Histotome device for pathologist

Technical Field

The utility model belongs to the technical field of pathology chemical examination appurtenance, concretely relates to pathology doctor is with tissue slice device.

Background

The different types of operations make the specimens which are correspondingly cut out different. For some neoplastic specimens, failure to completely remove the tumor and its relationship to the surrounding area will have a major impact on subsequent pathological diagnosis and post-operative treatment of the patient. Because the relationship between the two is not clarified, the infiltration relationship between the tumor and the periphery cannot be determined, whether the tumor is infiltrated or not, whether the tumor is a vascular tumor embolism or nerve invasion is determined; or due to the friction of the front and back reciprocating knife in the process of material taking and cutting, the cut tissue is cracked or separated, and the tumor is polluted; or the excised tumor tissue blocks are not uniform and incomplete, so that the tissue is obliquely cut later (the tissue slices are only 3-4 microns thick, so that the tissue is easy to overlap during slicing, or the tumor drifts or floats on the slices during the slice spreading process). The pathological doctors can not accurately define the cause of the tumor under all the conditions, namely, the pathological doctors can not clearly distinguish whether the tumor invades the vascular nervous tissue, or the tumor exists around the tumor, or the pathological doctors are caused by human factors.

Therefore, it is very important to provide a slicing device capable of preventing the tissue mass from being contaminated by the tumor and ensuring the thickness of the tissue, the integrity of the tissue mass and the relation with the surrounding tissues.
