Abstract
Abstract This invention relates to a surgical clip for cutaneous suture, wherein it successively comprises, starting from the centre of the clip and on each side of the plane of symmetry of the clip, a rectilinear branch, a first bend with concavity facing the skin into which the clip must be engaged, a second intermediate bend with convexity facing the skin and a third bend with concavity facing the skin, this third bend extending by an end leg terminating in the point of the clip and which is inclined by an angle of about 45° with respect to the general direction of extension of the clip. The invention also relates to a tool for applying said clip.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
136 words
A surgical clip for cutaneous suture constituted by a piece of wire made of a rigid but deformable material, particularly of metal, symmetrical with respect to a plane, terminated by two points and presenting, in the open state, a sinuous shape, wherein it successively comprises, starting from the centre of the clip and on each side of the plane of symmetry of the clip, a rectilinear branch, a first bend with concavity facing the skin into which the clip must be engaged, a second intermediate bend with convexity facing the skin and a third bend with concavity facing the skin, this third bend extending by an end leg terminating in the point of the clip and which is inclined by an angle of about 45° with respect to the general direction of extension of the clip.
Claim 2
Dependent Claim
136 words
A surgical clip for cutaneous suture constituted by a piece of wire made of a rigid but deformable material, particularly of metal, symmetrical with respect to a plane, terminated by two points and presenting, in the open state, a sinuous shape, wherein it successively comprises, starting from the centre of the clip and on each side of the plane of symmetry of the clip, a rectilinear branch, a first bend with concavity facing the skin into which the clip must be engaged, a second intermediate bend with convexity facing the skin and a third bend with concavity facing the skin, this third bend extending by an end leg terminating in the point of the clip and which is inclined by an angle of about 45° with respect to the general direction of extension of the clip.
Claim 3
Dependent Claim
39 words
The surgical clip of claim 1, wherein the clip has the general form of an obtuse-angled V and it comprises a rounded central web, at the location of the apex of the V, which joins the two rectilinear branches.
Claim 4
Dependent Claim
109 words
A tool for applying the surgical clip for cutaneous suture of claim 2, comprising an anvil member on which is applied the central part of the clip and mobile presser coming into contact with the lateral parts of the clip in order to bend them around the anvil, comprising in its face turned towards the anvil member, a recess whose width is greater than that of the anvil member and defining, on either side, bearing faces coming into contact, in the first place, in the course of the movement of deformation of the clip around the anvil member causing closure thereof, with the outer third bends of the clip.
Claim 5
Dependent Claim
25 words
The surgical clip of claim 1, wherein the clip has a flat shape in the open state and its two rectilinear central branches are coaxial.
Claim 6
Dependent Claim
75 words
A tool for applying the surgical clip for cutaneous suture according to claim 4 comprising in its face turned towards the anvil member, a recess whose width is greater than that of the anvil member and defining, on either side, bearing faces coming into contact, in the first place, in the course of the movement of deformation of the clip around the anvil member causing closure thereof, with the outer third bends of the clip.
Claim 7
Dependent Claim
112 words
A tool for applying the surgical clip for cutaneous suture of claim 1, comprising an anvil member on which is applied the central part of the clip and a mobile presser coming into contact with the lateral parts of the clip in order to bend them around the anvil, wherein it comprises, in its face turned towards the anvil member, a recess whose width is greater than that of the anvil member and defining, on either side, bearing faces coming into contact, in the first place, in the course of the movement of deformation of the clip around the anvil member causing closure thereof, with the outer third bends of the clip.
Claim 8
Dependent Claim
40 words
The tool of claim 6, wherein the recess of the presser has a rectangular shape, it is defined by a bottom and two lateral sides, the distance between these lateral sides being greater than the width of the anvil member.
Claim 9
Dependent Claim
89 words
The tool of claim 6, wherein the recess of the presser comprises an upper or inner part of trapezoidal vertical section which is defined by a upper horizontal bottom and two inclined lateral faces, and a lower or outer part of rectangular vertical section which comprises two outwardly extending horizontal faces, constituting the upper faces of the lower rectangular recess and which are themselves extended downwardly by vertical lateral faces opening out in the lower face of the presser which is consequently limited to two horizontally extending, lateral parts.
Claim 10
Dependent Claim
55 words
The tool of claim 8, wherein the two horizontal lower faces of the presser are spaced apart from each other by a distance such that, during the movement of the presser towards the anvil member, they come into contact with the apices of the outer third bends of the clip flat on the anvil member.
Claim 11
Dependent Claim
58 words
The tool of claim 9, wherein the width of the large lower base of the upper trapezoidal part of the recess, i.e., the distance between the edges of join between the inclined lateral faces and the horizontal faces, is equal to or slightly larger than the distance between the apices of the two first blends of the clip.
Claim 12
Dependent Claim
48 words
The tool of claim 9, wherein it allows, by the width of the presser and the trapezoidal shape of its upper part, an adjustment of the closure of the clip depending on the nature of the skin to be sutured, avoiding the use of clips of different sizes.
Claim 13
Dependent Claim
58 words
The tool of claim 8, wherein the width of the large lower base of the upper trapezoidal part of the recess, i.e. the distance between the edges of join between the inclined lateral faces and the horizontal faces, is equal to or slightly larger than the distance between the apices of the two first bends of the clip.
Claim 14
Dependent Claim
48 words
The tool of claim 12, wherein it allows, by the width of the presser and the trapezoidal shape of its upper part, an adjustment of the closure of the clip depending on the nature of the skin to be sutured, avoiding the use of clips of different sizes.
Claim 15
Dependent Claim
48 words
The tool of claim 8, wherein it allows, by the width of the presser and the trapezoidal shape of its upper part, an adjustment of the closure of the clip depending on the nature of the skin to be sutured, avoiding the use of clips of different sizes.
