Portion 401 enables to mill osteotome body 30 to generate bending, so that mill osteotome head 20 can be bent in one direction.
Specific operation process: due to first connecting portion 401 close to one end of second connecting portion offer for push rod 402
The first groove body 405 for matching of top, when pushing push rod 402, first connecting portion 401 can be along articulation piece 403 to side
Direction rotation is used for when first connecting portion 401 is rotated since second connecting portion is offered far from the side on 402 top of push rod
The second groove body 404 matched when bending with first connecting portion 401, first connecting portion 401 are in contact not with second connecting portion
Meeting can cooperate in the second groove body 404 until completely attaching to.
In addition, the one end of first connecting portion 401 far from second connecting portion is fixedly connected with mill osteotome head 20.
Any value that first connecting portion 401 is 0 ° to 60 ° relative to the range of the bending angle of second connecting portion.
The top of push rod 402 is set as a tip, is set as one after by top with acclive push rod 402, by
Value is determined in the internal diameter of the first groove body 405 for one, when the diameter of push rod 402 is greater than the internal diameter of the first groove body 405, push rod 402
The rotation of first connecting portion 401 can not be continued to press on, reaching rotation maximum value at this time is 60 °.
Due to the setting of the second groove body 404, the diameter by the second groove body 404 is calculated is matched with first connecting portion 401
Maximum angle when conjunction is also 60 °, at this time since the first groove body 405 and the second groove body 404 have been maximum cooperations, so first
Interconnecting piece 401 is up to 60 ° relative to the bending angle of second connecting portion.
Minimally invasive mill bone tool provided in this embodiment, since bending apparatus 40 is arranged, and bending apparatus 40 can to grind
Osteotome head 20 is when carrying out mill bone operation, due to the selection of specific position, can make in the case where drilling small, selection is closed
The position of reason is gone to carry out mill bone operation, so that the linear motion of mill osteotome head 20 preferably reaches the position of pedicle of vertebral arch bone, so that
It performs the operation more convenient.
As shown in figure 3, on the basis of the above embodiments, further, minimally invasive mill bone tool provided in this embodiment is also
Including shell；The card slot that transmission mechanism is set for card is provided in shell；It grinds osteotome head 20 and stretches out shell；Shell is far from mill osteotome
First 20 one end, which is provided with, is connected by power handle 90；Shell includes mutually matched first shell 10 and second shell 70；And first
The length of shell 10 is greater than the length of second shell 70.
Wherein, the shape of shell can be a variety of, such as: centrum, cuboid or cylindrical body etc., preferably, shell
