Description

Technical Field

[0001] This invention relates to the field of medical and life science experimental instruments, and in particular to a fully automatic slicer for embedded slice processing. Background Technology

[0002] In the fields of medicine, biology, and life sciences, microtome is often used to prepare tissue sections from samples for easier observation. Microtome is mainly used in two areas: firstly, for ultrathin sections of embedded paraffin and frozen tissues, which are then used for morphological studies; and secondly, for sectioning fresh biological tissues.

[0003] Currently, the automation level of embedded microtome machines on the market is low, with most being manual or semi-automatic. They are not only structurally complex but also cumbersome to operate and inefficient. Furthermore, existing embedded microtome machines use a DC servo motor and rack and pinion gears to control the Z-axis cutting speed, resulting in low cutting speed control precision. Moreover, prolonged engagement of the rack and pinion gears leads to wear, affecting control accuracy and generating significant noise. Summary of the Invention

[0004] Based on this, the present invention provides a fully automatic microtome for embedded sectioning, aiming to solve the problems of low automation levels in existing embedded sectioning machines on the market, most of which are manual or semi-automatic, not only with complex structures but also cumbersome operation and low efficiency. Furthermore, existing embedded sectioning machines use a DC servo motor and rack and pinion gears to achieve linear movement and control the slicing speed in the Z-axis cutting direction. This results in low cutting speed control accuracy, and the rack and pinion gears wear out over time, affecting control accuracy and generating significant noise.

[0005] To achieve the above objectives, the present invention proposes the following technical solution:

[0006] A fully automatic slicer for embedding sectioning includes a base plate, a support plate, an X-axis assembly, a Y-axis assembly, a Z-axis assembly, an embedding axis assembly, a bath, a housing, and a microelectronic control chip. The support plate, the X-axis assembly, and the bath are all mounted on the base plate. The Z-axis assembly is mounted on the support plate. The Y-axis assembly is mounted on the Z-axis assembly. The embedding axis assembly is located inside the bath. The housing covers the X-axis assembly and is mounted on the base plate. The output end of the X-axis assembly extends out of the housing and connects to the embedding axis assembly. The Y-axis assembly is positioned opposite the bath. The microelectronic control chip is located inside the housing. The X-axis assembly, Y-axis assembly, and Z-axis assembly are all electrically connected to the microelectronic control chip.

[0007] In the use of the fully automatic microtome of this application, tissue culture medium is first added to the bath, and then the tissue to be sliced ​​is adhered to the end face of the embedding axis assembly away from the X-axis assembly, and the embedding axis assembly is installed in the bath; next, one end of the embedding axis assembly is connected to the X-axis assembly, and the tissue to be sliced ​​adhered to the embedding axis assembly is adjusted to be directly below the Y-axis assembly, so as to facilitate slicing by the blade mounted on the Y-axis assembly; during the slicing process, the microelectronic control chip controls the linkage between the X-axis assembly, the Y-axis assembly and the Z-axis assembly under a preset program to complete the tissue slicing.

[0008] Further, the Y-axis assembly includes a Y-axis fixing plate, a Y-axis motor, an eccentric wheel, a connecting strip, a connecting plate, a Y-axis slider, a Y-axis slide rail, and a blade fixing shaft; the Y-axis fixing plate is disposed on the Z-axis assembly; the Y-axis motor is disposed on one side of the Y-axis fixing plate; the output end of the Y-axis motor passes through the Y-axis fixing plate and is connected to the eccentric wheel; one end of the connecting strip is connected to the eccentric wheel, and the other end is connected to the connecting plate; the Y-axis slide rail is disposed on the side of the Y-axis fixing plate away from the Y-axis motor; one side of the Y-axis slider is connected to the connecting plate, and the other side is slidably connected to the Y-axis slide rail; the blade fixing shaft is disposed at the bottom of the connecting plate.

[0009] Further, the X-axis assembly includes an X-axis fixing plate, an X-axis motor, an X-axis lead screw, an X-axis moving stage, a propulsion shaft fixing block, a propulsion shaft, and a connector; the X-axis fixing plate has a first X-axis protrusion and a second X-axis protrusion at both ends; the X-axis fixing plate is mounted on the support plate; the X-axis motor is mounted on the side of the first X-axis protrusion away from the second X-axis protrusion; one end of the X-axis lead screw passes through the first X-axis protrusion and is connected to the output end of the X-axis motor, and the other end of the X-axis lead screw passes through the X-axis moving stage and is rotatably mounted on the second X-axis protrusion; the propulsion shaft fixing block is mounted on the X-axis moving stage; one end of the propulsion shaft is mounted on the propulsion shaft fixing block, and the other end is connected to the connector; the end of the connector away from the propulsion shaft is connected to the embedding shaft assembly.

