Rhinoplasty instruments

Abstract

Instruments including a pair of scissors ( 1 ) for removing the bump from an aquiline nose, wherein the scissors have cutting blades ( 5,6 ), with mutually facing concave cutting edges ( 7,8 ) matching the shape of the bump, as well as a clamp with two cutting blades each having a double curvature in two perpendicular planes so that the clamp fits the lateral bones of the nose. The clamp enables lateral osteotomy of the nose once the bump has been removed by means of the scissors ( 1 ), whereby the surgeon can reconstruct the shape and profile of the nose. The number of instruments needed may thus be reduced considerably relative to the prior art, while the reliability, accuracy and safety of the operation may be substantially enhanced.

What is claimed is:  
     
       1. Instrumentation kit for plastic surgery of the nose comprising: 
       a pair of scissors for removing an osseocartilaginous bulge from the nose, the pair of scissors having a pair of cutting blades with concave cutting edges which face each other and further having a shape that corresponds to the anatomy of the bulge, each cutting blade of said pair of cutting blades having a distal end, the pair of scissors lying in a horizontal plane;  
       and a cutting tool for performing lateral osteotomy of the nasal bones, the cutting tool having two cutting blades, each cutting blade of the cutting tool having a distal end, at least one curvature in one of the horizontal plane and a vertical plane, each cutting blade of the cutting tool having a shape that corresponds to the anatomy of the lateral bones of the nose.  
     
     
       2. Instrumentation kit according to  claim 1 , wherein the distal end of one of the cutting blades of the pair of scissors is provided with a transverse stud directed towards the distal end of the other cutting blade of the pair of scissors. 
     
     
       3. Instrumentation kit according to  claim 1 , wherein the cutting edges of the cutting blades of the pair of scissors are equipped with microteeth. 
     
     
       4. Instrumentation kit according to  claim 1 , wherein the cutting blades and the cutting edges of the pair of scissors have a curvature in a vertical plane, the vertical plane being perpendicular to the horizontal plane in which the pair of scissors lie. 
     
     
       5. Instrumentation kit according to  claim 1 , wherein the pair of scissors further comprises two handles, the handles being articulated via the distal ends of their respective cutting blades. 
     
     
       6. Instrumentation kit according to  claim 1 , wherein the distal ends of the cutting blades of the pair of scissors are rounded. 
     
     
       7. Instrumentation kit according to  claim 6 , wherein the distal ends of the cutting blades of the cutting tool are equipped with a flat disc along the respective cutting edge. 
     
     
       8. Instrumentation kit according to  claim 1 , wherein one of the cutting blades of the cutting tool has a concave cutting edge, while the other cutting blade of the cutting tool is provided with a convex cutting edge. 
     
     
       9. Instrumentation kit according to  claim 8 , wherein each cutting blade of the cutting tool has a rectilinear part between its axis of articulation with the other cutting blade of the cutting tool and an incurved part forming the cutting edge, and wherein an angle A of between 5 and 90 degrees is formed by the intersection of a first straight line passing through the ends of the incurved part in a second straight line passing through the rectilinear part. 
     
     
       10. Instrumentation kit according to  claims 8  to  7 , wherein at least one of the cutting edges of the cutting blades of the cutting tool is equipped with microtech.
