Problems solved by technology

[0003] When making spinal cord tissue specimens for coronal and sagittal slices, the spinal cord tissue is usually embedded in a circular tubular embedding mold suitable for the structure and size of the spinal cord tissue, but the inner cavity of the circular tubular embedding mold The small cross-sectional area of ​​the body makes it difficult for the operator to remove the specimen from the embedding mold
In addition, because the bottom surface area of ​​the spinal cord tissue specimen formed by the above-mentioned embedding mold is also small, it is impossible to achieve better support for the specimen, which is not conducive to the operator cutting the specimen.

Embodiment 1

[0034] In order to facilitate the understanding of this embodiment, the coronal slice specimen and the sagittal slice specimen are now described. Coronal section refers to cutting the specimen on the coronal plane, and sagittal section refers to cutting the specimen on the sagittal plane. The coronal plane refers to the plane formed by the vertical axis and the transverse axis and all planes parallel to it. As far as the human body is concerned, the coronal plane refers to the cross-section that cuts the human body longitudinally into two parts, the front and back. In this embodiment, the vertical axis Refers to the axis of the spinal cord. The sagittal plane refers to the plane formed along the vertical axis and the longitudinal axis and all planes parallel to it. As far as the human body is concerned, the sagittal plane refers to the section that divides the human body into left and right parts. In this embodiment, the vertical Axis refers to the axial direction of the spin...

Embodiment 2

[0048] Figure 6 The sectional view of the spinal cord embedding mold that embodiment two provides, as Figure 6 As shown, this embodiment provides a spinal cord embedding mold 1. For the sake of brevity, only the differences from Embodiment 1 are described: the first forming part 121 is a shell with an opening, and the second forming part 122 It is a mounting plate, which is plugged into the opening of the housing, and the base molding cavity 123 is formed by the mounting plate matching the housing. Specifically, the internal shape and size of the housing are adapted to the shape and size of the mounting plate, and then The base molding cavity 123 with a better sealing effect is obtained, and the leakage of the embedding agent poured into the mold is avoided, the waste of the embedding agent is reduced, and the utilization rate of the embedding agent is improved. In addition, in another embodiment, the first forming part 121 is a mounting plate, and the second forming part 1...

Abstract

The invention relates to the technical field of biological tissue embedding, and especially relates to a spinal cord embedding mold. The spinal cord embedding mold provided by the invention comprisesa specimen tube and a base forming mechanism, and the base forming mechanism is arranged at one end of the specimen tube and comprises a first forming part and a second forming part, wherein the firstforming part and the second forming part are detachably connected and jointly form a base forming cavity, and the base forming cavity is communicated with an inner cavity of the specimen tube. The cross sectional area of the inner cavity is smaller than that of the base forming cavity. Due to the fact that the first forming part and the second forming part are separated, a specimen can be taken out of an opening of the base forming cavity, so the technical problem that a coronary slice specimen and a sagittal slice specimen of spinal cord tissue are difficult to take out of a mold can be solved. Besides, a specimen base with the large cross section area is obtained through the base forming cavity, a good supporting effect can be achieved on the specimen, and the problem that the coronaryslice specimen and the sagittal slice specimen of spinal cord tissue are poor in supporting effect is solved.

Description

technical field [0001] The invention relates to the technical field of biological tissue embedding, in particular to a spinal cord embedding mold. Background technique [0002] Frozen section technique is often used in surgery for rapid diagnosis of pathology. Frozen section is a method of rapidly cooling tissue to a certain hardness under low temperature conditions, and then sectioning. The main steps include: sampling, fixing, embedding, sectioning and staining. Wherein, the embedding step specifically includes: after placing the biological tissue into the embedding mold, adding an appropriate amount of embedding agent (such as: paraffin, gelatin, etc.) Freeze for about 10 minutes to obtain embedded biological tissue samples. [0003] When making spinal cord tissue specimens for coronal and sagittal slices, the spinal cord tissue is usually embedded in a circular tubular embedding mold suitable for the structure and size of the spinal cord tissue, but the inner cavity of...
