Detailed description of the invention
Embodiment, refers to shown in Fig. 1 to Fig. 4, and on rear side of a kind of distal tibial of the present utility model, anatomical form lockplate is made up of integrated head 1 and body 2, and definition has the bottom surface a for contacting tibia and relative end face b.Body 2 is straight tabulars, and the width of head 1 is greater than body, by body 2 length direction one far-end outwards and extend and the arc shape formed along its width torsional bending to end face direction is.
Head 1 is provided with some lock holes 11, body 2 is arranged with some combined holes 21 along its length.Combined hole 21 is 8 font structures formed by the sliding eye 211 interconnected and screwed hole 212, and screwed hole 212 is near far-end and be provided with female thread with suitable with lock screw, and the inner surface relative smooth of sliding eye 211 is with suitable with os integumentale screw.The bottom surface a lateral symmetry of body 2 is arranged with the depressed part 22 of some part indents formation.
With reference to figure 2 and Fig. 3, head 1 is stretched out by body 2, limit, the left and right sides is along its length formed by arc and the smooth connection of body 2 side respectively, wherein limit, left side is outwards formed by left inside concave arc line segment 12, the smooth connection of left outside convex arc line segment 13, right edge is outwards formed by right inside concave arc line segment 14, the smooth connection of right outside convex arc line segment 15, reduces after the width of head 1 is outwards expanded gradually.With reference to figure 4, the radian change of left inside concave arc line segment 12, left outside convex arc line segment 13 is greater than right inside concave arc line segment 14, right outside convex arc line segment 15 respectively, head 1 by right side to left side to end face b direction torsional bending, form the circular-arc bottom face of evagination, to meet the anatomical structure on rear side of distal tibial, docile Du Genggao.The blunt process of circle that the far-end of head 1 slightly inside contracts simultaneously facilitates in art better inserts, fixing more solid and reliable.
Head 1 is provided with 4 lock holes 11, in trapezoidal profile, wherein 2 lock holes 11 are positioned at its maximum width of head 1, coordinate clavicle screw to lock, make structure more stable with rational layout.
Preferred as one, equidistantly on body 2 be arranged with 9 combined holes 21, combined hole 21 adapts to and adds nail pressing, pulling force nail and locking nail, pressurization and locking in art is facilitated to fix, the structure of its figure of eight is convenient to prevent screw to be shifted, and the class support effect that plate and nail are combined forms angulation stable interface.In addition, depressed part 22 is arranged at the both sides on a of bottom surface between adjacent combined hole 21, with combined hole 21 Heterogeneous Permutation, forms Limited contact, effectively reduces the compressing to periosteum, and protection blood fortune, promotes union of fracture, reduce the generation of the complication such as infection.
The end face b of body 2 is planes, and bottom surface a is the arc surface of evagination, and the near-end relative on length direction of body 2 is provided with chamfering, makes it more mate with Tibia Anatomy shape, reduces friction and compressing further, is beneficial to the carrying out of Minimally Invasive Surgery.
Preferred as one, the width of body is 13-18mm, and the Breadth Maximum of head is 30-35mm.
Above-described embodiment is only used for further illustrating anatomical form lockplate on rear side of a kind of distal tibial of the present utility model; but this utility model is not limited to embodiment; every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all fall in the protection domain of technical solutions of the utility model.
