Specific embodiment
The present invention will be further illustrated below in conjunction with specific embodiments.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please limited range.
Described in the utility model is a kind of splashproof bone grafting instrument of orthopaedics, and main structure includes outer tube 1, and the outer tube 1 is modeling
Expect material, the outside of the outer tube 1 is rotatably connected to axle sleeve 2, and bearing is equipped between the outer tube 1 and axle sleeve 2, enables axle sleeve 2
It is rotated around outer tube 1, is provided with first through hole 3 on the axle sleeve 2, the second through-hole 4 is provided on the outer tube 1, passes through rotary axle box 2
First through hole 3 can be made to be overlapped with the second through-hole 4, rotary axle box 2 makes first through hole 3 and the second through-hole 4 when needing to import broken bone
It is overlapped, broken bone is injected out of coincidence hole, activity is plugged with connecting tube 5, the caliber of the connecting tube 5 in the first through hole 3
Size is matched with first through hole 3, the second through-hole 4, and one end of the connecting tube 5 is communicated with funnel 6, is injected using funnel 6 broken
Bone is more convenient and safe, more efficient, and connecting tube 5 is inserted into the hole of coincidence when importing broken bone, and broken bone is injected from funnel
, the inner wall of the outer tube 1 is equipped with sliding rail 7, slidably connects delivery pipe 8, the height of the delivery pipe 8 on the sliding rail 7
Degree is less than outer tube 1, and the delivery pipe 8 can slide up and down in outer tube 1, and the outer tube 1, the equal both ends open of delivery pipe 8 are convenient for
