What does puncture biopsy needle mean

Bone and soft tissue tumors are serious diseases that endanger human health and life. In recent years, the incidence is increasing gradually, and the age of onset is decreasing gradually. Early detection, correct diagnosis and timely treatment have important influence on the prognosis. With the continuous improvement of examination methods and methods, the diagnostic accuracy is gradually improved, but there are still a large part of tumors do not have typical imaging characteristics, diagnosis is difficult. Correct diagnosis requires a combination of clinical, imaging and pathology. Among them, pathological diagnosis plays a key role in the choice of treatment. Puncture biopsy is the main way to obtain pathological diagnosis. Because limb salvage therapy for malignant tumors has become a major trend, it requires more stringent requirements on sampling methods and methods 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. Puncture biopsy has become the main method for histopathologic diagnosis of bone and soft tissue tumors due to its simple operation, low complications and high accuracy. Therefore, we suggest that the following important principles should be followed before biopsy: 1. The biopsy should be paid as much attention and carefully planned as the surgical plan. Because this is the beginning of cancer treatment, it is a crucial first step, and an incorrect biopsy can have disastrous consequences for the patient. 2. Aseptic operation principles should be strictly observed, and skin preparation, hemostasis and suture should be performed as in conventional surgery. 3. Ensure that the biopsy will not affect the formulation of the surgical plan in the future, and the contaminated area of the biopsy should be completely removed. 4. Ensure that enough representative tissue specimens are available for diagnosis by the pathologist. If the pathologist cannot make a clear diagnosis, he/she should provide detailed clinical and imaging data in time. 5. If the doctor or hospital is not equipped to treat the tumor, the patient should be referred to a doctor or hospital equipped to diagnose and treat the tumor for proper treatment before biopsy.
