NEED LE AND METHOD OF MAKING THE SAME.
Application filed December 2, 1925. Serial No. 72,704.
The following is a descriptionof aneedle My invention will best be understood by and methods of making the same embodying reference to the accompanying drawings, in 55 my invention in the form and manner at which I have illustrated the preferred form present preferred by me; but it will be unof my invention and methods of making the derstood that various modifications and same, and in which Fig. 1 shows in elevation changes may be made without departing a so-called half-curved needle of the confrom the spirit of my invention and with ventional type; Fig. 2 shows such a needle 60 out exceeding the scope of my claims. with a fin formed on the convex side of the In my application Serial No. 55,268, filed curved portion; Fig. 3 is an enlarged cross- September 9, 1925, I disclosed a straight sectional view on the line 3-3 of Fig. 2; needle provided with three cutting edges, and Fig. 4 shows in elevation another type and particularly adapted for use in the art of needle embodying my invention. 66 of surgery. My present invention relates Like reference characters indicate like to curved needles suitable for similar use parts throughout the drawings.
and provided with a single cutting edge on Referring to the drawings: 1 indicates the the convex side of such needle. body of a needle which may have formed in In surgical operations much elfort is reits shank end an eye or other suture-carry- 70 quired to force a needle of the usual type ing means (not shown). 2 is the point of through certain tissues, such .as the skin upon the needle, which may be of any convenient some portions of the body, the scalp and shape and which may be formed in the antendons. In certain classes of surgical work nealed blank by any suitable method, as by a half-curved or full-curved needle may be grinding or swaging; 8 isa fin formed along 75 more easily manipulated than a straight a portion of the curved part of the needle in needle; and the principal object of my presany suitable manner, as by pressing, stampent invention is to provide a needle all or 111g or swaging one side of the said needle, some portion of which is curved, and to producing recesses 4; and 4? and forcing the form on the convex side of a portion of metal therefrom into the fin. This operation 80 such curve a projecting fin which is finished may be carried out either before or after to a keen cutting edge. Such a needle may the needle is curved, and while the needle be more readily passed through resistant is still in its annealed state. After the fin tissues than the conventional curved needle has been formed and the needle has been which is circular in. cross section. So far curved, it is hardened, tempered and pol- 85 as I am aware, it is new in this art to provide ished, the point being re-groun'd, if necesa curved needle so constructed and arranged sary. The fin is then given a keen cutting as topermit of forming on the convex side edge throughout its length, as by grinding of the curve a keen cutting edge. or other suitable process.
Surgical needles are usually of such small In use, the fine point of a needle readily diameter that attempts to hollow-grind them enters tough and resistant tissue; but as the to form a cutting edge would present almost diameter increases along the taper, the efinsuperable obstacles. By my invention it is fort required to perforate such tissue propossible, with simple and practicable mangresslvely increases. By my invention, the ufacturing methods, to form on the convex iine sharp needle point also readily pene- 95 side of the curved needle a cutting edge so trates the tissue, but, before the diameter of keen that but slight effort is necessary to the needle has materially increased, the cutcause the needle to cut its way through thick ting blade becomes operative, and thereafter and resistant tissue. In a needle which is serves as a keen knife to easily cut a path full curved or partly curved, it is desirable for the needle body and suture. With the 100 that the cutting shall be in a direction away ordinary needle, on the contrary, the tissue from the lips of the wound, leaving a is not cut, but is necessarily forced or comsmooth, uncut perforation adjacent such lips. pressed together to form the perforation. The possibility of the stitches tearing out The trauma resulting from the formation by reason of the tension applied to the suture through tissue of a clean-cut aseptic pasis thereby reduced. sage due to the action of a needle embodying my invention is less than that caused by the bruising etl ect of the ordinary noncutting needle.
hat I claim as new and desire to secure by Letters Patent of the United States is:
1. A needle having a curved portion and a cutting blade on the convex side oi such curve.
2. A needle having a curved portion and a radial cutting blade projecting from the convex side thereof.
3. A curved needle provided with a fin radially projecting from the convex side thereot and comprising a cut ing blade.
i. A curved needle provided with an arcuate cutting blade projecting radially from the convex side thereof and beyond the body of said needle.
5. A needle having a curved portion the convex side of Which is provided With a radial cutting blade projecting beyond the body of the needle.
6. A. curved needle rovided with a point and a radially projecting cutting fin extending along said curve and terminating short 25 of said point.
