Abstract
Description
DEVICE FOR IMMOBILIZING TISSUE SPECIMEN OR TISSUE SPECIMENS FOR AUTOMATED EMBEDDERFIELD
[0001] The present disclosure relates to a field of histological tissue grossing, processing and embedding, and more particularly to a device for immobilizing a tissue specimen or a plurality of tissue specimens for an automated embedder.BACKGROUND
[0002] Embedding of tissue specimens is predominantly performed by manual operation. Generally, a technician opens a routine cassette for containing a tissue specimen during grossing and processing of the tissue specimen, picks the tissue specimen out of the routine cassette, properly orientates it into an embedding mold, fills the embedding mold with paraffin, and allow a block embedding the tissue specimen to be formed by cooling. The manual embedding is time-consuming and introduces risk factors, e.g., tissue loss, orientation mistake, and cross contamination.
[0003] In related art, a sectionable cassette is known which uses detent structures to sandwich the tissue specimen between a cover and a base of the sectional cassette. Thus, the sectional cassette may be used during embedding of the tissue specimen. However, the sectional cassette is not a satisfactory technical solution, because the tissue specimen will shrink and has a space for movement after tissue processing, and an irregular tissue specimen or multiple tissue specimens with different sizes cannot be immobilized on the same plane.SUMMARY
[0004] Embodiments of the present disclosure seek to solve at least one of the problems existing in the related art to at least some extent.
[0005] To this end, embodiments of the present disclosure provide a device for immobilizing a tissue specimen or a plurality of tissue specimens for an automated embedder which may orientate and secure one or more tissue specimens of a wide variety of types, shapes and sizes, and prevent the one or more tissue specimens from being lost during grossing, processing and embedding.
[0006] According to embodiments of the present disclosure, a device for immobilizing a tissue specimen or a plurality of tissue specimens for an automated embedder is provided. The device includes a base, a cover and a frame. The base has a cavity configured to accommodate the tissue specimen or the plurality of tissue specimens. The cover is coupled to the base and has an orientation structure configured to orientate and secure the tissue specimen or the plurality of tissue specimens in the cavity of the base. The base and the cover are detachably coupled to the frame. The orientation structure includes a plurality of elastic ribs configured to provide a pressure on the tissue specimen or the plurality of tissue specimens and adjust the pressure according to a height of the tissue specimen or heights of the plurality of tissue specimens; and a flexible sheet coupled to the plurality of elastic ribs and having a plurality of flexible portions configured to contact and wrap the tissue specimen or the plurality of tissue specimens independently.
[0007] In the device for immobilizing a tissue specimen or a plurality of tissue specimens for an automated embedder, the orientation structure includes the plurality of elastic ribs, and the flexible sheet coupled to the plurality of elastic ribs. Thus, the tissue specimen or the plurality of tissue specimens may be pre-orientated, the manual embedding may be bypassed to allow embedding automation, and the device may secure the orientation of the tissue specimen or the plurality of tissue specimens from grossing to sectioning. The flexible sheet has a plurality of flexible portions configured to contact and wrap the tissue specimen or the plurality of tissue specimens independently. Thus, the device is suitable for immobilizing a wide variety of types, shapes and sizes of the tissue specimen or the plurality of tissue specimens on the same plane.
[0008] In some embodiments, each of the plurality of flexible portions includes a waveform structure for coupling two adjacent elastic ribs of the plurality of elastic ribs. Thus, the elastic ribs coupled to the waveform structure may adjust the pressure on the tissue specimen or the plurality of tissue specimens independently.
[0009] In some embodiments, the waveform structure has a thickness of 0.3-0.5mm, a width of 0.4-1mm and a length of 4-7mm. The size of the waveform structure has influence on the independence between the elastic ribs coupled to the waveform. The waveform structure having the size within the above scope may provide good independence between the elastic ribs coupled to the waveform structure, and reduce a pressure acting on the tissue sample to avoid crushing and cracking of the tissue sample due to excessive stress, which in turn affects the observation of the section of the tissue sample under the microscope. Moreover, the waveform structure may fit better on the tissue sample and wrap around the tissue sample, to render the tissue sample to abut against the base tightly, which facilitates a doctor to better cut out a complete surface of the tissue sample after the tissue sample is embedded to form a wax block.
[0010] In some embodiments, each of the plurality of flexible portions includes a plurality of waveform structures coupled end to end. Thus, more elastic ribs coupled to the same flexible portion may be independent from each other.
[0011] In some embodiments, the plurality of elastic ribs includes a first type rib and a second type rib, and the first type rib is greater than the second type rib in length. The longer first type rib may avoid crushing or fracturing of the tissue specimen or the plurality of tissue specimens, and the shorter second type rib may ensure that the tissue specimen or the plurality of tissue specimens will not be lost.
[0012] In some embodiments, each of the plurality of elastic ribs has a thickness of 0.3-0.5mm and a width of 0.4-1mm. The thickness and the width of elastic ribs may have influence on a force for immobilizing the uneven tissue specimen or the plurality of tissue specimens of different heights. The elastic ribs having the size within the above scope may provide proper force for immobilizing the uneven tissue specimen or the plurality of tissue specimens of different heights.
