The utility model belongs to the technical field of oral medical appliances, and particularly relates to an sinus floor mucosa stripping appliance for assisting in a maxillary sinus lifting operation.

Background

The maxillary sinus lifting operation, also called as the alveolar ridge top approach type maxillary sinus bottom mucous membrane lifting operation, is one of the bone increment operations commonly adopted before oral implant operations when the bone quantity of the maxillary posterior dental area is insufficient in clinic. In 1994, summers designed a set of bone extrusion osteotomes, and proposed an osteotome punch-top type maxillary sinus internal lifting operation, namely, the osteotome punches the top sinus floor to fracture a local bone plate so as to lift the mucosa at the bottom of the connected sinus, so that a classical method which is widely used up to now is still provided. However, limited by the size of the bone chisel tip diameter, its range of lift is limited. Later, the scholars invented the lift-up operation in the maxillary sinus of hydraulic lift-up, has expanded the scope of peeling off to a certain extent, but because the gravity effect of liquid and the adhesive force of sinus floor mucous membrane and bone face are different, lead to the liquid that is exerted pressure to flow to the place that mucous membrane is peeled off easily to make the mucous membrane that is peeled off deviate from the target position. In order to solve the defects of the two main methods, we propose an auxiliary maxillary sinus floor mucosa stripping instrument for an internal lifting operation.
