Definitions

• the present invention relates to an instru ⁇ ment of cosmetic surgery of the nose in order to modify the shape of the nose (rhinoplasty), more particularly to remove an osteocartilaginous bump and to perform a lateral osteotomy of the bones of the nose.
• the cartilage which extends from half the nose to the tip of the nose.
• the bone and cartilage are between the skin on the outside and the lining of the nose on the inside.
• the septum is the cartilage that supports this arch in the center.
• a nose bump is therefore made up of a bony half and a cartilaginous half.
• the sections of these two halves of the hump are practiced by two different types of instruments: a) for cartilage we use scissors, whose action therefore stops at the bone.
• a straight chisel and a hammer are used, which makes it possible to advance the chisel to remove the remaining bone part of the hump of the nose.
• the object of the invention is therefore to propose an instrumentation the implementation of which makes it possible to obtain more satisfactory results, which is either work less difficult and moreover of a lower cost than that of the instrumentation used until now.
• the cosmetic surgery instrumentation of the nose comprises: - a pair of scissors intended for removing the bump and having cutting blades with concave cutting edges facing each other and adapted to the anatomy of the bump,
• the pliers replace the straight chisel and the hammer while allowing the making of much less difficult and more satisfactory lateral cuts than the cuts previously made.
• the ex ⁇ end of one of the cutting blades of the pair of scissors is provided with a transverse lug directed towards the end of the second blade.
• This lug can be either supported on the upper end of the bridge of the nose, or pressed into one of the lateral bones of the nose in order to correctly fix the location of the scissors before cutting.
• the blades and cutting edges of the scissors may also have a curvature in a plane perpendicular to the general plane of the pair of scissors.
• one of the blades of the osteotomy forceps has an edge of concave cut, while the second blade is provided with a convex edge.
• Figure 1 is a top view, substantially to scale, of an embodiment of the pair of nose hump ablation scissors.
• Figure 2 is a perspective view illustrating a first embodiment on the nose of a patient of the pair of scissors of Figure 1, to remove the bump.
• Figure 3 is a perspective view with cutaway illustrating a second embodiment of the pair of scissors of Figure 1 for removing the bump.
• FIG. 4 is a top view, substantially to scale, of a second embodiment of the pair of scissors of FIG. 1.
• Figure 5 is a top view substantially on a scale of pliers with cutting blades, adapted to the lateral osteotomy of the nose after removal of the bump.
• FIG. 6 is a view in longitudinal elevation along arrow F of the clamp of FIG. 5.
• Figure 7 is a perspective view illustrating the implementation of the forceps of Figures 5 and 6 for the lateral osteotomy of the nose of a patient after removal of the bump.
• Figure 8 is a partial perspective view of an alternative embodiment of the forceps of Figures 5 to 7.
• the instrumentation for cosmetic surgery of the nose illustrated in the drawings comprises a pair of scissors 1 ( Figures 1 to 3) and pliers 2 with cutting blades ( Figures 5 to 7) adapted respectively to each of the two rhinoplasty operations described above.
• the scissors 1 comprise two handles 2, 3 articulated around an axis 4 and the ends of which constitute respective cutting blades 5, 6 with concave cutting edges 7, 8 opposite, adapted to the anatomy a bump 9 on the nose 11 of a patient P (of a patient) which must be removed.
• the hump 9 is composed of a cartilaginous part 9a and a bone part 9b.
• the cutting edge 7 of the blade 5 is advantageously composed of two rectilinear sections 7a, 7b extending in a slightly concave general direction. Section 7b, the furthest from the articulation axis 4, can be extended as shown by a transverse lug 10 directed towards the rounded end 6a of the second blade 6, and connected by a rounded end 5a to the rest of the blade 5.
• the cutting edge 8 of the blade 6 forms a regular concave quickly opposite the concave edge 7 and substantially along the same length.
• the geometry of the cutting edges 7, 8 can vary appreciably from that shown in the drawings, while remaining adapted to the particular anatomy of the person to be operated on.
• the two sections 7a, 7b can be replaced by a concave circular section.
