As shown in Figures 1 to 4, the anchoring device of the present embodiment includes: that anchor plate 20 includes substrate layer 21 and is arranged in base
The microcellular structure layer 23 of 21 inside of plate layer.Anchoring pawl 22 is arranged on the inner surface of anchor plate 20, and specifically, anchoring pawl 22 is arranged
On the inner surface of substrate layer 21.
Using the technical solution of the present embodiment, anchor plate 20 includes substrate layer 21 and is arranged on the inside of the substrate layer 21
Microcellular structure layer 23.Microcellular structure layer 23 has good soft tissue 40 and particulate cancellous bone 40a integration ability.The setting of pawl 22 is anchored to exist
On the inner surface of the anchor plate 20.As shown in Figure 5 and Figure 6, in the present embodiment, anchor plate 20 and anchoring pawl 22 are by soft tissue
40 perhaps particulate cancellous bone 40a be fixed on bone bed 10 and limited soft tissue 40 or particulate cancellous bone 40a and occur outside bone bed 10 loosely
State.In turn, soft tissue 40 or particulate cancellous bone 40a can be fixed on bone bed 10 by anchor plate 20.The structure uses simple
It is convenient.In the present embodiment, microcellular structure layer 23 has preferable Bony union, also has good soft tissue 40 and particle
Bone 40a integration ability.It should be understood that the inner surface of anchor plate 20 is towards the side of bone bed.
Microcellular structure layer 23 and substrate layer 21 can be obtained by 3D printing.Above-mentioned microcellular structure layer 23 forms multiple holes
Gap, similar to trabecular bone structure in the related technology.Bone trabecula in the related technology is extension of the cortical bone in cancellous bone
Point, i.e., bone trabecula is connected with cortical bone.It is in irregular space network in bone network chamber, such as luffa sample or sponge
Shape plays hematopoiesis support tissue.
As shown in Figure 5 and Figure 6, in the present embodiment, the soft tissue on bone bed 10 is dampened in order to prevent, and substrate layer 21 is separate
The surface of microcellular structure layer 23 is polished surface 211.
As shown in figure 5 and figure 7, in order to enable anchor plate 20 to be fitted on bone bed 10, convenient for fixed soft tissue 40, anchoring
The cross section and longitudinal section of plate 20 are arcuate structure.
As shown in Figures 2 and 3, substrate layer 21 and anchoring pawl 22 are made of absorbable material.Substrate layer 21 and anchoring
Pawl 22 is preferably magnesium alloy material.In this way, convenient between substrate layer 21 and anchoring pawl 22 and soft tissue 40 or particulate cancellous bone 40a
Fusion is realized, convenient for the healing of bone bed 10.
In other embodiments, anchoring pawl 22 is made of memorial alloy.When anchoring pawl 22 is implanted into bone bed 10 in this way,
The shape that pawl 22 is anchored under the variation of temperature can deform, so that being anchored, pawl 22 is even closer to be merged with bone bed 10.In turn, anchor
The fixed soft tissue 40 of fixed board 20 and particulate cancellous bone 40a have more preferably synergy.
As shown in Figure 1, in the present embodiment, in order to which the processing of anchor plate 20 is convenient for molding, anchor plate 20 it is edge limited go out
Flat shape be rectangle, specially round rectangle.Preferably, the size B of the length of rectangle is 15mm to 30mm, the ruler of width
Very little A is 10mm to 20mm.
As shown in figure 8, in other embodiments, the edge limited flat shape out of anchor plate 20 is ellipse.Preferably,
The size B1 of elliptical long axis is 20mm to 40mm, and the size A1 of minor axis is 10mm to 20mm.
As shown in Figure 1 to Figure 3, it is entangled on the surface of anchor plate 20 to fix device, anchor plate 20 is far from anchoring pawl 22
Surface on be provided with positioning groove 212.
As shown in Figure 1 to Figure 3, in the present embodiment, in order to wind conveniently, positioning groove 212 can be set to three, and three
A positioning groove is arranged along the length direction interval of anchor plate 20.In other figs. in unshowned embodiment, on anchor plate
The quantity of positioning groove is not limited to three, and quantity can also be two, four or more.
