Description
Technical field
The present invention relates to clamping device technical field, more particularly to a kind of medical antibacterial easy-to-replace head tweezers.
Background technology
Tweezers are a kind of conventional aids, because it can accurately and easily grip object, and are widely used in doctor
The industries such as, beauty, electronics.
Existing tweezers include tweezers head and corresponding fixing end, and after being used for a long time, tweezers head is most fragile, most
The first denier of tweezers easy to wear is damaged, and whole tweezers are to scrap, and waste material；Further, since the product to be clamped and
The difference of its own specification, it is necessary to prepare the tweezers of different size, which in turns increases cost.As to above-mentioned technical problem
Improvement, in the market provide a kind of tweezers of replaceable tweezers head, fix, compare however, this tweezers usually require screw
It is cumbersome, change inconvenient.In addition, tweezers anti-microbial property of the prior art is poor, be not suitable for long-term medical.
Chinese patent patent of invention, application publication number：CN102476359A discloses a kind of tweezers, including the elasticity of tool two
The body of tweezer handle and two tweezers heads, each tweezers head open up an accommodating cavity, and two tweezer handle can be respectively clamped into the appearance of the two tweezers head
Put chamber.The tweezer handle of the tweezers can be caught in the accommodating cavity of tweezers head, conveniently replaced tweezers head, but be located on the body of tweezer handle and be used for
The shell fragment of clamping tweezers head, it is after a number of uses, also fragile, once damaging, also lead to whole tweezers and scrap, waste
Material.
It is badly in need of a kind of medical antibacterial easy-to-replace head and the longer forceps of service life in the industry.
The content of the invention
Present invention aims at a kind of medical antibacterial easy-to-replace head tweezers are provided, damaged with solving the first denier of tweezers most easy to wear
Bad, whole tweezers are to scrap, the technical problem of waste of materials and tweezers anti-microbial property difference.
To achieve the above object, the present invention provides a kind of medical antibacterial easy-to-replace head tweezers, its easy-to-replace head, the antibacterial that can light and
Service life is longer, and the technical scheme used is as follows：A kind of medical antibacterial easy-to-replace head tweezers, including two elastic forceps handles and two tweezers
Subheader, one end of two elastic forceps handle is fixed together, the spaced formation free end of the other end, and two elastic forceps handle is free
Accommodating cavity, which is respectively arranged with, on the relevant position of end is respectively equipped with a neck for connecting accommodating cavity, described two with and in symmetrical two sides
Elastic forceps handle outer surface be respectively coated luminous paint layer, the luminous paint in fluorescent paint or phosphorescent paint one
Kind, the two tweezers head includes tweezers head front portion and tweezers back of head, and the tweezers back of head is installed with two elastic arms,
Two elastic arm is symmetrically installed on the both sides of the tweezers back of head, the two elastic arms width and tweezers back of head section
Width is identical, and two free end of elastic arm are respectively equipped with corresponding with the neck raised.The tweezers head is removably mounted on
In the tweezer handle.
Two elastic forceps handle is made by the raw material of following parts by weight：It is 80-90 parts of polypropylene, 10-15 parts of antibacterial filler, anti-
1-2 parts of oxygen agent；
Wherein, the antibacterial filler is prepared by following steps：
1) synthesis of polypyrrole nanotube：By FeCl3•6H2O, methyl orange are dispersed in water, when having waited flocculent substance generation, plus
Enter pyrrole monomer, be stirred at room temperature 24-30 hours.The suspension of black is obtained, filtering drying obtains the solid matter of black；
2）Dihalo compound modifies polypyrrole nanotube：Will be through step 1）The polypyrrole nanotube prepared, ultrasonic disperse in
In DMF, dihalo compound is then added dropwise, stirring reaction 4-8 hours at 40-60 DEG C.The isolated black solid of suction filtration, according to
It is secondary to be washed 3-5 times respectively with ethyl acetate, ether, then it is dried in vacuo 12-24 hours at 40-50 DEG C, obtains product；
3）Dopamine grafting dihalo compound modification polypyrrole nanotube：Will be through step 2）The dihalo compound modification prepared
Polypyrrole nanotube be dispersed in the aqueous solution of 1-2mol/L dopamine at 40-50 DEG C keep 60-72 hours, then in water
Middle immersion 30-48 hours, filtering is dried in vacuo 12-24 hours at 40-50 DEG C, obtains product；
4）The preparation of antibacterial filler：Will be through step 2）The polypyrrole of dihalo compound modification after the dopamine grafting prepared
Nanotube, which is dispersed in the aqueous solution of 1-2mol/L sodium alginate at 40-50 DEG C, to be kept for 60-72 hours, is then soaked in water
30-48 hours, filtering was dried in vacuo 12-24 hours at 40-50 DEG C, obtains product；
Further, step 1）Described in FeCl3•6H2O, methyl orange, water, the mass ratio of pyrrole monomer are：50：2：（250-
500）：（2-4）；
Further, step 2）Described in polypyrrole nanotube, DMF, the mass ratio of dihalo compound be：1：（5-8）：（5-
10）；
The dihalo compound is selected from 1.2- dichloropropanes, 1,4- dichloroetane, 1,5- dichloropentane, pentamethylene bromide, 1,
One or more in 4- dibromobutanes, the chlorobromopropanes of 1.2- bis-；
The antioxidant in antioxidant 1010, antioxidant 168, antioxidant 1024, antioxidant 1076 one
Plant or several；
Because above-mentioned technical proposal is used, the present invention has following advantages compared with prior art：It is disclosed by the invention medical anti-
Bacterium easy-to-replace head tweezers occur that tweezers head fractures, rust etc. causes in tweezers using elastic forceps handle and the split type snap fit of tweezer head
During its non-serviceable situation, tweezers head can be taken out, and change new tweezers head, so as to make full use of handle indefectible
Feature, extends the service life of tweezers to greatest extent, so as to save material, reduction use cost, it also avoid tweezers and leads to
Often screw is needed to fix, comparatively laborious, the problem of changing inconvenient；In addition, tweezers elastic forceps handle is prepared into using anti-biotic material
Arrive, with antibiotic effect, polypyrrole pipe surface product is big, advantageously ensures that antibiotic property, antistatic behaviour, and synthetic material are can guarantee that again
On be grafted with the groups such as dopamine, alginic acid so that the biocompatibility that this tweezers has had, in tweezers elastic forceps handle outer surface
Luminous paint layer is coated with, can light, be easily found in the dark, light filling is played when being also suitable in the dark using tweezers, will not
Produce shade.
