Specification of Letters Patent.
Iatented Apr. 11, 1911.
Application filed April 9, 1908. Serial No. 426,110.
1 '0 all whom 'it may concern:
lie it known that l. (LliYl-IHANI) (i. :DAYIS. citizen of the United States. residing at Ma'nistee. in the county of Manistec and State of \lichigan, have invented certain new and useful Improvements in Surgical Needles. of which the following is a specification.
The present invention relates in general to surgery and more particularly to an improved surgical needle enil'iodying novel .meaus for sterilizing the thread employed in connection therewith.
The invention-further contemplates means for supplying the needle with thread from a rollor bobbin. thereby enabling several yards of thread 'to be employed and a number of stitches to be taken witlibut the necessity of rethreadiug the needle.
A further objectof the invention is the provision of a needle of this-character which Is simple and inexpensive in its construction and will operate 111 an effective manner to accon'lplish the desired result.
For a full understa-mling of the invention and the merits thereof and also to acquire a knowledge of the detailsof construction and the means for e'll'ecting the result, referonce is to be had to the following description and accompanying drawings, in which:
Figure 1 is a perspective view of. a surgi cal needle embodying the invention. Fig. 2
is a longitudinal sectional view through the' same. Fig. 3 is a similar view of the handle; Fig. 41. is a detached perspective view of the receptacle arranged within the handle and adapted to,c0ntan1 an antiseptic solution for sterilizing the thread. Fig. 5 IS an enlarged sectional view through the needle'engaglng clamp.
' Corresponding and like parts are referred to in the following description and. indicated reference clniractcrs.
I Referriug lo the drawing, the numeral 1 designates the handle which has a hollow 0rtubular tornnition and is normally closed-by means of a cap 2. This cap 1s approxlmately conical in shape and is provided at, its base with a flange 2 which is threaded upon the mouth of the handle 1. Jaws 4 are'iocated to force th'ejaws inwardly so as to engage the shank of a needle placed between the same. l'lowever, by turning the clamping ring inwardly the jaws will be permitted to spread apart and release the needle. It will thus be apparent that various sizes and forms of be required.
A. receptacle 7 fits snugly within the handle 1 so as to be completely inclosed therein and protected from injury thereby, the said receptacle being designed to contain an antiseptic solution. A ball of thread 8 is placed within the receptacle 7 and the end of the thread is drawn through an opening in the stopper 9 of the receptacle, the said stopper servingto prevent leakage of the antiseptic solution from the receptacle and also acting to expel all surplus moisture from .the thread. After 'being drawn through the stopper S.) the thread is passed through an opening 10 in the'cap 2. extends along the needle 5 and is threaded through the eye 5 of theneedle. It will thus be obvious that the thread held within the-re-' cep tacle sterilized by the antiseptic solution and that the thread may be drawn from the receptacle as required for use in connection with the needle. I
In using the device the needle is pushed through the incision and carries the thread with it, the operator taking hold of the end needles may be applied to the cap 2 as may of'th e thread and pulling back the needle so as to leave the thread in the wound as'a stitch to be tied after the assistant has cut it. The needle is then ready for another stitch without the necessity of rethreading the same and the thread" which is supplied -to the needle is completely sterilized by the antiseptic solution within the receptacle. it will be obvious that should it be found do sirable the-thread may be 'wound 'upon a bobbin previous to being placed in the receptacle, and that any suitable form of thread may be employed, either silk, linen,- or catgut.
The peculiar construction of the surgical instrument above described has certain ad vantages which are pecidiarly due to the. shape .of the cap and the peculiar relation which the cap has to the receptacle contained within 'the handle. The handle is imporforate or solid and is only open at one end, this end being closed by the conical cap and by the stopper, to the internal receptacle. Hence, the thread is entirely contoo - projects through the stopper 5), but not.
through the cap, and hence is entirely protected by the cap. When it is desired to use. the device, the cap can he unscrewed, the thread passed through the hole in the cap, 5 and threaded into the needle. Under orglinary cireun'istances, however, the thread is protected. The interior receptacle has practice ily the same dimensions as the ham dle, though preferably it. projects somewhat 0 above the handle, and thus the conical cap contacts with the receptacle 7 and holds it in place so that. the receptacle cannot shift. as it. would if the receptacle were slightly smaller than the. handle. Furthermore, the a cap 2 acts to hold the stopper 9 in plate within the inner .reeeptael and prevents the stopper rising so as to come out. of the end of the receptacle As a consequence, the opening through the stopper 9 for the passage ol the thread, may he made relatively sn'ialhso as to tightly til the thread. Thus leakage prevented, and atv the same time the frictional engagement oi the llli"tltl with the stopper will not act to draw the stopper out of the month of the receptacle, the stopper being held in place. by the inwardly inclined walls of the cap. The conical 'l'ornia- -tioneot. the cap has likewise this ad vantage, that it permits the cap to be turned rela tively to the stopper so that the thread opening in the cap stopper shall not exactly aline, whereas if the cap were not conical but extended directly across the end of the handle so as to contact with the stopper and hold it in place, a very slight diflerence in registry between the thread hole in the cap and the thread hole in the stopper would tend to kink the thread. This would not only tend to prevent. the withdrawal of the thread, but would also act to cut it. The inner receptacle 7 extending as it; does above or even with the month of the handle 1, and being closed by the stopper 9, there is little chance of leakage past the screwthreaded tlange E2. The handle being solid, this is the only point where leakage can occur.
llavig g thus described the invention, what is tilai as new is:
A snrgrfial instrument consisting of :1. cylindt'leal, lulmlar. nnpert'orate handle open at. one end.a cylindrical receptacle adapted to snugly (it within the handle with its upper edge slightly rn'ojeet ing beyond the open end of the handle, a stopper closing the monthot the receptacle and having an open ing' extending therethrongh for the passage ol the thread, a hollow conical cap having an annnia r interiorly screw-threaded flange at its base engaging the end of the hollow. handle and elosing'the same, said cap contatting; with the. slightly projecting edge of the receptacle and holding the receptacle and stopper securely in place against movement. said'cap being" perforated for the 'pas sage ol the thread, and a. clamp forming the end of the cap and adapted to engage a needle.
