WOUND-CLIP FORCEP-S.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed November 11, 1914. Serial No. 871,438.

To all whom t may concern Be it known that I, GUsTAv RIHTnR, a citizen of the United States, residing 1n the bo-rough of Brooklyn, city, county, and

State of New York, have invented the following-described new and useful Improvements in found-Clip Forceps.

The invention relates to wound clip forceps and the object is to provide an instrument combining in a. superior manner simplicity of construction, convenience and reliability of operation, freedom from derangement, ease in loading with clips, and thorough sterilizability.

The invention comprises a 'number of novel features, which will now be described, and while the best results are obtained when all are used in conjunction, as herein illustrated,'certain of the improvements may be used without others, or in specifically different combinations.

In the accompanying drawings, Figure l is a plan View of the device in position for use; Fig. 2 is a vertical longitudinal section, with parts in elevation; Fig. 3 is a crosssection on line III-III; Fig. et is a crosssection, enlarged, through the pivotal portions of the forceps members, and looking forward toward the jaws, the pivot pin being omitted; Fig. 5 is an enlarged front or end View of the magazine showing a clip at the end thereof; Fig. 6 is a fragmentary bottom plan view, with the jaws partly in section, showing the foremost clip held by the jaws preparatory to its bending; Fig. 7 is an enlarged view showing a clip and the pusher in front elevation and the clipbearing wire in cross section; Fig. 8 is a front View of the forceps, on the scale of Figs. l to 3, illustrating the bending of a clip by dotted lines. Fig. 9 is a perspective view of the pusher alone; Fig. l0 is a horizontal sectional view taken at the rear of the magazine, the gate being shown closed in full lines and open in dotted lines; Fig. l1 is a plan view illustrating a few of the clipsV on the guide wire and the pusher in its relation thereto; and Fig'. 12 is a bottom plan detail of one of the clip-applying jaws and its abutment stop 26.

The body member of the device is a magazine designated 2, preferably substantially straight and of boxed form in section, and also open at its front andv rear ends, the

rear end being the'entrance into which the clips are introduced and the forward end being the delivery end from which the successive foremost clips are fed to the forceps members 3 in the manner presently to be described. In this magazine the clips 4 are received without necessity of removal from the supporting wire 5, on which they are furnished, and which when in place in the device performs the function of an auxiliary guide for the clips in their feeding movement, thus becoming a part of the apparatus. The wire, however, is not a necessary part of the feeding means and may be omitted since the interior formation of the magazine could be such as to accommodate the clips without it. It is, however, an important advantage to be able to charge the magazine by a single operation and the wire-receiving magazine therefore forms a correspondingly important part of the invention. As clearly shown in Fig. 11, the said wire is of substantially elongated hairpin form with a laterally projecting head 6, adapted to enter the slots 7 (see Figs. 2 and l0) cut in the rear ends of the side walls of the magazine, near the bottom, and affording means for positioning the wire and holding it with its free ends within the magazine. A gate 8, conveniently in the form of a spring strip pivoted at 9 to the bottom of the magazine and having its rear end 10 upturned, engages behind the end of the wire and confines the head 6 thereof in the recesses?, whereby displacement of the wire is prevented. As indicated in Fig. 10, this gate may be swung to one side, being first bent down for the purpose, in order to permit an empty wire to be removed and a full one. loaded with clips, to be inserted.

