As an improvement, the pincers are hinged upper there are one fixed link, the end of the fixed link is equipped with protrusion, and described is another Equipped with rack, protrusion is stuck in rack one pincers.
As an improvement, the articulated shaft of the fixed link and pincers handle is equipped with the spring that limitation fixed link rotates counterclockwise.
As an improvement, the binding clip is equipped with polymer antimicrobial coating.
As an improvement, the thickness of polymer antimicrobial coating is 10-100 μm.
As an improvement, the polymer antimicrobial coating is a kind of makrolon multi-monomer grafting polymer, described connects Branch monomer is included containing phenyl ring or pyridine ring unsaturated silane and acrylonitrile monemer.
As an improvement, the unsaturated silane monomer is selected from：Triple phenoxyl vinyl silanes, 3- chloropropyl dimethyl second Alkenyl silanes, triphenyl vinyl silane, 3,5-dimethylphenyl vinyl silanes, dimethyl (2- pyridyl groups) vinyl silanes.
As an improvement, the polymer and grafted monomers parts by weight of raw materials is as follows：100 parts of makrolon, unsaturated silicon 5-20 parts of alkane monomer, 5-20 parts of acrylonitrile monemer.
As an improvement, the preparation method of the polymer coating is as follows：
Step A：Unsaturated silane, acrylonitrile are uniformly mixed；
Step B:Makrolon is melted in rheometer；
Step C：Mixture and initiator after step A are added in rheometer, react 5 min -10min..
As an improvement, the initiator is selected from benzoyl peroxide, lauroyl peroxide, isopropyl benzene hydroperoxide, uncle Butylhydroperoxide, cumyl peroxide.
As an improvement, the initiator is benzoyl peroxide and the mixture of cumyl peroxide, molar ratio is 1:（0.7-1.5）.
As an improvement, the melting time of the step B is 1-5min.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：The present invention can be according to using Situation is bent, versatile, easy to operate.
It is shown in the test for having antimicrobial coating and not having the bronchus forceps of antimicrobial coating to carry out after a period of time, it is novel poly- The pathogen residual quantity of conjunction object coating surface just corresponds to a ten thousandth rank of common bronchus forceps surface bacteria quantity.
