Therefore, when puncturing and sampling tumors, a puncture sampler is needed. Puncture sampling is a diagnostic and treatment technique that inserts a puncture needle into the body cavity to extract secretions for sampling and testing, injects gas or contrast agent into the body cavity for contrast examination, or injects drugs into the body cavity.

[0003] After searching, the patent number is CN211796620U, which discloses a sampler for oncology internal medicine, which can screen the parts that need to be sampled to avoid the collected samples being not ideal, thereby causing errors in the test and thus leading to errors in the judgment of the condition. However, when using the existing tumor interventional puncture sampler, it usually requires the staff to hold it and insert it into the tumor position, which makes it difficult to accurately control the sampling depth and inconvenient to operate.
