Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-5 is please referred to, the utility model provides a kind of technical solution: a kind of bone surgery pricker, including hand rest 1 and micro-
Type motor set casing 5, hand rest 1 are externally connected to the first fixed link 2, and switch button 3, and are equipped with outside the first fixed link 2
Handle 4 is provided with outside one fixed link 2, and the first fixed link 2 is externally connected to the second fixed link 6, the nearly micro motor of handle 4
5 end of set casing is arcuate structure, and handle 4 is distributed about the first fixed link 2 center line bilateral symmetry, and such finger can be buckled in
It is safer during whole device is hand held on handle 4, the second fixed link 6, and second are installed outside micro motor set casing 5
Fixed link 6 is externally connected to needle stand connector 7, and interior needle fixing piece 10, needle stand connector are equipped with inside the second fixed link 6
It is provided with needle stand 8 outside 7, outer needle 9 is installed, and outer needle 9 is internally provided with interior needle 13, is hollow inside outer needle 9 outside needle stand 8
Structure, and its hollow structure inside diameter is equal with interior 13 outer dia of needle, interior needle 13 can be stored by outer needle 9, fixed
The flexible path of interior needle 13, interior needle fixing piece 10 are externally connected to transmission gear 11, and are provided with outside transmission gear 11 miniature
