[0014] The above embodiments of the present invention can achieve the following beneficial effects: (1) The auxiliary long rod is reset and moved at the output end of the bent square tube, which means that the filter square plate on the auxiliary long rod moves close to the first valve, and the specimen sucked into the storage box is placed at the position of the filter square plate close to the first valve, so that the specimen moves. Since the liquid sucked into the storage box is gathered at the bottom, the specimen moves away from the accumulated liquid, so that the specimen can be separated from the liquid, avoiding the specimen being immersed in the liquid for a long time during the sampling process, resulting in dilution of the target components in the specimen, and avoiding the damage to the specimen tissue due to too long immersion time, thereby avoiding interference with the test results, improving the detection accuracy of the device, and avoiding the contamination of the specimen collected by the device, thereby improving the sampling effect of the device; (2) When the specimen to be collected is located between the two clamping blocks, the driving shaft is operated. There is a built-in driving source in the driving shaft for the clamping blocks to rotate on the driving shaft. At this time, the two clamping blocks rotate relative to each other, so that the locking teeth on the two clamping blocks are butted against each other, and the locking teeth on the two clamping blocks are staggered, so that they are meshed and the specimen is clamped, thereby avoiding the phenomenon of specimen dislocation due to non-human factors or other situations when collecting diseased tissues, and avoiding the error of the collected diseased tissues due to excessive external force or pulling during the collection process, reducing the limitations of the device when in use, and improving the sampling effect of the device; so that the stability of the specimen when being sampled is improved; (3) Start the driving motor so that its output end drives the reversing blades to rotate, so that the suction force generated by the rotation acts on the outside through the intake square hole, thereby sucking the excised specimen located between the two clamping blocks into the storage box through the intake square hole and acting on the filter square plate, so that the collected specimen is stored in the storage box, avoiding contact with the outside world when the specimen is separated from the organ during the collection process, which may cause changes in the target components in the specimen. This not only improves the sampling effect of the device on the specimen, but also avoids contamination of the specimen and improves the accuracy of its detection. It is worth mentioning that when the intake square hole at one clamping block sucks the specimen into the storage box, the reversing blades at the other clamping block can reverse and generate a blowing force to blow the specimen into the box, thereby accelerating the collection speed of the specimen, thereby reducing the limitations of the device during use. (4) When the guide cylinder moves within the guide cylinder, the guide cylinder drives the meshing guide gear to rotate under the action of the bending rack, so that the meshing auxiliary rack moves, and then the auxiliary square plate on it moves within the bending square cylinder, so that the gas in the bending square cylinder is squeezed to its output end, thereby pushing the auxiliary long rod at the output end of the bending square cylinder to move, so that the filter square plate moves away from the first valve, so that the space that can accommodate the specimen becomes larger, avoiding the collected specimen from being unable to enter the storage box due to its too large size, thereby reducing the limitations of the device during use; at the same time, the buffering force brought by the positioning spring can also avoid the specimen from being damaged due to excessive contact with the filter square plate when entering the storage box, thereby reducing the impact force brought by the contact between the specimen and the filter square plate, thereby effectively protecting the collected diseased tissue, and improving the use effect of the device; (5) The two threaded driving sliders are limited in relative movement in the driving slide groove, so that the two clamping blocks move relative to each other. Since the locking teeth on them cannot move further due to mutual meshing, the guide cylinder in the storage square groove is limited in movement at the guide cylinder. At this time, the guide spring is in a buffering state, thereby strengthening the connection strength of the two mutually meshing locking teeth, avoiding dislocation or shaking of the clamped diseased tissue, avoiding the movement of the specimen after being limited, etc., resulting in errors in the collection area, and improving the accuracy of specimen sampling; at the same time, when the locking teeth and the triggering pieces on the opposite sides of the storage square groove are in contact, it means that the two locking teeth have clamped the diseased tissue in place, avoiding the dislocation of the specimen due to failure to clamp it, and reducing the limitations of the device when in use; (6) The limit plate drives the cutting knife to move under the action of the blocking cylinder and the blocking spring. At this time, after the diseased tissue is clamped, its root will be located at a place far away from the U-shaped base and the cutting knife is located at this place, so that the two cutting knives can move relative to each other, so that the diseased tissue can be removed and separated from the organ, and the collection operation of the diseased tissue can be completed; the buffering force brought by the blocking spring can also prevent the two cutting knives from being damaged by the impact force caused by excessive strength when they come into contact, thereby reducing the limitations of the device during use and prolonging the service life of the cutting knife. It avoids the traditional clamp body from pulling the specimen after clamping it, which causes tearing at this place. The specimen is decisively removed at the organ with the cutting knife, which enhances the sampling efficiency and improves the sampling effect of the device; (7) When the two clamping blocks on the clamping and sampling device are reset and moved after the sampling operation is completed, the gas originally passing through the transfer air box is reset. A part of the reset gas will enter the active U-tube and act on one end of the active U-column, causing it to move closer to the partition, and the other end of the active U-column to move within the driven cylinder. As a result, when the suction force generated by it acts on the storage square box, the adsorption effect of the storage square box on the specimen is enhanced, the collection speed of the specimen is increased, and the use effect of the device is further improved.

