[0002] Pathological sections are an important sample form in pathological examinations. From the production process, diseased tissues are first obtained from patients, such as through surgical resection, puncture biopsy, etc., and then the tissues are subjected to a series of treatments, including fixation, dehydration, embedding, slicing, etc. Fixation is to use chemical reagents to keep the tissues in their original form; dehydration is to remove the water in the tissues; embedding is to place the tissues in a specific embedding medium; then the embedded tissues are cut into very thin sections, and the above operations are often carried out using a slicing device.

[0003] Existing technologies such as the utility model with the publication number of CN212206637U disclose a slicing device for a pathology department which is convenient to adjust the slicing thickness, including a bottom plate, a blade and a first gear. Support legs are installed at the four corners below the bottom plate, and a main scale plate is arranged above the bottom plate. A vernier slide is arranged on the outer wall of the main scale plate, and a fastening screw is installed on the outer wall of the vernier slide. A cross plate is connected to the inner side of the main scale plate, and a slider is installed on the outer wall of the cross plate. The blade is installed below the slider, and a rotating shaft is arranged inside the blade. An operating table is arranged below the blade, and a control rod is connected below the operating table. The first gear is installed inside the bottom plate, and a second gear is installed on the right side of the first gear. A limiting rod is installed on the upper outer wall of the operating table, and a first spring is installed on the outer wall of the limiting rod. This slicing device can conveniently adjust the thickness of tissue sections, can perform horizontal and vertical cutting, and increases the practicability.

[0004] Currently, most slicing devices often slice pathological tissues through blades, but during the slicing process, the pathological tissues are placed on the blades, resulting in uneven local stress on the sliced pathological tissues, which is likely to cause damage to the pathological tissues and is not conducive to the normal use of the equipment. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages in the existing technologies that most slicing devices often slice pathological tissues through blades, but during the slicing process, the pathological tissues are placed on the blades, resulting in uneven local stress on the sliced pathological tissues, which is likely to cause damage to the pathological tissues, and to propose a slicing device for a pathology department which is convenient to adjust the slicing thickness.

[0006] To achieve the above object, the utility model adopts the following technical solution: A sectioning device for a pathology department that is convenient for adjusting the section thickness, including a bottom plate. The upper surface of the bottom plate is fixedly connected with a support rod, the upper end of the support rod is fixedly connected with a stop block, the lower surface of the bottom plate is fixedly connected with foot pads, and a sectioning mechanism is arranged on the support rod. The sectioning mechanism includes a guide block and a pressing plate. The guide block slides on the surface of the support rod, and the inner wall of the guide block is threadedly connected with a fastening bolt. The pressing plate is located above the bottom plate. The surface of the pressing plate is fixedly connected with a sliding strip, and a sliding groove is formed on the surface of the guide block. The sliding strip slides on the inner wall of the sliding groove. An installation groove is formed at the edge of the pressing plate, and a swing arm is rotatably connected to the inner wall of the installation groove. One end of the swing arm is fixedly connected with a cutting knife. This solution integrates the sectioning device, stably places the pathological section while sectioning, reduces the situation of damage to the pathological section due to uneven force, and facilitates the normal use of the equipment.

[0007] A positioning seat is fixedly connected to the upper surface of the pressing plate, and a cylinder is rotatably connected to the positioning seat. The output end of the cylinder is fixedly connected with a transmission sleeve. A transmission rod is fixedly connected to the side of the swing arm away from the cutting knife. The transmission sleeve is sleeved on the transmission rod. The bottom plate is placed on the operation plane through the foot pads to maintain stability. The support rod plays a supporting role, and the sectioning mechanism is used to perform sectioning operations on pathological samples.

[0008] A pull rod is fixedly connected to the upper surface of the pressing plate, and the edge of the pull rod is rounded. When performing sectioning operations, place the pathological tissue on the bottom plate, then push the pressing plate downward. When the pressing plate abuts against the pathological section, rotate the fastening bolt to tighten it. Then, according to the required section thickness, control the telescopic movement of the cylinder to drive the transmission sleeve to move, thereby enabling the transmission rod to push the swing arm to rotate around the axis of the installation groove, and then the cutting knife rotates.

[0009] The cutting knife is arc-shaped, and the center of the cutting knife and the axis of the swing arm are on the same straight line.

[0010] The number of support rods is four, and the number of guide blocks is two. The two guide blocks are respectively sleeved on two support rods. After adjusting the position of the cutting knife, push the pull rod to one side. The pull rod drives the displacement of the pressing plate. Since the guide rollers can assist the displacement of the pressing plate and are restricted by the sliding strip, the pressing plate drives the horizontal displacement of the cutting knife. Then, the cutting knife slices the pathological tissue, and at the same time, the cut pathological section slides along the arc of the cutting knife to the upper side of the pressing plate. After completing the sectioning operation, pull the pull rod to drive the pressing plate to reset, and then the cut pathological section can be taken. Repeat the above operation to perform continuous sectioning.

