Be with the shortcomings that titanium film: titanium film is bent after moulding, has elastical retraction phenomenon, causes the change of implantation object space；Also, it needs
It to perform the operation again and take out titanium film and screw.
Utility model content
The purpose of the utility model is to provide a kind of absorbable thermoplastic shape plate, to solve above-mentioned of the existing technology ask
Topic, enables moulding plate to be absorbed, without performing the operation again.
To achieve the above object, the utility model provides following scheme:
The utility model provides a kind of absorbable thermoplastic shape plate, including plate body, and being provided on one side for the plate body is several
Protrusion is provided with several through-holes on the plate body, and the position of the through-hole is corresponding with the protrusion, the absorbable thermoplastic shape
Plate is made of polylactic acid integrated molding.
Preferably, the two sides of the plate body is rough surface, and roughness Ra is 1.6-3.2 μm.
Preferably, the length of the plate body is 5-35mm, and the width of the plate body is 5-25mm.
Preferably, the protrusion is strip, and is uniformly arranged along the length direction of the plate body.
Preferably, the height of the protrusion is 0.1-1mm.
Preferably, the size of the through-hole is 1.5-7.5mm, and the size of the through-hole is greater than the width of the protrusion.
Preferably, the through-hole is arranged in several protrusion lower end intervals.
Preferably, the cross section of the protrusion is round, triangle or rectangle.
The utility model achieves following technical effect compared with the existing technology:
The absorbable thermoplastic shape plate of the utility model is made of polylactic acid integrated molding, is using preceding carry out plasticity, and
And polylactic acid is absorbable material, after thermoplastic shape plate completes function, degradation in vivo reduces and suffers from without carrying out second operation
The pain of person avoids bone injury caused by second operation.The utility model is provided with through-hole and protrusion, and through-hole can be such that blood supplies
Answer smooth, protrusion provides space for the growth of cell, avoids thermoplastic shape plate and is close to blood supply obstacle caused by bone material
And dysfunctional cell growth.Plate body is rough surface, blends absorbable thermoplastic shape plate with tissue.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to this
A little attached drawings obtain other attached drawings.
Fig. 1 is the absorbable thermoplastic shape plate schematic diagram of the utility model；
Wherein: 1- plate body, 2- protrusion, 3- through-hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are in the premise not made the creative labor
Under every other embodiment obtained, fall within the protection scope of the utility model.
The purpose of the utility model is to provide a kind of absorbable thermoplastic shape plate, to solve above-mentioned of the existing technology ask
Topic, enables moulding plate to be absorbed, without performing the operation again.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
A kind of absorbable thermoplastic shape plate, including plate body 1 are present embodiments provided as shown in Figure 1:, and the length of plate body 1 is 5-
35mm, the width of plate body 1 are 5-25mm.The two sides of plate body 1 is rough surface, and roughness Ra is 1.6-3.2 μm, and rough surface makes
Absorbable thermoplastic shape plate is blended with tissue.
In the present embodiment, plate body 1 is provided with several protrusions 2, preferably six on one side, and protrusion 2 is strip, and along plate
The length direction of body 1 is uniformly arranged.The length of protrusion 2 is of same size with plate body 1, and the height of protrusion 2 is 0.1-1mm.Protrusion 2
Cross section be round, triangle or rectangle, preferably triangle.Protrusion 2 provides space for the growth of cell, avoids heat
