The accurate success to operation of tibia osteotomy has a direct impact in the TKA operation, needs to determine osteotomy line position accurately.Most hospitals do not possess the airmanship application conditions, so prior art determines it is the experience that relies on the doctor mostly for the osteotomy line position, by the range estimation sensation guider being installed operates, the defective of its existence is accurately to determine best osteotomy site, thereby has influenced the effect of operation.
Summary of the invention
The purpose of this utility model be to avoid prior art accurately location defect a kind of tibia mechanical axis localizer is provided, position osteotomy operation by the mechanical axis theory, thereby effectively solve the defective that exists in the prior art.
For achieving the above object, the technical scheme that this utility model is taked is: described a kind of tibia mechanical axis localizer, be characterized in including T type parts, described T type parts are combined by first cross bar and vertical pole, also are provided with the assist location member of installing with its combination on the T type parts.
Described assist location member is that the 2nd T type parts or yi word pattern are regulated cross bar.
Described the 2nd T type parts are combined by second cross bar and longitudinal tubule (L tubule), and vertical pole is arranged within the longitudinal tubule (L tubule).
Described longitudinal tubule (L tubule) is provided with adjusts and fixes the retaining screw of distance between first cross bar and second cross bar.
Described first cross bar arranges with vertical pole is vertical with longitudinal tubule (L tubule), and first cross bar and second cross bar be arranged in parallel.
Described second cross bar is provided with for the scale groove of accurately measuring length.
Described vertical pole top is provided with for the graduation mark of accurately determining distance between first cross bar and second cross bar.
Vertical pole on the described T type parts is the screw structure of regulating the corresponding setting of cross bar with yi word pattern, and yi word pattern is regulated the cross bar bottom and is provided with the locking nut that cooperates with the vertical pole of screw structure.
Described T type parts, the 2nd T type parts and yi word pattern are regulated the member of cross bar for adopting metal material to be made.
The beneficial effects of the utility model are: described a kind of tibia mechanical axis localizer, it locatees reference by the T type parts that adopt combined type as best tibia mechanical axis, and that can accurately realize tibia mechanical axis position determines that it is simple in structure, accurate positioning, easy to use.
