Description

Technical Field

[0001] The utility model relates to the technical field of sampling molds, and particularly relates to a simple sampling mold for maintaining the directionality of biological tissues. Background Technique

[0002] Some biological tissues have directionality. For example, myocardial tissue and intestinal tissue will present different tissue morphologies when sliced in different directions. For example, when the myocardial tissue is longitudinally sliced, it will present a striped shape, and when it is transversely sliced, it will present a circular shape. According to the different experimental needs of researchers, slices in different directions should be taken.

[0003] However, before slicing, the sample needs to be fixed and embedded to make an embedding head, that is, a specimen. Once the specimen is fixed, the direction cannot be changed, that is, the longitudinal and transverse cutting surfaces cannot be changed. Therefore, the direction of the sample needs to be determined before fixation.

[0004] During the use of existing biological tissue sampling molds, although they can sample biological tissues, they cannot determine the direction of the sample, resulting in the inability to distinguish the direction of the sample during subsequent fixation of the sample, affecting the observation effect of researchers. At the same time, it is not convenient to pick up and press the mold, resulting in troublesome operation when pressing the sample, making it inconvenient for the staff to operate the small-volume mold, thus reducing the guiding and pressing properties of traditional biological tissue sampling molds. For this reason, a simple sampling mold for maintaining the directionality of biological tissues is introduced. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a simple sampling mold for maintaining the directionality of biological tissues, which has the advantages of good pressing property and good guiding property, and solves the problems raised in the above background technique.

[0006] The utility model provides the following technical solution: A simple sampling mold for maintaining the directionality of biological tissues, including a mold body, an outer wall of the mold body is fixedly assembled with a limiting block, an outer wall of the limiting block is provided with a steel bar, one end outer wall of the steel bar is fixedly assembled with a threaded bar, the other end of the steel bar is fixedly assembled with a handle, and an anti-slip groove is opened at the top of the handle.

[0007] As a preferred technical solution of the utility model: An ultra-thin blade is fixedly assembled at the bottom of the mold body, and a threaded groove is opened on the outer wall of the limiting block.

[0008] As a preferred technical solution of the utility model: The threaded bar is adapted to the inner wall of the threaded groove, and the steel bar is threadedly connected to the inner wall of the threaded groove through the threaded bar.

[0009] As a preferred technical solution of the present utility model: The handle is made of rubber, and anti-slip grooves are respectively formed at the upper and lower ends of the handle.

[0010] As a preferred technical solution of the present utility model: The handle is fixedly assembled with the inner wall of the threaded groove through a steel bar and a threaded bar, and the ultra-thin blade has the same shape as the mold body.

[0011] As a preferred technical solution of the present utility model: There are two limiting blocks, steel bars and handles, and the two limiting blocks, steel bars and handles are respectively located on the outer wall of the mold body.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] 1. For the simple sampling mold for maintaining the directionality of biological tissues, when pressing the mold body, by the user picking up the handles at both ends of the mold body, the handles and the steel bars support the mold body. The anti-slip effect is achieved through the anti-slip grooves formed at the top of the handle, so that the handle will not easily slip out of the hand when picking up the handle, avoiding damage to the biological tissue caused by the handle falling off during pressing. At the same time, the steel bar is threadedly connected with the threaded groove inside the limiting block through the threaded bar to connect the steel bar and the handle, so as to support the limiting block for the user to press.

[0014] 2. For the simple sampling mold for maintaining the directionality of biological tissues, by setting the mold body into a cuboid with a width of 1 mm, a length of 2 mm and a height of 1 mm, the mold body drives the ultra-thin blade to distinguish the direction of the sample after cutting the biological tissue, avoiding the difficulty in accurately judging its direction during the subsequent fixation of the sample, resulting in an incorrect sectioning direction when fixing the specimen, thus affecting the observation results of the researcher.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 - Figure 4 A simple sampling mold for maintaining the directionality of biological tissues comprises a mold body 1, a limit block 2 is fixedly assembled on the outer wall of the mold body 1, a steel bar 3 is arranged on the outer wall of the limit block 2, a threaded bar 7 is fixedly assembled on the outer wall of one end of the steel bar 3, a handle 4 is fixedly assembled on the other end of the steel bar 3, and an anti-slip groove 8 is arranged on the top of the handle 4.