At this time, by operating the driving rotating shaft 2, there is a built-in driving source (not shown in the figure) in the driving rotating shaft 2 to allow the clamping blocks 3 to rotate on the driving rotating shaft 2. At this time, the two clamping blocks 3 rotate relatively, so that the locking racks 4 on the two clamping blocks 3 are arranged in butt joint, and the locking racks 4 on the two clamping blocks 3 are arranged in a staggered manner, so that they are meshed, so as to clamp the specimen, avoiding the phenomenon of specimen dislocation caused by non-human factors or other situations during the collection of diseased tissues, and at the same time avoiding the error of the collected diseased tissues caused by excessive external force or pulling during the collection process, reducing the limitation of the device during use, and at the same time improving the sampling effect of the device; improving the stability of the specimen when being sampled; After the locking racks 4 on the two clamping blocks 3 are meshed, by starting the built-in driving source (not shown in the figure) at the driving lead screw 9, the two driving sliders 8 connected by threads move relatively in the driving chute 7 in a limited way, so that the two clamping blocks 3 move relatively. Since the locking racks 4 on them cannot move continuously due to mutual meshing, at this time, the guiding cylinder 12 in the storage square groove 5 moves in a limited way at the guiding cylinder 11, and at this time, the guiding spring 13 is in a buffered state, thus strengthening the connection strength of the two mutually meshed locking racks 4, avoiding the phenomenon of dislocation or shaking of the clamped diseased tissues, and avoiding the situation that the specimen moves after being limited, resulting in an error in the collection area, and improving the accuracy of the specimen during sampling; at the same time, when the locking rack 4 contacts the touch piece 17 at the opposite surface of the storage square groove 5, it means that the two locking racks 4 have clamped the diseased tissues in place, avoiding the situation that the specimen is not clamped and causing its dislocation, etc., and reducing the limitation of the device during use.

[0019] The storage partition unit of this embodiment includes a storage square box 18 installed in the storage square groove 5, and a gas-making and inhalation mechanism is arranged in the storage square box 18; intake square holes 19 are provided on the opposite surfaces of the two clamping blocks 3, and the intake square holes 19 are communicated with the storage square box 18; a first valve is further installed on the intake square holes 19; a filter empty square plate 20 with the same size as the storage square box 18 is installed in the storage square box 18, a positioning square column 21 is installed on the side of the filter empty square plate 20 away from the first valve, and a positioning square cylinder 22 is slidably connected to the positioning square column 21, and the positioning square cylinder 22 is fixedly installed in the storage square box 18; a positioning spring 23 is arranged in the positioning square cylinder 22, one end of the positioning spring 23 is fixedly connected to the inner bottom surface of the positioning square cylinder 22, and the other end is fixedly connected to the positioning square column 21; a auxiliary driving long rod 24 is further installed on the side of the filter empty square plate 20 close to the first valve; the storage partition unit further includes an auxiliary driving rack 25, and the auxiliary driving rack 25 is meshed with the guiding gear 15; an auxiliary driving base 26 is slidably connected to the auxiliary driving rack 25, and the auxiliary driving base 26 is fixedly connected in the storage square groove 5; an auxiliary driving square plate 27 is further installed on the side of the auxiliary driving rack 25 close to the locking rack 4, and the input end of a bent square cylinder 28 is slidably connected to the auxiliary driving square plate 27, and the bent square cylinder 28 is installed on the storage square box 18; the output end of the bent square cylinder 28 is located in the storage square box 18 and faces the top of the filter empty square plate 20; the output end of the bent square cylinder 28 is slidably connected to the auxiliary driving long rod 24; When the specimen is collected and the specimen is inhaled into the storage box 18 by operating the gas inhalation mechanism, since the collected specimen is in different organs, it will contain natural physiological fluids or flushing fluids mixed together. When it reaches this step, it means that the sampling operation of the specimen has been completed, and the two clamping blocks 3 are reset to move to wait for the next sampling operation. At this time, the guiding cylinder 12 and the guiding column 11 are reset to move. Under the action of the bending rack 14, the guiding gear 15 is reset to rotate, so that the guiding gear 15 meshes with the auxiliary rack 25 and moves back on the auxiliary base 26. Then the