the fixing sleeve 5 is held by the fixing sleeve 5 by holding the tubular container 1 from the bottom of the tubular container 1 upwards. The materials of about 200mg are taken out by scissors and put into a tubular container 1.

Embolia the top of grinding stick 2 with rotatory cover 11, handheld rotatory cover 11 will grind stick 2 and insert tubulose container 1 to rotatory rotary sleeve 11 on the grinding stick 2, grind stick 2 along the insection entering tubulose container 1 in, grind 2 most advanced extrusion of stick and get into the pathological material at the 1 pointed end of tubulose container, play the effect of crushing, the pathological material that extrudees out simultaneously gets into in the thread pool, grind 2 bellied insections of stick and tubulose container 1 internal tooth line and mutually engage, the friction makes the pathological material tissue grind rapidly. The lung tissue and organ tissue that are most difficult to grind by repeatedly rotating the grinding bar 2 can also be easily ground. Taking out or rotating the grinding rod 2 to ensure that the grinding rod 2 and the tubular container 1 have a proper gap, centrifuging instantaneously, centrifuging the ground pathological tissue to the bottom of the tubular container 1, and directly carrying out the next research or directly freezing for standby. Use shows that this practical pathological material grinder mills and smashes a sample and just can accomplish for 5 minutes.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
