Definitions
- the present invention relates to a milk ligation clip.
- the lettuce clips are used in slaughterhouses to seal the moss and prevent the contents of the belly from being spilled when the mussel is cut.
- Known clips disclosed for example in AU 38 423-78 or NZ 184817, generally comprise two parts connected by a film hinge at one end and provided at the other end of a closure system.
- the latter protrudes outside the two parts, and comprises for example a harpoon on one of the parts, arranged to snap into a housing formed on the other part.
- Both parts have teeth that are formed on legs extending obliquely rearward.
- the rows of teeth interpenetrate, and all the teeth extend in the same direction.
- the present invention aims to further improve the ligation clips of the herbarium.
- the invention thus relates to a ligation clip made of a single piece molding material, having two parts articulated at one end by a film hinge, and having at the other end a closure system, the parts with teeth coming to grip the foam when the clip is closed, a greater longitudinal dimension of the clip measured from the film hinge to the closure system being less than 45 mm, or even less than 42 mm, better less than 40 mm.
- the largest longitudinal dimension is the outer dimension of the clip, including the film hinge and the closure system.
- the reduced size of the clip limits the thrust force for its implementation and the risk of snagging on the surrounding tissues.
- the clip is configured to slide along the meadow, especially unidirectionally, that is to say that the effort to exert to slide in one direction is different from the effort to exercise in the other direction.
- a larger transverse dimension of the clip may be greater than 30 mm, or even greater than 35 mm and / or less than 45 mm, for example of the order of 40 mm about. This larger transverse dimension is measured perpendicular to the largest longitudinal dimension.
- the shape factor of the clip corresponding to the ratio of its largest transverse dimension over its largest longitudinal dimension, may be greater than 0.6, or even greater than 0.7, 0.8, 0.9 or better. greater than 1, or even greater than 1.1.
- the clip thus has a shape facilitating its sliding along the meadow.
- the closure system can be disposed inside the two parts of the clip, thus not protruding outwardly.
- the clip when viewed from the front, may have, on each of the parts, a widening above a gripping surface of the clip on which the user can place his fingers to close the clip.
- This gripping surface can be ribbed. The manipulation and closing of the clip are facilitated.
- These gripping surfaces on each of the parts are not arranged directly on the closure system, which may thus be free of protruding tongue.
- the two parties can define, when the clip is closed, an interior space to accommodate the meadow. This space can make it possible to avoid driving the foam to the closure system when the clip is closed.
- the space may be provided at least partially between the teeth, for example between two successive teeth on one leg and / or between two opposite teeth, each disposed on one of the two parts of the clip.
- the section defined by this space when the clip is observed flat, from above, is preferably greater than 0.5 cm 2 , to be sufficient to accommodate the empty and compacted mite between the teeth.
- the teeth closest to the hinge may be further apart than other teeth further away from the hinge.
- the invention thus makes it possible to create dead spaces which can partially house the meadow.
- the presence of these dead spaces does not prevent the teeth from exerting pressure on the moss and having an anti-return action.
- the minimum spacing between two teeth respectively belonging to the two parts may for example vary between 0 mm and 5 mm, when the clip is closed.
- a first spacing between two facing teeth may be less than a second spacing between two other teeth facing when the clip is closed.
- Two other facing teeth, different from the teeth defining the first and second spacing, may define a third gauge greater than the first and second spacings.
- Each part may have less than five teeth facing the other party.
- the teeth of one part can be exactly in front of the teeth of the other part when the clip is closed, or be shifted.
- Two adjacent teeth of one part may be connected by a concave edge towards the other part.
- the space between the two edges facing the articulated parts can grow while moving away from the closure system, which tends to avoid chasing the foam when closing the clip, to prevent it stands in front of the closing system.
- Both parts have support legs on which the teeth are formed.
- Each portion may for example have between 1 and 3 such carrier lugs carrying teeth.
- the number of teeth on each leg is for example between 1 and 5, better between 2 and 5.
- Each part may have three teeth, for example.
- the support legs can be oriented obliquely backwards, relative to the sliding direction of the clip on the meadow.
- the support legs may flex when the teeth are pushed back by the moss.
