Application April 24, 1946, Serial No. 664,519
This invention relates to umbilical clips and to forceps for applying such clips to umbilical cord.
Broadly, it is an object of my invention to provide a clip which will, upon pressure, cut the umbilical cord and automatically apply the clip to the umbilical cord so that it firmly adheres to the cord and seals the same.
More specifically, it is an object of my invention to provide an umbilical clip to be used with forceps so that the clip can be quickly applied to the umbilical cord effectively compressing the umbilical cord without closing the blood vessels passing through the center of the cord at the same time severing the cord simultaneously during the same operation.
Heretofore, a number of mechanical methods had been tried but apparently without satisfactory success. The previous method used is to tie the umbilical cord with gut. However, this method is slow and is not entirely reliable. Later methods employed other means, such as compressed clips which are generally attached to the umbilical cord and the cord then has to be severed after the clips have been applied. This method involves expensive instruments and the mother and infant run the danger of developing umbilical hernia due, sometimes, to the delay in severing the cord after the clips have been applied. With my clip, the possibility of a secondary hemorrhage will be eliminated and the application of the clip simultaneously severs the cord, the clip being quickly applied, thus eliminating all moisture from the clamped tissue, so that the blood supply is entirely out off from this tissue, which eventually atrophies and the dead tissue drops off with the clip. During the compression of the clip upon the umbilical cord, the possibilit of infection is minimized since the moisture is eliminated, thus retarding the possibility of bacterial growth.
My clips may be numbered or lettered to identify the infant and the mother, so that the possibility of error is avoided.
A further object of my invention is to provide holding means for the clip within the jaws of the forceps so that the possibility of the clips springing from the jaws of the forceps is entirely eliminated, and the clip is positively positioned within the forceps jaws.
A further object is to provide an identical light clip which may be easily sterilized so that, after it is applied to the infant, infection will not set in, nor will the clip irritate the body of the infant.
Still a further object of my invention is to provide an umbilical clip which will produce complete hemostasis by flattening the blood vessels of the creasing the cord to obtain a perfect closur in order to preclude any leakage or bleeding.
Still another object of the invention is to provide a perfected clip having the advantages of umbilical hemostat, so that all danger of its becoming unintentionally unfastened is eliminated.
Still another object is to provide a pair of forceps for rapid and easy application of the clip with ratchet means so that the clip can be speedily and safely applied by the forceps, simultaneously severing the cord and preventing the handles of the forceps from separating to relieve the pressure at the jaws.
A further object of the invention is to provide rounded edges at the sides of the forcep jaws to take up any pressure upon the umbilical cord in order to prevent the cord being severed where not intended.
For a fuller understanding of the nature and objects of my invention, reference is had to the following detailed description in connection with the accompanying drawings in which:
Fig. 1 is a side elevation of the forceps used for the application of the umbilical clip, the clip being shown in dot and dash lines.
Fig. 2 is a side elevation of the forceps shown in Fig. l in partially closed position.
Fig. 3 is a fragmentary side elevation enlarged showing the jaws of the forceps in longitudinal section.
Fig. 4 is a fragmentary section of the jaws of the forceps in closed position with a clip between the jaws of the forceps in closed or applied position.
Fig. 5 is an enlarged section taken through line 5--5 of Fig. 4.
Fig. 6 is a perspective view of the clip in open position.
Fig. '7 is a transverse section of a modified umbilical clip under compression.
Fig. 8 is a transverse section of another modified umbilical clip under compression.
Referring to the drawings, numeral Ill represents a forceps comprising an upper jaw I I and a lower jaw l2, jaws II and I2 pivoting about a pivot member l3 and continuing beyond pivot l3, terminating in projecting handles l4 and I5, handle l4 being the upper handle to the end of Which is attached a flexible ratchet l6 having teeth I! and which is adapted to receive the end l8 of the lower handle 15. When the laws I l and I2 are in separated position, the handles I4 and [5 are spread apart as shown in Fig. 1 and as the handles are compressed, the end l8 of the lower handle rides upward along the ratchet teeth I] 3 until it reaches the uppermost tooth l9 when the jaws II and I2 are in closed position. The spring 20 is attached to handle I by screw 2|, the fiexible end 22 of spring rides along the inside edge 23 of handle I4, exerting pressure between the handles.
