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 the anastomosis staple that a kind of medical coinciding machine is used, be specifically related to a kind of biodegradable and contain silver coating pure iron anastomosis staple and preparation thereof.
Background technology
Along with the development of medical science technology, the doctor carries out tissue or organ is sewed up, and from original mode with the needlework manual suture, changes the mode of sewing up with medical anastomat and alloy anastomosis staple into.Use medical anastomat to sew up, convenient operation, the wound of coincide safely, bringing is very little, is accepted by vast surgical clinical doctor.But existing medical anastomat anastomosis staple used mostly adopts titanium alloy to make, because the titanium alloy corrosion resistance is relatively high, after sewing up, the titanium alloy anastomosis staple can be stayed in tissue or organ for a long time, might cause inflammation, not very comfortable sensation is always arranged for the people.So the scientific and technical personnel of medical science and biomaterial circle are according to the tissue characteristics of some metal materials, in succession develop the magnesium alloy materials that absorbs with degradable and make anastomosis staple, substitute the titanium alloy anastomosis staple to carry out the stitching of human tissue organ, allow be degraded when staying magnesium alloy anastomosis staple in human tissue organ along with the slowly healing of wound after sewing up or fragmentation is fallen.
But, reason due to magnesium alloy composition in the anastomosis staple of degradable absorption magnesium alloy materials, also there are some corresponding adverse effects, such as: the human tissue organ position of stitching directly contacts the anastomosis staple material, due to mishandling factor in the process of coincideing, be easy to cause wound infection and form secondary insult, give clinical verification and come into operation and cause some obstacles.
Summary of the invention
the purpose of this invention is to provide a kind of simple in structure, easy to use, be very suitable for the identical medical bio degradable of human tissue organ and contain silver coating pure iron anastomosis staple, it is by pure iron and Zn, Ca, the alloy material that Mn forms, mode by the extrusion process shaft that arches upward in pure iron anastomosis staple middle part that is shaped, vertical nail body and nail tip, make the pure iron anastomosis staple, surface uniform coating layer of copper ionic coating due to the pure iron anastomosis staple, can play the anti-inflammation and sterilization effect to the identical wound surface of section of human tissue organ, the pure iron anastomosis staple is along with the healing of the wound degraded that can be absorbed by the body, the problems referred to above that existing anastomosis staple exists have effectively been solved.
The invention provides a kind of biodegradable and contain silver coating pure iron anastomosis staple, a kind of biodegradable contains silver coating pure iron anastomosis staple, it is characterized in that, the material composition of described pure iron anastomosis staple and proportioning be, pure iron 99.98～99.99%, Zn0.008～0.008%, Ca0.003～0.006%, Mn0.003～0.006%.
A kind of biodegradable provided by the invention contains silver coating pure iron anastomosis staple, and described pure iron anastomosis staple comprises the anastomosis staple shaft that arches upward at a middle part, and anastomosis staple shaft two ends are vertical nail body through round-corner transition, and the front end of nail body is nail tip.
Biodegradable of the present invention contains 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 contains 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 1:
The material that is pure iron 99.98～99.99%, Zn0.004～0.008%, Ca0.003～0.006%, Mn0.003～0.006% with composition and proportioning 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;