[0013] In some embodiments, the first type rib is L-shaped, and the second type rib is S-shaped. The L-shape first type rib may provide a smaller pressure on the tissue specimen or the plurality of tissue specimens than the S-shaped second type rib. The S-shape prevents the second type rib from exceeding an upper surface of the cover when the device of the present disclosure presses tissue samples having a thickness of 4 millimeters, which in turn results in an increase in a height of the device of the present disclosure and a reduction in the number of the device of the present disclosure that may be placed in a dehydration basket. Moreover, the S-shape increases the length of the second type rib, which increases a force arm and thereby reduces a pressure acting on the tissue sample.
[0014] In some embodiments, the elastic ribs coupled to each flexible portion are arranged in a staggered manner along an extending direction of the flexible portion. Thus, uniform stress on the tissue specimen or the plurality of tissue specimens may be ensured.
[0015] In some embodiments, each of the plurality of flexible portions is coupled to four to six elastic ribs. Thus, the tissue specimen or the plurality of tissue specimens may well fit to the base.
[0016] In some embodiments, the plurality of flexible portions is arranged in parallel. Thus, the tissue specimen or the plurality of tissue specimens may be well wrapped by the flexible sheet.
[0017] In some embodiments, the cover further includes a safety wall arranged on the flexible sheet and configured to avoid loss or cross contamination of the tissue specimen or the plurality of tissue specimens. Thus, the tissue specimen or the plurality of tissue specimens may be prevented from loss or cross contamination.
[0018] In some embodiments, the cover further includes a retaining wall having an outer peripheral face matching an inner peripheral face of the base. Thus the strength of the cover may be enhanced, and the position of the cover may be limited when the cover is inserted into the base.
[0019] In some embodiments, the cover is rotatably coupled to the base through a hinge. Thus, the cover and the base are coupled as an integrated component.
[0020] In some embodiments, the cover further includes a cover body detachably coupled to the base, and the flexible sheet is coupled to cover body through the plurality of elastic ribs. Thus, the cover body may support the elastic ribs and the flexible sheet, to form into one piece.
[0021] In some embodiments, the cover body defines an opening extending through the cover body in a thickness direction of the cover body, and the flexible sheet is located within the opening when viewed along the thickness direction of the cover body. Thus, the tissue specimen or the plurality of tissue specimens may be prevented from loss through the opening while ensuring that reagents may pass through the device via the cover, the base and the frame. A size of the opening in the cover body limits an area of the flexible sheet and thus a size of the tissue sample that may be pressed by the device of the present disclosure. Moreover, the opening of the cover body in combination with the matching base determines a size of the wax block that may be formed during an embedding process.

[0043] A device for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to embodiments of the present disclosure will be described below with reference to FIGS. 1 to 13.
[0044] As illustrated in FIGS. 1 to 13, according to embodiments of the present disclosure, a device 100, 200, 300, 400, 500 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder is provided. The device 100, 200, 300, 400, 500 includes a base 120, 220, a cover 130, 230, 330, 430, 530 and a frame 110, 210. The base 120, 220 has a cavity 121, 221 configured to accommodate the tissue specimen 900 or the plurality of tissue specimens 900. The cover 130, 230, 330, 430, 530 is coupled to the base 120, 220 and has an orientation structure 131, 231, 331, 431, 531 configured to orientate and secure the tissue specimen 900 or the plurality of tissue specimens 900 in the cavity 121, 221 of the base 120, 220. The base 120, 220, and the cover 130, 230, 330, 430, 530 are detachably coupled to the frame 110, 210. The orientation structure 131, 231, 331, 431, 531 includes a plurality of elastic ribs 1311, 2311, 3311, 4311, 5311 configured to provide a pressure on the tissue specimen 900 or the plurality of tissue specimens 900 and adjust the pressure according to a height of the tissue specimen 900 or heights of the plurality of tissue specimens 900; and a flexible sheet 1313, 2313, 3313, 4313, 5313 coupled to the plurality of elastic ribs 1311, 2311, 3311, 4311, 5311 and having a plurality of flexible portions 13131, 23131, 33131, 43131, 53131 configured to contact and wrap the tissue specimen 900 or the plurality of tissue specimens 900 independently.
[0045] In the device 100, 200, 300, 400, 500 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder, the orientation structure 131, 231, 331, 431, 531 includes the plurality of elastic ribs 1311, 2311, 3311, 4311, 5311, and the flexible sheet 1313, 2313, 3313, 4313, 5313 coupled to the plurality of elastic ribs 1311, 2311, 3311, 4311, 5311. Thus, the tissue specimen 900 or the plurality of tissue specimens 900 may be pre-orientated, the manual embedding may be bypassed to allow embedding automation, and the device 100, 200, 300, 400, 500 may secure the orientation of the tissue specimen 900 or the plurality of tissue specimens 900 from grossing to sectioning. The flexible sheet 1313, 2313, 3313, 4313, 5313 has a plurality of flexible portions 13131, 23131, 33131, 43131, 53131 configured to contact and wrap the tissue specimen 900 or the plurality of tissue specimens 900 independently. Thus, the device 100, 200, 300, 400, 500 is suitable for immobilizing a wide variety of types, shapes and sizes of the tissue specimen 900 or the plurality of tissue specimens 900 on the same plane.