[0010] Furthermore, the X-axis motor is a stepper motor.

[0011] Furthermore, the Z-axis assembly includes a Z-axis fixing plate, a Z-axis motor, and a Z-axis lead screw; the two ends of the Z-axis fixing plate are respectively provided with a first Z-axis protrusion and a second Z-axis protrusion; the Z-axis fixing plate is disposed on the support plate; the Z-axis motor is disposed on the side of the first Z-axis protrusion away from the second Z-axis protrusion; one end of the Z-axis lead screw passes through the first Z-axis protrusion and is connected to the output end of the Z-axis motor, and the other end of the Z-axis lead screw passes through the Y-axis fixing plate and is rotatably disposed on the second Z-axis protrusion.

[0012] Furthermore, the Z-axis motor is a stepper motor.

[0013] Furthermore, the embedded shaft assembly includes an embedded shaft fixing frame, a bushing, a movable shaft, and a retaining ring; the embedded shaft fixing frame is disposed inside the bathtub; the bushing is disposed on the embedded shaft fixing frame; one end of the movable shaft is connected to the connector, and the other end is adapted to the bushing; the retaining ring is disposed at the end of the bushing to limit the axial movement of the bushing and prevent the bushing from moving axially under the drive of the movable shaft.

[0014] Furthermore, the bottom of the embedded shaft fixing bracket is provided with multiple positioning protrusions.

[0015] Furthermore, the bathtub has a "T" shaped structure; the bottom of the bathtub is provided with a positioning groove that matches the positioning protrusion.

[0016] In this application, the positioning groove and the positioning protrusion are adapted to facilitate the quick and accurate installation of the embedding shaft holder into the bath, while also providing a certain degree of error prevention. The bath is designed with a "T"-shaped structure, which facilitates the placement of the embedding shaft assembly with the tissue to be sectioned into the bath. Compared to existing baths that require openings to place the embedding shaft, this effectively prevents the culture medium from seeping out of the bath, avoiding waste of the culture medium, and also maintains the cleanliness of the microtome during sectioning.

[0017] Furthermore, the outer casing is also equipped with an LCD display screen electrically connected to the microelectronic control chip and multiple adjustment buttons; the LCD display screen can display various parameters and statuses of the slicer in real time during the operation of the slicer, so that the operator can quickly understand the various indicators of the slicer and the various operating statuses of the slicing process, and can change the operating status of the slicer through the adjustment buttons.

[0018] In this application, stepper motors are used on the X and Z axes. Compared with the existing slicing machines that use gears and racks, stepper motors have the characteristics of high precision, low noise and stable operation, which significantly improves the controllability of the slicing machine, thereby improving the slicing precision and slicing quality.

[0019] This invention proposes a fully automatic microtome for embedded sectioning. It utilizes a microelectronic control chip to control the interconnectedness of various components to complete the slicing action, achieving a high degree of automation. By employing stepper motors and lead screws in the X and Z axes for transmission, compared to traditional gear and rack transmissions, this invention's structure allows for more precise control of the cutting thickness and speed, offering high controllability. Furthermore, this structure exhibits low operating noise and stable operation. The "T"-shaped design of the culture bath effectively prevents the culture medium from seeping out, ensuring the cleanliness of the microtome during slicing and effectively avoiding culture medium waste. The connection between the microelectronic control chip and an LCD display allows operators to quickly understand the microtome's various indicators and operational statuses, and adjust parameters based on this information, achieving a combined control and display effect. This invention is simple in structure, convenient to operate, and economical. Attached Figure Description

If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0033] Currently, most embedded microtome machines on the market have low levels of automation, being either manual or semi-automatic. They are not only structurally complex but also cumbersome to operate and inefficient. Furthermore, existing embedded microtome machines use a DC servo motor and rack and pinion gears to control the Z-axis cutting speed, resulting in low cutting speed control precision. Prolonged engagement of the rack and pinion gears leads to wear, affecting control accuracy and generating significant noise. To address these technical problems, this invention proposes a fully automatic microtome for embedded microtome processing.

