Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection equipment, in particular to a paraffin tissue sectioning machine facilitating separation. BACKGROUND

[0002] The paraffin tissue sectioning machine is the core equipment in the field of pathological diagnosis, and its core function is to make thin sections of paraffin tissue blocks processed by fixation, dehydration and embedding for observing cell morphology and pathological characteristics under a microscope. In the existing paraffin tissue sectioning machine, the sample clamp drives the paraffin tissue block to reciprocatingly ascend and descend by a hand wheel or semi-automatic control to make the tissue block precisely contact with the sectioning knife on the knife holder, so as to realize sectioning. The sectioning process includes rough sectioning and thin sectioning. The paraffin waste generated in the two stages is naturally collected by the lower waste groove, so as to ensure the continuity of the sectioning process and the neatness of the workbench.

[0003] In the paraffin sectioning process, the sectioning knife will be slightly worn by long-term friction with the hard paraffin tissue block, and micron-level metal debris will be formed. Such metal debris is easy to fall into the waste groove together with the paraffin waste generated by cutting. The conventional processing method of the existing pathological laboratory is to collect all the waste and directly incinerate and dispose according to the standard of pathological medical waste without metal impurities. However, in the incineration process, the metal debris with high temperature resistance will scratch the inner lining of the incinerator and wear the grate components, which not only shortens the service life of the incineration equipment, but also may cause the sealing performance of the furnace body to decrease and increase the equipment operation and maintenance cost. At the same time, the core function of the rough sectioning stage is to trim the shape of the paraffin tissue block and calibrate the flatness of the sectioning surface. The waste generated in this stage is mainly pure paraffin without pathological tissue residues. Such pure paraffin waste can be purified by melting, filtering and low-temperature cooling forming processes, and then be reused in the scenes of rough sectioning trimming, small-size tissue embedding filling or teaching experiments. If it is incinerated together with the mixed waste containing metal debris, it will cause unnecessary waste of paraffin resources and indirectly increase the consumable procurement cost of pathological detection.

DETAILED DESCRIPTION

[0018] In order to better understand the technical content of the present application, a specific embodiment is provided below, and the present application is further described in conjunction with the accompanying drawings.

[0019] Reference Figs. 1 to 4 The present application provides a paraffin tissue sectioning machine convenient to separate, comprising a body 1, a sample clamp 2, a driving mechanism, a scrap groove 3, a mounting table 4, a tool holder 5, a U-shaped partition 6 and a separation and collection mechanism, the surface of the body 1 is provided with a control panel 7, the sample clamp 2 is movably arranged on the side wall of the body 1, the driving mechanism is arranged in the body 1 for driving the sample clamp 2 to move up and down, the scrap groove 3 is arranged on the side wall of the body 1, the mounting table 4 is arranged in the scrap groove 3, the tool holder 5 is obliquely arranged on the mounting table 4 and located below the sample clamp 2, the U-shaped partition 6 is arranged in the scrap groove 3 and divides the scrap groove 3 into a metal impurity cavity 8, a separation cavity 9 and a pure paraffin cavity 10 together with the mounting table 4, the separation cavity 9 is located below the tool holder 5, and the metal impurity cavity 8 and the pure paraffin cavity 10 are located on both sides of the mounting table 4 and the separation cavity 9; the separation and collection mechanism comprises a magnetorheological fluid 11, an electromagnetic coil 12, an electric sliding table 13, a bearing plate 14 and a grabbing mechanism, the magnetorheological fluid 11 is arranged in the separation cavity 9, the electromagnetic coil 12 is arranged on the bottom surface of the scrap groove 3 and located below the separation cavity 9, the magnetic field strength generated by the electromagnetic coil 12 gradually weakens from the metal impurity cavity 8 to the pure paraffin cavity 10, the electric sliding table 13 is symmetrically arranged on the inner wall of the scrap groove 3 and has a height greater than that of the U-shaped partition 6, the bearing plate 14 is arranged on the mover side wall of the electric sliding table 13, and the grabbing mechanism is arranged on the bearing plate 14 and used for grabbing the scrap in the separation cavity 9, and the control panel 7 is electrically connected with the electromagnetic coil 12, the electric sliding table 13 and the grabbing mechanism respectively.

[0020] When pathological detection is carried out, the corresponding tissue block is embedded in paraffin and prepared into a paraffin tissue block, and then the paraffin tissue block can be fixed on the sample clamp 2 for fixation, and the sample clamp 2 can be driven to reciprocatingly lift and fall by the driving mechanism, and after being adjusted to the position of the knife rest 5, the paraffin tissue block can be contacted with the blade on the knife rest 5 in the reciprocating lifting and falling process of the sample clamp 2, so that the paraffin tissue block is quickly sliced, the sliced tissue piece can be transferred to water to be flattened, and after being subjected to processes such as glass loading and dyeing, the tissue piece is observed under a microscope to realize pathological detection and assist in disease judgment.

