[0002] Tumor biopsy, also known as biopsy, is a method of removing a small amount of tissue from the tumor site for pathological examination through surgical resection, fine needle puncture or endoscopic assistance.

[0003] When sampling tumors that are difficult to remove directly through surgery, puncture biopsy is often used. Under the guidance of imaging examinations such as ultrasound, CT or MRI, the puncture point is determined, and a puncture needle is used to pierce the lesion site to remove a small amount of tissue cells for testing. However, during the puncture biopsy process, multiple sampling is required, which is cumbersome and prone to infection.

[0004] In order to reduce the number of puncture biopsies and avoid infection as much as possible, we propose a multifunctional tumor biopsy sampling device. Summary of the invention
