  • -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.
  • 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,
  • 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.
  • 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.
  • the jaws are 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.
  • 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.
  • 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.
  • jaw members 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.
  • 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.
  • 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.
  • the whole applicator may be constructed of surgical quality stainless steel orthe like to enable it to be resterilised many times.
  • 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.
  • the article 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.
  • 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.
  • 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;
  • FIG. 5 is an enlarged view of the end of a jaw of one of our applicators.
  • 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.
  • inner member 3 remote from jaws 6 protrudes past the cavity-defining part of outer member 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 causes the tips of jaws 6 to come together in a gripping action as indicated in broken lines.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • An applicator for use with a surgical clip which comprises inner and outer elongate members, one of said elongate members fitting within an elongate cavity in the other and being capable of axial movement therein, means for causing relative axial movement between the two members and a pair of jaws located within said cavity with one end of each jaw protruding from the cavity, the other end of said jaw being engageable with the inner member so that the jaws execute a similar axial movement therewith, the walls of the cavity being provided with bearing surfaces which axially slidably cooperate with corresponding surfaces on the jaws whereby the said relative axial movement causes the jaws to come together in a gripping motion, the said means for causing relative axial movement between the elongate members comprising a loop-like extension of only the outer member disposed remote from the jaws, said extension comprising a pair of outwardly bowed, resilient limbs of the outer member which straddle the inner elongate member, the outer ends of the limbs and the outer end of the inner member
