Description

Technical Field

[0001] The present invention belongs to the technical field of pathological sampling, and in particular relates to an intelligent robot system for sampling small specimens of pathological samples and a sampling method. Background Art

[0002] Pathological diagnosis is a core component of disease diagnosis, and tissue specimen collection is a key step in the pathology workflow. However, the current pathology specimen collection process presents numerous significant challenges. First, physicians must spend extended periods handling patient tissue samples at the specimen collection station, directly contacting formalin (a widely used tissue fixative). Short-term exposure can cause conjunctival congestion, respiratory irritation, headaches, nausea, and even acute poisoning, while long-term exposure increases the risk of nasopharyngeal cancer and leukemia. Second, manual specimen collection is labor-intensive and can lead to physician overload and operational errors. Furthermore, specimen thickness and orientation rely heavily on personal experience, compromising subsequent diagnostic accuracy. Currently, several measures are being adopted to mitigate these challenges, such as enhanced ventilation systems, upgraded protective equipment, and alternative fixatives. However, biosafety cabinets only partially reduce formaldehyde concentrations but cannot completely prevent exposure. Fully enclosed protective suits are bulky and restrict operational flexibility. Alternatives such as ethanol are costly and poorly fixative for specific tissues, such as fat.

[0003] During the pathology sampling process, doctors face serious occupational health threats, not only suffering long-term physical damage but also enduring psychological stress, exacerbating burnout and impacting work quality. Fundamentally addressing these issues during the pathology sampling process is of great social and professional significance. Summary of the Invention

[0017] Step 6: Tissue staining: Identify the amount of tissue and compare it with the amount of tissue marked by the doctor in the patient code. Once the verification is correct, take the syringe of eosin solution and drip it on the tissue for staining;
