Avoid due to the injury that operating time is long, otch is caused greatly to patient.
Reservation articular surface type assembly type Femoral quality knee-joint prosthesis of the present utility model have following design feature：
(1) the individuation custom design of DF prosthese and movable lockplate：Due to the individual difference and disease of patient
Become the difference in region, the condyle of femur size of DF, osteotomy site and osteotomy surface shape, the diameter of patient femur, turn up
Angle all can be different, in order that prosthese can obtain satisfied matching degree with the bone of patient's member-retaining portion, it is closely possible to subtract
The forfeiture of few articulation structure and recovery limb function, the correct line of force of holding suffering limb are, it is necessary to DF prosthese and active lock
Fixed board carries out individuation custom design.With Digital Medicine Technology deepening continuously and expansion in clinical treatment field, tradition doctor
Learn the modern medicine direction just towards precision, personalized, minimally invasiveization to develop, DF prosthese in the utility model sets
The method for designing of this modernization is exactly applied to meter thinking the result of clinic；DF prosthese of the present utility model is root
Imported into according to the CT/MRI data of patient carries out biology and rebuilds in MIMICS (interactive medical image control system) software
To designing a model for prosthese, then melted using electron beam or laser 3D printing technology and Numeric Control Technology are processed and obtain and patient
The consistent customization prosthese of femur anatomical data, accurate osteotomy is carried out under being guided using computer navigation in installation of performing the operation, then
Load onto matched measure prostheses；The movable lockplate size design being connected with DF prosthese is also completely according to trouble
The CT/MRI mathematical models of person optimize design and obtain, and have 6 holes on plate, wherein 3 holes are stepped unthreaded hole, using solid
Mode connects for screw is determined on DF prosthese, and 3 holes in addition are conical screw hole, and femur is connected to using locking bone screw
On condyle, accurately punched mounting screw by sight device in art, its precision can reach complete with the condyle of femur of member-retaining portion
Full matching, dissects contraposition accurate；
(2) taper fit and the Interface design with anti-rotation draw-in groove：Between each prosthetic component provided by the utility model
Using 1 commonly used in engineering:20 taper fits and anti-rotation draw-in groove connected mode, the maximum mechanics feature of this connection can be
The stress conversion that any direction will be subject to is the extruding force perpendicular to the conical surface, particularly in loading by lower limbs, two parts of prosthese
Component connects the bigger connection of even closer reliability, i.e. pressure in the presence of compression and more fastens, and is exactly in addition anti-rotation draw-in groove
Design can eliminate prosthese two parts component relative torsion diametrically, so as to avoid to greatest extent due between part
Relative twisting movement and the joint mobilization that causes；
(3) assembly type design：Customized type, i.e. prosthese producer are used the tumour articular prosthesis for using at present to be needed according to doctor more
The raw key pulp cavity diameter for providing, the remaining data such as pulp cavity length and pre-cut bone tumour length are made, after making again
Performed the operation.But often occur in art because pulp cavity inner diameter measurement is inaccurate, bone tumour needs the emergency cases such as expanded scope, and customize
Formula can not flexibly be strained and cause operative failure.For this problem, the utility model provides a kind of key extension of assembly type
Section and femoral bone cavitas medullaris prolonging handle prosthese, this prosthese can be by medullary cavity extension handle different-diameter and length and key extensions not
Selected come the Cranial defect demand of the individual difference and diverse location for meeting backbone with any assembling of length；
(4) bone trabecula loose structure design：DF prosthese of the present utility model and movable lockplate, its prosthese and bone
The end face that epiphysis connects is provided with the thick bone trabecula loose structures of one layer of 1-5mm, and this structure is similar to the microcellular structure of human body cancellous bone,
Micropore is interpenetrated, and blood supply is grown into beneficial to Bone Ingrowth and blood vessel attachment, enhances biological fusion fixed effect；
(5) biological painting designs：DF prosthese of the present utility model and movable lockplate, the lockplate on its prosthese
Inner surface (be in contact position with patient femur's condyle) carries out biological spray treatment (spraying Ti or HA or tantalum coating in surface), can be bone
And soft tissue provides good growing environment and excellent biological fixation, syncretizing effect.
In such scheme, the utility model can retain articular surface, retain epiphysis and surrounding ligaments tissue, be closed knee is retained
Also ensure the bone uptake function of child patient while section motor function, and DF prosthese in the utility model with
And, beneficial to Bone Ingrowth, form long-term biology solid with bone trabecula loose structure on the end face be close to epiphysis of movable lockplate
Determine effect, extend the service life of prosthese, simple structure, using, it is easy for installation.
The above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
