Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a tumor puncture sample extraction device. Background Art

[0002] With the continuous development of medical technology and the progress of society, the application of using sampling devices to collect tumor samples has become more and more extensive. Testing the collected tumor samples plays an important role in tumor diagnosis, treatment and research. For example, doctors can obtain samples directly from patients' tumor tissues for pathological analysis and diagnosis. This helps to determine the type, grade and other characteristics of the tumor, provide patients with more accurate diagnostic results, and guide the formulation of subsequent treatment plans.

[0003] However, in the process of collecting tumor samples using a puncture sampling device, the tumor samples are not easy to separate from the tumor matrix, and there is a problem of inconvenient sampling. The Chinese patent publication number is: CN219439221U (application number: CN202320128409.6) discloses a tumor puncture sampling device, which can effectively separate the tumor sample from the tumor matrix through a resection tool. However, since the blade and the elastic member are directly connected, the longitudinally stretched elastic member is extremely easy to deform under the action of excessive tension, thereby affecting the blade resetting, so there are problems of short life and unstable use.
