Description
Technical field
The utility model is related to a kind of for wrapping up the titanium cage of long bone cortex bone ectonexine bone grafting, and in particular to a kind of
The titanium net of arbitrary size package long bone cortex bone ectonexine bone grafting titanium cage can be assembled into, belongs to medical device technology neck
Domain.
Background technology
Long bone of limbs Segmental Bone Defect clinic is common, and package bone grafting is a kind of effective therapy, wherein utilizing titanium net
Package is most common, effect preferably wraps up bone grafting method.
But when being used cooperatively with steel plate, existing common titanium net package bone grafting needs bone-grafting material filling is entire
Wrap device（Titanium cage）It is interior, and long bone pulp cavity position is invalid bone grafting region, because long bone is cylindrical, pulp cavity position
It puts and bone grafting skeletonization is not required, it is only necessary to which skeletonization is therefore existing general with regard to that can complete clinical healing after the bone grafting of cortex of bone position
There are the invalid more defects of bone grafting area for logical titanium net package bone grafting.Titanium cage fusion device is also individual layer titanium net used in vertebra intervertebral fusion
It is rolled into cylindric, bone grafting skeletonization in entire titanium net.
At present, there is not yet only elongated tubular cortical bone site package bone grafting device.
The content of the invention
The purpose of the utility model is to overcome above-mentioned shortcomings, provide a kind of cortical bone site in elongated tubular and wrap up
The titanium cage of cortex bone ectonexine bone grafting, can substantially save bone-grafting material.
The technical solution of the utility model, it is a kind of for wrapping up the titanium cage of long bone cortex bone ectonexine bone grafting, including
Both first titanium net and the second titanium net, the first titanium net and second titanium net are mutually lapped, and are rolled into cylindrical shape；The first titanium net bag
The first titanium net grid and first longitudinal direction protrusion are included, the first titanium net grid is made of crisscross titanium alloy, in the first titanium net net
The one side of lattice is equipped with several columns first longitudinal direction protrusion；Second titanium net includes the second titanium net grid and second longitudinal direction protrusion,
Second titanium net structure is identical with the first titanium net.
First longitudinal direction protrusion and the plane of the second titanium net grid in first titanium net contact with each other, and the of the second titanium net
The two longitudinally convex planes with the first titanium net grid contact with each other.
The length of the first titanium net grid is more than the length of the second titanium net grid, and the width of the first titanium net grid is more than the
Two titanium net mesh widths；When first titanium net is wound into cylindrical shape with the second titanium net, the first titanium net is located at outside, the second titanium net
Positioned inside.
The first longitudinal direction protrusion and second longitudinal direction height of projection are 0.3-0.5cm, and two adjacent first longitudinal directions are convex
Rise or second longitudinal direction protrusion between spacing be 0.6-1.0cm.
First longitudinal direction protrusion with second longitudinal direction protrusion can carry out bending to reduce the first titanium net and the as needed
Spacing between two titanium nets.
The beneficial effects of the utility model：Device provided by the utility model substantially saves bone-grafting material, and double wrapped is planted
The stability of bone material is more preferable compared with individual layer package.Also composable into titanium cage, the big I of titanium cage is arbitrarily reduced；It is pulled longitudinally convex
Tiltedly or bending, the space height of formation just accordingly reduce, and therefore, the gap of package cortex bone ectonexine also can adjust, and be suitble to not
With size bone.

Specific embodiment
As shown in Figs. 1-2, it is a kind of for wrapping up the titanium cage of long bone cortex bone ectonexine bone grafting, including the first titanium net 1
With the second titanium net 2, the first titanium net 1 is mutually lapped with 2 the two of the second titanium net, and is rolled into cylindrical shape；First titanium net 1 includes the
One titanium net grid 1-1 and first longitudinal direction protrusion 1-2, the first titanium net grid 1-1 is made of crisscross titanium alloy, in the first titanium
The one side of net grid 1-1 is equipped with several columns first longitudinal direction protrusion 1-2；Second titanium net 2 include the second titanium net grid 2-1 and
Second longitudinal direction protrusion 2-2,2 structure of the second titanium net and the first titanium net 1 are identical.
First longitudinal direction protrusion 1-2 and the plane of the second titanium net grid 2-1 in first titanium net 1 are contacted with each other, and second
The second longitudinal direction protrusion 2-2 of titanium net 2 and the plane of the first titanium net grid 1-1 contact with each other.
The length of the first titanium net grid 1-1 is more than the length of the second titanium net grid 2-1, the first titanium net grid 1-1's
Width is more than the second titanium net grid 2-1 width；When first titanium net, 1 and second titanium net 2 is wound into cylindrical shape, the first titanium net 1
Positioned at outside, the second titanium net 2 is located inside.
The first longitudinal direction protrusion 1-2 and second longitudinal direction protrusion 2-2 is highly 0.3-0.5cm, two adjacent first
Spacing is 0.6-1.0cm between longitudinally convex 1-2 or second longitudinal direction protrusion 2-2.
The first longitudinal direction protrusion 1-2 and second longitudinal direction protrusion 2-2 can carry out bending as needed to reduce by the first titanium
Spacing between 1 and second titanium net 2 of net.
When the utility model is used, according to needed for cutting out the length and diameter at bone defect position length and width the first titanium
1 and second titanium net 2 of net, wherein, the first titanium net 1 is slightly longer than bone defect length, and the second titanium net 2 is slightly shorter.By the first titanium net 1 and second
The first longitudinal direction protrusion 1-2 and second longitudinal direction protrusion 2-2 of titanium net 2 close up in opposite directions, are then gradually rolled into cylindric, surround a tool
Have the titanium cage in about 0.3-0.5cm height gap, can be previously implanted in gap after bone-grafting material close up again be rolled into it is cylindric.It will circle
Column titanium cage is placed in bone defect position.The bilayer of cylindric titanium cage is corresponding with the ectonexine of limb long tubular bone cortex bone respectively
It is close to wrap up.The new bone close with tubular bone cortex bone position consistency, thickness is just formed after bone grafting skeletonization in gap.
If cortex bone is relatively thin, first longitudinal direction protrusion 1-2 and second longitudinal direction protrusion 2-2 can be pulled to oblique or bending, the sky of formation
Gap height accordingly reduces, and is adapted with relatively thin cortex bone.
