The constitutional features of uniqueness of the present invention and biomechanics characteristic
Each counter direction jet trays self is guider, for the sterie configuration of guide pin or drill bit location and the many nails of optimization provides " accurate positioning and guiding mould ".
In embodiment one, two, three, two groups of screws, 30 ��-60 �� angle differences are by 130 ��-150 �� oblique holes " cross over fracture line wide-angle cross lock gusseted ", are that femur is near, far-end, sterie configuration that proximal humeral fracture optimization is the most stable.
150 �� " tiltedly wearing by force nail " are close to fracture line inside femur, and the continuity rebuilding cortex of bone achieves powerful leap support, effectively stops the varus displacement of fracture, it is achieved the quiet power on theory of structures is stable, has the unique function of " standing tree top is very heavy ".
Band heavy head design in �� 7 oblique hole is fixing with �� 7 vertebra bar pressurization screw " microgap riveted ", and M5 forms " interconnection locking " and achieves " very locking " after locking the head of a nail and os integumentale screw crown pressure, have the anti-varus effect that DHS sleeve is equally powerful.
�� 7 tiltedly fix by the heavy head design of hole band and �� 7 vertebra bar pressurization screw " microgap riveted ", have and lock the more reliable anti-varus effect of plate than " AO ", eliminate again the fatal structure and function defect that can not realize in " false locking " and art between nail-plate sliding and pressurizeing simultaneously.
Embodiment 44 �� 7 sink the head constant spacing of oblique hole diamond array makes steel plate not divide left and right and optimize the sterie configuration of many nails, makes every piece of screw can play respective maximum mechanical function, jointly realizes Whole power and stablize maximumization.
�� 7 vertebra bar screw instead of nail-plate lock function locked the head of a nail and os integumentale screw crown pressure by M5 after, prevent the generation moving back nail, " interconnection locking " achieves " really locking ", eliminate the textural defect that between nail-plate, " the false locking " of locking is fatal, remain again reset function of pressurizeing in the art of pressurization screw simultaneously.
The interconnection locking of sterie configuration three dimensional intersection of optimization " the constant spacing of many nails with " pressurization of sliding after effectively stoping art rotates and unstable occurs harmful stable realizing relative quiet power and fixing for two times.
Embodiment five, six is by the parallel of 135-160 �� of angle or intersects at sliding mortise or tiltedly tiltedly wears nail by force in hole, it is close to stock dry inner side fracture line, the continuity rebuilding inner side cortex of bone realizes powerful leap support, can effectively resist the stress of inner side cortex of bone, thus reduce the folding s tress of steel plate, help steel plate together by power. 13 two pieces are followed closely by diameter 6.5 perfect thread, 135-160 �� of intersection or two pieces of parallel fixing rear screws resist folding s tress at first, counter direction jet trays is prevented to fracture structure He in biomechanics, the design of constant in a kind of embodiment five wherein oblique hole is accurate in order to entrance point of screw, and the design of embodiment six chute is also to be precisely accurate under free prerequisite. accurate unrestricted choice space is left to doctor's operation, appropriately select precisely and freely to take into account mutually according to classification of fracture and classical principle, the unique effect of chute is that screw precisely enters a little and the unrestricted choice handled easily in direction prevents stress from concentrating a bit, wherein the screw in chute not only has fixation steel plate effect, also realize the dual function of fixing fracture simultaneously, the first broken nail screw of disconnected plate is flexible, so the 2-3 piece of long spiro nail that diameter 6.5 or footpath, �� 7 end are 5 crosses over fracture line two ends resists folding s tress at first, fractureing of steel plate is prevented from structure and biomechanics, solve backbone, femur is near, often there is the global problem of disconnected plate broken nail in far-end and proximal humeral fracture " stress that AO locks plate is concentrated ".
The present invention's formation has three-dimensional anti-rotation and anti-varus effect, and is the space structure that Methods for Distal Femoral Fractures optimization is the most stable. By tiltedly wearing nail is close to fracture line inside femur by force, the continuity rebuilding cortex of bone realizes powerful leap support, effectively stops the varus displacement of fracture, it is achieved the quiet power on theory of structures is stable. Cross over fracture line two ends by lock nail and resist folding s tress at first, undertake part stress by screw, structure and in biomechanics, solve backbone, femur is near, disconnected plate often occurs in distal humerus fractured near end " stress that AO locks plate is concentrated " world-famous puzzle.
