end of the suture as ordinarily practiced in single thread surgical needles.

I claim:

1. A single thread surgical needle having a pair of threading eyes crossing the axis of the needle at an angle to each other.

2. A single thread surgical needle having a palr of threadlng eyes crossing the axis of the THOMAS CLAY EDWARDS.