auxiliary square plate 27 on the auxiliary rack 25 moves back in the input end of the bending square cylinder 28. Then the gas originally gathered at the output end of the bending square cylinder 28 is drawn to the vicinity of the input end of the bending square cylinder 28. Under the action of the suction force, the auxiliary long rod 24 moves back at the output end of the bending square cylinder 28, which also means that the filtering square plate 20 on the auxiliary long rod 24 moves closer to the position of the first valve. And the specimen inhaled into the storage box 18 is placed at the position of the filtering square plate 20 close to the first valve, so that the specimen moves. Since the liquid inhaled into the storage box 18 accumulates at the bottom, the specimen moves away from the accumulated liquid, so that the specimen can be separated from the liquid, avoiding the dilution of the target components in the specimen caused by the specimen being immersed in the liquid for a long time during the sampling process, and at the same time avoiding the damage of the specimen tissue caused by the specimen being soaked for too long, thus avoiding interfering with the test results, improving the detection accuracy of the device, and at the same time avoiding the contamination of the specimen collected by the device, improving the sampling effect of the device; It is worth mentioning that when the device collects the specimen, when the clamping and sampling device clamps the specimen and makes the guiding column 11 move limit in the guiding cylinder 12, the guiding column 11 drives the meshing guiding gear 15 to rotate under the action of the bending rack 14, so that it meshes with the auxiliary rack 25 and moves, and then the auxiliary square plate 27 on it moves limit in the bending square cylinder 28, so that the gas in the bending square cylinder 28 is squeezed to its output end, thus pushing the auxiliary long rod 24 at the output end of the bending square cylinder 28 to move, making the filtering square plate 20 move away from the first valve, and making the space that the specimen can accommodate larger, avoiding the specimen being unable to enter the storage box 18 due to its too large size, and reducing the limitation of the device in use; at the same time, the buffer force brought by the positioning spring 23 also avoids the excessive contact force between the specimen and the filtering square plate 20 when the specimen enters the storage box 18, reducing the impact force brought by the contact between the specimen and the filtering square plate 20, effectively protecting the collected diseased tissue, and improving the use effect of the device.

However, the second valve provided in the L-shaped pipeline 33 has not been opened at this time, and the middle end of the transfer gas box 32 can expand, so that the gas continues to enter the transfer gas box 32, causing the middle end of the transfer gas box 32 to expand. At this time, when the control sampling device completes the clamping operation of the sample to be collected, the guide cylinder 11 moves within the guide cylinder 12, so that the gas in the guide cylinder 12 gradually enters the transfer gas box 32 through the double-ended pipeline 29 and the gas pipeline 31. When the control board receives the signal sent by the two trigger plates 17 after contact, the second valve is opened through the control board, so that the gas stored in the transfer gas box 32 finds the discharge port and quickly rushes to the output end of the L-shaped pipe 33, and acts on the limit column 34, so that it slides at the output end of the L-shaped pipe 33, and drives the limit horizontal plate 35 on the limit column 34 to move away from the L-shaped pipe 33, so that the limit horizontal plate 35 moves to the upper limit position on the limit square column 37 through the limit square plate 36, so that the limit The spring 38 is in a buffering state, so that when it is reset, the gas in the L-shaped pipe 33 can be brought back into the guide cylinder 12; the limit cross plate 35 drives the cutting knife 40 to move under the action of the blocking cylinder 39 and the blocking spring 42. At this time, after the diseased tissue is clamped, its root will be located at a place far away from the U-shaped base 1, and the cutting knife 40 is at this place, so that the two cutting knives 40 move relative to each other, so that the diseased tissue can be removed and separated from the organ, and the collection operation of the diseased tissue can be completed; the buffering force brought by the blocking spring 42 can also prevent the impact force caused by excessive strength when the two cutting knives 40 contact to damage the cutting knives 40, reduce the limitations of the device when in use, and increase the service life of the cutting knife 40, avoid the traditional clamp body after clamping the specimen by pulling to sample, resulting in tearing at this place, and decisively use the cutting knife 40 to remove the specimen at the organ to enhance the sampling efficiency and improve the sampling effect of the device.

