Description

Technical Field

[0001] The utility model relates to the technical field of maxillary sinus endothelium, in particular to an auxiliary device for lifting the maxillary sinus endothelium. Background Art

[0002] The shape of the maxillary sinus is basically consistent with the maxillary body, and can be divided into a base, a tip, and four walls: front, back, upper, and lower. The maxillary sinus lining is a thin membrane inside the maxillary sinus. Maxillary sinus lining filling usually refers to filling some substances under the maxillary sinus lining to raise the sinus lining and improve sinus ventilation and drainage. This treatment method is usually used for sinus diseases such as chronic sinusitis and nasal polyps. The filling material can be autologous tissue (such as autologous bone meal, autologous fat, etc.) or synthetic material (such as biodegradable materials such as polylactic acid and polycaprolactone).

[0003] For example, the prior art publication number CN216777277U is an auxiliary device for raising the frontal sinus endothelium. The utility model squeezes the airbag, which delivers gas into the trachea. The gas then enters the air inlet cavity on the connecting rod, the grip rod and the umbrella-shaped glass through the trachea, and is discharged through the air outlet on the umbrella-shaped glass to inflate the rubber isolation sleeve, thereby increasing the volume of the rubber isolation sleeve, and the sinus membrane also becomes larger and raised, which can effectively prevent the sinus membrane from rupturing.

[0004] However, the above-mentioned prior art still has the following problems when used: after the maxillary sinus lining is lifted, bone powder needs to be filled inside the maxillary sinus, and when filling the bone powder, the above-mentioned device needs to be taken out, and then the bone powder is filled into the maxillary sinus. After the above-mentioned device is taken out, the maxillary sinus lining will automatically fall down, thus affecting the filling of the bone powder. Based on this, the utility model provides an auxiliary device for lifting the maxillary sinus lining which is convenient for filling with bone powder. Utility Model Content
