A frozen section sample holder

Technical Field

The utility model relates to the technical field of frozen sectioning, in particular to a frozen sectioning sample tray.

Background Art

"Frozen section" usually refers to the process of freezing samples (such as tissues, cells, etc.) at extremely low temperatures and then preparing slices using a microtome or other tools. This technology is often used in fields such as pathology and neuroscience to analyze and observe samples. Frozen sectioning can produce high-quality slices and retain certain special structures of the sample, while avoiding problems such as denaturation that may be caused by heat treatment.

For example, the Chinese patent with the publication number CN219027682U discloses a frozen section sample holder, including an outer disc and an inner disc, the upper sides of the outer disc and the inner disc are both provided with annular protrusions, and the outer side of the bottom of the outer disc is provided with a buckle groove; the middle of the outer disc is through, and the inner disc is placed in the middle of the outer disc for sliding cooperation; four groups of slide grooves are provided on the inner wall of the outer disc, and four groups of fixed columns are provided on the outer wall of the inner disc, and the fixed columns can slide and cooperate in the slide grooves; the slide groove is composed of an introduction part, a fixed part, and a sliding part, and grooves are provided at the top of the fixed part and the top of the sliding part, and a side plate extends downward on the right side of the groove of the fixed part; the introduction part and the fixed part are on the same axis, and a notch is provided at the connection between the introduction part and the fixed part, and the lower end of the sliding part is connected to the notch; the inner disc is a cylinder with an opening at the bottom, and two groups of inner and outer springs are provided in the inner disc. The utility model adopts a manual rotation lifting structure, so that the inner disc can be lifted, and when the next section is sliced, there is no need to raise the frozen section sample holder, which is more convenient.

DETAILED DESCRIPTION

In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

As shown in Figure 1, a frozen section sample tray includes a base 1, the top of the base 1 is fixedly connected to a lifting mechanism 2, the outer surface of the lifting mechanism 2 is movably connected to a steering mechanism 3, the top of the steering mechanism 3 is rotatably connected to a tray 4, and the top of the tray 4 is overlapped with a frozen section sample 5.

It should be noted that, through the provided lifting mechanism 2, the tray 4 can be driven to move upward, thereby raising the frozen section sample 5, so that the slicing operation will not be overly affected by the instrument. At the same time, the manual rotation method is adopted, which makes the lifting and lowering simple and can also control the distance well. Through the provided steering mechanism 3, in conjunction with multiple card holes 33, the frozen section sample 5 can be adjusted to the most suitable observation angle, so that the observation is faster, thereby achieving better processing results.

As shown in Figures 4 and 5, the lifting mechanism 2 includes a fixed sleeve 21, the bottom of the fixed sleeve 21 is fixedly connected to the top of the base 1, a threaded rod 24 is rotatably connected to the middle of the top of the base 1, the lower end of the outer surface of the threaded rod 24 is fixedly connected to a bevel gear 26, the right end of the outer surface of the bevel gear 26 is meshed with a bevel gear 1 25, the right side surface of the bevel gear 1 25 is fixedly connected to a rotating shaft 20, and the right end of the rotating shaft 20 passes through the right side of the fixed sleeve 21 and is fixedly connected to a rotating rod 22.

It should be noted that by rotating the rotating rod 22 clockwise, the rotating shaft 20 rotates clockwise, thereby driving the bevel gear 1 25 to rotate clockwise. Since the bevel gear 1 25 and the bevel gear 2 26 are meshed with each other, the bevel gear 2 26 rotates counterclockwise, thereby driving the threaded rod 24 to rotate counterclockwise. Since the threaded rod 24 and the threaded plate 39 are threadedly connected to each other, the threaded plate 39 moves upward. Square grooves 23 are provided on the front and rear sides of the fixed sleeve 21, and the threaded plate 39 moves inside it, thereby making the movement smoother, thereby driving the lifting sleeve 31 to move upward. A slide groove 38 is provided on the right side of the lifting sleeve 31. Under the action of the slide groove 38, the lifting sleeve 31 can rise smoothly without affecting the rotation of the rotating rod 22, thereby driving the tray 4 to move upward, thereby raising the frozen section sample 5, so that the slicing operation will not be affected too much by the instrument and becomes simpler.

As shown in Figures 2 to 5, the steering mechanism 3 includes a lifting sleeve 31, the inner wall of the lifting sleeve 31 is movably connected to the outer surface of the fixed sleeve 21, the top of the lifting sleeve 31 is rotatably connected to the bottom of the tray 4, the upper end of the outer surface of the lifting sleeve 31 is fixedly connected to a circular plate 32, the left end of the circular plate 32 is movably connected to a sliding rod 35, the upper end of the outer surface of the sliding rod 35 is movably connected to a spring 36, the upper end of the outer surface of the sliding rod 35 is fixedly connected to a baffle 37, the baffle 37 is located above the spring 36, the outer surface of the threaded rod 24 is threadedly connected to a threaded plate 39, and the front and rear sides of the threaded plate 39 are fixedly connected to the lower end of the inner wall of the lifting sleeve 31.

