Specific embodiment
To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model
Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work
Obtained all other embodiment is put, the range that the utility model is protected is belonged to.
As shown in Figure 1, the utility model provides length measurement and positioning device in a kind of Replacement of Hip Joint, including
One steinman pin 1 and chain scale 2, the first steinman pin 1 have tip 11 and tail cap 12, and the first end of chain scale 2 is sheathed on the
On one steinman pin 1, the tip 11 of first this low needle is capable of fixing on ilium, is measured on ilium by the way that chain scale 2 is straightened
Fixed point and the distance between greater trochanter.
First steinman pin 1 is fixed on ilium, and passes through setting by length measurement and positioning device in Replacement of Hip Joint
The distance between fixed point and greater trochanter before and after displacement technique on ilium are measured in the chain scale 2 on the first steinman pin 1, from
And the length of double lower limb is precisely controlled, the prior art is avoided by touching the patient's body surface bone mark point come under comparison pair
Limb length, to the biggish defect of the error in judgement of double lower limb length in art.
The side of optionally embodiment, the close tail cap 12 of the waist of the first steinman pin 1 is provided with limited cap 13,
Chain scale 2 can slide between tail cap 12 and limited cap 13.
Optionally embodiment, locator further include the second steinman pin 3, and the second end of chain scale 2 is sheathed on
On two steinman pins 3, the second steinman pin 3 be capable of fixing on ischium be used as drag hook use.
Second steinman pin 3 is fixed on ischium as muscular retractor, can stop soft tissue, and help appears notch, not shadow
Ring the visual field in art.
Optionally embodiment, the structure snd size phase of the structure snd size of the second steinman pin 3 and the first steinman pin 1
Together, the second end of chain scale 2 can be slided between the tail cap 12 and limited cap 13 of the second steinman pin 3.
Limited cap 13 can play the role of limit to chain scale 2, prevent chain scale 2 from the first steinman pin 1 and
It is detached from two steinman pins 3.
The distance between they are inconvenient to adjust after first steinman pin 1 and the second steinman pin 3 fix, so chain scale
2 both ends can be slided between tail cap 12 and limited cap 13, prevent from not having cushion space in 2 loading process of chain scale and causing
Tissue damage.
Optionally embodiment, chain scale 2 are fastened by multiple cuff links 21 are end to end.
The length of each cuff link 21 is fixed value, be it is designed in advance, by the quantity of several cuff links 21, you can get it
The distance between fixed point and greater trochanter on ilium.
The length of optionally embodiment, each cuff link 21 is 1cm.
According to Human physiology feature, size and individual difference, the length of cuff link 21 is set as 1cm, be convenient for measuring and
It counts.
Optionally embodiment, locator have further included needle device 4, play needle device 4 and include sliding hammer 41 and slide bar 42,
One end of slide bar 42 have limiting section 43, the other end have connection pawl 44, sliding hammer 41 be slidably set to limiting section 43 with connect
Between pawl 44, connection pawl 44 can be cooperatively connected with tail cap 12.Play the structure of needle device 4 referring to fig. 2.
After acetabular bone displacement technique, steinman pin is removed from human body, as shown in figure 3, the tail cap 12 of steinman pin is consolidated
Fixed to hold sliding hammer 41 to connecting on pawl 44 and first slide to the direction close to tail cap 12, the moment of stopping is again to separate tail cap 12
Direction throws away sliding hammer 41, and when sliding hammer 41 slides into rapidly at limiting section 43, due to inertia, sliding hammer 41 is with moving slide-bar 42 to separate
The direction of steinman pin is mobile, so that steinman pin be got off from human body.