[0035] In the use of the fully automatic microtome in this embodiment, tissue culture medium is first added to the bath 7. Then, the tissue to be sliced ​​is adhered to the end face of the embedding shaft assembly 6 away from the X-axis assembly 3, and the embedding shaft assembly 6 is installed in the bath 7. Next, one end of the embedding shaft assembly 6 is connected to the X-axis assembly 3, and the tissue to be sliced ​​adhered to the embedding shaft assembly 6 is adjusted to be directly below the Y-axis assembly 4, so that the blade mounted on the Y-axis assembly 4 can slice the tissue. During the slicing process, the microelectronic control chip controls the linkage between the X-axis assembly 3, the Y-axis assembly 4 and the Z-axis assembly 5 under a preset program to complete the tissue slicing.

[0036] Reference Figure 3In this embodiment, the Y-axis assembly 4 includes a Y-axis fixing plate 41, a Y-axis motor 42, an eccentric wheel 43, a connecting bar 44, a connecting plate 45, a Y-axis slider 46, a Y-axis slide rail 47, and a blade fixing shaft 48. The Y-axis fixing plate 41 is disposed on the Z-axis assembly 5. The Y-axis motor 42 is disposed on one side of the Y-axis fixing plate 41. The output end of the Y-axis motor 42 passes through the Y-axis fixing plate 41 and is connected to the eccentric wheel 43. One end of the connecting bar 44 is connected to the eccentric wheel 43, and the other end is connected to the connecting plate 45. The Y-axis slide rail 47 is disposed on the side of the Y-axis fixing plate 41 away from the Y-axis motor 42. One side of the Y-axis slider 46 is connected to the connecting plate 45, and the other side is slidably connected to the Y-axis slide rail 47. The blade fixing shaft 48 is disposed at the bottom of the connecting plate 45.

[0037] In this embodiment, the Y-axis motor 42 is a miniature DC servo motor, and the eccentric distance of the eccentric wheel 43 is 1mm. The two work together to drive the blade on the blade fixing shaft 48 to move left and right, thereby realizing the "cutting" action when slicing, and the "cutting" range reaches 2mm to ensure that the sliced ​​tissue sections achieve the best results.

[0038] Reference Figure 4 In this embodiment, the X-axis assembly 3 includes an X-axis fixing plate 31, an X-axis motor 32, an X-axis lead screw 33, an X-axis moving stage 34, a feed shaft fixing block 35, a feed shaft 36, and a connector 37; the X-axis fixing plate 31 has a first X-axis protrusion 311 and a second X-axis protrusion 312 at its two ends; the X-axis fixing plate 31 is mounted on the support plate 2; the X-axis motor 32 is located on the side of the first X-axis protrusion 311 away from the second X-axis protrusion 312; the X-axis lead screw 33... One end of the rod 33 passes through the first X-axis protrusion 311 and is connected to the output end of the X-axis motor 32. The other end of the X-axis lead screw 33 passes through the X-axis moving stage 34 and is rotatably mounted on the second X-axis protrusion 123. The push shaft fixing block 35 is mounted on the X-axis moving stage 34. One end of the push shaft 36 is mounted on the push shaft fixing block 35, and the other end is connected to the connector 37. The end of the connector 37 away from the push shaft 36 is connected to the embedded shaft assembly 6.

[0039] The X-axis motor 32 is a stepper motor.

[0040] Refer again Figure 3In this embodiment, the Z-axis assembly 5 includes a Z-axis fixing plate 51, a Z-axis motor 52, and a Z-axis lead screw 53. The Z-axis fixing plate 51 has a first Z-axis protrusion 511 and a second Z-axis protrusion 512 at its two ends. The Z-axis fixing plate 51 is mounted on the support plate 2. The Z-axis motor 52 is mounted on the side of the first Z-axis protrusion 511 away from the second Z-axis protrusion 512. One end of the Z-axis lead screw 53 passes through the first Z-axis protrusion 511 and is connected to the output end of the Z-axis motor 52. The other end of the Z-axis lead screw 53 passes through the Y-axis fixing plate 41 and is rotatably mounted on the second Z-axis protrusion 512.

[0041] The Z-axis motor 52 is a stepper motor.

[0042] Reference Figure 5 and Figure 6 In this embodiment, the embedded shaft assembly 6 includes an embedded shaft fixing frame 61, a bushing 62, a movable shaft 63, and a retaining ring 64; the embedded shaft fixing frame 61 is disposed inside the bathtub 7; the bushing 62 is disposed on the embedded shaft fixing frame 61; one end of the movable shaft 63 is connected to the connector 37, and the other end is adapted to the bushing 62; the retaining ring 64 is disposed at the end of the bushing 62 to limit the axial movement of the bushing 62 and prevent the bushing 62 from moving axially under the drive of the movable shaft 63.