[0022] In the above structure, during the process of pressing the mold body 1, the operator needs to hold the handles 4 at both ends thereof, and through the synergistic effect of the handles 4 and the steel bar 3, effective support for the mold body 1 is achieved. In order to enhance the holding stability, the top of the handle 4 is designed with an anti-slip groove 8 to provide an anti-slip effect, ensuring that the handle 4 is not easy to slip out of the hand during operation, thereby preventing damage to biological tissues caused by the handle 4 falling off. In addition, the steel bar 3 and the threaded groove 6 inside the limit block 2 are firmly connected through the threaded connection of the threaded bar 7. This design not only connects the steel bar 3 and the handle 4, but also enhances the support strength for the limit block 2, making it convenient for the user to perform the pressing operation smoothly.

[0023] In a preferred embodiment: an ultra-thin blade 5 is fixedly mounted on the bottom of the mold body 1 , and a thread groove 6 is formed on the outer wall of the limiting block 2 .

[0024] In the above structure, the mold body 1 is constructed into a rectangular structure with a width of one millimeter, a length of two millimeters, and a height of one millimeter. The structure is designed to drive the ultra-thin blade 5 to clearly identify the direction of the sample after performing biological tissue cutting, thereby preventing the direction judgment problem that may be encountered in the subsequent sample fixation process, thereby ensuring that researchers can obtain accurate and reliable results during the observation process.

[0025] In a preferred embodiment, the thread strip 7 is matched with the inner wall of the thread groove 6 , and the steel strip 3 is threadedly connected with the inner wall of the thread groove 6 via the thread strip 7 .

[0026] In the above structure, there will be no jamming when the thread strip 7 rotates on the inner wall of the thread groove 6, and the steel bar 3 is also fixed when the thread strip 7 is threadedly connected to the thread groove 6.

[0027] In a preferred embodiment: The handle 4 is made of rubber, and anti-slip grooves 8 are respectively formed at the upper and lower ends of the handle 4.

[0028] In the above structure, the handle 4 is made of rubber, so that when the user picks up the handle 4 for use, it will not cause damage to the user's hand. At the same time, through the anti-slip grooves 8 at the upper and lower ends of the handle 4, the use of the anti-slip grooves 8 is made more stable.

[0029] In a preferred embodiment: The handle 4 is fixedly assembled with the inner wall of the thread groove 6 through the steel bar 3 and the thread bar 7, and the ultra-thin blade 5 has the same shape as the mold body 1.

[0030] In the above structure, by connecting the thread bar 7 with the inner wall of the thread groove 6, the handle 4 is limited. Since the ultra-thin blade 5 has the same shape as the mold body 1, the sample cut by the ultra-thin blade 5 is the same as the space inside the inner wall of the mold body 1.

[0031] In a preferred embodiment: The number of the limiting blocks 2, the steel bars 3 and the handles 4 is two, and the two limiting blocks 2, the steel bars 3 and the handles 4 are respectively located on the outer wall of the mold body 1.

[0032] In the above structure, through the two limiting blocks 2, the steel bars 3 and the thread bars 7, when cutting biological tissue, the sample has the same shape as the inner wall of the mold body 1, so that the cut sample will not have different situations on both sides.

[0033] Working principle: During the operation, the staff needs to hold the handles 4 equipped at both ends, and use the cooperation between the handle 4 and the steel bar 3 to firmly support the mold body 1. In addition, the anti-slip structure anti-slip groove 8 specially provided at the top of the handle 4 effectively prevents the handle 4 from falling off due to hand slipping during the operation, thus avoiding potential damage to the biological tissue that may be caused by the fall. At the same time, the steel bar 3 is tightly connected to the interface thread groove 6 inside the limiting block 2 through a precise threaded connection mechanism thread bar 7, realizing a firm connection between the steel bar 3 and the handle 4, and further providing a stable pressing support for the user. Since the size of the mold body 1 is accurately set to a cuboid shape with a width of one millimeter, a length of two millimeters, and a height of one millimeter, this design endows the mold body 1 with the function of clearly indicating the sample direction after cutting biological tissue, avoiding the wrong section direction caused by misjudging the sample direction, and thus ensuring that the observation results of the researcher are not affected.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
