Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and particularly relates to an oral sinus floor mucosa dissector. Background Art

[0002] Due to the special anatomical structure of the posterior maxillary region, long-term tooth loss and age-related changes in people often lead to maxillary sinus pneumatization and alveolar bone resorption. Usually, on imaging, it is manifested as insufficient residual bone height (RBH) of the maxillary sinus, which brings certain difficulties to implanting posterior maxillary teeth. The maxillary sinus floor elevation through the alveolar ridge crest is an effective surgical option, which can restore sufficient alveolar bone height at the atrophied site in the posterior maxillary region. The maxillary sinus floor elevation through the alveolar ridge crest includes two steps. First, break through the maxillary sinus floor with an implant cavity preparation instrument. Then, use special instruments to strip the sinus membrane, submucosa and periosteum from the maxillary sinus floor and displace them toward the root, implant biomaterials to maintain the space, without penetrating the sinus membrane soft tissue. Finally, implant one or more implants.

[0003] The forces generated during the operation can be divided into the separating force for stripping the maxillary sinus mucosa and the lifting force for elevating the maxillary sinus mucosa. Whether there is a perforation depends on whether the two forces are within the tensile strength range that the maxillary sinus mucosa can withstand, and whether the initial stripping of the maxillary sinus mucosa is sufficient plays a crucial role. Currently, the maxillary sinus dissection tools on the market can only unilaterally dissect 0.9 mm during the fractional dissection of the sinus floor mucosa. The dissection range is limited, requiring the doctor to operate gently during the operation to avoid applying excessive force to the mucosa and causing perforation, which will prolong the operation time, reduce the operation efficiency, and cause discomfort to the patient during the operation. The diameter of the disc-shaped dissector stripped by the traditional maxillary sinus dissection tool is only 3.5 mm. Content of the Utility Model
