NEEDLE CROSS REFERENCE TO RELATED APPLICATION This application is a continuation-in-part of copending application Ser. No. 277,944, filed Aug. 4, 1972, and entitled NEEDLE, now US. Pat. No. 3,754,693.
BACKGROUND OF THE INVENTION The present invention relates to needles.
In particular, the present invention relates to that type of needle which is adapted to pierce through the work, after which a loop is pulled from the needle, and the latter is extracted from the work and again passed through the work and through the previously extracted loop so as to form in this way the desired stitches.
Conventional needles of this type are incapable of maintaining the filamentary material out of engagement with the work so that the filamentary material necessarily rubs against the work during the formation of the stitches. This is a highly undesirable drawback particularly in the case of needles used during surgical operations for the purpose of applying sutures.
Furthermore, with the conventional needles of the above type it is difficult to grasp the filamentary material in order to pull it from the needle when forming a loop.
In addition, at the end of the operation when it is desired to cut the filamentary material it is necessary to use a separate tool such as a suitable scissors for this purpose. This latter requirement also is a considerable inconvenience since it requires the use of a separate implement. This requirement results in additional time involved in manipulating the additional implement.
SUMMARY OFTHE INVENTION It is accordingly the primary object of the present invention to provide a needle which will avoid the above drawbacks.
In particular, it is an object of the present invention to provide a needle which is of an exceedingly simple, robust construction having an exterior smooth surface which will injure the work to a minimum extent while at the same time maintaining the filamentary material out of contact with the work while the needle pierces through the work.
Furthermore, it is an object of the present invention to provide a needle of the above type which greatly facilitates formation of a loop from the filamentary material. 1
In addition, it is an object of the present invention to provide a needle of this type which enables the filamen tary material to be cut without requiring the use of an additional implement such as a scissors.
According to the invention, the needle includes an elongated body formed at one end with a sharp pointed tip facilitating piercing of the needle through the work. This elongated body has a longitudinal central axis contained in a plane on opposite sides of which the body is formed with a pair of longitudinal bores for receiving the filamentary material. At the region of the tip the body is formed with a transverse notch communicating with front ends'of the bores and forming an open eye so that the filamentary material may extend forwardly along the interior of one of the bores, across the open eye, and then rearwardly along the interior of the other of the bores. In this way, when the needle pierces through the work the filamentary material will not engage in the work while at the same time a loop can be pulled from the open eye of the body.

FIG. 9 is a transverse section of'the needle of FIG. 8 taken along line 99 of FIG. 8 in the direction of the arrows; and
FIG. 10 shows how the structure of FIG. 9 may be rotated in one direction for cutting the filamentary mate rial.
DESCRIPTION OF PREFERRED EMBODIMENTS Referring to the drawings, the needle of the invention is in the form of an elongated body 20 made of any suitable metal, for example, and having a circular crosssection as is apparent from FIGS. 5, 9 and 10. The elongated body 20 is of a constant diameter all the way up to the region of its front tapered end portion 22 which terminates in a sharp, pointed tip 24 capable of penetrating into the workmaterial'.
The elongated body 20 has a longitudinal central axis contained in acentral longitudinal plane which is the plane in which the sectional views of FIGS. 6 and 7 are taken. On opposite sides of this central plane theelongated body 20 is formed with a pair of longitudinal bores 26 and 28 which extend parallel to the axis of the body 20. These bores extend all the way to the rearend ing with the front ends of the bores 26 and 28, so that the filamentary material can extend forwardly along one of the bores 26 and 28, then across the open eye 30 and rearwardly along the other of the bores 26 and 28. The filamentary material is shown in this condition in phantom lines in FIG. 4 with the filamentary material shown in phantom lines extending across the open eye 30 in FIG. 3.
One of the bores 26 and 28, the bore 26 in the illustrated example, communicates with the exterior of the needle through a longitudinally extending opening 32 which is formed through the wall of the body beside the bore 26 so that the latter is accessible from the exterior through the longitudinal opening 32. It will be noted that this opening 32 extends along the entire length of the bore 26. The opening 32 has an upper edge 34 and a lower edge 36 between which the opening 32 extends, and these edges have sharp portions 38 and 40, respectively, as shown in FIG. 2, forming cutting regions which are capable of cutting the filamentary material 42.
In addition to being formed with the transverse notch which defines the open eye 30, the body 20 is formed with a pair of additional notches 44 and 46 respectively situated forwardly and rearwardly of the open eye in the plane which contains the central longitudinal axis of the body 20. These additional notches 44 and 46 communicate with the open eye 30. The body 20 is also formed with an intermediate curved notch portion 48 extending deeper than the transverse notch 30 and communicating therewith, this intermediate notch 48 connecting the pair of notches 44 and 46, so that all of this notch structure 44, 46, 48 has a continuous inner surface 50 which is curved in the manner shown most clearly in FIGS. 3, 6, and 7.
With the above-described needle of the invention, it is possible to thread the filamentary material 42 forwardly along one of the bores 26 and 28, then across the open eye 30 and rearwardly along the other of the bores. The fact the bore 26 is open at one side facilitates the handling of the filamentary material 42. This filamentary material may be suitable suture material where the needle of the invention is used for surgical purposes. With the filamentary material threaded in this way through the needle, the latter may be pierced through the work, and then a suitable hook 52 (FIGS. 6 and 7) may be applied to the front end of the filamentary material to pull a loop from the needle. This hook 52 may be inserted either into the notch 46 to engage behind the filamentary material in the open eye 30, as shown in FIG. 6, or it may be introduced through the front notch 44 in the manner shown in FIG. 7. In this way, it is extremely convenient to pull a loop of the filamentary material from the needle.
In addition, when it is desired to cut the filamentary material 42, it may be pulled from the bore 26 up to the region of the cutting edges 38 and 40, as illustrated in FIG. 8. Then the body 20 may be turned in either direction as shown by the double-headed arrows in FIGS. 8 and 9. For example, if the body 20 is turned in a clockwise direction, as shown by the arrow in FIG. 10, the upper cutting edge 38 will cut the filamentary material 42. If the body is turned in the opposite direction, the lower cutting edge will cut the material.
In this way an extremely robust and simple needle is provided with a smooth exterior surface. The filamentary material is housed within the needle so that it will not engage the work while the needle passes therethrough. At the same time it is a convenient matter to form a loop in either the manner shown in FIG. 7 or in the manner shown in FIG. 6 and of course it is possible to cut the filamentary material with either of the edges 38 or 40 without requiring the use of an additional implement for this purpose.
