Technical Field

The utility model relates to a sword technical field of drawing materials specifically is a medical pathologic sampling sword of improvement.

Background

In the operation procedure of pathological material taking, the method for taking materials and the use of a material taking knife are strictly guided. For example, the formalin fixation speed is generally 1mm/h, and in order to ensure sufficient fixation of the tissue in the formalin, the thickness of the removed tissue block should not exceed 4mm, and the thickness of the tissue containing fat or high-density fibers should not exceed 3 mm. Pathologists often draw materials by hand feeling, young doctors with the materials are difficult to master the thickness, and the thickness of tissue blocks is possibly uneven, so that diagnosis is influenced. The prior pathological sampling knife can not fix the thickness of the cut tissue and can possibly influence the quality of sampling. In view of this, we propose an improved medical pathologic sampling knife.
