Cell puncture needle for pathological examination

Abstract

The invention provides a cell puncture needle for pathological examination, and relates to the technical field of medical instruments. The cell puncture needle for pathological examination comprises aneedle cylinder and a fixing frame, a needle core is arranged in the needle cylinder, the rear end of the needle core penetrates through a second sealing block to extend outwards and is fixedly connected to a first handle, the needle core is in sliding connection with the second sealing block, the rear end of a movable rubber block is fixedly connected to a movable rod, and the rear end of the movable rod penetrates through an exhaust hole to extend outwards and is fixedly connected to a second handle. The front end of the puncture needle is kept in a closed state, other cell tissues of a human body can be prevented from entering the needle core to influence an examination result, an obtained cell tissue sample at the lesion position is prevented from polluting other normal cell tissues of the human body, foreign matters in the air are prevented from polluting the obtained cell tissue sample, the fixing frame reduces the operation difficulty of doctors and greatly relieves the pain ofpatients, and the cell puncture needle is worthy of being widely popularized.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a cell puncture needle for pathological examination. Background technique [0002] Pathological examination is a pathological method used to examine pathological changes in organs, tissues or cells of the body. In order to explore the disease process of organs, tissues or cells, a certain method of pathological examination can be used to check them The lesions occurred, discuss the cause of lesions, pathogenesis, the process of occurrence and development of lesions, and finally make a pathological diagnosis. The inspection method of pathomorphology first observes the pathological changes of the gross specimen, and then cuts out a certain size of lesions. Pathological sections were made by histopathological method, and the lesions were further examined with a microscope. [0003] Puncture needles need to be used practically during pathological examinations, and puncture...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a cell puncture needle for pathological examination, which solves the problem of impure puncture sampling caused by the opening at the front end of the puncture needle, or the problem that the cell tissue sample is polluted in the air after sampling, and the problem of sampling When the diseased cell tissue sample may contaminate the normal cell tissue of the human body, it can also reduce the difficulty of the doctor's operation when performing puncture sampling and reduce the patient's pain
