Dissection surface structure design is all used, can realize and be exactly matched with the bone interface of lumbar vertebrae and rumpbone.Upper soleplate layer 112 and prosthese
Top adjacent segment lumbar vertebra connection, lower soleplate layer 113 are connect with the rumpbone of adjacent segment below prosthese, upper and lower soleplate layer
There are many angle and diameter designs, and synosteosis face is designed using anatomic form.Upper soleplate, lower soleplate and adjacent spinal centrum
The faying face of segment uses the porous structure of class bone trabecula and is covered with pyramidal projections, increases initial stage fixed stability, bone at a specified future date
Reach long-term fixation after growing into.For spinal prosthesis 11 using the porous structure of outer category bone trabecula, inside uses entity reinforcing rib knot
Structure designs, and can form the Integrated implant of porous structure and provide good axial compression stiffness.Spinal prosthesis 11 and pedicle of vertebral arch
Screw way 21 is processed using being integrally formed, and the preceding road plate of spinal prosthesis 11 and rumpbone 12 is connected directly, rumpbone screw way 22 and the preceding road of rumpbone
Plate 12 is integrally formed, and not only can guarantee good accuracy, but also can provide better stability.There are plants among Lumbosacral fusion prosthese
Bone hole 114 can carry out bone grafting fusion, realize preferably stability at a specified future date.
The waist sacrum artificial prosthesis of the application can design four nail hole, squeeze into pedicle screw from the front to the back, fix respectively
1 bilateral pedicle of vertebral arch of 5 bilateral pedicle of vertebral arch of waist and sacrum once can be completed to fix in preceding road, the way of escape is avoided to make notch implantation pedicle of vertebral arch again
Nail is fixed.
The structural scheme of mechanism of the application Lumbosacral fusion prosthese is shown in Fig. 1 and Fig. 2.The Lumbosacral fusion prosthese is by seven parts
Composition, upper soleplate layer 112, spinal prosthesis 11, lower soleplate layer 113, the preceding road plate 12 of rumpbone, pedicle screw trajectory 21,114 He of bone grafting hole
22 three parts of rumpbone screw way form；And upper and lower soleplate layer can adjust the anatomic form of different human body by CT data scannings
And size, to adapt to different anatomic physiological data, and realize the Using prosthesis of small wound and small notch.Upper soleplate layer 112, lower end
Plate layer 113 and the faying face of adjacent vertebral use the porous structure of class bone trabecula and are covered with pyramidal projections, and it is fixed to increase initial stage
Stability reaches long-term fixation after Bone Ingrowth at a specified future date.11 part of spinal prosthesis uses external trabecular bone structure, inside to use entity
Reinforcing rib structure designs, and can form the perforation porous structure of Integrated implant and provide axial compression stiffness.Spinal prosthesis 11
With pedicle screw trajectory 21 using being integrally formed, screw way is by corresponding with the anatomical position of CT scan data and structure, Ji Nengbao
The case where demonstrate,proving good stability, and can provide the channel of accurately pedicle screw, reducing injured nerve in art occurs.Rumpbone
Preceding road plate 12 is connected with spinal prosthesis 11, and its structure and moulding meet the physiology anatomical position of CT scan data, in preceding road plate
Anatomical requirements are complied fully with rumpbone binding face.The preceding road plate 12 of rumpbone screw way 22 and rumpbone is integrally formed, the direction of screw way and
Position is determined by the anatomical position of CT scan data completely, it is ensured that accuracy of the sacral screw into nail position.Waist sacrum