[0021] During the slicing process, a large amount of waste will be generated, and since the knife rest 5 is arranged in an inclined manner, the waste will slide downward along the inclined knife rest 5. The knife rest 5 is arranged on the mounting table 4, and the mounting table 4 is located in the waste groove 3, so that the waste can be collected. Only one side of the mounting table 4 is connected with the inner wall of the waste groove 3, which divides the waste groove 3 into a U-shaped space. The U-shaped partition plate 6 is arranged on one side of the mounting table 4 and connected with the waste groove 3, so as to divide the U-shaped space into three parts. The middle part is located on the front side of the mounting table 4, which is a separation cavity 9. The waste falling from the knife rest 5 will directly fall into the separation cavity 9. The spaces on both sides of the mounting table 4 are respectively a metal impurity cavity 8 and a pure paraffin cavity 10. The magnetorheological fluid 11 is arranged in the separation cavity 9, and a plurality of electromagnetic coils 12 are arranged on the bottom surface of the waste groove 3. The magnetic field strengths generated by the plurality of electromagnetic coils 12 are different and change in a gradient manner. The magnetic field strength generated by the electromagnetic coil 12 on one side of the metal impurity cavity 8 is larger, and the magnetic field strength generated by the electromagnetic coil 12 on one side of the pure paraffin cavity 10 is smaller. When the waste enters the separation cavity 9, the electromagnetic coil 12 is not powered, and the magnetorheological fluid 11 is in a liquid state, so that the waste can be scattered in the separation cavity 9. Then, the electromagnetic coil 12 can be powered to form a gradient magnetic field. The waste containing metal impurities will move to the direction of the metal impurity cavity 8 under the action of the gradient magnetic field, and when it moves to an area with a higher magnetic field strength, it will be captured by the solidified magnetorheological fluid 11 and remain fixed. The waste not containing metal impurities will not be affected by the magnetic field, and will only float in an area with a weaker magnetic field strength, where the magnetorheological fluid 11 is still in a liquid state, so as to realize the separation of the waste containing metal impurities and the waste not containing metal impurities.

[0022] After the separation is completed, two electric slides 13 of the side wall of the waste groove 3 can be started, and the electric slides 13 can drive the bearing plates 14 to move.

After the grabbing is completed, the waste can be transferred to the metal impurity cavity 8 and the pure paraffin cavity 10 respectively for collection, so as to process different types of waste. The waste in the metal impurity cavity 8 can be processed after the metal impurities are filtered out, and the paraffin in the pure paraffin cavity 10 does not contain tissue fragments and can be directly melted, filtered and cooled to realize recycling, avoiding waste of resources.

[0023] Preferably, a hand wheel 15 is further included, which is arranged on the side wall of the machine body 1 and connected with the driving mechanism. The hand wheel 15 drives the driving mechanism to operate to realize the lifting of the sample clamp 2.

[0024] The hand wheel 15 can be rotated by the staff. When it is rotated, the reciprocating lifting of the sample clamp 2 can be realized through the driving mechanism. The driving mechanism mainly includes a worm gear reducer, a cam and a clutch. The worm gear reducer reduces the rotation of the hand wheel 15 to drive the rotation of the cam. The cam is connected with the clutch through a lever, and the reciprocating lifting of the sample clamp 2 is realized through the clutch. This mechanism is a common structure in the paraffin sectioning machine, and will not be described here.

[0025] Preferably, the grabbing mechanism includes a double-shaft motor 16, a lead screw 17, a moving plate 18, a first electric push rod 19 and a clamping plate 20. The double-shaft motor 16 is arranged on the side wall of the bearing plate 14, and the output shaft thereof is connected with one end of the lead screw 17. The other end of the lead screw 17 is rotatably connected with the side wall of the bearing plate 14. One side of the moving plate 18 is slidably connected with the side wall of the bearing plate 14. The lead screw 17 penetrates through the moving plate 18 and is screwed with the moving plate 18. The first electric push rod 19 is arranged on the opposite side wall of the moving plate 18, and the output shaft thereof is connected with the top surface of the clamping plate 20. The control panel 7 is electrically connected with the double-shaft motor 16 and the first electric push rod 19 respectively.

[0026] When the waste is separated to both sides in the separation chamber 9, the waste can be grabbed. First, the electric sliding table 13 drives the bearing plate 14 to the position of the waste, then the double-shaft motor 16 is started to drive the screw rod 17 to rotate, the moving plate 18 converts the rotary motion of the screw rod 17 into linear motion to drive the clamping plate 20 to move in the opposite direction. Under the action of the first electric push rod 19, the clamping plate 20 can be lowered to separately clamp and fix the waste on both sides of the separation chamber 9. After the clamping and fixing are completed, the first electric push rod 19 can be raised, and then under the action of the electric sliding table 13, the waste is transferred to the metal impurity chamber 8 and the pure paraffin chamber 10 respectively. After the clamping plate 20 is controlled to move in the opposite direction, different types of waste can be collected in different positions for classification and treatment.