[0021] The air suction mechanism of this embodiment includes a driving motor 43 installed in the storage box 18, the output end of the driving motor 43 faces the first valve and is also equipped with a reversing fan blade 44, and the reversing fan blade 44 is located between the filter square plate 20 and the inner bottom surface of the storage box 18; the air suction mechanism also includes an active U-tube 45, the input end of the active U-tube 45 is installed on the outer wall of the gas pipeline 31; the output end of the active U-tube 45 faces the partition 6; one end of the active U-column 46 is also slidably connected to the output end of the active U-tube 45; the other end of the active U-column 46 faces the storage box 18 and is also slidably connected to a driven cylinder 47, which is fixedly installed on the side wall of the storage box 18; the storage box 18 is connected to the driven cylinder 47; a driven base 48 is installed on the outer wall of the output end of the active U-tube 45, and the driven base 48 is installed in the storage square groove 5; the active U-column 46 and the driven base 48 are slidably matched; When the clamping and sampling device has clamped the diseased tissue to be collected, and after the blocking and cross-cutting assembly has cut off the clamped diseased tissue, it means that the two trigger pieces 17 have come into contact and sent a signal to the controller. At this time, the controller sends a start signal to the first valve to open it. By starting the drive motor 43, its output end drives the reverse fan blade 44 to rotate, and the suction generated during its rotation acts on the outside through the intake square hole 19. Thus, the excised specimen located between the two clamping blocks 3 is sucked into the storage square box 18 through the intake square hole 19 and acts on the filter square plate 20, so that the collected specimen is stored in the storage square box 18, avoiding contact with the outside world when the specimen is separated from the organ during and after collection, which may cause changes in the target components in the specimen. This not only improves the sampling effect of the device on the specimen, avoids specimen contamination, and improves the accuracy of its detection; It is worth mentioning that when the intake square hole 19 at one clamping block 3 sucks the specimen into the storage square box 18, the reverse fan blade 44 at the other clamping block 3 can reverse to generate a blowing force to blow the specimen in, accelerating the storage speed of the specimen, thereby reducing the limitations of the device during use; It is worth mentioning that when the two clamping blocks 3 on the clamping and sampling device are reset and moved after the sampling operation is completed, the gas originally passing through the transfer air box 32 is reset. The reset part of the gas will enter the active U-tube 45 and act on one end of the active U-column 46, causing it to move closer to the partition 6, and the other end of the active U-column 46 to move inside the driven cylinder 47. Thus, when the suction force generated by it acts on the storage square box 18, the adsorption effect of the storage square box 18 on the specimen is enhanced, the collection speed of the specimen is increased, and the use effect of the device is further improved.

[0022] In some embodiments, it further includes a processor (not shown in the figure) and an ultrasonic sensor (not shown in the figure). The ultrasonic sensor is directed at the blocking and cross-cutting assembly. The processor is signal-connected to the ultrasonic sensor. The ultrasonic sensor continuously sends ultrasonic signals to the blocking and cross-cutting assembly, receives ultrasonic data and sends it to the processor. The processor is built-in with a trained variational autoencoder and a deep neural network. The input of the variational autoencoder is ultrasonic data, and the output of the variational autoencoder is an internal simulation image of the blocking and cross-cutting assembly. The input of the convolutional neural network is the internal simulation image of the blocking and cross-cutting assembly, and the output of the convolutional neural network is the degree of structural damage of the blocking and cross-cutting assembly. If the degree of structural damage of the blocking and cross-cutting assembly is greater than the threshold, the processor sends an alarm signal to the control port of the management user.
