Referring to Fig. 1 to Fig. 4, the utility model embodiment discloses a kind of outer locator of femur marrow, is used to close in knee
Femur outward turning angle is positioned in section replacement operation, to be oriented to for the four-in-one osteotomy of subsequent procedures operation, from
And ensure being smoothed out for replacement knee in arthroplasty.
The outer locator of the femur marrow of present embodiment includes pedestal 1 and flipping block 2.1 lower part of pedestal has the positioning of protrusion
There is the jack 12 extended straight down, the outer wall Shanghai of the pedestal 1 to be equipped with the extension up and down for being connected to the jack 12 for plate 11, top
Strip peep hole 13, the side at least within of the peep hole 13 is provided with scale 14.
The flipping block 2 includes the shaft 23 of chucking lug 22, one of slide bar 21, two and a probe 24, which can
It is inserted in jack 12 and is slidably matched with the formation of jack 12.It is equipped on slide bar 21 for matching with the scale 14 on pedestal 1
The tag line 25 of conjunction after tag line 25 is aligned with scale 14, can indicate the position of the slide bar 21 on pedestal 1.Two positioning
Ear 22 is distributed in the both sides of slide bar 21 and can be overturn relative to pedestal 1 or so.The two chucking lugs 22 are generally relative to slide bar
21 center line is rendered as bilateral symmetry, be each provided on two chucking lugs 22 one perforation location hole 28, two
Angle between the line of centres and horizontal plane of location hole 28 forms an outward turning angle, which can be in 3 °, 5 ° and 7 °
One kind, but be not limited thereto.In the present embodiment, which is set as three from top to bottom on chucking lug 22
The outward turning angle of group, this three groups of location holes 28 is 3 °, and every group of location hole includes a positioning being located on the chucking lug of left side
Hole and a location hole being located on right positioner ear.This three groups of location holes are distinguished with letter abc respectively, are chosen with facilitating.
As selectable embodiment, the outward turning angle of three groups of location holes 28 can also be distinguished setting, wherein first group of location hole
Outward turning angle be set as 3 °, the outward turning angle of second group of location hole is set as 5 °, the outward turning angle setting of third group location hole
It it is 7 °, consequently facilitating doctor selects suitable angle in art.
Chucking lug 22 in the present embodiment includes a vertical interconnecting piece 26 and an outwardly extending extension 27, is erected
The upper end of direct-connected socket part 26 is fixedly connected with 21 top of slide bar, and extension 27 is then located at the lower end of vertical interconnecting piece 26.Due to this
Two chucking lugs 22 be can around slide bar 21 center line and the left and right overturning on pedestal 1, but the two chucking lugs 22
Flipped form be not intended to limit.Specifically, in the present embodiment, slide bar 21 can be extracted from the jack 12 of pedestal 1,
Flipping block 2 is overturn 180 ° around center line of slide bar 21 or so, then slide bar 21 is turned back to again in jack 12, thus just
The purpose for realizing chucking lug 22 and being overturn relative to pedestal 1 or so.The slide bar 21 can be prism or cylinder, and jack 12 with
Slide bar 21 matches.In the other embodiment of the utility model, the upper end of the vertical interconnecting piece 26 of the chucking lug 22 rotates
The top of slide bar 21 is connected, so, it is only necessary to chucking lug 22 be rotated, pulled out from jack 12 without by slide bar 21
Go out.
Shown in Fig. 1 and Fig. 4, shaft 23 is rotationally connected with the top of slide bar 21, and 24 level of probe is slidably connected to and turns
On axis 23.It is unlimited that form is rotatablely connected between shaft 23 and slide bar 21.There is horizontal circular hole, the middle part of probe 24 in shaft 23
With one section of round rod segment, which is inserted among horizontal circular hole, it is possible thereby to realize that probe 24 and the level of shaft 23 are sliding
Dynamic connection.In addition, from the figure 3, it may be seen that can also be further oppositely arranged on the outer wall of pedestal 1 there are two sliding slot 15, this two
A sliding slot is slidably matched with one of chucking lug 22 respectively, the two sliding slots 15 can limit chucking lug 22, make it
It will not be shaken during sliding up and down, improve positioning accuracy.
The two sides of the outer locator of the femur marrow of present embodiment can be respectively arranged with bearing mark, and one side utilizes wherein
Mark " L " is labeled as a left side, and another side is using mark " R " labeled as the right side.The outer locator of femur marrow when in use, first makes L mark court
Outside, and it is used for left femur.Wherein, the positioning plate on pedestal 1 is contacted with femoral-posterior condyles, and pedestal is then attached to distal femur
Osteotomy surface, the slide bar 21 of flipping block 2 is inserted into the jack 12 of pedestal 1, slide bar 21 is then moved, make 24 front end of probe with
Dissection point contact on femur front end face can read the position of slide bar 21 according to the scale on slide bar 21 and pedestal 1 at this time
Value, and in this, as the selection ground of subsequent procedures implantation instrument.It can be in left side stock by the location hole 28 on chucking lug 22
Positional punch on bone, to position outward turning angle.After left femur punching, the chucking lug on flipping block is overturn into 180 degree, you can in
Right side femur repeats above-mentioned action.
It is particularly shown and described the illustrative embodiments of the utility model above.It should be understood that the utility model
It is not limited to disclosed embodiment, on the contrary, the utility model intention covers included in spirit and scope of the appended claims
Interior various modifications and equivalent arrangements.