[0043] In this embodiment, one end of the moving shaft 63 passes through the bushing 62, and the other end is connected to the connector 37, allowing the moving shaft 63 to move synchronously with the connector 37 and, under the limiting effect of the bushing 62, to move only along the axial direction of the bushing 62. The tissue to be sliced ​​is adhered to the end face of the moving shaft 63 away from the connector 37 using tissue adhesive. The movement of the moving shaft 63 is then controlled by controlling the forward and reverse rotation of the X-axis motor 32, thereby cooperating with other components to realize the slicing process of the microtome and adjusting the thickness of the tissue slices. In this embodiment, the tissue adhesive can be 502.

[0044] The bottom of the embedded shaft fixing bracket 61 is provided with multiple positioning grooves (not shown in the figure).

[0045] The bathtub 7 has a "T" shaped structure; the bottom of the bathtub 7 is provided with a positioning protrusion 71 that matches the positioning groove.

[0046] In this embodiment, the positioning groove and the positioning protrusion 71 are adapted to each other, which facilitates the operator to quickly and accurately install the embedding shaft fixing bracket 61 into the bath 7, and also plays a certain role in preventing mistakes. The bath 7 is designed with a "T" shape, which makes it easy to put the embedding shaft assembly 6 with the tissue to be sectioned into the bath 7. Compared with the existing baths that require openings to place the embedding shaft, this can effectively prevent the culture medium in the bath 7 from seeping out, avoid the waste of culture medium, and also maintain the cleanliness of the microtome during sectioning.

[0047] Refer again Figure 1 In this embodiment of the application, the outer casing 8 is also provided with an LCD display screen 81 electrically connected to the microelectronic control chip and a plurality of adjustment buttons 82; the LCD display screen 81 can display various parameters and statuses of the slicer in real time, so that the operator can quickly understand the various indicators of the slicer and the various operating statuses of the slicing process, and can change the operating status of the slicer through the adjustment buttons 82.

[0048] In this embodiment, stepper motors are used on the X and Z axes. Compared with the existing slicing machines that use gears and racks, stepper motors have the characteristics of high precision, low noise and stable operation, which significantly improves the controllability of the slicing machine, thereby improving the slicing precision and slicing quality.

[0049] In this embodiment, the microelectronic control chip is a small but complete microcomputer system that integrates a central processing unit (CPU) with data processing capabilities, random access memory (RAM), read-only memory (ROM), multiple I / O ports, an interrupt system, timers / counters, and other functions, as well as display driver circuits, pulse width modulation circuits, analog multiplexers, and A / D converters, all on a single chip using very large-scale integrated circuit technology. This allows the slicer of this application to perform slicing processing and set various parameters with only a few adjustment buttons. The microelectronic control chip controls the stepper motor amplifiers of the X and Y axes, which then drive the stepper motors to perform forward and reverse rotation for slicing. The processing speed and cutting thickness can be displayed on the LCD display screen 81 driven by the microelectronic control chip, and the slicing speed and thickness can also be adjusted using the adjustment buttons 82 on the outer casing 8.

[0050] In this embodiment, the Y-axis motor 42 is controlled by the PWM module of the microelectronic control chip for speed regulation, and the X-axis motor 32 and the Z-axis motor 52 are controlled by stepper motors. The stepper motor drives the lead screw to rotate, and the lead screw advances 1mm for each rotation. Since each pulse moves 1.8°, 200 pulses are needed to advance 1mm on the X-axis and Z-axis. In this embodiment, the stepper motor driver is subdivided into four parts, so 800 pulses are needed to advance 1mm. The control resolution is 1mm / 800 = 0.00125mm (1.25um), which means the minimum slice thickness of the slicer is 1.25um.

[0051] This invention discloses a fully automatic microtome for embedded sectioning, which uses a microelectronic control chip to control the interconnection of various components to complete the slicing action, achieving a high degree of automation. By using stepper motors and lead screws for transmission in the X and Z axes, compared to the original gear and rack transmission, the structure of this application can more precisely control the cutting thickness and cutting speed of the microtome, offering high controllability. Furthermore, the structure of this application operates with low noise and stable performance. By designing the bath 7 into a "T" shape, the culture medium inside the bath can be effectively prevented from seeping out, ensuring the cleanliness of the microtome during slicing and effectively avoiding waste of the culture medium. The connection between the microelectronic control chip and the LCD display 81 allows the operator to quickly understand the various indicators and operating states of the microtome, and adjust the parameters of the microtome based on the obtained information, achieving a combination of control and display. This invention is simple in structure, convenient to operate, and economical.
