Preferably, the diameter in the middle part of described collection portion is more than the diameter at two ends.
Preferably, the edge of a knife of described spiraled knife is generally aligned in the same plane with the front end face of cutting part, and blade is twist
Arrange to cutting part rear end.
Further, the edge of a knife of described spiraled knife is through the center of circle of cutting part front end face.
Further, described spiraled knife at least two, the edge of a knife of spiraled knife is uniformly distributed.
Using method of the present utility model: open one osculum on patient skin, with dilator, osculum is strutted, then will cut
The front end cutting portion is inserted into ilium surface, connecting portion b connects motor or artificial handle, rotates whole micro-wound bone taking device,
The direction identical with the hand of spiral of spiraled knife (the broken ilium that the edge of a knife i.e. can be made to cut is transported to collection portion) rotated,
Take off micro-wound bone taking device after reaching desired depth and i.e. can get broken ilium.
The beneficial effects of the utility model: otch little (within caning be controlled in 1 centimetre), go out insufficiency of blood, and wound is little；The completeest
Becoming punching to take bone, operating time is short.
