摘要:
Tool for drilling bone tissue, which has the advantage of having a cutting tip with a flat effective shape that prevents perforation of the Schneider membrane or injury to the dental nerve when drilling close to them. The tool is disposed along an longitudinal axis (7) and comprises a non-cutting main body (1), a narrowed area (2) for retaining bone and a cutting tip (3), which comprises cutting blades (4), each one of which is provided with a straight front cutting edge (5) substantially perpendicular to the longitudinal axis (7) and a substantially straight lateral cutting edge (6) that forms an angle of between 0° and 10° with the longitudinal axis (7). Bone-particle-retaining spaces (9) for receiving bone are disposed between the cutting blades (4) and are connected to the narrowed area (2).用於鑽骨頭組織之工具,其具有包含一大致平坦有效形狀之切削尖端的優點,用於防止當鑽到靠近史奈德膜時穿破該史奈德膜而傷害牙神經。此工具沿一縱軸(7)設置且包括一非切削主體(1)、一用於保持骨頭的被窄化區域(2)、及一切削尖端(3),此切削尖端(3)包括切削刀(4),每一個切削刀(4)設有大致垂直於縱軸(7)的直前切削刃(5)及大致平行於縱軸(7)的直側切削刃(6),此直側切削刃(6)與縱軸(7)形成一介於0°與10°之間的角度。用於容納骨頭的骨頭微粒保持空間(9)被設置在切削刀(4)之間且被連接到被窄化區域(2)。
