Automatic thermostatic electric heating tweezers

Abstract

The invention relates to automatic thermostatic electric heating tweezers, which consist of a thermostatic tweezers body, an operating tweezers handle, a PTC heating device, a heating power supply, a display circuit, a box, a quick joint, a quick joint seat and an insulating lead. The automatic thermostatic electric heating tweezers are characterized in that: the thermostatic tweezers body and the operating tweezers handle are connected to form a whole, the PTC heating device is fixed on the middle part of the tweezers, and the PTC heating device is connected with the heating power supply through a cable and the quick joint. The heating power supply, the display circuit and the quick joint seat are assembled in the box together. The electric heating tweezers synthesize the advantages of the novel PTC heating device, the electronic technology and the structure design of the thermostatic tweezers body and the operating tweezers handle. A constant temperature of about 60 DEG C is provided at the tweezers body part. Therefore, pathologic tissue components are not adhered on the tweezers, and the clinical diagnosis error is reduced. The operating tweezers handle has no hand burning feeling. The tweezers eliminate cross infection among the pathologic tissues, provide obvious reliable effect for qualification of a specimen, are simple and convenient to operate, have the advantages of reducing the working steps and improving the working efficiency, and are particularly suitable to be used in pathologic tissue paraffin embedding.

Description

technical field [0001] The invention relates to a professional electric heating tweezers device for clamping pathological tissues into embedding molds at a constant temperature during the embedding process of medical pathological tissues. Background technique [0002] In the tissue embedding work of medical pathological examination, use heated stainless steel tweezers to place the pathological tissue at the bottom of the stainless steel embedding mold, and then fix it in the solidified paraffin of the embedding box, and then place the pathological tissue fixed in paraffin for embedding. The cassette is separated from the embedding mold. This method has been widely used in clinical diagnosis. The usual method of heating stainless steel tweezers: (1) Use an alcohol lamp to repeatedly heat the head of ordinary stainless steel tweezers. The problem that is likely to occur is: when the temperature is high, it will cause changes in the morphology of pathological cells, which is ...

AI Technical Summary

Problems solved by technology

The problem that is likely to occur is: when the temperature is high, it will cause changes in the morphology of pathological cells, which is not conducive to the subsequent diagnosis and observation of slices.

Although the second method eliminates the defect that the temperature may be high, their common problems are: there is a chance of cross-contamination between specimens; the process of heating the tweezers increases the waiting time, reduces work efficiency, and increases labor intensity

In addition, when the tweezers are heated for a long time, due to the temperature transfer of the hand-held operation part, there is a problem of hot hands