• the cartilaginous part 9a and the bone part 9b of the nasal hump 9 can be cut in a single operation, without variation in the cutting axis. between the bone part 9b and the cartilage part 9a.
• the surgeon chooses from a set of scissors 1 of different dimensions annuities, the one that is best suited to the anatomy of the nose of the person whose lump 9 is to be removed.
• the spacing between the two edges 7, 8, before the cut is determined by the shape of the nose 11 of the patient P at the place where the section is to be performed.
• the lug 10 is placed in abutment on the nasal bridge at the base of the bump 9, at the level of the eyes of the patient P and determines the place where the cutting must stop.
• the surgeon introduces the ends 5a, 6a, of the blades 5, 6 into one of the patient's nostrils, namely the right nostril for a right-handed surgeon (FIG. 2), with the branches 5 and 6 under the skin of the nose and against bone and cartilage.
• the blades 5, 6 are removed from the nose 11 and the bump 9 extracted by the nostril.
• the pair of scissors 1 which has just been described is capable of various variant embodiments. Thus, as already indicated, while retaining the principle of scissors with curved blades, these can have different shapes and dimensions depending on several elements, in particular the volume of the patient's bump and the strength of the bone. Similarly, the lug 10 can be omitted, and at least one of the cutting edges 7, 8 can be provided with micro-teeth, which prevent the blades from sliding on the nasal bone.
• FIG. 4 Another possible variant is illustrated in FIG. 4: according to this, the sleeves 12, 13 of the scissors 14 are articulated on an axis 15 with the free rounded ends 16a, 17a of their cutting blades 16, 17.
• the axis of rotation 15 is disposed at the naso-frontal angle.
• the blades 5, 6 or 16, 17 may have a slight curvature in a vertical plane, that is to say in a plane perpendicular to the plane of FIGS. 1 and 4, to then obtain a slightly concave nose edge profile line.
• cutting blades 5, 6, 16, 17 are rounded, avoids weakening the skin of the nose, as is the case with usual straight scissors, like those used in the prior art.
• the rhinoplasty instrumentation targeted by the invention also comprises a clamp 18 (FIGS. 5 to 7) adapted for the lateral osteotomy of the bones of the nose, after cutting of the hump 11, in order to bring the two lateral parts of the nose 11 together.
• the clamp 18 consists of two sleeves 19, 21 articulated around an axis 22 and which are provided with respective cutting blades 23, 24 having respec ⁇ tive edges 25, 26.
• the blades 23, 24 and their edges 25, 26 each have a double curvature in two perpendicular planes, namely the horizontal plane and the vertical plane, the cutting edge 25 being further concave while the cutting edge associated 26 is convex.
• FIG. 5 shows the curvature of the blades 23 and their edges 25, 26 in the horizontal plane, while their respective curvatures in the vertical plane are illustrated in FIG. 6.
• the curvatures of the cutting edges 25, 26 being adapted to the clean bone shape of the nose, right forceps and left forceps are therefore necessary.
• Each cutting blade 23, 24 has between its articulation axis 22 on the other blade and the curved part constituting the cutting edge 25, 26, a straight part
• a straight line D passing through the ends of the curved part 25 or 26 forms, with a straight line D 1 passing through the straight part 27, an angle A of between 5 and 90 °.
• the cutting edges 25, 26 can be provided with micro-teeth (not shown).
• the free ends of the blades 23, 24 can be provided with a flat point 28 constituted by a pad, arranged in the extension of the corresponding cutting edge 25 or 26.
• the pad 28 can either be attached to the tip of the cutting blade, or come in one piece with it.
• the cutting operation is carried out for each lateral bone with the corresponding pliers.
• one or two flat end pads 28 on the cutting blades facilitates the introduction of these between the skin and the bone on the one hand, and between the bone and the mucosa on the other hand , by promoting the separation of soft tissues in contact with the bone.
• the surgeon After osteotomy of the two lateral bones of the nose by forceps such as 18, the surgeon is able to reconstruct the nasal profile by moving the severed lateral parts of the nose to the desired level to replenish the nose from the front.