[0046] In some embodiments, as illustrated in FIGS. 2 and 10 to 13, each of the plurality of flexible portions 13131, 23131, 33131, 43131, 53131 includes a waveform structure 13133, 23133, 33133, 43133, 53133 for coupling two adjacent elastic ribs 1311, 2311, 3311, 4311, 5311 of the plurality of elastic ribs 1311, 2311, 3311, 4311, 5311. Thus, the elastic ribs 1311, 2311, 3311, 4311, 5311 coupled to the waveform structure 13133, 23133, 33133, 43133, 53133 may adjust the pressure on the tissue specimen 900 or the plurality of tissue specimens 900 independently.
[0047] In some embodiments, as illustrated in FIGS. 2 and 10 to 13, the waveform structure 13133, 23133, 33133, 43133, 53133 has a thickness of 0.3-0.5mm, a width of 0.4-1mm and a length of 4-7mm. The size of the waveform structure 13133, 23133, 33133, 43133, 53133 has influence on the independence between the elastic ribs 1311, 2311, 3311, 4311, 5311 coupled to the waveform. The waveform structure 13133, 23133, 33133, 43133, 53133 having the size within the above scope may provide good independence between the elastic ribs 1311, 2311, 3311, 4311, 5311 coupled to the waveform structure 13133, 23133, 33133, 43133, 53133, and reduce a pressure acting on the tissue sample 900 to avoid crushing and cracking of the tissue sample 900 due to excessive stress, which in turn affects observation of a section of the tissue sample 900 under a microscope. Moreover, the waveform structure 13133, 23133, 33133, 43133, 53133 may fit better on the tissue sample 900 and wrap around the tissue sample 900, to render the tissue sample 900 to abut against the base 120, 220 tightly, which facilitates a doctor to better cut out a complete surface of the tissue sample 900 after the tissue sample 900 is embedded to form a wax block.
[0048] In some embodiments, as illustrated in FIGS. 2 and 10 to 13, each of the plurality of flexible portions 13131, 23131, 33131, 43131, 53131 includes a plurality of waveform structures 13133, 23133, 33133, 43133, 53133 coupled end to end. Thus, more elastic ribs 1311, 2311, 3311, 4311, 5311 coupled to the same flexible portion 13131, 23131, 33131, 43131, 53131 may be independent from each other.
[0049] In some embodiments, as illustrated in FIGS. 2 and 10-11, the plurality of waveform structures 13133, 23133, 33133 for each flexible portion 13131, 23131, 33131 is arranged in series to form a larger waveform structure. That is, extending directions of the plurality of waveform structures 13133, 23133, 33133 are collinear, and an extending direction of the larger waveform structure is also collinear with the extending directions of the plurality of waveform structures 13133, 23133, 33133. Thus, the elastic ribs 1311, 2311, 3311 coupled to the larger waveform structure may be independent from each other.
[0050] It could be understood that the extending direction of the waveform structure 13133, 23133, 33133 or the larger waveform structure refers to a travel direction of a waveform or a direction collinear with the travel direction of the waveform.
[0051] In some embodiments, as illustrated in FIG. 13, the plurality of waveform structures 53133 for each flexible portion 53131 is arranged in parallel to form a waveform-like structure having an extending direction perpendicular to an extending direction of each waveform structure 43133, 53133. That is, extending directions of the plurality of waveform structures 53133 for the same flexible portion 53131 are parallel, the plurality of waveform structures 53133 are coupled end to end to form the waveform-like structure, and the extending direction of the waveform-like structure is perpendicular to the extending directions of the plurality of waveform structures 53133. Thus, the elastic ribs 5311 coupled to the waveform-like structure may be independent from each other.
[0052] In some embodiments, as illustrated in FIG. 12, at least one of the plurality of waveform structures 43133 for each flexible portion 43131 is arranged perpendicular to the remaining of the plurality of waveform structures 43133. That is, an extending direction of the at least one of the plurality of waveform structures 43133 for the same flexible portion 43131 is perpendicular to the extending directions of the remaining of the plurality of waveform structures 43133. Although an overall shape of the connected plurality of waveform structures 43133 is not a waveform structure or a waveform-like structure, the plurality of elastic ribs 4311 connected to the overall shape remain independent of each other.
[0053] In some examples, each waveform structure 13133, 23133, 33133, 43133, 53133 may include a regular waveform, such as a sine waveform, a triangle waveform, a sawtooth waveform, or a square waveform. The regular waveform of the plurality of waveform structures 13133, 23133, 33133, 43133, 53133 may achieve a uniform wrapping effect on the tissue specimen 900 or the plurality of tissue specimens 900 for the plurality of flexible portions 13131, 23131, 33131, 43131, 53131. However, the present application is not limited to this, and in other examples, the waveform structure 13133, 23133, 33133, 43133, 53133 may also include an irregular waveform.
