The maxillary sinus mucosa dissecting device comprises a dissecting head and a rotating component connected with the dissecting head. The invention changes the appearance of the stripping device by using a mechanical rotation mode, and particularly, the direction of the stripping head is driven to change by the rotation of the rotating part, so that a doctor can change the angle of the stripping head and effectively strip the mucosa of the maxillary sinus only by rotating the control handle connected with the gear after the stripping device enters the planting nest penetrating the crest of the alveolar ridge. Also, the stripping head and the rotating member may have the same or different lengths, preferably different lengths, so as to facilitate the user's exchange of instruments in the maxillary sinus surgery.
Description
Technical Field
The invention relates to the field of medical instruments, in particular to a stripping device for stripping mucosa of maxillary sinus and application thereof.
Background
When the patient's maxillary posterior teeth are missing, the bottom wall of his maxillary sinus is lowered to the position of the original root of the missing tooth. In this case, if an implant is implanted, it may penetrate the maxillary sinus wall, and for this reason it is often necessary to implant some substitute for synthetic bone to lift it to its original position, which ensures that the implant is in the maxillary bone, and this procedure is called maxillary sinus lift. At present, the most commonly used dental implant surgery for insufficient bone mass in the maxillary sinus region is maxillary sinus lifting, including maxillary sinus internal lifting and maxillary sinus external lifting. Among them, the maxillary sinus lifting operation is also called as maxillary sinus lifting operation of alveolar ridge penetration, and is usually performed in the first stage of implant implantation without additionally increasing the operation times. The maxillary sinus internal lifting operation has the advantages of simple and convenient operation, short operation time, light edema and the like, but has the defect that the operation can not be carried out under direct vision, and the maxillary sinus mucosa is easy to rupture if the operation is mishandled. Although the maxillary sinus external lifting operation can be operated under direct vision, the maxillary sinus external lifting operation has extremely high technical requirements, is accompanied by maxillary sinus breathing floating in the operation process, has great difficulty and requires doctors to have abundant clinical experience and hard professional technical level.
Traditional maxillary sinus lifting across the alveolar crest is usually performed by tapping or hydraulic methods. Wherein, the knocking method is to separate the mucosa of maxillary sinus from the maxillary sinus floor by using straight osteotomes or curved osteotomes with different diameters through a top-flushing technology; the hydraulic method separates the mucosa of the maxillary sinus from the maxillary sinus floor by using the pressure of water. Although both methods are currently in clinical use, there is still a risk of perforation of the mucosa of the maxillary sinus in blind cases. Especially when there is a partition or bone ridge in the maxillary sinus cavity, the probability of perforation is greatly increased.
