is'claims. (01.128440) This invention-relates to anovel sutureihemostat whereby the edges of a wound may be drawn together by sewing or inserting a thread in an appropriate manner well known in the medical profession. The purpose of this suturing is to prevent bleeding at the incision.

An object of my inventionis to provide a novel suture hemostat in which an efiective knot or loop can be tied in a simple and effective manner by the physician for thegpurpose of drawing together the edge of a wound.

Another. objectofmy invention is to provide a novel 'suture. ,hemostat including a bobbin and involving a novel, means of moving the bobbin or shuttle from side to side in order to forma knot or stitch. g

A feature of my invention is to provide anovel suture hemostat inwhich the needle and the shuttle or bobbin are self contained in the instrument, as well as a novel means to movethe shuttle or bobbin from side toside while the stitching is continuing.

Another.- feature of my invention. is to provide a novel manually operable meanstc, move the shuttle. or bobbin from side to side while the suturing is continuing.

Other objects, advantages and features ofinvention may appear from the" accompanying drawing, the subjoined detailed description and the appended claims. I I

Referring more particularly to the drawing, my

suture hemostat l includes a pair of jaws 2--3 which are pivotally secured together by the pin this. needle projects.upwardlyv from therjaw .2

. and. is adapted to 'fit between the bifurcations 5 of the jaw 3 in the closed position of the instrument. This closed position of the instrument is perhaps best shown in Figure 4.

A lateral groove or recess 1 is formed in the needle 6 and in the closed position of. the instrument this grooveis aligned .with the bifurcations 5 of. the. jaw 3 and. also directly in alignment with the shuttle or. bobbin 8. This shuttle is adapted to move laterally of the instrument and from one bifurcation to the other of the jaw 3.

In. moving laterally, the shuttle 8 passes through the groove 1 of the needle 6 and in this movement the end, of. the threadv 9- is passed through the loop 10, thus forming the proper knot or stitch which permits the edge of the incision to be drawn together to prevent bleeding, which is well known in the art. The end of the thread is attached to the bobbin 8, as shown at ll,.-and. the thread passes through aaslot l2 in pressing' these fingers the. shuttle will be forced 4. The outer end. of the upper jaw 3 is bifurcated, as shown at 5, the purpose of which will be further. described.

A needle 6 is fixedly mounted inthe .iaw {and thebobbim thus permitting thethread to move lengthwise ofthebobbin and permitting the bob- .bin'to. move into the opening I5 or [6 in the bifurcation'of thejaw 3 and without binding the bobbin.

To move the shuttle 8 back and forth from one bifurcation to the other, I provide a pair of flexible spring fingers |3-l4 preferably formed of wire, which are attached at one end to the jaw 3, the other end of each spring. fingerprojecting into the outer ends of a lateral bore. 15 or 16 which are formed in the bifurcations of the Jaw 3. The spring fingers l3l4 thus will engage the outer. end of theyshuttle 8 and by delaterally from onebifurcation 5 to the other, thus moving through the. groove 1 .of the. needle .6 .andforming aproper tie with the loop. [0,.which is constantly formed in the thread 9. The needle S is provided with a bore l7 adjacent its tip and the thread 9 passes through this bore, as best shown-in Figure 2. The shuttle 8 is somewhat longer than thedistance between the bifurcation of the jaw 3 so that the shuttle can span this *opening; In operation, the jaws 2 and 3 are "brought together which" places the parts in the position shown in Figure 1. The operator now depresses either the spring finger I 3 or the finger ll, depending upon which side the shuttle 8 is resting. When the finger l3 or I4 is thus depressed, it will pass into the end of the bore ['5 or IE, thus pushing against the end of the shuttle 8 andforcing this shuttle across the opening and pass the needle 6 and into the opposite lateral bore.

In Figure 6, I have shown a modified form of my invention, again including pivoted jaws [8- IS, the lower jaw l8 being provided with a needle 20, which is identical in construction to the needle 6, previously described. The needle moves into a vertical opening 2| in the upper jaw [9 when the instrument is closed. A shuttle 22 is mounted in the upper jaw l9 and this shuttleis adapted to move lengthwise of the jaw I9, as shown. A guide tube 23 is secured to the upper said other jaw having an opening therein into which the needle may extend, a shuttle mounted in the other jaw and movable across said opening and from one side of the needle to the other side thereof, said needle having a hole therein through which the suturing thread extends, and said shuttle having a slot therein for the securement of the end of a suturing thread, and manually operablemeans engageablewiththe shuttle jaw I9 and a flexible spring wire 24 is mounted I in this arcuate tube and is moved within the tube by the pin 25 attached tothe spring wire. The shuttle 22 moves into suitable bores 26in the jaw I9 and is moved across the op ing 2|;

by means of the wire 24 which presses against the back of the shuttle 22 in the same manner having a slot 28 extending from one edge thereof,

as shown. The needle 29 extends into this slot in the closed position of the instrument and the shuttle 30 moves across this slot in the same mannor as the shuttle 22, and is actuated in the same manner as the shuttle 22, namely, by a flexible wire 3!, which moves in a guide tube 32. In

Figures 6 and 7, the shuttles 22 or 30 are moved across the openings 2! or 28 by the flexible wire 24 or 3|, and this wire is caused to engage either end of the shuttle by the manual manipulation of the pin 25, all of this occurring after the jaws l8-l 9, or 26-27 are closed.

My suture hemostat will facilitate the securing of the hemostasis of long incisions, such as hysterectomy or the'cutting of greater omentum in gastric surgery. That is, my instrument will efiectively tie off the edge of an incision to prevent bleeding.
