Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical auxiliary products technology, specifically to a pathological tissue embedding forceps. Background Technology
[0002] Embedding of pathological tissue is a core step in histological slide preparation. By embedding the processed tissue sample in paraffin or other embedding agents, it is given a certain degree of hardness and shape, laying the foundation for subsequent precise sectioning and microscopic observation.
[0003] The complete process of embedding pathological tissues encompasses five major stages: fixation, dehydration, clearing, paraffin infiltration, and embedding. Fixation uses formalin and other reagents to maintain the original morphology of the tissue; dehydration involves gradually replacing water with gradient alcohols (70%-100%); clearing uses xylene and other reagents instead of alcohol to achieve compatibility with paraffin; paraffin infiltration allows molten paraffin to fully penetrate the tissue in a constant temperature chamber; embedding requires placing the paraffin-infiltrated tissue in a mold and arranging it orientably (e.g., vertical embedding of skin, exposing the cut surfaces of luminal structures), pouring in liquid paraffin, and then cooling and solidifying.
[0004] Maintaining tissue planarity is crucial for ensuring section quality during pathological tissue embedding. Currently, medical staff primarily achieve tissue planarization through two methods: localized pressure with forceps or overall pressure with weights (see reference). Figure 6 and Figure 7 (as shown in the figure). However, both methods have obvious problems. When using tweezers to press, point pressure is inevitably applied, which can easily cause tissue damage, deformation or breakage. Although applying weights can achieve uniform force, it is necessary to use tweezers to clamp the tissue into the mold first, and then use another weight to apply pressure. This requires switching back and forth, resulting in low efficiency. When processing a large number of samples continuously, the operation is cumbersome.
[0005] Therefore, how to design a pathological tissue embedding forceps that can avoid deforming or fragmenting tissue samples and is suitable for continuous processing of large batches of samples is a technical problem that has not yet been solved in the existing technology. Utility Model Content
[0006] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects of the prior art, which is that the forceps pressing easily causes point pressure, resulting in tissue damage, deformation or fragmentation; and the weight pressure is uniform but inefficient and not suitable for large-scale continuous operation. Thus, a pathological tissue embedding forceps can be provided that can avoid tissue sample deformation or fragmentation and is suitable for continuous processing of large batches of samples.

[0019] As a preferred embodiment, the other side of the pressure-applying component is provided with a connecting component, the connecting component including a connecting shaft with external threads; the second clamping arm is provided with an internally threaded blind hole, and the connecting shaft is screwed into the internally threaded blind hole, thereby detachably mounting the pressure-applying component on the second clamping arm.
[0020] This utility model also provides a pathological tissue embedding forceps, comprising:
[0021] The second forceps body includes a first clamping arm and a second clamping arm; one end of the first clamping arm and the second clamping arm are fixedly connected, and the other end forms a second clamping end. A deformation space is formed between the two second clamping ends, and the axes of the two second clamping ends form an angle of 110°-130° with the axes of the first clamping arm and the second clamping arm, respectively; the second clamping end is suitable for clamping tissue samples.

[0033] The technical solution provided by this utility model has the following advantages:
[0034] 1. The pathological tissue embedding forceps of this utility model includes a first forceps body and a pressure-applying component; wherein, the first forceps body includes a first clamping arm and a second clamping arm; one end of the first clamping arm and the second clamping arm are fixedly connected, and the other end forms a first clamping end, a deformation space is formed between the two first clamping ends, and the first clamping end is pointed and suitable for clamping tissue samples; the pressure-applying component is detachably installed on the outer side wall of the second clamping arm near the first clamping end, and the pressure-applying component has a pressure-applying surface, which is a stainless steel plane.
[0035] When embedding pathological tissue, medical staff hold embedding forceps, aligning the first clamping end with the paraffin-impregnated tissue. They simultaneously press the first and second clamping arms inward with their thumb and forefinger, clamping the tissue tightly. The tissue is then transferred to a metal mold containing liquid paraffin. After placement, the wrist is rotated inward to adjust the forceps angle, allowing for vertical pressure on the tissue. The pressure surface is then pressed downwards until the tissue is flat and adheres to the bottom of the mold. Once the tissue is confirmed to be stable, liquid paraffin is added to completely cover it. After cooling and solidification, the embedding is complete. This novel pathological tissue embedding forceps, by pressing the tissue downwards with the pressure surface, ensures uniform force on the tissue, preventing deformation or fragmentation during pressing. It is also simple and efficient to operate, requiring only wrist rotation to press the tissue, making it suitable for continuous processing of large batches of tissue samples.

[0037] When using the pathological tissue embedding forceps of this invention, hold the forceps and align the second clamping end with the paraffin-impregnated tissue. Simultaneously press the first and second clamping arms inward with your thumb and forefinger to clamp the tissue tightly. Then transfer the tissue into a metal mold containing liquid paraffin. After the tissue is placed, rotate your wrist outward to adjust the angle of the forceps, so that the pressing element can be pressed perpendicularly to the tissue. Then, press the tissue downward with the pressing surface until the tissue is flat and adheres to the bottom of the mold. After confirming the tissue is stable, add more liquid paraffin to completely cover the tissue. After cooling and solidification, the embedding is complete. The pathological tissue embedding forceps of this invention, by pressing the tissue downward with the pressing surface, ensures uniform force on the tissue, preventing deformation or breakage.
