Description of drawings

Fig. 1 is that the structure of this utility model nanometer silver silk thread is formed sketch map.

The specific embodiment

Referring to Fig. 1, this utility model is a kind of nanometer silver silk thread, and by forming as the operation suture thread 1 of base material with at the simple substance silvering 2 of outer side covers all around of this operation suture thread 1, the diameter of this nanometer silver silk thread is between 0.5～1.0 millimeter.Wherein the silver in the simple substance silvering is the nanometer state, and silver-colored particulate diameter is not more than 25 nanometers, and the thickness radius of silvering is to be equal to or greater than 0.01 millimeter.Wherein operation suture thread is a medical catgut, or collagen protein line or bioprotein line or chitin fiber, other medical fibre that maybe can be absorbed by the body.

Construction features of the present utility model is to cover the simple substance silvering of one deck nanometer state around the outside of medical operation suture thread, so that make full use of sterilization and promotion tissue repair and regenerated medical functions that simple substance silver self is had.It is the precision instrument that adopts the high-tech nanotechnology, simple substance silver is carried out resolution process, the impurity that separates and exclude in the silver to be comprised, will carry over again be the nanometer state and absorbable fine silver simple substance granule is made around being plated on the outside of medical operation suture thread.So, which medical functions does silver have actually? this utility model is compared religion with common medical catgut, have which feature performance benefit?

According to putting down in writing in the Ancient Chinese Compendium of Material Medica in generation: give birth to silver, flavor raw meat, cold, nontoxic.The silver bits, settling five organs, the centering rule, spasmolytic is throbbed with fear, and removes pathogen, and clothes are made light of one's life by commiting suicide all the year round for a long time.Li Shizhen (1518-1593 A.D.) is said: " this is nontoxic for silver, its poison then clear thing poison also." therefore, the ancestors of the Chinese nation learn and utilized silver-colored medical function and value for a long time.The report that the lethal effect that abroad silver is had kill bacteria, silver might become a kind of disinfectant also is the nineties as far back as 19th-century, surplus modern existing 200 year.And, the chemical compound that widely used always so far clinically silver sulfadiazine is exactly a kind of silver, silver sulfadiazine is that silver and antibiotic are combined as a whole, formation has the medicine of efficient sterilizing effect to fungus and antibacterial.This medicine can use 30g (argentiferous 9.06g) at most every day, does not find that so far significantly poison is paid effect.When human body was subjected to chronic injury, the metal proteinase activity in the wound can strengthen.The medical mechanism of silver sulfadiazine is: silver can reduce too much MMP activities, promotes tissue repair and regeneration.The chemical compound that also has a kind of silver---being used to burn and the silver nitrate of trauma care, also is a kind of conventional medicine.10～20% silver nitrate can be used for treating cervical erosion.

When using this utility model to carry out catgut embedding for treatment, be this utility model to be truncated to the line segment that length is about about 1.5 centimetres imbed human acupoint, except the acupuncture point being produced long lasting conventional physical stimulation, can also utilize the following three phases effect of silver, produce the effect of antibiotic, infection and promotion wound healing:

At first be to exist antibacterial or fungus generation chemical action in highly active silver-colored granule and the wound, play sterilization, anti-infectious function, this process just makes in 20-30 minute that usually antibacterial or fungus have lost vigor.

Then, silver acts on into the cell of fiber, makes it turn back to embryonism, becomes stem cell, and these cells are general life members, and effect is to set up new human body again.

At last, living cells in silver granule and the wound area forms compound, produces the stem cell that can deliver at once, and a large amount of stem cell are filled wound, will change the normal class histiocyte before new, the damage rapidly into, final transformation result is that all anatomical structures are repaired fully.
