SINGLE CLIP DISPOSABLE APPLICATOR Filed March 1, 1962 /0 FIG. 1

W m. x

IN VEN TOR.

Adolph M. Brown United States Patent 3,15%,379 SINGLE CL DlSYG-SABLE APPLXCATOR Adolph M. Brown, 9735 Wilshire Blvd, Beverly Hills, Calii, assignor of twenty percent to Ernest E. Wood and twenty percent to Rene G. Le Vaux Filed Mar. 1, 1962, Ser. No. 176,632 7 Claims. (Cl. 1-349) This invention relates to a device for use in the application of clips to efiect joinder of adjacent edges of tissue, such as skin, and the like, and it relates more particularly to a skin clip applicator which is of such construction and low cost as to enable sterilization and use for a single application.

In my copending applications Serial No. 10,595, filed February 24-, 1960, and entitled Means and Method for Suturing Wounds and Elements for Use in Same, now Patent No. 3,098,232, issued July 23, 1963, and Serial No. 130,630, filed August 10, 1961, and entitled Surgical Clip, disclosure is made of a clip and applicator in which a cartridge containing a multiplicity of clips may be loaded for repeated application in effecting skin closure or in an anastomosis for joining free ends of connective tissue or vessels. While a device of the type described finds excellent use in surgery and the like, the applicator is a rather complicated and expensive structure and maintenance of sterile conditions until the cartridge of clips has been used is sometimes difficult to achieve.

Thus, there is a need for a single clip applicator which is of such low cost and simple construction as to enable the applicator to be thrown away once the clip therein has been used, thereby to comprise a single use throv away applicator which can be initially sterilized.

It is an object of this invention to produce a clip applicator of the type described and it is a related object to produce a clip applicator which is simple in construction, which is easy in operation, which can retain a single clip in position of use, which can be sterilized when assembled as a package, with or without the clip therein, which is of low cost and therefore capable of economical and efiicient use as a throw-away applicator, which re-' tains the clip in position of use to be readily accessible to the elements to be joined, which is fully accessible for observation properly to position the clip for application, and which is effective to achieve clip application and closure in a simple and efiicient manner.

These and other objects and advantages of this invention will hereinafter appear and, for purposes of illustration, but not of limitation, embodiments of the invention are shown in the accompanying drawings, in which:

FIGURE 1 is an enlarged perspective View, taken from the bottom side, of the clip applicator with a clip in mounted position therein;

FlGURE 2 is a perspective View of one form of clip which may be used with the applicator of FIG. 1;

FIGURE 3 is a perspective view of the clip shown in FIG. 2 in closed position;

FIGURE 4 is a perspective view from the topside of the clip applicator shown in FIG. 1;

FIGURE 5 is a sectional view taken along the line 5-5 of FIG. 4;

FIGURE 6 is a sectional view taken along the line 6-6 of FIG. 4; and

FIGURE 7 is a perspective view of a modified form of clip which may be used in the applicators of FIGS. 1 and 4.

Referring first to the skin clip with which the applicator is intended to be used, reference can be made to the aforementioned copending applications for a more detailed description thereof. Briefly described, such skin or surgical clip comprises a clip of elongate, laterally spaced apart arms 10 and 12 interconnected at one end ice by a deformable cross arm or bail 14. The free ends of the arms are formed with spurs or prongs 16 extending laterally inwardly and downwardly from the end portions of the arms to a point or spicule intended to enter into the underlying tissue or skin when they are displaced in the direction towards each other while the spurs or spicules are in surface contact with the underlying skin or tissue. Thus the spurs or spicules engage into spaced apart portions of the skin or tissue to bring them together as the arms of the clip are continued to be displaced in the direction towards each other.

In the modification illustrated in FIGS. 16, the spurs or spicules extend inwardly and downwardly from the end portion of the spaced arms, the outer end portions of which are oifset inwardly from the lateral outer edges to provide shoulders. In the modification shown in FIG. 7, the spurs or spicules 16 extend inwardly and downwardly from a portion of the arms 10 and 12 spaced a short distance inwardly from the ends to provide stop shoulders 18 and 2% on each side of the prongs which limit the amount of entrance into the engaged skin or tissue.

The cross arm portion 14 is preferably located in the same plane as the arms 10 and 12. In the alternative, they can be formed with a slight upward curvature with the highest point at about the center to facilitate deformation or the clip from both open to closed position. Similarly the bail or cross arm 14 can be formed with lesser thickness at the center 22 so as to concentrate the bend in the central portion of the bail when the arms are displaced in the direction towards each other from open to closed position. The spicules or prongs can be of various dimensions depending upon the use to be made of the clip. As defined in the aforementioned copending applications, they may be dimensioned to have a length preferably greater than 0.005 inch up to 0.1 inch and pref erably about 0.25 inch.

