Abstract
The utility model provides a novel fixing device of knee joint posterior cruciate ligament shin bone stop avulsion fracture belongs to orthopedic medical equipment technical field, and it needs long -term plaster fixation to aim at solving current knee joint posterior cruciate ligament shin bone stop avulsion fracture postoperative, has the problem of rupture again. The fixed connected bone plate body that it adopted is the fixed connected bone plate body of I -shaped form, S -shaped bent plate face, and the system has even set screw's countersunk head screw of several cooperation dress respectively on fixed connected bone plate body to stub end top transverse arrangement system at fixed connected bone plate body I -shaped form face has the even through -hole of ligament of a 2 -4 dress. Its simple structure is practical, and the postoperative is without plaster fixation, convenience safe in utilization, and the restoration strong fixed and ligament that is applicable to knee joint posterior cruciate ligament shin bone stop avulsion fracture is rebuild.
Description
Technical field
The utility model belongs to the stationary installation of a kind of knee-joint posterior cruciate ligament tibia stop avulsion fracture of orthopedic medical device technical field.
Background technology
Along with improving constantly of the growing of medicine equipment and living standards of the people, the technical requirements of human tibia platform fracture fixation device is also more and more higher. In known technology, rivet that existing human tibia platform fracture fixation device mainly adopts, steel wire, hollow nail+pad, T-shaped plate fixation etc., the fixing mode of former three is insecure, after patient's art and need plaster fixing; And T-shaped plate fixation, often need bending to mould shape in art, reduce the self-strength of Steel Plate For Fixation Of Fracture, there is the possibility fractureed, all make troubles to patient. Also urgently in the stationary installation developing a kind of novel knee-joint posterior cruciate ligament tibia stop avulsion fracture.
Practical novel content
In order to overcome the deficiencies in the prior art, need long-term plaster fixing after solving existing knee-joint posterior cruciate ligament tibia stop avulsion fracture art, there is again the problem fractureed. The object of the utility model is to provide a kind of simple and practical, without plaster fixing after art, there is not the risk fractureed, it is applicable to the reconstruction of the strong fixing of knee-joint posterior cruciate ligament tibia stop avulsion fracture and ligament, recover fracture stabilization, avoid the generation that postoperative ankle is stiff, and new-type fracture of the tibial plateau stationary installation safe and convenient to use.
The technical scheme in the invention for solving the above technical problem is:
The Novel fixing device of a kind of knee-joint posterior cruciate ligament tibia stop avulsion fracture, it is provided with: fixation bone fracture plate main body, set screw, fixation bone fracture plate main body is the fixation bone fracture plate main body in work shape, the curved plate face of S shape, fixation bone fracture plate main body is shaped with heavy head screw that several coordinate load set screw respectively, and the big head end top cross arrangement in fixation bone fracture plate main body work shape plate face is shaped with the through hole of 2-4 load ligament.
The Novel fixing device of above-mentioned knee-joint posterior cruciate ligament tibia stop avulsion fracture, the little cephalic par in described fixation bone fracture plate main body work shape plate face be shaped with 2-3 cephalic par transversely arranged, big be shaped with that 3-4 transversely arranged, plate Middle face is shaped with 1-2 longitudinal arrangement, altogether be longitudinal 3-5 row, the heavy head screw that is total to 6-9 load set screw.
The Novel fixing device of above-mentioned knee-joint posterior cruciate ligament tibia stop avulsion fracture, in the middle part of described fixation bone fracture plate main body body plate, the heavy head screw of longitudinal arrangement is the adjustable heavy head screw of calabash shaped.
The Novel fixing device of above-mentioned knee-joint posterior cruciate ligament tibia stop avulsion fracture, to be main board face be described fixation bone fracture plate main body matches the warped surface type fixation bone fracture plate main body of human tibia nature shape.
The Novel fixing device of above-mentioned knee-joint posterior cruciate ligament tibia stop avulsion fracture, the set screw of little cephalic par load and the set screw of plate Middle face longitudinal arrangement load in described fixation bone fracture plate main body work shape plate face are triangular connection structure.
When the utility model uses, according to design requirements, producing the fixation bone fracture plate main body that patient's shin bone matches, during operation, after directly this novel fixation bone fracture plate main body being placed, set screw in load, can sew up. The set screw of the arbitrary heavy head screw load of the heavy head screw of especially little cephalic par and plate Middle face longitudinal arrangement is that trilateral is fixed; In the big head end through hole of Steel Plate For Fixation Of Fracture, load ligament is used for the establishment reconstruction effect of posterior cruciate ligament of knee, and the tension force after strengthening the fixing stability of posterior cruciate ligament of knee and keeping posterior cruciate function to rebuild, the anatomy recovering knee joint is stablized.
Owing to the utility model design have employed technique scheme, need long-term plaster fixing after efficiently solving existing fracture of the tibial plateau stationary installation art, there is again the problem fractureed. Also show through the result on trial of actual clinical test for several times, it is compared with prior art, have simple and practical, without plaster fixing after art, there is not the risk fractureed, avoid the bending of Steel Plate For Fixation Of Fracture device, mould shape, retain the intensity of Steel Plate For Fixation Of Fracture device, and the advantage such as safe and convenient to use, it is applicable to the reconstruction of the strong fixing of knee-joint posterior cruciate ligament tibia stop avulsion fracture and ligament.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structure diagram of the utility model embodiment.
Fig. 2 is the vertical view of fixation bone fracture plate main body 1 embodiment in Fig. 1.
In accompanying drawing, each label is: 1 fixation bone fracture plate main body; The through hole of 2 load ligaments; 4 triangular connection structure; 3 set screws; 5 ligaments; A 6 heavy screw.
Embodiment
As embodiment illustrated in fig. 2 in accompanying drawing 1-, the utility model is provided with: fixation bone fracture plate main body 1, set screw 3, fixation bone fracture plate main body 1 is work shape, the fixation bone fracture plate main body in the curved plate face of S shape, it is transversely arranged that little cephalic par (i.e. Steel Plate For Fixation Of Fracture body rear portion) in fixation bone fracture plate main body 1 work shape plate face is shaped with 3, it is transversely arranged that big cephalic par (namely Steel Plate For Fixation Of Fracture body is anterior) is shaped with 4, plate Middle face is shaped with 2 longitudinal arrangements, it is longitudinally 4 arrange altogether, the heavy head screw 6 of totally 9 load set screws 3, the hole circle center line connecting of the arbitrary heavy head screw of the heavy head screw of little cephalic par wherein and plate Middle face longitudinal arrangement is the arrangement of trilateral structure, and the big head end top cross arrangement in fixation bone fracture plate main body 1 work shape plate face is shaped with the through hole 2 of 3 load ligaments 5.
