Abstract
The invention discloses a full-tunnel analog scale for cruciate ligaments reconstruction. One end of a memory alloy wire is movably connected with a miniature steel plate, the other end of the memory alloy wire is fixedly connected with a tension holder, scales are arranged on the memory steel wire, and traction lines are arranged at two ends of the miniature steel plate. The full-tunnel analog scale for cruciate ligaments reconstruction can perform accurate measurement under full-tunnel tension of a bone tunnel under the circumference that tension is maintained, meanwhile, can measure the length of ligaments in the thighbone, the tibia tunnel and the knee cavity, enables operations to be accurate, shortens operation time, can achieve the aim of acting according to actual circumferences and saves raw materials.
Description
Technical field
The present invention relates to medical instruments field, relate in particular to the full tunnel survey utensil that a kind of ligamentaum cruciatum is rebuild.
Background technology
Ligamentaum cruciatum is to keep the stable important structure of knee joint, occurs instability of knee after the damage, accelerates articular cartilage and meniscal regression, increases the occurrence probability of other structural damages of joint.Along with the development of arthroscopic techniques, adopt to transplant and rebuild the main means that ligamentaum cruciatum has become the damage for the treatment of ligamentaum cruciatum under the tendon arthroscope.Yet along with patient's continuous increase, the case that the inefficacy of reconstruction ligament appears in postoperative is also increasing gradually.Bibliographical information, the mortality of Healing in Anterior Cruciate Ligament Reconstruction is between 3.6% and 15%.The factor that causes Healing in Anterior Cruciate Ligament Reconstruction to lose efficacy is numerous, and wherein the healing of graft in osseous tunnel is one of successful key factor.Current studies show that, graft in osseous tunnel mobility (rain brush effect and bungee jumping effect) and graft in the tunnel length and the size of osseous tunnel and with the matching degree of tendon be one of key factor that influences the tendon knitting.Scholars find, when adopting the button steel plate to suspend in midair fixedly to graft, it is more long to suspend used line in the osseous tunnel in midair, it is more short to transplant tendon, it is more high then to transplant the suffered tension force of tendon, and " bungee jumping effect " is just more big, reduces " bungee jumping effect " so suggestion reduces the length of osseous tunnel messenger wire.
Current clinical to rebuilding anterior cruciate ligament osseous tunnel size under the arthroscope particularly the foundation of length all be to be undertaken by the segmented property of hard chi (femur and tibial tunnel), the length that the articular cavity internal ligament needs then only can by enuflex position femur and tibia footmark place carry out measure under the arthroscope.May be able to measure relatively accurately to tibial tunnel to the femur tunnel although segmented, the length of tendon then only can be by the carrying out measuring under the arthroscope and add that not matching of knee joint fork ligament injury posterior joint para-position relation all may have influence on the degree of accuracy of measurement of enuflex position femur and tibia footmark place in the knee joint in the articular cavity, and then have influence on not matching of graft and tunnel length.May influence the tendon knitting because of " bungee jumping effect " on the one hand, waste tendon graft on the other hand.
Summary of the invention
The present invention aims to provide in the full tunnel that a kind of ligamentaum cruciatum rebuilds depth measurement and simulates chi, can accurately measure keeping under the full tunnel tension force that carries out osseous tunnel under the situation of tension force, can also measure simultaneously the length of femur, tibial tunnel and knee joint cavity internal ligament, reach the purpose of cutting the garment according to the figure, be conducive to alleviate because of " bungee jumping effect " influence to the tendon knitting, promote the tendon knitting, improve the utilization rate of tendon graft.
For achieving the above object, the present invention realizes by the following technical solutions:
Depth measurement simulation chi in the full tunnel that ligamentaum cruciatum disclosed by the invention is rebuild, it is characterized in that: an end of memory alloy wire and miniature steel plate flexibly connect, its other end is fixedlyed connected with the pulling force shadoof, described memory alloy wire is provided with scale, the two ends of described miniature steel plate are provided with draught line, draw in osseous tunnel when being convenient for measuring.
Preferably, described memory alloy wire is the memory steel wire.
Preferably, described miniature steel plate is the endbutton steel plate.
Preferably, described memory alloy wire is that hinge is connected with flexible connection between the miniature steel plate.
Preferably, the precision of described scale is 1mm.
Preferably, the diameter of described memory alloy wire is 3mm.
Depth measurement simulation chi in the full tunnel that ligamentaum cruciatum disclosed by the invention is rebuild, can accurately measure keeping under the full tunnel tension force that carries out osseous tunnel under the situation of tension force, can also measure simultaneously the length of femur, tibial tunnel and knee joint cavity internal ligament, reach the purpose of cutting the garment according to the figure, maximized reduction " bungee jumping effect ", be conducive to the tendon knitting, improve the utilization rate of tendon graft; Reduce the misery of sufferer, save material, have good social benefit and economic benefit.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure: 1-miniature steel plate, 2-memory alloy wire, 3-scale, 4-pulling force shadoof, 5-draught line.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.
As shown in Figure 1, depth measurement simulation chi in the full tunnel of Healing in Anterior Cruciate Ligament Reconstruction disclosed by the invention, an end of memory alloy wire 2 and miniature steel plate 1 flexibly connect, and its other end is fixedlyed connected with pulling force shadoof 4, memory alloy wire 2 is provided with scale 3, and the two ends of miniature steel plate 1 are provided with draught line 5.
Preferably, memory alloy wire 2 is the memory steel wire.
Preferably, miniature steel plate is the endbutton steel plate.
Preferably, memory alloy wire 2 is that hinge is connected with flexible connection between the miniature steel plate 1.
Preferably, the precision of scale 3 is 1mm.
Preferably, the diameter of memory alloy wire 2 is 3mm.
Operation of the present invention is as follows: under the pulling of draught line 5, miniature steel plate 1 wing drop is parallel with memory alloy wire 2, draught line 5 oral-lateral outside the femur tunnel is drawn out to femur tunnel collar extension from the following of tibial tunnel by tibial tunnel with miniature steel plate 1 and memory alloy wire 2, make miniature steel plate 1 reset to the position vertical with memory alloy wire 2 and fixing then, knee joint again resets, and lift and be positioned at the outer pulling force shadoof 4 of tibia end, read the femur tunnel successively keeping under the situation of tension force on the memory alloy wire 2 of band scale 3, ligament precise length separately in tibial tunnel and the articular cavity, after finishing, linear measure longimetry gently draws an end of miniature steel plate 1, make miniature steel plate 1 become the direction parallel with osseous tunnel, withdraw from memory alloy wire 2 and miniature steel plate 1 again along osseous tunnel from the tibial tunnel collar extension.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
