Detailed description of the invention
Preferred implementation of the present utility model is described in detail below with reference to accompanying drawing, special for prominent technology of the present utility model
Levy, technical scheme and technique effect, suitably omit the detailed description to technology contents well-known to those skilled in the art.Need explanation
, in present specification, such as " vertically ", " level ", the directional terminology of "left", "right" etc. should be understood for accompanying drawing
The description of shown state, it is not intended to this utility model specific direction and the restriction of structure.
Between the condyle according to a kind of embodiment of this utility model osteotomy adjusting means include right side condyle between osteotomy bootstrap block 1,
Osteotomy bootstrap block 2, handle 3 and osteotome 4 between the condyle of left side.Wherein, Fig. 1 and Fig. 3 show respectively this adjusting means right side,
Osteotomy bootstrap block 1 and 2 between the condyle of left side.
As Figure 1-3, between the condyle of right side, between osteotomy bootstrap block 1 and left side condyle, osteotomy bootstrap block 2 is symmetrical block
Structure, has between condyle stationary plane between stationary plane 11 and condyle and constitutes " L " type angle on the block structure of osteotomy bootstrap block between the condyle of right side
The far-end stationary plane 12 postartis supporting plate 13 vertical with stationary plane between condyle and far-end stationary plane and hang down along with far-end stationary plane
Nogata, to the osteotomy locating slot 14 extended, has certain distance d between stationary plane between the bearing of trend of osteotomy locating slot 14 and condyle,
This distance d is in art needs to revise the osteotomy amount size of osteotomy between regulation condyle.There is on the bottom surface of block hole 15, handle location,
For coupling with the positioning pin column 31 on handle 3, constitute coupling arrangement.
According to a kind of embodiment of the present utility model, far-end stationary plane 12 has zigzag structure, thus can be firm
Amplexiform on the osteotomy of distal face being positioned at femur.
As symmetrical structure, between the condyle of left side, osteotomy bootstrap block 2 also includes stationary plane between condyle, far-end stationary plane, postartis torr
Plate, osteotomy locating slot, between far-end stationary plane and condyle, stationary plane constitutes " L " type angle, stationary plane and far-end between postartis supporting plate and condyle
Stationary plane is perpendicular, and osteotomy locating slot extends along the direction perpendicular with far-end stationary plane, and fixing between this bearing of trend and condyle
There is between face certain distance d.The hole, handle location having on the bottom surface of bootstrap block 2, is used for and the positioning pin column 31 on handle 3
Couple, constitute coupling arrangement.Zigzag structure can be provided with on far-end stationary plane.
As shown in Figure 6, osteotome 4 is made up of blade 42, osteotome hand holding handle 43, attacking head 44 3 part, sets on blade 42
In respect of graduation mark 41.
When position carries out osteotomy operation between to left side condyle, osteotomy bootstrap block 2 between condyle on the left of use, on the right side of processing between condyle
Time use on the right side of osteotomy bootstrap block 1 between condyle.
As shown in Figure 8, with on the right side of regulation during osteotomy operation between condyle, handle positioning vertical column 31 is inserted osteotomy between the condyle of right side
In hole 15, two handle location on bootstrap block 1, connect osteotomy bootstrap block 1 (see Fig. 5) between handle 3 and right side condyle.Doctor holds
Handle 3, is adjacent to stationary plane between condyle 11 face between the right side condyle of femur 100, and is pasted by the far-end stationary plane 12 with broached-tooth design
The osteotomy of distal face of tight femur 100, is inserted into postartis supporting plate 13 in patient articular gap, holds femur 100 postartis and can consolidate
Between the condyle of fixed right side, the position of osteotomy bootstrap block 1, then extracts handle 3.Now, doctor can hold the osteotome hand holding handle on osteotome 4
43, in the osteotomy locating slot 14 blade 42 being inserted between the condyle of right side on osteotomy bootstrap block 1 (see Fig. 8).Osteotomy locating slot 14 is right
Between end face and condyle, distance between the right side of stationary plane 11 is in art needs to revise osteotomy amount d of osteotomy between regulation condyle.Doctor
Raw using bone hammer to tap the attacking head 43 on osteotome 4 in art, pounded by blade 42 in femur 100 on graduation mark 41 is corresponding
At scale, i.e. reach the required osteotomy degree of depth.Osteotomy bootstrap block 1 between the condyle of the most desirable lower right side, the most i.e. completes between the condyle of right side
Regulation osteotomy operation.On the left of regulation between condyle during section, use osteotomy bootstrap block 2 between the condyle of left side instead and repeat aforesaid operations.
This utility model is described by description above content by way of example, and these describe and are intended to help ability
Territory those of ordinary skill understands principle of the present utility model and certain exemplary specific implementation.Ordinary skill people
Member knows, according to these principles, this specific implementation can be made change or replace, but this change or replacement are all
It is contemplated as falling within protection domain of the present utility model.
