Abstract
The invention provides a biodegradable pure iron anastomosis nail containing a silver coating. The material components and proportions of the pure iron anastomosis nail comprise 99.98% to 99.99% of pure iron, 0.004% to 0.008% of Zn, 0.003% to 0.006% of Ca, and 0.003% to 0.006% of Mn. The pure iron anastomosis nail comprises an anastomosis nail rod body which hunches up from the middle portion, two ends of the anastomosis nail rod body transfer to form vertical nail bodies through fillets, and a nail point is arranged at the front end of each nail body. Due to the facts that the rod body hunches up from the middle portion, the front ends are provided with the nail points, and the vertical nail bodies transfer through the fillets, the anastomosis nail is suitable for an anastomat which is used for anastomosis of human tissue and organs, the nail bodies of the anastomosis nail are pressed to the middle through a pressing rod of the anastomat in the process of anastomosis, the human tissue and organs are sutured together, the function of anti-inflammatory and sterilization to anastomosis wound surface of the human tissue and organs is achieved through a layer of cupric ion coating which is evenly coated on the surface of the pure iron anastomosis nail, the human tissue and organs utilizing the pure iron anastomosis nail for the anastomosis are free from infection, the anastomosis nail is absorbed and degraded with union of the wound, and the anastomosis nail is beneficial for shortening of time of union and recovery of the wound surface.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of anastomosis staple of medical coinciding machine, be specifically related to a kind of biodegradable containing silver coating pure iron anastomosis staple and preparation thereof.
Background technology
Along with the development of medical science technology, doctor carries out tissue or organ and sews up, and from original mode with needlework manual suture, has changed into and carries out with medical anastomat and alloy anastomosis staple the mode sewed up.Use medical anastomat to sew up, convenient operation, the wound coincide safely, brought is very little, by vast surgical clinical doctor is accepted.But existing medical anastomat anastomosis staple used mostly adopts titanium alloy to make, because titanium alloy corrosion resistance is relatively high, after sewing up, titanium alloy anastomosis staple can be stayed in tissue or organ for a long time, likely causes inflammation, always has not very comfortable sensation to people.So the scientific and technical personnel of medical science and biomaterial circle are according to the tissue characteristics of some metal materials, the magnesium alloy materials in succession developed with degradable absorbs manufactures anastomosis staple, substitute the stitching that titanium alloy anastomosis staple carries out human tissue organ, allow to be degraded when to stay the slowly healing of the magnesium alloy anastomosis staple in human tissue organ along with wound after sewing up or fragmentation is fallen.
But, because degradable absorbs the reason of magnesium alloy composition in the anastomosis staple of magnesium alloy materials, also there are some corresponding adverse effects, such as: the human tissue organ position of stitching directly contacts anastomosis staple material, due to factor mishandling in the process of coincideing, be easy to cause wound infection and form secondary insult, to clinical verification with come into operation and cause some obstacles.
Summary of the invention
The object of this invention is to provide a kind of structure simple, easy to use, be very suitable for the identical medical bio degradable of human tissue organ containing silver coating pure iron anastomosis staple, it is by pure iron and Zn, Ca, the alloy material of Mn composition, to be shaped the shaft arched upward in the middle part of pure iron anastomosis staple by the mode of extrusion process, vertical nail body and nail tip, make pure iron anastomosis staple, due to surface uniform coating one deck copper ion coating of pure iron anastomosis staple, the anti-inflammation and sterilization effect of wound surface that portion of human tissue organ coincide can be played, pure iron anastomosis staple to be absorbed by the body degraded along with the healing of wound, effectively solve the problems referred to above that existing anastomosis staple exists.
The invention provides a kind of biodegradable containing silver coating pure iron anastomosis staple, described pure iron anastomosis staple comprises the anastomosis staple shaft arched upward at a middle part, and anastomosis staple shaft two ends are vertical nail body through fillet (3) transition, and the front end of nail body is nail tip;
Material composition and the proportioning of described pure iron anastomosis staple be, pure iron 99.98 ~ 99.99%, ZnZn0.004 ~ 0.008%%, Ca0.003 ~ 0.006%, Mn0.003 ~ 0.006%.
Biodegradable of the present invention, containing silver coating pure iron anastomosis staple, is further characterized in that, the surface uniform of described pure iron anastomosis staple is coated with one deck silver and is coated with ionic coating, and the thickness of coating is: 0.005 ~ 0.01mm.
Biodegradable of the present invention is containing the preparation method of the pure magnesium anastomosis staple of silver coating, and the preparation method of this pure iron anastomosis staple comprises the following steps:
Step one:
With composition and proportioning be pure iron 99.98 ~ 99.99%, the material of Zn0.004 ~ 0.008%, Ca0.003 ~ 0.006%, Mn0.003 ~ 0.006% pulls into the wire rod of 1mm × 1mm;
Step 2:
In pure iron wire surface coating silver ion coating, the thickness of coating is: 0.005 ~ 0.01mm;
Step 3:
By becoming material section under the entire length of single pure iron anastomosis staple;
Step 4:
With bending extruder so that pure iron anastomosis staple material section extrusion molding is gone out the anastomosis staple shaft arched upward in the middle part of pure iron anastomosis staple, vertical nail body and nail tip.
Biodegradable of the present invention is containing silver coating pure iron anastomosis staple, the alloy material be made up of pure iron and Zn, Ca, Mn pulls into wire rod, the mode of extrusion process is adopted to be shaped the shaft, vertical nail body and the nail tip that arch upward in the middle part of pure iron anastomosis staple, make pure iron anastomosis staple, the shaft arched upward due to the middle part containing silver coating pure iron anastomosis staple and front end are that the vertical nail body of nail tip is through round-corner transition, it is applicable to anastomat and coincide for human tissue organ very much. when coincideing, by the depression bar of anastomat, the nail body of anastomosis staple can be pressed to centre, human tissue organ is stitched together.By one deck copper ion coating of pure iron anastomosis staple surface uniform coating, anti-inflammation and sterilization effect is played to human tissue organ's wound surface that coincide, make with harmless and with the addition of the material of some other trace pure iron anastomosis staple coincide human tissue organ not infected, and to be absorbed by the body degraded along with the healing of wound, be more conducive to shortening the healing of wound surface and the time of rehabilitation.
