Tissue fixing device applied to pathological tissue paraffin embedding box

The utility model discloses a tissue fixing device applied to a pathological tissue paraffin embedding box. The device disclosed by the utility model is applied to an embedding box with a common specification, is in a square frame shape, and can fix strip-shaped and sheet-shaped tissues on one side in the embedding box, and the drawer clamping groove of the fixing device and the part vertical to the front end of the bracket of the fixing device can form a clamping and locking structure, so that the aim of limiting the movement and deformation of the tissues is fulfilled; the width of the fixing device can be adjusted according to the thickness of tissues, and gears can be freely adjusted. The device is made of an organic solvent-resistant and temperature-resistant material, can be cleaned and disinfected, and can be repeatedly used. The part in contact with the tissue is covered with a flexible material, so that the tissue cannot be physically extruded, and pores are formed, so that liquid permeation is facil
