Abstract

A hand-operated applicator for use with surgical clips, such as wound clips, comprising a pair of elongate members, one of which is capable of axial movement within a longitudinal cavity in the other, and a pair of jaws projecting from the cavity resiliently biased into an open position and connected to the inner elongate member so that the said axial movement causes the jaws to close against the bias. Clips are fitted into the jaws, preferably from a magazine. The applicator can be made entirely from plastic material but it may be preferred to make the small jaw members from steel. The cost could be low enough to allow the applicator to be supplied pre-sterilised and thrown away after one operation.

Clips with which this invention is concernedv com,-

prise small, substantially V-shaped pieces of-metal or the like which may be deformedby moderateforce so as to cause the arms of the V' to come toget erand'to remain in thisdeformed position, thus clamping anartery or the like located between the arms of the V. Clips of this type will hereinafter be referred to as deformable clips or, simply clips.

-It is current surgical practice to use small,inert(e.g., of tantalum, stainless steel or silver).deformable metal clips, to holdtogether wound-edgesror to-clarnparteries before they are severed in: surgical operations. The clamping of arteries, for example, iscommonly performed by manually inserting adeformable clip in. a pair of sterile forceps, andthendeformingathe clip into its clamping position by means of the forceps. I

The forceps commonly used are precision; made in surgical quality stainless steel and have to be resterilised between surgicaloperations. 'li'hus they have a high initial cost plus the recurrent cost incurred-in,

successive sterilisations. Attempts to use disposable plastics forceps for this purpose have not proved entirely satisfactory, asitis difficultto make them sufficiently robust while maintaining. aesthetically acceptable to the surgicalprofession. The main limitationin streamliningthe design of the aforementioned plastics forceps resides in accommodating the large bending moments whichhave to. be wiflistoodibythearmsof the forceps. t I

.We have now devisedaan applicatorsuitable for use with clips of the type referredtoin which only compressive and tensilev stresses are generated in the activating members, thus. enabling a slimmer: design to'- be used, especially when constructedifromplastics,materials.

According to the present invention, an: applicatonfor use with a surgical clip of the type referred to comprises a pair of elongate members, one of which fits within an elongate cavity in the other and. is capable of.

axial movemnt therein, means for causing'relative" axial movement between the two members, and means'bywhich a pair of movable jaws are retainable within-said cavity with one end of each jawprotrudingfrom-the cavity, its other end being engagable withv the inner member so that the jaws execute alsimilar axialmovement therewith, the walls of 'thecavity being, provided with bearing surfaces adaptedto co-operate with corre sponding surfaceson-the jaws whereby thesaidrelative axial movement causes the jaws-to eometogetherin. a gripping motion.

The jaws may be permanently retained within-the cavity in permanent engagement with the inner member and, in-some embodiments, may-'be-formediintegrally. with it. Preferably the jawsare resiliently biassed into an open position sothatappliedrelative axial movement is only required in: the gripping, direction, the returnmovement being caused'by the-said bias.

This bias is conveniently achieved by theprovisionof a resilient member between the jaw members but remote fromtheirgripping surfaces.

The co-operating, surfaces of jaws andrcavity'may comprise inclined; planes, or tapers, *havingsimilar inclination to minimise frictional forcesbetweenthe'two.

. other fibres or filaments. The final choice of material Forexample, if the cavity is provided with an outwardly facing taper, the jaws may be closed by drawing them into the cavity, whereasin the case of a cavity having an inwardly facing taper the jaws may be closed by eitpelling them slightly from the cavity. It will be appreciated that either the jaws or the cavity along may be provided with a taper.

' Any suitable means may be used for causing relative axial movement between the two elongate members, the choice being largely dependent upon whether the device is intended to be hand or power operated. It will also depend on whether the design requires the inner member to be pulled or pushed to efi'ect closing of the aws.

. v The applicator may be constructed mainly or totally from plastics materials, two or three mouldings generallysufficing. Thesemay be adapted to interlock or may be secured together by some simple assembly technique, such as welding or riveting which is readily adapted to mass-production. However, it is possible to form our applicators as one piece plastics mouldings.

