A bone extraction device having a protective sleeve, comprising a bone drill (1) and a shielding sleeve (2)； the bone drill (1) may simultaneously crush bone during bone extraction, thus saving time； a positioning tip (131) may effectively prevent a drill bit from deviating during bone extraction, thereby reducing damage caused to surrounding bone； a bone fragment storage portion (12) facilitates the storage of bone fragments； a spiral-shaped fragment collecting portion (22) is an elastic component and is compressible, being used in cooperation with the bone drill (1)； the fragment collecting portion (22) may have a protective effect during drilling, and thus one need not worry about drilling too deep. Compared with existing bone extraction drills for dental implant surgery, the described bone extraction device has the advantages of being simple to operate and being capable of achieving accurate positioning, while drilling depth may be controlled and loss of bone fragments may be reduced.