[0054] In some examples, the plurality of waveform structures 13133, 23133, 33133, 43133, 53133 on the same flexible portion 13131, 23131, 33131, 43131, 53131 has identical parameter. For example, each waveform structure 13133, 23133, 33133, 43133, 53133 on the same flexible portion 13131, 23131, 33131, 43131, 53131 has identical period and amplitude. However, the present application is not limited to this, and in other examples, the plurality of waveform structures on the same flexible portion has different parameters.
[0055] In some examples, the plurality of waveform structures 13133, 23133, 33133, 43133, 53133 on different flexible portions 13131, 23131, 33131, 43131, 53131 has identical parameter. That is, all the waveform structures 13133, 23133, 33133, 43133, 53133 of the cover 130, 230, 330, 430, 530 may have identical parameter. For example, each waveform structure 13133, 23133, 33133, 43133, 53133 of the cover 130, 230, 330, 430, 530 has identical period and amplitude. However, the present disclosure is not limited to this, and in other examples, parameter of the plurality of waveform structures on one flexible portion may be different from parameter of the plurality of waveform structures on another flexible portion.
[0056] In some embodiments, as illustrated in FIGS. 2, 10 and 12, the plurality of elastic ribs 1311, 2311, 4311 includes a first type rib 13111, 23111, 43111 and a second type rib 13113, 23113, 43113, and the first type rib 13111, 23111, 43111 is greater than the second type rib 13113, 23113, 43113 in length. The longer first type rib 13111, 23111, 43111 may avoid crushing or fracturing of the tissue specimen 900 or the plurality of tissue specimens 900, and the shorter second type rib 13113, 23113, 43113 may ensure that the tissue specimen 900 or the plurality of tissue specimens 900 will not be lost.
[0057] In some embodiments, as illustrated in FIGS. 2 and 10 to 13, each of the plurality of elastic ribs 1311, 2311, 3311, 4311, 5311 has a thickness of 0.3-0.5mm and a width of 0.4-1mm. The thickness and the width of elastic ribs 1311, 2311, 3311, 4311, 5311 may have influence on a force for immobilizing the uneven tissue specimen 900 or the plurality of tissue specimens 900 of different heights. The elastic ribs 1311, 2311, 3311, 4311, 5311 having the size within the above scope may provide proper force for immobilizing the uneven tissue specimen 900 or the plurality of tissue specimens 900 of different heights.
[0058] In some embodiments, as illustrated in FIGS. 2, 10 and 12, the first type rib 13111, 23111, 43111 is L-shaped, and the second type rib 13113, 23113, 43113 is S-shaped. The L-shape first type rib 13111, 23111, 43111 may provide a smaller pressure on the tissue specimen 900 or the plurality of tissue specimens 900 than the S-shaped second type rib 13113, 23113, 43113. The S-shape prevents the second type rib 13113, 23113, 43113 from exceeding an upper surface of the cover 130, 230, 430 when the device of the present disclosure presses tissue samples 900 having a thickness of 4 millimeters, which in turn results in an increase in a height of the device of the present disclosure and a reduction in the number of the device of the present disclosure that may be placed in a dehydration basket. Moreover, the S-shape increases the length of the second type rib 13113, 23113, 43113, which increases a force arm and thereby reduces a pressure acting on the tissue sample 900.
[0059] In some embodiments, as illustrated in FIGS. 2 and 10 to 13, the elastic ribs 1311, 2311, 3311, 4311, 5311 coupled to each flexible portion 13131, 23131, 33131, 43131, 53131 are arranged in a staggered manner along an extending direction of the flexible portion 13131, 23131, 33131, 43131, 53131. Thus, uniform stress on the tissue specimen 900 or the plurality of tissue specimens 900 may be ensured.
[0060] In some embodiments, as illustrated in FIGS. 2 and 10 to 13, each of the plurality of flexible portions 13131, 23131, 33131, 43131, 53131 is coupled to four to six elastic ribs 1311, 2311, 3311, 4311, 5311. Thus, the tissue specimen 900 or the plurality of tissue specimens 900 may well fit to the base 120, 220, 320, 420, 520.
[0061] In some embodiments, as illustrated in FIGS. 2 and 10 to 13, the plurality of flexible portions 13131, 23131, 33131, 43131, 53131 is arranged in parallel. Thus, the tissue specimen 900 or the plurality of tissue specimens 900 may be well wrapped by the flexible sheet 1313, 2313, 3313, 4313, 5313.
[0062] In some embodiments, as illustrated in FIG. 6, the cover 130 further includes a safety wall 1339 arranged on the flexible sheet 1313 and configured to avoid loss or cross contamination of the tissue specimen 900 or the plurality of tissue specimens 900. Thus, the tissue specimen 900 or the plurality of tissue specimens 900 may be prevented from loss or cross contamination.
[0063] In some embodiments, the cover 130 further includes a retaining wall 1337 having an outer peripheral face matching an inner peripheral face of the base 120. Thus the strength of the cover 130 may be enhanced, and the position of the cover 130 may be limited when the cover 130 is inserted into the base 120.
[0064] In some embodiments, the cover 130, 230 is rotatably coupled to the base 120, 220 through a hinge 140, 240. Thus, the cover 130, 230 and the base 120, 220 are coupled as an integrated component.