The anti-slip strip 34 is pulled downward to allow the slide bar 35 to move downward and disengage from the locking hole 33. The anti-slip strip 34 is made of rubber and has good anti-slip properties, so that the slide bar 35 will not slip out of the hand easily, and will drive the baffle plate 37 to move downward, thereby compressing the spring 36, and then the tray 4 is rotated to make the frozen section sample 5 reach a suitable observation angle. A plurality of locking holes 33 are provided under the tray 4. The suitable locking holes 33 are aligned with the slide bar 35, and then the anti-slip strip 34 is released. Under the action of the spring 36, the slide bar 35 slides into the locking hole 33. The upper end of the slide bar 35 is hemispherical, which can be more easily inserted into the inside of the locking hole 33. Under the limitation of the baffle plate 37, the anti-slip strip 34 will not contact the circular plate 32 and be damaged, thereby fixing the tray 4 to achieve the effect of adjusting the observation angle of the frozen section sample 5.

As shown in FIG. 4 and FIG. 5 , a slide groove 38 is provided at the lower end of the right side of the lifting sleeve 31 , and the width of the slide groove 38 is slightly larger than the diameter of the outer surface of the rotating shaft 20 .

It should be noted that a slide groove 38 is provided on the right side of the lifting sleeve 31 , and under the action of the slide groove 38 , the lifting sleeve 31 can be smoothly raised without affecting the rotation of the rotating rod 22 .

As shown in FIG. 4 and FIG. 5 , square grooves 23 are formed on both sides of the front side of the fixing sleeve 21 , and the width of the square grooves 23 is consistent with the width of the threaded plate 39 .

It should be noted that square grooves 23 are provided on the front and rear sides of the fixing sleeve 21, and the threaded plate 39 moves inside the square grooves 23, thereby making the movement more stable.

As shown in FIG. 2 and FIG. 3 , the lower end of the outer surface of the slide bar 35 is fixedly connected with an anti-slip strip 34 , and the upper end of the slide bar 35 is in a hemispherical shape.

It should be noted that the anti-slip strip 34 is made of rubber and has excellent anti-slip properties, so that the slide bar 35 will not slip out easily. The upper end of the slide bar 35 is hemispherical and can be more easily inserted into the inside of the card hole 33.

As shown in FIG. 2 , a plurality of locking holes 33 are formed in a circular array at the bottom of the tray 4 , and the inner wall diameters of the locking holes 33 are consistent with the outer surface diameter of the slide rod 35 .

It should be noted that a plurality of locking holes 33 are provided below the tray 4 , and the slide bars 35 slide into the locking holes 33 to fix the tray 4 .

As shown in FIG. 2 and FIG. 3 , the diameter of the outer surface of the baffle 37 is much larger than the inner wall diameter of the clamping hole 33 , and the outer surface diameter of the baffle 37 is slightly larger than the outer ring diameter of the spring 36 .

It should be noted that the baffle 37 not only compresses the spring 36 smoothly, but also plays a certain limiting role, so that the anti-slip strip 34 will not contact the circular plate 32 and be damaged.

The working principle of the utility model is as follows: by rotating the rotating rod 22 clockwise, the rotating shaft 20 rotates clockwise, thereby driving the bevel gear 1 25 to rotate clockwise. Since the bevel gear 1 25 and the bevel gear 2 26 are meshed with each other, the bevel gear 2 26 rotates counterclockwise, thereby driving the threaded rod 24 to rotate counterclockwise. Since the threaded rod 24 and the threaded plate 39 are threadedly connected to each other, the threaded plate 39 moves upward. Square grooves 23 are provided on the front and rear sides of the fixed sleeve 21, and the threaded plate 39 moves inside it, thereby making the movement more stable, thereby driving the lifting sleeve 31 to move upward. A sliding groove 38 is provided on the right side of the lifting sleeve 31. Under the action of the sliding groove 38, the lifting sleeve 31 can rise smoothly without affecting the rotation of the rotating rod 22, thereby driving the tray 4 to move upward, thereby raising the frozen section sample 5, so that the slicing operation will not be affected. The anti-slip strip 34 is made of rubber and has good anti-slip properties, so that the slide bar 35 will not slip out of the hand easily, and then it will drive the baffle plate 37 to move downward, thereby compressing the spring 36, and then the tray 4 is rotated to make the frozen section sample 5 reach a suitable observation angle. A plurality of clamping holes 33 are provided under the tray 4, and the suitable clamping holes 33 are aligned with the slide bar 35, and then the anti-slip strip 34 is released, and under the action of the spring 36, the slide bar 35 slides into the clamping hole 33. The upper end of the slide bar 35 is hemispherical, which can be more easily clamped into the inside of the clamping hole 33. Under the limitation of the baffle plate 37, the anti-slip strip 34 will not contact the circular plate 32 and be damaged, thereby fixing the tray 4, so as to achieve the effect of adjusting the observation angle of the frozen section sample 5.
