Description
Technology neighborhood
The invention belongs to Bionic medicine technical fields, and in particular to inhibit bacterial growth and promote the titanium table of protein adherence
Face and preparation method thereof.
Background technique
In field of biomedicine, central venous catheter and Needleless connector, endotracheal tube, intrauterine device, the mechanical heart
Dirty valve, pacemaker, peritoneal dialysis catheters, Tympanostomy pipe, sounding artificial limb, orthopaedic joint prosthesis and percutaneous orthopedic dress
(including external fixator and bone anchor amputation artificial limb) etc. is set, more and more artificial joint replacements change for mitigating patient's pain
Philanthropists' quality of the life.
Titanium have with the good compatibility of human body cell, thus for however transplanting in the transfer operation of man-made organ
The reason of operative failure is often resulted in operation is exactly that biomaterial is infected by bacterial, once bacterium is integrated to biomaterial table
Face, function will change.More specifically, gene expression changes, and growth rate changes, and host defense mechanism no longer can
It is enough to remove them from internal, and the biomembrane of antibiotic-resistant is formed, the development of this biomembrane is to cause many chronic senses
The reason of dye.
In addition, antibiotics resistance bacterial strain with antibiotic treatment cannot be used after surface adhesion.It is common more in clinical orthopaedics
Kind drug-fast bacteria includes staphylococcus aureus and staphylococcus epidermis.Accordingly, it is believed that preventing bacterial adhesion (without using medicine
Object) it may be one of the best way, to reduce orthopaedics implant infection.Application number 201510024331.3 discloses a kind of table
Face micro-patterning antimicrobial surface antibacterial film utilizes electron beam lithography, the removing of electron beam deposition glue, reactive ion etching, hotting mask pressure
A series of micro-processing technologies such as print, production surface have polyethylene, polystyrene, the polyethylene terephthalate of micro-nano structure
The materials such as vinegar, polylactic acid.Manufactured micro-nano structure includes rice font, stripe, dot matrix type, and demonstrates the film of this class formation
Material has good anti-microbial property.
After environment contacts in implant and living organism, first happens is that protein is in the non-specific of implant surfaces
Property absorption, be broadly divided into three processes: protein molecule in body fluid to material surface spread it is close, attach and structural rearrangement after
Desorption.With the continuous deepening of research, construct on the surface of the material in recent years pattern structure (or topological structure) with observe with
The interaction of protein becomes hot spot.Firstly, the pattern structure that material surface is constructed directly affects roughness and surface
Product, this will provide more adsorption sites and proteins interaction;Secondly, the geometric dimension and shape of pattern can be to not
It is made a significant impact with the absorption quantity of protein species and variation of conformation etc..The protein molecular of different sizes and shape
It is capable of the patterning on specifically identification material surface, i.e., is selected along the width of certain geometric dimension and the groove of depth
Adsorb to property.
Titanium surface TiO2The building of nanotube micro-patterning not only increases the roughness of original surface, more creates multistage
Roughness, and then the adsorption capacity of protein is largely improved, in the fusion process for promoting implantation material and surrounding tissue
In, titanium surface hydrophilic part is preferentially adhered to by histocyte, and hydrophobic part has good antibacterial adhesive capacity, to effectively press down
The adherency growth of surrounding bacterial is made.
Prevent bacterial growth and the peculiar surface texture of promotion protein adherence from just seeming by preparing to have in titanium sheet
Particularly important, the present invention is prepared on the surface of titanium sheet with strip and netted micro- by method that ultraviolet catalytic etches
Patterning, compared with prior art, without expensive laboratory apparatus, micro-patterning is easily achieved, the addition of no nano antibacterial agent,
