Description

Pathological specimen cutter for clinical pathological diagnosis

Technical Field

The utility model relates to the technical field of clinical specimen processing instruments, in particular to a pathological specimen cutting knife for clinical pathological diagnosis.

Background

The pathological diagnosis is a disease diagnosis by observing the gross changes of organs and observing the characteristics of tissue structures and cytopathic conditions under the microscope, and therefore, it is more objective and accurate than the clinical analytic diagnosis based on the medical history, symptoms and signs, and the diagnosis made by using various images (such as ultrasonic waves, X-rays, CT, nuclear magnetic resonance, etc.). Although modern diagnostic methods of molecular biology (such as PCR, in situ hybridization, etc.) have been increasingly applied to medical diagnosis, pathological diagnosis is still considered as diagnosis with declared properties. Since pathological diagnosis is often performed by biopsy or autopsy, it is necessary to answer questions such as the exact diagnosis and the cause of death that the clinician cannot make. However, pathological diagnosis is not absolutely correct, much less universal, and has inherent subjective and objective limitations as well as other disciplines. Therefore, the improvement of the technical level of the patient and the mutual communication between clinic doctors and pathologists are necessary to reduce and avoid missed diagnosis and misdiagnosis. Modern pathology takes up recent research and results in molecular biology today, allowing observation of pathology from the organ, cellular level, to subcellular, protein expression and genetic changes. This not only makes the pathological study more intensive, but also makes the pathological study methods penetrate into various basic disciplines, clinical medicine, preventive medicine, pharmacy, etc. If the change of a certain gene is accompanied by the abnormality of protein expression and protein function, the morphological change can occur; conversely, whether a morphological abnormality is an abnormality or a change in expression of a certain gene. In clinical medicine, the identification and explanation of some symptoms and signs, the discovery and prevention of new disease species, the screening of sensitive drugs, the development of new drugs, toxic and side effects and the like can not be separated from the identification and explanation of the pathology.
