resistance or obstruction to its smooth passage through tissues or membranes. Although this unitary needle and suture is very successful and approved by surgeons it is, nevertheless, somewhat expensive as when once a needle has been employed it cannot be used again but must be discarded as there is no means of replacing the old suture by a new one; consequently, a fresh needle with its attached suture has to be employed for every operation however small. 7
The object of the present invention is to remove the above disadvantage and provide a form of suture and mode of securing such to a needle whereby sutures can be attached to their needles and removed therefrom at will while at the same time providing a junction which offers little or no resistance or obstruction to its smooth penetration through-tissues or membranes or, in other words, affords sewing facilities substantially equal to those of eyeless nee attached suture.
The invention consists in providing sutures with eyes adapted to be engaged-or temporarily secured in needle eyes. By suture eyes? is meant, not only holes or apertures extending" .from side to side but is intended to include op- "po'sed sockets or recesses separated from one another by a thin web or partition. According to the invention sutures are formed each with an eyed end or an eyed link or ferrule permanentlyse cured to the suture end and adapted to be engaged or temporarilyinterlocked in the eye of a self-threading or spring-eyed needle of known form per se.
The invention comprises an improved mode of securing a suture to a self-threading or springeyed needle, which consists in detachably engaging the eyed suture end between the spring shoulders of the needle so that the shoulders meet l or close in the eye aperture or recess, in contradistinction to locating the suture in the eye of the needle below the spring shoulders.
The invention also consists in various methods of manufacturing suture eyes or eyed links or ferrules, for fixing to one end of the suture, on the dles with permanently November 30, 1931 one hand, and detachably securing to a selfthreading or spring-eyed needleon'the other.
The links are preferably of metal'but may be of any suitable material such for example as one of the appropriate mouldablecompositions.
The eyes (holes or sockets) "may be circular, rectangular, triangular or any other desired shape. H

I
Incarrying the'invention intoeifect according to one convenient mode for the production of eyed links or ferrules for sutures, as illustrated in Figures 1 2 and 3, a suitable length of metal tube 1 of appropriatediameter and preferably of silver or non-corrosive metaL is fiattenedlsee. Figure 4) at points separated by double the length required for a link or ferrule. The flat tened portion 2 is bored or stamped to form eyes at two places as indicated by the arrows 3 and is then severed on the lines 4 and 5, the severance at 4 being a straight out while at 5 the tube may be sheared so as to give each portion a rounded or radiused end contour substantially parallel with the outer semicircular portion of the eye hole, as seen in Figure 1.-'
The link or ferrule thus formed comprises a sleeve or tubular socket 1a terminating in a flattened portion having an eye 36: which, as will be seen, is located as close to the rounded end 5a as is consistent with strength. The flattening process in the region 2 (see Figure 4) is also adapted to afford smooth curving shoulders 6 so as to offer no obstruction to the passage through a tissue or membrane in the sewing direction.
The suture is introduced into the socket 1a and secured by an indented annulus 7 or by crimping or otherwise deforming the socket in such a way as to pinch the suture 8 without unduly roughening the surface of the socket.
In carrying the invention into effect according to another mode, suitable tubes (such as seen in Figure '7) are cut to the required length and tubular or solid pieces (see Figure 6) having a barrel portion lb and a flattened portion 2a are formed with eye holes 3a., The barrel portion may be formed with a roughened or serrated area 9 and with shoulder at 6 as already described in reference to Figure 2. The unit shown in Figure 6 is introduced into the end of a tube 1a (Figure 7) and a junction is made by crimping or clamping pressure or by spinning down the end of the tube as at 10 upon the roughened part 9 of the barrel la. The suture is introduced into the open end of the tube 10; and crimped or provided with an indented annulus as at 7.
of the tube as at 11 thereon.
