摘要:
The present invention is a positioning and bone meal collecting device for a dental handpiece which comprising a cylinder-shape bone meal collector, a flexible component, a drill bit positioning cylinder, and a positioning screw. The bone meal collector is a cylinder-shape sleeve, and one end thereof is preferably with smooth end face with a through hole provided in the center thereof. The flexible component provided in the bone meal collector is preferably a spring. One end of the flexible component is connect to the inner side of the end with smooth end face, and the other end thereof id provided with a coil for securing to the flange of said drill bit positioning cylinder by elastic force, thereby it can removably connect to the flange of said drill bit positioning cylinder. The positioning screw is further provided on the drill bit positioning cylinder and it can set the desired drilling depth by adjusting the position of the positioning cylinder so as to preset the drilling depth.本發明係為一種可以用於一牙科手機之定位集骨裝置,其係由套筒狀之骨粉收集管、彈性構件、鑽頭定位套環與定位螺絲等零件所組裝而成。該骨粉收集器係為一圓形套管,其之一端係較佳地為具有光滑圓弧之端面,且在該光滑圓弧端面中心係設有一孔洞,該圓形套管之內部設置有一較佳地為一彈簧之彈性構件,該彈簧之一端係與該圓形套管之光滑圓弧端面之內側結合,且該彈簧之另一端則具有可藉由彈力來箍合該鑽頭定位套環的凸緣之端面線圈,而使其可移除地連接至該鑽頭定位套環的凸緣上;該鑽頭定位套環上進一步設有一定位螺絲,該定位螺絲可以藉由調整該套環的位置,來設定鑽孔深度以達到預設鑽孔深度之效果。41‧‧‧鑽頭43‧‧‧鑽柄45‧‧‧定位套環47‧‧‧定位螺絲51‧‧‧骨粉收集器53‧‧‧孔洞57‧‧‧彈性構件59‧‧‧凸緣