The upper jaw II has a longitudinal channel 24, an anvil 25 and a depending pin 26. The lower jaw has apin 21 having a, hollow central portion 28 to receive the projecting portion of pin 25 therein as shown in Fig. 4. Pins 26 and 21 are firmly attached in the ends of jaws II and 1-2, respectively.
Referring to Fig. 6, I have provided a clip 29 comprised of opposed legs 30 and 31, the leg 30 having a hole 32 at its end and opening 33 adjacent the hole 32 and a longitudinal slot 34. The lower leg 3! has a hole 35 at its end in alignment with hole 32 when the clip is compressed, a projection 36 bent inwardly from the material of the clip aird inalignm'ent withhole 33 is placed adjacent "hole A blade '31 is *bent inwardly at right angles to the inner face of leg 3! in alignment with'slottfl, "so that when the clip 29 is compressed, the end of the' bla de 31 will enter the slot 34, shearing the umbilical cord passing between the legs 39 and 3! 'a nd'simultaneously compressingfthe umbilical cord between the'inner surfaces of legs 39 and '31, so that, the clip 29 is firmly c'l'am'ped upon the "end of the sheared umbilical cord. Legs and 31 are retained under slight ztehsi'on by the'ciirved central portion 38.
In order to use and'apply the umbilical clip 29 to the umbilical cord during childbirth. the clip is placed between the jaws II and I2 of the forceps, spin' 2 'i passing through hole 35 and .pin '26 passing through hole 32 of the clip. The handles T4 and [5 of the forceps are slightly compressed until the end N3 of the handle 15 rests in the lowermost ratchet tooth H -as shown in Fig. 1 In this position, the clip 29 rests firmly in position between jaws H and 12 of the forceps, so that-it cannot be dislodged. The surgeon is now ready to sever the umbilical cordandapply the clip to the infant.
Upon further compression of the handles [4 and it, the handle 15 rides upward along the ratchet teeth H, the spring tension-of the flexible ratchet i6 preventing the return of handle 15. As the jaws H and 62 of the forceps move together,-blade3l' enters the slot 34 and the'charmel 24 of the upper jaw "it, severing the umbilical cord while simultaneously'the projection 36 passes through the hole tit-entering'theanvi-l 25 and is simultaneously bent over as shown-in Fig. "-4, to permanently lock the legs 36 and '3! 0f the clip 29. During the closing of jaws II and '12, the upper pin 26 enters the hollow 28 of the 'pin 21 as shown in Fig. l. The'ehdofthe umbilical cord is firmly compressed between the inner surfaces 39 and 4!! of-thelgs st and-e1 r'es'l'ie ctively of the clip'and to previitedge's ll and 42 ofthe clip trom' again severin the umbilical cord, I have rpunded the opposed longitudinal edges '43 and 4'4, so "as to provide a slight give orr'esili'enoy at the edges 4| "and i2, thus preventing injury to the u'rhloilie ail C'Orfl at this point.
' Numbers, l'e't'ters or'characters inay be placed along any portion 'o'fthe-cli'p '29 to provide positive identification- 0f the infant and the mother.
I prefErtQniaKe 'myclip of'very thin stainless meta-l which-can be easily sterilized and which will iiot-causeinjuiy, weightor irritation to the infant. Aftertheblipisapnlied, it remains upon the umbilical cord of the infant until it falls off of its own accord after healing.
In Fig. 7, I have shown a modified clip having opposed legs 45 and 46; the upper leg 45 has one edge 41 bent and overlaps the lower leg 45 which has asharp upper edge 48. When the clip is compressed by the jaws 50 and 5!, the umbilical cord (not shown) is severed by the sharp edge 48 and the sharp inside overlapping edge 49. v The umbilical cord -'is sealed and compressed between the inside faces of the upper and lower legs 45 and 46.
In Fig. 8, I have shown another modified clip comprising like upper and lower legs 52 and 53.
'The inner 's'urfac'es of the jaws 54 and 55, however,
are tapered in opposite directions, as shown so uponone side of legs 52 and 53 which will cause the umbilical cord to be severed on the inside sharp edges of the opposed legs of the clip and the umbilical cord will be compressed between the inside faces of l'eg's'52 and 53.