- the inclination of the support legs tends to prevent the clip from going down when it is up to the belly.
- the clip may comprise at least one additional lug, or even two additional lugs, oriented (s) obliquely rearward, on each of the parts between the support lug carrying the teeth and the film hinge. Such an additional lug tends to push the lather between the teeth. Such an additional lug may be devoid of teeth. These additional lugs allow to exert pressure on the moss but are not aggressive and therefore reduce the movement of the clip on the meadow. They can be relatively rigid. They also contribute to the sliding with non-return of the clip and to reduce its size.
- a tooth support tab and an additional tab exert thrusts in different directions on the clip.
- the clip may be devoid, on its outer surface, when closed and observed from above, closing system forming a projection. This avoids when the clip is moved along the meadow, to hang surrounding tissues, so the risk of damage to the clip and tissues and we also get a reduction in the effort of setting up.
- the closure system may be disposed within the clip.
- the closure system can be closed irreversibly.
- the weight of the clip may be less than or equal to 4 g.
- the invention makes it possible to produce a clip that is both effective and economical, with relatively little material.
- the clip may be molded in a polyolefin, for example polypropylene. The use of such a material is possible due to the rigidity of the clip related to its shape. The relatively short teeth are compatible with the use of such a material, which is not the case, to the knowledge of the applicant, known clips.
- the clip may be made by bi-injection of plastic material, which may contain at least one ferromagnetic element, for example near the closure system.
- the clip can be packaged in a non-sterile manner.
- the invention also relates to a ligation clip made of a single piece by molding of material, comprising two parts hinged at one end by a film hinge, and comprising at least one another end a closing system, the parts having teeth coming to grip the meadow when the clip is closed, the two parts defining, when the clip is closed, an interior space to accommodate the meadow, the closure system being integrated into the clip and not protruding outward.
- a ligation clip made of a single piece by molding of material, comprising two parts hinged at one end by a film hinge, and comprising at least one another end a closing system, the parts having teeth coming to grip the meadow when the clip is closed, the two parts defining, when the clip is closed, an interior space to accommodate the meadow, the closure system being integrated into the clip and not protruding outward.
- a clip is thus devoid of protruding tongue.
- the invention also relates to a ligation clip made of a single piece molding material, having two parts articulated at one end by a film hinge, and having at the other end a closure system, the parts comprising elements coming to grip the lather when the clip is closed, the clip comprising at least two elements configured to push the lather in different directions, once the clip closed, namely towards the median plane and substantially perpendicular to that for one of the elements and in a direction making a non-zero angle with the first, for example more than 30 °, for the second.
- the first element is for example the support bracket of the teeth defined above and the second the additional bracket mentioned above.
- the invention also relates to a ligation clip made of a single piece by molding of material, comprising two parts hinged at one end by a film hinge, and comprising at least one another end a closing system, the parts having teeth coming to grip the lather when the clip is closed, said teeth being spaced apart from a median plane of the clip when the latter is closed, or exceeding it by a smaller distance or equal to 2 mm, especially when the teeth are staggered.
- the spacing of the teeth or their low interpenetration reduces the forces exerted on the foam and facilitates the sliding of the clip.
- the subject of the invention is also a process for ligation of the meadow of a ruminant, bovine or ovine, in which a clip as defined above, which is slid on it, towards the belly.
- the dimensions of the clip can be adapted according to the animal, cattle or sheep.
- the dimensions of the clip may be as defined above.
- For a sheep they may be proportionally slightly lower, given the smaller size of sheep compared to cattle.

- FIG. 8 is a bottom view of the clip of FIG. 7, and
- FIGS 9, 9a and 10 are views respectively from above and below the clip of Figures 7 and 8 in the closed position.
- the clip according to the prior art represented in FIG. 1, comprises two parts articulated to one another around a geometrical axis of rotation R thanks to a film hinge 13. These parts include a closure system on the side opposite to the film hinge and rows of teeth that interpenetrate when the clip is closed.
- the clip 10 according to the invention shown in Figures 2 to 6, is molded in one piece of a thermoplastic material, for example a polyolefin, for example polypropylene.
- the clip 10 has two parts 11 connected at one end by a film hinge 13, and provided at the other end with a closure system for closing the clip on the foam.