As shown in figure 8, in other embodiments, the quantity of positioning groove is two, anchor plate 20 is far from anchoring pawl 22
Surface on positioning groove be distributed in anchoring pawl 22 between.In this way, the setting of positioning groove will not weaken anchor plate 20 certainly
The intensity of body.
As shown in Figure 6 and Figure 7, anchoring device further includes fixed hawser 30, and fixed hawser 30 and 212 phase of positioning groove are suitable
Match.Fixed hawser 30 is preferably wirerope, and such anchoring device, which is fixed on bone bed 10, becomes more reliable.
As shown in Figures 2 and 3, in the present embodiment, when anchor plate 20 is implanted to load biggish region, such as human body
Lower limb, anchor plate 20 needs certain structural strength, prevents anchor plate 20 from bearing biggish external force and be damaged.Anchor plate 20
Including substrate layer 21 and microcellular structure layer 23, in 3mm between 6mm, the thickness of microcellular structure layer 23 exists the thickness of anchor plate 20
1.5mm is between 3mm.
As shown in Figure 1, in the present embodiment, the quantity of anchoring pawl 22 is four, the setting that anchoring pawl 22 is spaced is being anchored
Plate 20 is towards on the side of microcellular structure layer 23.Particulate cancellous bone 40a or soft tissue 40 can be pressed in the pre- of bone bed 10 by anchoring pawl 22
On phase attachment position.Particulate cancellous bone 40a or soft tissue 40 are between multiple anchoring pawls 22.Unshowned embodiment in other figs.
In, the quantity for being anchored pawl 22 can be two, three, five or more.
As shown in Fig. 2, Fig. 4 and Fig. 5, the center line of anchoring pawl 22 is evagination camber line.Since anchoring pawl 22 is in curved shape, if
Pawl 22 will be anchored from when the extraction of bone bed 10, there can be biggish pull-out resistance.In turn, there is anchoring pawl 22 resistance to plucking to go out bone bed 10
Effect.In this way, particulate cancellous bone 40a and soft tissue 40 can be firmly pressed against on expected attachment position by anchoring pawl 22.
As shown in Fig. 2, Fig. 4 and Fig. 5, anchoring pawl 22 is gradually received on anchor plate 20 to the direction of separate anchor plate 20
Contracting ground extends, and is anchored pawl 22 and forms tip 223 far from one end of anchor plate 20.It is convenient for fixed with bone bed 10 in tip 223.
As shown in Figures 2 and 3, anchoring pawl 22 includes the first segmental arc 221 in its vertical section and is located in the first segmental arc 221
The first end of second segmental arc 222 of side, the first segmental arc 221 and the second segmental arc 222 is connect with anchor plate 20, the first segmental arc 221
It intersects at a point to form tip 223 with the second end of the second segmental arc 222.The segmental arc radius of first segmental arc 221 is preferably for R1
The segmental arc radius R2 of 38.81mm or so, the second segmental arc 222 are preferably 53.31mm or so, so that the shape of the first segmental arc 221
The shape of shape and the second segmental arc 222 more standardizes, in this way, anchoring pawl 22 is convenient in implantation bone bed 10, while having very big
Resistance to plucking goes out the resistance of bone bed 10.
As shown in Fig. 2, the height H that anchoring pawl 22 is pierced by from microcellular structure layer 23 is 5mm-10mm, the first segmental arc 221 and point
Maximum distance T between end 223 is 5mm-10mm or so, and the maximum distance t between the second segmental arc 222 and tip 223 is 1mm-
5mm or so.When anchoring pawl 22 is implanted in bone bed 10 in this way, guarantee the first segmental arc 221 and the second segmental arc 222 in bone bed 10 still
So it is in curved shape, ensure that the ability that anchoring 22 resistance to plucking of pawl goes out bone bed 10.
In embodiment not shown in the figure, it can also be not provided with substrate layer, microcellular structure layer is only set.Anchoring device
When being implanted to the lesser region of load, for example the upper limb of human body, the bonding strength of anchor plate 20 suitably reduce.At this point, anchoring
Plate muscle is formed by microcellular structure layer.Certainly, it is contemplated that processing problems and guarantee certain intensity, the thickness of microcellular structure layer exists
1mm is between 3.5mm.