[0027] Preferably, the grabbing mechanism further comprises a bearing seat 21, which is oppositely arranged on the side wall of the bearing plate 14, and the end of the screw rod 17 away from the double-shaft motor 16 is connected with the bearing seat 21.

[0028] The bearing seat 21 provided can stably rotate the screw rod 17 to ensure that the moving plate 18 can move accurately.

[0029] Preferably, the opposite side walls of the clamping plate 20 are provided with sawteeth 22.

[0030] In order to facilitate the effective collection of waste, the sawteeth 22 are arranged on the side wall of the clamping plate 20. The sawteeth 22 can increase the contact area to accurately grab the waste.

[0031] Preferably, the moving plate 18 comprises a receiving plate 23, an extension plate 24 and a second electric push rod 25. The side wall of the receiving plate 23 is slidably connected with the side wall of the bearing plate 14, the screw rod 17 penetrates through the receiving plate 23 and is screwed with the receiving plate 23, the side of the receiving plate 23 away from the bearing plate 14 is provided with a cavity 26, one side of the extension plate 24 extends into the cavity 26, the second electric push rod 25 is located in the cavity 26, the output shaft of the second electric push rod 25 is connected with the side wall of the extension plate 24, the first electric push rod 19 is arranged on the opposite side wall of the extension plate 24, and the control panel 7 is electrically connected with the second electric push rod 25.

[0032] The length of the moving plate 18 is arranged to be adjustable, so that the clamping plate 20 can be moved to different positions to collect waste at different positions. When the screw rod 17 rotates, the receiving plate 23 is used to convert the rotary motion into linear motion, and the second electric push rod 25 can drive the extension plate 24 to extend and retract in the cavity 26 to adjust the length of the whole moving plate 18, so that the position of the clamping plate 20 at the end of the extension plate 24 changes to realize the clamping of waste at different positions.

[0033] Preferably, the grabbing mechanism further comprises a guide rod 27, which is arranged on the bearing plate 14 and passes through the receiving plate 23.

[0034] The receiving plate 23 can slide along the guide rod 27 when converting the rotary motion of the lead screw 17 into linear motion, and the limiting of the guide rod 27 can avoid the deviation of the receiving plate 23 when moving.

[0035] Preferably, the separating and collecting mechanism further comprises a fan 28, which is embedded on the side wall of the U-shaped partition plate 6 near one side of the metal impurity cavity 8 and faces the other side of the U-shaped partition plate 6, the magnetorheological fluid 11 is located below the fan 28, and the control panel 7 is electrically connected with the fan 28.

[0036] The waste chips without metal impurities float on the liquid magnetorheological fluid 11, and after starting the fan 28, the fan 28 can blow the waste chips without metal impurities to one side of the pure paraffin cavity 10, facilitating the grabbing mechanism to grab the waste chips.

[0037] Preferably, the separating and collecting mechanism further comprises a treatment box 29, a pump body 30, a filter screen 31 and a circulating pipe 32, the treatment box 29 is arranged inside the waste chip groove 3, the pump body 30 is arranged on both sides of the treatment box 29, one end of the circulating pipe 32 is connected with the pump body 30, the other end passes through the U-shaped partition plate 6 and extends into the separating cavity 9, the filter screen 31 is arranged inside the treatment box 29, and the control panel 7 is electrically connected with the pump body 30.

[0038] The magnetorheological fluid 11 will generate some waste materials during long-term use, and part of the waste chips during slicing may be mixed into the magnetorheological fluid 11, so the magnetorheological fluid 11 needs to be cleaned, after starting the pump body 30, the magnetorheological fluid 11 can be pumped into the circulating pipe 32 and enter the treatment box 29, and the filter screen 31 is arranged in the treatment box 29, so that the waste materials and waste chips contained in the magnetorheological fluid 11 can be intercepted by the filter screen 31, and the filtered magnetorheological fluid 11 can re-enter the separating cavity 9 through the circulating pipe 32 on the other side, thereby ensuring the separation effect of the magnetorheological fluid 11 on the metal impurities.

[0040] The magnetorheological fluid 11 can have a reunion effect in long-term use. The electric rotating table 33 and the electromagnet 34 are arranged below the inside of the scrap groove 3. When the magnetorheological fluid 11 enters the treatment box 29, the electromagnet 34 can be controlled to be powered on through the control panel 7. Then the electric rotating table 33 drives the electromagnet 34 to rotate, so that the magnetic field generated by the electromagnet 34 rotates. The magnetic particles in the magnetorheological fluid 11 are subjected to periodic alternating Lorentz force, so that the magnetic particles repeatedly vibrate along the rotation direction of the magnetic field, thereby effectively destroying the reunion chain of the magnetic particles, avoiding the reunion of the magnetorheological fluid 11, and enabling the treated magnetorheological fluid 11 to return to the separation cavity 9, thereby achieving effective separation of the scrap.