- the closure system comprises a harpoon 15 on one of the parts and the other part comprises a housing 16 in which the harpoon can snap at the end of the bringing together of the two parts 11 against each other. 'other.
- the closure system can not be reopened after the latching of the two parts, given the presence of the branches 15a of the harpoon 15 which abut against the edge 16a of the housing 16 facing the other part.
- housing 16 and the harpoon 15 are contained within a space delimited by peripheral walls 17 of each of the parts.
- the peripheral walls 17 define a larger longitudinal dimension L of the clip and a larger transverse dimension T of the clip.
- L may be of the order of 39 mm and T of the order of 38.7 mm, in an exemplary embodiment.
- the clip internally comprises two tabs 18 extending obliquely rearwardly from the front face 20 of the clip.
- the angle with which the tabs 18 extend rearwardly, with respect to a median plane M of the clip is for example about 45 °.
- the tabs 18 have at their rear end a return 19 which extends perpendicularly to the median plane M of the clip, and on which are formed teeth 25.
- the teeth 25 are interconnected by an edge of the return 19 which is concave towards the other part.
- the teeth 25 are relatively short, their length /; being for example between 1 mm and 3 mm and their width / ? between 1 mm and 3 mm.
- the maximum thickness e of the teeth, measured along an axis parallel to the axis R of the joint, is for example between 0.5 mm and 2 mm.
- the edge 27 extending between the teeth 25 and the closest to the film hinge 13 is narrower, in the example considered, than that 30 located between the teeth furthest from the film hinge 14.
- Each lug 18 may comprise, as illustrated, three teeth 25, the interval ii between the teeth 25 furthest from the hinge 13 being for example of the order of 4 mm and that i 2 between the nearest teeth 25 being for example of the order of 5 mm.
- the spacing d of between the tops of the teeth opposite one another is for example between 0 and 4 mm.
- the tabs 18 and 40, and in particular the teeth 25 and the edges 27, 30, define an interior space E to receive the meadow and avoid chasing it to the closure system when the clip is closed.
- an internal partition 16b separates the closure system from the interior space E. This partition can prevent the foam interferes with the closure system.
- the clip 10 also has two tabs 40 each having an arcuate shape, which extend from the front face 20 of the clip obliquely rearward.
- the tabs 40 have at their rear end a return 42 which extends generally perpendicular to the axis R of the joint and which is directed towards the central region of the clip.
- This return 42 defines an arcuate edge, concave towards the interior space E.
- the support lugs 18 and the additional lugs 40 exert thrusts in different directions on the clip, namely respectively directions illustrated by the arrows Fi and F 2 .
- the hinged portions 11 define on their opposite faces 50 gripping surfaces 51 which may comprise, as illustrated, ribs 52.
- the outer shape of the clip may be devoid of protruding reliefs so as to reduce the risk of attachment of the clip on tissues surrounding the meadow.
- the clip 10 may have, when viewed from above, a rounded shape, with for example two cylindrical portions 55 adjacent to the closure system and two other cylindrical portions 54 adjacent to the joint.
- the clip further comprises ribs 60 extending transversely to the parts 11 and the tabs 18, so regidifer them.
- the clip of FIGS. 7 to 10 also differs from the clip of FIGS. 2 to 6 in that the internal partition 16b extends only on the side of the housing 16, and not on the side of the harpoon 15.
- the ends of the teeth 19 of the legs 18 of each of the parts 11 lie on the same straight line, the two straight lines being substantially parallel, as illustrated in FIGS. 2 to 6, or not, as illustrated in FIGS. 7 to 10. They may in this case form between them an angle CC, for example between 15 and 25 °, for example 18.2 ° value in the example shown.
- the spacing di, d 2 , d 3 between two opposite teeth may increase when approaching the hinge, as shown in Figure 9a, when the clip is closed.
- the shape of the articulated parts and the shape of the teeth can be modified.
- the clip may comprise an RFID device or a metal insert or may also receive during molding a metal compound, in particular by bi-injection.
- the cavities 16 can be used to house this device, but depending on the type of device used, it can be placed elsewhere, such as for example in the form of a wire in the outer part of the clip.
