NEEDLE- OLDER. 1

l *x'aimi i To all "who mitt may concern: Be, it known that I, EDWIN a citizen of the United States. residing at St. Louis; ll Iissouri, have invented a certain new; and useful Improvement in Needle rial #776,659. b p

One object of my present'invention is to provide a needle holder of the general type described in' said. application, in. which the needle clamping jaws'are so constructed that it is impossible for the needle to jump out of position or become released fromthe aWs accidentally during the operation of forcing the needle through hard or tough material that oiliers great 'theneedleJ I Another object is "to provide. a :needle holder that has all of the good features and characteristics of the needle holder described in said joint applicatiombm which comprises fewer partsand also parts which mlglily.

are of suchdesign that the instrumentcan be taken apart easily sterilized thor- Other objects and my invention will be hereinafter pointed out: #4..

In general design the needle holder that forms the subjectanatter of, my present ap plication is practically the'same as the needle holder described in said Saunders and Steedman application, and consists of needle-operating. inembers, that normally protectboth end,.por.tions .of. the needle and which areadapted to bemoved bodily to- ,ward and away from each other out of axial alinement with the .needle, so. as-to enable the needlev to, beinserted; in the 'material I being sewed-Mand thereafter drawn ,.COII1 pletely through said material, said needleoperating members being so constructed that theactflof gripping oneend of the. needle automaticallyrreleases the opposite endiof the needle. which had previously been grippedbyrthe instrument. k

Referring to the dra-wingspwhich illus- .-t1 ate thepreferred'forni of my invention; A

and JB designate two cooperating needle- I operating members of slmllar construction thatarearranged-parallel to each other. as

shown in Fig. 1. Said membersaremounted in such a manner thatthey can be moved of axiali alinenientwith theneedle during the-operation of sewing with the instrument,

sible .t'oiy the point: .or the eye of the needle to}:accidentallvistick into thepatient or into the il'iandli of '.,the surgeon using the instru- *bodily toward and awayfrom each other out movable part the needle-operating member which said Y parts form ismoved bodily toward and,

away from the other needle-operating member of the instrument. The'stationary part or body portion 1 of each needle-operating member is provided at its front end with a needle-clamping jaw 3 and the'cooperating 2 is also provided at its front end with a needle-clamping aw 1, said jaws having cooperating faces which are beveled in opposite directions, as shown in Fig. 8, so I V "being provided with recesses or cut-out poras to conform approximately to the crosssectional shape of the needle, which is of substantially triangular shape in cross section, and thus cause the needle. to be forced into engagement with bearing surfaces 2 and 2 on the movable part 2 of the needleoperating member when said jaws close.

The movable part 2 bears against one side of the stationary part 1, and said parts are connected together in such a manner that the part 2 can move longitudinally with relation to the part 1, so as'to open and close the cooperating needle- clamping jaws 3 and 4 on said parts, the movable part 2 of the instrument herein illustrated being provided with a laterally projecting lug 5 that fits in an open-ended slot 6 in the stationary part 1, as

shown in Fig. 2, so as to guide the part2 V longitudinally with relation to the stationary part 1. A head 7 on the lug'5 that laps over the outer erally with relation to each other. The movable part 2 of the'needle-operating member A is'also provided with a shoulder or abutment P, as shown inFig. 6, so as to position 4 the needle axially and preventit from creeping longitudinally in either direction, the.

shoulder 4 of the needle-operating member "A forming an abutment, against which theeye end of the needle is forced when the neefact that the needle is substantially triangular shaped in cross section, it'would be possible for the needle to force the jaws 3 and 4 apart, in case the needle moved outwardly or away from the bearingsurfaces 2 and 2 on the member 2 during the operation of fore ing the point of the needle through tough' or hard material. In order to guard against 7 this and eliminate the possibility ofthe nee- 4 dle jumpingout of positionor becoming released accidentally from theclamping jaws 3, and 4 when the point of the needle is subjected to pressure in a direction tending to face of the stationary part 1 E prevents the parts 1 and2 from moving latcause the eye end of the needle to fulcrum on the member 2, I have provided one or the other of the jaws 3 or 1 with a portion that laps over the outer convexed side of the needle, so as to prevent it from moving away from the bearing surfaces 2 and 2 on the member 2 when the opposite end or free end of the needle is subjected to pressure or to a strain of the character mentioned. In the preferred embodiment of my invention, as herein illustrated, the stationary jaw 3 of the needle-operating member A'is provided with a portion 103 that laps over the outer convexed side ofthe needle, as shownin Fig. 8, and thus prevents the inner curved side of -the needle from moving outof engagement with the bearing surfaces 2 and 2 on the 'i part 2 when the jaws 3 and 4: of the needleoperating member A are closed, the jaw 41:

tions so as to receive the forwardly-projecting portion 103 on the jaw 3 that laps over I V the needle.

