Description

一种通过高频振动扩孔的个性化骨钻 技术领域
本发明涉及植牙技术领域。
背景技术
目前在牙种植手术中，大都采用螺纹连接的方式将牙种植体安装在口腔内，其需要先在患者的牙槽骨钻取较大的孔洞。该手术会对牙槽骨及黏骨膜瓣造成巨大且没必要的损伤和骨量缺损，从而延长了患者的康复周期。种植手术中在给患者钻孔时均采用标准规格的钻头，钻取标准圆柱状的孔洞，不能根据患者特殊的口腔情况钻取特殊结构的孔洞。
发明内容
针对以上缺点，本发明提供本发明设了一种通过高频振动进行镗孔的骨钻，其通过3D打印个性化钻头，进而制备不同形状、不同深度的种植孔。
一种通过高频振动扩孔的个性化骨钻，包括钻体、振动轴、钻盖和个性化钻头，所述钻体为圆柱体，所述钻体的轴线处设有振动轴定位孔，所述钻体底部设有摆件活动腔，所述钻体外壁对应摆件活动腔侧壁处设有外螺纹，所述振动轴由轴体与偏心摆件组成，所述轴体与振动轴定位孔相适配且长度大于振动轴定位孔的深度，所述轴体的上端设有与外设的动力源联动的连接口，所述偏心摆件位于摆件活动腔内且与所述轴体的底部固定连接，所述偏心摆件的重心远离轴体，所述钻盖呈上大下小的圆锥体状，钻盖上部设有内螺纹，该内螺纹与钻体的外螺纹相适配，所述钻盖底端设有安装个性化钻头的突出平台。
进一步，所述钻体还包括两个轴向设置的冷却液输送通孔，所述冷却液输送通孔与振动轴定位孔平行，且均与摆件活动腔连通。
进一步，所述突出平台由易导热材料制成，所述突出平台内设有温度传感器探头。
本发明公开的牙种植装置通过振动进行镗孔，尽可能地保留了患者牙槽骨骨量，减少了患者的损伤，缩短了患者的康复周期。可以通过3D打印的个性化钻头制备不同形状、不同深度的种植孔。通过偏心摆件旋转促使整个骨钻振动，结构简易、稳定、可靠。轴体与偏心摆件的一体式设计结构紧凑，不易产生过大的晃动与碰撞，且便于组装操作。
