Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a novel small tissue specimen embedding cassette. Background Technology

[0002] In the field of pathological sample processing, novel small tissue embedding cassettes are commonly used to hold tissue samples for dehydration, paraffin infiltration, and other procedures. Traditional small tissue embedding cassettes typically employ a fixed filtration structure, with a single filter size that cannot accommodate samples of varying volumes. When processing small amounts of tissue (such as small samples from puncture biopsies), the sample is prone to leaking out of the filter with the filtrate. During sample collection, the sample must be wrapped in filter paper before being placed into the embedding cassette, a time-consuming process. After tissue dehydration, technicians must then remove the filter paper for embedding, which is both difficult and time-consuming. Using novel small tissue embedding cassettes not only significantly improves the efficiency of physicians and technicians but also enhances safety. Utility Model Content

[0003] Therefore, this utility model provides a novel small tissue specimen embedding cassette, which can effectively improve the work efficiency of pathologists.

[0004] To address the aforementioned problems, this utility model provides a novel small tissue specimen embedding cassette, comprising: a first cassette assembly; a second cassette assembly rotatably mounted on the first cassette assembly, with a receiving space between the second cassette assembly and the first cassette assembly; multiple filter slots disposed on the first and second cassette assemblies, and connected to the receiving space; and a filter assembly detachably mounted in the receiving space, capable of folding or opening with the rotation of the second cassette assembly; wherein, when opened, the filter assembly contains a filter space for placing the sample to be filtered, and the filtered liquid is discharged from the multiple filter slots.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: Through the linkage design of the foldable filter component and the rotating box, an adaptive volume filter space is formed when the filter component is unfolded, which significantly improves the fixation ability of micro-samples; during the filtration process, the sample is confined in the dynamically formed closed space, preventing it from accidentally overflowing from the filter tank with the liquid, while the folding action can help squeeze out residual liquid, ensuring efficient sample retention; this integrated structure is compatible with the processing needs of samples of different sizes, and the filtration mode can be flexibly switched without replacing parts.

[0006] In one embodiment of this utility model, the filter assembly includes: a housing, the housing having at least two opposing surfaces that are respectively attached to a first housing assembly and a second housing assembly; the housing also has a folding side, which can be opened or folded as the second housing assembly rotates.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: the close fit design of the shell and the double-box body ensures the sealing of the filter space edge, preventing sample leakage from the gap between components, and also preventing small samples from flowing out of the filter tank; the characteristic of the folded side opening and closing synchronously with rotation allows the filter components to be compactly stored in the folded state and quickly form a stable chamber in the open state, which optimizes space utilization and avoids sample displacement or loss due to component misalignment during operation, thereby improving filtration reliability.

[0008] In one embodiment of this utility model, the folded side is accordion-shaped.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the accordion-shaped folded side extends through a multi-level pleated structure, dispersing stress during repeated opening and closing, which greatly improves the fatigue resistance and service life of the component; its elastic expansion and contraction characteristics make the change of the filter space volume smoother, avoiding local compression damage to the sample during folding.

[0010] In one embodiment of this utility model, the shell is bonded to the first box assembly and the second box assembly; wherein, the six-point bonding includes: two-point bonding between the shell and the first box assembly and the second box assembly, and two-point bonding at the connection between the shell and the first box assembly and the second box assembly.

[0012] In one embodiment of this utility model, the novel small tissue specimen embedding box further includes a locking component, which is disposed on the first box assembly and the second box assembly; the locking component is used to lock the first box assembly and the second box assembly.

[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: the locking component forcibly fixes the relative positions of the two boxes, eliminating the risk of accidental opening of the boxes due to vibration during transport or centrifugation, and ensuring that the filtration space always remains closed; in the locked state, the filtration component is in a preset pressure environment, further compressing the sample gap and improving the liquid discharge efficiency.

[0014] In one embodiment of this utility model, the locking component further includes: a first locking part disposed on the first housing component; and a second locking part disposed on the second housing component, wherein the first locking part and the second locking part are elastically engaged.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: the elastic interlocking design enables one-click locking / unlocking operations; the interference fit between the protrusion and the interlocking part generates a self-tightening force, which enhances the locking effect as the vibration intensity increases; this mechanical interlocking structure can complete the operation quickly without additional tools, improving process efficiency and safety.

[0016] In one embodiment of this utility model, the second locking part protrudes towards the first locking part; the second locking part is elastically engaged with the first locking part through the protruding portion.

[0017] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by setting a second locking part with a protrusion, it is more convenient to fasten the first locking part and the second locking part. The protrusion can also play a role in positioning and guiding, and the fastening method of the protrusion is also simpler and more convenient.

[0018] In one embodiment of this utility model, the novel small tissue specimen embedding box further includes: a first handle, which is disposed on the second box assembly; and the first handle extends in a direction away from the second locking part.

[0019] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the first buckle hand extension design provides an ergonomic lever to reduce the intensity of unlocking operations; its layout away from the locking part avoids accidental unlocking due to accidental touch, while reserving space for finger operation, making it easy to accurately control the opening and closing angle of the box when wearing gloves.

[0020] In one embodiment of this utility model, the novel small tissue specimen embedding box includes: a first mating part disposed on a first box assembly; a second mating part disposed on a second box assembly, and the second mating part is corresponding to the first mating part; and the first mating part can be embedded in the second mating part to improve the sealing of the edge of the containing space.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: the interlocking embedded parts form a labyrinth seal structure, effectively preventing liquid leakage along the gaps in the box; the improved edge sealing prevents sample fragments from getting stuck in the seams and causing cross-contamination, while also enhancing the structural rigidity of the box when closed, supporting the filter components to withstand higher centrifugal forces.

[0022] In one embodiment of this utility model, the novel small tissue specimen embedding box further includes a second handle, which is disposed on the first box assembly and is offset from the first handle.

[0023] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: the staggered buckle allows for single-handed collaborative operation, with the thumb and forefinger controlling the double buckle to complete the opening, closing and locking actions of the box; the asymmetrical layout clearly defines the operation direction, prevents confusion in the sequence of actions, and improves the smoothness of operation and the human-computer interaction experience of the device.

At the same time, the folding action can help squeeze the residual liquid to ensure efficient sample retention. This integrated structure is compatible with the processing needs of samples of different sizes and can achieve flexible switching of filtration modes without replacing parts. (2) The accordion-shaped folded side extends through a multi-level pleated structure, which disperses stress during repeated opening and closing, greatly improving the fatigue resistance and service life of the component; its elastic expansion and contraction characteristics make the change of the filter space volume smoother, avoiding local compression damage to the sample when folding.