If desired the aw 3 of the needle-operating member B can be provided with a similar portion 103, so as to eliminate the possibility of the point portion of the needle becoming released accidentally, in case the needleis subjected to an excessive strain through the material, but it is, of course,

not so essential to form the needle-operating member B in this manner, as the'time when strains of this character is when the point of or hard material. The laterally-projecting lug 5 on the part2 "that extends into the open-ended slot 6 in the part 1 is so positioned that it will strike against one side of the needle and move it longitudinally of the part 1 out from under the overhanging portion 103 on-the jaw 3 during theoperation of opening the jaws 3 and 4:,so as to release the needle. However, any other suitable means could be employed for forcing the needle out of the jaw 3, and therefore, I do not wish it to be understood that my invention" is limited to the precise means herein illustrated for accomplishing this result.

The movable part 2 of each needle-operating member is provided with a handle'2 -10O the needle is most likely to be subjected to V V piece '9 "thatis embraced by a pair 'of ears 8 on the handle portion of the stationary part 1. Instead of connecting the handle portions of the parts 1 and 2 together by means of a toggle link and employing a coiled expansion spring for raising the handle portion of the movable part. 2, as in the needle holder described in said Saunders and Steedman application, I have conend with a crosss neeted the handle portions of. the parts 1 and "2"of the needle holder herein "shown in a novel mannerthat simplifies the construction of theinstrumentand enables it tobe taken a art easily 'andsterilized thoroughly. As slioWnin Fig. 5 ,-the 'depen'dingtail piece 9 on the handle2 'is provided with an inclinedslot'ldwhich has an enlarged portion 1O itsi pper end. The ears 8 wl1ich en'ibrace said tail piecesupport a pin 11 that passes traiisyersely through the inclined slot 10 in said tail piecefWhen the handle2 is depressed this co'eperating inclined slot 10 and pin 11 cause\the part2 to'movet-o the left, *leoking at Fig.2,ftl1erebycausing the jaw 4 reset/ ray nanithe needle against the jawBbnthe stationary part1. VVhen said'handle Q is nioyed upwardly said cotiperating'inelined slot and pin will'cause the part 2 l to more in the oppdsiteidirection and thus release the needle, the tpwn-d movement of the handle 2 being effected by a Hat leaf sp ing 3"whose upperend is connected to the handle '2 and whose "lower end bears on 'thebhttonroi the guide-way orslot formed by the ears 8 that embrace the depending t ail"piece"9 on theha'nd'le.

said slot cotiperating with the pin 11 to form practically a frictional lock that tends to holdthe handle 2 in its depressed position. Thepin 11 *is-mounted loosely in the ears 8 and is provided intermediate "its ends with a reduced-portion'112 asshown in Fig. "9,

which is of the same diameteras the width of the slot 10 in the 'tailpiece 9." {Consequently, it is impossible for the pin 11 to move laterally out of the ears 8 when the handle 2' is in its raised position, and when the handle is in its depressed positlon with the pin 11 positioned in the enlarged portion 10 of the slot 10 The resiliency inthe han'dlecauses one wall of the enlarged portion of said slot to bear against one-side of the reduced portion of the pin -11, thus to exert sufficient downwardpressure onthe handle 2 when said handle is depressed to cause the enlarged portion 10 of the slot in" the tail piece 9 to register exactly with theenlarged end portions of the pin 11, thus permitting said pin to'be withdrawn. By forming the-instrument in this manner I reduce the number of parts of the instrument and enable it to be taken apart easily and sterilized thoroughly.

The handles 14 on the stationary parts of the needle-operating members A and-B are provided with cooperating lugs 23 and through which a-shaft 25 passes so as to pirotally connect the members A and B together, and thus permit the member B to be "inoved toward and away from the member with a gruird 29 that lies under the handles a 1 of the members A and B; and means of the same constructlon' that described in said appllcatlon of Saunders and Steedman is enmloyed for automatically locking: said guard to the members A. and B alternately during the opeartion of using the instrument'so as to enable the user to more accurately control the lateral movements oi? the 1 members A B. On the rear end of the shaft 25-is'atripping 'memberBQ thatlies underneath forwardly-projecting extensions 33 on the depending tail pieces 9 of the handles 2, saidextensions cooperating with the tripping member 32'to raise the handles 2 of the instrument so as to ca se the needle-clamping jaws to open in the manner more clearly described in said Saunders and Steedmanapplication. 7