The magazine or inclosure proper is of appropriate width and depth internally to take the series'of clips, in edgewise alinement on the wire, that is to say, with their backs in the same plane, parallel to the general plane of the magazine. At its forwardend the bottom wall is cut away for a substantial distance, leaving an opening or hollow l1 which will accommodate the lips of the wound, and this cutaway portion is beveled upward, as shown more particularly in Fig. 2, to provide further clearance. The margins of the opening 1l coperate with the side and top walls of the magazine to form narrowing channels 12, which, as shown in Figa-5, afford sie ternal guides for thee-nds or eyes of the clips, insuring delivery thereof in liXed relation to the clip-applying members, presently described. `While these guiding channels are shown only at the forward end of the magazine, they might obviously extend farther i'earward if desired. y

The means for feeding the clips lengthwise of the wire and of the magazine comprises a thumb push formed by a clipenga ging slide-plate 14 disposed immediately below the top wall of the magazine and a thumb projection 15 above the same, the two -being joined by reduced portion, leaving grooves 1G between the two said portions, which grooves fit over the edges of the longitudinal slot 17 in the top wall of the magazine. The pusher is inserted in the slot after` the wire-full of clips has been introduced and before closing the gate, and its forward end engages the rearmost clip on the wire, and is capable of advancingthe line of clips the full length ofthe magazine.

The clip-bending vor applying devices comprise crossed forceps members 3, which are fulcrumed as levers of the first class at a point very near their forward ends and on top of the forward portion of the magazine. Each member consists of a short jaw portion or nib 19, and ay relatively long grip portion or handle 20, the nibs being extended downward in front of the forward end of the magazine, as shown in Figs. 2 and 8, and the grips diverging rearwardly at opposite sides of the magazine. 1n the particular construction shown, the pivot Q1 for the levers rises from the forward portion of the top wall of the magazine, at the end of the slot 17, and has a relatively large base to engage the bearings 22 of the levers. A washer 23 is placed above the members, embracing the portion of the pivot of reduced diameter, just above the base, while af nut 18 screwed to the end of the'pivot, holds the parts'together but so that they can be disassembled in the obvious manner. A. spring 9A held by a groove in the washer 23, and with its ends 25 held in holes in the grips 20, servesto urge the latter to their eXtreme divergent positions. These positions are determined for each member by the engagement of the rear side of the nib 19 with the front face 26 of the magazine, as illustrated more clearly in Fig. 12. Wvhen holding this normal position, the lips Q7 on the nibs occupy positions in which they serve as stops to limit the advance of the foremost clip under the action of the thumb push. 1n rear of each lip 27, the nib is concaved to form a virtual eX- tension of the channels in the magazine and of appropriate depth to receive but a single clip, which will be retained therein until the nibs are forced together by the opera-tor. VA 'ter the-clip has been bent in the manner,

its shortened length will permit it to separate readily from the nibs as soon as the latter are again opened. The return of the nibs to the position in which they abut against the faces 26, brings them in proper alineinent to receive the next successive clip, and the advance of the latter is definitely and positively limited by the abntment'stops or lips 27. f

In use, the magazine is relatively stationary in the hand of the operator, and VYthe grip portions of the forceps are compressed by the thumb and foreiinger to bend and ap-v ply the clips. After each application the pusher is pressed forward by the thumb, to advance a fresh clip into place between the jaws, and when the series of clips is eX- hausted, the gate at the back is opened, the

wire and thumb push removed, and a fresh wire with clips thereon is inserted. The easy disassemblage of the parts, as well as the open character of the magazine, enable the-instrument to be quickly and thoroughly sterilized, as will be evident. It will be observed, moreover,-that the construction is such that clearance is provided at the back and under side of the foremostv clip between the nibs at the end of a stationary magazine wherein the clips are guided in edgewise alinement, the said Aclearance space permitting the bending and application of the clin without the necessity of any movement on the part of the magazine and in plain view of the operator, and in this respect the in- `vention constitutes an embodiment of the construction broadly claimed in my priork application filed July 22, 1913` Serial No. 780,483, which differs specifically from the present case in that the forward clip-retaining instrumentalities are therein carried by the magazine part, instead of being formed on the forceps members as illustrated herein. By the employment of lever members of the first class, and having a considerable leverage as indicated, a new and important the device operates with a spring action, y since the movement of the parts in such devices precludes the steady'y application of power to the bending of the clip.
