Description

Technical Field

[0001] The invention relates to the field of tumor sampling, and in particular to a tumor sampling device for oncology. Background Art

[0002] A tumor refers to a new organism formed by the proliferation of local tissue cells under the action of various tumorigenic factors. Tumor cells will undergo metabolic changes different from those of normal cells. At the same time, tumor cells themselves can adapt to changes in the metabolic environment by switching between glycolysis and oxidative phosphorylation.

[0003] Oncology, like internal medicine, surgery, obstetrics and gynecology, and pediatrics, is a secondary discipline of clinical medicine. It is divided into internal oncology, tumor radiotherapy, and tumor surgery. Internal oncology is mainly engaged in the internal medical treatment of various benign and malignant tumors; tumor radiotherapy is mainly engaged in radiation therapy of tumors; and tumor surgery provides comprehensive treatment with surgery as the main focus.

[0004] When treating tumors in the oncology department, it is necessary to take samples from the lesions for testing. At this time, a tumor sampling device is needed. In the authorized Chinese utility model patent "Announcement No.: CN218899527U, Name: A Tumor Sampler", it is provided with a sampling needle, a sampling groove, a sampling blade, a push ring and a protrusion, and the sampling needle is rotated by using the push ring and the protrusion, so that the sampling groove and the sampling blade can smoothly slice and sample the tumor under the action of rotation. However, in the above application, the sampling blade is directly used for cutting and sampling. During cutting, solid tissue is difficult to remain fixed due to its own flexible characteristics. During cutting, the solid tissue escapes the blade, resulting in less solid tissue cut at a single time and low cutting efficiency. At the same time, the sampling method is difficult to remove the cut sample, and only solid solid tissue is sampled, while it is difficult to sample tissue fluid, resulting in a single sampling type, which is difficult to meet the diagnosis needs of different types of tumors.