[0065] In some embodiments, the cover 130, 230, 330, 430, 530 further includes a cover body 133, 233, 333, 433, 533 detachably coupled to the base 120, 220, 320, 420, 520, and the flexible sheet 1313, 2313, 3313, 4313, 5313 is coupled to cover body 133, 233, 333, 433, 533 through the plurality of elastic ribs 1311, 2311, 3311, 4311, 5311. Thus, the cover body 133, 233, 333, 433, 533 may support the elastic ribs 1311, 2311, 3311, 4311, 5311 and the flexible sheet 1313, 2313, 3313, 4313, 5313, to form into one piece.
[0066] In some embodiments, the cover body 133, 233, 333, 433, 533 defines an opening 1331, 2331, 3331, 4331, 5331 extending through the cover body 133, 233, 333, 433, 533 in a thickness direction of the cover body 133, 233, 333, 433, 533, and the flexible sheet 1313, 2313, 3313, 4313, 5313 is located within the opening 1331, 2331, 3331, 4331, 5331 when viewed along the thickness direction of the cover body 133, 233, 333, 433, 533. Thus, the tissue specimen 900 or the plurality of tissue specimens 900 may be prevented from loss through the opening 1331, 2331, 3331, 4331, 5331 while ensuring that reagents may pass through the device 100, 200, 300, 400, 500 via the cover 130, 230, 330, 430, 530, the base 120, 220 and the frame 110, 210. A size of the opening 1331, 2331, 3331, 4331, 5331 in the cover body 133, 233, 333, 433, 533 limits an area of the flexible sheet 1313, 2313, 3313, 4313, 5313 and thus a size of the tissue sample 900 that may be pressed by the device of the present disclosure. Moreover, the opening 1331, 2331, 3331, 4331, 5331 of the cover body 133, 233, 333, 433, 533 in combination with the matching base determines a size of the wax block that may be formed during an embedding process.
[0067] In some embodiments, the cover body 133, 433 further includes a protrusion 1333, 4333 extending inwards from an inner peripheral wall of the opening 1331, 4331 and at least one of the plurality of elastic ribs 1311, 4311 is coupled to the protrusion 1333, 4333; the cover body 133, 433 further defines a groove 1335, 4335 recessed outwards from the inner peripheral wall of the opening 1331, 4331 and at least one of the plurality of elastic ribs 1311, 4311 is coupled to the groove 1335, 4335. The protrusion 1333, 4333 and the groove 1335, 4335 facilitate the uniform distribution of the plurality of elastic ribs 1311, 4311 on the plurality of flexible portions 13131, 43131.
[0068] A device for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to embodiments of the present disclosure will be described in detail below with reference to FIGS. 1 to 13.
[0069] FIG. 1 illustrates a perspective view of a device 100 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to a first embodiment of the present disclosure.
[0070] The device 100 includes a frame 110, a base 120 and a cover 130. The frame 110 is a support part for remaining parts of the device 100. The base 120 and the cover 130 are detachably coupled to the frame 110. The base 120 has a cavity 121 configured to accommodate the tissue specimen 900 or the plurality of tissue specimens 900. The cover 130 is coupled to the base 120 and has an orientation structure 131 configured to orientate and secure the tissue specimen 900 or the plurality of tissue specimens 900 in the cavity 121 of the base 120. The orientation structure 131 includes a plurality of elastic ribs 1311 and a flexible sheet 1313 coupled to the plurality of elastic ribs 1311. The plurality of elastic ribs 1311 is configured to provide a pressure on the tissue specimen 900 or the plurality of tissue specimens 900 and adjust the pressure according to a height of the tissue specimen 900 or heights of the plurality of tissue specimens 900. The flexible sheet 1313 has a plurality of flexible portions 13131 configured to contact and wrap the tissue specimen 900 independently. Thus, orientation and safety of the tissue specimen 900 or the plurality of tissue specimens 900 may be ensured during grossing, processing and embedding of the tissue specimen 900 or the plurality of tissue specimens 900.
[0071] The device 100 further includes a hinge 140, and the cover 130 is rotatably coupled to the base 120 through the hinge 140.
[0072] FIG. 2 illustrates a top view of a cover 130 of a device 100 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to a first embodiment of the present disclosure. The cover 130 includes a cover body 133. The cover body 133 has a substantially rectangular shape, and defines an opening 1331 extending through the cover body 133 in a thickness direction of the cover body 133, and the flexible sheet 1313 is located within the opening 1331 when viewed along the thickness direction of the cover body 133.
[0073] The plurality of flexible portions 13131 of the flexible sheet 1313 is arranged in parallel. As illustrated in FIG. 2, the flexible sheet 1313 includes three flexible portions 13131 extending in parallel in a length direction of the cover body 133. In this embodiment, the flexible portions 13131 are separate from each other. That is, the three flexible portions 13131 do not coupled to each other directly. Each of the three flexible portions 13131 is coupled to the cover body 133 through corresponding elastic ribs 1311. Thus, the three flexible portions 13131 may contact and wrap the tissue specimen 900 or the plurality of tissue specimens 900 independently.
