[0048] The grabbing assembly includes a U-shaped frame 16 and a grabbing plate 17. A first support rod 18 is symmetrically hinged on the inner wall of the U-shaped frame 16.

[0049] A refrigeration component is fixedly connected to the inner wall of the slice storage box 1 by bolts. In this embodiment, the refrigeration component is a semiconductor refrigeration plate, and the controller is used to control the opening and closing of the semiconductor refrigeration plate; a humidification pipe 27 is fixedly welded and connected to the outer wall of the slice storage box 1, and the end of the humidification pipe 27 away from the slice storage box 1 is connected to a humidifier, and the controller is used to control the opening and closing of the humidifier; a dehumidification pipe 28 is also fixedly welded and connected to the outer wall of the slice storage box 1, and the end of the dehumidification pipe 28 away from the slice storage box 1 is connected to a dehumidifier, and the controller is used to control the opening and closing of the dehumidifier.

[0050] An inclined placement groove 29 is provided on the inner bottom wall of the storage and access box 3 near the retrieval hole 5, and a plurality of positioning grooves are provided on the inner bottom wall of the slice storage box 1 along its circumference, and the slice boxes 2 are all placed on the positioning grooves; a temperature sensor and a humidity sensor are fixedly connected to the inner wall of the slice storage box 1 by bolts, and a controller is used to receive temperature signals and humidity signals sent by the temperature sensor and the humidity sensor; a display screen 30 is fixedly connected to the outer wall of the drive box 6 by bolts, the display screen 30 is electrically connected to the controller, and the display screen 30 is used to display parameter signals sent by the controller; a keyboard 31 is fixedly connected to the outer wall of the display screen 30 by bolts, and the controller is used to receive setting signals sent by the keyboard 31; a sealing cover 32 is hinged on the retrieval hole 5.

[0051] The specific implementation process is as follows:

[0052] When the slice box 2 needs to be stored, the medical staff first puts the pathological slices to be stored into the slice box 2, opens the sealing cover 32, and then puts the slice box 2 into the access hole 5; then the medical staff inputs the number or location information of the slice box 2 through the keyboard 31, and after receiving the instruction, the controller starts to execute the slice box 2 storage operation.

[0053] The controller sends a control signal to control the driving member 7 to start. In this embodiment, the driving member 7 is a servo motor.

[0054] The servo motor drives the spline shaft 8 to rotate. Since the bottom of the telescopic cylinder 9 and the spline groove on the spline shaft 8 slide vertically together, under the action of the spline groove limiting the telescopic cylinder 9, the rotation of the spline shaft 8 can drive the telescopic cylinder 9 to rotate. At the same time, the servo motor can control the rotation angle. At this time, the controller sends a control signal to control the servo motor output shaft to drive the spline shaft 8 and then drive the telescopic cylinder 9 to rotate. Since the top of the telescopic cylinder 9 and the electric telescopic rod 11 are fixedly connected, the rotation of the telescopic cylinder 9 can drive the electric telescopic rod 11 to rotate to an initial angle of 0 degrees. In this embodiment, 0 degrees is the position of the pick-up and release hole 5.

[0055] When the electric telescopic rod 11 rotates to the position where the output shaft is aligned with 0 degrees, the controller immediately sends a control signal to control the output shaft of the electric telescopic rod 11 to extend. When the output shaft of the electric telescopic rod 11 is fully extended, the distance from the access hole 5 to the telescopic cylinder 9 is set to the fully extended length of the output shaft of the electric telescopic rod 11. At this time, the U-shaped frame 16 can be moved to both sides of the slicing box 2 by the output shaft of the electric telescopic rod 11 to clamp the slicing box 2. At this time, the controller sends a control signal to control the output shaft of the electric push rod 23 to retract. In this embodiment, the output shaft of the electric push rod 23 is initially extended.

[0056] When the output shaft of the electric push rod 23 is retracted, since the fixed block 24 is fixedly connected to the output shaft of the electric push rod 23 by bolts, the fixed block 24 can be retracted together with the output shaft of the electric push rod 23. Since the fixed block 24 is provided with a slide groove 25, the slider 22 slides with the slide groove 25. At the same time, since the first support rod 18 and the second support rod 20 are hinged to the inner wall of the U-shaped frame 16, the slider 22 is limited by the slide groove 25. When the fixed block 24 is retracted along with the output shaft of the electric push rod 23, the slider 22 can drive the connecting rod 19 to move toward the direction of the electric push rod 23. Since the first support rod 18 and the second support rod 20 are hinged to the connecting rod 19, the first support rod 18 and the second support rod 20 move toward the middle of the U-shaped frame 16 driven by the connecting rod 19. The support plate 21 to which the first support rod 18 and the second support rod 20 are fixedly connected is then driven to move toward the middle of the U-shaped frame 16. At this time, the support plate 21 can drive the grab plate 17 to move toward the middle of the U-shaped frame 16, so that the grab plate 17 can have a grab function on the two side walls of the slice box 2, so that the slice box 2 can be transported to the pick-up and placement position. At the same time, the inclined slide groove 25 can provide a certain buffer for the movement of the grab plate 17 grabbing the slice box 2, which can reduce the vibration of the slice box 2 caused by the grab plate 17 vertically grabbing the slice box 2, thereby reducing the impact on the slicing quality; at the same time, the damping shock absorber 26 between the support plate 21 and the grab plate 17 can further reduce the vibration of the slice box 2 caused by the grab plate 17 during the grabbing process.

