J. B. BACON ARTERY FORCEPS Jul 18, 1933.

Filed May 18, 1932 lll llilll 7' five; '07? Patented July 18, 1933 PATENT 1 OFFICE JOSEPH LB. BACON, OF MACOMB, ILLINOIS ARTERY FORCEP S Application filed May 18,

This invention relates to improvements in artery forceps and, more especially, such an instrument designed for use in closing the ends of severed arteries. The instrument finds its principal use in connection with surgical operations where arteries are severed and the ends must be closed to prevent excessive loss of blood.

It is well known that the ends of severed arteries can frequently be closed by twisting the same, and after being so twisted, it is not necessary to retain pressure on the end. It has been the practice heretofore to close such arteries with an ordinary forceps by grasping the end and then twisting the instrument.

The principal feature of my invention 1s the provision of a forceps of the character described that will automatically twist the end of the artery as the jaws are closed.

This is accomplished by providing means for causing relative sliding movement of'the jaws with respect to each other as the same"- are closed on the end of the artery. This N V sliding movement gives the twisting required to close the end of the artery.

Other features and advantages of my'invention will appear more fully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawing- Figure 1 1s a view 111 side elevatlon showing the forceps open; Flg. 2 1s a similar vlew M showing the same closed; Fig. 3 is a top plan view showlng the same closed; Fig. 4

is a view taken as indicated by the line 4 of F ig. 2; and F1 5 1s a view in perspectlve of the jaws, showing the sliding movement which accomplishes the twisting of the end of the artery.

As shown in the drawing, the device includes two jaws with handles plvotally attached in the conventional manner. As

here shown, the upper jaw is indicated by1 0 and its handle by The lower jaw 1s same are closed.

movement being indicated by the arrows in Figs. 2 and 5.

In Fig. 5, the end of an artery is indicated by 16 and it will be seen that the sliding movement of the jaws referred to will serve to twist this end, as above described.

As here shown, the lower jaw 11 is provided with a longitudinally arranged central raised rib or ridge 11 accommodated by a cooperating similarly arranged recess 10 in the upper jaw.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention ,as disclosed in the appended claim, in which it is my intention to claim all novelty inherent in the invention as broadly as permissible, in view of the prior art.

lVhat I regard as new, and desire to secure by Letters Patent, is:

A forceps of the character described, in-

cluding; two jaws with handles, pivotally
