AI Technical Summary

Technical Problem

Existing biopsy sample preservation devices often result in samples floating or settling, leading to uneven tissue fixation. The rough injection of preservation solution damages sample integrity, and the lack of effective zoning and labeling mechanisms causes sample confusion, affecting diagnostic accuracy.

Method used

The design employs multiple independent preservation tubes, combined with a two-way convection buffer structure and a double sealing system, to ensure that the samples are suspended and fixed, avoiding cross-contamination. A labeling mechanism is used to distinguish samples and protect their integrity and activity.

Benefits of technology

This allows for the separate and isolated storage of samples, avoiding cross-contamination and confusion, ensuring the integrity and activity of samples during preservation, and improving the accuracy and efficiency of pathological observation.

Abstract

本发明涉及活检样本保存技术领域，具体涉及一种甲乳外科手术活检样本保藏装置，包括瓶体，瓶体顶部开口处设置有封口件，还包括保藏管，设置有若干根，且分别间隔分布在瓶体内，并与封口件可拆卸连接；双流向缓冲卸力机构，竖向设置在保藏管内，且与保藏管下端部相连接；撬动组件，设置在保藏管内，且与双流向缓冲卸力机构相连接，并与瓶体的瓶颈内侧相抵接，解决了现有装置所采用的保藏方式使得样本易漂浮或沉降，致样本固定不均，影响细胞形态保存与病理观察，且保藏液注入粗放，冲击组织表面，破坏样本完整性；样本易混淆，难精准对应，样本会因接触空气或容器内壁，致组织干燥、变形或活性降低，影响诊断准确性的问题。
