With specific orientation, with specific azimuth configuration and operation, therefore be not considered as limiting the invention.
The isometric measuring device of ligament reconstructive provided by the invention, includes upper shield 1, feeler lever 2 and nailing mechanism, nailing mechanism
Nail 4 and bucking bar 5 are visited comprising positioning, the tail portion that nail 4 is visited in the positioning is provided with holes 41, and bucking bar 5 is detachably connected on institute
In stating with holes 41, positioning can be stamped on femur 91 by nailing mechanism and visit nail 4, after removing bucking bar 5, feeler lever 2 can hook
Enter in described with holes 41.Axially extending bore is provided in the upper shield 1, feeler lever 2 is threaded through in the axially extending bore of upper shield 1, upper shield 1
Comprising tunnel adaptation portion 12 and limiting end cap 11, tunnel adaptation portion 12 is integrally formed or is fastenedly connected with limiting end cap 11, described
Feeler lever 2 sequentially forms depth sounding portion 21 and contact site 22 along proximal end to distal direction, depth sounding portion 21 be integrally formed with contact site 22 or
It is detachably connected, 22 axially extending direction of contact site exists with respect to 21 axially extending direction of depth sounding portion to be bent.
In embodiment, as shown in Figure 1 and Figure 2, the bucking bar 5 includes the sub bar 51 being detachably connected and female bar 52.Such as figure
Shown in 3, the tail portion that nail 4 is visited in the positioning is provided with holes 41, and clamp groove 511, folder are respectively arranged on sub bar 51, female bar 52
Convex block 521 is held, clamp groove 511 matches with clamping convex block 521, and clamping convex block 521 reaches clamping after can running through with holes 41
In groove 511.In actual use, doctor goes out isometric position by theoretical calculation, is directed through by nailing mechanism
Skin stamps one or more positioning in theoretical 91 isometric positions of femur and neighbouring position and visits nail 4.Squeezing into for nail 4 is visited in positioning
Operating process is：Sub bar 51, female bar 52 and positioning first are visited nail 4 to assemble, pass is extend by existing incision on dermatology
Chamber is saved, after positioning spy nail 4 is fixed on femur 91 using the mode of such as impact, will be torn open between sub bar 51 and female bar 52
Separation is unloaded, is taken out from above-mentioned incision on dermatology.Preferably, it is set on the proximal end of sub bar 51 and/or the proximal end of female bar 52
There is button 512, facilitate the push-in and draw out operation of sub bar 51 and/or female bar 52.Preferably, 5 diameter of bucking bar is less than positioning and visits
Follow closely 4 diameters, that is to say, that after the completion of mutually being assembled between sub bar 51 and female bar 52, cross-sectional profiles should be located at positioning and visit nail 4
Inside cross-sectional profiles, the push-in and draw out operation of sub bar 51 could be facilitated in this way.Preferably, the diameter of nail 4 is visited in the positioning
The a diameter of 1.5mm of bucking bar 5 formed for 2mm, sub bar 51 with female bar 52.
In embodiment, the rigid bar as shown in figure 4, feeler lever 2 is integrally formed, depth sounding portion 21 linearly prolongs
It stretches, 22 shape of contact site is U-shaped, L-shaped or other shapes with bending.During actual operation, the tunnel adaptation portion of upper shield 1
12 are first mounted in one of duct in the multiple ducts being drilled on shin bone 92, these ducts are used only as the survey of isometric point
Amount is significantly larger than the duct eventually for the diameter of the osseous tunnel of artificial ligament installation.It limits 11 diameter of end cap and is more than duct
Diameter, prevent entire upper shield 1 from entering in duct, due to duct with respect to 92 axial direction of shin bone there are angle,
It is a smooth surface to limit 11 axial distal end face of end cap, and for adapting to the shape of 92 outer surface of shin bone, this allows for limiting end cap
11 have variation on thickness.Depth sounding portion 21 is additionally provided with handle 23 on proximal end, and preferably of course, the depth sounding portion 21 also may be used
To be that proximal diameter is big, the structure under distal diameter facilitates doctor's hand-held.When in use, depth sounding portion 21 will across duct
Contact site 22 send to the positioning on femur 91 and visits 4 hooks of nail, and contact site 22 is visited with one of positioning after nail 4 hooks together,
Patient knees are bent and stretched, the displacement of 2 proximal end of observation feeler lever then moves on contact site 22 and is hooked together to another positioning spy nail 4,
Knee operation is bent and stretched in repetition, until during 2 proximal displacement unobvious of feeler lever, obtains the isometric point on femur 91.Preferably, it also sets up
There is a sheath 3, sheath 3 is in axial direction provided with through-hole, upper shield 1, sheath 3, feeler lever 2 nested encryptions successively, it is further preferred that
As shown in figure 5, the sheath 3 includes observation portion 31, the observation portion 31 is located at the proximal end of sheath 3, and observation portion 31 is by transparent modeling
Material is made, and in this way in isometric measurement process, can observe the movement of feeler lever 2 in time by observation portion 31.Preferably, it is described
A diameter of 1.5mm of sheath 3.Preferably, the depth sounding portion 21 of the feeler lever 2 and contact site 22 are detachably connected, during use
It is assembled under arthroscope；Preferably, the contact site 22 can also be the thin seal wire or steel wire that can carry out bending, feeler lever
2 initial shapes are linear, and after contact site 22 is extend into articular cavity, under the cooperation of arthroscope, contact site 22 is carried out
Bending, which facilitates the insertion of feeler lever 2, but additionally increases the bending operation process of contact site 22.
In preference, above-mentioned nailing mechanism can also be omitted, is directly penetrated from the duct accomplished fluently using feeler lever 2,
After contacting with the surface of femur 91, carry out bending and stretching knee motions to determine isometric point, contact site 22 does camber, on the one hand prevents
91 surface of femur is caused to wear during a measurement is changed, certain contact dynamics is on the other hand can also ensure that, prevents
It slides, the structure measurement process is simpler, but nailing mechanism is combined in opposite embodiment and squeezes into the structure that nail 4 is visited in positioning,
Prevent the effect that feeler lever 2 slides poor in measurement process, measurement accuracy also Shortcomings.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring the substantive content of the present invention.In the absence of conflict, the feature in embodiments herein and embodiment can arbitrary phase
Mutually combination.