" In carrying the invention into effect according to another convenient mode, asplit tubular socket 1b (as seen in Figur'e 9) is formed and closed upon the suture in any suitable'manner as, for example, substantially according to the mode described in British Letters Patent No. 288,425 with reference to eyeless nedlesand is also provided with a flattened pieceor extension 20. which is provided with an eye hole 3a. In this form, as
in those previously described, it is preferred to make the tubular portion with a curved shoulder 6 and in this connection it is pointed out that inthevform shown in Figure 1 the shoulder may be. '(if annular form instead of upon each side as shown in Figure 2.
It will be understood that the customary'way of introducing a suture into a self-threading or spring-eyed needle (as shown in Figure 10 or 11) is to lay the running end of the suture across the V-shaped end 12 of the needle and force it between the spring-pressed shoulders 13 into the eye 14 of the needle. It will be understood that according to this mode, when the needle is threaded .there is a double thickness of suture or thread at the needle eye in the ordinary way.
The improved suture is attached to the needle, according to the invention, by introducing the rounded edge of the flattened portion 2a. of the ferrule or eyed link into the V-shaped cavity 12 and pressing downwards between the spring i shoulders so that the latter snap into the eye 3a ofthe ferrule, in which position it will be seen that the shoulders meettogether orclose in the seen in Figure 12) and pressing downwardly upon.
the ferrule so that the upper edge of the aperture 3a acts upon the V-shaped incline of the i,eeo,117
shoulders and allows the eye to slip freely away downwards and be released.
In any of the forms of the invention above described instead of making the suture or link eyes as throughway apertures or holes they may be formed as shown in Figure 13 in which a pair of opposed or back to back sockets or recesses 3b are stamped or impressed in the link. These sockets or recesses are engaged in the needle between the shoulders 13 in the same way as the throughway eyes are, with the exception, that the shoulders 13 will not meet but will be separated by and close upon the web or partition So.
If desired, instead of attaching the sutures to needles in the manner indicated, a pair of forceps or other instrument may be utilized in the eye of the needle to open the spring shoulders so that the eyed ferrule is introduced or engaged between the shoulders after which the forceps or instrument is withdrawn.
The outside diameter of the ferrules or links as described above, may be made less than that of the needle, particularly with regard to the larger sizes of needle, but ferrules of larger diameters than the needles may be employed as the sloping shoulders of the ferrule afford a lead or smooth entrance in passing through a membrane or tissue.
The sutures employed according to the invention may be of catgut, silk, linen thread, silkworm gut, Japanese gut or the like. Furthermore, silver wire or other metal sutures may be employed in which case the end of a wire'may be clamped in a ferrule of any of the forms above described or, alternatively, the end of the wire itself may be provided with an eye hole or sockets as, for example, by flattening the wire at the end and rounding it, if desired, and piercing or drilling an eye hole or stamping eye sockets or recesses of appropriate diameter, thus forming an integral eyeleted suture. I
The invention may be supplied to the trade theform of eyed sutures or sutures having eyed ferrules or links secured thereto, or eyed ferrules or wire loops may be supplied alone for attachment bythe surgeon or operator to sutures as required. For this purpose the sutures are inserted in the tubular sockets of the ferrules which are clamped upon the suture by the use of a pair of pliers or other appliance which may be specially formed with a pair of semicircular dies for the purpose, or may be otherwise provided with dies for crimping or pressing the ferrulev on to the suture end. Where a link as shown in Figure 9 is employed pliers having jaws suitable for closing the lipsof' the slot or slit upon the suture in the ferrule, may be employed.
It is pointed out that self threading needles (see Figures l0and 11) having the shoulders and V,notch proportions as illustrated are recommended for use in connection with eyed ferrules as shown in the other figures but where needles having other notches and shoulders are to be employed changes in dimensions should be made in the eyed ferrule to suit.
It will be. appreciated that the invention is primarily concerned with surgical needles but sutures or sewing threads for other purposes (where the features of the invention would be advantageous and suitable) may be provided with eyed links or eyed ends for attaching to spring-eyed needles according to the invention, if desired.