Suitable plastics materials include polypropylene, polystyrene, polyethylene, and poly(4-methyl pentene- 1)and their copolymers, A.B.S. copolymers, and polyarnides with or without reinforcement, such as glass or will depend upon the stresses liable to be generated in .thezparticular partof the device for which itis used; for example, polypropylene is very suitable for any part .whichis required: to withstand repeated flexure, whereas a reinforced material, e.g., glass fibre filled nylon is desirable if plastics materials are usedfor the jaws. When. this is done, itis possible toformthe inner member and: two jaw members from a single piece of plastics material.

when separate jaw members are used, they may be formed, for example, with inwardly pointing hook-like ends-adaptedto be located within the cavity in the outer member so as to engage with recesses in the inner member which enable them to pivot andthus accom- Lbe sterilised between operations, the remainder being disposable. This may represent a worthwhile saving in sterilisation time, as the jaws are small and may be readily designed to be free of narrow crevices in which bacteria'andthe like might lodge. However, since the clips used may be assmall as 4 mm in length, the jaws need be only some mm long and 6 sq.mm. in crosssection and are readily mass-produced. Thus, even when constructedfrom, for example, surgical quality stainless steel their-cost may be small compared with the cost of repeated re-sterilisation, so that plastic applicators with metal jaws constructed according to our invention may be cheap enough tobe disposable.

It is, of course, within the scope of our invention that the whole applicator may be constructed of surgical quality stainless steel orthe like to enable it to be resterilised many times.

1 Applicators according to our invention may be made in-a very slim form, even in plastics materials, and may be designed to be used without hand movement across the line of sight, unlike forceps and other applicators of the scissors type. Thus it is possible for our applicators to allow access to very narrow cavities such as are frequently encountered in, for example, brain surgery and to cause a minimum of obstruction of the surgeons vision.

It will be appreciated that when our applicators are produced as a single plastics article, e.g., a one-shot moulding, the article preferably comprises two elongate portions which are adapted to co-operate to define a cavity in which an inner member may move axially- Such an article may comprise a central elongate inner member, flanked by a pair of elongate cavity-forming members which are capable of co-operating to form an outer member which encloses the said inner member, the three members lying substantially parallel over most of their lengths, one end of each member issuing from a common, integral junction, so that the article has a generally tri-furcated appearance.

The cavity-forming members are preferably designed so as to snap together by means of co-operating grooves, ridges, studs or like expedients which make use of the natural resilience of the plastics material, to facilitate assembly of the applicator. If the jaws of the applicator are also to be of plastics material, these may be formed integrally with the rest of the device. When this is done, the plastics material must be chosen so that it possesses sufficient rigidity for the jaws to deform the clip. It has been found, for example, that nylon filled with 40 percent by volume of glass fibre is a suitable material for such applicators.

In order that the invention may be more clearly understood, three embodiments of our invention will be described, by way of example only with reference to the accompanying drawings of which:

FIG. 1 is a sectional elevation of one form of applicator;

FIG. 2 is a partly cut-away isometric view of a second form of applicator;

FIG. 3 is an isometric view of a third form of applicator of one piece construction;

FIG. 4 is a section through the assembled applicator of FIG. 3 on the line IVIV; and

FIG. 5 is an enlarged view of the end of a jaw of one of our applicators.

Like reference numberals are used throughout to designate like parts.

Referring to FIGS. 1 and 2, outer elongate member 1 is formed from polypropylene and provided with internal cavity 2 within which inner elongate member 3, also formed of polypropylene, is a sliding fit. Inner member 3 is provided near one end with recesses 4, which accommodate hook-like extremities 5 of metal jaws 6. Beyond recesses 4 but at the same end of inner member 3, integral V-shaped protuberance 7 serves to bias jaws 6 resiliently towards the inner surfaces of cavity 2. Co-operating surfaces 8 of jaws 6 and cavity 2 are provided with matching inclined planes which, in the embodiment shown in FIG. I, serve to force jaws 6 together when inner member 3 is moved towards the left of the drawing, and in the embodiment shown in FIG. 2, movement of member 3 towards the right has a similar effect.

