r Claims. (Cl. 128- 303) This invention relates to surgical instruments and more particularly to an instrument which facilitates the tying of infants navel cords by the application of an elastic band.

An object of the invention is to'provid'e a surgical instrument which is capable of expanding an elastic band, as a rubber band of small diameter, and holding the rubber band in the expanded position with an unimpeded and unobstructed passage through the center thereof so that the navel cord of the infant may be passed through the central passage of theband with the aid of some other instrument and then slipped from the navel cord bander for disposition on the navel cord.

A more specific object of the invention is to provide a surgical instrument which has a pair of handles, each handle being provided with a jaw at the outer end thereof on which there are elastic band supporting fingers, there being in addition to this a reciprocatory arm that has a finger at one end adapted to nest with the fingers of the jaws so that there is a three-point contact within the circle of the elastic band, together with means connected to the reciprocating arm for operating the arm in unison with the handles. s 1

Another object of the invention is to provide an instrument as described immediately above wherein there is a single elongated spring attached at one end toone of the handles and provided with a locking part at vthe other end engageable over a surface ofthe other handle. The function of the spring is to hold the handles releasably in a position to spread the band and hold the band spread and also to oppose the movement of the handles toward each other with a yielding force thereby automatically returning the handles to their spread position when the doctor releases his grip on the handles of the instrument. 7 t Y I V These together with otherobjects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals referto like parts throughout, and in which:

F gure 1 is an elevational view of a surgical instrument whichis constructed in accordance with the principles of the invention; t

Figure 2 is a side view of the instrument in Figure 1;

Figure 3 is an elevational view similar to Figure 1, but showing the instrument in the releasably locked, band spreading position;

Figure 4 is an enlarged, fragmentary, elevational view, parts being shown in section, illustrating the internal deiza l and construction of the instrument;

igure 5 is a sectional view taken a the line 5-5 of Figure 4; Ppmmmately 0n Figure 6 is a transverse, sectional view taken on the line 6-6 of Figure 4; and

Figure 7 is a fragmentary, perspective view of one end of the instrument.

The instrument 10 is constructed to stretch elastic of the handles.

bands so that they may be effectively applied to the nave cords of infants and function as a tie for the cords.

Rubber band 12 is a typical elastic band that may be ment about the pivot pin 18 which is passed throu gh aligned openings in

pivot plates

28 and 29.

Confronting slots

32 and 34 respectively are formed in the

handles

14 and 16, and these slots receive the flat arm 38. This arm is mounted for reciprocation in' the

slots

32 and 34 and passes through the open outer ends 40 (Figure 7) thereof. Slot 42 is formed longitudinally in arm 38 and has pivot pin 18 passed therethroughp The side walls of the

slots

32 and 34 and the pin 18 passing through slot 42 constrain the movement of arm38so that it is capable of reciprocation only.

Links

44 and 46 are attached at their, confronting ends to the extremity of arm 38 by means of pivot pin 48.

Recesses

52 and 50 are milled or otherwise formed in

handles

14 and 16 and they accommodate the outer ends of

links

44 and 46. The side walls of the

recesses

50 and 52 are parallel and function as guides for the links, assuring that they are capable only of oscillation about

pins

54 and 56. These pins are passed through aligned holes in ears 58 on handle 14 and ear 60 on handle 16, the ears of each handle extending inwardly from the confronting surfaces The outer ends of the jaws are formed with

flat shanks

66 and 67, while the outer end of arm 38 has an offset '68; with a part 69 coplanar with shanks 66and 67.

Fingers

70, 71 and 72 respectively rise perpendicularly from

shanks

66, 67 and the part 69 of the arm 38. These fingers have outer surfaces which are each in the form of. a partial cylinder and which combine toformja cylindrical elastic band holder. The innere'dges ofeach finger are arranged at approximately 120 degrees to each other so that when the instrument is closed (Figure1) the band holder is in the form of a cylinder more easily receiving and accommodating the band 12. Scoring {74 is on the surface of the band holder in order to increase thefriction'al bond between the fingers and the band 12; however, this is an optional feature;

Av one-piece spring is formed with an eye182 at one end through whichthe pivot pin 56 is passed, The eye is located between two of the three' cars 60- and works in the recess 84forrned in the handle 16'parall'el to recess 50. It is preferred that the spring 80 be made of wire, although'other forms of spring material [may be adopted. Passageway 86 extends through handle 14 between pivot pin 18 and pivot pin'54 and has the loop 88 on the outer extremity of spring 80*extended there: through. This loop 88 has a shoulder 90 at theinner end thereof which coacts with surface 92 formed on one wall 94 of'the passageway 86 in order to function as a latch to hold the handles in the retracted position (Figure 3). The bias of spring 80 is in such direction that one side of-the loop 88 constantly presses against wall 94, pushing the

handles

14 and 16 away from each other so that the nonnal'position of the handles of the instrument is as shown in Figure 1. When the instrument has its handles squeezed together slightly, the movement of the handles in this direction is opposed yieldingly by the spring 80, the spring being of such strength that it is capable of returning the handles to the position shown in Figure 1. But, when the handles are moved to the fully closed position (Figure 3'), the shoulder 90 engages against the surface 9'2""of"wall94and'holds the handles together as shown in Figure ,3; To overcome this latched condition, the, handles re, Spread manually .until the. shoulder, 90 .,ridesover surface '92, and then the stored energy inlhe. spring returns the handles to the fully open position (Figure l), ,f I

Astthehandlesaremoved from the fully open position to the closed position, links 7 44 and 46 slijde reciprocating, armuuirearwardly, thereby moving finger, 72" away from the fihgelfs 'lfl' and,7l,iwh ile fingers 70.and 71 are spread from,,each other, duet'ofthe pivotal motionof the handles 14. and 15."

Further, since numerous modifications. and changes will readily occur to those skilled inth'c art, it is not desired to limit theinvention to the exact :construction and operation shown and described, and'accordingly all suitable modifications and equivalents may be. resorted'to, falling within the scope ot he invention as claimed.