[0074] Each flexible portion 13131 includes three waveform structures 13133 and two slotted rectangular structures 13135. The three waveform structures 13133 are coupled sequentially to form a larger waveform structure, and the two slotted rectangular structures 13135 are coupled to two ends of the larger waveform structure, respectively. Two ends of the each waveform structure 13133 are coupled to two elastic ribs 1311, respectively, and two adjacent waveform structures 13133 share a same elastic rib 1311.
[0075] The cover 130 includes twelve elastic ribs 1311, and four elastic ribs 1311 for each flexible portion 13131. The four elastic ribs 1311 coupled to each flexible portion 13131 include two first type ribs 13111 and two second type ribs 13113. The first type ribs 13111 are greater than the second type ribs 13113 in length. That is, the first type rib 13111 is a long elastic rib 1311, and the second type rib 13113 is a short elastic rib 1311. Each first type rib 13111 has an L-shape, and each second type rib 13113 has an S-shape.
[0076] The four elastic ribs 1311 coupled to each flexible portion 13131 are arranged in a staggered manner along an extending direction of the flexible portion 13131, i.e., the length direction of the cover body 133. Thus, uniform stress on the tissue specimen 900 or the plurality of tissue specimens 900 may be ensured. For example, the four elastic ribs 1311 coupled to each flexible portion 13131 is spaced apart in the length direction of the cover body 133, and the two first type ribs 13111 are located between two second type ribs 13113 in the length direction of the cover body 133. A lower second type rib 13113 is coupled to a trough of a lower waveform structure 13133, a lower first type rib 13111 is coupled to a peak of the lower waveform structure 13133 which is also a peak of a middle waveform structure 13133, an upper first type rib 13111 is coupled to a trough of the middle waveform structure 13133 which is also a trough of an upper waveform structure 13133, and an upper second type rib 13113 is coupled to a peak of the upper waveform structure 13133.
[0077] Due to the waveform structures 13133, the four elastic ribs 1311 coupled to the same flexible portion 13131 may be independent of each other and the flexible sheet 1313 may wrap the tissue specimen 900 or the plurality of tissue specimens 900 easily.
[0078] Each of the plurality of elastic ribs 1311 has a thickness of 0.3-0.5mm and a width of 0.4-1mm. Thus, the pressure on the tissue specimen 900 or the plurality of tissue specimens 900 may avoid fracturing, crushing and flipping of the tissue specimen 900 or the plurality of tissue specimens 900 during grossing, processing and embedding.
[0079] Each waveform structure 13133 has a thickness of 0.3-0.5mm, a width of 0.4-1mm and a length of 4-7mm. In some embodiments, a ratio of the width, the length and the thickness of the waveform structure 13133 may be 0.6: 1.5: 0.4. Thus, the flexible sheet 1313 may wrap the tissue specimen 900 or the plurality of tissue specimens 900 easily and snugly.
[0080] A distance of each waveform structure 13133, i.e., a size of each gap defined in each waveform structure 13133 along the length direction of the cover body 133, may be 0.5-1mm. Thus, loss of the tissue specimen 900 or the plurality of tissue specimens 900 may be avoided.
[0081] A segment of each L-shaped first type rib 13111 coupled to the waveform structure 13133, the S-shaped second type rib 13113, and a rising edge or a falling edge of the waveform structure 13133 are substantially parallel when viewed along the thickness direction of the cover body 133.
[0082] The cover body 133 further includes a protrusion 1333 extending inwards from an inner peripheral wall of the opening 1331, and at least one of the elastic ribs 1311 is coupled to the protrusion 1333. The cover body 133 further defines a groove 1335 recessed outwards from the inner peripheral wall of the opening 1331, and at least one of the elastic ribs 1311 is coupled to the groove 1335. Additionally, at least one of the elastic ribs 1311 is coupled to the inner peripheral wall of the opening 1331.
[0083] The cover body 133 includes four protrusions 1333 extending inwards from an inner peripheral wall of the opening 1331. Two of the four protrusions 1333 extend from an upper width portion of the inner peripheral wall of the opening 1331, and the other two of the four protrusions 1333 extend from a lower width portion of the inner peripheral wall of the opening 1331.
[0084] The cover body 133 defines two grooves 1335 in the inner peripheral wall of the opening 1331. One of the two grooves 1335 is defined in a left length portion of the inner peripheral wall of the opening 1331, and the other of the two grooves 1335 is defined in a right length portion of the inner peripheral wall of the opening 1331.
[0085] The protrusions 1333 and the grooves 1335 facilitate the arrangement of the plurality of elastic ribs 1311 and ensure the consistency of the plurality of elastic ribs 1311.
[0086] The left and middle upper second type ribs 13113 are coupled to the two upper protrusions 1333, respectively, and the right upper second type rib 13113 is coupled to the inner peripheral wall of the opening 1331. The right and middle upper first type ribs 13111 are coupled to the two upper protrusions 1333, respectively, and the left upper first type rib 13111 is coupled to the left groove 1335.
