Description

Technical Field

[0001] This utility model relates to the field of embedding cassette technology, and in particular to an embedding cassette for tissue sampling with adjustable internal space. Background Technology

[0002] Embedding cassettes are an indispensable consumable in pathological tissue examination and processing. They are mainly used to hold and fix collected tissue samples for dehydration and to serve as a scaffold for embedding tissue for subsequent sectioning. Current embedding cassettes consist of a body and an openable lid. The body is a single, undivided unit, offering advantages such as simple structure and ease of use and cleaning. However, in clinical practice, various tissues are frequently encountered, such as tubular (fallopian tubes, ureters, etc.) and cystic (ovarian cysts, teratomas, etc.) ESD specimens. When collecting these, the embedding cassette needs to be divided to allow for upright or horizontal placement, facilitating the location of the embedding surface during embedding. Current embedding cassettes cannot effectively fulfill these functions.

[0003] Existing technologies also include some embedding cassettes with internal divisions, such as the Chinese utility model patent with application number CN202120782108.6, entitled "An Embedding Cassette for ESD Specimens." This cassette, through height control and the placement of partitions, prevents tissue strips from rolling or bending within the cassette, allowing for more effective identification of lesions at the mucosal horizontal and vertical cutting margins, depth of invasion, and timely detection of lymphatic and vascular infiltration. However, its partitions are vertically fixed to the bottom of the lower cassette, thus fixing the internal space of the embedding cassette. While this meets the embedding needs of special tissues such as ESD specimens, it limits its applicability to ordinary tissue samples, resulting in limited versatility.

[0004] For example, Chinese utility model patent application number CN202323519453.9, entitled "An Embedding Box for ESD Specimens", uses a manual rotating adjustment handle to drive the transmission shaft to rotate, which facilitates the adjustment of the length of the telescopic mechanism, the increase of the distance between two adjacent partitions, and the simultaneous adjustment of the size of multiple storage areas. However, its structure is complex and inconvenient to operate. The partitions are not easy to disassemble, and the removal of tissues after embedding and subsequent cleaning and disinfection are inconvenient. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an embedding box for tissue sampling with adjustable internal space, which can divide and adjust the internal space of the embedding box to achieve tissue embedding in an upright or horizontal manner. It has strong versatility, simple structure, and is convenient to operate and use.

[0006] This utility model is achieved by the following technical solution: an embedding box for tissue sampling with adjustable internal space, comprising: a box body and a box cover that can be opened and closed and is disposed on the upper end of the box body, wherein the box body is provided with a detachable partition structure that divides the interior of the box body into multiple embedding spaces of adjustable size.

[0007] Furthermore, the segmentation structure includes several longitudinal partitions and several transverse partitions, and the longitudinal partitions and transverse partitions are detachably connected.

[0008] Furthermore, the box body includes a box bottom, left and right side panels, a box rear panel, and a box front panel. The bottom of the box bottom is provided with through holes evenly distributed. The left and right side panels, the box rear panel, and the box front panel are fixed to the left, right, rear, and front edges of the box bottom.

[0009] Furthermore, the longitudinal partition plate and the transverse partition plate have the same structure, both including a longitudinal plate body and longitudinal slots evenly spaced at the upper end of the longitudinal plate body. The transverse longitudinal plate body and the longitudinal longitudinal plate body are connected by the longitudinal slots. After the connection, the top and bottom ends of the transverse plate body and the longitudinal plate body are horizontal, and their top ends are horizontal with the inside of the box body.

[0010] Furthermore, multiple grooves are symmetrically and evenly arranged on the left and right side plates of the box, and the dividing structure is installed in the grooves.

[0011] Furthermore, the horizontal partition plate includes a horizontal plate body and mounting ears. Two mounting ears are symmetrically fixed at both ends of the horizontal plate body. The two ends of the horizontal plate body are fixed in the groove by the two mounting ears. Horizontal slots are provided at equal intervals on the horizontal plate body. The vertical partition plate and the horizontal partition plate are inserted into each other through the slots. After insertion, the top and bottom of the vertical partition plate and the horizontal partition plate are horizontal, and their tops are horizontal with the inside of the box body.

[0012] Furthermore, the box body is also evenly provided with through holes, the box lid is hinged to the rear end of the box body, a buckle is fixed at the center of the lower front end of the box lid, and a hole that cooperates with the buckle is provided at the center of the front side of the box body.

[0013] Compared with existing technologies, the advantages of this utility model are as follows: This utility model provides an embedding cassette for tissue sampling with adjustable internal space. The cassette's interior is divided into multiple adjustable embedding spaces, allowing for vertical or horizontal embedding of tissues within a certain size range. The dividing structure allows for easy removal of the entire cassette, enhancing its versatility. The easy installation and disassembly of the dividing structure also facilitates tissue removal, subsequent cleaning, and disinfection after embedding. Attached Figure Description
