SURGICAL roacn r s.

\Vhen opening cavities in the human body during an operation, heemorrh age frequently occurs, which is difficult to staunch. More particularly in the so-called Caesarian section, that is, the incision for opening the pregnant uterus, through which the child isremoved, exceedingly heavy haemorrhage occurs at the surfaces of section, which may frequently endanger. life. Apart from :the great injury to health caused'by such a great loss of blood, the quantity of blood gushing V out makes it ditficult for the'operator tool).- tain a proper view of the seat of operation; This disadvantage can be removed'by repeatedly mopping the place in question, for which purpose an assistant is required. This will not staunch the flow of blood, however, and this flow will continue 'uninterruptedly while stitching is proceeding. As, however, more particularly in the case of the Ceesarian section, several layers of rowsof stitches have to be put in, the closing'of the wound will occupy a considerable time, during which the haemorrhage will continue uninterrup'tedly, so that, as already stated,'there must be a considerable loss of blood. Forceps for clipping arteries are known, of course, but cannot be used alone, more particularly in the Caesarian operation.

The present invention has for its object to provide an appliance which is intended to be used in such operations,more particularly the Ceesarian operation, and which does not only cause the hzemorrhage to stop immediately, thus rendering. the entire seat of operation "visible, but so sets the edges of the wound with respect to one another that the operator can make the necessary stitches without trouble and without undue hurry, as isnow the case.

The appliance according to the invention consists of two pairs of clamping jaws which are adapted as regards their length and curvature to the requirements in each case. Each of these pairs of clamping jaws are placed, after the uterus has been opened, along one of the edges of the wound in such a manner that a sufficient portion of the edge of the Wound is left projecting beyond the jaws for applying the stitches. The two pairs of jaws are provided with joint parts with which they can be connected together, so that they can be turned with respect to one another for drawing the edges of the wound so close together that the stitches may be applied without trouble.

In the accompanying drawings a constructional example of the invention isillustrated. 1 Figures 1 and 4 show the pairs of clamp; ing jaws in plan view, f

Figure 2 shows the pair ofjaws of Figure 1' in side elevation; Figure 3'the same pair of jaws elevation;

Figure "5 shows the pair of clamping jaws united, but opened, in plan view, and

in front As will be seen from Figure 5, the appliance according to the present invention consists' of two pairs of clamping jaws,,jthe clamping jaws 1, 2, of whichiareof alength corresponding to the anticipated length of the incision. The clamping jaws may be curved in accordance with the shape of. the organ-to be operated on, or have any other shape. In cross section, the clamping jaws, as shown in Figures 3 and 5, have approximately. the form of a fiat ellipse, such that there. are no sharp edges. jawsmust besufiiciently elastic, so that' the. clamping pressure can act uniformly all over.

The clamping jawsl, 2, merge into the ex tensions 3 of the handles with such a curvature that each jaw has a part 4 extending beyond the handle extension, which serve the purpose, when the appliance is in use, of gripping the blood vesselslying beyond the end of the incision, and stopping llZBIIlOIF rhage. Onthe-handle extensions 3 are the handles 5. :By this arrangement, the os pubis is, as it were, hrid'ged over'when applying theinstrumentduring the Ceesa'rian Figure 6 .is a front elevation'of Figure 5.

The clamping V operation, so that the instrument can be applied either from the lower or the upper end of the incision. In each pair of forceps, the handle extensions 3 are pivoted by means of the screw 6, so that the clamping jaws of each pair can be moved by means of their handles. ing jaws, after they have been applied to the edge of the wound, any suitable locking device may be provided. In the constructional example shown in the drawings, one handle has fixed to it an arcuate bar 7 which, as indicated, is provided with notches or incisions, in which a short bar8, fixed to the other handle 5 of the same forceps, engages by means of a tooth, not shown in the drawing, so that the pair of clamping jaws can be locked in the required position, and held there. For connecting the two pairs of forceps together pivotally and releasably,

For securing each pair of clampone handle extension of each pair of forceps has fixed wit a threaded pinz'or the like 9'," on to which a. nut is screwed. Over the two pins or the like 9 of the two pairs'of' for ceps, there engages a -bent membei L lia ving a slot 12, so that the pairs of forceps are so 'thatthe'view of the seat of operation is r unob'scured, and, whatis moreimportannthe r otherwise'un'avoi'dable' lossof blood cannot take place. For closing the wound :by'stitching, the two pairs of "clamping j aws: are. app'roa'ched towards one another, whereupon the nuts 10 are tighteneddown on1the pins 9, for clamping the member 11,-when the two pairs of'cl'amping aws have been so a djusted relatively to -one' an'o'ther'th-at' 'the edges of the wound are close together. The stitches are then putin' in' the usual manner almost c to'the endof the wound. "For completing the stitching, the two pairs-of clamping. jaws are separated by releasing t'he nuts 1,0, and 1 drawing them apart, so that they can be Withdrawn separately out of part ofQthe wound not yetstitched.

Any material, for instance, steelpmay be used in the manufacture"of the appliance or,

for reducing the weight, any suitable iiight metal, as long'as it has sufficientlelastieityand strength. The means'ifor locking each position with respect to each.

pair of clamping jaws and-the constructional 'form"ofthe releasable pivotal connection for the two pairs of clamping jaws may of course be eflectecl in any other suitable: mannerth-an th at' shown in the drawing.

Having now described my invention, what I elaim as new and desire to secure by Letters Patent is I j lfAn appliance for preventing haemorrhage during operations involving incisions in 'the walls of cavities in-the human body, comprising in combination twopairs of forceps, each. pair of forceps comprising two pivoted members, a handle at one end of the member, a clamping jaw at the other end of the member, and a bridge member. for connecting the two, -pa-ir s'off forceps suchlthat they can be adjusted'independentlyofwone another and rotated with respect to one another for drawing'the edges ofithe' incision together, and canebe taken apart for'removing the vclamping jaws fromthe incision, as set forth. I 1

2. An appliance as claimedinfclaim 1, in which the-jaws of the-members ofthe two pairs of forceps are of length corresponding tothe length ofthe incisiomare curved in accordance with=the curvatnreof the wall of the cavity, and extend backwards towards the handles beyond theflpart-offthe pivotal limbs remotest from the hinge,v as andflfor the purposesetforth.

3.' An appliance as claimed in claim 1 and in which apart for connecting thepivotal members and'the jaws extends firstinone plane and'then in a plane at right angles thereto, as and for the purposeset forth.

4. An appliance as claimed in claim .1, and comprising locking means for securingr the combined pairs of clamping jaws in -de-- sired position with respect to one another, as and for-the purpose set forth.
