The lack of basic surgical operations of the operator leads to the uncertainty of medical risks. The traditional filling method requires a long filling operation time, resulting in too long exposure time of the flap in the surgical area, aggravating postoperative edema and increasing the pain of the patient. The bone powder conveying step in maxillary sinus external lifting surgery is a key link, and the conveying speed and accuracy directly affect the success or failure of the entire operation. If the conveying instrument is not good, it is very likely to cause the loss or pollution of the bone powder.