[0087] The right and middle lower second type ribs 13113 are coupled to the two lower protrusions 1333, respectively, and the left lower second type rib 13113 is coupled to the inner peripheral wall of the opening 1331. The left and middle lower first type ribs 13111 are coupled to the two lower protrusions 1333, respectively, and the right lower first type rib 13111 is coupled to the right groove 1335.
[0088] In combination with FIGS. 1 and 2, the cover 130 further includes a first recessed portion 135, an avoidance slot 137, and a hook portion 139; the base 120 further includes a second recessed portion 123; the frame 110 further includes a first snap 111, a second snap 113 and a third snap 115.
[0089] The first recessed portion 135 of the cover 130 corresponds in position to the second snap 113 of the frame 110 at a rear of the frame 110, the avoidance slot 137 of the cover 130 corresponds in position to the second snap 113 of the frame 110 at a front of the frame 110, the hook portion 139 of the cover 130 corresponds in position to the third snap 115 of the frame 110, and the second recessed portion 123 of the base 120 corresponds in position to the first snap 111 of the frame 110. Thus, the cover 130 may be assembled to the frame 110 through snap-fit between the first recessed portion 135 and the second snap 113 and a snap-fit between the hook portion 139 and the third snap 115, and the base 120 may be assembled to the frame 110 through a snap-fit between the second recessed portion 123 and the first snap 111.
[0090] FIG. 3 illustrates cross sectional views of a device 100 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to a first embodiment of the present disclosure. As illustrated in FIG. 3, one uneven tissue specimen 900 or the plurality of different tissue specimens 900 having different sizes is placed into the cavity 121 of the base 120, the cover 130 is then closed, and the uneven tissue specimen 900 or the plurality of different tissue specimens 900 are pressed against a bottom wall of the base 120 within the cavity 121.
[0091] The three flexible portions 13131 are separate from each other, and the elastic ribs 1311 on different flexible portions 13131 are independent from each other. The elastic ribs 1311 on the same flexible portion 13131 are coupled through the waveform structures 13133, and the elastic ribs 1311 on the same flexible portion 13131 are also independent from each other. Thus, the pressure on the uneven tissue specimen 900 or the plurality of different tissue specimens 900 may be adjusted according to heights of different portions of the uneven tissue specimen 900 or heights of the plurality of different tissue specimens 900, to ensure uniform stress on the uneven tissue specimen 900 or the plurality of different tissue specimens 900.
[0092] Furthermore, each flexible portion 13131 includes a plurality of waveform structures 13133, thus each flexible portion 13131 may deform easily according to the shape or contour of the uneven tissue specimen 900 or of the plurality of different tissue specimens 900, to wrap the uneven tissue specimen 900 or the plurality of different tissue specimens 900 snugly.
[0093] FIG. 4 illustrates a cutaway view of a device 100 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to a first embodiment of the present disclosure and a partially enlarged view of the cutaway view. As illustrated in FIG. 4, the three flexible portions 13131 immobilize the plurality of tissue specimens 900 independently along the length direction of the cover body 133. Furthermore, the first type rib 13111 is independent of the second type rib 13113 on the same flexible portion 13131 due to the waveform structure 13133. As illustrated in the enlarged view, a part of the waveform structure 13133 and the first type rib 13111 are elevated by a tissue specimen 900, and the other part of the waveform structure 13133 serves as a buffer to keep the second type rib 13113 in an original place.
[0094] FIG. 5 illustrates a sectional view of a device 100 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to a first embodiment of the present disclosure. As illustrated in FIG. 5, the cover 130 further includes a plurality of safety walls 1339 extending upwards in the thickness direction of the cover body 133 from a top face of each flexible portion 13131. The plurality of safety walls 1339 may avoid loss or cross contamination of the tissue specimen 900 or the plurality of tissue specimens 900. For example, the plurality of safety walls 1339 may be arranged at the peaks and / or the troughs of the waveform structures 13133. Moreover, the plurality of safety walls 1339 on each flexible portion 13131 may be arranged in two rows along the length direction of the cover body 133.
[0095] FIG. 6 illustrates a perspective view of a cover 130 of a device 100 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to a first embodiment of the present disclosure. As illustrated in FIG. 6, the cover 130 further includes a retaining wall 1337 extending downwards in the thickness direction of the cover body 133 from a bottom face of the cover body 133 and around the opening 1331 of the cover body 133. An outer peripheral face of the retaining wall 1337 matches an inner peripheral face of the base 120, and thus the strength of the cover 130 may be enhanced, and the position of the cover 130 may be limited when the cover 130 is inserted into the base 120. For example, the outer peripheral face of the retaining wall 1337 tilted downwards and inwards, and the inner peripheral face of the base 120 tilted upwards and outwards.
[0096] FIG. 7 illustrates a sectional view of a device 100 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to a first embodiment of the present disclosure. As illustrated in FIG. 7, the second type ribs 13113 have an S-shape when no tissue specimen 900 is accommodated between the cover 130 and the base 120.
