An ultrasonic tip (100) for sinus membrane elevation has a body (101), extending between a proximal part (102) adapted for mechanic coupling to a surgical handpiece generating ultrasound vibrations and a distal part (103) intended to reproduce the ultrasound vibrations transmitted by the handpiece. The distal part (103) of the tip comprises a ring-shaped part (106) of increasing cross-section with an end formed by a flat area (107) more or less perpendicular to the axis (106a) of the aforesaid ring-shaped part. The tip (100) further includes an internal irrigation channel (105) emerging on said flat area (107).本發明提供一種用於竇膜提高的超音波尖頭(100),其具有一本體(101),該本體延伸於一適以機械耦合至一產生超音波振動之外科手持件的近端部分(102)與一欲再生藉由該手持件所傳送之超音波振動的遠端部分(103)之間。該尖頭之遠端部分(103)包含一具有漸增橫截面之環形部分(106),其具有由大約垂直於該前述環形部分之軸(106a)的一平坦區域(107)所形成的一末端。該尖頭(100)進一步包括顯露於該平坦區域(107)上的一內灌洗通道(105)。100‧‧‧超音波尖頭101‧‧‧超音波尖頭之本體101a‧‧‧縱軸101b‧‧‧縱軸102‧‧‧近端部分103‧‧‧遠端部分104‧‧‧空腔104a‧‧‧螺紋105‧‧‧內灌洗通道106‧‧‧環形部分107‧‧‧平坦區域107a‧‧‧圓形邊緣108‧‧‧彎曲部σ‧‧‧彎曲角
