Definitions

  • the present invention relates to the field of implantology in stomatology, and in particular to the design of a surgical instrument for oral implant surgery.
  • the maxillary sinus lift surgery system is developed with the development of oral implant technology and is the most important surgical instrument in the field of maxillary sinus implant surgery.
  • Switzerland Noble Biocare has designed a straight maxillary sinus lift surgery system. Dentsply of the United States subsequently improved the design of the elbow maxillary sinus lift surgery system to better adapt to the position of the posterior maxillary sinus.
  • Keler has designed a system with a stop to prevent maxillary sinus penetrating from accidents. This system greatly improves the safety of maxillary sinus surgery, but it does not completely avoid the occurrence of maxillary sinus membrane breakage, and it is impossible to accurately orient patients with small opening. Therefore, there is still a need to improve the safety performance and indications of surgical systems.
  • the technical scheme employed by the present invention is as follows.
  • a maxillary sinus lifting operation system comprising a lifting rod with a curved portion of the body, wherein a spacing ring step is arranged below the head of the lifting rod, and an elastic holding stop ring is arranged on the annular step .
  • the interval of the spacing is 2 mm
  • the elastic holding stop ring has an internal thread structure, and the elastic phase-to-phase structure is adjusted by the tolerance between the threads.
  • the head of the lifting rod is in the shape of an arc-shaped bullet.
  • the bending span of the body of the lifting rod is not less than 17 mm.
  • the bottom of the lifting rod is provided with a plastic base, and the base and the lifting rod are mechanically combined with an inverted concave shape.
  • the lifting rod has a diameter ranging from 2.0 mm to 5.5 mm.
  • the invention provides a maxillary sinus lifting surgery system, which comprises a lifting rod with a large span curved portion in the body, a spaced annular step platform under the head of the lifting rod, and an elastic hug on the annular step platform. Stop the ring.
  • This system can make the maxillary sinus lift surgery safer and can easily reach the position of the maxillary second molar. It can also be used for patients with small opening. This system expands the range of clinical indications for implant application.
  • FIG. 1 is a schematic view of a maxillary sinus lift surgery system in accordance with an embodiment of the present invention
  • FIG. 2 is a schematic view of a head portion of a maxillary sinus lift surgery system in accordance with an embodiment of the present invention
  • FIG. 3 is a cross-sectional view of a head portion of a maxillary sinus lift surgery system in accordance with an embodiment of the present invention.
  • a maxillary sinus lifting surgery system in the embodiment of the present invention is composed of a lifting rod 1 and a stopping ring 2 .

Abstract

La présente invention concerne un système d'opération de chirurgie implantaire consistant en une élévation du sinus maxillaire dans la cavité buccale qui a une fonction arrêt dans un micro-épaulement. Un épaulement annulaire (14) se trouve sur le dessus d'une tige d'élévation (1) et une bague d'arrêt (2) est montée sur l'épaulement annulaire. Des filetages bloquants internes sont prévus dans la surface intérieure de la bague d'arrêt et le degré de serrage est ajusté par la tolérance des filetages. Dans chaque intervalle d'arrêt de l'épaulement annulaire, un ajustement précis et une régulation précise sont permis par le degré de serrage des filetages. La précision est généralement maintenue dans la plage de 45 à 60 degrés, précisément la plage d'ajustement de la hauteur est inférieure à 0,2 mm.