The end of inner member 3 remote from jaws 6 protrudes past the cavity-defining part of outer member 1. In the case of the embodiment shown in FIG. 1, a U- shaped band of propylene 9 links inner member 3 to outer member 1. Hand pressure applied across the limbs of the U, as indicated by arrows A, causes the tips of jaws 6 to come together in a gripping action as indicated in broken lines. In the case of the embodiment shown in FIG. 2, the outer extremity of inner member 3 is secured, e.g., by bonding or riveting, to the end 10 of polypropylene loop 11 which is formed integrally with outer member 1. Hand or finger pressure applied across loop 11, as indicated by arrows B, has the effect of closing the tips of jaws 6 in this embodiment.

Referring to FIG. 3, the applicator illustrated is of the same general form as that of FIG. 2 with the exception that it comprises a single piece of nylon reinforced by 40 percent by volume of glass fibre to impart the necessary regidity to the jaws 6. However, outer member 1 comprises two U-sectioned members 1A and 1B which may be snapped together as shown isometrically in broken lines in FIG. 3 and in section in FIG. 4, to form cavity 2 in which inner elongate member 3 may slide. Cavity forming members 1A, 1B are retained in position by the snap action provided by the co-operation of ridges 12, 13 on their inner surfaces. Members 1A and 1B are located near the extremities of elongate members 11 which serve the same purpose as loop 1 l in the embodiment illustrated in FIG. 2.

In the embodiment shown in FIG. 3 elongate members 11 and inner member 3, being part of a single piece of nylon, are joined integrally through bridging member 10. Jaws 6 are formed integrally with inner member 3 being biassed into an open position by the natural resilience of the material. When fully assembled, this embodiment operates in a similar fashion to that shown in FIG. 2, with the exception that the bearing surfaces 8 of cavity 2 are not provided with tapers. It will be appreciated however, that it is possible for form applicators of this general type, but having detachable metal jaws by omitting the jaw members from the end of member 3 and substituting them by recesses 4 and V-shaped protruberance 7, as shown in FIG. 2.

The inner, or gripping, surfaces of the jaws are preferably provided with longitudinal grooves to facilitate alignment of the clip during application. Because of the scale of the drawings, these grooves are not shown in FIGS. 1 to 3; but they are illustrated in FIG. 5 which is a scrap view of one jaw on a much enlarged scale. Referring to FIG. 5, jaw 6 is provided on its inner surface with longitudinal groove 14 into which one leg of an undeforrned V or U-shaped clip may be fitted. The jaw illustrated in FIG. 5 is further provided with a transverse groove 15 designed to accommodate a protrusion or like discontinuity in the leg of the clip so as to locate it in a longitudinal direction with respect to the jaws. Instead of groove 15 it is possible to provide a local construction in the width of groove 14 which will cooperate with a suitably positioned constriction in the leg of the clip. Clips having such protruberances or constrictions are described and claimed in our copending patent applications.

In use a V or U-shaped clip 12 (see FIG. 1) of stainless steel or other surgically acceptable material is fitted into grooves 14 (see FIG. 5) in the inner surface of jaws 6. Clip 12 is then arranged to straddle an artery or the like and deformed into a gripping or clamping position by operation of the jaws of the applicator as described above. On release of pressure from the appropriate part of the applicator, jaws 6 open under the bias of resilient member 7 or under the influence of the natural resilience of the material to enable them to receive another clip.

Although the invention has been illustrated by reference to metal artery clips, it may be used equally well with clips of other surgically acceptable materials.

As previously mentioned, applicators according to our invention may be supplied pre-sterilised and discarded after use. Sterilisation may be conveniently performed after packing the applicators in an air-tight plastics bag, by mean of irradiation or ethylene oxide treatment.
