[0024] Referring to Figures 1 to 4 The clamping mechanism 2 can be used to rigidly clamp and fix the tumor sample, and when clamping and fixing irregular tumor samples, the inflation assembly can be used to flexibly clamp the irregular tumor edge, so that the tumor sample can be stably sliced.

[0025] In addition, the collection frame 4 can be used to collect the sliced tumor sample, and the inner wall of the collection frame 4 can be additionally provided with a sterilization component to sterilize the sliced tumor sample. The tumor sample is usually refrigerated and fixed, so the tumor sample is usually rigid and solid after refrigeration, which facilitates slicing of the tumor sample.

[0026] The clamping mechanism 2 further comprises two first guide grooves 202 formed on the upper surface of the box body 1, and a connecting rod 203 in sliding cooperation with the first guide grooves 202 and fixedly connected with the bottom surface of the clamping frame 201, and the clamping mechanism 2 further comprises a driving assembly for driving the two clamping frames 201 to move closer to or away from each other.

[0027] The clamping mechanism 2 can be used to rigidly clamp and fix the tumor sample, and the driving assembly can be used to drive the two first guide grooves 202 to move closer to or away from each other, so that the tumor sample can be clamped and fixed.

[0028] In addition, one side of the two clamping frames 201 is arc-shaped, which can better clamp and fix the tumor sample and avoid falling off during clamping of irregular tumors. The first guide grooves 202 and the connecting rod 203 can be used to improve the stability of the clamping frame 201 during movement.​

[0029] The driving assembly comprises a double-output-shaft motor 204 mounted on the bottom wall in the box body 1, and the two output shafts of the double-output-shaft motor 204 are fixedly connected with lead screws 205, and the outer surfaces of the lead screws 205 are threadedly connected with lead screw seats 206 fixedly connected with the lower ends of the connecting rods 203.

[0030] By arranging the driving assembly and the lead screws 205 in the driving assembly, the thread directions of the two lead screws 205 are opposite, so that the two clamping frames 201 can be driven to move close to or away from each other, thereby facilitating clamping and fixing of the tumor sample.

[0031] When clamping and fixing the tumor sample, the double-output-shaft motor 204 is started, the two output shafts of the double-output-shaft motor 204 drive the two lead screws 205 to rotate, and since the thread directions of the two lead screws 205 are opposite, the two lead screw seats 206 can be driven to move close to or away from each other, thereby driving the clamping movement of the clamping frame 201 through the connecting rod 203.

[0032] The driving assembly further comprises a guide strip 207 fixed to the bottom wall in the box body 1 and slidably matched with the bottom surface of the lead screw seat 206, and a second guide groove 208 opened on the upper surface of the box body 1, and the bottom surface of the clamping frame 201 is fixedly connected with a guide rod 209 slidably matched with the second guide groove 208.

[0036] By arranging the inflation assembly, when clamping the irregular tumor sample, the inflation assembly can cooperate with the rigid clamping of the clamping frame 201 to perform secondary flexible clamping, so that the irregular tumor sample can be subjected to double clamping effect, and sliding of the irregular tumor sample during clamping can be avoided.

[0037] In addition, the inflatable pad 2011 in the inflatable assembly can be in contact with the tumor sample with a protruding edge when clamping the irregular tumor sample, so that the inflatable pad 2011 can automatically fill and clamp the edge of the irregular tumor sample after inflation.

[0038] The inflatable assembly further comprises a ventilation hole 2012 formed in the outer surface of the clamping frame 201, and a protective plate 2013 hinged to the outer surface of the clamping frame 201.

[0039] By arranging the inflatable assembly and the ventilation hole 2012 in the inflatable assembly, the air pump 2010 can easily extract or discharge external air, so that the extracted air can be transmitted to the inflatable pad 2011 by the air pump 2010 to flexibly clamp the irregular tumor.

[0040] In addition, the arrangement of the protective plate 2013 can facilitate the disassembly, replacement and maintenance of the air pump 2010, thereby improving the practicability of the whole device.

[0042] Reference Figures 1 to 4 The arrangement of the slicing mechanism 3 can facilitate slicing of the clamped tumor sample, and the arrangement of the adjusting assembly can facilitate manual adjustment of the angle of the blade 306. The tumor sample can be sliced by adjusting the angle of the blade 306, and the blade 306 can be retracted and turned over to the upper side after the slicing, thereby avoiding scratching the worker.

[0043] The adjusting assembly comprises a frame 301 fixed to the upper surface of the box body 1, and a fixed block 302 fixed to the top wall in the frame 301. The inner wall of the fixed block 302 is rotatably connected with a double-headed threaded rotating rod 303, and the outer surface of the double-headed threaded rotating rod 303 is fixedly connected with a fixed ring 304. The adjusting assembly further comprises an electric push rod 305 installed on the bottom surface of the fixed ring 304, and the output end of the electric push rod 305 is fixedly connected with the blade 306.

[0045] In addition, the screw ring 307 is threadedly connected with the threads on the edge of the double-threaded rotating rod 303, and when the screw ring 307 is rotated, it can be moved to a position in close contact with the fixed block 302, so as to fix the angle of the fixed block 302, and the way that the blade 306 is installed on the output end of the electric push rod 305 can automatically adjust the angle of the blade 306 during installation, so as to facilitate subsequent slicing of the tumor sample.

[0046] Working principle: when slicing the tumor sample, first place the tumor sample between the two frames 301, so as to start the fixed ring 304, the two output rotating shafts of the fixed ring 304 drive the two electric push rods 305 to rotate, and the threads between the two electric push rods 305 are in opposite directions, so as to facilitate the mutual approach of the blades 306, and then the double-threaded rotating rod 303 is driven to slide under the limiting action of the fixed block 302 by the blades 306, so as to rigidly clamp and fix the tumor sample, and when facing irregular tumor samples, the air pump 2010 can be started, the air pump 2010 transmits gas into the inflatable pad 2011 by pumping, and the inflatable pad 2011 is inflated to flexibly clamp the edge of the irregular tumor sample, so as to avoid the tumor sample from falling off, and to ensure stable slicing of the tumor sample.

[0047] After clamping the tumor sample, the electric push rod 305 is started to push the blade 306 to slice the tumor sample, and if the angle of the blade 306 needs to be adjusted to change the slicing position of the tumor sample, the screw ring 307 can be manually rotated, and at the same time the electric push rod 305 is manually deflected to a predetermined position, because the screw ring 307 is threadedly connected with the double-threaded rotating rod 303, the screw ring 307 can be brought close to the fixed block 302 to tightly press the screw ring 307 and the fixed block 302, so as to fix the electric push rod 305 and the blade 306 at a predetermined angle position to slice the tumor sample.