[0057] When the output shaft of the electric push rod 23 is retracted to the maximum stroke, the controller sends a control signal to control the first solenoid valve 13 to open. At this time, the air inlet pipe 12 connected to the bottom of the telescopic cylinder 9 is connected to the positive pressure system. At this time, the positive pressure of the positive pressure system can enter the slide 10. Since the outer wall of the telescopic cylinder 9 and the inner wall of the slide 10 are vertically slidably matched, and at the same time, since the bottom wall of the telescopic cylinder 9 and the spline groove of the spline shaft 8 are slidably matched, the positive pressure in the slide 10 can drive the telescopic cylinder 9 to extend upward and then drive the electric telescopic rod 11 to move from the through hole 4 to the slice storage box 1. By controlling the first solenoid valve 13 to open for 5s and then close it, the telescopic cylinder 9 can be extended to the maximum stroke, and then the slice box 2 is transported to the slice storage box 1.

[0058] Since a plurality of positioning grooves are provided along the circumference of the inner bottom wall of the slice storage box 1, in the present embodiment, the interval angle of adjacent positioning grooves is 18 degrees; at this time, the controller sends a control signal to control the servo motor to rotate 18 degrees, at this time, the output shaft of the electric telescopic rod 11 can be aligned with the positioning groove, at this time, the controller sends a control signal to control the output shaft of the electric telescopic rod 11 to extend to the maximum stroke, at this time, the slice box 2 is just located directly above the positioning groove, and the controller immediately sends a control signal to control the output shaft of the electric push rod 23 to extend, at this time, the grab plate 17 moves away from the middle of the U-shaped frame 16 under the action of the extension of the output shaft of the electric push rod 23, so that the grab plate 17 releases the slice box 2, and at this time, the controller records that the corresponding rotation angle of the slice box 2 is 18 degrees, and then the controller sends a control signal to control the output shaft of the servo motor to rotate to 0 degrees.

[0059] When the medical staff needs to take out the slice box 2, the controller only needs to send a control signal to control the servo motor output shaft to rotate 18 degrees to rotate the electric telescopic rod 11 to align with the slice box 2. When the grab plate 17 stably grabs the slice box 2, the controller sends a control signal to control the second solenoid valve 15 to open for 5s. At this time, since the air outlet pipe 14 connected to the bottom of the telescopic cylinder 9 is connected to the negative pressure system, the negative pressure of the negative pressure system can take away the air pressure in the slide cylinder 10, and the telescopic cylinder 9 thus realizes the contraction function. After 5s, the second solenoid valve 15 is closed, and the controller immediately sends a control signal to control the servo motor output shaft to rotate to 0 degrees. At this time, the controller sends a control signal to control the output shaft of the electric telescopic rod 11 to extend to the maximum stroke. At this time, the slice box 2 is just above the pick-up and release hole 5. At this time, the grab plate 17 moves away from the middle of the U-shaped frame 16 under the action of the extension of the output shaft of the electric push rod 23, so that the grab plate 17 releases the slice box 2, and the medical staff takes out the slice box 2 from the pick-up and release hole 5, thereby realizing the function of accurately picking and placing the specified slice box 2.

[0060] The setting of the semiconductor refrigeration chip can ensure that the temperature in the slice storage box 1 is maintained within an appropriate range, thereby preventing the pathological slices from being deteriorated or damaged due to excessive temperature; through the precise control of the semiconductor refrigeration chip by the controller, the temperature in the slice storage box 1 can be adjusted according to actual needs to meet the storage requirements of different pathological slices.

[0061] The setting of the humidifier can ensure that the humidity in the slice storage box 1 is maintained within an appropriate range, thereby preventing the pathological slices from drying out or deforming due to too low humidity; through the precise control of the humidifier by the controller, the humidity in the slice storage box 1 can be adjusted according to actual needs to maintain the optimal storage state of the pathological slices; the setting of the dehumidifier can ensure that the humidity in the slice storage box 1 is not too high, thereby preventing the pathological slices from becoming moldy or damaged due to excessive humidity.

[0062] The setting of the temperature sensor and humidity sensor can monitor the temperature and humidity environment in the slice storage box 1 in real time; the controller determines whether the current environment meets the storage requirements of pathological slices based on the received signals, and adjusts the working status of the semiconductor refrigerator, humidifier and dehumidifier accordingly to maintain the optimal storage environment.

[0063] The display screen 30 allows medical personnel to intuitively view the current operating status of the device, including key information such as temperature, humidity, and position of the slice box 2, which facilitates timely monitoring and adjustment, thereby improving the convenience and transparency of operation.

[0064] Embodiment 2:

[0065] The difference from Example 1 is that a photoelectric sensor is fixedly connected to the inner wall of the positioning groove by bolts, and the controller is used to receive the photoelectric signal of the photoelectric sensor.

[0066] The specific implementation process is as follows: the photoelectric sensor can monitor the presence status of the slice box 2 in the positioning groove in real time; when the slice box 2 is placed in or taken out, the photoelectric sensor will send a corresponding signal to the controller, and the controller will judge the position and status of the slice box 2 according to the signal, thereby realizing accurate management and tracking of the slice box 2, and improving the accuracy and reliability of the access operation.

[0067] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