[0097] FIG. 8 illustrates a sectional view of a device 100 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to a first embodiment of the present disclosure, in which a tissue specimen 900 or the plurality of tissue specimens 900 is accommodated between the cover 130 and the base 120. As illustrated in FIG. 8, the plurality of second type ribs 13113 is deformed to press the tissue specimen 900 or the plurality of tissue specimens 900 against the bottom wall of the base 120, to prevent the tissue specimen 900 or the plurality of tissue specimens 900 (e.g., having a thickness of 4mm) from exceeding the top face of the cover 130. Moreover, the second type rib 13113 may provide a larger pressure on the tissue specimen 900 or the plurality of tissue specimens 900 than the first type rib 13111, to ensure that the tissue specimen 900 or the plurality of tissue specimens 900 will not be lost. The first type rib 13111 may provide a smaller pressure on the tissue specimen 900 or the plurality of tissue specimens 900 than the second type rib 13113 to avoid crushing or fracturing of the tissue specimen 900 or the plurality of tissue specimens 900. As illustrated in FIG. 2, the plurality of first type ribs 13111 acts on a middle area of each flexible portion 13131 along the length direction of the cover body 133. Thus, the tissue specimen 900 or the plurality of tissue specimens 900 may be prevented from crushing or fracturing.
[0098] FIG. 9 illustrates a perspective view of a device 200 for immobilizing a tissue specimen 900 or a plurality of tissue specimens 900 for an automated embedder according to a second embodiment of the present disclosure. As illustrated in FIG. 9, the device 200 includes a frame 210, a base 220 and a cover 230. The frame 210 is a support part for remaining parts of the device 200. The base 220 and the cover 230 are detachably coupled to the frame 210. The base 220 has a cavity 221 configured to accommodate the tissue specimen 900 or the plurality of tissue specimens 900. The cover 230 is coupled to the base 220 and has an orientation structure 231 configured to orientate and secure the tissue specimen 900 or the plurality of tissue specimens 900 in the cavity 221 of the base 220. The orientation structure 231 includes a plurality of elastic ribs 2311 and a flexible sheet 2313 coupled to the plurality of elastic ribs 2311. The plurality of elastic ribs 2311 is configured to provide a pressure on the tissue specimen 900 or the plurality of tissue specimens 900 and adjust the pressure according to a height of the tissue specimen 900 or heights of the plurality of tissue specimens 900. The flexible sheet 2313 has a plurality of flexible portions 23131 configured to contact and wrap the tissue specimen 900 independently. Thus, orientation and safety of the tissue specimen 900 or the plurality of tissue specimens 900 may be ensured during grossing, processing and embedding of tissue specimen 900 or the plurality of tissue specimens 900.
[0099] The device 200 further includes a hinge 240, and the cover 230 is rotatably coupled to the base 220 through the hinge 240.
[0100] The frame 210 has a structure similar to the frame 110. The detailed structure of the frame 210 will not repeated herein.
[0101] The base 220 has a structure similar to the base 120 except that the cavity 221 of the base 220 is formed by recessing a bottom wall of the base 220. That is, the base 220 defines a first sub-cavity and a second sub-cavity in fluid communication with the first sub-cavity; the first sub-cavity is configured to receive the cover body 233 of the cover 230, and the second sub-cavity is configured to receive the orientation structure 2321 of the cover 230. The detailed structure of the base 220 will not repeated herein.
[0102] FIG. 10 illustrates a top view of a cover 230 of a device 200 for immobilizing a tissue specimen or a plurality of tissue specimens for an automated embedder according to a second embodiment of the present disclosure. The cover 230 includes a cover body 233. The cover body 233 has a substantially rectangular shape, and defines an opening 2331 extending through the cover body 233 in a thickness direction of the cover body 233, and the flexible sheet 2313 is located within the opening 2331 when viewed along the thickness direction of the cover body 233.
[0103] The plurality of flexible portions 23131 of the flexible sheet 2313 is arranged in parallel. As illustrated in FIG. 10, the flexible sheet 2313 includes three flexible portions 23131 extending in parallel in a length direction of the cover body 233. In this embodiment, the flexible portions 23131 are separate from each other. That is, the three flexible portions 23131 do not coupled to each other directly. Each of the three flexible portions 23131 is coupled to the cover body 233 through corresponding elastic ribs 2311. Thus, the three flexible portions 23131 may contact and wrap the tissue specimen 900 or the plurality of tissue specimens 900 independently.
[0104] Each flexible portion 23131 includes three waveform structures 23133. The three waveform structures 23133 are coupled sequentially to form a larger waveform structure. Two ends of the each waveform structure 23133 are coupled to two elastic ribs 2311, respectively, and two adjacent waveform structures 23133 share a same elastic rib 2311.
[0105] The cover includes twelve elastic ribs 2311, and four elastic ribs 2311 for each flexible portion 23131. The elastic ribs 2311 coupled to a middle flexible portion 23131 include two first type ribs 23111 and two second type ribs 23113; the elastic ribs 2311 coupled to a left flexible portion 23131 include three first type ribs 23111 and one second type ribs 23113; and the elastic ribs 2311 coupled to a right flexible portion 23131 include three first type ribs 23111 and one second type ribs 23113. The first type ribs 23111 are greater than the second type ribs 23113 in length. Each first type rib 23111 has an L-shape, and each second type rib 23113 has an S-shape.
