Description
Technical field:
The utility model relates to technical field of medical instruments, particularly a kind of Pathologic specimen paraffin embedding preheating tweezers.
Background technology:
The paraffin embedding of Pathologic specimen is that the piece of organizing that soaks into wax is wrapped in the paraffin.Specific practice is, be ready to carton (logical common paper oneself is converted into carton) earlier, dewaxing is poured in the box again, organize piece to lie in carton bottom with the tweezers gripping of pre-temperature rapidly, tangent plane down, mention carton more gently, lie in the cold water, treat that surperficial paraffin solidifies, take out after 30 minutes, embedding should be a little more than saturating wax temperature with the temperature of wax, guarantees to organize piece and paraffin on every side to combine together fully.Paraffin has its unique advantage as embedding medium.For example, paraffin can cut out wax disk(-sc) as thin as a wafer, can be linked to be the wax band during section, is convenient to make serial section, and operation is easier to, and organizes piece can be embedded in the medium-term and long-term preservation of paraffin.Yet in the practical operation, during paraffin embedding, the tweezers of folder sample are wanted preheating in the time of especially will noting embedding, and the sample tangent plane places embedding frame center down, once puts well and does not move sample position again, treats the embedded block hardening half an hour approximately, takes off embedded block.The pre-thermal recovery temperature-constant bucket of traditional tweezers splendid attire tweezers make tweezers keep suitable temperature, but in operating process, the temperature of tweezers constantly descends, and especially, tweezers are stainless steel products, radiating rate is very fast, and in the short 1-2 minute operating process, the temperature of tweezers is undesirable.So, when placing specimen embedding, need rapid gripping organize the bottom that certainly places carton, still, organize the placement of piece require into tangent plane down, and can not the shift position, sometimes owing to avoid the tweezers cooling too fast and hurry operation causes repeatedly slipping up.For solving this technical matters, need appearance a kind of simple in structure, easy to use, gripping organizes the tweezers of piece can be in a kind of Pathologic specimen paraffin embedding preheating tweezers of temperature constant state.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, provides a kind of simple in structure, easy to use, and gripping organizes the tweezers of piece can be in a kind of Pathologic specimen paraffin embedding preheating tweezers of temperature constant state.
To achieve these goals, the utility model provides a kind of Pathologic specimen paraffin embedding preheating tweezers, comprise handle and two elastic arms, two elastic arms constitute V font structure, fixedly connected between two elastic arms and the handle, wherein, the inner hollow of described handle and described elastic arm is provided with lead in it; The end of two elastic arms is provided with electronic thermo-head, the junction of described elastic arm and described handle is provided with temperature detect switch (TDS), the end of described handle is provided with power lead, be electrically connected between described power lead, described lead, described electronic thermo-head and the described temperature detect switch (TDS), plug together between described electronic thermo-head and the described elastic arm and fixedly connected.
An elastic arm is provided with the thumb collar, another elastic arm is provided with the forefinger collar and middle finger sleeve ring, the inboard of the end of two elastic arms is provided with anti-skidding tweezer head, described anti-skidding tweezer head is provided with some textures, and the described thumb collar, the described forefinger collar, described middle finger sleeve ring, described anti-skidding tweezer head and described elastic arm are one-body molded during fabrication.
Fixedly connected between described temperature detect switch (TDS) and the described handle.
Described power lead is used for connecting external power source.
Described texture and described anti-skidding tweezer head are one-body molded during fabrication
Advantage of the present utility model is that simple in structure, easy to use, gripping organizes the tweezers of piece can be in temperature constant state, is specially:
The utility model changes handle and the elastic arm (being the integral body of traditional tweezers) of traditional tweezers into cavity structure, interspersed lead (being electric wire) in it, the tweezers end plugs together the connection electronic thermo-head, and fixed installation place of handle and elastic arm arranges temp. controlling box, by temp. controlling box control electronic thermo-head temperature constant state.For further facilitating operation, the thumb collar, the forefinger collar and middle finger sleeve ring are set prevent the hand slippage, by the tweezer head texture is set and prevents from organizing the piece slippage.
