The connection depth of humerus increases, and increases the tightness of fixed plate body, on the other hand, since the recess on hole edge leads to fastener
To the less of the pressure increase of fixed plate body, to slow down the pressure that humeral head is subject to, the normal healing of humerus ensure that.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the utility model for the fixed device of humeral head of osteoporotic bone；
Fig. 2 is the schematic cross-sectional view in Fig. 1 along line A-A.
Specific embodiment
The fixed dress of humeral head to the utility model for osteoporotic bone with reference to the accompanying drawings and detailed description
It sets and is described in further detail:
As depicted in figs. 1 and 2, in this embodiment, the utility model is used for the humeral head of osteoporotic bone
Fixed device, including fixed plate body 1, fixed plate body 1 include being located at the upper arm with the curved slab 101 and fitting for being bonded humeral head
The diaphyseal plate 102 of the humerus backbone of bone lower head, in the present embodiment, the length of diaphyseal plate 102 is 4cm.Diaphyseal plate 102 and song
The junction of panel 101 is bonded the link position of humeral head and humerus backbone, is distributed with several first around curved slab 101
The middle part of kirschner pin hole 2, curved slab 101 is equipped with 6 the first locking holes 3.The portion of diaphyseal plate 102 is furnished with second kirschner
Pin hole 4, there are two the second locking holes 5 for distribution in the horizontal direction in diaphyseal plate 102, and diaphyseal plate 102 is in the lower section of the second locking hole 5
There are two holes 7 of pressurizeing for distribution along the vertical direction.Pressurization hole 7 includes strip section and inclination hole section, strip section and inclination hole section phase
It hands over, a circle groove 6 is equipped on 7 inner wall of hole that pressurizes, the lateral surface of the diaphyseal plate 102 of the two sides cell wall and corresponding position of groove 6 is flat
It goes, silica gel 8 is filled in groove 6, since silica gel 8 has elasticity, when pressurization hole 7 is pressurized, silica gel 8 can absorb pressure
Power further slows down pressure.
6 first locking holes 3 of the utility model are angling hole, and 6 the first locking holes 3 are in irregular distribution
At the middle part of curved slab 101, section of the axis of 6 the first locking holes 3 with curved slab 101 at corresponding first locking hole 3
Between angle be respectively 85 °, 80 °, 75 °, 70 °, 65 °, 60 °.It, can be preferably to humeral head using this fixed form
It is fixed, is conducive to the recovery of humerus.In addition, the two sides of the utility model curved slab 101 and diaphyseal plate 102 are close to bottom
The two sides at place are respectively equipped with the flange 9 of package humeral head and humerus backbone, and flange 9 is equipped with third kirschner pin hole, can
In fixed fixed plate body 1, play the role of being fixed temporarily, in order to the first locking hole 3 and bone on subsequent curved slab 101
The fixation of the second locking hole 5 on dry plate 102.
When the utility model is used, when being inserted into fastener in pressurization hole 7, when increasing pressure, due to the hole wall in hole 7 of pressurizeing
Place opens up groove, and therefore, the hole in hole 7 of pressurizeing is along can be recessed inwardly, in this way, on the one hand due to the fastening end of fastener and humerus
It connects depth to increase, increases the tightness of fixed plate body 1；On the other hand, since the recess on hole edge causes fastener to solid
The pressure increase of fixed board body 1 it is less, to slow down the pressure that humeral head is subject to, ensure that the normal healing of humerus.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
