What is the meaning of soft tissue puncture biopsy needle

1. Puncture biopsy is the main method for histopathologic diagnosis of bone and soft tissue tumors. Biopsy is at risk of being abandoned.
2. Puncture biopsy refers to taking a small piece of tissue or mass of the human body through a puncture needle for pathological analysis. The most common are superficial mass puncture pathology, thyroid B-ultrasound location puncture pathology, liver puncture and kidney puncture. However, puncture biopsy has a certain misdiagnosis rate, and sometimes the lesion site cannot be penetrated, so only auxiliary diagnosis can be performed.
3. Because limb salvage therapy for malignant tumors has become a major trend, it requires more stringent requirements on sampling methods and approaches during biopsy. Incorrect biopsy often results in the failure of limb salvage due to contamination of local important structures such as blood vessels and nerve tracts caused by the tumor during sampling, so that the tumor cannot be completely removed. Therefore, before puncture biopsy, it is necessary to fully understand the nature, stage and treatment of the tumor, conduct adequate preoperative planning, and ensure that the selected needle path is located on the surgical incision, so that it can be completely removed during the operation. Therefore, a large number of literatures emphasize that puncture biopsy should be performed by experienced specialists, and it is better to perform biopsy by the surgeon himself, so as to improve the accuracy of puncture biopsy and reduce complications.
