1 Claim. (Cl. 12S-321) The present invention refers to a surgical torcep, and more particularly to a manual utensil which, in the manner itis combined in its active part it tends to be an ideal forY all kinds of surgical interventions such as bilious, thyroid, gastric, intestines, appendicular and specially those presented in vascular netting.

This is a mechanical instrument which acts as dissector, can be used as thread `carrier as `well as hemostatic occluser, thus `being an instrument that may be used in three applications and may be used in an operative cycle without need of employing other elements ad hoc.

To this end said forcep has uneven jaws, so that one of them extends with a projection precisely starting from the extreme of the other jaw so that the rst projects as a terminal. Said projection possesses an eye as a sewing needle, which being threaded with an appropriate thread may be passed below a vein so as to allow the tieing or binding of veins, and since this operation is done through passing the orcep below the vein or element to be treated, it remains as a pincer in position to press the vein and allow other fastenings. Same can also be used as dissector.

The forceps can be made in different sizes, Iand according to its application it may have its jaws directed to the right, left or upright, so that the doctor or surgeon may act with ease and a perfect vision of the surgical zone.

Apart from what has been stated, several are the objects pursued by the present invention, amongst which may be cited the fact of expediting the technique and shorten the surgical time, as the forceps deals in the greater part of the operative actions.

Another object is that of simplifying the movements of the operative process by not requiring, apart from the pincer, any other instruments apart from the cutting scissors and catgut or thread employed in the tieing of veins.

Another object of the invention is that of alleviating the surgeons task as well as that of the instrument nurse, as it suppresses a great number of movements as it does not require changes or substitution of instruments.

' Another object is that of offering to surgery an instrument that may be classified as multiple, as it carries out several specific functions, without the need of changing instruments.

The further objects of this invention will be shown throughout the following specification, which for a greater cleal'ness it has been illustrated with several drawings in which:

Fig. l is a perspective view of a pincer in one of the examples of execution in which the jaws are rectilinear and only the projecting terminal with a threading eye, is curved upwards.

Fig. 2 is a perspective View of the essential part of the forceps in a dierent execution in which the jaws are laterally elbowed towards the right in obtuse angle.

Fig. 3 is a forcep with jaws in obtuse angle, as in Fig. 2 but projected towards the left.


Fig. 4 shows another kind of forcep in which the jaws are elbowed nearly as rectangle towards the right.

Fig. 5 is almost the same as Fig. 4 but with jaws directed towards the left.

Fig. 6 is a graphical demonstration of how the terminal of the forceps is threaded in order to pass the catgut or thread below a vein or any other element.

Fig. 7 shows how the end of the pincers is passed below the vein 'so as to prepare the thread that is to tie it.

Fig. 8 is another demonstration of the following step showing how the thread is unthreaded with another pincer before the tieing operation. p v

Fig. 9 shows the following step to No. E in which the thread is tied with a knot whilst the forceps nips the vein next to the knot but leaving suicient space to cut the vein.

Fig. l0 is the subsequent step in which the vein is cut with a scissors whilst it is maintained by the forceps.

Fig. l1 shows how, after cutting the vein, a thread is passed behind the blocking forceps so as to effect another knot and iinally, l`

Fig. 12 in the last step in which it shows that after making the second knot, the forceps is taken out.

In allthe drawings the same reference numbers indicate equal or corresponding parts, the various elements being indicated by letters.

As may be seen in the drawings, a and b are the two pieces which as levers act as scissors in the cross part l, so that the piece a possesses a potential :arm 3 of piece b, whilst on the other hand, that is after 'the cross part, the piece a possesses a jaw 4 in play with jaw 5 of the `lever piece b.

The arm Z of piece a has a ring 6 for one of the fingers of the operator whilst arm 3 of piece b has a ring 7 for another finger of the same hand, so that the surgeon operates the pincers as any `common forceps, and as in all instruments of this type, the arms 2 and 3 possess catches it and 9 forming a broach for maintaining the forceps in closed position after nipping a vein or other part in the op erative zone.

ln the closed position of the forceps, the jaw 5 ends precisely in the plane 10 of jaw 4 which, forming in this plane a step, is projected with a terminal 1.1 which rising with a greater thickness than that of its proper jaw 4, is projected outward of the reach of jaw 5, so that said term'inal 11 remains as a sort of point at the active extremity of the forceps.

Terminal 11, with its blunt point, possesses an eye 12 which is threaded with a thread 13 which may be catgut or any other kind appropriate for the operation, for, as stated, this instrument is applied for cutting and passing threads, apart from its hemostatic conditions of a pincer, and with the same projection assumed by terminal 11, the instrument serves for dissecting, opening or separating one tissue from another.

The terminal 11 can be projected in the same displacement plane of the jaws of the forceps, but as jaw 4 must always be disposed below when the surgeon employs the instrument, the terminal 11 must in this case be directed upwards, as in Fig. l in which, both jaws 4 and Sbeing substantially rectilinear, terminal 11 alects a form of curved point in ascending direction; the forceps wit-h the characteristics of Fig. 1 is apt for appendix and varicose surgery.

Dealing with bilious, gastric or vascular surgery, the jaws 4 and 5 should be elbowed as shown in Figs. 2, 3, 4 and 5, in which that of Fig. 2 shows an elbowing in obtuse angle, projected outward to the right so as to operate on the right hand side of the surgeon; that of Fig. 3 is projected towards the left; in Fig. 4 it shows an elbowing in right angle with projection towards the right and Fig. 5 is projected towards the left.

Thus, in a surgical intervention, the surgeon may use the described pincer as a multiple instrument for, barring the cutting or getting hold of any thread, said forceps does practically all the work. r l

' In eifect, choosing a Aspecial model for each case, when the surgeon handles this instrument he is able to effect most of the different requirements of his work.

' For. instance, if dealingin varicose surgery, When using a .forceps of Fig. 2, after dissecting with terminal 11, and refaching'apart of vein 14 he must thread the eye 12 with a vthread 13, Fig. 6, and said thread is passed with the forceps below said vein 14 as shown in Fig. 7, so that said thread 13 be disposed to surround said vein. In the next step the thread 13 is caught by an auxiliary pincer 15 (Fig. 8) so that unthreading from eye 12 both ends may be caught so as to effect the knot, as shown in Fig. 9. When the knot is effected with thread 13, next to same,

knot is made in the free extreme after which the forceps is vtaken out' as shown in Fig. 12.

Within the terms of the appended claim, various modiiications of `detail and structure may be made without departing from the scope or principles of the invention.

I claim:

Surgical forceps comprising in its active part, a set of two biting jaws, one of which being longer than the other posseses a free projection forming a terminal provided but leaving a space for cutting, the hemostasis is done with the same forceps as also shown in Fig. 9. The next step isthat. of cutting the vein 14 in the space comprised betweenthe knot and the occlusion made by the forceps (Fig. 10) which is done by means of a scissors 16. After the cutting has been effected, one of the free extremes of the vein 14 is held by the forceps, and a thread 17 is passed as shown in Fig. 11.