[0011] Two symmetrically arranged limiting strips are fixedly connected to the upper surface of the pressing plate, and guide rollers are rotatably connected to the inner wall of the pressing plate. The number of guide rollers is four, and the four guide rollers are arranged at equal intervals.

[0012] A retaining bar is fixedly connected to the upper surfaces of the two guide blocks. The retaining bar is horizontally arranged to facilitate restricting the displacement of the pressing plate.

Subsequently, the cutting knife rotates. After adjusting the position of the cutting knife, push the pull rod to one side. The pull rod drives the displacement of the pressing plate. Since the guide rollers can assist the displacement of the pressing plate and are restricted by the sliding strips, the pressing plate drives the horizontal displacement of the cutting knife. Subsequently, the cutting knife slices the pathological tissue, and at the same time, the cut pathological slice slides along the arc of the cutting knife to the upper side of the pressing plate. After completing the slicing operation, pull the pull rod to drive the pressing plate to reset, and then the cut pathological slice can be taken. Repeating the above operations can perform continuous slicing.

The pressing plate 51 is located above the base plate 1. A slide bar 56 is fixedly connected to the surface of the pressing plate 51. A slide groove 515 is formed on the surface of the guide block 52. The slide bar 56 slides on the inner wall of the slide groove 515. An installation groove 57 is formed at the edge of the pressing plate 51. A swing arm 511 is rotatably connected to the inner wall of the installation groove 57. One end of the swing arm 511 is fixedly connected with a cutting knife 58. This solution integrates the slicing device, stably places the pathological slice during slicing, reduces the situation of damage to the pathological slice due to uneven force, and is convenient for the normal use of the equipment.

[0023] In this embodiment: A positioning seat 513 is fixedly connected to the upper surface of the pressing plate 51. A cylinder 512 is rotatably connected to the positioning seat 513. The output end of the cylinder 512 is fixedly connected with a transmission sleeve 510. A transmission rod 59 is fixedly connected to the side of the swing arm 511 away from the cutting knife 58. The transmission sleeve 510 is sleeved on the transmission rod 59. The base plate 1 is placed on the operation plane through the foot pad 4 to maintain stability.

[0024] Specifically, a pull rod 55 is fixedly connected to the upper surface of the pressing plate 51. The edge of the pull rod 55 is rounded. During the slicing operation, place the pathological tissue on the base plate 1, then push the pressing plate 51 downward. When the pressing plate 51 abuts against the pathological slice, rotate the tightening bolt to tighten it. Then, according to the required slicing thickness, control the telescopic movement of the cylinder 512 to drive the movement of the transmission sleeve 510, so that the transmission rod 59 pushes the swing arm 511 to rotate around the axis of the installation groove 57, and then the cutting knife 58 rotates.

[0025] Specifically, the cutting knife 58 is arc-shaped, and the center of the cutting knife 58 and the axis of the swing arm 511 are on the same straight line.

[0026] In this embodiment: There are four support rods 2 and two guide blocks 52. The two guide blocks 52 are respectively sleeved on the two support rods 2. After adjusting the position of the cutting knife 58, push the pull rod 55 to one side. The pull rod 55 drives the pressing plate 51 to displace. Since the guide roller 54 can assist the displacement of the pressing plate 51 and is restricted by the slide bar 56, the pressing plate 51 drives the cutting knife 58 to displace horizontally. Subsequently, the cutting knife 58 slices the pathological tissue.

[0029] Working principle: The bottom plate 1 is placed on the operating plane through the foot pads 4 to maintain stability. The support rod 2 plays a supporting role. The slicing mechanism 5 is used to slice the pathological sample. When performing the slicing operation, place the pathological tissue on the bottom plate 1. Then, push the pressing plate 51 downward. When the pressing plate 51 abuts against the pathological section, rotate the fastening bolt and tighten it. Then, according to the required thickness of the slice, control the telescopic movement of the air cylinder 512 to drive the transmission sleeve 510 to move, so that the transmission rod 59 pushes the swing arm 511 to rotate around the axis of the mounting groove 57. Subsequently, the cutting knife 58 rotates. After adjusting the position of the cutting knife 58, push the pull rod 55 to one side. The pull rod 55 drives the pressing plate 51 to displace. Since the guide roller 54 can assist the displacement of the pressing plate 51 and is restricted by the slide bar 56, the pressing plate 51 drives the cutting knife 58 to displace horizontally. Subsequently, the cutting knife 58 slices the pathological tissue. At the same time, the cut pathological section slides along the arc of the cutting knife 58 to the upper side of the pressing plate 51. After completing the slicing operation, pull the pull rod 55 to drive the pressing plate 51 to reset. Then, the cut pathological section can be taken. Repeating the above operations can perform continuous slicing. This solution integrates the slicing device, stably places the pathological section during slicing, reduces the situation of damage to the pathological section due to uneven force, and facilitates the normal use of the equipment.
