Definitions

  • the invention refers to an instrument used in plastic surgery, particularly in rhinoplasty, which accomplishes the most accurate osteotomy of the nasal hump. (Drawing Nr. 5).
  • the conventional instruments for. the removal of the hump of the nose are mainly chisels, special hand - or motorsaws or rongeurs, At present, with the instruments in use, the inaccurate and wrong osteotomies of the nasal hump are very frequent and the results are various complications and danger for the patients.
  • This inadequacy of the known instruments for the osteotomy of the nasal hump to facilitate the surgeon to accomplish accurate and not dangerous osteotomies was the motive which pushed me to the invention of DNCS.
  • NASION is the furthest and deepest point of the dorsum of the nose. (Drawing Nr. 6 : N).
  • NASION is the most important, permanent landmark for the osteotomy of the nasal hump.
  • the surgeon defines the osteotomy plane of the nasal hump and subsequently directs the chisel or any other of the known instruments approximately, according to his subjective criteria only, and on the base of some abstract uncertain momentary estimation.
  • the surgeon has the possibility to attend the approaching of the stops of the chisel to the mouth of the driver, controlling exactly the advancement of the edge of the chisel into the base of the hump.
  • the long beveling of the cutting part of the chisel precludes undesirable fractures of the nasal bones.
  • SAFETY The chisel of DNCS is moving in the driver and only as far as the Nasion, which is the obligatory destination of it. So, every complication and dangerous condition, such as injury of the soft tissue, damage of the nasal bones, additive hemorrhage from the injured front ethmoidal artery, opening of the frontal sinus, injury of the meninges or injury of the olfactory nerves are prevented.
  • DNCS HANDINESS. DNCS is used very easily by right - , or left - handed surgeons.
  • DNCS The handling of DNCS is done only by the one hand of the surgeon so that his other hand is free for managing the hammer.
  • Object of this invention is a surgical instrument, used in plastic surgery and particularly in aesthetic surgery of the nose, which instrument ensures the accurate osteotomy (cut off) - of the nasal hump.

  • the DRIVER I
  • the CHISEL (2) It is the cutting component of DNCS.
  • the HANDLE (3) It is the component for operating the driver (l).
  • the driver (I) is held and stabilized on the osteotomy plane.

  • Drawing 5 illustrates the DNCS positioned on the nose, ready for the osteotomy of the hump.
  • Drawing 6 illustrates wrong osteotomies (A,B) because of inaccurate estimation of the real position of Nasion (N) and the osteotomy line of the hump via the DNCS.
  • DNCS is composed of the driver (I), the chisel (2) and the handle (3).
  • the mouth (I.I) is the open side of the driver (I) into which the chisel (2) is inserted.
  • the bar (I.2) of the driver (I), is arched on the underside.
  • the centre of the arch is called Antinasion (I.7).
  • the chisel (2) is characterized from a distal narrow part (2.4) and a proximal wide part (2.I).
  • the proximal wide part (2.I) of the chisel (2) is characterised from the stops (2.2) and the pole (2.5).

  • the drivers - socket (I.3) is characterised from its si ⁇ es (I.8) (I.9).
  • the localization of the Nasion is made by two ways a.
  • the Nasion is marked on the skin and a straight needle is verticaly inserted, fixed on the bone. Afterwards, the driver is inserted under the soft tissus of the nasal dorsum so that the arch of the bar (I.2) slips softly on the hump as far as it meets the tip of the needle on the Nasion (Drawing 6:N).
  • the driver (I) is inserted under the soft tissue of the nasal dorsum, slipping on the hump. As far as the arch of the bar (I.2) reaches the root of the nose, delicate back and forth movements are made to lacalize the deepest point of the root which is the Nasion (Drawing 6:N).
  • the driver (I) After the localization on Nasion (N), which is the most important landmark for the osteotomy of the hump, the driver (I) is held via the handle (3) firmly, so that the arch of the bar (I.2), particularly the Antinasion (I.7) and Nasion (N) coincide.
  • the chisel (2) is inserted into the mouth (I.I) of the driver (I) and is advanced as far as the cutting edge (2.3) of it comes in contact with the starting point of the osteotomy.
  • the chisel (2) is held from the driver (I) itself, so that the other hand of the surgeon is free. With this free hand the surgeon holds the hammer and administers gentle blows against the pole (2.5) of the chisel (2) accomplishing the osteotomy.
  • the surgeon controls the course of tne osteotomy attending the approaching of the stops (2.2) of the chisel (2) to the rims of the mouth (I.I) of the driver (I). So, as soon as the stops (2.2) of the chisel (2) touch the rims of the mouth (I.I) tne osteotomy is finished, because the cutting edge (2.3) of the bevel (2.6) of the chisel (2) simultaneously has arrived to the bar (I.2) of the driver (I), particularly to the Antinasion (I.7) which, as mentioned, coincides with the Nasion (N).
  • the chisel (2) with the driver (I) have the similar functional relation of the drawer with its drawer - sheath.

Abstract

L'invention se rapporte à un instrument de chirurgie qui sert à pratiquer l'ostéotomie précise de la bosse nasale (système de bistouri à destination nasion, dit DNCS). Ce système DNCS est constitué par un instrument en métal inoxydable composé d'un guide-lame (1), d'une lame (2) et d'un manche (3). Ces trois éléments sont montés lors de l'utilisation et démontés pour permettre leur nettoyage et leur stérilisation. Le guide-lame (1) permet, en dépit du manque de visibilité du champ opératoire, au chirurgien de localiser plus facilement avec précision le nasion (N), qui constitue le point de destination de l'ostéotomie. Le guide-lame (1) comporte une ouverture (1.1) permettant l'introduction de la lame (2). L'antinasion (1.7) de sa barre (1.2) vient se placer sur le nasion (N). La lame se déplace sur l'appui glissant (1.6) du guide-lame et entre les ailes (1.4) et également entre les cadres de glissement (1.5). Le guide-lame comprend également une douille (1.3) permettant son assemblage avec le manche (3). La lame (2), qui est l'élément coupant du système (DNCS) comporte une partie distale étroite (2.4) avec un biseau (2.6) et un bord tranchant (2.3). Cette partie de la lame s'adapte dans le guide-lame (1). La lame (2) comprend une partie proximale large (2.1) avec deux butées (2.2) et un pôle (2.5). Le manche (3) est assemblé par sa languette (3.1) au guide-lame (1). En outre, la position du manche (3) dans cet espace sert de guide pour pratiquer une ostéotomie à hauteur constante des os du nez. Ainsi, un tel système DNCS sert d'instrument grâce auquel le chirurgien-plasticien élimine le problème du manque de visibilité du champ opératoire pendant la rhinoplastie, en particulier pendant l'ostéotomie de la bosse nasale, et peut effectuer une telle opération, à l'aide de ce système DNCS, avec une haute précision et sans danger.
