This `invention relatesr to improvements in surgical needles, and more especially to such a needle particularly adapted for sewing or suturing in connection with surgical operations.

@ne of the features of the invention is the provision ot means permitting the quick attachment of the needle of the `facia, fibre, thread, string, or other material used in connection with the sewing. is so constructed that, not only can the end of the acia, fibre, or thread be quickly attached thereto, but such end is ,securely gripped and held by the needle so that likelihood of the needle pulling loose trom the thread is reduced to a minimum. The attachment of the end of the thread to the needle is also eitected with little or no injury to the end of the thread, thus also diminishing the possibilit of the thread pulling loose from the nee le.

Other features and advantages of my invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawings Figure 1 is ya view in side elevation, Fig. 2 is a view in top plan, Fig. 3 is a horizontal sectional view, Fig. et is a similar view, showing the jaw of the needle open, and Fig. 5 is a view similar to Fig. 3 showing a modified form. As shown in the drawings, 10 indicates in general the point of the needle, which may be curved, as shown, or in any other form. The shank'of the needle isv somewhat enlarged at 11 in theusual way and the end of the needle, instead of being provided with the usual eye, has a pivoted jaw 12 mounted on a square pivot 13. The pivotal mounting is accomplished by means of a keyhole-shaped aperture 14 ,in the jaw 12 so that when the jaw is pushed forward as shown in Fig. t it may be opened.k When it is slid back as shown in Fig. 3 so that the pivot 13 moves into the squared part of the keyhole-shaped aperture the j aw is held locked in its closed position.

The stationary end of the shank as indicated by 15 is grooved or hollowed out as indicated by 16 and the inner face of' the jaw 12 is likewise hollowed or grooved as indicated by 17. kThe stationary part 15 is also preferably provided with some teeth,

The needle.

Claws or prongs as,A indicated by 18, preter- .fably 4curved `forwardly'and the jaw 12' has similar teeth as indicated by 19. I have here shown the stationary jaw 15 as provided with two rows of such teeth, two in eachl row, and themovable jaw 12 has one row of two teeth, the teeth on the movable jaw adapted to lie between those on the stationary jaw when the jaw is closed.y

20 indicates the end of the facia, gut, string, fibre or other material used in connection with the sewing y In the operation of the needle, the jaw 12 is open kas shown ,in Fig. 4, the end of the string or tacia 2O is hooked over the teeth 18, the jaw 12 closed, and slid backwardly as shown in Fig. 3 to look it. The teeth 19 and 20 will then be iirmly engaged in the end of the thread 2O and hold the same `irmly to the needle. f

In Fig. 5 I have shown a `slightly modiiied form in which the teeth ,in the movable jaw 12 are dispensed with andlonger teeth 18a are provided in the stationary jaw 15u.

rIhe operation of this device is similar.-

That is, the end of the thread is hooked over the teeth 18at and the movable jaw 12a closed to hold it on the teeth.

The invention is especially valuable in sewing with fibres, facia and the like which are diiiicult to thread through the eye ot a needle. By the use of my invention, also, the double thickness of the thread where threaded through the eye Iis ydispensed with.

It will be seen that the end of my needle with `the jaw when closed is no larger in diameter than the regular shank 11 of the needle. Consequently, in sewing, an unnecessarily large hole is not made as in the case where a double thickness of thread must be pulled through each hole.

While I have shown and described eertain embodiments of my Iinvention, it is to be understood that it is capable of many modications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope ot the vinvention disclosed Iin the appended claims, in which it is my intention to claim all novelty in my invention as broadly as possible ,in view ot the prior art.

VVhatI claim as new, and desire to secure by Letters Patent, is:

1. A needle having a pointed end with a thickened shank including a stationary part with :a jaw pi-voted thereto., :said ,j aw adapted to be closed against the `stationary part to grip the end of a thread therebetween, and

means operated by movement of the vjaw for locking the kjawin its closedposition.

2. A needle having 'a pointed end with a thickened shank including a stationary ,part- With a aw pivoted thereto, said aWV adapted to be Closed against the stationary part :to grip the end of a thread therebetween, and `means for locking the jaw in its closed position, said fmeans including square 'pivot on the stationary part and a keyhole-shaped slot inthe jaw embracing said-pivot.

`3. A needle having `a pointed end with a .thickened shank including a stationary part
