As shown in fig. 1 to 3, the present utility model provides a polishing rod 100, wherein the polishing rod 100 can be placed in a polishing tube 300 containing a biological tissue sample 400, and the polishing rod 100 can be driven by an external power mechanism 200 to reciprocate up and down so as to polish the biological tissue sample 400, thereby obtaining DNA and RNA in the biological tissue sample 400.
As shown in fig. 1, the polishing rod 100 includes a butt 110, a connection rod 120, and a polishing head 130, which are sequentially connected. The docking head 110 can be docked with the power mechanism 200, and the power mechanism 200 can drive the grinding rod 100 to reciprocate by the docking head 110. In some embodiments, the power mechanism 200 is capable of powering the movement of the grinding rod 100 in the direction of its central axis after the connection of the docking head 110 to the grinding rod 100. By pressing the biological tissue sample 400 by the reciprocating movement of the polishing rod 100, the cells in the biological tissue sample 400 can be sufficiently ruptured, and DNA and RNA can be sufficiently extracted. Compared with the prior art that the biological tissue sample is polished by utilizing the collision of a plurality of polishing balls in the biological tissue sample, the polishing rod 100 is high in efficiency, the polishing rod 100 is easy to be taken and placed from the polishing tube 300, and pollution to the biological tissue sample 400 can be avoided.
In addition, abrasion occurs in the collision process of the grinding balls in the prior art, and substances falling off in the abrasion process can pollute biological tissue samples; and a large amount of bubbles can be generated in the grinding tube in the grinding process, so that the subsequent culture and extraction of the biological tissue sample can be inconvenient.
With continued reference to fig. 1, the connecting rod 120 is used to connect the abutment 110 and the grinding bit 130, and the connecting rod 120 has two ends, one of which is connected to the abutment 110 and the other of which is connected to the grinding bit 130. It should be noted that, in some embodiments, the polishing rod 100 is an integrally formed structure, that is, the polishing rod 100 is formed by cutting or other processes on a bar material to form the abutment 110, the connecting rod 120, and the polishing head 130; in some other embodiments, the polishing rod 100 is a combined structure, i.e. the abutment 110, the connecting rod 120 and the polishing head 130 are manufactured separately, and then the abutment 110, the connecting rod 120 and the polishing head 130 are assembled by a specific connection method, including but not limited to welding, magnetic connection, clamping connection and connecting piece connection.

In some embodiments, the polishing head 130 has a tapered structure, and the tapered structure has a small friction when contacting the biological tissue sample 400, so that the tissue liquid formed by polishing is not easy to wall. In some embodiments, with continued reference to fig. 1, the polishing head 130 is spindle-shaped, and in particular, the polishing head 130 includes a first tapered portion 131 and a second tapered portion 132, a large-sized end of the first tapered portion 131 is connected to a large-sized end of the second tapered portion 132, a small-sized end of the first tapered portion 131 is connected to the other end of the connecting rod 120, and a small-sized end of the second tapered portion 132 is used for polishing the biological tissue sample 400. The spindle-shaped polishing head 130 not only has a large contact area when in contact with the biological tissue sample 400, thereby enabling a better polishing effect, but also can prevent the polished biological tissue sample 400 from running out along the side wall, resulting in ineffective polishing.
Further, the grinding end of the grinding bit 130 has a circular arc grinding face 1321, and in some embodiments, the circular arc grinding face 1321 is disposed at the small-sized end of the second tapered portion 132. The circular arc shaped grinding surface has good grinding effect on the biological tissue sample 400. In some embodiments, the abrasive surface is hemispherical.

Specifically, the connecting rod 120 includes a first rod portion 121 and a second rod portion 123 that are connected to each other, the first rod portion 121 has a larger size than the second rod portion 123, one end of the first rod portion 121 away from the second rod portion 123 is connected to the abutment 110, and one end of the second rod portion 123 away from the first rod portion 121 is connected to the grinding bit 130. The stepped surface between the second shaft 123 and the first shaft 121, the cylindrical surface of the second shaft 123, and the conical surface of the second conical portion 132 form the above-described solution tank structure 140.
In some embodiments, the connecting rod 120 further includes a tapered rod portion 122, the large-sized end of the tapered rod portion 122 is connected to the first rod portion 121, and the small-sized end of the tapered rod portion 122 is connected to the second rod portion 123. In some more specific embodiments, the first rod portion 121 and the second rod portion 123 are both cylindrical rods, the first rod portion 121 has a size equal to the large-sized end of the tapered rod portion 122, the second rod portion 123 has a size smaller than the small-sized end of the tapered rod portion 122, and the second rod portion 123 has a size equal to the small-sized end of the second tapered portion 132.
As shown in fig. 2 and 3, the polishing rod 100 can be connected to the power mechanism 200 by plugging. Specifically, the power mechanism 200 is provided with a plug block, the butt joint 110 of the grinding rod 100 is provided with a plug hole 111, and the plug block can be inserted into the plug hole 111 so as to realize detachable connection of the grinding rod 100 and the power mechanism 200. Of course, in some embodiments, the positions of the plug and the plug hole 111 may be interchanged, i.e., the plug is disposed on the abutment 110 of the grinding rod 100, and the plug hole 111 is disposed on the power mechanism 200. Of course, instead of using a plug connection, the grinding rod 100 and the power mechanism 200 may be detachably connected by a clamping connection, a threaded connection, a magnetic connection, or an expansion connection, where the expansion connection is similar to the connection of an expansion bolt.