The applicator, identified by the numeral 30, comprises a frame member formed of a structurally strong but deformable material having a pair of laterally spaced apart arms 32 and 34 and a bail or interconnecting cross arm 36 joining the laterally spaced apart arms at one end. At the opposite ends, the arms comprise clamping end portions wherein the end portions are spaced one from the other by an amount which is less than the width of the clip member adapted to be mounted therebetween. In the clamping end portions, the arms are formed with grooves 38 which extend inwardly from the forward edge for a distance which is slightly less than the length of the clip member and which extends laterally into the inner walls of the clamping end portions of the arms by an amount whereby the spaced relationship between the outer walls of the groove is slightly greater than the width of the clip. Thus the clip can be displaced endwise to be received in fitting relationship within the grooved end portion of the applicator with the down-turned prongs 1d projectingfrom the end portion of the applicator. When the applicator is adapted to be used with clips having the spurs or spicules spaced a short distance from the ends of the arms, as in FIG. 7, the length of the grooved portion will preferably correspond -to the length of the clip beyond the spurs or spicules.

In the preferred practice of this invention, instead of providing grooves 38, the end portions of the arms are dimensioned to be of lesser thickness than the remainder by an amount corresponding to the location of the groove with the grooved portion retained only at the base to extend crosswise of the clip arms at a level flush with the bottom walls of the end portions of lesser thickness so that the bail 14 of the clip can be received therein for support in position of use with the remainder of the clip arms being unobstructed from the underside. In effect,

i by an" amount slightly: greater than the width of the end -"POI'fiOIIE'Of thBGIiP adapted to lietherebetween when the 1 "bail 'ofrtheclip is receivediin the groove and which are fspacediorw'ardly from .the base of the; groove by an 7 amount slightly less than theplen'gth -of' theclipso that ""the abutr'he'ntsiwill be in position to engage the lateral L fedges bfZthe"clip'to eflect deformation from open to I closed position responsive to displacement of the clip 'a'rrns inthe direction towards each other. 'In this construc -"'tion,'i the clip member is retained in position of use: by "the" portion 'which:.is received with in the remaining *groove,-'while the major portion of. the clip is free of the "fapplicator to enable relative movement in a downward "directionas well'as endwise-movement to withdraw the "bail from the groove of theeapplic'ator when the clip has been deformed to closed position. Under these circum- 1 1 stances;- the .abutments 40 operate 'to stabilize the lateral .'-'position -of* the clip so thatthe=groove38 defined be- "tweenthe top wall '42'and the overhang 44' can extend "continuouslycrosswise of the applicator.

L Thus the 'abutments ="serveas stops to prevent excessive closure of' the inserted "clip me'mbers.

2*It is preferred to fabricate the applicator of plastic maiterial; since such "materials .are readily available. at low "cost? and inexpensively molded to the desired construc- '-"'tion'to:2provide.a' throw away'unit. It' can be easily sterilized orfmaintaineclinra sterile state when the-clip iisrnaintained in position of use thereinp In'practice, the Ficlip isin'serted with' the base of .theclip' received within the slotted'po'rtionfor support and with the down-turned spurs extending down'walrdlyifrom' between the clamping I end portions of 'the applicator,- as illustrated 'in-the drawtings. j Theassenibly can be sterilized in advance and then packaged in *a setrilized state for use.

This causes the. endportion' of theclip arms similarly tobe displac ed in thei direction toward'each'other whereby-the spicule penetr'ates i ntlo the underlying tissueifor' attachment to '4 a bring the spaced portions of the tissue together .as the applicatorandclip arms are further deformed totclosed position. Thus, the clip is deformed from open to closed position with the spaced portions of the tissue engaged 5 therebetwen. When in closed position, the applicator arms can be released forreturn to original position, if

formed of resilient-material, or otherwise to remain in 7 closed positionand the'applicator can be rearwardly displacedto freethe clip fronr'the'positioning' slot of the 10 applicator t lereby to leave the clip in closed orclamping position of use. T p

It will be apparent from the foregoing that I have pro- "vided a clip applicator-which is'capable-of singleuse for mounting a skin 'or'surgical' clip and for-the application of same to effect joinder of tissue. It will be understood that the applicatorsdescribed-can be; discarded after: a single use but'that it also may be r'eloaded,'if desired, with single clips to effectmultiple usage.

It Willbe understood that changes may be-made zin the details of construction,'arrangementand operation without'departing from; the spirit of'the invention, especially as defined in the following. claims.
