Oneot the objects of thisinvention is to provide a needle to which the strand can be readily attached andvrhich, when in position, will be securely held. Y

' Anot'ier object is to provide a mean which is devoid of projecting parts so as to avoid eatchingot the needle din-1n its passage with the a tached strand. A

Fmther'OlJjeCtS will appear from the de tail description-taken in connection with the accompanying drawing, in which:

Figure 1 isan edge elevation of: the heel of a needle embodying this invention 5 Figure 2 is a side elevation; v Figure 3 is a similar view showing needle partially threaded;

Figure l is V a similar view needle completely threaded; Figure 5 is a view similar to Figure 2, but

the

' showing the showing another embodiment-oi this inven- Figure 6 is a similar View showing the needle threaded; and I Figure 7 is a section on line 7 7, Figures 2 and 5. e

Referring to the accompanying drawing, 1 designates the needle body which, as usual, comprises a shank having at one end a point and at its other end, a heel 2- to which the" tion, depending upon the uses for which the needle is intended. When uscd'as a surgical needle, it is usually oblong in section. The needle body or shank may furthermore be either straight or curved, as is usual in various types of needles.

The heel 2 is provided with an eye 3-which may taper towards the heel tip. This heel tip is split to form a pair of sections 4. having overlapping parts 5. Each of these overlap. ping parts tapers to an edge 6, and these parts are rounded and extend upwardly to provide horns. They may also be recessed as shown at 7 to receive the strand 8, as hereinafter described. The sections or legs l are arranged to form a second eye 9 which can taper away from the heel and towards the eye 3, while the heel between the eyes may further be longitudinally'recessed as shown at 10 to receive the strand.

in the practical operation of this the needle employed as a surgical needle) is passed thror and the adjacent side of the opposite leg or section 4. The other. end of the strand can then be similarly forced into the eye 9. when the strand is thus in position, as shown in Figure 4, the ends ot the strand willhave been forced into the eye 9 causing the legs to spread apart and as the heel, as well the pery condition, as usually the case in surgical sutures, for this strand will be wedged 1 into the wet ge-sha'ped portionot the eye,

and thus serve as an additional holding means. 'l fhen it is desired to disengage the strand from the needle, this can be accomplished byreversing the operation, as the strand ends can again be removed fromthe eye 9 by forcing the strandinto the wedge shaped recesses betwecnthe horn of one leg and the adjoining face or the other leg.

In Figures 5 and 6, the eye 3 has been omitted, but the"construction is otherwise like that shown in'l igures l to t inclusive. The application of the strand to this needle will be obvious, and it willbenoted that when the strand is in position, the hight of it'will be securely clamped between the overlapping legs, while the horns 5 again act as guards to prevent accidental disengagen'ient of the strand from the eye, until it is desired to remove it, when the unthreading can be accomplished in the same manner as previously described.

It Will thus be seen that the invention accomplishes its objects. The needleis simple in construction but effective in its action. It can be readilythreaded and unthreaded, so that the tedious operations usually required for threading are avoided. At the same time,

the strand is securely held in position so as needle, the strand 8 (which may be a suture when I the eye 3, and orient. the; ends oi? thostrzuid is then passed into the eye 5} as shown in Figured by forcing it into the. tapering recess formed between the edge 6 to prevent accidental disengagement. Moreover all projecting parts are avoided, so that tearing and catching during the passage of the needle areentirely avoided. This needle is especially adapted as a surgical needl'eior the reason that the threading operations can be accomplished with great facility, thereby reducing the time of the operation which is extremely important. Furthermore tearing and lacerating of the wound by passage of the needle is really avoided.

It is obvious that various changes may be made in details of construction without de-' parting from the spirit of this invention; it

is, therefore, to be understood that this in first eye being tapered toward said second eye and having resilient portions, whereby a strand passing through both eyes when pulled through said second eye will be clamped in said first eye.

3. A needle, the heel of which is resilient and divided to provide resilient sections forming together a narrow expansible and" contractible eye, he, terminals of said sections being formed to spread apart sufiiciently to permit entrance into said eye of a strand, said sections being adapted to clamp the strand so inserted in said eye, and theneedle having a second eye tapering toward said first eye andadapted to bind the strand therein.

4. A surgical needle provided with an eye, said eye having resilient side portions, a second eye between said first eye and the point of the needle and tapering toward said.

first eyc, said second eye forming awedging socket and said first eye forming a clamping socket, adapted to hold the strand.

5. A needle having a narrow eye open at its heel end and having resilient side portions spaced closely enough together to clamp a strandtherewithin, and a second eye between said first eye and the point of the needle.

6. A needle having a narrow eye at its heel, said eye tapering'toward the point of the needle, and "having resilient portions adapted to clamp a strand therein, and a second eye between said first eye and the point of the needle, said needle having thread receiving grooves extending between said eygs.

its heel end and having resilient side portions spaced closely enouglrtogether to clamp av strand therewithin, and a second eye between said first eye and the point of the needle, said needle having thread receiving grooves extending between said eyes.

, 8. A needle, the heel of which is resilient and divided to provide resilient sections forming together a narrow expansible and contraetible eye, the terminals ots a id sections being formed to spread apart sufficiently to permit entrance into said eye of a strand, said sections being adapted to clamp the strand so inserted in said eye, andthe needle having a second eye tapering toward said first eye and adaptedto bind the strand therein, said needle having thread receiving grooves extending between said eyes.

9. A surgical needle provided with an eye, said eye having resilient side portions, a second eye between said first eye and the point of the needle and tapering toward said. first eye, said second eye forming a wedging socket and said first eye forming a clamping socket adapted to hold the, strand, said needle having thread receiving grooves extending between said eyes. 7 i

10. A needle having a narrow eye at its heel, said eye tapering toward the pointof the needle, and having resilient portions! adapted to clamp a: strand therein, and a second eyebetween said first eye and the point of the needle, said needle having thread receiving grooves extending 'between said eyes, and from said first mentioned eye, along the heel. of the needle, whereby the needle and thread will present a substantially smooth exterior.

In testimony whereof I ai'fix my signature this 23rd day of December, 1921.
