The quantity of the fixing screws is at least three.
Further, the reinforcing member component is double-layer structure, respectively the close to the articular surface side that need to repair
One reinforcing member and the second reinforcing member of the separate articular surface side that need to be repaired；
Multiple threaded holes are offered on first reinforcing member, the fixing screws are distributed in described by the threaded hole
First reinforcing member surface；
The hole depth of the threaded hole is not more than 2/3rds of the thickness of first reinforcing member.
Further, side fixing groove is offered on the two sides of first reinforcing member and second reinforcing member,
It is solid by the connector that connector, first reinforcing member and second reinforcing member are fixed at the side fixing groove
It is fixed.
Further, it is additionally provided with anti-skidding boss between first reinforcing member and second reinforcing member, described first
Reinforcing member and second reinforcing member squeeze the anti-skidding boss.
In the above-mentioned technical solutions, the auxiliary device provided by the utility model for articular cartilage reparation, bilayer are reinforced
Part structure and more screws are fixed, it is ensured that the stability of reinforcing, in addition, the double-deck reinforcing member displacement sliding in order to prevent, also
Connector and anti-skidding boss are devised to firm between reinforcing member, consolidation effect is good, save the cost.
Detailed description of the invention
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, below will be to institute in embodiment
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only to record in the utility model
Some embodiments be also possible to obtain other drawings based on these drawings for those of ordinary skill in the art.
Fig. 1 is the structural schematic diagram of the auxiliary device provided by the embodiment of the utility model for articular cartilage reparation.
Description of symbols:
1, the first reinforcing member；2, the second reinforcing member；3, fixing screws；4, connector；5, side fixing groove；6, anti-skidding convex
Platform.
Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair
The utility model is further detailed.
It is shown in Figure 1；
The auxiliary device for articular cartilage reparation of the utility model, comprising:
Reinforcing member component, reinforcing member component include steel plate part, and the curved shape of reinforcing member component with need to repair
Articular surface matches；
Fixing screws 3, reinforcing member component are fixed with fixed spiral shell on the reinforcing member for the articular surface side that need to be repaired
Nail 3, the tail end of fixing screws 3 is embedded in the reinforcing member；Wherein, the quantity of fixing screws 3 is at least three.
Preferably, reinforcing member component is double-layer structure in the present embodiment, respectively close to the articular surface side that need to be repaired
The first reinforcing member 1 and far from the second reinforcing member 2 of articular surface side that need to be repaired；
Multiple threaded holes are offered on first reinforcing member 1, fixing screws 3 are distributed in 1 table of the first reinforcing member by threaded hole
Face；The hole depth of threaded hole is not more than 2/3rds of the thickness of the first reinforcing member 1.
Specifically, the present embodiment reinforces it using the double-deck reinforcing member structure and three screws, three spiral shells first
Nail surrounds triangular structure, and stability is more preferable, and when being performed the operation, the first reinforcing member 1 of the double-deck reinforcing member is to install fixed spiral shell
Nail 3, and fitting reinforcing is carried out to the articular cartilage that need to be repaired, and play the role of setting off to screw.After patient is used for a long time, such as
Fruit needs replacing, and need to only replace to the first reinforcing member 1 and fixing screws 3, save cost.
Preferably, side fixing groove 5 is offered on the two sides of the first reinforcing member 1 and the second reinforcing member 2, side is fixed
