' scanne: (01.129325) This invention relates to a means for use .in connection with stopping of bleeding, more particularly in connection with surgical operations which are performed in such elds where the usual method of tying blood. vessels is technically diilicult.
The control of the bleeding which .occurs during a surgical operation, as :for instance, `when referred to and illustrated in the accompanying Y drawing, but it is to be understood that changes,
removing the tonsils, is .a very important `part of such an operation.y The routine procedure consists of applying pressure in the, fossae4 by means of gauze Sponges and undoubtedly in many cases this will suffice to secure stoppage of bleed--v ing. Nevertheless, even though cessation of the bleeding has been achieved, itis a matter of chance whether a late bleeding will not occur during'the early convalescence The `length of time `ever which this pressure is to be applied is usually not less than three minutes,y but often considerablymore.V Often, too.,V the `bleeding will not stop by simple pressure, and other methods must be resorted to.
The, method most frequently used is clampingA the bleedingpoints and `applying avcatgut liga ture on them. This may bean adequate way of controlling the bleeding, but `the Yligation itself requires special skill of a high degree. 4lilvery I so often it .happens that no sooner the artery forceps is removed from'its position the ligature will lose its hold underthe eyesof thesurgeon',
because it wasV not suioiently tight, or the cat gut tears while `being tightened The whole procedure must Vbe done over andv often enough the situation becomes quitey serious. The suture is hardly an easier procedure. v
Besides the difficulty of these methods, the fact that considerable time is spent in stopping the bleeding, makes a more efcient method l'of ligation in the tonsillar fossae highly desirable.`
Efficiency and speed in ligation is just as much, if notl more, needed in late hemorrhages after tonsillectomy and other surgical operations.
My invention has for a further object to expedite and satisfactorily apply',vby force, an automatically constrictibleligature relative to a bleeding point to stop bleeding. y i y K My linvention has for its,A further object to provide, in a manner as hereinafter set forth, -a comparatively simple device for applying an auto.. matically constrictible ligature for the purpose of stopping bleeding.l
Embodying the objects aforesaid and others which may hereinafter appearfmy invention consists of the novel yconstruction,combination and arrangement ofy parts as willv bemore specifically tion of that portion of the device ends of the handles, and
. handles i3, I4, as is well known in this art. The forceps have upper and lower termination i tapered contour.

'The jaws I5, 1 I6 arelso formed that when they are closed they provide theforceps with a forward terminal portionof hereinafter referred to as superimposed `supporting elements. `The jaws-l5, l6-will beherein-v after referred to as combined expender`A and "grip members. f .i A slidable pushing or operating roclll is closely applied -along one of the sides of the` elements The elements Il, l2v will be y or members II, I 2.` Therod I1, intermedateits ends is secured to the outer faces of spaced, aligned, split, resilient, substantially Ovoidalshaped Icombined guiding and coupling members I8, I9 which overlap and grip the elements I I, I2. guides for the rod I1, but also act as couplings for slidably connecting rod I1 to said elements II, I2.

beyond the hinge or pivot of the jaw I; A`
handle or loop-like grip 22-is at the rear end ofg The members I8, I9 not only constitute the rod I1. The ligature which is applied by the device consists of a comparatively thin resilient rubber disc 23 having a minute axially arranged opening 24. The disc 23 possesses a characteris- .zor
tic of being automatically constrictible when'apv plied Vat the bleeding point. When the device applies a ligature relative to a bleeding point which is difficult of access, byy
Way of example, after a tonsillectomy and with the bleeding point indicated at 25, Figure 1, the disc willbe pulled 'over the closed jaws I5, I6 toan extentV to abut the forcingA sleeve 2D, as shown by Figure 5, and when'so positionedthe wall of the opening 24 will 'be stretched. After disc 23 is in the position shown by Figure 5, the
jaws are opened and positioned about anddisposed in relation to grip the outer portion of the tissues. surrounding the bleeding point, Aas is shown by Figure 6. With the jaws in the position shown in Figure 6, the rod I1 isthen pushed forwardly carrying the sleeve therewith, whereby the latter will'force the disc 2 3olT the jaws to a position to surround and tightlyrgrip together that portion of the tissues inwardly of the portion gripped by the jaws and thereby stop bleeding. The position ofthe disc will then be as shown ley-Figure 7. The forceps are then reare gripped by the jaws, and the disc 23 will then appear as Shown by Figure 8.
