Abstract
The utility model discloses cruciate ligaments of knee joint to rebuild epiphysis Suspending fixation device, the epiphysis Suspending fixation device includes that one piece of circle has button-shaped ontology (1) made of the titanium alloy material of male and female face, at the center of button-shaped ontology (1), symmetry is opened there are two oval long hole (2) and two round holes (3) up and down, and in the land edges of button-shaped ontology (1), symmetry is equipped with dentation (4) up and down.The utility model structure is simple, easy to operate, practical, is conducive to patient and gets well as early as possible.
Description
Technical field
The utility model belongs to field of medical technology, and in particular to a kind of cruciate ligaments of knee joint reconstruction epiphysis Suspending fixation
Device.
Background technique
It is well known that having deep love for the people of movement increasingly with traffic and the prosperity of industry, the raising of human living standard
More, injury of cruciate ligament of knee joint patient is also more and more.Cruciate ligaments of knee joint reconstruction technique is carried out under arthroscope at present
The standard art formula for the treatment of injury of cruciate ligament of knee joint is had become, ligament reconstructive must be related to bone both ends fixation problem, which kind of is solid
Determine that method clinical effectiveness is optimal to have always dispute.Especially ligament tibia end always exists following a few class problems in clinical practice:
1. fixation is less firm, graft contacts not close with bone road, is easy to appear " rain brush effect "；2. tendon graft diameter is too
Carefully, it is easy to be broken again during ligamentization, is not able to satisfy the big people's demand of amount of exercise；3. to do thick graft, graft occur long
Degree is too short, cannot draw ligament tibia end collar extension completely, and squeezing effect is bad, is easy to loosen failure；4. cannot accomplish strong fixation, tendon
Knitting is slow or bad, and there are the risks that graft during postoperative rehabilitation is pulled loose failure；5. in order to avoid graft loosening,
Need increasing No.1 interference screw to be screwed into tibial bone road in operation, graft has the risk for being squeezed cutting by interference screw sometimes.
Summary of the invention
In view of the deficiency in the presence of the prior art, the purpose of this utility model is to design a kind of cruciate ligaments of knee joint weight
Epiphysis Suspending fixation device is built, structure is simple, and it is easy to operate, it is practical, be conducive to patient and get well as early as possible.
In order to achieve the above-mentioned object of the invention, the technical solution that the utility model is taken is: the knee joint intersects tough
It include that one piece of circle has button-shaped ontology made of the titanium alloy material of male and female face with epiphysis Suspending fixation device is rebuild, in knob
Symmetry opens that there are two oval long hole and two round holes up and down at the center of button ontology, on the convex surface of button-shaped ontology
Symmetry is equipped with dentation up and down at edge.
Further, the diameter dimension of button-shaped ontology is 14mm.
In use, button-shaped ontology is stuck on the sclerotin of bone road collar extension by the dentation of land edges, former shin bone
The extrusion screw at end can be screwed into bone road internal orifice in advance, and combine progress ligament tibia end to fix both itself and extrusion screw, by knob
The braided suture intersection at graft end is pierced by knotting and fixed by the oval long hole of two of button ontology and two round holes, is realized
The dual fixation of ligament tibia end, while the dentation on ontology can prevent the sliding of button-shaped ontology during limb activity.
The utility model has the advantage that 1, graft, using dual fixation, fixes more firm stabilization in ligament tibia end,
Graft saves tendon without pulling out tibial bone road collar extension in this way；2, graft is made into 6 strands or 8 strands, diameter accomplish 9mm or
Person 10mm reaches better clinical effectiveness to kneed rotational stabilization to be not easy to be broken again during opisthodetic ligamentization, Gu
It is fixed strong, it is not easy to loosen failure, be in close contact tendon bone, and be conducive to tendon-bone healing, can effectively weaken rain brush and spring
Extremely equal ill effects；3, its of simple structure and strong practicability is conducive to patient and gets well as early as possible；4, this can also be used in femur end
Fixed device Suspending fixation, avoids clinically that femur bone road is too short, be not easy to turn over loop, bone road collar extension is drawn quick-fried risk.
Detailed description of the invention
Fig. 1 is the three dimensional structure diagram of the utility model.
In figure: 1 button-shaped ontology, 2 oval long holes, 3 round holes, 4 dentations.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawing.
As shown in Figure 1, it includes that one piece of circle has male and female face that the cruciate ligaments of knee joint, which rebuilds epiphysis Suspending fixation device,
Titanium alloy material made of button-shaped ontology 1, the center of button-shaped ontology 1 up and down symmetry open there are two ellipse
Long hole 2 and two round holes 3, button-shaped ontology 1 land edges up and down symmetry be equipped with dentation 4.
Further, the diameter dimension of button-shaped ontology 1 is 14mm.
In use, button-shaped ontology 1 is stuck on the sclerotin of bone road collar extension by the dentation 4 of land edges, former shin
The extrusion screw of epiphysis can be screwed into bone road internal orifice, and combine progress ligament tibia end to fix both itself and extrusion screw, by button
The braided suture intersection at graft end is pierced by knotting and fixed by the oval long hole 2 of two of formula ontology 1 and two round holes 3, tooth
Shape protrusion 4 can prevent the sliding of button-shaped ontology during limb activity.
