Since the outer surface of the supporting ring 110 is attached to the inner wall of the screen 104, the isolation film 108 blocks the screen holes on the outer surface of the screen 104, so that the liquid cannot flow out after passing through the filter screen. When the supporting ring 110 is deformed under stress, the isolation film 108 below is deformed accordingly, and the liquid in the separation cylinder 1 can flow out after passing through the screen 104.

The bottom end of the collecting pipe 201 is sleeved with the sample pipe 11, and the sample pipe 11 is provided with a screen pipe 12; after the tumor tissue enters the sample pipe 11 along with the diluent, the screen pipe 12 can be directly pulled out to separately take out the tumor tissue; the bottom end of the collecting pipe 201 is sleeved with an elastic soft rubber sleeve, and the sample pipe 11 is stably fixed by friction force after penetrating into the soft rubber sleeve.

[0025] As shown in Figure 1 the outer surface of the separation cylinder 1 can be fixedly installed with a control terminal by means of a clamp, which is used for controlling the start and stop of the application; when the unlocking buckle 3 starts to move upward, the control terminal controls the driving motor 4 to stop working at this time.

[0026] The working principle of the application is as follows: During use, the tumor tissue and the diluent are poured into the interior of the separation cylinder 1, and then the driving motor 4 is started by the control unit. The driving motor 4 drives the screen 104 to rotate through the driving rod 101. At this time, the tumor tissue and the diluent inside the separation cylinder 1 begin to flow inside the separation cylinder 1 under the rotation of the screen 104. The tumor tissue contacts the reamer 103 under the action of centrifugal force and is thereby broken. After the driving motor 4 has run for a period of time, the tumor tissue is basically broken, and the unlocking buckle 3 is lifted upward (the unlocking buckle 3 must be kept in the lifted state at all times). The driving motor 4 stops working at this time. After the tumor tissue is mixed with the diluent, the diluent will reduce the viscosity of the tissue surface, so that the mucus and the tissue are separated. The mucus and fat on the tumor tissue will be separated. The mass of the fat is less than that of the diluent, so it will float on the diluent, and solid substances such as the tumor tissue will be deposited at the bottom of the separation cylinder 1 (see Figure 13 state diagram); When the unlocking buckle 3 moves upward, it drives the center rod 102 to move. At this time, the bite block 107 moves with the center rod 102. The protrusion on its outer surface passes through the notch at the bottom end of the driving rod 101. Since the driving motor 4 no longer provides power, the screen 104 continues to rotate under the action of inertia. When the screen 104 rotates, it drives the center rod 102 to rotate through the driving rod 101. At this time, when the center rod 102 rotates, it drives the passive sleeve 308 to rotate through the rectangular block 309. During the rotation of the passive sleeve 308, the traction belt 306 is twisted and deformed, and drives the movable sleeve 311 to move downward. At this time, the clamping plate 314 is connected to the movable sleeve 311, and the movable plate 304 also moves downward. The downward movement of the movable plate 304 drives the abutment block 305 to move. The sealing capsule 303 moves downward under the friction force of the abutment block 305 and begins to absorb and collect the dilution liquid containing a large amount of light substances such as fat in the upper half of the separation cylinder 1; After the locking cam 314 is unlocked, the locking cam 314 is unlocked and the locking cam 316 is unlocked, and the locking cam 316 is unlocked, so that the locking cam 316 is unlocked and the locking cam 316 is unlocked. Meanwhile, the passive sleeve 308 rotates and pulls the support ring 110 through the traction line 111, the uniform stress state of the support ring 110 is broken, and thus starts to deform, the isolation film 108 changes in shape, so that the dilution liquid in the lower half area of the separation cylinder 1 flows to the inside of the collection basin 112 through the screen 104, and then the dilution liquid in the infiltration pipe 203 starts to flow, at this time, the internal pressure of the infiltration pipe 203 is less than the external pressure, the passive plug 204 moves towards the infiltration pipe 203 under the action of air pressure, the passive plug 204 moves through the transmission rod 205 to drive the triangular block 206, so that the lifting rod 207 is lifted under the pushing of the triangular block 206, the sealing cover 202 moves upwards under the action, so that the tumor tissue flows into the inside of the collection pipe 201 with the dilution liquid, and then enters the inside of the sample tube 11, the tumor tissue is intercepted by the screen pipe 12, and the liquid part is collected by the sample tube 11; Then after the tumor is recovered, the unlocking buckle 3 is loosened, the occlusion block 107 is disconnected with the driving rod 101, the traction belt 306 releases the elastic force due to the elasticity of the traction belt 306 and the elastic sheet 313, the movable sleeve 311 moves upwards, the clamping plate 314 is connected with the movable sleeve 311 again at this time, the movable plate 304 starts to move upwards, the abutment block 305 is gradually reset in the upward movement of the movable sleeve 311, the support ring 110 also has elastic force, and then returns to the initial state, and the sealing cover 202 also falls back to the initial position under the action of gravity after the lifting force is removed, and the passive plug 204 also returns to the initial state; The tumor sample separation operation is completed.

[0027] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
