One side of the upper-stage filter disk 3 is rotatably connected to the side wall of the receiving cavity, and the other side is connected to a transmission mechanism.

[0025] Further, a connecting rod 6 is provided on the upper-stage filter disk 3. An activity slot 7 is vertically formed on the cylinder 2. The connecting rod 6 is connected to the transmission mechanism, and the transmission mechanism drives the connecting rod 6 to move up and down in the activity slot 7.

[0026] Further, a support frame 8 is provided on the mounting base 1. A rotating shaft 9 is rotatably provided on the support frame 8. An eccentric wheel 10 is connected to the rotating shaft 9. The rotating shaft 9 is connected to the transmission mechanism.

[0027] Further, the transmission mechanism is a rotary motor.

[0028] Further, the transmission mechanism includes a belt 111, a first pulley 112, a second pulley 113, and a tension pulley 114 disposed on a support frame 8; the first pulley 112 is connected to the rotary shaft 9, the belt 111 is wound around and abuts against the first pulley 112, the second pulley 113, and the tension pulley 114, the second pulley 113 is connected to a rotary motor, the rotary motor drives the second pulley 113 to rotate, and the first pulley 112 and the tension pulley 114 rotate synchronously under the action of the belt 111 to drive the rotary shaft 9 to rotate.

[0030] Further, a plurality of limiting holes 82 are formed in the support frame 8, and the fixed shaft 81 can be connected to any one of the limiting holes 82.

[0031] The working principle of the present utility model is as follows:

[0032] During use, the tissue dispersion liquid to be filtered is first poured onto the primary filtering disc, and then the transmission mechanism is started. Since one side of the primary filtering disc is rotatably connected to the inner wall of the accommodating cavity, and the other side is connected to a connecting rod 6, and the transmission mechanism is connected to a rotary shaft 9, and an eccentric wheel 10 is provided on the rotary shaft 9, the transmission mechanism can drive the rotary shaft 9 to rotate, thereby driving the eccentric wheel 10 to rotate; due to the asymmetry of the eccentric wheel 10, the eccentric wheel 10 approaches or moves away from the connecting rod 6 during rotation, causing the connecting rod 6 to swing, and the connecting rod 6 is provided on the primary filtering disc 3, so the connecting rod 6 will drive the primary filtering disc 3 to swing. At this time, in addition to the tissue dispersion liquid on the primary filtering disc entering the secondary filtering disc 4 through the filter holes 5 under the action of gravity, due to the up and down swing of the primary filtering disc 3, the filtration of larger tissues and impurities such as adipose tissue, membrane tissue, and connective tissue in the tissue dispersion liquid can be accelerated, thereby accelerating the filtration speed; at this time, the tissue dispersion liquid filtered by the primary filter enters the secondary filtering disc 4, and the filter holes 5 of the secondary filtering disc 4 filter out the tumor cell clusters in the tissue dispersion liquid, and the remaining tissue dispersion liquid enters the bottom of the cylinder 2, and later the staff collects the tissue dispersion liquid at the bottom of the cylinder 2. Through the cooperation of structures such as the transmission mechanism, the present application drives the primary filtering disc 3 to form an up and down swinging state, accelerating the filtration speed of the tissue dispersion liquid, shortening the operation time, and improving the work efficiency.

[0033] As embodiment 1, the transmission mechanism can be selected to be connected to a rotating motor on the support frame 8, and the rotating shaft 9 is directly driven to rotate by the rotating motor, thereby driving the eccentric wheel 10 to rotate to approach or move away from the connecting rod 6 (the outer edge of the eccentric wheel 10 can push the connecting rod 6 to move up and down along the movable groove 7 during the rotation process).

[0034] As embodiment 2, the transmission mechanism can be selected to be provided with a first pulley 112, a second pulley 113, and a tensioning wheel 114 on the support frame 8, and a rotating motor is connected to the second pulley 113. Since the belt 111 is wound around and attached to the first pulley 112, the second pulley 113, and the tensioning wheel 114, when the rotating motor is driven, the rotating motor will first drive the second pulley 113 to rotate, and the first pulley 112 and the tensioning wheel 114 will also rotate under the action of the belt 111, so that the first pulley 112 drives the rotating shaft 9 to rotate, thereby linking the eccentric wheel 10. Through the arrangement of the belt 111, since the belt 111 has good elasticity, the transmission process can be made smooth and noiseless.

[0035] In the above technology, the connection method of the tension wheel 114 and the support frame 8 can be: the tension wheel 114 is rotatably set on the fixed shaft 81, and a plurality of limiting holes 82 are set on the support frame 8. The fixed shaft 81 can be connected and limited with any limiting hole 82 to change the relative position of the tension wheel 114 on the support frame 8, thereby adjusting the tension of the belt 111. In addition, when the tension wheel 114 is worn, the fixed shaft 81 can be easily removed and installed from the limiting hole 82 on the support frame 8, thereby replacing a new tension wheel 114, effectively ensuring the tensioning performance of the tension wheel 114 on the belt 111.
