Abstract
The utility model discloses a structure for spine rebuild reductor that is implanted in the spine. The outer diameter of the repository enlarges from the first end to the second end and the surrounding wall side of the repository takes the shape of arc convexity. At the same time, the surface of the repository is distributed with grain with different sizes to form a rugged face. The head face of the second end of the repository is provided with an inner screw hole which retreats toward the first end so as to insert the repository into the hurt spine which will be expended for reposition.
Description
Technical field
This utility model relates to the structure that a kind of vertebra is rebuild positor, refer to especially a kind of can be at the treatment of repressive vertebral fracture, burst vertebral fracture, osteoporosis, when improving, employed positor structure innovation design.
Background technology
The women of menolipsis all has osteoporosis to a certain degree, and men age also has identical problem when big; And so-called osteoporosis is owing to calcareous by running off in the skeletal tissue, causes osteopenia, makes skeleton loosen, become fragile, die down, and fractures easily, and this kind phenomenon is obvious especially at vertebrae.
The risk factor of osteoporosis has:
1. ethnic: Black people's bone density is higher, and white man and yellow's bone density are lower, easily suffer from osteoporosis.
2. lifestyle: smoke excessive drinking, excessive coffee for drinking, tea, hypomotility or excessive.
3. heredity: the family history person that osteoporosis is arranged.
4. medicine: life-time service steroid, thyroxine, diuretic, tetracycline, contain aluminum antacid and chemical small house method at heparin, antuepileptic, Li salt, antagonist.
5. gonad function: male's property line insufficiency of function, women's naturality or because of the early onset menolipsis person due to the operation.
6. sex, body constitution, age: the women is later for 6 to 8 times of the male, build slight of stature, menophania, nullipara and age are healed big person.
When tradition is used for treating the fracture of osteoporosis and vertebrae thereof, can be divided into two kinds of modes, one fixes for making steel nail from the vertebrae rear, and another is for to fix from vertebrae the place ahead kind bone.Yet, beat the fixed mode of steel nail from the vertebrae rear, usually must fixing last two joint vertebras and two joint vertebras down, so a joint vertebra is injured, must sacrifice the mobility of five joint vertebras, cause that the vertebra post is stiff, activity is dumb; In addition, former sclerotin is loose, and the vertebral body of fracture stays next macroscopic-void after resetting, if do not repair, the steel nail of depending merely on the rear fixedly is unsteady, sometimes even can cause and become flexible and rupture, causes operative failure.As for mend the fixed mode of bone from vertebrae the place ahead, then because of need undergo surgery via thoracic cavity or place, abdominal cavity, so, may injure near organ [as pulmonary and blood vessel etc.]; And the time that this operation is spent is also longer, simultaneously, need get rib or use donations bone, and infected problem is arranged, and in addition, this mode equally also has the problem of sacrificing vertebra post mobility.
Summary of the invention
The purpose of this utility model is to provide a kind of vertebra via vertebra stem implantation vertebral body to rebuild the structure of positor, and this positor is implanted the injured vertebral body that should save, can not injure other healthy vertebral bodys.
For achieving the above object, this utility model adopts following design: a kind of structure of implanting the vertebra reconstruction positor of vertebral body via the vertebra stem, it is characterized in that: the external diameter of this positor from first end toward second end by little gradually big, and wall also is slightly convex arc-shape around the positor, simultaneously, surface at positor has been covered with particles with different sizes, and to form matsurface, the end face in positor second end is provided with towards the recessed inner bolt hole of first end again.
Advantage of the present utility model: the vertebra that this utility model is implanted vertebral body via the vertebra stem is rebuild the structure of upright device again, this positor is that an external diameter is by little gradually big longitudinal bodies, its surface is rough-shape, and slightly arc is protruding for wall all around, to utilize this positor to embed in this injured vertebra, make this vertebra be subjected to expanded support and reset, can not injure other healthy vertebral bodys.

Fig. 2: user mode sketch map of the present utility model.
Fig. 3: another user mode sketch map of the present utility model.
The specific embodiment
At first, see also shown in Figure 1, positor 1 of the present utility model is applied under vertebral body 2 states more complete, that need not adjust, it is a longitudinal bodies, and its external diameter from first end 11 toward second ends 12 by little gradually big, and positor 1 around wall 13 also be slightly convex arc-shape, simultaneously, and the surface of this positor 1 has been covered with particles with different sizes, to form matsurface, is provided with the inner bolt hole 14 that is recessed into towards first end 11 again in the end of positor 1 second end 12.
When its desire embeds the vertebral body 2 of vertebra (as shown in Figure 2), be drilled with an implantation hole 22 that can cooperate earlier with positor 1 from vertebra stem 21 places of vertebral body 2, then, inner bolt hole 14 with specific implanting instrument and positor 1 is spirally connected again, and instrument is implanted positor 1 in the implantation hole 22 of vertebral body 2 by this, after waiting to withdraw from implanting instrument, inserts from body bone again or manually substitutes bone, so, this positor 1 can be fixed in the vertebral body 2.
The design focal point of this positor 1 is to design according to the anatomical structure of vertebra stem 21, and vertebra stem 21 its longitudinal sections are to be situated between between ellipse and the rectangle, and is big up and down, the left and right sides is less.The height of vertebra stem 21 accounts between the 50%-60% of vertebral body 2 height, so if can press its size design, implant the vertebral body positor by vertebra stem 21, the 50%-60% that can reset at least adds residual vertebral body 2 bones, then can arrive 70%-80%.
Moreover, injured vertebral body 2 that should joint after implanting positor 1, visual sufferer situation, again between the last joint of this joint vertebral body 2 and next joint vertebral body 2 with nail 3 auxiliary fixing (as shown in Figure 3), the degree of stability of increase vertebra.
Because this positor 1 burrows via vertebra stem 21, under the situation that does not need by abdominal cavity or thoracic surgery, be implanted in the vertebral body 2 that osteoporosis becomes fragile, dies down, so can increase the intensity of vertebral body 2 in view of the above; Simultaneously, be the slightly characteristic of convex arc-shape by wall 13 around this positor 1, can outer top expanded support vertebral body 2, add implantation from the body bone or manually substitute bone, to keep the normal height and the width of vertebral body 2; In addition, because of the surface of this positor 1 is the matsurface that is covered with the protruding grain that varies in size, so, can help bone growth, also can increase the degree of stability that vertebral body 2 bones engage; And this positor 1 is implanted the injured vertebral body 2 that should save, can't injure other healthy vertebral bodys 2.
In sum, this utility model embodiment really can reach desired use effect.
