Abstract
The utility model relates to an absorbable magnesium alloy staple used for an anastomat which includes a U-shaped body; the U-shaped body is a U-shaped magnesium alloy wire and a surface coating with excellent biocompatibility and corrosion resistance performances is coated on the U-shaped magnesium alloy wire. In order to prevent magnesium alloy staple from degrading and losing effect before the cut of a tissue or an organ is overhauled, the surface coating with excellent biocompatibility and certain corrosion resistance performances is coated on the surface of the U-shaped magnesium alloy wire. The surface coating has the advantages of 1, excellent biocompatibility; 2, certain corrosion resistance performances on the electrolyte of a human body; and 3, higher intensity and rigidity under the premise of enough toughness. The surface coating can be a biological ceramics coating, a pure metal or alloy coating and an anode oxidation coating of magnesium alloy.
Description
Technical field
This utility model relates to a kind of medical disposable material---and anastomat (comprising stiching instrument) belongs to technical field of medical instruments with Absorbale magnesium alloy seam nail.
Background technology
It is that the doctor is in order to replace the traditional-handwork sewing method, the tissue that stitching has been cut or the instrument of organ that kiss (seam) closes device (following general designation anastomat).Adopt the anastomat sew application simple, it is convenient to sew up, and wound is little, and it is tight to coincide, and incisxal edge is smooth regular, compares with the manual suture method, safe and effective, is subjected to the doctor's of Clinical Surgery favor and high praise.
The seam nail of existing anastomat adopts titanium or titanium alloy to make.Titanium and titanium alloy biocompatibility are good, corrosion-resistant, anti-fatigue performance all is better than medical stainless steel, are ideal long-term embedded materials comparatively.
Yet, as seam nail, behind anastomotic healing, on function, lost meaning, that is to say anastomotic healing after, the seam nail just loses the value of existence.But the seam that titanium and titanium alloy are made nail, the decay resistance of Yin Qigao, long-term existence in vivo.Titanium (or titanium alloy) the seam nail that becomes line style, circle (or circular arc) shape to arrange causes the patient that foreign body sensation is arranged, and is very uncomfortable, and, also may hinder medical inspection subsequently.
The utility model content
This utility model provides a kind of basic function that can keep the seam nail at wound healing in the phase, can follow closely with the Absorbale magnesium alloy seam by the anastomat for the human body degraded behind wound healing again.
This utility model adopts following technical scheme:
A kind of anastomat is with Absorbale magnesium alloy seam nail, and comprising: U-shaped body, U-shaped body are the U-shaped Mg alloy wire, and it is good and have a face coat of corrosion resistance to be coated with biocompatibility on the U-shaped Mg alloy wire.
This utility model further adopts following technical measures:
The vary in diameter scope of described U-shaped magnesium alloy silk material is 0.2～0.6mm, and the excursion of tensile strength is 200～500Mpa.
Described face coat is the coating of bio-ceramic coating, simple metal or alloy or the anodic oxide coating of magnesium alloy.
The thickness of described bio-ceramic coating is 5～25 μ.
The thickness of the coating of described simple metal or alloy is 0.5～25 μ.
The thickness of described anodized coating is 5～30 μ.
Compared with prior art, the utlity model has following advantage:
Magnesium is the indispensable component of human body, in the contained various cationes of human body, presses the ordering of content number, and magnesium ion occupies the 4th, and is significant to nerve, muscle, skeleton and cardiac function.Mg supplementation is attached great importance on clinical medicine, so magnesium is fool proof as embedded material.
But magnesium and magnesium alloy chemical character are active, and corrosion resistance is poor, in human electrolyte's environment, and can degraded quickly by corrosiveness.Thereby, can adopt magnesium or magnesium alloy materials, produce absorbable anastomat seam nail.Because the degradation speed of magnesium or magnesium alloy is very fast, and the diameter of seam nail is very little, and (surface area of Cylinder is inversely proportional to the Cylinder radius to the ratio of Cylinder volume is approximate, the Cylinder radius is more little, and this ratio is big more, and corrosion rate is also just fast more), thereby degradation speed is faster.Be to prolong degradation time, guarantee the wound healing of tissue or organ firmly before, the seam nail still keeps its due function, makes the layer of surface coating again on magnesium alloy seam nail surface.The characteristic of face coat: one, good biocompatibility.Two, the etching characteristic that has certain anti-human electrolyte, guarantee that wound healing firmly before, magnesium alloy seam nail can keep it to sew up function; In the wound healing process or after the healing firmly, be accompanied by the degraded of magnesium alloy seam nail, also can progressively degrade or fragmentation.Three, under having enough toughness (guaranteeing that when occuring bending and deformation, face coat cracking does not take place and comes off in the seam nail sewing process) prerequisite, also should have high intensity and hardness as much as possible.The good face coat of biocompatibility should have certain corrosion resistance, just can guarantee the seam nail before degraded was lost efficacy, anastomotic stoma can heal, and in the anastomotic healing process or after the healing firmly, be degraded at leisure again or fragmentation, or and then absorbed by human body; The bounce-back that the high strength of face coat and hardness help stitching the stitching of nail and suppresses to sew up the back tissue.

The specific embodiment
Embodiment one: a kind of anastomat is followed closely with the Absorbale magnesium alloy seam, and comprising: U-shaped body 1, U-shaped body 1 is the U-shaped Mg alloy wire, is covered with the bioceramic layer 2 of corrosion resistance in the external packets of U-shaped Mg alloy wire.The vary in diameter scope of described U-shaped Mg alloy wire is 0.2～0.6mm, and the excursion of tensile strength is 200～500Mpa.The thickness of bio-ceramic coating is 10 μ.
Embodiment two: a kind of anastomat is followed closely with the Absorbale magnesium alloy seam, comprise: U-shaped matrix 1, U-shaped matrix 1 is a Mg alloy wire, be coated with the titanium coating of good, the stronger corrosion resistance of biocompatibility on the surface of U-shaped Mg alloy wire, described titanium coating can be titanium electrodeposited coating or titanium chemical deposit.The diameter of Mg alloy wire is 0.35mm, and the tensile strength of silk material is 350MPa.The thickness of titanium coating is 3 μ.
