Abstract

The invention provides a tissue repairing patch, which is formed by applying hyaluronic acid film or mixture film of hyaluronic acid and collagen on the surface of high polymer surgical biological patch. The high polymer surgical biological patch is made of artificially synthesized high polymer material. The high polymer surgical biological patch can be prepared by electrostatic spinning process or monofilament spinning process. The patch has improved affinity between biocompatibility and tissue without influencing other biological and mechanical properties and has antibiotic property simultaneously. In addition, filmed-coated patch reduces tissue adhesion and cavum pelvis pain. Moreover, the surgical biological patch has no cytotoxicity and can not cause harm to human bodies.

Description

Surgical repairing patch
Technical field:
The invention belongs to biomedical material, be specifically related to a kind of biology patching material that can in multiple surgical operation, be used for repairing defective tissue or organ.
Background technology:
Artificial material is applied to the main flow that the surgery invasive is repaired has become the modern surgery development.Mainly contain artificial bio-membrane's material and biomaterial two big classes at present.Artificial bio-membrane's material is based on polymer: as terylene, carbon fiber, polyethylene, polypropylene, politef, polylactic acid, polyvinyl alcohol, poly(ethylene oxide), poly-own lactone and polylactic acid-glycolic guanidine-acetic acid etc.; Biological material source has: human body corium, animal membrane tissue, animal corium etc.Though material select to be gone up variation, also reaches certain effect in the practical application, also has various problems, still make great efforts to seek to solve a series of problems after material enters human body at present, as the problem of biocompatibility, the allosome exclusive problem.Desirable material is to realize that stability is high, biocompatibility is good, can induce the fibrous tissue of self to grow into, final support and the fixation that realizes repair tissue.
In recent years, the electro spinning nano fiber material can imitate the structure of extracellular matrix for the preparation of medical surgical sticking patch provides a brand-new solution on the material structure that static is woven into.The natural macromolecular material that makes with electrostatic spinning technique improve biocompatibility and biological activity, but its mechanical strength is difficult to meet the demands.Though and tissue patch elasticity and the intensity of utilizing the absorbable polymer of synthetic such as polylactic acid, polyvinyl alcohol, poly(ethylene oxide), poly-own lactone and polylactic acid-glycolic guanidine-acetic acid etc. to make through electrospinning process can satisfy the demands, but can cause localized liquid to gather, aseptic inflammation is a little less than the biocompatibility relative thin.In order to address the above problem, CN101507843A adopts by collagen protein or/and fibroin albumen or/and polycaprolactone is mixed with mixture by mass percentage, utilizes electrostatic spinning technique to prepare the medical surgical sticking patch with polylactic acid.Though the biology patching material that this method prepares has good biomechanical property and biocompatibility, it does not also have enough universalities.
Though the development of static textile technology, for the application of medical bio sticking patch provides a kind of new selection, but the macromolecular material that some can not absorb, as: polyethylene, polypropylene, politef or its mixture etc., utilize the film-making of static textile technology, also have technical barrier, and the sticking patch of this class material is in some clinical practice field, as also irreplaceable in the Reconstruction at the bottom of the basin.But the macromolecular material that this class can not absorb in actual applications, has the possibility of inserting trouble and latent infection of sticking patch in the operation.
In a word, along with development of science and technology, according to the application characteristic of the present all kinds substitution material of grasping, different tissues, different parts are to the different demands of patching material, the personalized patching material that well-designed manufacturing is suitable.
Summary of the invention:
Deficiency at existing biology patching material existence, the object of the present invention is to provide a kind of surgery biological sticking patch with good biological mechanical property and biocompatibility, and adopt production technology simple, can be made into all size and shape, satisfy the needs of clinical multiple surgical repair operation.
The present invention utilizes hyaluronic acid or hyaluronic acid and collagen protein mixture biological coating technology, in the biomechanical property that does not influence the tissue patch that tissue patch that electrostatic spinning technique makes and monofilament textile technology make, improve biocompatibility and with the affinity of body tissue.And can be made into all size and shape, satisfy clinical multiple demand.
Tissue repairing patch of the present invention is for having hyaluronic acid membrane or hyaluronic acid and collagen protein blend films on the surface of macromolecule surgery biological sticking patch.
Wherein, the thickness of the film of hyaluronic acid or hyaluronic acid and collagen protein mixture is the 2-15 micron.
Wherein, hyaluronic molecular weight is 1,000,000-2,200,000 dalton.
Wherein, the molecular weight 1500-3000 dalton of collagen protein.
Wherein, the material of described macromolecule surgery biological sticking patch is the synthetic macromolecular material.
Wherein, can to absorb macromolecular material be polylactic acid (PLA), polyvinyl alcohol (PVA), poly(ethylene oxide) (PEO), polycaprolactone (PCL), polylactic acid-glycolic guanidine-acetic acid (PLGA) or its mixture to described synthetic.
Wherein, can not to absorb macromolecular material be polyethylene, polypropylene, politef or its mixture to described synthetic.
Wherein, above-mentioned macromolecule surgery biological sticking patch adopts method of electrostatic spinning to make or monofilament weaving method makes.
The preparation method of tissue repairing patch of the present invention is: carry out coating film treatment on the surface of macromolecule surgery biological sticking patch with hyaluronic acid or hyaluronic acid and collagen protein mixture.
Beneficial effect of the present invention:
1, through the sticking patch of hyaluronic acid or hyaluronic acid and collagen protein mixture coating film treatment when not influencing its biomechanical property, improved the affinity of its biocompatibility and body tissue, also have antibiotic property simultaneously, can reduce pain.In addition, sticking patch inserted during the sticking patch behind the plated film was conducive to perform the operation.
2, the surgery that utilizes above method to make biological sticking patch no cytotoxicity can not produce harm to health.
The specific embodiment:
Embodiment 1:
The synthetic macromolecular material is that polylactic acid (PLA), polyvinyl alcohol (PVA), poly(ethylene oxide) (PEO), polycaprolactone (PCL), polylactic acid-glycolic guanidine-acetic acid (PLGA) or its mixture are made the flaky material that thickness is the demand shape of 0.6-1.2mm through static weaving method.Concentration is that the hyaluronic acid solution of 1-3% evenly is sprayed on the above-mentioned flaky material through spray gun, and thickness is the 2-15 micron, namely gets surgery patching material of the present invention after the drying.
Embodiment 2:
The synthetic macromolecular material is that polylactic acid (PLA), polyvinyl alcohol (PVA), poly(ethylene oxide) (PEO), polycaprolactone (PCL), polylactic acid-glycolic guanidine-acetic acid (PLGA) or its mixture are made the flaky material that thickness is the demand shape of 0.6-1.2mm through static weaving method.Be 1-3% hyaluronic acid solution and concentration for after the 1-2% collagen solution mixes with concentration, evenly be sprayed on the above-mentioned flaky material through spray gun that thickness is the 2-15 micron, namely gets surgery patching material of the present invention after the drying.
Embodiment 3:
The synthetic macromolecular material is that polyethylene, polypropylene, politef or its mixture are made the flaky material that thickness is the demand shape of 0.4-1mm through monofilament weaving method.The hyaluronic acid solution that with concentration is 1-3% evenly is sprayed on the above-mentioned flaky material through spray gun, and THICKNESS CONTROL namely gets surgery patching material of the present invention at the 2-15 micron after the drying.
